The resistor group 43 is 5 high-precision voltage dividing resistors, and is respectively connected in series to the dc power supply VCC and 5 signal lines (No. 6, no. 7, no. 8, no. 9, and No. 10) of the second connector 31 that transmit analog temperature signals (voltage values of the temperature detection units) detected by the corresponding temperature detection units, that is, each temperature sampling point is connected to the dc power supply VCC through the corresponding voltage dividing resistor. The 5 voltage dividing resistors are respectively connected in series with the corresponding temperature detection units for voltage division, so that the voltage value of the temperature detection units can be calculated, and the voltage value can be converted into a digital temperature signal through the ADC sampling unit 46 to obtain an AD sampling value, wherein the AD sampling value corresponds to the digital temperature. Therefore, the AD sample values may be partitioned by temperature ranges so as to identify the types of the corresponding electrode pads 50 and determine whether temperature abnormality occurs in the corresponding electrode pads 50. If the AD sampling value is significantly deviated from the detected temperature range, for example, lower than 0 ℃ or higher than 50 ℃, it is determined that the temperature detection unit and the electrode plate unit 51 are not provided at the sampling point corresponding to the AD sampling value, so as to determine the number of the electrode plate units 51 to identify the type of the electrode plate 50.

Alternatively, the filter uses a first order RC low pass filter with a cut-off frequency of the alternating electrical signal AC frequency of less than 1/10. Optionally, a voltage follower may be added to the filtering unit 47 to optimize the sampling of the ADC sampling unit 46.

The ADC sampling unit 46 has 5 acquisition channels 1, 2, 3, 4, 5. The 5 acquisition channels of the ADC sampling unit 46 are electrically connected to a corresponding set of filters of the filtering unit 47. Specifically, 5 acquisition channels of the ADC sampling unit 46 are respectively connected to the ports 6, 7, 8, 9, and 10 of the filtering unit 47 in a one-to-one correspondence manner to be electrically connected to a corresponding set of filters. The ADC sampling unit 46 may convert the plurality of analog temperature signals filtered by the filtering unit 47 into a plurality of digital temperature signals to obtain a plurality of AD sampling values. The plurality of AD samples converted by the ADC sampling unit 46 are controlled by the first controller 45 to be serially transmitted to the first adaptor 60 by the first communication unit 42.

The second communication unit 61 is connected between the four first connectors 25 and the second controller 62. The second controller 62 performs data interaction with the first communication units 42 of the 4 second adapters 40 through the second communication unit 61. Alternatively, the second communication unit 61 uses a UART unit. The first controller 45 may send the feedback signal of the corresponding handshake chip 54 to the second controller 62, so that the second controller 62 determines whether the corresponding first controller 45 and the handshake chip 54 complete handshake communication according to the feedback signal of the handshake chip 54. The first controller 45 may further send the plurality of AD samples to the second controller 62, so that the second controller 62 identifies the type of the corresponding electrode sheet 50 according to the plurality of AD samples when the electrode sheet 50 is qualified, and/or determines whether the temperature of the corresponding electrode sheet 50 is abnormal according to the plurality of AD samples in the process that the electric field generator 10 transmits the alternating electric signal to the corresponding electrode sheet 50.

The second controller 62 is connected substantially between the second communication unit 61 and the third communication unit 63. The third communication unit 63 is electrically connected to the electric field generator 10 substantially through the third connector 22. The second controller 62 performs data interaction with the electric field generator 10 through the third communication unit 63.

As can be seen from the foregoing description, the determination of the handshake communication, the identification of the type of the electrode pads, and the identification of whether the electrode pads have a temperature abnormality may be implemented by the first controller 45 in the second adaptor 40, the second controller 62 in the first adaptor 60, or the electric field generator 10, which is not limited herein. It should be noted that the number of the electrode pads 50, the number of the electrode pad units 51 per electrode pad 50, the number of the temperature detection units, and the like are exemplary illustrations and are not intended to limit the present application.

