[0016] The utility model is provided with a generating module 2 and a sensing module 3 to send signals to the electromyograph 100 and receive signals output by the electromyograph 100 so as to judge the performance of the electromyograph 100 by the sent and received signals. The control module 1 is respectively connected to the generating module 2 and the sensing module 3, and the generating module 2 and the sensing module 3 are respectively connected to the electromyograph 100. The generating module 2 converts the analog electromyographic data output by the control module 1 into electromyographic signals simulating the electrical signals of the human body and inputs the electromyograph 100. The sensing module 3 converts the electrical stimulation signals output by the electromyograph 100 into induced electromyographic stimulation data and inputs the data into the control module 1.

[0017] See also Figure 1 and Figure 2 The generating module 2 includes a digital-to-analog converter 21, a signal voltage reducer 22 and a generating electrode 23. The input end of the digital-to-analog converter 21 is connected to the control module 1. The input end and the output end of the signal voltage reducer 22 are respectively connected to the output end of the digital-to-analog converter 21 and the generating electrode 23. The generating electrode 23 is connected to the recording electrode 101 of the electromyograph 100. The digital-to-analog converter 21 is used to convert analog electromyographic data from a digital signal form into an electromyographic signal in an analog signal form. The generating electrode 23 is used to output the electromyographic signal that has been voltage-reduced by the signal voltage reducer 22, which is conducive to accurately simulating the electrical signals of the human body and facilitating the detection of the electromyograph 100.
[0018] Specifically, in this embodiment, the simulated electromyographic data is typical electromyographic data screened from a large amount of electromyographic data formed by the electromyograph 100 collecting electrical signals of the human body, and the generating module 2 is responsible for converting and restoring this data into classic electromyographic signals that simulate the electrical signals of the human body, but is not limited to this.
[0019] Specifically, in this embodiment, the signal step-down device 22 is a step-down circuit. Since the voltage of the analog electromyographic data is 5V, and the voltage of the electromyographic signal is between 5uV and 50uV, a signal step-down device 22 is required to reduce the voltage of the analog electromyographic data in order to simulate the electromyographic signal, but this is not limited to this.
[0020] See also Figure 1 and Figure 2 The generating electrode 23 includes a ring electrode interface 231, a patch electrode interface 232 and a needle electrode interface 233.

[0024] Optionally, the electrical stimulation signal is a DC signal, the stimulation electrode 102 of the electromyograph 100 includes a first output terminal 1021 and a second output terminal 1022, the sensing electrode 31 includes a positive connection pin 311 and a negative connection pin 312, the positive connection pin 311 is connected to the first output terminal 1021, and the negative connection pin 312 is connected to the second output terminal 1022, which is conducive to accurately receiving the electrical stimulation signal of the electromyograph 100.

The cooperation of the control module 1 with the generating module 2 and the sensing module 3 is conducive to objectively detecting the quality of the electromyograph 100.
[0027] Specifically, in this embodiment, the single-chip microcomputer 11 is responsible for controlling the transmission of data. The single-chip microcomputer 11 receives the induced electromyographic stimulation data output by the sensing module 3 and transmits it to the computer 12 through the data exchange module 13, and the analog electromyographic data of the computer 12 is transmitted to the single-chip microcomputer 11 through the data exchange module 13. The single-chip microcomputer 11 transmits it to the generating module 2 so that the generating module 2 can generate electromyographic signals, but is not limited to this.
[0028] Specifically, in this embodiment, the display module 4 is a display screen on the computer 12, but is not limited thereto.
