Coal mine down-hole positioning device and positioning method thereof

Abstract

The invention discloses a coal mine underground locating device and the locating method, which aims to overcome the technical problems of the low-sensitivity and low-precision locating by the locating device and locating method in prior art. The invention provides a locating device and the locating method with high sensitivity and high locating precision, which is safer and more reliable; the locating device in the invention is provided with a shell, on which equipped with a circuit board. The circuit board is mounted with a power source and the switch circuit. The power source and the switch circuit are connected with the interface I/O of the main chip which is connected with a signal amplifier circuit and a warning circuit; the signal amplifier circuit is connected with the technical scheme of antenna; separately calculates the distance between the signal intensity and the two communication base stations according to the signal intensity by testing the signal intensity from at least two communication base stations, and then calculates the locating method which accords with the coordinate point to the distance of the two base stations. The locating device and the locating method provided in the invention has high locating precision and high sensitivity, which is applicable to the safe production of the coal mine underground.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning instrument and a positioning method for positioning the position in a coal mine underground. Background technique [0002] At present, coal mine safety production has become one of the focuses of safety production. In coal mines with extremely complicated working conditions, it is often necessary to locate specific people or objects. At present, positioning algorithms based on existing technologies, such as RFID methods, in fact It cannot be regarded as a positioning algorithm in the strict sense. It can only judge whether the located terminal is "in" or "not in" around the detection device (reader), that is, there are only two states, "0" or "1", and one detection The radiation range of the device is a space with a radius of 50 meters. It can only judge whether the detected terminal is in this space, and the positioning accuracy is relatively poor. If the radiation range is...

[0002] At present, coal mine safety production has become one of the focuses of safety production. In coal mines with extremely complicated working conditions, it is often necessary to locate specific people or objects. At present, positioning algorithms based on existing technologies, such as RFID methods, in fact It cannot be regarded as a positioning algorithm in the strict sense. It can only judge whether the located terminal is "in" or "not in" around the detection device (reader), that is, there are only two states, "0" or "1", and one detection The radiation range of the device is a space with a radius of 50 meters. It can only judge whether the detected terminal is in this space, and the positioning accuracy is relatively poor.

If the radiation range is reduced, although the positioning accuracy can be improved, a new problem arises, that is, under the same number of detection devices (readers), the overall coverage of the detection area decreases, and most areas may not be detected at all. There is no signal coverage, so the presence of the detected terminal cannot be detected at all; this is a dilemma

In the existing technology, the technology or equipment to realize underground positioning in coal mines has technical defects such as outdated positioning methods, low sensitivity, low positioning accuracy, and poor safety. Timely and accurate positioning of objects or objects; the above-mentioned technical defects in the prior art have become a major technical problem to be solved urgently by those skilled in the art
