[0002] With the development of science and technology, in order to better control the operation of various scientific and technological products, various switch devices are often applied in scientific and technological products to achieve the switching between the working state and the suspended working state of various products or cooperating products.

[0003] However, for the switch used to achieve the switching between the working state and the suspended working state of various products or cooperating products, usually at the same moment, only one control signal line of the same switch can be powered on. This means that if multiple signal lines of the switch are powered on simultaneously, it is very likely to cause damage to the switch. And when the number of mechanical switches is large, it means that there are more states of the power-on states of the current channel signal lines of each switch to be managed, and the complexity of control is greatly increased.

[0029] To illustrate the technical solutions described in this application, the following will be described through specific embodiments.

[0030] This application provides a switching channel switching method, which can reduce the control difficulty and debugging difficulty of the overall device and improve the stability of the system.

[0031] Please refer to Figure 1 , Figure 1 which is a flowchart of the implementation of a switching channel switching method provided by an embodiment of this application, including the following steps: This application provides a switching channel switching method, where the control output port of the control board is connected to the control input port of the function board, and the output interface of the function board is connected to the control pins of the RF switch group, including: S11: Receive channel switching control information through the control board.

[0032] S12: Process the channel switching control information through the control board to obtain a control signal, and after performing preset processing on the control signal through the function board, transmit it to the RF switch group.

[0033] S13: Complete the switching of the switching channels through the RF switch group according to the control signal that has been preset-processed through the function board.

[0034] In this embodiment, each hardware is modularized, avoiding system coupling, and the hardware connections of each part of the switch matrix system are ingeniously made, and through the corresponding software control method, the control of this multi-input and multi-output non-full-switching non-holding RF switch matrix is realized.

[0035] The control board is used to receive and process specific RF channel switching instructions and generate a serial control signal for the serial-to-parallel function board.

[0036] The function board receives the serial control signal sent by the control board and converts it into the parallel control signal of the RF switch. The converted parallel control signal will also go through voltage step-up conversion, such as converting the voltage from 1V to 12V, for input to the final RF switch.

[0037] The RF switch group is a combination of mechanical non-latching RF switches adopted by this switch matrix, used to receive the control signal after conversion by the function board and execute the switching of specific RF switches.

[0038] In the embodiment, in order to manage the operating states of multiple switches, make the control more precise, reduce the design and R & D costs of the product, reduce the control difficulty and debugging difficulty of the overall device, improve the stability of the system, and be able to better adapt to the switch expansion requirements, first, the control output port of the control board is connected to the control input port of the function board, and the output interface of the function board is connected to the control pins of the RF switch group. After the control board receives the channel switching control information sent by the host computer, then the control board processes the channel switching control information to obtain a control signal, and after the control signal is preprocessed by the function board, the control signal can be split into multiple signals and transmitted to the RF switch group, so that after the RF switch group recognizes the control signal, it can execute control operations on multiple switches included in the RF switch group to complete the switching of the switch channels, effectively reducing the device control difficulty and improving the control stability.

[0039] As for when to receive the channel switching control information through the control board, it includes but is not limited to the following scenarios: Scenario 1: When the host computer is turned on and the startup fluctuation voltage signal of the host computer is detected, the channel switching control information is received through the control board.

[0040] Scenario 2: When the control board starts and is in the running state, the channel switching control information is received.

[0041] Scenario 3: When it is determined that the work task executed by the target device ends, obtain the user portrait of the user operator of the target device, and according to the user portrait, instruct the host computer to generate the channel switching control information and send the channel switching control information to the control board.

[0042] The user portrait describes the user's habits of executing work tasks based on the target device and the time points of executing each work task. Based on the user's habits and the time points of executing work tasks, the timing of executing the next work task can be determined.

[0043] Therefore, the host computer can be instructed to generate the channel switching control information according to the user portrait and send the channel switching control information to the control board.

[0044] In an example, such as Figure 7, there are x control output ports such as IO1, IO2, IO3...IOx on the control board. These control ports utilize the limited control pins of the control board (MCU) to expand as many serial control signal ports as possible. Each independent IOx can generate an independent serial control signal.

[0045] Now, the IO1 of the control board can be connected to the control input Control interface of a function board. At this time, the serial signal output by the control board's IO1 will pass through the function board to perform the serial-to-parallel operation of the control signal. In this way, a small number of pins of the IO1 interface can control 32 parallel radio frequency switches.

