Description

Electrode sheet, tumor electric field therapy system, and electrode sheet type identification method Technical Field

[0001] The present application relates to tumor electric field therapy technology, and in particular to an electrode sheet, a tumor electric field therapy system, and an electrode sheet type identification method. Background Art

[0002] Tumor electric field therapy is a method that uses low-intensity, medium-high frequency alternating electric fields to prevent the formation of spindle microtubules during mitosis in certain tumor cells and inhibit the separation of intracellular organelles during cell division. It induces apoptosis in mitotic cells, thereby achieving the effect of treating tumors.

[0003] Compared with traditional cancer treatment methods, tumor electric field therapy has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them susceptible to tumor electric field therapy. Tumor electric field therapy disrupts the normal aggregation of microtubules by exerting directional forces on polar particles (such as macromolecules and organelles) in cells. These processes may lead to physical damage to the cell membrane and cell apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow will lead to uneven distribution of the electric field around it. At the same time, under the influence of tumor electric field therapy, the electric field intensity at the cleavage furrow is significantly enhanced, and the charged substances in the cell move toward the cleavage furrow, which interferes with or even destroys the formation of the cell structure, and ultimately leads to cell division failure and apoptosis.

[0004] Currently, the tumor electric field therapy system mainly includes an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode sheets electrically connected to the electric field generator through the adapter. The electric field generator transmits the alternating electrical signal for tumor electric field therapy to each electrode sheet through the adapter, and then the alternating electric field is applied to the patient's tumor site through the electrode sheet to perform tumor electric field therapy. Due to the different distribution of tumors, the intensity and coverage of the electric field vary depending on the location of the tumor. For example, when the site is the head, the electric field coverage is not very large, and two pairs of electrode sheets with 9 electrode units can cover it. When the site is the chest and abdomen, the electric field coverage is larger than that of the head, and the number of electrode units required is more than that of the head, such as using electrode sheets with 13, 20, or other more than 9 electrode units.

[0005] During tumor electric field therapy, the electric field applied to the patient will accumulate heat at the corresponding position of the electrode patch on the skin. In order to avoid low-temperature burns on the skin, a temperature sensor needs to be configured at each electrode unit to monitor the skin surface temperature at each electrode unit. Considering factors such as the location of the tumor distribution and the range that tumor electric field therapy needs to cover, when performing tumor electric field therapy, there are situations where two pairs of electrode patches with different numbers of electrode units need to be used in combination. Accordingly, the number of temperature sensors corresponding to electrode patches with different numbers of electrode units is also different. For example, the number of temperature sensors for an electrode patch with 9 electrode patches, an electrode patch with 13 electrode patches, and an electrode patch with 20 electrode patches are all different. The adapter needs to collect the analog temperature signals of 9 temperature sensors, 13 temperature sensors, and 20 temperature sensors respectively, so the type of the corresponding electrode patch needs to be determined. Summary of the Invention

[0007] The second objective of this application is to provide a tumor electric field therapy system.

[0008] The third object of this application is to provide another tumor electric field treatment system.

[0009] The fourth objective of this application is to provide a method for identifying electrode sheet types.

[0010] A fifth objective of this application is to provide a computer-readable storage medium.

[0011] The sixth objective of this application is to provide an adapter for tumor electric field therapy.

[0012] The seventh objective of this application is to provide an electric field generator for tumor electric field therapy.

[0013] To achieve the above-mentioned purpose, the first embodiment of the present application provides an electrode sheet for use in a tumor electric field therapy system, wherein the tumor electric field therapy system includes a switching unit and a control switch, and the electrode sheet includes: a flexible circuit board; a plurality of electrode units and a plurality of temperature detection units arranged on the flexible circuit board, each of the electrode units can apply an alternating electric signal, and each of the temperature detection units is arranged corresponding to an electrode unit to detect the temperature at the corresponding electrode unit, wherein the plurality of electrode units are configured into at least two row groups and at least two column groups; the ground terminals of the temperature detection units in each row group are commonly connected to a ground pin through a control switch connected in series on a ground line; the signal terminals of the temperature detection units in each column group are respectively connected to the corresponding electrode unit. After short-circuiting, they are connected to the switching unit through a dual-purpose signal line to switch the dual-purpose signal line to the temperature sampling point or the alternating power line through the switching unit; when the dual-purpose signal line is connected to the temperature sampling point, the analog temperature signal detected by the corresponding temperature detection unit is sampled based on the temperature sampling point, and the analog temperature signal detected by each sampled temperature detection unit is used to determine the coding array of the corresponding electrode sheet, the coding array includes a first code for indicating that the temperature detection unit is in a normal state, and the type of the corresponding electrode sheet is determined by the first code in the coding array; when the dual-purpose signal line is connected to the alternating power line, the alternating electrical signal is applied to the corresponding electrode unit based on the alternating power line.

[0014] In the embodiment of the present application, the signal ends of the temperature detection units corresponding to the electrode units of the electrode sheet of the tumor electric field therapy system are respectively short-circuited with the corresponding electrode units and then connected to the switching unit via a dual-purpose signal line. The dual-purpose signal line can be switched by the switching unit to be connected to a temperature sampling point or an alternating power line. In this way, when the dual-purpose signal line is connected to the temperature sampling point, the analog temperature signal detected by the corresponding temperature detection unit is sampled based on the temperature sampling point, and when the dual-purpose signal line is connected to the alternating power line, the alternating electric signal is applied to the corresponding electrode unit based on the alternating power line. In this way, temperature sampling and application of the alternating electric signal can be achieved through the dual-purpose signal line. Not only are new AC signal lines (i.e., AC lines) not added, but the original AC signal lines are also eliminated, so that multiple electrode units can be controlled using fewer conductive traces. This not only simplifies the flexible circuit board circuit design of the electrode sheet and does not increase the weight of the electrode sheet, but also achieves comprehensive temperature detection of each electrode unit, and is beneficial to the application of the electrode sheet. At the same time, the analog temperature signal detected by each temperature detection unit is sampled and used to determine the coding array of the corresponding electrode sheet, and the type of the corresponding electrode sheet is determined through the coding array. In this way, the type of the electrode sheet can be automatically identified, thereby realizing temperature collection of different types of electrode sheets without missing any collection or generating interference signals.

[0017] To achieve the above-mentioned purpose, the fourth aspect of the present application provides an electrode sheet type identification method, which is applied to the aforementioned tumor electric field therapy system, and the method includes: determining the temperature detection signal of each electrode unit in each of the electrode sheets; determining the coding array of the corresponding electrode sheet based on the temperature detection signal, and the coding array includes a first code for indicating that the temperature detection unit is in a normal state; and determining the type of the corresponding electrode sheet based on the first code in the coding array.

[0043] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0044] Some examples:

[0045] FIG1 is a schematic diagram of a tumor electric field therapy system 100 according to a first embodiment of the present application. As shown in FIG1 , the tumor electric field therapy system 100 includes at least one pair of electrode sheets 110, an adapter 120 electrically connected to the at least one pair of electrode sheets 110, and an electric field generator 130 electrically connected to the adapter 120. The at least one pair of electrode sheets 110 can be arranged in pairs on the patient's body surface, such as the four electrode sheets 110 shown in FIG1 , where each pair of electrode sheets 110 is arranged on the patient's body surface as a pair. The electric field generator 130 is used to supply power to the at least one pair of electrode sheets 110, thereby generating an alternating electric field between the at least one pair of electrode sheets 110 for treating tumors. The adapter 120 is electrically connected between the at least one pair of electrode sheets 110 and the electric field generator 130, and is used to transmit the alternating electrical signal generated by the electric field generator 130 to the at least one pair of electrode sheets 110. That is to say, the electric field generator 130 is capable of generating an alternating electric signal, and the generated alternating electric signal is transmitted to each electrode sheet 110 through the adapter 120, so that an alternating electric field for treating tumors is generated between the same pair of electrode sheets 110, so as to apply an alternating electric field to the patient's tumor site for tumor treatment.

[0046] As shown in FIG1 , in this embodiment, there are four electrode sheets 110, each of which includes a plurality of electrode units 112 of the same number. Each electrode unit 112 is electrically connected to an adapter 120, and the number of electrode units 112 on each electrode sheet 110 is 20. In other embodiments, the tumor electric field therapy system 100 may have more or fewer electrode sheets 110; in other embodiments, each pair of electrode sheets 110 may have the same number of electrode units 112, while different pairs of electrode sheets 110 may have different numbers of electrode units 112; in still other embodiments, the number of electrode units 112 on each electrode sheet 110 may be 9, 13, 19, etc.

[0047] FIG2 is a schematic diagram of the circuit connection between the electrode sheet 110 and the adapter 120 of the tumor electric field therapy system 100 shown in FIG1 . It is worth noting that the arrangement of the electrode units 112 shown in FIG2 is intended to more clearly illustrate the electrical connection between an electrode sheet 110 and the adapter 120. The arrangement of the electrode units 112 shown in FIG2 does not represent the spatial arrangement of the electrode units 112. In conjunction with FIG1 and FIG2 , the electrode sheet 110 includes: a flexible circuit board 111, a plurality of electrode units 112 electrically connected to the flexible circuit board 111 at intervals, a plurality of temperature detection units 113, and a first cable 116 electrically connected to the flexible circuit board 111. The flexible circuit board 111 is embedded with multiple conductive traces, which include multiple ground lines 118 and multiple dual-purpose signal lines 119. The first cable 116 includes multiple conductors (not shown), each of which is electrically connected to the multiple grounding wires 118 and multiple dual-purpose signal wires 119 of the flexible circuit board 111. In this embodiment, the total number of grounding wires 118 and dual-purpose signal wires 119 embedded in the flexible circuit board 111 does not exceed nine, and therefore the number of conductors in the first cable 116 does not exceed nine.