In the above embodiment, the plurality of electrode sheet units 51 are configured into at least three row groups and at least three column groups, and the signal terminals of the corresponding temperature detection units in each column group are connected together as temperature sampling points, the ground terminals of the corresponding temperature detection units in each row group are connected to the ground pin GND through the switch unit, and the handshake chip 54 performs handshake communication with the electric field generator 10 to determine the connection state of the electrode sheet 50, wherein after the handshake communication between the handshake chip 54 and the electric field generator 10 is completed, the switch state of the switch unit 44 is configured to make the analog temperature signals detected by the corresponding temperature detection units in each row group be sampled at the same time by the corresponding temperature sampling points, so that the coverage rate of the temperature sensor can be effectively increased under the condition of controlling the number of cable cores, the load of the electrode sheet 50 is prevented from being too large, and the application effect of the electrode sheet 50 is maintained; meanwhile, based on the AD sampling value obtained by the sampling analog-to-digital conversion, the type identification of the electrode sheet 50 and the identification of whether the temperature abnormality occurs in the electrode sheet 50 can be realized.

The invention also provides a temperature detection method of the tumor electric field treatment system 1000, which is shown in fig. 4 and comprises the following steps:

in step S1, handshake communication is performed with the handshake chip 54 through the adaptor unit to determine the connection state of the corresponding electrode pad 50.

In step S2, when each electrode pad 50 is successfully connected to the adapter unit, the switching state of the switching unit 44 is configured by the adapter unit, so that the temperature signals detected by the corresponding temperature detection units in each row group are simultaneously sampled by the corresponding temperature sampling points.

Optionally, the method further comprises: and identifying the type of the corresponding electrode plate 50 according to the sampled temperature signal detected by each temperature detection unit. For example, according to the sampled analog temperature signal detected by each temperature detection unit, a plurality of AD sampling values are obtained through analog-to-digital conversion; and determining the number of 50 electrode sheet units 51 of the corresponding electrode sheet according to the AD sampling values, and determining the type of the corresponding electrode sheet 50 according to the number of the electrode sheet units 51.

Optionally, in the process of transmitting the alternating electrical signal to the corresponding electrode sheet 50 by the electric field generator 10, the method further includes: and adjusting the parameters of the alternating electric signal according to the AD sampling values.

For example, the flow 100 of handshaking, temperature detection, and electric field control of the tumor electric field treatment system 1000 is as shown in fig. 5. The process 100 can be applied to the electric field tumor therapy system 1000 shown in fig. 1 for electric field tumor therapy. The process 100 is not limited to be applied to the example shown in fig. 1, and the process 100 is also applied to the examples shown in fig. 7 and 8. The following steps are presented for the example shown in fig. 1.

In step 101, the tumor electric field treatment system 1000 is connected. Specifically, 4C-shaped electrode plates 50 are connected to a corresponding one of the second adapters 40, 4 second adapters 40 are connected to one of the first adapters 60, the first adapters 60 are connected to the electric field generator 10, and the electric field generator 10 is connected to the adapted power supply.

In step 102, it is detected whether a user issues a command to turn on the electric field. If the command for turning on the electric field is not detected, repeating step 102; if the electric field opening command is detected, step 103 is entered.

In step 103, after the electric field generator 10 of the tumor electric field treatment system 1000 sends a handshake signal to the X1 port (the first connector 25-X1, the second connector 40) through the first adapter 60, the first controller 45 of the second adapter 40 connected to the first connector 25-X1 receives data transmitted by the No. 5 wire on the corresponding second connector 31 to determine whether the handshake has passed, and if not, the process goes to step 105; if so, go to step 106. This decision step may occur in the second adaptor 40, in the first adaptor 60 or in the electric field generator 10. In an embodiment the determining step occurs in the second adaptor 40. Specifically, when the electrode plate 50X1 is connected normally, the handshake chip 54 can receive a handshake request signal of the electric field generator 10 and feed back a handshake state to the first controller 45 of the second adapter 40, and the first controller 45 of the second adapter 40 determines that the handshake is successful. On the contrary, when the electrode plate 50X1 is abnormally connected, the first controller 45 of the second adaptor 40 cannot obtain the feedback signal of the handshake chip 54, and the first controller 45 of the second adaptor 40 determines that the handshake fails.

In step 105, the tumor e-field therapy system 1000 issues an alarm due to a handshake failure, and then proceeds to step 102.

