Coal seam fully-mechanized mining working information system is the system that instrument, relay combine with bussing technique, on hierarchical structure, system can be divided into three layers, wherein the ground monitoring station is top layer, monitoring master station in the underworkings is the intermediate layer, and some outstations that coal-face is installed on the hydraulic support are the bottom.
Coal seam fully-mechanized mining working surface hydraulic support, coal-winning machine, drag conveyor are the cores that automation, unmanned modern fully-mechanized mining working are built, especially the most complicated with the monitoring of hydraulic support, should determine the position of coal-winning machine by hydraulic support, also control simultaneously the stepping of scraper plate machine by hydraulic support, therefore must be core with the monitoring system of hydraulic support, launch R﹠D work.The monitoring of hydraulic support divides station control to finish by work plane, adopts electrical control to replace managing between frame, and work plane divides station control generally to adopt wire communication each other at present.
In the last few years, network technology has obtained develop rapidly, technology is of a great variety, but can be divided into cable technology and wireless technology two big classes generally, wherein wireless technology is owing to have flexible for installation, convenient, do not need characteristics such as complicated wiring and be subjected to people's favor, prospect has a very wide range of applications.
Bluetooth technology is a kind of wireless communication technology, its agreement essence is to set up the standard of general radio interface and control software thereof, make between mobile communication and the network and can realize seamless link, thus, for the portable set of different manufacturers production provides the interoperability passage in the short range.Have advantage low in energy consumption, cost is low simultaneously.The communication distance of bluetooth equipment is 10 meters to 100 meters.Adopt frequency hopping, can resist because the bigger caused signal fadeout of coal dust; Adopt the fast frequency hopping technology, improve the safety of communication; Adopt the forward error correction coding technology, so that the interference of numerous caused random noises of metallic conductor in eliminating transmission medium.Its working frequency range is 2.4GHz, in industry, the science frequency range of regulation, can save the trouble of application-specific license.The Bluetooth technology modulation system is a frequency modulation, and equipment is simple and reliable.Bluetooth technology had both been supported asynchronoud data channel, also supported the simultaneous voice passage, and the highest effective transmission speed of data is 700kbps.
Summary of the invention
The purpose of this utility model is for numerous clients provide that a kind of cost is lower, strong interference immunity, security performance is high and do not need the frequency application to be convenient to the short distance of popularizing, the hydraulic support control appliance based on Bluetooth technology that not influenced by obstruction on a large scale, can control the hydraulic support execution thereby make the coal-face operative employee not need to enter the danger zone.
A kind of hydraulic support control terminal based on wireless communication technology, be made up of front end interface 1, A/D modular converter 2, photoelectricity isolation 3, crystal oscillator 4, register 5, keyboard 6, core single-chip microcomputer 7, liquid crystal display 8, warning device 9, electromagnetic valve group 10, bluetooth module 11, antenna 12, its structure connection layout as shown in Figure 1.Bluetooth module 11 links to each other with the I/O mouth of core single-chip microcomputer, receives and transmission information by antenna 12 simultaneously.Can be by keyboard 6 to core single-chip microcomputer 7 input information, the survey data of relevant devices is isolated 3 input core single-chip microcomputers 7 by front end interface 1 input through A/D modular converter 2 and photoelectricity.Relevant data can show by LCD 8, sets alert equipment 9 warnings of value Times when surpassing.Crystal oscillator 2 links to each other with system clock input X1, the X2 of core single-chip microcomputer 7, for core single-chip microcomputer 7 provides clock signal.Register links to each other with the I/O mouth of core single-chip microcomputer 7, is used to store the data of being gathered.Electromagnetic valve group 10 is connected with external equipment, is used for hydraulic support is controlled.This equipment can be used with hand-held hydraulic bracket controller.
This utility model has following advantage:
1, in working face of coal seam, only need a control terminal just can realize functions such as data acquisition, Industry Control, status poll by wired or wireless mode with adjacent frame or a plurality of hand-held hydraulic bracket controller based on Bluetooth technology;
2, mobility is strong, the position of data acquisition end can be changed within the specific limits, for senior application provides convenience;
3, remove the loaded down with trivial details hardship of wiring from, increase communications security;
4, by the communication distance of bluetooth and authentication etc. determine that its data security is reliable;
5, adopt frequency hopping mode, strong interference immunity;