[0046] The control pins of these 32 effective radio frequency switches are respectively distributed in the SW1, SW2, and SW3 output interfaces of the function board. The number of pins of these 3 interfaces, SW1, SW2, and SW3, is 15 each, totaling 45 pins. The specific distribution method of the interface pins is that the 1st to 11th pins of the SW1 interface, the 1st to 11th pins of the SW2 interface, and the 1st to 10th pins of the SW3 interface, a total of 32 pins, are used as the control pins of the radio frequency switches. The remaining pins of SW1, SW2, and SW3, that is, the 12th to 15th pins of SW1, the 12th to 15th pins of SW2, and the 11th to 15th pins of SW3, are all used as the GND of the control lines of the radio frequency switches.

[0047] For example, in the 3x12SF type of switch matrix, the non-holding mechanical radio frequency switch group can select 3 1-to-4 switches SP4T to form Figure 7 the radio frequency switch group in. The control ports of this radio frequency switch group need to be connected to 12 control signal lines led out from SW1, SW2, and SW3.

[0048] Among them, 12 of the 32 effective control pins of the radio frequency switches of the SW1, SW2, and SW3 interfaces on the function board are taken as the control pins of this radio frequency switch group, and the interface pins of the function board SW1, SW2, and SW3 are connected to the corresponding control pins of the switch group. From Figure 10 , the specific wiring method can be seen: SW1_1, SW1_2, SW1_3, and SW1_4 of the function board are respectively connected to 1#1, 1#2, 1#3, and 1#4 of the radio frequency 1 switch in sequence (1#1, 1#2, 1#3, and 1#4 respectively represent the control lines of the 1st, 2nd, 3rd, and 4th channels of the 1st radio frequency switch).

[0049] SW2_1, SW2_2, SW2_3, and SW2_4 of the function board are respectively connected to 2#1, 2#2, 2#3, and 2#4 of the radio frequency 2 switch in sequence (2#1, 2#2, 2#3, and 2#4 respectively represent the control lines of the 1st, 2nd, 3rd, and 4th channels of the 2nd radio frequency switch).

[0050] SW3_1, SW3_2, SW3_3, and SW3_4 of the function board are respectively connected to 3#1, 3#2, 3#3, and 3#4 of the RF switch No. 3 in sequence (3#1, 3#2, 3#3, and 3#4 respectively represent the control lines of channels 1, 2, 3, and 4 of the RF switch No. 3).

[0051] Combined with Figure 2 , in some embodiments, the processing of the channel switching control information by the control board to obtain a control signal includes: S21: Parsing and processing the channel switching control information by the control board to obtain the status word parameters of the global switches of the switch matrix.

[0052] S22: Generating the control word parameters according to the status word parameters, and the control word parameters serve as the control signal.

[0053] In this embodiment, in order to better and more accurately control the switch and thus control the control device, the control board parses and processes the channel switching control information to obtain the status word parameters of the global switches of the switch matrix, so as to record the status of each switch in the switch matrix through the status word parameters of the global switches of the switch matrix. Then, according to the status word parameters, the control word parameters are generated, and the control word parameters serve as the control signal, so as to record the switch information to be operated through the control word parameters, and finally complete the switching of the switch channels.

[0054] In some embodiments, if the number of RF switch groups is greater than or equal to 2, the control word parameters corresponding to each RF switch group are different.

[0055] In this embodiment, in order to meet the control requirements of more switches and make the control more accurate and stable, if the number of RF switch groups is greater than or equal to 2, the control word parameters corresponding to each RF switch group are different.

[0056] Combined with Figure 3 , in some embodiments, the parsing and processing of the channel switching control information by the control board to obtain the status word parameters of the global switches of the switch matrix includes: S31: Parsing and processing the channel switching control information by the control board to obtain the switch number to be switched by the RF switch group and the internal channel number corresponding to the switch number.

[0057] S32: If it is determined that the switch number and the internal channel number corresponding to the switch number are the target switch number and the target internal channel number, then update the historical status word parameters according to the target switch number and the target internal channel number to obtain the status word parameters of the global switches of the switch matrix.

[0058] In this embodiment, in order to more precisely control the opening or closing of the switch, the control board analyzes and processes the channel switching control information to obtain the switch number that the RF switch group needs to switch and the internal channel number corresponding to the switch number, so as to know the switch number that needs to be controlled for switching and the internal channel number corresponding to the switch number. If it is determined that the switch number and the internal channel number corresponding to the switch number are the target switch number and the target internal channel number, the historical status word parameter is updated according to the target switch number and the target internal channel number to obtain the status word parameter of the global switch of the switch matrix.