In step 106, after the electric field generator 10 of the electric field tumor therapy system 1000 sends a handshake signal to the X2 port (the first connector 25-X2, the second connector 40) through the first adapter 60, the first controller 45 of the second adapter 40 connected to the first connector 25-X2 receives data transmitted by the No. 5 wire on the corresponding second connector 31 to determine whether the handshake signal passes, and if the handshake signal does not pass, the process goes to step 102; if so, step 107 is entered. This decision step may occur in the second adaptor 40, in the first adaptor 60 or in the electric field generator 10. The decision step in the embodiment takes place in the second adapter 40. Specifically, when the electrode plate 50X2 is connected normally, the handshake chip 54 can receive a handshake request signal of the electric field generator 10 and feed back a handshake state to the first controller 45 of the second adapter 40, and the first controller 45 of the second adapter 40 determines that the handshake is successful. On the contrary, when the electrode plate 50X2 is abnormally connected, the first controller 45 of the second adaptor 40 cannot obtain the feedback signal of the handshake chip 54, and the first controller 45 of the second adaptor 40 determines that the handshake fails.

In step 107, after the electric field generator 10 of the electric field tumor therapy system 1000 sends a handshake signal to the Y1 port (the first connector 25-Y1 and the second connector 40) through the first adapter 60, the first controller 45 of the second adapter 40 connected to the first connector 25-Y1 receives data transmitted by the No. 5 wire on the corresponding second connector 31 to determine whether the handshake has passed, and if not, the process goes to step 102; if so, go to step 108. This decision step may occur in the second adaptor 40, in the first adaptor 60 or in the electric field generator 10. In an embodiment the determining step occurs in the second adaptor 40. Specifically, when the electrode plate 50Y1 is connected normally, the handshake chip 54 can receive a handshake request signal of the electric field generator 10 and feed back a handshake state to the first controller 45 of the second adapter 40, and the first controller 45 of the second adapter 40 determines that the handshake is successful. On the contrary, when the electrode plate 50Y1 is abnormally connected, the first controller 45 of the second adaptor 40 cannot obtain the feedback signal of the handshake chip 54, and the first controller 45 of the second adaptor 40 determines that the handshake fails.

In step 108, after the electric field generator 10 of the electric field tumor therapy system 1000 sends a handshake signal to the Y2 port (the first connector 25-Y2, the second connector 40) through the first adapter 60, the first controller 45 of the second adapter 40 connected to the first connector 25-Y2 receives data transmitted by the No. 5 wire on the corresponding second connector 31 to determine whether the handshake signal passes, and if the handshake signal does not pass, the process goes to step 102; if so, go to step 109. This decision step may occur in the second adaptor 40, in the first adaptor 60 or in the electric field generator 10. In an embodiment the determining step occurs in the second adaptor 40. Specifically, when the electrode plate 50Y2 is connected normally, the handshake chip 54 can receive a handshake request signal of the electric field generator 10 and feed back a handshake state to the first controller 45 of the second adapter 40, and the first controller 45 of the second adapter 40 determines that the handshake is successful. On the contrary, when the electrode plate 50Y2 is abnormally connected, the first controller 45 of the second adaptor 40 cannot obtain the feedback signal of the handshake chip 54, and the first controller 45 of the second adaptor 40 determines that the handshake fails.

After receiving the handshake signals of the tumor electric field therapy system 1000 in steps 103, 106, 107, and 108, the second adaptor 40 needs to control the switch module 44 through the first controller 45, so that the No. 4 wire of the second connector 31 is electrically connected to the ground pin GND, so that the handshake chip 54 can work normally. If the connections between the electric field generator 10 and the first adapter 60, between the first adapter 60 and the second adapter 40, and between the second adapter 40 and the electrode plate 50 are normal, the handshaking signals from the electric field generator 10 can finally reach the handshaking chip 54 of the electrode plate 50, and the handshaking state of the handshaking chip 54 can be fed back to the electric field generator 10. If at least one of the connection between the electric field generator 10 and the first adaptor 60, between the first adaptor 60 and the second adaptor 40, and between the second adaptor 40 and the electrode plate 50 is abnormal, the handshaking chip 54 cannot be connected with VCC and GND to form a loop, so that the second adaptor 40, the first adaptor 60, and the electric field generator 10 receive a handshaking state of null signal, and the handshaking fails.

In step 109, the electric field generator 10 of the electric field tumor therapy system 1000 sets the electric field parameters and then proceeds to step 110. The electric field parameters include the frequency, amplitude, etc. of the alternating electrical signal.

