As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In order to solve the problem of poor interference resistance of the conventional high-voltage electric pulse tumor treatment apparatus, in one embodiment, referring to fig. 1, there is provided a control circuit applied to the high-voltage electric pulse tumor treatment apparatus, including:
a controller 11 for generating and outputting pulse parameters; the pulse parameters comprise pulse period, pulse width and pulse number;
the signal output circuit 13 is used for generating and outputting a pulse signal according to the pulse parameter when the pulse parameter is smaller than a preset safety threshold;
and the photoelectric isolation circuit 15 is used for performing photoelectric isolation processing on the pulse signals and transmitting the pulse signals subjected to the photoelectric isolation processing to a pulse generating circuit of the high-voltage electric pulse tumor therapeutic apparatus.
It should be noted that, a user inputs an instruction to the controller according to actual needs, and the controller generates corresponding pulse parameters according to the instruction. The controller generates pulse parameters and writes the pulse parameters into the signal output circuit. The pulse parameters are used to characterize the pulse signal, which includes the pulse period, pulse width, and number of pulses. In one example, the controller includes a Central Processing Unit (CPU) module, which is connected to the signal output circuit.
The signal output circuit is internally provided with a preset safety threshold in advance, after the pulse parameter is written in by the controller, the signal output circuit judges whether the pulse parameter is smaller than the preset safety threshold, and if the pulse parameter is smaller than the preset safety threshold, the signal output circuit generates a pulse signal according to the pulse parameter, so that the safety of pulse signal output is improved, and the safety of the controller for generating and outputting the pulse signal is improved. In one example, the signal output circuit may be a programmable logic or a processor, or other device for generating a pulse signal. Before generating the pulse signal, the signal output circuit needs to judge whether the pulse period of the pulse parameter is smaller than the preset pulse period, whether the pulse width of the pulse parameter is smaller than the preset pulse width and whether the pulse number of the pulse parameter is smaller than the preset pulse number, and if the pulse period of the pulse parameter is smaller than the preset pulse period, the pulse width of the pulse parameter is smaller than the preset pulse width and the pulse number of the pulse parameter is smaller than the preset pulse number, the signal output circuit generates the pulse signal according to the pulse parameter. In one example, a preset safety threshold may be configured in the controller, and the controller determines whether the pulse parameter is smaller than the preset safety threshold after generating the pulse parameter according to an instruction input by a user, and writes the pulse parameter into the signal output circuit if the pulse parameter is smaller than the preset safety threshold. In one example, the signal output circuit is a digital signal output circuit.
To further enhance the immunity to interference of the pulse signal and the accuracy of outputting the pulse signal, in one example, the signal output circuit is configured to output a high level when no pulse signal is output.
The photoelectric isolation circuit receives the pulse signal sent by the signal output circuit, converts the pulse signal into an optical signal, converts the optical signal into the pulse signal during output and transmits the pulse signal to the pulse generating circuit of the high-voltage electric pulse tumor therapeutic apparatus, namely the pulse signal is subjected to photoelectric isolation processing and then transmitted to the pulse generating circuit of the high-voltage electric pulse tumor therapeutic apparatus, so that the pulse signal is isolated, and the anti-interference performance in the pulse signal transmission process is improved. Specifically, the signal output circuit transmits the generated pulse signal to the pulse generating circuit.
In various embodiments of the control circuit of the present application, the control circuit includes: the controller is used for generating and outputting pulse parameters; the pulse parameters comprise pulse period, pulse width and pulse number; the signal output circuit is used for generating and outputting a pulse signal according to the pulse parameter when the pulse parameter is smaller than a preset safety threshold value; the photoelectric isolation circuit is used for carrying out photoelectric isolation processing on the pulse signals and transmitting the pulse signals subjected to the photoelectric isolation processing to the pulse generating circuit of the high-voltage electric pulse tumor therapeutic apparatus, so that the interference propagation path of the pulse signals is isolated, the anti-interference performance of the pulse signals is enhanced, the accuracy of the pulse signals is improved, and the anti-interference capacity of the tumor therapeutic apparatus is further improved.

