Embodiment 1

[0043] A mine personnel positioning system, such as figure 2 As shown, it includes: an identification card, a UWB positioning base station 2, and a UWB beacon 3. The identification card includes an identification card 1 controller, a low-frequency wake-up module and an identification card 1 UWB communication module; the UWB positioning base station 2 includes an omnidirectional UWB antenna A, an omnidirectional UWB antenna B and a positioning master station; the UWB beacon 3 Including controller, low frequency carrier signal transmitting module, UWB communication unit and hydraulic support 4 controller communication module. In order to simplify the description, the omnidirectional UWB antenna A and the omnidirectional UWB antenna B are referred to as two omnidirectional antennas AB for short.

[0044] Among them, the identification card 1 is used to locate underground personnel, and the identification card 1 controller is used to control the working mode of the identificatio...

Embodiment 2

[0053] A mine personnel positioning system, comprising:

[0054] Identification card 1, used to locate underground personnel;

[0055] UWB positioning base station 2, used for positioning the distance and orientation of the identified card 1 relative to the UWB positioning base station 2;

[0056] The UWB beacon 3 is arranged in the middle of the hydraulic support 4, and transmits a low-frequency carrier signal; the low-frequency carrier signal carries the serial number of the hydraulic support 4 corresponding to the UWB beacon 3;

[0057] Wherein, when the identification card 1 is within the low-frequency signal range, the identification card 1 is used to receive the low-frequency carrier signal transmitted by the UWB beacon 3, and locate the number of the hydraulic support 4 where it is located; the UWB positioning The base station 2 is used to obtain the number of the hydraulic support 4 corresponding to the identification card 1, and locate the location according to the n...

Embodiment 3

[0062] A mine personnel positioning system, comprising:

[0063] Identification card for locating underground personnel;

[0064] UWB positioning base station, used to locate the distance and orientation of the identified card relative to the UWB positioning base station;

[0065] The UWB beacon is set in the middle of the hydraulic support and emits a low-frequency carrier signal; receiving the UWB data sent by the identification card and carrying the serial number information of the hydraulic support. The low-frequency carrier signal carries the serial number of the hydraulic support corresponding to the UWB beacon;

[0066] Wherein, when the identification card is within the low-frequency signal range, the identification card is used to receive the low-frequency carrier signal transmitted by the UWB beacon, and locate the number of the hydraulic support where it is located; the UWB positioning base station is used to obtain The number of the hydraulic support correspondin...

Abstract

The invention relates to the field of personnel positioning, in particular to a mine personnel positioning system and method. The system comprises an identification card; a UWB positioning base station; a UWB beacon; when the identification card is in a low-frequency signal range, the identification card is used for receiving a low-frequency carrier signal transmitted by the UWB beacon and positioning the serial number of the hydraulic support where the identification card is located; and the UWB positioning base station is used for acquiring the hydraulic support number corresponding to the identification card, and positioning the distance and orientation of the identification card relative to the UWB positioning base station according to the hydraulic support number corresponding to the identification card, the width of the hydraulic support and the number of the hydraulic support where the UWB positioning base station is located. The problem that in the prior art, mine personnel cannot be accurately positioned on the working face and the non-working face of a mine at the same time is effectively solved.

Description

technical field [0001] The invention relates to the field of personnel positioning, in particular to a mine personnel positioning system and positioning method. Background technique [0002] Personnel are the foundation of coal mining, and ensuring the safety of personnel is the goal that enterprises have been pursuing. Personnel positioning plays a very important role in coal mine production. The coal mine personnel positioning system can accurately reflect the real-time distribution of personnel and equipment in various underground areas, so that managers can grasp the location and movement trajectory of personnel and equipment at any time, and carry out more reasonable dispatch management. Especially when there are potential safety hazards or emergencies, they can respond as soon as possible to reduce mine losses. [0003] UWB positioning technology is recognized by the indoor positioning industry as the positioning technology with the highest positioning accuracy. With...
