A multi-canal section water conservancy system and its control method

Abstract

The invention discloses a multi-channel water conservancy system. The multi-channel water conservancy system comprises a plurality of gates, data acquisition stations and a terminal upper computer, wherein the data acquisition station is arranged at each channel; the data acquisition station at each channel is used for acquiring hydrologic monitoring information through all hydrologic monitoring sensors in the channel and sending the acquired hydrologic monitoring information to the terminal upper computer and a gate control mechanism of a closest gate at the upstream of the channel respectively. The gate control mechanism calculates the gate according to the received information and controls the opening and closing of the gate. The terminal upper computer is used for carrying out sorted storage on the received hydrologic monitoring information according to a network address and an identification number of each data acquisition station, calculating a practical-operation opening value of the closest gate at the upstream of each channel by a data processing module and sending the practical-operation opening value to an opening and closing machine in the gate control mechanism of the corresponding channel. The multi-channel water conservancy system disclosed by the invention has the advantages that the opening and closing machine in the gate control mechanism is controlled by the terminal upper computer under a normal mode, and under the emergency situation, opening and closing of the corresponding gate are controlled through one or more gate control mechanisms by switching to an emergency mode.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a multi-canal section water conservancy system and a control method provided by the same. Background technique [0002] With the development of economy and society, the contradiction between supply and demand of water resources has become increasingly prominent, and many areas have built long-distance large-scale open channel water delivery projects. These canals are usually divided into multiple canal sections connected in series by multi-level control gates. In order to regulate the water volume of multiple canal sections in a reasonable and orderly manner, each canal section uses the opening and closing of gates to adjust the water level and flow. [0003] In existing canals with multiple sections, automatic gate control methods are divided into two types: upstream control methods and downstream control methods. The former is a traditional control method, which monitors the c...
