Description

[0001] This application is a divisional application of the invention patent application with the application date of December 30, 2022, application number 202211721864.3, and invention name "Tumor electric field therapy system, tumor treatment equipment and electrode temperature detection method". Technical Field

[0002] The present invention relates to the technical field of medical devices, and in particular to a tumor electric field therapy system, tumor therapy equipment, and an electrode temperature detection method. Background Art

[0003] Tumor Treating Fields (TTF) is a tumor therapy that uses an electric field generator to generate a low-intensity, medium-to-high-frequency, alternating electric field to disrupt the mitotic process of tumor cells. The applied electric field can affect the aggregation of microtubules, preventing spindle formation, inhibiting mitosis, and inducing apoptosis in cancer cells.

[0004] At present, 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 electrodes electrically connected to the electric field generator through the adapter. The electric field generator transmits the alternating electric signal for tumor electric field therapy to each electrode through the adapter, and then applies an alternating electric field to the patient's tumor site through the electrode to perform tumor electric field therapy. Among them, when the electric field is applied to the patient's body, heat will accumulate at the corresponding position where the electrode is attached to the skin. Therefore, it is necessary to monitor the temperature of the body surface corresponding to the patient's tumor site where the electrode is attached in real time. When the body surface temperature is too high, it is necessary to adjust the intensity of the alternating electric field in time to avoid excessive temperature causing low-temperature burns on the patient's skin.

[0005] In the related art, an electrode sheet is provided with a thermistor element on each of its corresponding electrode units, and multiple thermistor elements are connected in parallel to each other, and the temperature change of the corresponding electrode unit is monitored in real time by the change in the resistance of the thermistor element. For example, in an electrode sheet with 9 electrode units, 8 thermistor elements are provided, and the resistance of the 8 thermistor elements is transmitted through a 10-core cable. The 10-core cable includes 1 AC signal line (AC line), 1 ground line, and 8 signal lines. The coverage rate of the thermistor elements in the electrode sheet is about 89% (8 / 9≈0.89). When the number of electrode units increases, if the number of thermistor elements remains unchanged, it is easy for the patient's skin to be burned by low temperature. For example, in an electrode sheet with 20 electrode units, 8 thermistor elements are provided. The coverage rate of the thermistor elements in the electrode sheet is about 40% (8 / 20=0.4), that is, the temperature of more than half of the electrode units cannot be monitored, which is easy to cause the patient's skin to be burned by low temperature. If a thermistor element is set on each electrode unit to maintain the coverage of the thermistor element, then a cable with more cores will be needed. However, this will cause the cable to become thicker and harder, increasing the difficulty of fixing the cable. At the same time, the overall weight of the electrode sheet will increase due to the increase in cable cores, which will not only affect the adhesion effect between the electrode sheet and the patient's body surface corresponding to the tumor site, but also increase the patient's weight and cause discomfort. Summary of the Invention

[0006] The present invention aims to at least partially address one of the technical problems in the related art. To this end, a first object of the present invention is to provide a tumor electric field therapy system that not only achieves 100% temperature sensor coverage without increasing the number of cable cores, thereby preventing excessive weight on the electrode sheet and maintaining the electrode sheet's application effect, but also, by screening the switch combinations of the first switch and the second switch and performing temperature detection based on the screened switch combinations, can improve the temperature detection speed and reduce resource usage while ensuring that each temperature sensor is detected.

DETAILED DESCRIPTION

[0053] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0054] refer to Figures 1 to 3 As shown, the tumor electric field treatment system 1000 includes: at least one pair of electrode sheets 100, an adapter 120 electrically connected to each electrode sheet 100, and an electric field generator 130 electrically connected to the adapter 120. At least one pair of electrode sheets can be arranged in pairs on the patient's body surface, such as Figure 1The four electrode sheets X1, Y1, X2 and Y2 in the apparatus are applied as a pair of two electrode sheets to the body surface corresponding to the tumor site of the patient. The electric field generator 130 is used to generate an alternating electric signal, and switch the alternating electric signal to at least one pair of electrode sheets 100 through the adapter 120. Each pair of electrode sheets 100 applies the alternating electric signal to the tumor site of the patient, so that a therapeutic alternating electric field (i.e., a tumor treatment electric field) is generated between the same pair of electrode sheets 100, and acts on the tumor site of the patient to treat the tumor. The alternating electric signals applied by the two electrode sheets 100 in the same pair of electrode sheets 100 are different. The two electrode sheets 100 respectively apply a set of alternating electric signals with opposite polarities, and generate an alternating electric field in one direction between the two electrode sheets 100. Alternating electric fields in different directions are generated between different pairs of electrode sheets 100.

[0055] refer to Figure 2 As shown, each electrode sheet includes a substrate 111, a plurality of electrode elements 112 and a plurality of temperature sensors 113 disposed on the substrate 111. Figure 1 As shown, multiple electrode elements 112 are arranged roughly in an array, and each electrode element 112 can apply an alternating electric field. Multiple electrode elements 112 of the same electrode sheet 100 all apply the same alternating electric signal. Each temperature sensor 113 is arranged corresponding to an electrode element 112, and the number of temperature sensors 113 is equal to the number of electrode elements 112, that is, the coverage rate of temperature sensors 113 on the electrode sheet 100 reaches 100%. In this embodiment, each electrode sheet 100 includes 13 electrode elements 112, and each electrode element 112 is correspondingly provided with a temperature sensor 113, and the temperature at the corresponding electrode element 112 is detected by the temperature sensor 113.