In step 110, after the first adaptor 60 sends a temperature reading request to the 2 second adaptors 40 corresponding to the first connector 25-Y1 and the first connector 25-Y2, the temperature signals are read to acquire the temperatures corresponding to the 40 temperature sensors 53 on the electrode pads 50Y1 and 50Y2. Step 111 is entered.

In step 111, the tumor electric field treatment system 1000 determines the type of the electrode sheets 50Y1 and 50Y2 according to the temperature signal, and then proceeds to step 112. The types of the electrode sheets 50Y1, 50Y2 are determined, and the number of the electrode sheet units 51 and the temperature sensors 53 of the electrode sheets 50Y1, 50Y2 is determined. This determination may occur in the second adaptor 40, the first adaptor 60, or the electric field generator 10. In the example shown in fig. 1, 50Y1 and 50Y2 are both determined as the C-shaped electrode sheet 50. The C-shaped electrode sheet 50 has 20 temperature sensors 53, and thus the C-shaped electrode sheet 50 contains 20 effective temperature signals, and 50Y1 and 50Y2 have 40 effective temperature signals.

In step 112, the tumor electric field therapy system 1000 determines whether any one of the 40 effective temperature signals collected by the second adaptor 40 is abnormal, and if so, the process goes to step 114. If all the 40 valid temperature signals are normal, go to step 113.

In step 113, the electric field generator 10 turns on the alternating electric signals Y1, Y2, turns off the alternating electric signals X1, X2 and proceeds to step 115.

In step 114, the tumor electric field treatment system 1000 alarms abnormally due to the effective temperature signals of the electrode plates 50Y1 and 50Y2, and then immediately proceeds to step 120.

In step 115, after the first adaptor 60 sends a temperature reading request to the 2 second adaptors 40 corresponding to the first connectors 25-X1 and the first connectors 25-X2, the temperature signals are read to acquire the temperatures corresponding to all the temperature sensors 53 on the electrode plates 50X1 and 50X 2. Step 116 is entered.

The above steps 110 and 115 are the same for the second adaptor 40, and the specific flow of steps 110 and 115 in the second adaptor 40 can refer to the flow 200.

In step 116, the tumor electric field therapy system 1000 determines the type of the electrode sheet 50X1 or 50X2 from the temperature signal, and then proceeds to step 117. This determination may occur in the second adaptor 40, the first adaptor 60, or the electric field generator 10. In the example shown in fig. 1, 50X1 and 50X2 are both determined as the C-shaped electrode sheet 50. The C-type electrode plate 50 has 20 temperature sensors 53, so the C-type electrode plate 50 contains 20 effective temperature signals, and 50X1 and 50X2 contain 40 effective temperature signals.

In step 117, the tumor electric field therapy system 1000 determines whether any one of the 40 effective temperature signals collected by the second adaptor 40 is abnormal, and if so, the process goes to step 114. If all 40 valid temperature signals are normal, go to step 118.

In step 118, the electric field generator 10 turns on the alternating electric signals X1, X2, turns off the alternating electric signals Y1, Y2 and proceeds to step 119. The total time from step 113, step 115, step 116, step 117 to step 118 is fixed, and the total time is 1s.

In step 119, the tumor electric field treatment system 1000 detects whether an electric field closing command sent by the user is received, and if so, proceeds to step 120; if the electric field closing command is not detected, step 121 is entered.

In step 120, the electric field of the electric tumor therapy system 1000 is turned off and the process proceeds to step 102. At which point the e-field treatment is finished waiting for the next on-field command.

In step 121, the tumor electric field treatment system 1000 determines whether the electric field parameters need to be adjusted according to the current electric field amplitude and the collected temperature signal, and if the electric field parameters need to be adjusted, the process goes to step 109; if the electric field parameters do not need to be adjusted, the process goes to step 110 to step 119 for circulation. The total time of step 118, step 119, step 121, step 110, step 111, step 112 to step 113 is fixed, and in the embodiment is 1s, so that the tumor electric field treatment system 1000 can realize the continuous output of the alternating electric signals in the X1 and X2 directions and the alternating electric signals in the Y1 and Y2 directions, which alternate with the period of 2 s. Meanwhile, the tumor electric field treatment system 1000 can reduce the time interval between the closing of the alternating electric signals X1 and X2 and the opening of the alternating electric signals Y1 and Y2 to 0s; the time interval between the closing of the alternating electric signals Y1 and Y2 and the opening of the alternating electric signals X1 and X2 is reduced to 0s, and the electric field treatment efficiency is improved on the premise of ensuring the temperature acquisition accuracy.

