Embodiment Construction

[0044] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0045] Such as figure 1 An intelligent control method for a canal gate includes the following steps:

[0046] Collect water level, flow and gate signals, and transmit them through wireless transmission and wired transmission.

[0047] The water level signal includes the water level signal in front of the gate, the water level signal behind the gate and the water level signal in the middle reaches, and the flow signal is the flow signal behind the gate, which is transmitted wirelessly. Wireless transmission methods include short-distance ZigBee transmission and GPRS long-distance transmission.

[0048] The gate signal includes a gate limit switch signal and a gate opening signal, which are transmitted by wire.

[0049] According to the intelligent control method based on fuzzy neural network and feedforward control, the relationship betwe...

Abstract

The invention discloses a canal system gate intelligent control method and device. The method specifically includes collecting water level, flow and gate signals, and communicating with a control module in a wireless transmission mode and a wired mode, the water level signals including a before-gate water level signal, a behind-gate water level signal and a midstream water level signal, and the flow signal being an behind-gate flow signal; and an intelligent control module processes a water level, flow and gate opening relation according to the intelligent control method based on a fuzzy neural network and feedforward control, and outputs a gate opening control signal to control the gate opening. The canal system gate intelligent control device provided by the invention is adopted to be combined with the control method to realize control of the canal system gate and water level flow, thereby meeting irrigation area water demand.

Description

technical field [0001] The invention relates to the technical field of electric gate monitoring in the water conservancy industry, in particular to an automatic control method and device for a canal system gate. Background technique [0002] The irrigation channel system is an important water conservancy facility, which plays an important role in water transfer and transfer for agricultural production. The canal system is usually divided into multiple canal sections connected in series by multi-level gates. In order to regulate the water volume of each canal section in a reasonable and orderly manner, each canal section uses the opening and closing of the gates to adjust the water level and flow. The automatic control of canal system gates is an important manifestation of the modernization level of the irrigation area. By obtaining the water level and flow information of the irrigation area in real time to operate the canal system gates, the precise control of water level an...