[0056] Each electrode element 112 is provided with a through hole 116, and the through hole 116 is suitable for accommodating a corresponding temperature sensor 113, thereby realizing real-time monitoring of the temperature of each electrode element 112, and avoiding the temperature of some electrode elements 112 not being monitored, resulting in excessively high temperature on the patient's body surface and causing low-temperature burns to the patient. Figure 2 As shown, the through hole 116 of each electrode element 112 is located in the middle thereof. In this embodiment, the electrode element 112 is a dielectric element, and preferably, the electrode element 112 is a ceramic sheet.

[0057] like Figure 2As shown, the multiple electrode elements 112 and the corresponding multiple temperature sensors 113 are configured into at least three row groups and at least three column groups in terms of circuit connection structure. The number of electrode elements 112 and temperature sensors 113 located in the same row group is not exactly the same, and the number of electrode elements 112 and temperature sensors 113 located in the same column group is not exactly the same. The multiple electrode elements 112 of each row group are connected in parallel to the same circuit, and the parallel circuits of the multiple electrode elements 112 of each row group are cascaded into one circuit, which is an AC signal line (AC line) for transmitting AC signals to the multiple electrode elements 112. It should be noted that the arrangement here is to more clearly show the interior of the electrode sheet 100 and the electrical connection between the electrode sheet 100 and the adapter 120, and does not represent the arrangement of the electrode elements 112 in the spatial structure. Its spatial structure may be as follows Figure 1 The structure shown is roughly an array.

[0058] Each temperature sensor 113 has a signal terminal 113A and a ground terminal 113B. Multiple temperature sensors 113 in the same row group are connected in series. A signal terminal 113A at the end of each row group is connected to the DC power supply VCC via a first switch and a voltage divider resistor connected in series. The ground terminals 113B of the corresponding temperature sensors 113 in each column group are connected together and then connected to the ground pin GND via a second switch. The total number of first and second switches does not exceed nine. The tumor therapy field system 1000 configures the switching sequence of the first and second switches to sample the analog temperature signals detected by one or more corresponding combinations of all temperature sensors 113 in the electrode sheet 100.

[0059] In this embodiment, Figure 2 As shown in FIG, in terms of the circuit connection structure, the 13 electrode elements 112 are arranged into 3 row groups and 5 column groups, wherein the first and second row groups each have 5 electrode elements 112, the third row group has 3 electrode elements 112, and the first to third column groups each have 3 electrode elements 112, and the fourth and fifth column groups each have 2 electrode elements 112, that is, the 13 electrode elements 112 are arranged in three rows and five columns. Figure 2As shown, all temperature sensors 113 in the same row group are connected in series to form a line (e.g., one of lines A, B, or C) connected to the DC power supply VCC. The ground terminals 113B of all temperature sensors 113 in the same row group are connected to the ground pin GND via five ground lines (e.g., ground lines D, E, F, G, and H). The ground terminals 113B of all temperature sensors 113 in the same column group are connected to the same ground line (e.g., one of ground lines D, E, F, G, and H). Each row group of temperature sensors 113 connected in series has a first switch (e.g., first switch K1, K2, or K3) and a voltage divider resistor (e.g., voltage divider resistor R1, R2, or R3) connected in series to the DC power supply VCC. The voltage divider resistor (e.g., voltage divider resistor R1, R2, or R3) is closer to the DC power supply VCC than the first switch (e.g., first switch K1, K2, or K3). Each ground line is connected in series to a second switch (e.g., second switch K5, K6, K7, K8, or K9). It should be noted that there is no limitation on the types of the first switch and the second switch, and they may be normally open switches or normally closed switches, for example.

[0060] Specifically, the five temperature sensors 113 (corresponding to serial numbers 1, 2, 3, 4, and 5) in the first row group are connected end to end in series to form a line A connected to the DC power supply VCC, and connected to the first switch K1 and the voltage divider resistor R1.

The ground terminal 113B of the fourth temperature sensor 113 (corresponding number 9) is connected to the ground line G and the second switch K8. The ground terminal 113B of the fifth temperature sensor 113 (corresponding number 10) is connected to the ground line H and the second switch K9.

[0062] The three temperature sensors 113 (corresponding serial numbers 11, 12, and 13) in the third row group are connected end to end in series to form a line C connected to the DC power supply VCC, and connected to the first switch K3 and the voltage divider resistor R3. The ground terminal 113B of the first temperature sensor 113 (corresponding serial number 11) in the third row group is connected to the ground line D and the second switch K5. The ground terminal 113B of the second temperature sensor 113 (corresponding serial number 12) is connected to the ground line E and the second switch K6. The ground terminal 113B of the third temperature sensor 113 (corresponding serial number 13) is connected to the ground line F and the second switch K7.

[0063] Each electrode sheet 100 further includes a plurality of diodes 114, each diode 114 being provided corresponding to a temperature sensor 113. The diode 114 has an anode 114A and a cathode 114B. The ground terminal 113B of the corresponding temperature sensor 113 in each column group is connected to the anode 114A of the corresponding diode 114, and then connected together through the cathode 114B of the corresponding diode 114. Figure 2As shown, the ground terminal 113B of each temperature sensor 113 of the first column group (corresponding to serial numbers 1, 6, and 11) is respectively connected to a diode 114, and the anode 114A of the diode 114 in the first column group is connected to the ground terminal 113B of the corresponding temperature sensor 113, and the cathode 114B of each diode 114 in the first column group is connected to the ground line D; the ground terminal 113B of each temperature sensor 113 of the second column group (corresponding to serial numbers 2, 7, and 12) is respectively connected to a diode 114, and the anode 114A of the diode 114 in the second column group is connected to the ground terminal 113B of the corresponding temperature sensor 113, and the cathode 114B of each diode 114 in the second column group is connected to the ground line E; the ground terminal 113B of each temperature sensor 113 of the third column group (corresponding to serial numbers 3, 8, and 13) is respectively connected to a diode 114, and the anode 114A of the diode 114 in the third column group is connected to the ground line E.