[0059] Exemplarily, combined with Figure 8 , the control board analyzes the channel switching instruction in the receive buffer to obtain the switch number Switch_Num that the RF switch matrix currently needs to switch and the channel number Switch_Port_Num inside the switch. For example, Figure 7 in the RF switch matrix, the switch numbers of the switches in RF switch group 1 include 1, 2, and 3, and the channel numbers inside each corresponding switch include 1, 2, 3, and 4. To ensure the correctness of the switch number and the channel number and prevent the generation of incorrect status words, it is necessary to judge the values of the switch number and the channel number. In the 3x12SF switch matrix system, there are a total of 3 1-to-4 switches. Then the switch number Switch_Num can take values from 1 to 3. Also, since each switch is 1-to-4, the internal channel number Switch_Port_Num can take values from 1 to 4.

[0060] If the switch number and the channel number in the instruction are correct, the global array SW_STA is used to store the status of the switch to be switched in the system, that is, SW_STA[Switch_Num] = Switch_Port_Num; for example, Switch_Num = 1, Switch_Port_Num = 4, then correspondingly SW_STA[1] = 4, which means that the switch matrix will switch to channel 4 of switch 1.

[0061] In the 3x12SF switch matrix system, there are a total of 3 1-to-4 switches. Among them, the initial state of the switch status control word SW_STA is: SW_STA[1] = 0, SW_STA[2] = 0, SW_STA[3] = 0; that is, it represents that switches 1, 2, and 3 are all in the channel closed state in sequence. If the switch matrix is to switch to channel 4 of switch 1, then the corresponding value of the global status control word SW_STA at this time is: SW_STA[1] = 4, SW_STA[2] = 0, SW_STA[3] = 0.

[0062] In the process of generating the status word parameters of the global switches of the entire switch matrix, the status of the switches to be switched currently is stored in the system using the array SW_STA. Each group element of the array SW_STA stores the status of the corresponding switch independently. The change in the status of any one switch will not cause the status of other switches to change. And the array SW_STA is a global variable. During the operation of the entire switch matrix, it will not be reset and will always correctly record the status of each switch.

[0063] It can be seen that the method for managing the channel switching status of the switch matrix proposed in this application is very stable and efficient. The status of each switch is stored independently. After each switch switching instruction is received, the corresponding element of the array SW_STA will be updated synchronously to store the status of the corresponding switch, while the status of other switches remains stored without being lost.

[0064] In this way, on the one hand, it ensures the storage of the status of non-hold RF switches. Even if the number of switches is large, they can be stored independently. On the other hand, there is no need to design a separate and complex hardware device to manage the channel status of these switches, reducing the R & D and production costs of the product.

[0065] Combined with Figure 4 , in some embodiments, generating the control word parameter according to the status word parameter, and using the control word parameter as the control signal includes: S41: Determine the starting position status information of the target switch to be switched in the RF switch group according to the status word parameter.

[0066] S42: Determine the target offset of the target switch to be switched in the RF switch group according to the switch number of the target switch to be switched in the RF switch group and the preset control line offset information corresponding to the target switch to be switched.

[0067] S43: Determine the control word parameter according to the target offset and the starting position status information of the target switch to be switched in the RF switch group.

[0068] In this embodiment, in order to be able to switch the switch channels more accurately, first determine the starting position status information of the target switch to be switched in the RF switch group according to the status parameter, so as to determine the target offset of the target switch to be switched in the RF switch group according to the switch number of the target switch to be switched in the RF switch group and the preset control line offset information corresponding to the target switch to be switched, and then determine the control word parameter according to the target offset and the starting position status information of the target switch to be switched in the RF switch group.

[0069] In one embodiment, combined with Figure 9, it is necessary to generate a 32-bit control word parameter LocalVal according to the status word parameter SW_STA[Switch_Num] of the global switch of the switch matrix. First, define a 32-bit control word parameter LocalVal variable. Each bit in the 32 bits of the localVal variable value exactly corresponds to the 32-bit parallel control signal output by the function board. Each time the process of generating the control word parameter is entered, each bit of localVal is initialized to 0, that is, localVal = 0x00000000; The purpose of initializing the localVal variable in this way is to ensure that it will be automatically cleared before each loop entry, avoiding incorrect status values of localVal.

[0070] Next, according to the status word parameter SW_STA[Switch_Num] of the global switch of the switch matrix, calculate the starting position status Start_Index of each switch control line in the 32-bit control word LocalVal, that is, confirm the starting point of each switch. The starting position statuses of RF switch 1, switch 2, and switch 3 are regarded as the value statuses of bit0, bit1, and bit2, bit3 of the control word LocalVal respectively.

