If the error is within the range, the PLC controller 18 instructs the winches 71 and 72 to stop operating, and the gates a, B and C are brought into the operating state shown in fig. 13 (this state is the initial state of the gate), so that water can flow through the landscape gate. The first layer of water can be taken. If the first layer of water is taken, the light is darker or at night, the rainbow light 6 appears yellow.

If the error range is not within, a signal is sent to the alarm horn lamp 9 through the signal output end, the alarm horn lamp is turned on, an alarm is sent out, and the remote control end is started again.
