Abstract


Gate as the core institutions of the water systems , digital, intelligent , automation has become very urgent . With the automatic control, communications and computer technology continues to evolve , remote sensing and control , communications and computer technology is applied to the gates and the water level and other parameters of the automatic measurement , control and regulation is the main content and goals of the sluice monitoring system . Gate opening Load Monitor is a site survey, intelligent instrument control gate opening and load . Old-fashioned gate opening measuring instrument measurement accuracy is low , poor reliability , and the majority of our gate control system are the load monitoring and separated from the opening degree of monitoring and control design . In this request , the system is in a serious study on the basis of the advantages and disadvantages of the related products at home and abroad , taking fully into account the needs of users throughout the design process , design a set of flexible , versatile , automated a higher degree of gate opening load Monitor , the design of the product can be used in hydropower plants and water systems of all sizes . Described in this article gate opening load measurement and control instrument based on AT89C52 microcontroller as the core component of the operating system , software programs prepared by the C language support: the opening signal and the load signal from the sensor to the calculation to determine treatment : the man-machine interaction is mainly accomplished by the key ; display gate opening degree of the load state and the alarm in the event of a fault ; drive relays work ; each gate opening monitor parameters through the control and management of keys and character liquid crystal display . ; the system also communications, data transmission and remote monitoring ( PC ) using the 485 bus , relying on self-designed protocols to ensure . Has a good safety redundancy and good man-machine interface , to achieve a higher level of intelligence . After the actual commissioning of the laboratory , the results show that : the overall system design is reasonable , reliable performance , to achieve the desired objectives .
