The Develop Of Multi-agreement Hydraulic Pressure Support Monitor Meter Online

With " high yield high production " mining technology application, hydraulic support to play a bigger role in the hydraulic support various properties of the fully-mechanized face increasingly significant influence efficiency of hydraulic support, so the real-time monitoring is particularly important. But other factors, such as the system reliability, maintainability and related technologies are directly related to the performance of the system. Therefore, in order to realize high mining technique, "the monitoring system of hydraulic support high requirements, it is proposed to satisfy the need of overall coal system. China hydraulic support's monitoring technology along with the development of mining technology, and the 1980s than ~ 1990s had great progress, now also used, but compared with the similar foreign advanced technology, the gap is very obvious. Based on the status quo of hydraulic support technology at home and abroad, China mining face from the conditions, and developed various agreement for the transfer of hydraulic support online monitoring, and strive to meet the need of coal working conditions in China, and accelerate the development of our coal mining technology.The main content of this paper studies is based on the agreement of on-line monitoring system of hydraulic support to solve transmission protocols for different sensors measured data acquisition, data processing and data sampling and analysis on the problem to the console.Based on on-line monitoring system of hydraulic support made a in-depth analysis and research. It firstly introduces the present situation of online monitoring of hydraulic support at home and abroad, this paper expounds the technical level. Secondly, introduces the working of hydraulic support by the pressure Angle and the displacement, monitoring technology. Then, according to the working condition of hydraulic support's monitoring, formed a monitoring system. Finally, A deep research on the structure of the system of hydraulic support for deec interface design, through the sensor interface design, interface design, and 485 completed the work of hydraulic support data acquisition, A/D sampling and processing of data uploaded to the console.