[0048] The multiple electrode units 112 are arranged into multiple row groups and multiple column groups. In this embodiment, each electrode sheet 110 is provided with 20 electrode units 112. The 20 electrode units 112 are arranged in the order of 1 to 20 for circuit connection, divided into four row groups and five column groups. That is, the 20 electrode units 112 are arranged in four row groups and five column groups for circuit connection. Each electrode unit 112 corresponds to a temperature detection unit 113, and each temperature detection unit 113 has a signal terminal 113B and a ground terminal 113A. The electrode units 112 and temperature detection units 113 are both soldered to the flexible circuit board 111, and the electrode units 112 are short-circuited with the signal terminals 113B of the corresponding temperature detection units 113. Since the multiple temperature detection units 113 are provided in a one-to-one correspondence with the multiple electrode units 112, the multiple temperature detection units 113 are also arranged in four row groups and five column groups for circuit connection. It should be noted that the arrangement here is intended to more clearly illustrate the electrical connection between the electrode sheet 110 and the adapter 120, and does not represent the spatial arrangement of the electrode units 112. The spatial structure may be a roughly array structure as shown in Figure 1, or other structures, such as petal-shaped or scattered, and may be regular or irregular. The electrode units 112 are configured to apply an alternating electrical signal to the patient's tumor site. The temperature detection unit 113 is configured to detect the temperature of the patient's body surface to which the electrode sheet 110 is applied, that is, the temperature at the corresponding electrode unit 112, and output the temperature detection signal to an external device such as the adapter 120. In this embodiment, the multiplexed signal lines 119 of the flexible circuit board 111 are respectively arranged in a one-to-one correspondence with the multiple column groups of the electrode units 112, and are configured to transmit the alternating electrical signal generated by the electric field generator 130 to each electrode unit 112 in the corresponding column group. That is, the electrode units 112 in the same column group are short-circuited via the same dual-purpose signal line 119 on the flexible circuit board 111, while the electrode units 112 in different column groups are connected in parallel via different dual-purpose signal lines 119 on the flexible circuit board 111. The dual-purpose signal lines 119 on the flexible circuit board 111 are electrically connected to the first cable 116 and then to the electric field generator 130 via the adapter 120. Furthermore, the dual-purpose signal lines 119 on the flexible circuit board 111 receive the alternating electrical signal generated by the electric field generator 130 via the first cable 116 and the adapter 120.

[0049] Multiple grounding lines 118 are provided in a one-to-one correspondence with the multiple row groups of electrode units 112. Multiple grounding lines 118 are used to sequentially short-circuit each temperature detection unit 113 in each row group to ground. Specifically, the grounding terminals 113A of the temperature detection units 113 in the same row group are all short-circuited via the same grounding line 118 on the flexible circuit board 111. The grounding terminals 113A of the temperature detection units 113 in different row groups are connected in parallel via different grounding lines 118 on the flexible circuit board 111. During the temperature detection period, only one of the multiple grounding lines 118 is conductive at any given time; the remaining grounding lines 118 are disconnected.

[0050] Each of the multiplexed dual-purpose signal lines 119 is further configured to short-circuit the signal terminal 113B of at most one temperature detection unit 113 in each row group to an external device for receiving a detection signal. Each of the multiplexed dual-purpose signal lines 119 is connected to a different signal terminal 113B of each temperature detection unit 113 to prevent the dual-purpose signal lines 119 from subsequently outputting duplicate signals. Specifically, when the number of electrode units 112 in a row group is the same as the number of dual-purpose signal lines 119, each dual-purpose signal line 119 is electrically connected to the signal terminal 113B of a different temperature detection unit 113 in the row group. When the number of electrode units 112 in a row group is less than the number of dual-purpose signal lines 119, at least one dual-purpose signal line 119 is not electrically connected to the signal terminal 113B of a temperature detection unit 113, and each of the remaining dual-purpose signal lines 119 is electrically connected to the signal terminal 113B of a different temperature detection unit 113 in the row group. In this embodiment, the external device for receiving the detection signal is an adapter 120. The signal terminals 113B of the temperature detection units 113 in different column groups are connected in parallel via different dual-purpose signal lines 119 on the flexible circuit board 111. The signal terminals 113B of the temperature detection units 113 in the same column group are all short-circuited to the same dual-purpose signal line 119 on the flexible circuit board 111.

[0051] In this embodiment, when each electrode unit 112 is equipped with a temperature detection unit 113 for temperature detection, the above-mentioned circuit design is used to reduce the number of conductors in the first cable 116, thereby preventing the cable from becoming thicker and the cable from becoming harder, which increases the difficulty of cable fixing. At the same time, the increase in the number of conductors in the first cable 116 prevents the adhesion effect between the electrode sheet 110 and the patient's body surface corresponding to the tumor site. The ground wire 118 and the dual-purpose signal wire 119 embedded in the flexible circuit board 111 are a total of 9 lines. Specifically, in this embodiment, the ground wire 118 embedded in the flexible circuit board 111 is 4 lines, and the dual-purpose signal wire 119 is 5 lines. The number of conductive lines electrically connected to the ground wire 118 of the electrode sheet 110 in the tumor electric field therapy system 100 is related to the number of row groups M of the electrode units 112, which is greater than or equal to the number of row groups of the electrode units 112, and M is a positive integer. The number of conductive traces electrically connected to the dual-purpose signal lines 119 in the tumor therapy field system 100 is related to the number N of electrode unit column groups 112, and is greater than or equal to the number N of electrode unit column groups 112, where N is a positive integer. The number of traces L embedded within the flexible circuit board 111 of the electrode sheet 110 is equal to the sum of the number of ground traces 118 and the number of dual-purpose signal traces 119. In this embodiment, the number of ground traces 118 is equal to the number M of electrode unit row groups 112, and the number of dual-purpose signal traces 119 is equal to the number N of electrode unit column groups 112.

[0052] In terms of spatial structure, multiple electrode units 112 are spaced apart and arranged in a roughly two-dimensional array on the flexible circuit board 111. As shown in FIG1 , the electrode sheet 110 in this embodiment includes 20 electrode units 112 and 20 temperature detection units 113 corresponding to the electrode units 112. The 20 electrode units 112 are arranged in an array of four rows and six columns. The first and fourth rows each contain four electrode units 112, and the second and third rows each contain six electrode units 112. The four electrode units 112 in each row of the first and fourth rows are located in each of the second to fifth columns, and the six electrode units 112 in each row of the second and third rows are located in each of the first to sixth columns.

[0053] As shown in Figure 1, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetric manner. For example, the electrode units 112 located in the third column of the first row, the third column of the second row, the third column of the third row, and the third column of the fourth row are connected by a column-directed connecting strip (unnumbered), and at the same time, the electrode units 112 located in the fifth column of the first row, the fifth column of the second row, the fifth column of the third row, and the fifth column of the fourth row are connected by a column-directed connecting strip (unnumbered). Each electrode sheet 110 has a free end. For example, at least one electrode unit 112 among the plurality of electrode units 112 is connected to at most one other electrode unit 112. For example, the electrode units 112 located in the first row and second column, the second row and first column, the second row and second column, the third row and first column, the third row and second column, and the fourth row and second column are not connected by connecting strips in the column direction, thereby forming an open space (unnumbered), and the open space (unnumbered) is adjustable. For example, the position of the electrode unit 112 in the first row and second column is movable compared to the position of the electrode unit 112 in the first row and third column, and the electrode unit 112 in the second row and first column is movable compared to the electrode unit 112 in the second row and second column. The position of the electrode unit 112 is movable, the position of the electrode unit 112 in the first column of the third row is movable compared to the position of the electrode unit 112 in the second column of the third row, and the position of the electrode unit 112 in the second column of the fourth row is movable compared to the position of the third column of the fourth row. Therefore, when the electrode sheet 110 is applied to the patient's body surface, by adjusting the positions of the electrode units 112 in the second column of the first row, the first column of the second row, the first column of the third row and the second column of the fourth row, the open space (unnumbered) between the electrode units 112 in the corresponding rows can be adjusted, thereby increasing the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation, and at the same time facilitating the patient to adjust the position of the electrode unit 112 based on the fever situation.Similarly, the electrode units 112 located in the first row and fourth column, the second row and fourth column, the second row and sixth column, the third row and fourth column, the third row and sixth column, and the fourth row and fourth column are not connected by connecting strips in the column direction, thereby forming an open space (unnumbered), and the open space (unnumbered) is adjustable. For example, the position of the electrode unit 112 in the first row and fourth column is movable compared to the position of the electrode unit 112 in the first row and fifth column, the position of the electrode unit 112 in the second row and fourth column and the position of the electrode unit 112 in the second row and fifth column is movable compared to the position of the electrode unit 112 in the third row and sixth column. 2 is movable, and the position of the electrode unit 112 in the fourth row and fourth column is movable compared to the electrode unit 112 in the fourth row and fifth column. Therefore, when the electrode sheet 110 is applied to the patient's body surface, by adjusting the positions of the electrode units 112 in the first row and fourth column, the second row and fourth column, the second row and sixth column, the third row and sixth column, and the fourth row and fourth column, the open space (unnumbered) between the electrode units 112 in the corresponding rows can be adjusted. This can increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating the heat dissipation, and at the same time helping the patient to adjust the position of the electrode unit 112 based on the fever situation or the skin condition of the area where the electrode sheet 110 is applied.