The ground terminal 113B of each temperature sensor 113 in the fourth column group (corresponding to serial numbers 4 and 9) is respectively connected to a corresponding diode 114, and the anode 114A of the diode 114 in the fourth column group is connected to the ground terminal 113B of the corresponding temperature sensor 113, and the cathode 114B of each diode 114 in the fourth column group is respectively connected to the ground line G. The ground terminal 113B of each temperature sensor 113 in the fifth column group (corresponding to serial numbers 5 and 10) is respectively connected to a corresponding diode 114, and the anode 114A of the diode 114 in the fifth column group is connected to the ground terminal 113B of the corresponding temperature sensor 113, and the cathode 114B of each diode 114 in the fifth column group is connected to the ground line H. That is, a diode 114 is connected between the ground terminal 113B and the ground pin GND of all temperature sensors 113 located in the same column group. The diode 114 can effectively prevent other temperature sensors 113 from affecting the resistance value of the corresponding temperature sensor 113 detected by the switching timing control of the first switch and the second switch.

[0064] like Figure 1-Figure 3 As shown, a first connector 140 is connected between each electrode sheet and the adapter 120. The first connector 140 is suitable for connecting the corresponding electrode sheet to the adapter 120. Each electrode sheet 100 has a first cable 115 electrically connected to its substrate 111. The first connector 140 includes a first plug 141 provided at an end of the first cable 115 away from the substrate 111 and a first socket 142 provided on the adapter 120. The first plug 141 and the first socket 142 are press-type spring connectors, that is, the first connector 140 uses a connector to connect the adapter 120 to the electrode sheet 100.

[0065] like Figure 1 As shown, the four electrode sheets X1, Y1, X2 and Y2 are connected to the adapter 120 through a first connector 140, wherein the electrode sheets X1 and X2 are configured as a pair of electrode sheets 100, and the electrode sheets Y1 and Y2 are configured as another pair of electrode sheets 100. Figure 3 As shown, each first connector 140 is connected to Figure 3 A corresponding line among lines a1, a2, a3, and a4 transmits an alternating electrical signal of a corresponding direction and polarity, thereby generating a therapeutic electric field for treating tumors between a corresponding pair of electrode sheets 100 (e.g., electrode sheets X1 and X2 or electrode sheets Y1 and Y2). It can be understood that lines a1, a2, a3, and a4 are AC lines that transmit alternating electrical signals of corresponding directions and polarities, and extend into a corresponding electrode sheet 100 to provide corresponding alternating electrical signals to the multiple electrode elements 112 of the electrode sheet 100. Lines a1, a2, a3, and a4 are connected to a second connector 150 in a direction away from the first connector 140, and the second connector 150 is connected to the electric field generator 130. The electric field generator 130 is powered by a DC power supply, which converts the DC power supply through inversion and filtering to generate two sets of switched alternating electrical signals, each set of alternating electrical signals consisting of two alternating electrical signals with opposite polarities. The two sets of alternating electric signals generated by the electric field generator 130 are respectively transmitted to the multiple electrode elements 112 of the corresponding electrode sheet 100 through the second connector 150, a corresponding line among the lines a1, a2, a3, and a4, and the corresponding first connector 140. In addition, the electric field generator 130 also transmits the DC power supply through the second connector 150, the power line and ground line of the DC power supply VCC inside the adapter 120, and the corresponding first connector 140 to the multiple temperature sensors 113 of the corresponding electrode sheet 100, so that the corresponding temperature sensor 113 works and generates an analog temperature signal. Figure 3 In the example shown, an inverter 126 is further provided between lines a1, a2, a3 and a4, wherein lines a1 and a3 are connected to one end of the inverter 126, and lines a2 and a4 are connected to the other end of the inverter 126, so as to realize the alternating application of alternating electrical signals to the two pairs of electrode sheets 100 through the inverter 126.

[0066] like Figure 2-Figure 3 As shown, each first connector 140 is also connected to a set of multi-line temperature switching acquisition lines a5, a6, a7 or a8, wherein each temperature switching acquisition line includes: four lines connected to the first switches K1, K2, K3 and K4 respectively, and five ground lines connected to the second switches K5, K6, K7, K8 and K9 respectively. In this embodiment, referring to Figure 2In this example, the first switch K4 is not connected to any temperature sensor 113. As a preset switch, it can adapt to the connection of other types of electrode sheets 100. For example, it can adapt to electrode sheets 100 with 13 or other numbers of electrode elements 112 including other circuit connection designs. In this way, an adapter 120 with a substantially similar configuration can be used to connect to different types of electrode sheets 100, thereby improving the applicability of the adapter 120. The first switch K4 can be disconnected from the first connector 140, in which case the number of wire cores of the first cable 115 of the electrode sheet 100 connected to the first connector 140 can be reduced. The first switch K4 can also be connected to the first socket 142 of the first connector 140, resulting in one less wire core of the first cable 115 on the corresponding electrode sheet 100, with only the corresponding first plug 141 connected to the first socket 142, thereby reducing the number of wire cores of the first cable 115 of the electrode sheet 100.