The temperature acquisition process 200 is shown in fig. 6, and the process can be applied to any temperature acquisition process of the second adaptor 40 adapted to the electrode pads 50X1, 50X2, 50Y1, 50Y2, where the second adaptor 40 connected to 50X1 is taken as an example.

In step 201, the second adaptor 40 is connected to the electrode sheet 50X1 and the first connector 60. Step 202 is entered.

In step 202, the second adaptor 40 determines whether a temperature reading request sent by the first adaptor 60 is received, and if the temperature reading request is received, step 204 is performed; if no temperature read request is received, step 202 is repeated.

In step 204, the first controller 45 of the second adaptor 40 controls the switch unit 44 to electrically connect the No. 1 wire of the second connector 31 to the GND of the second adaptor 40 and disconnect the No. 2, 3, and 4 wires (disconnect the No. 2, 3, and 4 wires from the GND). At this time, 5 temperature sensors 53 numbered 1 to 5 on the electrode sheet 50X1 are electrically connected to the resistor group 43 and GND, and 15 temperature sensors 53 numbered 6 to 20 are not electrically conducted.

In step 205, the ADC sampling unit 46 collects the temperature signals corresponding to the temperature sensors 53 coded as 1-5 on the filtered electrode slice 50X 1. The ADC sampling unit 46 collects the conductive analog temperature signals detected by the 5 temperature sensors 53 numbered 1 to 5 on the electrode slice 50X1 after filtering in the order of the sampling channels 1 to 5 and converts the signals into digital temperature signals, and then the process proceeds to step 206. During the time period for acquiring the temperature, the alternating electrical signal emitted by the electric field generator 10 is electrically connected to Y1, Y2, in the embodiment the voltage amplitude between Y1, Y2 is typically greater than 100Vpp. The alternating electrical signal generated by the electric field generator 10 is now electrically disconnected from X1, X2, but since the devices controlling the switching of the alternating electrical signal usually have certain parasitic parameters, when the alternating electrical signal is applied and X1, X2 are disconnected, X1, X2 still have a certain voltage amplitude, which in the example shown in fig. 1 is usually greater than 4Vpp. At this time, the residual alternating electrical signal between X1 and X2 is coupled to each module and conductive trace inside the second adaptor 40, which affects the temperature acquisition of the second adaptor 40 and generates a certain error, so that the filtering module 47 is required to attenuate the medium-high frequency signal in the analog temperature signal detected by the corresponding temperature sensor 53, and then the attenuated medium-high frequency signal is converted into a more accurate digital temperature signal by the ADC sampling unit 46.

In step 206, the first controller 45 of the second adaptor 40 controls the switch unit 44 to electrically connect the No. 2 wire of the second connector 31 to the GND of the second adaptor 40 and disconnect the No. 1, 3, and 4 wires (disconnect the No. 1, 3, and 4 wires from the GND). At this time, 5 temperature sensors 53 numbered 6 to 10 on the electrode sheet 50X1 are electrically connected to the resistor group 43 and GND, and 15 temperature sensors 53 numbered 1 to 5 and coded 11 to 20 are not electrically conducted. Step 207 is entered.

In step 207, the ADC sampling unit 46 collects the temperature signals corresponding to the temperature sensors 53 coded as 6-10 on the filtered electrode slice 50X 1. The ADC sampling unit 46 collects the conductive analog temperature signals detected by the 5 temperature sensors 53 numbered 6 to 10 on the electrode slice 50X1 after filtering in the order of the sampling channels 1 to 5 and converts the signals into digital temperature signals, and then the process proceeds to step 208.

In step 208, the first controller 45 of the second adaptor 40 controls the switching unit 44 to electrically connect the No. 3 wire of the second connector 31 to GND in the second adaptor 40 and disconnect the No. 1, 2, and 4 wires (disconnect the No. 1, 2, and 4 wires from GND). At this time, 5 temperature sensors 53 numbered 11 to 15 on the electrode sheet 50X1 are electrically connected to the resistor group 43 and GND, and 15 temperature sensors 53 numbered 1 to 10 and 16 to 20 are not electrically conducted. Step 209 is entered.

