Description

A kind of Personnal positioner under well based on RFID

Technical field

The utility model relates to personnel in the pit's positioning field, particularly relates to a kind of Personnal positioner under well based on RFID.

Background technology

In recent years, constantly to expand and operation roadway is constantly deepened along with mining scope, aboveground personnel effectively can not monitor personnel in the pit, locate and protect, and accident cannot learn the particular location of personnel in the pit after occurring, and are difficult to launch the most effectively to succour.The current underground communica tion of China and navigation system mostly adopt the wire communication mode of cable laying, to lay and maintenance cost is very high and positioning precision is low, some large-scale mine have employed wireless location system, wireless location system based on RFID technique ensure that the accuracy of the unique of signal and information, but the existing Personnal positioner under well based on RFID technique, still there is complex structure, cost is high, the shortcomings such as data transmission is unstable, location inaccuracy.

Utility model content

In order to solve the shortcoming existed in prior art, the utility model provides a kind of Personnal positioner under well based on RFID, and its structure is simple, wiring is convenient, uses simple method to realize consummating function, and data transmission is stable, and registration, concrete technical scheme is as follows:

A kind of Personnal positioner under well based on RFID, comprise RFID that personnel in the pit carries with, underground location base station, Zigbee network and host computer, host computer to be connected with underground location base station by Zigbee network, and going forward side by side works interrogates, and the RFID that underground location base station is wirelessly carried with personnel in the pit carries out communication; Underground location base station comprises rfid interrogator, single-chip microcomputer, key switch, LED and alarm, and Zigbee network comprises Zigbee router and Zigbee telegon; RFID and rfid interrogator wirelessly transmit radiofrequency signal, single-chip microcomputer respectively with rfid interrogator, key switch, LED and alarm wired connection, single-chip microcomputer and Zigbee router wired connection, Zigbee router and the wireless connections of Zigbee telegon, Zigbee telegon and host computer wired connection.

Described single-chip microcomputer adopts the MSP430F149 of American TI Company.

Described single-chip microcomputer MSP430F149 is connected by RS232 serial ports with described rfid interrogator.

Described single-chip microcomputer MSP430F149 is connected by RS232 serial ports with described Zigbee router.

Described Zigbee telegon is connected by Ethernet interface with described host computer.

Described Zigbee router and described underground location base station, 1 Zigbee router is connected with 1 ~ 4 underground location base station.

Compared with prior art, the beneficial effects of the utility model are:

The utility model structure is simple; By the setting of key switch, LED and alarm, simple method is used to achieve perfect function; Based on the wireless location of RFID technique and the wireless telecommunications of Zigbee network, make wiring convenient, and achieve the accurate stable transmission of data and the accurate location of device.

Accompanying drawing explanation

Fig. 1 is a kind of Personnal positioner under well schematic diagram based on RFID.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with accompanying drawing 1 and embodiment, the utility model is further elaborated.

Described Zigbee router and described underground location base station, 1 Zigbee router is connected with 1 ~ 4 underground location base station, moderate with the underground location base station number of Zigbee routers exchange data, data also can be made to transmit stable, registration.

Described LED is status indicator lamp, when underground location base station normally works, LED keeps flicker, the personnel in the pit just known locating base station having LED to glimmer is normal, and when dangerous situation occurs in down-hole, personnel in the pit can push button to the locating base station nearest and working properly apart from oneself switch, send an SOS, meanwhile, when subsurface environment is dim, LED itself can make this locating base station eye-catching.

When not pushing button switch, personnel in the pit carries after RFID enters the underground location base station signal coverage in a certain region, rfid interrogator in underground location base station reads the RFID information that these personnel carry with at once, after underground location base station reads data, by Zigbee network, data are sent to host computer through single-chip microcomputer process, host computer can obtain real-time activity track and the distribution situation of personnel in the pit by analysis according to the information received.

When there is dangerous situation in down-hole, personnel in the pit pushes button switch, Single-chip Controlling alarm equipment alarm, notify that dangerous situation occurs in aboveground personnel down-hole, simultaneously, obtain information in RFID by rfid interrogator, by Zigbee network, person number's information and locating information are sent to host computer through single-chip microcomputer process, just can accurately navigate to personnel in the pit and position when aboveground personnel hear chimes of doom.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