[0067] Combine Figures 1 to 3 As shown, when the first switch K4 is disconnected or connected to the first connector 140, the first cable 115 of the electrode sheet X1 is connected to the first connector 140 for 9 lines. Similarly, the first cable 115 of the electrode sheet Y1 is connected to the first connector 140 for 9 lines, the first cable 115 of the electrode sheet X2 is connected to the first connector 140 for 9 lines, and the first cable 115 of the electrode sheet Y2 is connected to the first connector 140 for 9 lines. Accordingly, as shown in FIG. Figure 1-Figure 2 As shown, the first cable 115 between each electrode sheet 100 and the corresponding first connector 140 is a 9-core cable.

[0068] like Figure 2-Figure 3As shown, a plurality of first switches (K1, K2, K3, and K4) and a plurality of second switches (K5, K6, K7, K8, and K9) constitute a temperature detection switch unit 121, and the temperature detection switch unit 121 and the voltage divider resistors (such as voltage divider resistors R1-R4, R5-R8, R9-R12, or R13-R16) connected to the first switch in each temperature detection switch unit 121 are all located in the adapter 120. The adapter 120 includes the aforementioned plurality of temperature detection switch units 121, the voltage divider resistors (such as voltage divider resistors R1-R4, R5-R8, R9-R12, or R13-R16), and also includes an ADC sampling unit 122 for collecting analog temperature signals from the corresponding temperature sensors 113, and a controller 123 for controlling the timing on and off of the plurality of first switches and the plurality of second switches in the corresponding temperature detection switch unit 121. The controller 123 is configured to control the first and second switches in combination so that the ADC sampling unit 122 acquires an analog signal corresponding to each of all combinations. The controller 123 is further configured to determine a combination having an analog temperature signal based on the analog signal, and to control the first and second switches based on the combination having the analog temperature signal so that the ADC sampling unit 122 samples the analog temperature signal detected by each temperature sensor 113 in the electrode sheet. The controller 123 then computationally converts the analog temperature signal collected by the ADC sampling unit 122 into a digital temperature signal. When the analog signal is within a preset signal range, the analog signal is determined to be an analog temperature signal, and the combination corresponding to the analog temperature signal is the combination used for temperature detection.

[0069] like Figure 3 As shown, the multiple temperature detection switch units 121 in the adapter 120 transmit the analog temperature signal to the corresponding channel of the ADC sampling unit 122 through a group of line groups (one group among a9, a10, a11 and a12). Figure 2 and Figure 3As shown, in this embodiment, the four temperature detection switch units 121 transmit the analog temperature signal to the corresponding channel of the ADC sampling unit 122 through a group of line groups (one group among a9, a10, a11 and a12). The temperature detection switch unit 121 corresponding to the electrode sheet X1 transmits the analog temperature signal generated by the temperature sensor 113 of the electrode sheet X1 to channels 1-4 of the ADC sampling unit 122 through the 4-line group a9; the temperature detection switch unit 121 corresponding to the electrode sheet Y1 transmits the analog temperature signal generated by the temperature sensor 113 of the electrode sheet Y1 to channels 5-8 of the ADC sampling unit 122 through the 4-line group a10; the temperature detection switch unit 121 corresponding to the electrode sheet X2 transmits the analog temperature signal generated by the temperature sensor 113 of the electrode sheet X2 to channels 9-12 of the ADC sampling unit 122 through the 4-line group a11; the temperature detection switch unit 121 corresponding to the electrode sheet Y2 transmits the analog temperature signal generated by the temperature sensor 113 of the electrode sheet Y2 to channels 13-16 of the ADC sampling unit 122 through the 4-line group a12. The controller 123 controls the opening and closing of the plurality of first switches and the plurality of second switches in the corresponding temperature detection switch unit 121, and closes a first switch (e.g., one of K1, K2, K3, and K4) and a second switch (e.g., one of K5, K6, K7, K8, and K9) to cause the corresponding temperature sensor 113 to generate an analog temperature signal. The ADC sampling unit 122 collects the analog temperature signal and transmits it to the corresponding channel of the ADC sampling unit 122 via a line connected to the closed first switch. That is, when the ADC sampling unit 122 collects the analog temperature signal from the corresponding temperature sensor 113 on each electrode sheet 100, it transmits it to its corresponding channel via a line connected to the closed first switch in the corresponding line group (one of a9, a10, a11, and a12).

[0070] The controller 123 controls the on and off of the plurality of first switches and the plurality of second switches in each temperature detection switch unit 121, and closes a first switch (e.g., one of K1, K2, K3, and K4) and a second switch (e.g., one of K5, K6, K7, K8, and K9) to sequentially obtain the analog temperature signals generated by the corresponding temperature sensors 113 in the electrode sheet 100. In this embodiment, as Figure 2As shown, when the controller 123 controls the first switch K1 and the second switch K5 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first temperature sensor 113 (corresponding to serial number 1) of the first row group; when the controller 123 controls the first switch K1 and the second switch K6 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first to second temperature sensors 113 (corresponding to serial numbers 1 and 2) of the first row group; when the controller 123 controls the first switch K1 and the second switch K7 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first row group. The analog temperature signals of the first to third temperature sensors 113 (corresponding to numbers 1, 2, and 3) in the first row group are combined. When the controller 123 controls the first switch K1 and the second switch K8 to be turned on and the other switches to be turned off, the ADC sampling unit 122 samples the analog temperature signals of the first to fourth temperature sensors 113 (corresponding to numbers 1, 2, 3, and 4) in the first row group. When the controller 123 controls the first switch K1 and the second switch K9 to be turned on and the other switches to be turned off, the ADC sampling unit 122 samples the analog temperature signals of the first to fifth temperature sensors 113 (corresponding to numbers 1, 2, 3, 4, and 5) in the first row group. Similarly, the analog temperature signals generated by the temperature sensors 113 in the other row groups can be obtained.