[0054] As shown in FIG1 , in terms of spatial structure, the four electrode units 112 in the first row can be divided into Region 1. The four electrode units 112 in the second row, first column, third row, first column, fourth row, second column, and fourth row, third column can be divided into Region 2. The four electrode units 112 in the second row, sixth column, third row, sixth column, fourth row, fourth column, and fourth row, fifth column can be divided into Region 3. The four electrode units 112 in the second row, second column, second row, third column, third row, second column, and third row, third column can be divided into Region 4. The four electrode units 112 in the second row, fourth column, second row, fifth column, third row, fourth column, and third row, fifth column can be divided into Region 5. The electrode units 112 in each region (1-5) correspond to a column group in the circuit connection shown in FIG2 , and the corresponding 20 electrode units 112 are arranged in four rows and five columns in the circuit connection. In other embodiments, the 20 electrode units 112 can also be arranged in other ways. Of course, in other embodiments, the electrode sheet 110 may also have other numbers of electrode units 112. In short, the implementation of the present application is not limited by the number and arrangement of the electrode units 112 of the electrode sheet 110.

[0055] Each electrode unit 112 can apply an alternating electric signal, and the electrode sheets 110 configured in pairs are used to apply an alternating electric field to the patient's tumor site. Optionally, the electrode unit 112 is a dielectric element, such as a ceramic sheet, which can also be a polymer dielectric layer composed of a polymer material. Each temperature detection unit 113 is provided corresponding to an electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be provided at any position of the corresponding electrode unit 112. In this embodiment, each electrode unit 112 is provided with a through-hole 1121, and the through-hole 1121 is suitable for installing the temperature detection unit 113. Specifically, the middle part of each electrode unit 112 has a through-hole 1121, and the through-hole 1121 of each electrode unit 112 accommodates a corresponding temperature detection unit 113. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115. The temperature sensor 114 has a signal terminal 114B and a ground terminal 114A. The diode 115 has an anode 115B and a cathode 115A. The anode 115B of the diode 115 is connected to the ground terminal 114A of the temperature sensor 114. The cathode 115A of the diode 115 serves as the ground terminal 113A of the temperature detection unit 113. The signal terminal 114B of the temperature sensor 114 serves as the signal terminal 113B of the temperature detection unit 113. The temperature sensor 114 can be a thermistor or other temperature sensor other than a thermistor. Each temperature sensor 114 is provided with a corresponding diode 115. The diode 115 is connected in series with the temperature sensor 114 of the same electrode unit 112. The diode 115 can prevent reverse current flow, thereby preventing the detection signal from other electrode units 112 from affecting the temperature sensor 114.

[0056] As shown in FIG2 , the electrode sheet 110 of this embodiment includes four grounding wires 118 , each of which is used to ground the ground terminals 113A of the temperature detection units 113 in the same row group. The four grounding wires 118 of the electrode sheet 110 are respectively a first grounding wire 118 - 1, a second grounding wire 118 - 2, a third grounding wire 118 - 3, and a fourth grounding wire 118 - 4. Of the four row groups of the electrode sheet 110 , the first row group includes electrode units 112 - 1 to 112 - 5 , the second row group includes electrode units 112 - 6 to 112 - 10 , the third row group includes electrode units 112 - 11 to 112 - 15 , and the fourth row group includes electrode units 112 - 16 to 112 - 20 . Specifically, the first grounding wire 118-1 is used to ground the temperature detection units 113 corresponding to the electrode units 112-1 to the electrode units 112-5 in the first row group; the second grounding wire 118-2 is used to ground the temperature detection units 113 corresponding to the electrode units 112-6 to the electrode units 112-10 in the second row group; the third grounding wire 118-3 is used to ground the temperature detection units 113 corresponding to the electrode units 112-11 to the electrode units 112-15 in the third row group; and the fourth grounding wire 118-4 is used to ground the temperature detection units 113 corresponding to the electrode units 112-16 to the electrode units 112-20 in the fourth row group. It should be noted that these grounding wires 118 can be selectively closed or disconnected, which can be achieved by connecting each grounding wire 118 in series with a control switch 124, that is, the grounding terminals 113A of the temperature detection units 113 corresponding to each electrode unit 112 in each row group are connected to the ground pin through a control switch 124, which will be described in detail below. The above-mentioned "grounding the electrode unit 112" can refer to grounding the grounding terminal 114A of the temperature sensor 114 corresponding to each electrode unit 112, or it can refer to connecting the diode 115 in series with the temperature sensor 114 corresponding to the same electrode unit 112 and grounding them together. In short, each grounding wire 118 short-circuits the grounding terminals 113A of the temperature detection units 113 corresponding to all electrode units 112 in each row group and grounds them.

[0057] As shown in FIG2 , the electrode sheet 110 of this embodiment further includes five dual-purpose signal lines 119. One end of each dual-purpose signal line 119 is connected to a signal terminal 113B of each electrode unit 112 and the corresponding temperature detection unit 113 in each column group, and the other end is connected to an adapter 120 for receiving temperature detection signals and transmitting alternating electrical signals. That is, for each row group, each dual-purpose signal line 119 can selectively connect to the signal terminal 113B of one electrode unit 112 and the corresponding temperature detection unit 113, or not connect to the signal terminal 113B of any electrode unit 112 and the corresponding temperature detection unit 113 in that row group, thereby preventing the dual-purpose signal lines 119 from subsequently outputting duplicate signals. Specifically, the five dual-purpose signal lines 119 of the electrode sheet 110 include a first dual-purpose signal line 119-1, a second dual-purpose signal line 119-2, a third dual-purpose signal line 119-3, a fourth dual-purpose signal line 119-4, and a fifth dual-purpose signal line 119-5. One end of the first dual-purpose signal line 119-1 is connected to the four electrode units 112, namely, electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16, and the signal end 113B of the temperature detection unit 113 corresponding thereto; one end of the second dual-purpose signal line 119-2 is connected to the four electrode units 112, namely, electrode unit 112-2, electrode unit 112-7, electrode unit 112-12, and electrode unit 112-17, and the signal end 113B of the temperature detection unit 113 corresponding thereto; one end of the third dual-purpose signal line 119-3 is connected to the four electrode units 112, namely, electrode unit 112-3, electrode unit 112-8, and electrode unit 112-17, and the signal end 113B of the temperature detection unit 113 corresponding thereto; One end of a fourth dual-purpose signal line 119-4 is connected to the four electrode units 112 (electrode units 112-11, 112-13, 112-18) and the signal terminals 113B of their corresponding temperature detection units 113. One end of a fourth dual-purpose signal line 119-4 is connected to the four electrode units 112 (electrode units 112-4, 112-9, 112-14, and 112-19) and the signal terminals 113B of their corresponding temperature detection units 113. One end of a fifth dual-purpose signal line 119-5 is connected to the four electrode units 112 (electrode units 112-5, 112-10, 112-15, and 112-20) and the signal terminals 113B of their corresponding temperature detection units 113. In short, each dual-purpose signal line 119 parallel-circuits the electrode units 112 and the signal terminals 113B of their corresponding temperature detection units 113 in the same column group and is used to connect to an external device. It should be noted that these dual-purpose signal lines 119 can selectively transmit alternating electrical signals or receive temperature detection signals. This can be achieved by connecting each dual-purpose signal line 119 in series with a bidirectional switch 125 and coordinating the closing or opening of the ground line 118.That is, after the signal terminals 113B of the temperature detection units 113 in each column group are short-circuited with the corresponding electrode units 112, they are connected to a switching unit (not labeled) through a dual-purpose signal line 119. The switching unit (not labeled) includes a plurality of bidirectional switches 125. Each bidirectional switch 125 is configured to switch the dual-purpose signal line 119 to connect to a temperature sampling point (not labeled) or an alternating power line 127. When the dual-purpose signal line 119 is connected to the temperature sampling point (not labeled), the alternating power line 127 is configured to control the switch 124. The switching state is such that the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group is sampled based on the temperature sampling point (unnumbered), and the temperature detection signal detected by each temperature detection unit 113 is sampled and used to determine the coding array of the corresponding electrode sheet 110, and the type of the corresponding electrode sheet 110 is determined by the coding array, and when the dual-purpose signal line 119 is connected to the alternating power line 127, the electrode unit 112 of at least one column group is applied with an alternating electric signal based on the alternating power line 127, which will be described in detail below.

The flexible printed circuit board 111 is electrically connected to the first cable 116. The multiple ground lines 118 and multiplexed signal lines 119 embedded within the flexible printed circuit board 111 are electrically connected to corresponding wires (not shown) within the first cable 116.

The adapter 120 is connected between the electrode sheets 110 and the electric field generator 130. The electric field generator 130 provides alternating electrical signals to the multiple electrode units 112 of the electrode sheet 110 via the adapter 120 and the dual-purpose signal line 119 of the electrode sheet 110, or receives temperature detection signals output by the temperature detection units 113 corresponding to the multiple electrode units 112. The adapter 120 transmits the alternating electrical signals generated by the electric field generator 130 to the dual-purpose signal line 119 of the electrode sheet 110, and is also configured to receive the temperature detection signals output by the multiplexed dual-purpose signal line 119 of the electrode sheet 110.

