Automatic dispatch control system and method of salty prevention pumping station

Abstract

The invention discloses an automatic dispatch control system and a method of a salty prevention pumping station, wherein the system is composed of a real-time monitoring unit, a salinity forecasting unit, a central control chamber and an actuating mechanism and the like; the real-time monitoring unit is composed of a plurality of groups of river surface monitors, a reservoir liquidometer, a gate salinity meter and a plurality of GPRS (General Packet Radio Service) modules; the salinity forecasting unit is composed of a first computer and a fourth GPRS module, which are connected through an RS232 serial port bus, the central control chamber is composed of a second computer and a fifth GPRS module, which are connected through an RS232 serial port bus, and the actuating mechanism is composed of a gate, a plurality of water pumps and a plurality of PLCs (Programmable Logic Controller); and the automatic dispatch control system disclosed by the invention can be used for effectively avoiding the salt water from entering water works and guaranteeing the chlorosity of the water of the water works to be minimum under the harsh condition of low water combined with spring tide.

Description

technical field [0001] The invention relates to a control method for automatic scheduling of a salt-avoiding pumping station, in particular to a fully automatic pumping station control system and method based on three major conditions and supplemented by other real-time monitoring data. Background technique [0002] The area affected by tides has always been the area with the densest concentration of human beings and the most developed economy and culture. The impact of salt tide intrusion on urban drinking water is very significant, directly restricting the development of economy and people's livelihood construction. [0003] The phenomenon of the inconsistency of the salinity (chlorinity) along the estuary is called saline tide intrusion, when the fresh water discharged from the river mixes with the salt water flowing upward from the high tide. Affected by the intrusion of salt tide, the change of chlorine in the estuary section can reach 2-10 times. At present, the situ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a control system and method for automatic dispatching of salt-avoiding pumping stations in view of the deficiencies of the prior art. The water enters the water plant, and can ensure the lowest chlorine content of the water plant's incoming water under the harsh conditions of dry water and spring tide combination, which is safe and reliable, and solves the problem of low efficiency, high blindness, and hysteresis of the existing water conservancy control system. strong question