[0071] like Figure 2-Figure 3 As shown, the adapter 120 further includes a serial communication unit 124, which transmits the digital temperature signal converted by the controller 123 to the electric field generator 130. The serial communication unit 124 is controlled by the controller 123, and the digital temperature signal converted by the controller 123 is serially transmitted through the serial communication unit 124 to transmit the digital temperature signal of each temperature sensor 113 to the electric field generator 130.

[0072] In this embodiment, Figure 2As shown, there are four first switches (e.g., K1, K2, K3, and K4) and five second switches (e.g., K5, K6, K7, K8, and K9). One first switch (e.g., K1, K2, K3, and K4) and one second switch (e.g., K5, K6, K7, K8, and K9) are turned on, and the rest of the switches are turned off. In this way, 20 combinations can be obtained, namely: K1K5, K1K6, K1K7, K1K8, K1K9, K2K5, K2K6, K2K7, K2K8, K2K9, K3K5, K3K6, K3K7, K3K8, K3K9, K4K5, K4K6, K4K7, K4K8, and K4K9. Before performing temperature detection, the controller 123 can first predict the analog temperature signal based on these combinations. At this time, the controller 123 sequentially turns on the first switch (for example, one of K1, K2, K3 and K4) and the second switch (for example, one of K5, K6, K7, K8 and K9) in these combinations, and collects the analog signal corresponding to each combination through the ADC acquisition unit 122. Among these analog signals, some are analog temperature signals and some are 0 values or full-scale values. For example, in the aforementioned 20 combinations, K1K5, K1K6, K1K7, K1K8, K1K9, K2K5, K2K6, K2K7, K2K8, K2K9, K3K5, K3K6, K3K7 have analog temperature signals, while the analog signals of K3K8, K3K9, K4K5, K4K6, K4K7, K4K8, K4K9 are full-scale values. Therefore, based on the analog signal, a combination with an analog temperature signal can be screened out, and then the combination with the analog temperature signal is stored as a combination for temperature detection. When performing temperature detection, the controller 123 only turns on the first switch (for example, one of K1, K2, K3 and K4) and the second switch (for example, one of K5, K6, K7, K8 and K9) in the combination of K1K5, K1K6, K1K7, K1K8, K1K9, K2K5, K2K6, K2K7, K2K8, K2K9, K3K5, K3K6, K3K7, and samples the analog temperature signal detected by the corresponding temperature sensor 113 in the electrode sheet through the ADC sampling unit 122. The controller 123 converts the analog temperature signal collected by the ADC sampling unit 122 into a digital temperature signal, and then transmits the digital temperature signal to the electric field generator 130 through the serial communication unit 124.

[0073] In this embodiment, when performing temperature detection, when the controller 123 controls the first switch K1 and the second switch K5 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first temperature sensor 113 (corresponding to serial number 1) of the first row group; when the controller 123 controls the first switch K1 and the second switch K6 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first to the second temperature sensors 113 (corresponding to serial numbers 1 and 2) of the first row group; when the controller 123 controls the first switch K1 and the second switch K7 to be turned on and the other switches are turned off, the ADC sampling unit 122 samples and obtains the analog temperature signal of the first temperature sensor 113 (corresponding to serial numbers 1 and 2) of the first row group. The analog temperature signals of the first to third temperature sensors 113 (corresponding to numbers 1, 2, and 3) of the first row group are obtained in this way. When the controller 123 controls the first switch K1 and the second switch K8 to be turned on and the other switches to be turned off, the ADC sampling unit 122 samples the analog temperature signals of the first to fourth temperature sensors 113 (corresponding to numbers 1, 2, 3, and 4) of the first row group. When the controller 123 controls the first switch K1 and the second switch K9 to be turned on and the other switches to be turned off, the ADC sampling unit 122 samples the analog temperature signals of the first to fifth temperature sensors 113 (corresponding to numbers 1, 2, 3, 4, and 5) of the first row group. Similarly, the analog temperature signals generated by the temperature sensors 113 of the other row groups can be obtained. The serial communication unit 124 is controlled by the controller 123 , which converts the analog temperature signal collected by the ADC sampling unit 122 into a digital temperature signal. The controller 123 transmits the digital temperature signal of each temperature sensor 113 to the electric field generator 130 in serial via the serial communication unit 124 .

[0074] Preferably, the temperature sensor 113 is a thermistor. Figure 2 As shown, when serial numbers 1-13 are used as temperature measurement point numbers, the resistance value of the thermistor corresponding to each temperature measurement point number can be represented by Rtn. For example, the resistance value of the thermistor corresponding to temperature measurement point number 1 is Rt1, which is specifically the resistance value of the first thermistor in the first row group at the corresponding temperature. The resistance value of the thermistor corresponding to temperature measurement point number 2 is Rt2, which is specifically the resistance value of the second thermistor in the first row group at the corresponding temperature, and so on.

[0075] After the controller 123 obtains the analog temperature signal corresponding to the temperature measurement point number, the analog temperature signal is the resistance value of one or more corresponding combinations of all temperature sensors 113 of the electrode sheet 100, and calculates the actual temperature of the thermistor corresponding to the temperature measurement point number using the following formula (1):

[0076]

[0077] Wherein, Tn is the actual temperature of the thermistor corresponding to the temperature measurement point number n, x is the analog temperature signal corresponding to the temperature measurement point number n obtained by sampling, span is the maximum range of the ADC sampling unit 122. For example, when the ADC sampling unit 122 uses a 16-bit sampling chip, span is 65535. R is the resistance value of the voltage divider resistor, such as the resistance value of the voltage divider resistor R1, R2, R3 or R4.