The first power supply module 128 provides a DC power supply VCC for each electronic component of the adapter 120. The adapter 120 also includes multiple circuit lines (unnumbered), which are electrically connected to the multiple ground lines 118 and the multiplexed signal lines 119 in the flexible circuit board 111 of the corresponding electrode sheet 110 through the first cables 116 of the corresponding electrode sheet 110. The multiple circuit lines (unnumbered) include an alternating power line 127 that transmits an alternating electrical signal to the corresponding electrode sheet 110 and is electrically connected to the dual-purpose signal line 119 in the flexible circuit board 111 of the corresponding electrode sheet 110, multiple circuit lines (unnumbered) that are electrically connected one-to-one with the dual-purpose signal line 119 in the flexible circuit board 111 of the corresponding electrode sheet 110 and are used to supply power to each temperature detection unit 113 of the electrode sheet 110 or transmit the temperature detection signal of the electrode sheet 110, and multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiple ground lines 118 in the flexible circuit board 111 of the corresponding electrode sheet 110.

The number of groups of control switches 124 is the same as the number of groups of bidirectional switching switches 125 and is not less than the number of electrode sheets 110. Optionally, the number of groups of control switches 124 and the number of groups of bidirectional switching switches 125 are both the same as the number of electrode sheets 110.

The bidirectional switch 125 may also be an electronic switch, and each bidirectional switch 125 may be switched by an additional first controller 121.

[0065] In this embodiment, the plurality of sets of bidirectional switches 125 are all electronic switches. The first controller 121 is in communication with the plurality of sets of bidirectional switches 125 and is configured to control the plurality of bidirectional switches 125 in each set of bidirectional switches 125 to switch between their respective terminals 1 and 2, and to coordinate the closing or opening of the corresponding control switch 124 to continuously monitor the patient's body surface temperature detected by all temperature detection units 113 on the electrode sheet 110 or to transmit an alternating electrical signal to the patient.

[0066] In this embodiment, each set of ADC units 122 is electrically connected to one end of each of the plurality of bidirectional switches 125 in the corresponding set of bidirectional switches 125 via a multi-channel circuit line (not numbered) within the adapter 120, and is configured to receive the temperature detection signal transmitted by the multiplexed signal line 119 of the corresponding electrode sheet 110 and convert the temperature detection signal from an analog signal to a digital temperature signal. Each set of ADC units 122 includes a plurality of detection channels A, B, C, D, and E, which are arranged in a one-to-one correspondence with the corresponding temperature sampling points (not numbered). Each detection channel A, B, C, D, and E is connected to a corresponding one of the multiplexed signal lines 119 via the corresponding bidirectional switch 125. As shown in FIG2 , each set of ADC units 122 includes a total of five detection channels A, B, C, D, and E, namely a first detection channel A, a second detection channel B, a third detection channel C, a fourth detection channel D, and a fifth detection channel E. The first detection channel A is connected to the first dual-purpose signal line 119-1 via one end of the first bidirectional switch 125-1, the second detection channel B is connected to the second dual-purpose signal line 119-2 via one end of the second bidirectional switch 125-2, the third detection channel C is connected to the third dual-purpose signal line 119-3 via one end of the third bidirectional switch 125-3, the fourth detection channel D is connected to the fourth dual-purpose signal line 119-4 via one end of the fourth bidirectional switch 125-4, and the fifth detection channel E is connected to the fifth dual-purpose signal line 119-5 via one end of the fifth bidirectional switch 125-5.

[0067] In this embodiment, the first communication unit 126 is configured to obtain digital temperature signals output by multiple sets of ADC units 122 and send the digital temperature signals to the electric field generator 130. The electric field generator 130 is also configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 112 of the electrode sheet 110 based on the received digital temperature signals. For example, when any of the multiple digital temperature signals received exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 113 corresponding to at least one electrode unit 112 in the electrode sheet 110 exceeds a preset temperature threshold (e.g., 41°C, 42°C, etc.). At this time, the voltage or current of the alternating electrical signal output by the electric field generator 130 can be appropriately reduced to prevent the electrode units 112 of the electrode sheet 110 from becoming too hot when the alternating electrical signal is applied, thereby causing low-temperature burns to the patient's skin. The above-mentioned preset temperature threshold and preset threshold can be determined based on the human body safety threshold. The first communication unit 126 is controlled by the first controller 121 and serially transmits the digital temperature signals converted by the multiple sets of ADC units 122.

[0071] The working principle of the tumor electric field treating system 100 of this embodiment will be described in detail below with reference to FIG. 2 to FIG. 4 .

[0072] Specifically, when it is necessary to detect the temperature of each electrode unit 112 of a certain electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls one end of each of the multiple bidirectional switching switches 125 of a group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be turned on and the two ends to be disconnected, so as to disconnect the alternating electric signal applied to the electrode sheet 110; at the same time, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the control switches 124 of a group of control switches 124 electrically connected to the electrode sheet 110 to be turned on in sequence and in a time-sharing manner. At this time, the temperature detection signals collected by each temperature detection unit 113 corresponding to each electrode unit 112 of each row group of the electrode sheet 110 can be collected in a time-sharing manner through multiple detection channels A, B, C, D, and E of a group of ADC units 122 corresponding to the electrode sheet 110. Each detection channel A, B, C, D, and E of each group of ADC units 122 only collects the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of the same row group of the electrode sheet 110 at the same time, and the above-mentioned temperature detection signals can be represented by voltage values. Among the four control switches 124 in a group of control switches 124 corresponding to the electrode sheet 110, only one control switch 124 can be turned on at the same time, and the other three are turned off. All five bidirectional switches 125 in a group of bidirectional switches 125 corresponding to the group of ADC units 122 are switched to their respective ends 1 so that each dual-purpose signal line 119 of the electrode sheet 110 is electrically connected to the corresponding detection channel A, B, C, D, and E of the corresponding ADC unit 122 in a one-to-one correspondence and is turned on. With this arrangement, the group of ADC units 122 can collect the voltage values ​​of all temperature detection units 113 corresponding to the electrode units 112 in the same row group that are short-circuited with the ground line 118 corresponding to the turned-on control switch 124.

[0073] Specifically, when the control switch 124-1 is closed, the control switches 124-2, 124-3, and 124-4 are all opened, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4, and the fifth bidirectional switch 125-5 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-1 to 112-5 of the first row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-6 to 112-20 of the remaining row groups are powered off, and the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11, and 112-16 of the first detection channel A of the group of ADC units 122 are short-circuited. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-1 is connected to ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-6, 112-11, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the resistance of the temperature detection unit 113 corresponding to electrode unit 112-1 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-1 is effectively operating on the first detection channel A of the set of ADC units 122. The temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-1. Similarly, the voltage value collected by the second detection channel B in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-2. The voltage value collected on the third detection channel C in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-3. The voltage value collected on the fourth detection channel D in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-4. The voltage value collected on the fifth detection channel E in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-5.

[0074] When the control switch 124-2 is closed, the control switch 124-1, the control switch 124-3 and the control switch 124-4 are all opened, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4 and the fifth bidirectional switch 125-5 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-6 to the electrode units 112-10 of the second row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to the electrode units 112-5 and the electrode units 112-11 to the electrode units 112-20 of the remaining row groups are powered off, and the electrode units 112-1, the electrode units 112-6, the electrode units 112-11 and the electrode units 112-16 are short-circuited on the first detection channel A of the group of ADC units 122. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-6 is connected to ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-11, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the signal terminals 113B of the corresponding temperature detection units 113 do not affect the resistance of the temperature detection unit 113 corresponding to electrode unit 112-6. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-6 is effectively operating on the first detection channel A of the set of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Similarly, the voltage value collected by the second detection channel B of the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-7. The voltage value collected on the third detection channel C in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-8. The voltage value collected on the fourth detection channel D in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-9. The voltage value collected on the fifth detection channel E in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-10.

[0075] When the control switch 124-3 is closed, the control switches 124-1, 124-2 and 124-4 are all opened, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4 and the fifth bidirectional switch 125-5 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-11 to 112-15 of the third row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-10 and the electrode units 112-16 to 112-20 of the remaining row groups are powered off, and the electrode units 112-1, 112-6, 112-11 and 112-16 on the first detection channel A of the group of ADC units 122 are short-circuited. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-11 is connected to ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the resistance of the temperature detection unit 113 corresponding to electrode unit 112-11 is not affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-11 is effectively operating on the first detection channel A of the set of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Similarly, the voltage value collected by the second detection channel B of the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-12. The voltage value collected by the third detection channel C in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-13. The voltage value collected by the fourth detection channel D in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-14. The voltage value collected by the fifth detection channel E in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-15.

[0076] When the control switch 124-4 is closed, the control switches 124-1, 124-2, and 124-3 are all opened, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4, and the fifth bidirectional switch 125-5 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-16 to 112-20 of the fourth row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-15 of the remaining row groups are powered off, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-15 of the remaining row groups are short-circuited on the first detection channel A of the ADC unit 122 of the group. 3, since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-16 is connected to the ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-11 are all disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-16 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-16 is effectively operating on the first detection channel A of the group of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Similarly, the voltage value collected by the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-17. The voltage value collected on the third detection channel C in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-18. The voltage value collected on the fourth detection channel D in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-19. The voltage value collected on the fifth detection channel E in the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-20.

