Specifically, the controller can receive signals sent by the remote controller in a wireless code matching mode, and the servo motor is driven by the driver to further control the contact 2 to clamp or loosen a wiring board to be tested of the high-voltage circuit breaker. More specifically, the positive rotation of the servomotor enables the contact 2 to clamp the board to be tested, and the negative rotation of the servomotor enables the contact 2 to unclamp the board to be tested. Meanwhile, the servo motor can feed back the rotating speed of the servo motor to the controller through the driver, and the controller can also transmit a signal to the remote controller in a wireless code matching mode and feed back the signal to the current state of the device of a tester.

As shown in fig. 3, the embodiment further provides a wiring method for high-altitude circuit breaker testing, which uses the wiring device for high-voltage circuit breaker testing, and includes the following steps:
s10, the servo motor is controlled to rotate by the remote controller, so that the contact 2 clamps the wiring board to be tested;
and S20, measuring the current pressure value applied to the wiring board to be tested by the contact 2 in real time by using the pressure sensor, and stopping the rotation of the servo motor when the current pressure value applied to the wiring board to be tested by the contact 2 reaches a preset pressure value.

s21, calculating the difference value between the preset pressure value and the current pressure value applied to the wiring board to be tested by the contact 2;
and S22, calculating the current voltage duty ratio according to the ratio of the difference value to the preset pressure value, and controlling the servo motor to work according to the current voltage duty ratio until the current pressure value applied to the wiring board to be tested by the contact 2 reaches the preset pressure value, and stopping the rotation of the servo motor.
When the controller receives a stop command from the remote controller, the servo motor is immediately stopped by the driver.
The remote controller sends an instruction to the controller, the controller judges whether the instruction is a clamping instruction, a loosening instruction or a stopping instruction, when the clamping instruction is confirmed, the controller controls the servo motor to rotate forwards through the driver so that the contact 2 contacts the wiring board to be tested, the controller receives a current pressure value measured by the pressure sensor, whether the current pressure value is smaller than a preset pressure value or not is judged, if the current pressure value is not smaller than the preset pressure value, the controller controls the servo motor to stop rotating through the driver, a clamped signal is sent to the remote controller, and the remote controller can start the test work of the high-voltage circuit breaker when receiving the clamped signal. When the current pressure value is not less than the preset pressure value, the controller controls the servo motor to stop rotating through the driver, the phenomenon of locked rotor caused by continuous operation of the servo motor can be prevented after the contact 2 clamps the wiring board to be tested, and the driver or the servo motor can be burnt out due to 6-7 times of current generated during locked rotor of the servo motor.
If the current pressure value is smaller than the preset pressure value, the difference value between the preset pressure value and the current pressure value is calculated, the current voltage duty ratio is calculated according to the difference value, the duty ratio of the driver is adjusted to be the current voltage duty ratio by the controller, the rotating speed of the servo motor is further controlled, the current pressure value is continuously increased to the preset pressure value, the contact pressure of the contact 2 and the wiring board to be detected is prevented from being insufficient, the measured value of the resistance of the conductive loop is larger, and misjudgment is conducted on the health state of the wiring.
After the test is finished, the remote controller sends a release instruction to the controller, and when the controller confirms that the received instruction is the release instruction, the controller controls the servo motor to rotate reversely through the driver so that the contact 2 releases the wiring board to be tested. When the current pressure value measured by the pressure sensor received by the controller is zero, the controller controls the servo motor to stop rotating through the driver and sends a loosening signal to the remote controller.
If an emergency exists in the test process, the remote controller sends a stop instruction to the controller, and when the controller confirms that the received instruction is the stop instruction, the controller controls the servo motor to stop rotating through the driver.
