It is required to realize data collection of the surface temperature (unit: ℃), vibration velocity (unit: mm / s) and vibration displacement (unit: μm) of the temperature vibration sensor, and display them correctly on the human-computer interaction interface 210 with correct data units. At the same time, the system performs the following process logic control:

[0052] (1) Manual mode: Switch the conversion switch to the manual position to realize the following functions: Press the start button of pump 1, and pump 1 will continue to rotate counterclockwise; Press the stop or emergency stop button of pump 1 to stop pump 1; Press the start button of pump 2, and pump 2 will continue to rotate counterclockwise; Press the stop or emergency stop button of pump 2 to stop pump 2; the operating indicator lights of pump 1 and pump 2 are consistent with the operating status of the pumps.

[0053] (2) Automatic mode: The water level in the water collection well is divided into four water level values: super high water level (fixed at 20cm), high water level, low water level, and super low water level (fixed at 10cm). The high and low water level values ​​can be set on the human-machine interface 210. Switching the conversion switch to the automatic gear position can achieve the following functions: the manual start and stop buttons of the dual pumps are invalid; pressing the automatic emergency stop button stops the dual pumps. When the water level is lower than the super low water level value, both pumps stop. When the water level is higher than the low water level value, start a single pump. The dual pumps rotate, and the rotation mode is divided into a number rotation mode and a time rotation mode. If the rotation mode on the human-machine interface 210 is a time rotation mode, the pump with the shortest cumulative running time will be started first. The rotation time defaults to 3 seconds. When the rotation time is up, another pump will be switched to run. The rotation time can be set on the human-machine interface 210. If the rotation mode on the human-machine interface 210 is the number rotation mode, the pump with the least cumulative running times will be started first. The default number of rotations is 2 times. When the number of rotations is reached, another pump will be switched to run. The number of rotations can be set on the human-machine interface 210. When the water level is higher than the high water level value, both water pumps are started. The running indicator lights of pump 1 and pump 2 are consistent with the running status of the pumps.

[0054] In another embodiment, for example, scenario training of the gate control system is implemented through programming of the programmable logic controller 310. The gate control system requires the following contents to be valid in the manual and automatic modes: the panel sets the maximum frequency of the inverter to 45Hz and the starting frequency to 10Hz. The communication setting frequency of the gate rising and falling is 20-40Hz and can be modified on the human-machine interface 210, and the acceleration and deceleration time is 0.5-2 seconds and can be modified on the human-machine interface 210.

[0055] The human-machine interface 210 can display the given frequency (unit: Hz), output frequency (unit: Hz), input voltage (unit: V), output voltage (unit: V), mechanical speed (unit: RPM), and bus voltage (unit: V) of the gate inverter.

[0056] (1) Manual mode: Press the gate up button and the gate will continue to rise. Press the gate down button and the gate will continue to fall. Press the gate emergency stop button and the gate will stop.

[0057] (2) Automatic mode: When the water level in the water collection well is higher than the super high water level, the gate will be closed immediately and move down to the fully closed position (15 cm). After the cause of the increase in water inflow to the water collection well is investigated, the water level returns to below the low water level value. Press the gate rise button on the operation box and the gate will automatically rise to the fully open position (25 cm).