[0077] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all electrode units 112 of a certain electrode sheet 110 by controlling a set of bidirectional switching switches 125 and a set of control switches 124 that are electrically connected to the electrode sheet 110. That is, the switching unit (unnumbered) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be connected to the corresponding temperature sampling points (unnumbered) at the same time, and by configuring the switching state of the corresponding control switches 124, the temperature detection signals detected by the corresponding temperature detection units 113 in each row group are sampled based on the corresponding temperature sampling points (unnumbered). Similarly, the temperature detection signals of the temperature detection units 113 of each electrode unit 112 of other electrode sheets 110 can be obtained.

[0078] The first controller 121 or the second controller 131, the plurality of ADC units 122 and the plurality of bidirectional switches 125 can automatically perform operations according to pre-programmed program codes. For example, the first controller 121 or the second controller 131 first controls all the bidirectional switches 125 in the corresponding group of bidirectional switches 125 to switch to end 1 so that all ends 1 of the bidirectional switches 125 are turned on and all ends 2 are turned off, so that the dual-purpose signal lines 119 of the corresponding electrode sheet 110 are electrically connected to the corresponding group of ADC units 122. Then, the first control switch 124-1 in the corresponding group of control switches 124 is closed, and the remaining control switches 124-2 to 124-4 in the group of control switches 124 are turned off. During this period, the ADC units 122 in the corresponding group of control switches 124 are turned off. Each detection channel A, B, C, D, and E of the ADC unit 122 obtains the temperature detection signals of each temperature detection unit 113 corresponding to each electrode unit 112 in the first row group of the corresponding electrode sheet 110, converts them into digital temperature signals, and stores them in a separately provided memory. Then, after a preset time interval, the first controller 121 or the second controller 131 closes the second control switch 124-2 in the set of control switches 124 and opens the first control switch 124-1, the third control switch 124-3, and the fourth control switch 124-4 in the set of control switches 124. During this period, each detection channel A, B, C, D, and E of the ADC unit 122 obtains the temperature detection signals of each temperature detection unit 113 corresponding to each electrode unit 112 in the second row group. By sequentially turning on each control switch 124 in the set of control switches 124, the temperature detection signals of all temperature detection units 113 on the electrode sheet 110 can be obtained. Similarly, through this operation, the temperature detection signals of all temperature detection units 113 on at least one pair of electrode sheets 110 are obtained.

[0079] It should be noted that, in other embodiments, a group of bidirectional switching switches 125 and a group of control switches 124 electrically connected to a certain electrode sheet 110 can be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to realize the collection of temperature detection signals of the temperature detection units 113 corresponding to some electrode units 112 of the electrode sheet 110 in the same temperature collection time period. For example, when only the first bidirectional switch 125-1 is switched to its 1 end, the first control switch 124-1 can be controlled to be closed first, and the second control switch 124-2, the third control switch 124-3 and the fourth control switch 124-4 are all disconnected. At this time, only the temperature detection unit 113 corresponding to the electrode unit 112-1 of the first row group is energized, and the signal end 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 is short-circuited on the first detection channel A of the group of ADC units 122. Therefore, the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-1; then, the second control switch 124-2 is controlled to be closed, and the first control switch 124-1, the third control switch 124-3 and the fourth control switch 124-4 are all disconnected. Control switches 124-4 are all open, and the ADC unit 122 in this group will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Then, the third control switch 124-3 is closed, and the first, second, and fourth control switches 124-2, 124-4 are all open. At this point, the ADC unit 122 in this group will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Finally, the fourth control switch 124-4 is closed, and the first, second, and third control switches 124-1, 124-2, and 124-3 are all open. At this point, the ADC unit 122 in this group will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Thus, within the same acquisition time period, only the temperature detection signals of the temperature detection units 113 corresponding to one column group of electrode units 112 can be sampled. Similarly, the temperature detection signals of the temperature detection units 113 corresponding to other column groups of electrode units 112 can be sampled within other acquisition time periods. That is, the switching unit (unnumbered) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the corresponding temperature sampling point (unnumbered), and by configuring the on / off state of the control switch 124, the temperature detection signal detected by each temperature detection unit 113 in each column group is sampled separately. It should be noted that in other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of two, three, or four column groups can also be sampled within the same sampling time period, which will not be further described here.

[0080] Specifically, when it is necessary to apply an alternating electric signal to each electrode unit 112 of a certain electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the two ends of each of the multiple bidirectional switching switches 125 of a group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be turned on and one end to be disconnected, and at the same time controls all the multiple control switches 124 of a group of control switches 124 electrically connected to the electrode sheet 110 to be disconnected, and controls a power supply switch 133 electrically connected to the electrode sheet 110 to be turned on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electric signal to each electrode unit 112 of the electrode sheet 110 through the alternating power line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be connected to the alternating power line 127 at the same time, so that the electrode units 112 of at least two column groups are simultaneously applied with alternating electrical signals based on the alternating power line 127.

[0081] It should be noted that, in other embodiments, a group of bidirectional switches 125 electrically connected to a certain electrode sheet 110 can be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to apply alternating electric signals to some electrode units 112 of the electrode sheet 110 in the same time period. For example, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls only the two ends of the first bidirectional switch 125-1 among the multiple bidirectional switches 125 of a group of bidirectional switches 125 electrically connected to the electrode sheet 110 to be turned on and one end to be turned off, and at the same time controls all the multiple control switches 124 of a group of control switches 124 electrically connected to the electrode sheet 110 to be turned off, and controls a power supply switch 133 electrically connected to the electrode sheet 110 to be turned on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electric signal to the first column group electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16 of the electrode sheet 110 through the alternating power line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the dual-purpose signal line 119 corresponding to each column group to be connected to the alternating power line 127, so that the electrode units 112 of each column group are simultaneously applied with an alternating electrical signal based on the alternating power line 127. It should be noted that in other embodiments, the alternating electrical signal can also be applied simultaneously to the electrode units 112 of two, three, or four column groups within the same time period, which will not be further described in detail here.

[0082] Specifically, when it is necessary to determine the type of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can first sample the temperature detection signal detected by each temperature detection unit 113 in the aforementioned manner, and then determine the coding array of the corresponding electrode sheet 110 based on the sampled temperature detection signal detected by each temperature detection unit 113, and determine the type of the corresponding electrode sheet 110 according to the coding array. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, whose characteristic is that the higher the temperature, the smaller the resistance, and the lower the temperature, the larger the resistance. Since the electrode sheet 110 is applied to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a negative temperature coefficient thermistor with a temperature range of 0°C to 50°C can be selected. For example, you can choose the thermistor model NCP18XH103D03RB. When the sensed temperature is 0°C, the corresponding resistance is approximately 27.45KΩ; when the sensed temperature is 25°C, the corresponding resistance is approximately 10.0KΩ; when the sensed temperature is 50°C, the corresponding resistance is approximately 4.16KΩ.

[0083] As shown in FIG5 , when any control switch 124 is turned on, the DC power supply VCC sequentially provides DC power to the voltage divider resistor 123, the temperature sensor 114, and the diode 115. The ADC unit 122 in the adapter 120 collects the voltage between the temperature sensor 114 and the voltage divider resistor 123 through the corresponding acquisition channel, that is, the voltage divided by the temperature sensor 114, the diode 115, and the voltage divider resistor 123, and obtains an AD sampling value, that is, a voltage value (the voltage value of the thermistor), as shown in the following formula (1): VADC=(VCC-VD)×R / (Rz+R) (1)

[0084] Among them, VADC is the AD sampling value, that is, the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of the diode 115, R is the resistance of the thermistor, and Rz is the resistance of the voltage divider resistor.

[0085] Assuming that the voltage drop VD of the diode 115 is 0.3V and the resistance Rz of the voltage divider resistor 123 is 10KΩ, then when the temperature sensed by the temperature sensor 114 is 0°C, the corresponding resistance is approximately 27.45KΩ. Based on formula (1), the corresponding AD sampling value V0 = (3.3-0.3) × 27.45 / (10 + 27.45) = 2.20V can be obtained; when the temperature sensed by the temperature sensor 114 is 25°C, the corresponding The resistance is approximately 10.0KΩ. Based on formula (1), the corresponding AD sampling value V25 = (3.3-0.3) × 10 / (10+10) = 1.50V can be obtained. When the temperature sensed by temperature sensor 114 is 50°C, the corresponding resistance is approximately 4.16KΩ. Based on formula (1), the corresponding AD sampling value V50 = (3.3-0.3) × 4.16 / (10+4.16) = 0.88V can be obtained. When temperature sensor 114 is disconnected, for example, due to abnormal welding of temperature sensor 114 or open circuit of temperature sensor 114, the corresponding AD sampling value can be 3.3V. When temperature sensor 114 and diode 115 are short-circuited, the corresponding AD sampling value can be 0V.

[0086] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, and the temperature sensor 114 detects different voltage values ​​corresponding to different temperatures, the voltage value collected by the ADC unit 122 can be reasonably segmented for distinction, and the voltage value can be converted into a corresponding code to identify the type of the electrode sheet 110, that is, the number of electrode units 112 on the electrode sheet 110.