[0071] The operation implemented by the SET_PORT_VAL(SW_STA[Switch_Num]) expression in SET_PORT_VAL(SW_STA[Switch_Num]) is: shift the value 0x00000001 to the left by a specific number of bits, and the specific number of bits is obtained by subtracting 1 from the value of the parameter SW_STA[Switch_Num] inside the expression parentheses. For SW_STA[Switch_Num], when the switch number Switch_Num = 1, that is, SW_STA[1] = 4. So the expression SET_PORT_VAL(SW_STA[Switch_Num]) is simplified to SET_PORT_VAL(4), and further obtained that 0x00000001 is shifted left by (4 - 1) bits, that is, 0x00000001 << 3.

[0072] In short, the value of the SET_PORT_VAL(SW_STA[Switch_Num]) expression confirms the starting position status Start_Index of the signal line of the switch with the switch number Switch_Num to be switched in the 32-bit control word LocalVal. Calculate the offset Offset = (Switch_Num - 1) * delta. Here, the meaning of the offset Offset is the index difference of the 1st control line of each switch relative to SW1_1 (that is, bit0).

[0073] Each switch's control signal line has an index difference relative to SW1_1 of the function board.

[0074] The offset of the control line of Switch No. 1, Offset, is 0 because the first control pin of Switch No. 1 is exactly connected to SW1_1.

[0075] The offset of Switch No. 2, Offset, is 11 because the first control pin of Switch No. 2 is connected to SW2_1 and the index difference is 11.

[0076] The offset of Switch No. 3, Offset, is 22 because the first control pin of Switch No. 3 is connected to SW3_1 and the index difference is 22.

[0077] Note: In Offset = (Switch_Num - 1) * delta, Switch_Num is the switch number and delta is the coefficient for corresponding calculations. For example, the coefficient for calculating the control line offset of Switch No. 1, Offset, is 0; the coefficient for calculating the control line offset of Switch No. 2, Offset, is 11; and the coefficient for calculating the control line offset of Switch No. 3, Offset, is 22.

[0078] According to the calculated starting position state Start_Index and the calculated offset Offset, a temporary value of the control word LocalVal specific to each switch is obtained, that is, Start_Index << Offset.

[0079] Then, the temporary control words of each switch are combined into the final control word LocalVal through an operation such as LocalVal |=, that is, LocalVal |= Start_Index << Offset.

[0080] For the obtained final 32-bit control word LocalVal, only one bit of the control line of the corresponding switch is 1 and the rest are 0 at the same moment. For example, for Switch No. 1, 1#1, 1#2, 1#3, and 1#4 respectively represent the control lines of channels 1, 2, 3, and 4 of the first RF switch, and also correspond to bit0, bit1, bit2, and bit3 of the control word respectively. At the same moment, only one of bit0, bit1, bit2, and bit3 is 1 and the rest of the bits are 0. This ensures that only one signal line of the same switch is powered on at a specific moment, and it is impossible for multiple signal lines of the same switch to be powered on simultaneously, which may cause damage to potential non-hold-type RF switches.

[0081] In some embodiments, the control board has at least two control output ports, each of the control output ports is respectively connected to a control input port of a function board, and the output interface of each function board is connected to a control pin of a RF switch group.

[0082] In this embodiment, in order to better control the switch and reduce the cost of switch control, the control board has at least two control output ports. Each of the control output ports is respectively connected to the control input port of a function board, and the output interface of each function board is connected to the control pin of a radio frequency switch group. The control board, combined with the corresponding number of function boards, can easily and conveniently expand more switch matrices for radio frequency input and output, greatly reducing the complexity of hardware connection and software control. The entire device has a delicate structure, and the corresponding switch matrix can greatly reduce the hardware volume. At the same time, since each radio frequency switch group corresponds to a unique 32-bit switch control word LocalVal, for example, radio frequency switch group 1 corresponds to LocalVal1, radio frequency switch group 2 corresponds to LocalVal2... radio frequency switch group X corresponds to LocalValX. In this way, each switch group will be independently controlled by the corresponding status word LocalValX, and there will be no interference phenomenon in the control signals of different switch groups.

[0083] For example, the IO1 interface of the control board is connected to function board 1, and function board 1 is connected to radio frequency switch group 1, thus forming a 3x12SF switch matrix. If it is necessary to add a 6x24SF switch matrix at this time, then on the basis of the 3x12SF switch matrix formed by IO1, IO2 can be used to connect to function board 2, and function board 2 is then connected to radio frequency switch group 2 to form a 6x24SF switch matrix. If 6x24SF still does not meet the requirements, this expansion idea can be continued until the IOX of the control board is connected to function board X, and function board X is then connected to radio frequency switch group X. It should be noted that for the newly expanded additional switch group, the number of switches corresponding to the switch group is not limited to 3 switches.

[0084] In some embodiments, the signal type of the control signal is a serial signal.