In step 209, the ADC sampling unit 46 collects the temperature signals corresponding to the temperature sensors 53 coded as 11-15 on the filtered electrode slice 50X 1. The ADC sampling unit 46 collects the conductive analog temperature signals detected by the 5 temperature sensors 53 numbered 11-15 on the electrode slice 50X1 after filtering in the order of the sampling channels 1-5 and converts the signals into digital temperature signals, and then the process proceeds to step 210.

In step 210, the first controller 45 of the second adaptor 40 controls the switch unit 44 to electrically connect the No. 4 wire in the second connector 31 to the GND in the second adaptor 40, and disconnect the No. 1, 2, and 3 wires (disconnect the No. 1, 2, and 3 wires from the GND). At this time, 5 temperature sensors 53 numbered 16 to 20 on the electrode sheet 50X1 are electrically connected to the resistor group 43 and GND, and 15 temperature sensors 53 numbered 1 to 15 are not electrically conducted. Step 211 is entered.

In step 211, the ADC sampling unit 46 collects temperature signals corresponding to the temperature sensors 53 encoded as 16-20 on the filtered electrode slice 50X 1. The ADC sampling unit 46 collects the conductive analog temperature signals detected by the 5 temperature sensors 53 encoded as 16-20 on the electrode slice 50X1 after filtering in the order of the sampling channels 1-5 and converts the signals into digital temperature signals, and then proceeds to step 212.

In step 212, the second adaptor 40 finishes the temperature acquisition, and the first controller 45 sends a temperature signal to the first adaptor 60 through the first communication unit 42 and then proceeds to step 202. The temperature signal in this step is a digital temperature signal converted by the ADC sampling unit 46. Alternatively, the transmitted temperature signal may include information about the type of the electrode sheet 50X 1.

In some embodiments, as shown in fig. 7, the electrode sheet 50 is a B-type electrode sheet 50 having 13 electrode units 51; as shown in fig. 8, the electrode sheet 50 is an a-type electrode sheet 50 having 9 electrode units 51.

In the example of fig. 1, the electrode sheets 50X1, 50X2, 50Y1, and 50Y2 may be used in any combination from a-type, B-type, and C-type electrode sheets 50. For example, B-type electrode sheets 50 are used for 50X1 and 50X2, and C-type electrode sheets 50 are used for 50Y1 and 50Y2.

The temperature acquisition process 200 for the B-type electrode plate 50 in this embodiment is the same as the process for the C-type electrode plate 50 in embodiment 1, but in step 209 of the temperature acquisition process 200, the analog temperature signals acquired by the sampling channels 4 and 5 of the ADC sampling unit 46 are close to the analog signals of the VCC power supply voltage value, because No. 4, 5, 9, or 10 wires on the electrode plate 50 electrically connected to the sampling channels 4 and 5 are electrically connected to GND. Similarly, in step 211 of the temperature acquisition process 200, the analog temperature signals acquired by the sampling channels 1 to 5 of the ADC sampling unit 46 are all close to the analog signal of the VCC power supply voltage value, because the wires 1 to 13 on the electrode plate 50 electrically connected to the sampling channels 1 to 5 are not electrically connected to the GND. Therefore, in step 212, the temperature signal transmitted by the second adaptor 40 includes digital temperature signals corresponding to 13 temperature sensors 53 of 1-13 on the electrode slice 50 and digital temperature signals converted from analog signals close to the VCC supply voltage value of 7 non-provided temperature sensors 53 of 14-20. These 7 digital temperature signals, converted from analog signals close to the value of the VCC supply voltage, are the interference temperature data.