[0087] Specifically, taking the example that the temperature sensor 114 senses a temperature within the range of 0°C to 50°C, and the AD sampling value obtained by the ADC unit 122, that is, the voltage value range is 0.88V to 2.20V, considering the detection error factor, etc., the voltage value range can be appropriately enlarged to 0.5V to 3V.

[0088] When the AD sampling value obtained by the ADC unit 122 is greater than 0.5V and less than 3V, the corresponding acquisition code is 1; when the AD sampling value obtained by the ADC unit 122 is less than or equal to 0.3V, the corresponding acquisition code is 0; when the AD sampling value obtained by the ADC unit 122 is greater than or equal to 3.1V, the corresponding acquisition code is 2. Therefore, in the corresponding detection bits numbered 1 to 20 of the electrode sheet 110, if the temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if the temperature sensor 114 is present, the corresponding code is 1, i.e., the first code; if the temperature sensor 114 is absent or disconnected, the corresponding code is 2, i.e., the second code.

[0089] Referring to Figure 5, when sampling, no matter which type of electrode sheet 110 is used (i.e., the number of electrode units 112 or temperature sensors 114 of the electrode sheet 110 is any number less than or equal to 20), the ADC unit 122 obtains 20 AD sampling values ​​each time it acquires, and after each acquisition is completed, a 20-bit coding array is formed based on the 20 AD sampling values. Each type of electrode sheet 110 has a corresponding coding array, wherein different electrode sheets with different numbers of electrode units correspond to different numbers of first codes, thereby obtaining different coding arrays. Therefore, the type of the electrode sheet can be automatically identified by the first code in the coding array.

[0090] The first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the code array of the corresponding electrode sheet 110 based on a number of AD sampling values, and determine the type of the corresponding electrode sheet 110 based on the code array. As shown in FIG2 , when the electrode sheet 110 has 20 electrode units 112, each electrode unit 112 corresponds to a temperature sensor 114 and a diode 115, that is, the detection positions corresponding to numbers 1 to 20 of the electrode sheet 110 all have a temperature sensor 114, and the codes are all 1, the 20 codes are combined to obtain a 20-bit code array 11111 11111 11111 11111.

[0091] As shown in Figure 8, when the electrode sheet 310 has 13 electrode units 312 and 13 temperature detection units 313, the 13 electrode units 312 and the 13 temperature detection units 313 are arranged in three rows and five columns in the circuit connection, and the 13 electrode units 312 and the 13 temperature detection units 313 are arranged sequentially, and a corresponding position of the 13 temperature detection units 313 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is set at the intersection of the three rows and four columns in the circuit connection to short-circuit the ground terminal 313A of the temperature detection unit 313 in the same group, and at the same time short-circuit the signal terminal 313B of the temperature detection unit 313 in the same column group. Each temperature detection unit 313 includes a temperature sensor 314 and a diode 315, and the corresponding detection positions are numbered 1 to 13, that is, the corresponding detection positions of the electrode sheet 310 numbered 1 to 13 all have temperature sensors 314, and the codes are all 1. Unlike the electrode sheet 110 with 20 electrode units 112, the next detection position (that is, the corresponding detection position number 14) is not provided with an electrode unit 312 (no temperature sensor 314), and is short-circuited in parallel by wires (unnumbered), and the corresponding code is 0; the corresponding detection positions numbered 15 to 20 are not provided with electrode units 312 (no temperature sensor 314), nor are they short-circuited in parallel by wires (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit codes are combined to obtain a 20-bit code array of 11111 11111 11102 22222.

[0092] As shown in Figure 13, when the electrode sheet 710 has 9 electrode units 712 and 9 temperature detection units 713, the 9 electrode units 712 and the 9 temperature detection units 713 are arranged in two rows and five columns in the circuit connection, and the 9 electrode units 712 and the 9 temperature detection units 713 are arranged sequentially, and a corresponding position of the 9 temperature detection units 713 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is set at the intersection of the two rows and five columns in the circuit connection to short-circuit the ground terminal 713A of the temperature detection unit 713 in the same row group, and at the same time short-circuit the signal terminal 713B of the temperature detection unit 713 in the same column group. Each temperature detection unit 713 includes a temperature sensor 714 and a diode 715, and the corresponding detection bits are numbered 1 to 9, that is, the corresponding detection bits of the electrode sheet 710 numbered 1 to 9 all have a temperature sensor 714, and the code is all 1. Unlike the electrode sheet 110 with 20 electrode units 112, the next detection bit (that is, the corresponding detection bit number 10) is not provided with an electrode unit 712 (no temperature sensor 714), and is short-circuited by a wire (unnumbered), and the corresponding code is 0; the corresponding detection bits numbered 11 to 20 are not provided with an electrode unit 712 (no temperature sensor 714), nor are they short-circuited by a wire (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array 11111 11110 22222 22222.

[0093] Among them, the short-circuit wire may not be set in some cases. As shown in Figure 14, when the electrode sheet 810 has 9 electrode units 812 and 9 temperature detection units 813, the 9 electrode units 812 and the 9 temperature detection units 813 are arranged in three rows and three columns in the circuit connection, and the 9 electrode units 812 and the 9 temperature detection units 813 are arranged sequentially, each temperature detection unit 813 includes a temperature sensor 814 and a diode 815, and the corresponding detection bits are numbered 1 to 9, that is, the corresponding detection bits numbered 1 to 9 of the electrode sheet 810 all have a temperature sensor 814, and the codes are all 1; the corresponding detection bits numbered 10 to 20 are not provided with electrode units 812 (no temperature sensor 814), nor are they short-circuited by wires (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array 11111 11112 22222 22222. That is, when the number of electrode units and temperature detection units of the electrode sheet is less than 20, and the last electrode unit is located on the last column group of its circuit, the short-circuit wire can be selectively not provided, and there is no "0" in the coding array.

[0094] When the adapter 120 is not connected to the electrode sheet 110 , the voltage collected by the ADC unit 122 is 3.3V of the DC power supply VCC, so the 20-bit code array obtained is 22222 22222 22222 22222.

[0095] Based on the above rules, it can be seen that: when the electrode sheet with less than 20 electrode units is provided with a corresponding short-circuit wire on the circuit connection, the electrode sheet with 1 electrode unit and 1 temperature detection unit has a corresponding coding array of 10222 22222 22222 22222; the electrode sheet with 2 electrode units and 2 temperature detection units has a corresponding coding array of 11022 22222 22222 22222; the electrode sheet with 3 electrode units and 3 temperature detection units has a corresponding coding array of 11102 22222 22222 22222; the electrode sheet with 4 electrode units and 4 temperature detection units has a corresponding coding array of 11110 22222 22222 22222; the electrode sheet with 5 electrode units and 5 temperature detection units has a corresponding coding array of 11111 02222 22222 22222; for an electrode sheet with 6 electrode units and 6 temperature detection units, the corresponding coding array is 11111 10222 22222 22222; for an electrode sheet with 7 electrode units and 7 temperature detection units, the corresponding coding array is 11111 11022 22222 22222; for an electrode sheet with 8 electrode units and 8 temperature detection units, the corresponding coding array is 11111 11102 22222 22222; for an electrode sheet with 9 electrode units and 9 temperature detection units, the corresponding coding array is 11111 11110 22222 22222; for an electrode sheet with 10 electrode units and 10 temperature detection units, the corresponding coding array is 11111 11111 02222 22222; for an electrode sheet with 11 electrode units and 11 temperature detection units, the corresponding coding array is 11111111111 10222 22222; for an electrode sheet with 12 electrode units and 12 temperature detection units, the corresponding coding array is 11111 11111 11022 22222; for an electrode sheet with 13 electrode units and 13 temperature detection units, the corresponding coding array is 11111 11111 11102 22222; for an electrode sheet with 14 electrode units and 14 temperature detection units, the corresponding coding array is 11111 11111 11110 22222; for an electrode sheet with 15 electrode units and 15 temperature detection units, the corresponding coding array is 11111 11111 11111 02222; for an electrode sheet with 16 electrode units and 16 temperature detection units, the corresponding coding array is 11111 11111 11111 10222; for an electrode sheet with 17 electrode units and 17 temperature detection units, the corresponding coding array is 11111 11111 11111 11022;For an electrode sheet with 18 electrode units and 18 temperature detection units, the corresponding coding array is 11111 11111 11111 11102; for an electrode sheet with 19 electrode units and 19 temperature detection units, the corresponding coding array is 11111 11111 11111 11110; for an electrode sheet with 20 electrode units and 20 temperature detection units, the corresponding coding array is 11111 11111 11111 11111; when the adapter is not connected to the electrode sheet, the corresponding coding array is 22222 22222 22222 22222. The coding array includes at least one of the first coding, the second coding, and the third coding. If some electrode sheets are not provided with a short-circuit wire in the circuit connection, the corresponding second coding "0" of the coding array is replaced by the third coding "2".

[0096] The above multiple numbering arrays are all different, especially the number of first codes included in the numbering arrays is different. Therefore, when the electrode sheet 110 is normal, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the type of electrode sheet 110 connected to the adapter 120 or whether the electrode sheet 110 is connected through the coding array, especially the first code of the coding array.

[0097] When the type of the electrode sheet 110 is determined, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 also determines whether the corresponding electrode sheet 110 has a temperature detection failure based on the coding array, wherein the analog temperature signal detected by each temperature detection unit 113 is also used to characterize whether the electrode sheet 110 has a temperature detection failure.

