Problems solved by technology

[0003] However, the existing UWB does not support the communication frame filtering function on the hardware. When the system contains more ranging tag nodes to initiate ranging, it is easy to cause data flow collision interference in communication, causing ranging communication abnormalities or ranging The result is incorrect, causing the positioning to fail

Abstract

The invention discloses a UWB ultra-wideband wireless communication method and system for ranging and positioning an underground locomotive in a mine. In a ranging area, a query data packet is sent to a communication base station, and the ranging parameters issued by the communication base station are obtained. Ranging parameters include ranging permission channel, ranging time slot, ranging waiting time delay and ranging base station ID; use the ranging permission channel to send ranging data packets to ranging base station in ranging time slot, and get UWB tag The ranging distance from the ranging base station; after the ranging distance is uploaded to the ground server for position calculation, the offset of the UWB tag from the track is obtained, and the current locomotive position is obtained; the locomotive positioning in the mine The method avoids the conflict in the process of UWB tag ranging, making the positioning calculation more real-time and more accurate.

Description

technical field [0001] The invention relates to the field of distance measurement and positioning of mine locomotives, in particular to a method and system for distance measurement and positioning of underground locomotives using UWB ultra-wideband wireless communication. Background technique [0002] The underground mine has a special geographical environment, the roadway is long and narrow, and radio signal transmission attenuation is serious. GPS satellite positioning signals cannot reach underground coal mines. However, positioning technologies such as RFID, ultrasonic, and Bluetooth have short communication distances and limited positioning accuracy. At the sub-meter level, the error is relatively large, and it is difficult to meet the needs of coal mine accident rescue, transportation, and electromechanical accident prevention and control. UWB technology is a wireless communication technology based on nanosecond-level ultra-narrow pulses. This technology has the charac...
