The distance setting of each wireless module and principle of work and process are described below among the embodiment of the Precise Position System of the pit gear of the utility model embodiment, and be identical with pinpoint coal mining system.
Be illustrated in figure 2 as the structural representation of the pinpoint coal mining system embodiment of the utility model; Comprise coalcutter, along the hydraulic support that is provided with at interval on the coalcutter moving direction and be installed in coalcutter and hydraulic support on accurate positioning subsystem; Its accurate positioning subsystem as stated; The principle of work and the process of this coal mining system are following: placing 1 fixedly Zigbee wireless module (every hydraulic support is wide 1.5 meters) along every on tens meters to up to a hundred meters of a rows' on the coalcutter moving direction the pit gear hydraulic support at a distance from 3 meters; These wireless module stationkeeping are known; Be called the category-A node, the fixedly Zigbee wireless module of each category-A node all is connected with back level main-machine communication.1 mobile Zigbee wireless module is installed on coalcutter; This module position moves the unknown, is called the category-B node, B node and the air line distance 1-3 rice that leaves its nearest category-A node; Two adjacent category-A nodal distances are 3 meters, and 1 category-A node is installed on promptly per two hydraulic supports.When the B node advances (straight line L) with coalcutter when; Packet is sent in the broadcasting that does not stop; After receiving packet, send information to back level main frame and carry out data processing from its nearer a part of category-A node; Judge from any piece category-A node by a back level main frame according to these category-A node signal intensity levels nearest, thereby judge the advanced positions of coalcutter.
The pinpoint hydraulic support atomizing de-dusting control system of the utility model; Comprise the hydraulic support that is provided with along interval on the coalcutter moving direction and be used to be installed in the accurate positioning subsystem on coalcutter and the hydraulic support; Be equipped with atomizing de-dusting apparatus on each hydraulic support; Its accurate positioning subsystem as stated, the equal control linkage of atomizing de-dusting apparatus on back level main frame and each the category-A node hydraulic support.
Among the embodiment of the utility model hydraulic support atomizing de-dusting control system the distance setting of each wireless module and principle as stated, identical with pinpoint coal mining system.
The course of work of the utility model hydraulic support atomizing de-dusting control system is following: when the B node advances (straight line L) with coalcutter when; Packet is sent in the broadcasting that does not stop; After receiving packet, give back level main frame and carry out data processing information from its nearer a part of category-A node; Any judge from piece category-A node nearest according to these category-A node signal intensity levels by back level main frame; Thereby judge the advanced positions of coalcutter, the atomizing de-dusting apparatus that this category-A node that while back level host computer control is confirmed and both sides are adjacent near hydraulic support is sprayed.
Because the design's principle is based on the signal strength values that extracts wireless data transceiving and relatively realizes the location; And wireless receiving signal strength values itself can be with the variation of fluctuating of factors such as environment; Therefore will restrict the precision of wireless location; A large amount of experimental results have also confirmed this problem, and promptly its signal strength difference is not obvious or unstable when 3,4 nearest nodal distances differ very little (1-2 rice).Therefore present embodiment is provided with a screening can outward with wireless module, and as shown in Figure 3, wireless module body 1 is installed in the mechanical masking shell, through the antenna receiving signal of establishing on the wireless module.Screening can comprises the metal sidewall 2 that is circumferentially set, and an end of screening can is provided with nonmetal cover plate 3, and the other end of screening can is a leading-out terminal; Wireless module is provided with one and is used to the antenna 4 that receives, transmit, and the transmitting terminal of antenna is towards nonmetal cover plate direction.In the present embodiment each fixedly the nonmetal cover plate of Zigbee wireless module is towards the coalcutter direction, the nonmetal cover plate that moves the Zigbee wireless module is over against each fixing Zigbee wireless module.
The antenna 4 of present embodiment is formed " L " shape structure by two connecting rods 41 and 42; One of them connecting rod is a main running signal bar 41; It is perpendicular to wireless module body 1; Another connecting rod 42 is the signal lever tip, signal lever tip and direction dorsad nonmetal cover plate one side parallel with the wireless module body, and the main running signal bar sees through nonmetal cover plate 3 emissions in the place ahead.
In addition, the screening can leading-out terminal is provided with a metal base plate 6, and base plate 6 is provided with wire hole 7, and the outer face of base plate is provided with a tubulose output cylinder 5 in the wire hole place.
This screening can satisfy the coal mine explosion-proof requirement on the one hand; Another very important aspect is exactly to shield the scattering degree of wireless transmitter module towards both sides; When guaranteeing that wireless transmitter module advances on the hydraulic support certain receiver module dead ahead with coalcutter; This receiver module signal strength values is the strongest, and the signal strength values of its both sides receiver module and its difference are bigger, like this could be in the abominable interference ratio of Minepit environment than under the serious situation equipment being realized accurate, stable, reliable localization.