[0098] As shown in Figure 2, in the electrode sheet 110 having 20 electrode units 112 and 20 temperature detection units 113, in the corresponding electrode sheet 110, it is assumed that the temperature sensor 114 numbered 20 is damaged (open circuit), the AD sampling value obtained by the ADC unit 122 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal coding array is 11111 11111 11111 11112, which is inconsistent with the normal coding array 11111 11111 11111 11111, so the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can distinguish the temperature detection failure.

[0099] In summary, when the temperature sensors 114 of the electrode sheet 110 are all normal, the codes in the corresponding coding array are all "1", that is, the first code. The code "0" in the corresponding 20-bit coding array is not the last digit, and the codes before the code "0" are all "1", and the codes after the code "0" are all "2"; or, the code "0" is the last digit and the codes before the code "0" are all "1"; or, all codes in the 20-bit coding array are "1". When the temperature sensor 114 of the electrode sheet 110 is damaged, regardless of whether the code "0" in the corresponding 20-bit coding array is the last digit, the code before the code "0" is a code different from "1" (code "2"), or all codes in the 20-bit coding array are "1" or "2".

[0100] It should be noted that in the embodiment of the present application, the control switch 124 electrically connected to each of the multiple grounding lines 118 of the electrode sheet 110 and the bidirectional switch 125 electrically connected to each of the multiple dual-purpose signal lines 119 of the electrode sheet 110 are both provided in the adapter 120. However, in other embodiments, the control switch 124 electrically connected to the grounding line 118 and the bidirectional switch 125 electrically connected to the dual-purpose signal line 119 may also be provided on the electrode sheet 110 or provided in the electric field generator 130, which will not be described in detail here. In addition, the ADC unit 122 provided in the adapter 120 may also be provided in the electric field generator 130 and directly controlled by the second controller 131.

[0101] FIG6 is a schematic diagram of a tumor therapy field system 200 according to a second embodiment of the present application. Unlike the tumor therapy field system 100 shown in FIG1-4 , the multiple electrode units 212 of the electrode sheet 210 of this embodiment are spatially connected in a symmetrical manner. For example, the electrode units 212 located in the third column of the first row, the third column of the second row, the third column of the third row, and the third column of the fourth row are connected by a column-oriented connecting strip (unnumbered). Meanwhile, the electrode units 212 located in the fourth column of the first row, the fourth column of the second row, the fourth column of the third row, and the fourth column of the fourth row are connected by a column-oriented connecting strip (unnumbered). As can be seen from the figure, the ten electrode units 212 on the left are symmetrically arranged with the ten electrode units 212 on the right.

[0102] It should be noted that for other relevant descriptions of tumor therapeutic field system 200, please refer to the relevant descriptions of tumor therapeutic field system 100, and the details will not be repeated here.

[0103] Second embodiments:

[0104] Figure 7 is a schematic diagram of a tumor therapy field system 300 according to a third embodiment of the present application. Unlike the tumor therapy field system 100 shown in Figure 1 , the electrode sheet 310 of this embodiment includes 13 electrode units 312 arranged spatially in five rows and five columns. FIG8 is a schematic diagram of the circuit connection between the electrode sheet 310 and the adapter 320 of the tumor electric field therapy system 300 shown in FIG7 . As shown in FIG8 , the 13 electrode units 312 are arranged in three rows and five columns in terms of circuit connection. The first two rows each contain five electrode units 312 , and the third row contains three electrode units 312 . Therefore, only three of the four control switches 324 are connected to the ground wire 318 . The remaining control switch 324 is left floating, and a corresponding position thereof is short-circuited with a wire (unnumbered). Specifically, a wire (unnumbered) is provided at the intersection of the three rows and four columns in terms of circuit connection to short-circuit the ground terminal 313A of the temperature detection unit 313 in the same row group, and simultaneously short-circuit the signal terminal 313B of the temperature detection unit 313 in the same column group.

[0105] FIG9 is a schematic diagram illustrating the circuit connection between the electrode sheet 410 and the adapter 420 according to the fourth embodiment of the present application. Unlike the circuit connection between the electrode sheet 310 and the adapter 320 shown in FIG8 , the 13 electrode units 412 in this embodiment are arranged into four rows and four columns. The first three rows each contain four electrode units 412, and the fourth row contains one electrode unit 412. Consequently, only four of the five bidirectional switches 425 are connected to the dual-purpose signal line 419. The remaining bidirectional switch 425 is left floating, and a corresponding position is shorted to a wire (unnumbered). Specifically, a wire (unnumbered) is provided at the intersection of the four rows and two columns, shorting the ground terminal 413A of the temperature detection unit 413 in the same row group and the signal terminal 413B of the temperature detection unit 413 in the same column group.

[0106] Figure 10 is a schematic diagram of a tumor therapeutic field system 500 according to the fifth embodiment of the present application, and Figure 11 is a schematic diagram of a tumor therapeutic field system 600 according to the sixth embodiment of the present application. Unlike the tumor therapeutic field system 300 shown in Figure 7 , the spatial structure of the system differs in that the connecting strips (unnumbered) are arranged differently, forming corresponding open spaces (unnumbered) or intervals (unnumbered) to accommodate different application methods, such as horizontal or vertical application, and to prevent the electrode sheets from tilting during application.

[0107] It should be noted that, for descriptions of other relevant contents of the second embodiments, please refer to the relevant descriptions of the first embodiments, and the details will not be repeated here.

[0108] The third embodiment:

[0109] Figure 12 is a schematic diagram of a seventh embodiment of a tumor therapy field system 700 of the present application. Unlike the tumor therapy field system 100 shown in Figure 1 , the electrode sheet 710 of this embodiment has nine electrode units 712 arranged spatially in three rows and three columns. FIG13 is a schematic diagram of the circuit connection between the electrode sheet 710 and the adapter 720 of the tumor electric field therapy system 700 shown in FIG12 . As shown in FIG13 , the nine electrode units 712 are configured in two rows and five columns in terms of circuit connection, wherein the first row group each includes five electrode units 712 and the second row group includes four electrode units 712. Therefore, only two of the four control switches 724 are connected to the ground wire 718, while the other two control switches 724 are left floating and short-circuited with a wire (unnumbered) at a corresponding position thereof. That is, in terms of circuit connection, a wire (unnumbered) is provided at the intersection of the two row groups and the five column groups to short-circuit the ground terminal 713A of the temperature detection unit 713 in the same row group and simultaneously short-circuit the signal terminal 713B of the temperature detection unit 713 in the same column group.

[0110] FIG14 is a schematic diagram illustrating the circuit connection between an electrode sheet 810 and an adapter 820 according to an eighth embodiment of the present application. Unlike the circuit connection between the electrode sheet 710 and the adapter 720 shown in FIG13 , the nine electrode units 812 in this embodiment are arranged into three rows and three columns, with each row group containing three electrode units 812. Consequently, only three of the four control switches 824 are connected to a ground line 818, leaving one control switch 824 floating. Furthermore, only three of the five bidirectional switches 825 are connected to a dual-purpose signal line 819, leaving the other two bidirectional switches 825 floating.

[0111] It should be noted that, for descriptions of other relevant contents of the third embodiments, please refer to the relevant descriptions of the first embodiments, and the details will not be repeated here.

[0112] The flexible circuit board of the electrode sheet of the present application electrically connects the signal end of the same electrode unit and the corresponding temperature detection unit simultaneously through the same dual-purpose signal line. While realizing that the dual-purpose signal line can transmit both an alternating electrical signal and a direct current signal for temperature signal acquisition and the acquired temperature detection signal, it also greatly reduces the number of conductive traces (grounding wire, dual-purpose signal line) arranged thereon, thereby reducing the wiring difficulty of the flexible circuit board, simplifying the manufacturing process, reducing the weight of the flexible circuit board, and reducing the manufacturing cost. At the same time, the temperature of all electrode units on the electrode sheet can be monitored in real time and comprehensively without increasing the weight of the electrode sheet or the core of the first cable electrically connected to the electrode sheet. If the electrode sheet is qualified, the type of the electrode sheet can be identified based on the obtained temperature detection signal, thereby automatically identifying the type of the electrode sheet and realizing temperature acquisition of different types of electrode sheets without missing any acquisition or generating interference signals. When the type of the electrode sheet is determined, the analog temperature signal detected by each temperature detection unit sampled is also used to indicate whether the electrode sheet has a temperature detection failure, thereby identifying abnormal temperature detection units.

[0113] In summary, in all the above embodiments, the number of control switches provided on the adapter corresponding to each electrode sheet is fixed at four, and the number of bidirectional switching switches provided on each electrode sheet is also fixed at five, corresponding to the five detection channels A, B, C, D, and E of the ADC unit, respectively. When the number of rows in which the electrode units on the electrode sheet are arranged on the circuit is less than four, that is, the number of grounding wires connected one-to-one between the electrode sheet and the control switch is less than four, some of the control switches will be suspended, and the subsequent positions will be short-circuited with a wire (unnumbered), which is short-circuited with the ground terminal of the temperature detection unit in the same group and short-circuited with the signal terminal of the temperature detection unit in the same column group, as shown in FIG8 . Similarly, when the number of columns in which the electrode units on the electrode sheet are arranged on the circuit is less than five, that is, the number of dual-purpose signal lines connected one-to-one with the bidirectional switching switches on the electrode sheet is less than five, some of the bidirectional switching switches will be suspended, and the subsequent positions will be short-circuited with a wire (unnumbered) in the same manner, as shown in FIG9 . Similarly, when there are fewer than four ground lines and fewer than five dual-purpose signal lines on the electrode sheet, some control switches will be suspended, and some bidirectional switches will be suspended, as shown in Figure 14. The shorting wire (unnumbered) is optional. When the last electrode unit is not in the last column group on the circuit, a wire is shorted at the position following the last electrode unit. This wire is shorted to the ground terminal of the temperature detection unit in the same column group and is also shorted to the signal terminal of the temperature detection unit in the same column group. When the last electrode unit is in the last column group on the circuit, the shorting wire can be removed, as shown in Figure 14.