[0078] The resistance value of the thermistor corresponding to the temperature measurement point number can be calculated using the following formula (2):

[0079]

[0080] It can be understood that by modifying formula (2), when the resistance value of the thermistor corresponding to the temperature measurement point number is obtained, the analog temperature signal of the thermistor corresponding to the temperature measurement point number can be obtained:

[0081]

[0082] Where y is the analog temperature signal of the thermistor corresponding to the temperature measurement point number.

[0083] It should be noted that by selecting voltage divider resistors with appropriate resistance values, such as voltage divider resistors R1, R2, R3 and R4, the current flowing through the thermistor can be limited to prevent excessive current from causing excessive temperature rise of the thermistor, thereby affecting the test accuracy and even causing damage to the thermistor in severe cases.

[0084] Specifically, after pre-determining the switch combination with the analog temperature signal, the controller 123 controls the temperature detection switch unit 121 to turn on the first switch (for example, one of K1, K2, K3 and K4) and the second switch (for example, one of K5, K6, K7, K8 and K9) in the switch combination with the analog temperature signal, so that the analog temperature signal detected by the corresponding thermistor is sampled by the ADC sampling unit 122, and the corresponding temperature is calculated by the above formulas (1)-(3).

[0085] For example, Figure 2 Taking the temperature detection of the first row group as an example, the controller 123 first controls the first switch K1 and the second switch K5 to be turned on, and the other switches to be turned off. At this time, the analog temperature signal of the first thermistor in the first row group is sampled and obtained. The actual temperature T1 of the thermistor can be calculated by the above formula (1), and the resistance Rt1 of the thermistor can be calculated by the above formula (2).

[0086] Next, the first switch K1 and the second switch K6 are controlled to be turned on, and the other switches are turned off. At this time, the analog temperature signal of the first to second thermistors in the first row group is sampled and obtained. The resistance value of the first to second thermistors combined can be calculated by the above formula (2), that is, Rt1+Rt2. Since Rt1 has been obtained, Rt2 can be calculated. Then, the analog temperature signal of the second thermistor can be calculated based on Rt2 and the above formula (3). The analog temperature signal is substituted into the above formula (1) to calculate the actual temperature T2 of the second thermistor.

[0087] Next, the first switch K1 and the second switch K7 are controlled to be turned on, and the other switches are turned off. At this time, the analog temperature signal of the first to third thermistors in the first row group is sampled and obtained. The resistance value of the first to third thermistors combined can be calculated by the above formula (2), that is, Rt1+Rt2+Rt3. Since Rt1 and Rt2 have been obtained, Rt3 can be calculated. Then, the analog temperature signal of the third thermistor can be calculated based on Rt3 and the above formula (3). The analog temperature signal is substituted into the above formula (1) to calculate the actual temperature T3 of the third thermistor.

[0088] Next, the first switch K1 and the second switch K8 are controlled to be turned on, and the other switches are turned off. At this time, the analog temperature signals of the first to fourth thermistors in the first row group are sampled and obtained. The resistance value of the first to fourth thermistors combined can be calculated by the above formula (2), that is, Rt1+Rt2+Rt3+Rt4. Since Rt1, Rt2 and Rt3 have been obtained, Rt4 can be calculated. Then, the analog temperature signal of the fourth thermistor can be calculated based on Rt4 and the above formula (3). The analog temperature signal is substituted into the above formula (1) to calculate the actual temperature T4 of the fourth thermistor.

[0089] Next, the first switch K1 and the second switch K9 are controlled to be turned on, and the other switches are turned off. At this time, the analog temperature signals of the first to fifth thermistors in the first row group are sampled and obtained. The resistance value of the first to fifth thermistors after the combination can be calculated by the above formula (2), that is, Rt1+Rt2+Rt3+Rt4+Rt5. Since Rt1, Rt2, Rt3 and Rt4 have been obtained, Rt5 can be calculated. Then, the analog temperature signal of the fifth thermistor can be calculated based on Rt5 and the above formula (3). The analog temperature signal is substituted into the above formula (1) to calculate the actual temperature T5 of the fifth thermistor.

[0090] for Figure 2The temperature detection process of the second and third row groups is the same as that of the first row group. Please refer to the above for details and will not be repeated here. In this way, the temperature of the thermistor corresponding to each electrode element 112 can be obtained, that is, the temperature at the electrode element 112 can be obtained.

[0091] Therefore, by controlling the combination of the first switch (for example, one of K1, K2, K3 and K4) and the second switch (for example, one of K5, K6, K7, K8 and K9), not only can 100% coverage of the temperature sensor 113 be achieved without increasing the number of cores of the first cable 115, thereby avoiding excessive weight on the electrode sheet 100 and maintaining the application effect of the electrode sheet 100, but also by screening the switch combination of the first switch (for example, one of K1, K2, K3 and K4) and the second switch (for example, one of K5, K6, K7, K8 and K9), and performing temperature detection based on the screened switch combination, the speed of temperature detection can be improved and resource usage can be reduced while ensuring that each temperature sensor 113 is detected.