The process 100 of the tumor electric field treatment system 1000 for the B-type electrode plate 50 in this embodiment is the same as the process for the C-type electrode plate 50 shown in fig. 1. Taking the B-type electrode plate 50X1 as an example, in step 116, the analog temperature signals corresponding to 7 non-installed temperature sensors 53 numbered 14-20 in the temperature signals are all close to the analog signal of the VCC power supply voltage value. The first adapter 60 can determine that 50X1 is the B-type electrode plate according to the above. Alternatively, the determination process may occur in the second adaptor 40. When processing the temperature signals, the tumor electric field treatment system 1000 can eliminate the temperature signals corresponding to 7 non-temperature sensors 53 with numbers of 14-20 and then perform data processing. For example, in a system in which the B-type electrode sheet 50 is used for the electrode sheets 50X1 and 50X2, and the C-type electrode sheet 50 is used for the electrode sheets 50Y1 and 50Y2, the tumor electric field treatment system 1000 may determine that the electrode sheets 50Y1 and 50Y2 are both the C-type electrode sheets 50 in step 111, 40 temperature signals are effective temperature data, and determine whether there is an abnormality in the 40 effective temperature data in step 112; in step 116, it is determined that both of the electrode sheets 50X1 and 50X2 are B-type electrode sheets 50, and therefore, the temperature signals of 13 temperature sensors 53, which are numbered 1 to 13, respectively, corresponding to the electrode sheets 50X1 and 50X2 are effective temperature data, and the electrode sheets 50X1 and 50X2 have 26 effective temperature data, and it is determined whether there is an abnormality in step 117 for the 26 effective temperature data.

The temperature acquisition process 200 for the a-type electrode plate 50 in this embodiment is identical to the process for the C-type electrode plate 50 in embodiment 1, but the analog temperature signal acquired by the sampling channel 5 of the ADC sampling unit 46 in step 207 is close to the analog signal of the VCC supply voltage value, because the No. 10 wire on the electrode plate 50 electrically connected to the sampling channel 5 is not electrically connected to GND. Similarly, in step 209, the analog temperature signals collected by the sampling channels 1 to 5 of the ADC sampling unit 46 are all close to the analog signals of the VCC power supply voltage value, because No. 3, no. 6, no. 7, no. 8, no. 9, no. 10 wires on the electrode plate 50 electrically connected to the sampling channels 1 to 5 are not electrically connected to GND. In step 211, the analog temperature signals collected by the sampling channels 1 to 5 of the ADC sampling unit 46 are all close to the analog signals of the VCC supply voltage value, because No. 6, no. 7, no. 8, no. 9, no. 10 wires on the electrode plate 50 electrically connected to the sampling channels 1 to 5 are not electrically connected to GND. Therefore, in step 212, the temperature signals transmitted by the second adaptor 40 include digital temperature signals corresponding to 9 temperature sensors 53 numbered 1-9 on the electrode pad 50 and digital temperature signals corresponding to 11 non-set temperature sensors 53 numbered 10-20 converted from analog signals close to the VCC power supply voltage value.

The process 100 of the tumor electric field treatment system 1000 for the a-type electrode plate 50 in this embodiment is the same as the process for the C-type electrode plate 50 in embodiment 1. Taking the a-type electrode plate 50X1 as an example, the analog temperature signals corresponding to 11 non-installed temperature sensors 53 numbered 10-20 in the temperature signals in step 116 are all close to the analog signal of the VCC power supply voltage value. The first adaptor 60 can determine that 50X1 is the a-type electrode plate according to the above. Alternatively, the determination process may occur in the second adaptor 40. When processing the signals, the tumor electric field treatment system 1000 can eliminate the temperature signals corresponding to the numbers 10-20 and then process the signals. For example, for a system using the a-type electrode slice 50 for 50X1 and 50X2 and the C-type electrode slice 50 for 50Y1 and 50Y2, the tumor electric field treatment system 1000 may determine that 50Y1 and 50Y2 are both the C-type electrode slices 50 in step 111, 40 temperature signals are both effective temperature data, and determine whether there is an abnormality in 40 effective temperature data in step 112; since it is determined in step 116 that both 50X1 and 50X2 are the a-type electrode sheet 50, the temperature signals of channels 1 to 9 corresponding to 50X1 and 50X2 are effective temperature data, which is 18 effective temperature data, and it is determined in step 117 whether there is an abnormality in the 18 effective temperature data.

Thus, the a-type, B-type and C-type electrode plates 50 can be combined without changing the flow of the electric field generator 10, the first adapter 60, the second adapter 40 and the tumor electric field treatment system 1000, and the electric field treatment efficiency can be improved without affecting the flexibility of the electrode cables.
