That is, each device related to the present embodiment can be realized by a conventional hardware structure.
For ease of understanding, the alarm principles for each situation are described in detail below.
1. The motor of the hydraulic station 1 is controlled to start and stop.

The PLC controller 10 is provided with a pressure value at which the motor is started and a pressure value at which the motor is stopped.
When the hydraulic pressure data is lower than the pressure value for starting the motor, the pressure of the hydraulic station 1 is lower, the motor needs to be started for pressure compensation, the PLC 10 supplies power to the AC contactor 11, the AC contactor 11 is closed, the power supply of the motor is switched on, and the motor is started to work; when the hydraulic pressure data is higher than the pressure value at which the motor stops, it is described that the pressure of the hydraulic station 1 is relatively high, and the motor needs to be stopped, the PLC controller 10 stops supplying power to the ac contactor 11, the ac contactor 11 is turned off, and the motor stops operating.
2. The high-pressure and low-pressure alarm of the hydraulic station 1 is realized.
The PLC controller 10 is provided with a pressure value for high pressure alarm and a pressure value for low pressure alarm.
When the hydraulic pressure data is higher than the pressure value of the high-pressure alarm, which indicates that the pressure of the hydraulic station 1 is too high, the high-pressure alarm needs to be performed, the PLC 10 supplies power to an indicator lamp HL1 in the fault alarm lamp 12, and the alarm 13 gives an alarm; when the hydraulic pressure data is lower than the pressure value of the low-pressure alarm, which indicates that the pressure of the hydraulic station 1 is too low, the low-pressure alarm needs to be performed, the PLC 10 supplies power to an indicator lamp HL2 in the fault alarm lamp 12, and the alarm 13 gives an alarm.

Otherwise, the liquid level relay 6 is disconnected, and the PLC 10 stops supplying power to the indicator lamp HL3 and gives an alarm to the alarm 13.
4. The alarm (oil alarm) that the oil quality of the hydraulic station 1 is more in impurity is realized.
The oil return filter 7 is used for acquiring oil quality information (oil pollution condition) of the hydraulic station 1 and sending the oil quality information to the PLC controller 10 by a switching value signal. When the oil quality information is lower than the set minimum oil quality value (more oil impurities), the oil return filter 7 is closed, and after receiving the oil quality value, the PLC 10 supplies power to an indicator lamp HL4 in the fault alarm lamp 12 and gives an alarm through an alarm 13. Otherwise, the return oil filter 7 is disconnected, the PLC controller 10 stops supplying power to the indicator lamp HL4, and gives an alarm through the alarm 13.

The intermediate relay 8 is used for collecting power supply information of the power supply 3, the power supply 3 is normally AC 380V three-phase power, and each phase needs one intermediate relay 8 and sends the power supply information to the PLC 10 through a switching value signal. The coils of the three intermediate relays 8 are respectively connected with the phase A, the phase B and the phase C of the power supply 3 in parallel, and the normally closed contact of the intermediate relay 8 is connected with the PLC 10. When one or more phases are powered off, the corresponding coil of the intermediate relay 8 is powered off, the normally closed contact is disconnected, and the PLC 10 receives power supply information of the intermediate relay, supplies power to an indicator lamp HL5 in the fault alarm lamp 12 and gives an alarm through an alarm 13. Otherwise, the normally closed contact is connected, and the PLC controller 10 stops supplying power to the indicator lamp HL5 and gives an alarm to the alarm 13.
6. And the alarm (the alarm of the running state of the motor) of the hydraulic station 1 when the working time of the motor is too long is realized.
The time relay 9 is used for collecting the motor working time information of the hydraulic station 1 and sending the motor working time information to the PLC 10 by a switching value signal. The time relay 9 sets the maximum continuous operation time of the motor, and when the motor of the hydraulic station 1 is started, the time relay 9 starts to count time, and when the motor of the hydraulic station 1 is stopped, the time relay 9 stops counting time and clears zero. When the working time collected by the time relay exceeds the set maximum continuous working time, the time relay 9 is closed, after the PLC 10 receives the working time value of the motor, the PLC 10 stops supplying power to the alternating current contactor 11, the power supply of the motor is disconnected and stopped, and meanwhile, the PLC 10 supplies power to an indicator lamp HL6 in the fault alarm lamp 12 and gives an alarm through an alarm 13.