In order to enhance the anti-interference performance of various signals sent by the controller and various signals received by the controller in the high-voltage environment in the high-voltage electric pulse tumor therapeutic apparatus and improve the accuracy of signal transmission, in one example, the Buffer module is further used for amplifying the power of the control signal sent by the controller and transmitting the amplified control signal to the photoelectric isolation circuit;

It should be noted that, in order to ensure that each controlled module of the high-voltage electric pulse tumor therapeutic apparatus can operate in a coordinated and ordered manner, the controller sends a control signal to each controlled module to instruct each controlled module to execute a corresponding action according to the control signal. In order to improve the anti-interference performance of the control signal, the control signal is subjected to power amplification processing through a Buffer module, and then subjected to photoelectric isolation processing through a photoelectric isolation circuit and transmitted to a controlled module. The control signal comprises a charging control signal, a Pulse Width Modulation (PWM) wave control signal and/or a discharging control signal, wherein the charging control signal is transmitted to the charging circuit to instruct the charging circuit to start or stop charging; transmitting the PWM wave control signal to a power supply system to indicate the power supply system to output corresponding voltage; the discharge control signal is transmitted to the discharge circuit to instruct the discharge circuit to start or stop discharging.

and the controller is also used for identifying the running state of the controlled module according to the analog signal.
It should be noted that, in addition to controlling each controlled module, the controller also monitors the operation state of each controlled module, so as to ensure the safe and stable operation of the controlled module. In order to improve the anti-interference performance of the analog signal, each controlled module feeds back the analog signal to the controller through the photoelectric isolation circuit, the controller identifies the running state of the controlled module according to the analog signal, for example, the charging circuit feeds back the analog signal to the controller through the photoelectric isolation circuit, and the controller can identify whether the charging circuit is fully charged or not, whether the charging circuit is currently in the charging state or not according to the analog signal; the pulse generating circuit feeds back an analog signal to the controller through the photoelectric isolation circuit, and the controller identifies whether the pulse generating circuit can normally generate a pulse signal, parameters of the pulse signal and the like according to the analog signal; the discharge circuit feeds back an analog signal to the controller through the photoelectric isolation circuit, and the controller identifies the discharge voltage, the discharge needle channel and the like of the discharge circuit according to the analog signal.

The controller further includes an expansion interface, which is capable of expanding and connecting external devices, for example, the external devices include a foot switch, an electrocardiograph monitor, and the like, so that the controller realizes unified monitoring of the devices in the expansion connection. In order to improve the anti-interference performance of the level signal, each external device feeds back the level signal to the controller through the photoelectric isolation circuit and the Buffer module, the controller identifies the running state of the external device according to the level signal, for example, the foot switch feeds back the level signal to the controller through the photoelectric isolation circuit and the Buffer module, the controller identifies the open state, the closed state and the like of the foot switch according to the level signal, and if the foot switch is identified to be in the closed state, the power supply system is controlled to supply power to the high-voltage electric pulse tumor therapeutic apparatus, and the operation is started; if the high-voltage electric pulse tumor therapeutic apparatus is in the off state, the power supply system is controlled to stop supplying power to the high-voltage electric pulse tumor therapeutic apparatus, and the high-voltage electric pulse tumor therapeutic apparatus stops working. The Buffer module is used for buffering the level signal and carrying out level conversion, so that the level signal passing through the photoelectric isolation circuit can be level-matched with the controller and the signal output circuit, and the controller and the signal output circuit are protected, and meanwhile, level identification monitoring can be accurately carried out.
In one example, the Buffer module is further configured to perform power amplification processing on a signal sent by the controller, and transmit the signal after power amplification to the optoelectronic isolation circuit;
the photoelectric isolation circuit is also used for carrying out photoelectric isolation processing on the signals and transmitting the signals after the photoelectric isolation processing to external computer equipment.
