the control device 130, the control device 130 is respectively connected with the output end of the voltage detection circuit 110 and the output end of the current detection circuit 120; the control device 130 is configured to collect a voltage signal, and generate a first alarm trigger signal when a voltage value of the voltage signal exceeds a voltage threshold; the control device 130 is also used for collecting current signals; when the current value of the current signal exceeds the current threshold range, generating a second alarm trigger signal;
the alarm device 140, the alarm device 140 is connected with the control equipment 130; the alarm device 140 generates an alarm based on the received first alarm trigger signal or second alarm trigger signal.
The voltage detection circuit 110 is used to detect the voltage of the pulse signal output by the pulse generator; for example, the voltage detection circuit 110 may obtain the pulse signal, and perform a conversion process on the pulse signal to obtain a voltage signal corresponding to the pulse signal. The current detection circuit 120 can be used to detect the pulse signal output by the capacitor bank; for example, the current detection circuit 120 may obtain the pulse signal, and perform conversion processing on the obtained pulse signal, so as to obtain a current signal corresponding to the pulse signal. The control device 130 refers to a processing device having functions of signal transmission, signal acquisition processing, and the like. The alarm device 140 may be a flashing light or a buzzer, or may be a combination of a flashing light and a buzzer. The voltage signal may be a pulsed voltage signal; the current signal may be a pulsed current signal; the first alarm trigger signal may be a level signal, such as a high level signal or a low level signal; the second alarm trigger signal may be a level signal, such as a high level signal or a low level signal.
It should be noted that the pulse generator refers to a system for sending signals, and an electric pulse signal instrument for generating required parameters; for example, the pulse generator may be, but is not limited to, a pulse generator of a pulse boost type and a pulse generator of a solid state switch series type.
Specifically, based on that the voltage detection circuit 110 is connected to two ends of the discharge plate, in the process that the pulse generator outputs a pulse signal to the discharge plate, the voltage detection circuit 110 may monitor a voltage signal of the pulse generator and transmit the monitored voltage signal to the control device 130, and then the control device 130 may collect the voltage signal and generate a first alarm trigger signal when a voltage value of the voltage signal exceeds a voltage threshold according to the collected voltage signal; and transmits the generated first alarm trigger signal to the alarm device 140 so that the alarm device 140 generates an alarm according to the received first alarm trigger signal.

In one example, the voltage threshold may be set to 3000V, and the control device 130 generates the first alarm trigger signal when the voltage value of the voltage signal exceeds 3000V; and transmits the generated first alarm trigger signal to the alarm device 140, so that the alarm device 140 generates an alarm according to the received first alarm trigger signal

In one embodiment, the control device is further configured to process the current signal, and according to the processing result, transmit a second alarm trigger signal generated to the alarm device when the current value of the current signal reaches a first overcurrent threshold, and disconnect the pulse generator and the discharge plate of the tumor therapy apparatus when the current value of the current signal reaches a second overcurrent threshold; and the first overcurrent threshold value is smaller than the second overcurrent threshold value.
The pulse generator can be used for controlling and outputting a pulse signal; the discharge plate refers to a channel panel to which the probes are connected.

specifically, the user may preset a range of pulse width thresholds. The control device can process the collected voltage signal (such as measuring the duration time of a high level in the voltage signal), generate a third alarm trigger signal when the pulse width data exceeds the range of the pulse width threshold according to the processing result, and transmit the third alarm trigger signal to the alarm device, so that the alarm device generates an alarm according to the third alarm trigger signal, and a user can conveniently adjust the relevant parameters of the pulse signal in time according to the alarm condition.
For example, the range of the pulse width threshold is set to be 50 microseconds to 120 microseconds, the control device may process the collected voltage signal (for example, measure the duration time of a high level in the voltage signal), and according to the processing result, when the pulse width data exceeds the range of 50 microseconds to 120 microseconds, generate a third alarm trigger signal, and transmit the third alarm trigger signal to the alarm device, so that the alarm device generates an alarm according to the third alarm trigger signal, and a user can adjust the relevant parameters of the pulse signal in time according to the alarm condition.
In one example, when the pulse width data exceeds the range of the pulse width threshold value, the pulse generator and the discharge plate of the tumor therapeutic apparatus can be directly cut off, and when the pulse width of the pulse signal reaches the dangerous threshold value, the source of the output pulse signal is automatically cut off, so that the timeliness of responding to the monitoring parameter response of the tumor therapeutic apparatus is improved, and the safety performance of the tumor therapeutic apparatus is enhanced.