[0092] The controller 123 can also determine the number of the plurality of electrode elements 112, the number of row groups, and the number of column groups according to the combination of the simulated temperature signals. Figure 2 As shown, under normal conditions of the electrode sheet, among the aforementioned 20 combinations, K1K5, K1K6, K1K7, K1K8, K1K9, K2K5, K2K6, K2K7, K2K8, K2K9, K3K5, K3K6, and K3K7 have analog temperature signals. The combinations with analog temperature signals are exactly the same as the number of electrode elements 112 in the electrode sheet. Therefore, the number of multiple electrode elements 112 in the electrode sheet can be determined based on the combinations with analog temperature signals. In addition, in the combinations with analog temperature signals, the number of row groups is the same as the number of first switches, and the number of column groups is the same as the number of second switches, as shown in FIG. Figure 2 As shown, the plurality of electrode elements 112 are arranged in three rows and five columns. In the combination with the analog temperature signal, the number of first switches present is three (first switches K1, K2, and K3), and the number of second switches present is five (second switches K5, K6, K7, K8, and K9), i.e., the number of row groups is three and the number of column groups is five. Therefore, the number of row groups and column groups of the plurality of electrode elements 112 can be determined based on the combination with the analog temperature signal. In addition, the number of cores of the first cable 115 can be determined based on the number of row groups and column groups of the plurality of electrode elements 112 of the electrode sheet 100. The number of cores of the first cable 115 is the number of row groups plus the number of column groups plus one of the plurality of electrode elements 112 of the electrode sheet 100.

[0093] The controller 123 is also used to determine whether there is an abnormal temperature sensor 113 in the corresponding electrode sheet according to the number of row groups and column groups of the plurality of electrode elements 112 and the analog temperature signal. It is assumed that all temperature sensors 113 and temperature detection circuit connections of the electrode sheet 100 are normal, such as Figure 2 As shown, the electric field generator 130 can be turned off first. At this time, the analog temperature signals generated by each temperature sensor 113 of the electrode sheet are approximately the same, and the corresponding actual temperatures and resistance values are also approximately the same. For example, the resistance values Rt1, Rt2, Rt3, Rt4 and Rt5 of the thermistors corresponding to the temperature measurement points 1, 2, 3, 4 and 5 are approximately the same. The controller 123 controls the first switch K1 and the second switch K9 to be turned on, and the other switches to be turned off, so that the combined resistance value of the five thermistors in the first row group can be Rt. Since Rt= Rt1+Rt2+Rt3+Rt4+Rt5, and Rt1, Rt2, Rt3, Rt4, and Rt5 are approximately the same. Therefore, Rt is approximately equal to five times Rt1. Based on the sampled analog temperature signal, the actual temperature Tz1 corresponding to Rt1 can be calculated using the above formula. Similarly, the actual temperature Tz2 corresponding to the average resistance of the five thermistors in the second row group and the actual temperature Tz3 corresponding to the average resistance of the three thermistors in the third row group can be calculated. Tz1, Tz2, and Tz3 are approximately the same. Therefore, when obtaining Tz1, Tz2, and Tz3, if Tz1, Tz2, and Tz3 are approximately the same, then there are no abnormal thermistors or abnormal circuit connections in the electrode sheet 100. If there are large differences between Tz1, Tz2, and Tz3, then there are abnormal thermistors or abnormal circuit connections in the electrode sheet 100. Therefore, whether or not there is an abnormal temperature sensor 113 in the electrode sheet 100 can be determined based on the number of row groups and column groups of the plurality of electrode elements 112 and the analog temperature signal.

[0094] refer to Figure 1 As shown, a second connector 150 is provided between the adapter 120 and the electric field generator 130. The second connector 150 is suitable for connecting the electric field generator 130 to the adapter 120. The adapter 120 also has a second cable 125. The second connector 150 includes a second plug 151 provided at the end of the second cable 125 away from the adapter 120, and a second socket 152 provided on the electric field generator 130. The second plug 151 and the second socket 152 are press-type spring connectors, that is, the second connector 150 uses a connector method to connect the adapter 120 and the electric field generator 130.

[0095] refer to Figure 3As shown, when there are four electrode sheets, the second cable is an 8-core cable, of which four cores are alternating power lines (a1, a2, a3, and a4) respectively connected to the four first connectors 40, used to provide alternating electrical signals of corresponding directions and polarities, two cores are receive data line RX and transmit data line TX electrically connected to the serial communication unit 124 in the adapter 120, and the remaining two cores are power lines and ground lines that provide DC power VCC to at least one temperature sensor 113 of each electrode sheet 100. The controller 123 converts the analog temperature signal sampled by the ADC sampling unit 122 of the corresponding temperature sensor 113 into a digital temperature signal through calculation, and the controller 123 controls the serial communication unit 124 to transmit the digital temperature signal to the electric field generator 130 via the second connector 150. That is, the analog temperature signal collected by the ADC sampling unit 122 of the adapter 120 is converted into a digital temperature signal by the controller 123, and then transmitted to the electric field generator 130 via the serial communication unit 124, the transmit data line TX connected to the serial communication unit 124, and the second connector 150. It should be noted that the controller 123 can also transmit other information such as the number of the plurality of electrode elements 112 in the electrode sheet, the number of row groups, the number of column groups, and the presence or absence of abnormal temperature sensors 113 through the serial communication unit 124, which is not limited here.

