Abstract
The utility model discloses a coal mine underground worker positioning device based on RFID. The coal mine underground worker positioning device comprises an upper computer arranged in a ground monitoring center. The upper computer is connected with and is in communication with underground positioning base stations through an RS485 serial bus, and the underground positioning base stations form a communication network through the RS485 serial bus and are in communication with an underground wireless data terminal in a wireless connection mode. When underground workers enter a base station signal covering range of a certain area, radio-frequency signal reader-writers in the base stations read wireless data terminal information carried by the workers, after read by the positioning base stations, data are processed through a microprocessor and transmitted to the upper computer through the RS485 serial bus, the movement tracks and the distribution condition of the underground workers can be obtained by the upper computer through analysis according to the information, the underground workers can be positioned in real time, the distribution condition of the underground workers is rapidly mastered when an accident happens so that most effective rescuing measures can be taken, and the coal mine underground worker positioning device has the advantages of being simple in structure and complete in function.
Description
Technical field
The utility model relates to REID field, particularly a kind of colliery based on RFID personnel positioning apparatus of going into the well.
Background technology
China is consumption of coal big country, the national pillar industry of Coal Industrial Ye Shi China.According to statistics, in China's industrial production, the most serious industry of casualty accident is exactly coal industry.Coal mining is mainly taking down-hole as main, so that personnel in the pit's safety problem just seems is particularly important.In recent years, the wide and operation roadway in mining scope distributed areas is constantly deepened, and mine production process is many, mine work under bad environment, type complexity, mobility of people is large.Be limited to the present situation of domestic coal mining, aboveground personnel go back imperfection to the monitoring of down-hole, grasp clearly not to subsurface environment, personnel's distribution situation.Accident cannot be learnt personnel in the pit's particular location after occurring, and is difficult to launch the most effectively rescue.The existing navigation system at present indivedual collieries is to rely on wired system signal transmission, but after accident generation, the power system of down-hole is often cut off, and relies on the navigation system of wired system signal transmission to be just difficult to play a role again.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to propose a kind of colliery based on RFID personnel positioning apparatus of going into the well, and can realize real-time location to personnel in the pit, has feature simple in structure, perfect in shape and function.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of colliery based on RFID personnel positioning apparatus of going into the well, comprise the host computer that is arranged at ground monitoring center, the host computer news that work of going forward side by side that are connected with down-hole locating base station by RS485 universal serial bus, between the locating base station of down-hole, by RS485 universal serial bus composition communication network, down-hole locating base station is carried out communication by wireless connections mode and downhole wireless data terminal.
Described down-hole locating base station is made up of microprocessor and radiofrequency signal read write line, be arranged on underground passage intersection and underground work region, quantity is at least one, and each down-hole locating base station is provided with a fixing geocoding, corresponding with this region physical location.
Described wireless data terminal is carried by the workman that goes into the well, and quantity is at least one, and each wireless data terminal is provided with a fixing geocoding, corresponding with the workman's that goes into the well identity information.
Because the utility model adopts radio RF recognition technology, i.e. RFID technology, can be identified target and be read and write data by radio signals, and without set up mechanically contact between data terminal and Surveillance center, application restricted gender is little; Down-hole locating base station is arranged on underground passage intersection and underground work region, can ensure to make signal to cover all positions, down-hole; By the wireless data terminal carried by the workman that goes into the well in real time earthward Surveillance center transmit my positional information, once down-hole has an accident, even if down-hole power system breaks down, also can grasp rapidly personnel in the pit's distribution situation, to launch the most effectively to succour measure.
