1、英文原文One Realization Method for Remote Control of Hydraulic Support of the Electro-hydraulic in Coal Mine FaceAbstractThe remote control part of the system can set parameters such as operating mode and so on, while real-time recording and displaying running state of hydraulic supports, preserving his
2、torical data. It gathers control, data recording, data query and intelligence analysis as a whole, communicating with underground with RS485 and CANBUS communication interface functions, through PROFIBUS, MODBUS, CANBUS and other real-time protocols, in order to achieve continuous data acquisition a
3、nd control, namely, to achieve unattended automatic operation, so that unmanned in the major coal production links to attain truly safe production.I. IntroductionSince the inception of mechanized mining technology, all electro-hydraulic control system of hydraulic supports depend on imports. But the
4、 high cost and price, long supply cycle, technological security, untimely service, unopened agreement severely restrict the development of Chinas coal industry, and even become into bottleneck problems of the developing highintensive production to achieve unmanned exploration despite its excellent p
5、erformance and technical support in enhancing the countrys coal production and efficiency. And coal is the main body of Chinas primary energy, accounting for 70% of total energy. National Plan for long-term scientific and technological development explicitly pointed out that we should vigorously dev
6、elop coal clean, efficient, safe mining and utilization technologies, and strive to reach the international advanced level. Around this development strategy, intensive and efficient coal mining equipment and technology, automation and intelligent technology of coal production, coal mine safety produ
7、ction technology has become a priority theme of development in China, and coal integrated mechanization and automation technology are the key link to achieve safe and efficient coal mining, while the hydraulic supports electro-hydraulic automatic control system is an important part of the link. Hydr
8、aulic supports electro-hydraulic control system is a distributed control system. There are these hydraulic support electro-hydraulic control system: DBTs PM4, MARCO companys PM31 and JOYs RS20-type and so on. The first fully mechanized caving hydraulic supports electro-hydraulic control system desig
9、ned by the Coal Science Research Institute (Heaven and Earth Science and Technology Co., Ltd.) and the German Make has been running in Yanzhou Coal Mine. The system represents latest development level of the current electro-hydraulic control system, but the process of localization has not been yet c
10、ompleted. To this end, research for hydraulic supports electrohydraulic automatic control system with independent intellectual property has not only of great practical significance, but also has far-reaching historical significance.Hydraulic supports electro-hydraulic automatic control system is one
11、 network monitoring and control system with local control, LAN control and remote control , including ground control system, central control system, frame controller, network communication systems and power supply. The method resolves the ground control issues of hydraulic supports electro-hydraulic
12、 control system, which is remotecontrolled part and the master part of unmanned watching mining.