[0096] In the above embodiment, the plurality of electrode elements 112 on the electrode sheet 100 are connected in groups, the temperature sensors 113 in the same row group are connected in series, and then connected to the DC power supply VCC through the first switch (one of K1, K2, K3 and K4) and the voltage divider resistor (one of R1, R2, R3 and R4) connected in series, and the ground terminals 113B of the temperature sensors 113 in the same column group are connected together, and then connected to the ground pin GND through the second switch (one of K5, K6, K7, K8 and K9), and the first switch (one of K1, K2, K3 and K4) and the second switch (one of K5, K6, K7, K8 and K9) in the combination with the analog temperature signal are controlled so that the analog temperature signal detected by each temperature sensor 113 is sampled separately, thereby achieving 100% temperature sensor coverage without increasing the number of cable cores of the first cable 115, thereby avoiding excessive weight on the electrode sheet 100 and maintaining the application effect of the electrode sheet 100. For example, when Figure 2When the coverage rate of the temperature sensors 113 on the electrode sheet 100 reaches 100%, the first cable 115 in the related art requires 15 cores to achieve this, resulting in the first cable 115 being very thick, having poor flexibility, and having a poor application effect. In this embodiment, the coverage rate of the temperature sensors 113 can be guaranteed to reach 100% without increasing the number of cores of the first cable 115, thereby achieving comprehensive temperature monitoring of each electrode element 112 in the electrode sheet 100. At the same time, before performing temperature detection, by screening the switch combination of the first switch (one of K1, K2, K3 and K4) and the second switch (one of K5, K6, K7, K8 and K9), and performing temperature detection based on the screened switch combination, the temperature detection speed can be improved while ensuring that each temperature sensor 113 is detected, and resource usage can be reduced.

The electrode sheet 100' of this embodiment has a different number of row groups and column groups from the electrode sheet 100 of the first embodiment. The electrode sheet 100' has four row groups and four column groups. Since the electrode elements 112, temperature sensors 113 and diodes 114 are the same as those of the first embodiment, the numbers of the first embodiment are used. The number of electrode elements 112 and temperature sensors 113 in the first three rows of the electrode sheet 100' of this embodiment is 4 each, the number of electrode elements 112 and temperature sensors 113 in the last row is 1 each, the number of electrode elements 112 and temperature sensors 113 in the first column is 4 each, and the number of electrode elements 112 and temperature sensors 113 in the last three column is 3 each. The number of wire cores in the first cable 115' of the electrode sheet 100' is 9.

The number of electrode elements 112 and temperature sensors 113 in each group and column group is different. Since the electrode elements 112, temperature sensors 113 and diodes 114 are the same as those in the first and second embodiments, the numbers of the first embodiment are used. In the electrode sheet 100" of this embodiment, the number of electrode elements 112 and temperature sensors 113 in the first row group are all 4, the number of electrode elements 112 and temperature sensors 113 in the last three rows groups are all 3, the number of electrode elements 112 and temperature sensors 113 in the first three columns groups are all 4, and the number of electrode elements 112 and temperature sensors 113 in the last column group are all 1. The number of wire cores of the first cable 115" of the electrode sheet 100" is 9. The four first switches (one of K1, K2, K3 and K4) of the adapter 120" are respectively connected to a signal terminal 113A at the end of a corresponding row group, and the four second switches (one of K5, K6, K7 and K8) of the adapter 120" are respectively connected to the ground terminal 113B of all temperature sensors 113 of a corresponding column group, and the remaining second switch (K9) is not connected to any temperature sensor 113.

[0099] In other embodiments, Figure 6 As shown, Figure 6 for Figure 1The structural diagram of an electrode sheet 100' and an adapter 120' in the fourth embodiment is different from the electrode sheets 100, 100', and 100' of the aforementioned three embodiments in that the electrode sheet 100' of this embodiment has a different number of electrode elements 112 from the electrode sheets 100, 100', and 100' of the aforementioned three embodiments. The number of electrode elements 112 and temperature sensors 113 in the electrode sheet 100'' of this embodiment is 9, and they are arranged in three rows and four columns. Since the electrode elements 112, temperature sensors 113 and diodes 114 are the same as those in the first and second embodiments, the reference numerals of the first embodiment are used. The number of electrode elements 112 and temperature sensors 113 in the first two rows of the electrode sheet 100'' of this embodiment is 4, the number of electrode units 112 and temperature sensors 113 in the last row is 1, the number of electrode elements 112 and temperature sensors 113 in the first column is 3, and the number of electrode units 112 and temperature sensors 113 in the last three columns is 2.

The remaining one first switch (K4) and one second switch (K9) are not connected to any temperature sensor 113.

[0100] from Figure 2 、 Figure 4-Figure 6 It can be seen that when the plurality of electrode elements 112 are configured into at least three row groups and at least three column groups, the number of electrode elements 112 in each row group is not exactly the same, and the number of electrode elements 112 in each column group is not exactly the same. Therefore, before performing temperature detection, all combinations of the first switch and the second switch must be screened to select combinations that can detect analog temperature signals, and then temperature detection is performed based on the combinations that can detect analog temperature signals. When performing temperature detection, the combinations with analog temperature signals are not exactly the same, but the process of screening the combinations with analog temperature signals, performing temperature detection based on the screened combinations with analog temperature signals, determining the number of electrode elements 112, the number of row groups, and the number of column groups, and determining whether there is an abnormal temperature sensor 113 in the electrode sheet is the same, as described above.

[0101] from Figure 2 、 Figure 4-Figure 6It can be seen that the number of first switches is greater than or equal to the number of row groups, and the number of second switches is greater than or equal to the number of column groups. For example, when there are 4 first switches and 5 second switches, they are K1, K2, K3 and K4 and K5, K6, K7, K8 and K9 respectively. However, Figure 2 In the example shown, the first switch K4 is in an open state, that is, it is not connected to any temperature sensor 113 .

The weight is too large, and the application effect of the electrode sheets 100, 100', 100", 100"', 100", 100""', 100""", 100"""' is maintained. In addition, by screening the switch combination of the first switch (K1, K2, K3 and K4) and the second switch (K5, K6, K7, K8 and K9), and performing temperature detection based on the screened switch combination, the speed of temperature detection can be improved and resource usage can be reduced on the basis of ensuring the detection of each temperature sensor 113.