[0114] Fourth embodiment:

[0115] The present application also provides some other different embodiments. Different from the aforementioned embodiments, the number of control switches and the number of bidirectional switching switches on the adapter are not fixed, but are set according to needs. The suspended control switches and bidirectional switching switches are eliminated, and the short-circuit wires are also eliminated.

[0116] Referring to Figures 15 and 16, Figure 15 shows a schematic diagram of the circuit connection between an electrode sheet 910 and an adapter 920 according to the ninth embodiment of the present application, and Figure 16 shows a schematic diagram of the internal structure of the adapter 920 according to the ninth embodiment of the present application. The electrode sheet 910 is provided with 20 electrode units, each electrode unit 912 is provided with a temperature detection unit 913, and these 20 electrode units 912 are arranged in five rows and four columns in terms of circuit connection, wherein each row group contains four electrode units 912. The adapter 920 is provided with five control switches 924 for respectively connecting the five ground lines 918 of the electrode sheet 910; and four bidirectional switches 925 for respectively connecting the four dual-purpose signal lines 919 of the electrode sheet 910.

[0117] Referring to Figures 17 and 18 , Figure 17 shows a schematic diagram of the circuit connection between the electrode sheet 1010 and the adapter 1020 according to the tenth embodiment of the present application, and Figure 18 shows a schematic diagram of the internal structure of the adapter 1020 according to the tenth embodiment of the present application. The electrode sheet 1010 is provided with 13 electrode units 1012, each of which is provided with a temperature detection unit 1013. The 13 electrode units 1012 are arranged in three rows and five columns in terms of circuit connection. The electrode sheet 1010 is provided with three ground wires 1018. The adapter 1020 is provided with three control switches 1024 for connecting the three ground wires 1018 of the electrode sheet 1010, and five bidirectional switches 1025 for connecting the five dual-purpose signal wires 1019 of the electrode sheet 1010. There are no suspended control switches 1024 and no short-circuited wires.

[0118] It is understandable that in each embodiment, the specific number of electrode units in each row and column can be adjusted as needed. For example, an electrode sheet with 13 electrode units can also be arranged as three rows and five columns on the circuit, with four in each of the first two rows and five in the third row, that is, the electrode sheet is provided with three grounding wires and five dual-purpose signal lines, and the corresponding adapter is provided with three control switches and five bidirectional switching switches. An electrode sheet with 13 electrode units can also be configured as a four-row group and a four-column group in terms of circuit connection, with four in each of the first three rows and one in the fourth row, or three in each of the first three rows and four in the fourth row, that is, the electrode sheet is provided with four grounding wires and four dual-purpose signal lines, and the corresponding adapter is provided with four control switches and four bidirectional switching switches, without a suspended bidirectional control switch and without a short-circuited wire.

[0119] Referring to Figures 19 and 20, Figure 19 shows a schematic diagram of the circuit connection between the electrode sheet 1110 and the adapter 1120 according to the eleventh embodiment of the present application, and Figure 20 shows a schematic diagram of the internal structure of the adapter 1120 according to the eleventh embodiment of the present application. The electrode sheet 1110 is provided with nine electrode units 1112, each of which is provided with a temperature detection unit 1113. These nine electrode units 1112 are arranged in three rows and three columns in terms of circuit connection. The electrode sheet 1110 is provided with three ground wires 1118 and three dual-purpose signal wires 1119. The adapter 1120 is provided with three control switches 1124 and three bidirectional switches 1125. There are no suspended control switches 1124, no suspended bidirectional switches 1125, and no short-circuited wires.

[0120] The electrode sheet with 9 electrode units can also be configured into two rows and five columns in terms of circuit connection, with 5 in the first row and 4 in the second row, that is, the electrode sheet is provided with 2 grounding wires and 5 dual-purpose signal lines, and the corresponding adapter is provided with 2 control switches and 5 bidirectional switching switches. There are no suspended bidirectional control switches and no short-circuited wires.

[0121] As mentioned in the first embodiments, the ADC unit samples and encodes the temperature sensors of each electrode. In the first through third embodiments, the number of control switches in the adapter is fixed at four, and the number of bidirectional switches is fixed at five, thus forming 20 detection bits. The ADC unit obtains 20 AD sample values ​​each time it acquires data. After each acquisition, a 20-bit encoding array is formed based on the 20 AD sample values.

[0122] However, in some fourth embodiments, the number of control switches and bidirectional switches in the adapter is set as needed rather than fixed, and there are no short-circuited wires. The number of AD sampling values ​​collected by the ADC unit, i.e., the number of detection bits, is not fixed to 20, and the number of bits in the encoding array is not fixed to 20, but is consistent with the number of electrode units in the electrode sheet. For example, the electrode sheet 910 shown in FIG15 has 20 electrode units 912, and the detection bits of the electrode sheet 910 are numbered 1 to 20. That is, the detection bits corresponding to the numbers 1 to 20 of the electrode sheet 910 all have a temperature sensor 914, and the code is all 1. Therefore, by combining the 20-bit code, the resulting 20-bit standard code array is 1111 1111 1111 1111 1111. The electrode sheet 1010 shown in FIG17 has 13 electrode units 1012. The detection bits of the electrode sheet 1010 are numbered 1 to 13, that is, the detection bits corresponding to the numbers 1 to 13 of the electrode sheet 1010 all have a temperature sensor 1014, and the codes are all 1. Therefore, by combining the 13-bit codes, the 13-bit code array obtained is 11111 11111 111. The electrode sheet 1110 shown in FIG19 has 9 electrode units 1112. The detection bits corresponding to the electrode sheet 1110 are numbered 1 to 9. That is, the detection bits corresponding to the numbers 1 to 9 of the electrode sheet 1110 all have a temperature sensor 1114, and the codes are all 1. Therefore, by combining the 9-bit codes, the 9-bit code array obtained is 11111 1111.

[0123] Based on the above rules, it can be known that: when the electrode sheet is not provided with a corresponding short-circuit wire on the circuit connection, the number of bits of the coding array corresponding to the electrode sheet in the fourth embodiment is the same as the number of its electrode units, and all are first codes. The coding array corresponding to the electrode sheet with 20 electrode units is 11111 11111 11111 11111, the coding array corresponding to the electrode sheet with 13 electrode units is 11111 11111 111, the coding array corresponding to the electrode sheet with 9 electrode units is 11111 1111, and the coding array corresponding to the electrode sheet with 1 electrode unit is 1. Therefore, the first controller of the adapter or the second controller of the electric field generator can determine the type of electrode sheet connected to the adapter through the coding array when the electrode sheet is normal.

[0124] When the type of electrode sheet is determined, it is determined whether the corresponding electrode sheet has a temperature detection fault based on the coding array. As shown in Figure 15, in an electrode sheet 910 with 20 electrode units 912, it is assumed that the temperature sensor 914 numbered 20 is damaged (open circuit), the AD sampling value obtained by the ADC unit 122 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal coding array is 11111 11111 11111 11112. This coding array is inconsistent with the normal coding array 11111 11111 11111 11111, and it can be determined that a temperature detection fault has occurred.

[0125] In summary, when the temperature sensors 114 of the electrode sheets 110 are all normal, the codes in the corresponding coding arrays are all “1”, ie, the first code.

[0126] 21 , the present application also provides a method for identifying electrode sheet types, which includes the following steps:

[0127] S110: Determine the temperature detection signal of each electrode unit in each electrode sheet.

[0129] S120: Determine a coding array of a corresponding electrode sheet according to the temperature detection signal, where the coding array includes a first code for indicating that the temperature detection unit is in a normal state.

[0130] S130: Determine the type of the corresponding electrode sheet based on the first code in the code array.

[0131] Specifically, when the electrode sheet 110 is qualified or there is no abnormality or failure in each temperature detection unit 113 of the electrode sheet 110, the coding array of the corresponding electrode sheet 110 is determined based on the temperature detection signal detected by the temperature detection unit 113 of each electrode unit 112 in the electrode sheet 110, and then the type of the corresponding electrode sheet 110 is determined based on the first code in the coding array.

The point (unnumbered) samples the analog temperature signal detected by the corresponding temperature detection unit 113 (or 313, etc.) in each row group, and determines the coding array of the corresponding electrode sheet 110 (or 310, etc.) based on the sampled analog temperature signal detected by each temperature detection unit 113 (or 313, etc.), the coding array includes a first code for indicating that the temperature detection unit 113 (or 313, etc.) is in a normal state, and determines the type of the corresponding electrode sheet 110 (or 310, etc.) through the first code in the coding array, or controls the electrode unit 112 (or 312, etc.) of at least one column group to be applied with an alternating electrical signal based on the alternating power line 127 (or 327, etc.).
