and S104, in the whole process, the steps S101 to S103 are carried out in a circulating mode all the time, meanwhile, the PLC displays monitoring data (such as upstream water level, downstream flood discharge flow rate and opening degree of a flood gate) on a human-computer interface touch screen in real time, and information about whether fault monitoring points of all parts operate normally is displayed through operating fault monitoring indicating lamps.
4. The preset control algorithm in the PLC controller according to claim 3, wherein: according to the upstream actual monitoring water level h and the safe water level h0dividing the opening of the hydraulic opening and closing machine into three safety levels, and then according to the actual monitoring water flow velocity v and the optimal water flow velocity v of the downstream flood discharge0And (4) fine adjustment is carried out, and the specific safety level, the applicable condition, the control algorithm and the opening height and the state of the flood gate are shown in the following table.
Wherein:
h-upstream monitoring the actual water level;
h0the safe level of the station, i.e. the optimal level at which the upstream water level is below the safety warning line and the water storage capacity is reasonable;
h1-a water level of vigilance at a safety level of level 1, determined by the station on the basis of long-term observed practical conditions;
h2-a water level of vigilance at a safety level of level 2, determined by the station on the basis of long-term observed actual conditions;
k-opening value of the hydraulic hoist, called opening for short;
h-actual opening height of the flood gate;
H0-the maximum height of opening of the floodgate;
alpha-opening factor, actual monitored water flow rate v and optimal water flow rate v from downstream flood discharge0Determining;
the K' -opening correction value is related to local climatic conditions, including temperature, humidity, wind, sunshine time, rainfall and other related factors;
v-actual monitored water flow rate for downstream flood discharge;
v0optimum water flow rate for downstream flood discharge, based on long-term observations by the stationdetermining the actual situation of the system;
In addition, the safety level h of the station01-level warning water level h1And 2-level warning water level h2the relationship of (1) is: h is0<h1<h2；
the opening coefficient alpha is determined by the actual monitored water flow velocity v and the optimal water flow velocity v of the downstream flood discharge0Determining, specifically:
(1) when v is less than or equal to v0when α is 1;
(2) When v is>v0When the temperature of the water is higher than the set temperature,wherein n is the adjustment stage number of the opening coefficient alpha, and is selected according to the amplitude and the rate of the water level change of the local station, and the value is generally 2.
