CN2711751Y - Positioning saving device for downhole person - Google Patents

Abstract

The utility model relates to a positioning saving device for downhole person comprising a base station, a portable mobile device and a computer in the ground center. The base station is connected with the computer in the ground center by communication cable. The portable mobile device carried by the downhole person sends out a timing radio frequency signal with the character of the representation which is received by the base station and is resent to the ground control centre in normal operation. A coded signal which is from the downhole base station is received by the control center. The activity orientation and the coordinates in real-time of the down-hole movable target can be known by analyzing and processing the coded signal. In the emergency, the ground control centre can send out timely alarm signals of sound, light and shake etc. to the person in the hazardous areas through the base station in order to escape in time. The person in trouble can send out a distress signal for surviving to the ground control centre via the portable mobile device when an accident happens. The system can lock each approximately communicating position of the person in trouble and in distress in time, and the accuracy is controlled within 15 meters, which brings the quickest and the most exact information for the saving and preventing working.

Description

A kind of personnel in the pit locatees search and rescue device

Technical field

The utility model relates to supervisory system, a kind of personnel in the pit's fixed-position searching device of saying so more specifically.

Background technology

Domestic various collieries do not have homogeneous system basically at present, only have the large-scale colliery of fraction to adopt non-contact IC card work attendance mode to position, and coverage is no more than 1 meter, far from the location.

Two kinds of personnel in the pit's locator meamss are abroad generally arranged, a kind of is to adopt satellite-based GPS positioning system, and shortcoming is that cost is too high, does not meet Chinese people intensive mining mode fully, be subjected to the influence of environmental interference very big simultaneously, also do not meet the mine truth that China is widely distributed, situation is totally different.

The second way is to adopt the search and rescue mode of surveying the heartbeat pulse, relatively is fit to earthquake relief work, the closely search and rescue activity of phenotype (coverage is no more than 50 meters on the face of land), and also can't search the wrecked personnel that stop heartbeat.

Summary of the invention

The purpose of this utility model is to be mainly used in moving target under the various mines (personnel and vehicle) to carry out wireless location and tracking, (exceed standard such as gas density etc.) can in time notify the hazardous location evacuating personnel before accidents such as mine disaster take place, after taking place, accident can in time lock stranded and wrecked personnel's position (precision is in 15 meters), for search-and-rescue work brings the fastest information the most accurately.

The technical solution of the utility model is as follows:

A kind of personnel in the pit locatees the computing machine that search and rescue device comprises base station, portable mobile device, center, ground, by telecommunication cable the computing machine of base station with the center, ground is linked to each other.

Described base station comprises wireless frequency modulation half-duplex operation module (STR-8), micro controller module, button, hummer, pilot lamp, interface, AC power and accumulator.

Described portable mobile device comprises wireless frequency modulation half-duplex operation module (STR-8), micro controller module, button, hummer, pilot lamp, interface, dry cell.

Described micro controller module comprises microcontroller chip ICU1 (89C2051) and register ICU3 (74AIS166).

During normal operating conditions, the portable mobile device that the personnel in the pit carries regularly sends the radiofrequency signal with representative capacity feature, receives through the base station, down-hole, re-sends to the ground control centre.Control center receives from the coded signal on the base station, down-hole, carries out analyzing and processing, learns the real-time activity orientation and the coordinate of down-hole moving target.

When the fire damp concentration detector detected accident omens such as gas density exceeds standard, the ground control centre can in time be sent alerting signals such as sound, light, vibrations by the base station, down-hole to being in the hazardous location personnel, reaches the purpose of timely evacuation.

After accidents such as mine disaster take place, if the data transmission channel of system still keeps, can in time lock stranded and wrecked personnel's position (precision is in 15 meters), for search-and-rescue work brings the fastest information the most accurately, indicator of trapped personnel can (this device be placed in the miner's safety helmet by portable mobile device simultaneously, impaired probability is relatively low), control center sends the distress signal of surviving earthward, if these personnel do not send signal for a long time, show that then its injured having reached loses mobility or wrecked.

After accidents such as mine disaster took place, if the interrupted words of the data transmission channel of system, system can in time lock the approximate location that stranded and wrecked personnel communicate by letter for the last time, and precision is in 15 meters, for search-and-rescue work brings the fastest information the most accurately.

Beneficial effect:

1. moving target is monitored query function in real time:

● can inquire about the quantity and the distribution situation (size of distributed areas is by the quantity decision of downhole data reception, repeating base station) of current personnel in the pit, locomotive in real time;

● arbitrary appointment personnel in the pit, locomotive are in current or residing zone of the appointment moment;

● arbitrary movable trace of specifying personnel in the pit, this day of locomotive or appointed day;

● can carry out real-time follow-up to specific personnel, locomotive and show.

2. safety guarantee function:

● gate inhibition's function:

Some important chambers of down-hole, dangerous situation (as blind lane etc.), then can effectively stop violating the regulations entering as the voice informing module, and the personnel record that will break rules and regulations is on record;

● lose warning:

Check personnel on duty at each class end, loses then as the discovery personnel and report to the police, so that the operator on duty verifies; Perhaps find to surpass the given time, automatically alarm and form related personnel's information such as list in the ground control centre in the down-hole time;

● rescue is searched:

Can search and locate scene of the accident buried person person, so that rescue in time.

3. current mode is unrestricted, to tested personnel without limits through the current mode of base station, down-hole, allow many people with " entering in single file ", " " mode does not influence personnel in the pit's normal current and normal operation by the base station, down-hole in groups in groups;

4. simple in structure, flexible configuration can be provided with the down-hole flexibly according to concrete needs and investment situation and send out the base station.It is many more that the base station, down-hole is provided with, and then the locating area of Hua Fening is many more, and the spatial dimension of personnel positioning is accurate more;

5. safely, reliably, long-time 24 hours uninterrupted operate as normal of energy under rugged surroundings, the design stream time of portable mobile device surpasses half a year.
