The Research On Gate's Open Degree And Load Value Measure And Control Monitor

As the core part of water conservancy system, it becomes much important to achieve the digital, intelligence and automation of the gate. With the development of auto-control, telecommunication and computer technology, it has applied remote control and measurement, telecommunication and computer technology on the measurement, calculation, control and adjustment of the gate's and water level's parameter in order to attain the main content and aim of this gate monitor system.The gate's open degree monitor is an intelligent instrument mainly used in scene measuring, gate's open degree and load controlling. The traditional gate's open degree monitor is bad in measurement's accuracy and dependability. What's more, it is common to measure and monitor the load and open degree separately. Carefully consider the practical requirement,.this monitor was designed on the basis of deliberate analysis of the current same production in use. According to requirement of clients, this monitor can be used in various scale water-electricity station for its' flexible, wide adaptation and high automotive degree.This gate's open degree monitor is a system mainly bases on AT89C52,with the help of software of C. Through calculation of the open degree signal and load signal of the sensor, signal judging and treating, communication between people and system by key, this system can display the state of open degree and load. It can alert when there are some problems, drive " relay work, control and manage the various parameters of this monitor through key and LCD. It can also communicate with PC by 485 bus. This self design agreement assured the accuracy and security of this communication. It has a perfect redundant degree and man-machine interface which is more intelligent than before.With the adjustment in laboratory and scene, the result indicate: this design is reasonable and reliable. It has been made into production.
