Compressed sensing vector tracking and positioning method of engineering transport vehicle under Beidou/GPS positioning

Abstract

The invention conducts a research on a compressed sensing vector tracking and positioning method of an engineering transport vehicle under Beidou / GPS positioning. In order to strengthen the supervision strength of a coal company on a transport vehicle and avoid coal stealing and coal unloading, a Beidou / GPS satellite positioning system needs to be used for carrying out real-time positioning monitoring on the vehicle. In order to obtain the accurate position of the vehicle, a time-of-arrival (TOA) ranging principle is used in the invention. Firstly, the transmitting time of signals transmittedfrom a satellite to a receiver needs to be defined, and the transmitting speed of electromagnetic waves is multiplied by the transmitting time to obtain the distance from the satellite to a user vehicle. The system comprises a space part, a ground part and a Beidou / GPS compatible user terminal. When a vehicle terminal receiver processes signals, the vector tracking algorithm based on compressed sensing is utilized, due to the fact that the calculated amount in the tracking process is great, a large amount of redundant information is generated, and the calculated amount and hardware complexitycan be greatly reduced through the vector tracking algorithm based on compressed sensing.

Description

technical field [0001] The invention relates to a monitoring and positioning method for engineering transport vehicles, in particular to a Beidou / GPS positioning and compressed sensing vector tracking method. Background technique [0002] As we all know, my country is a big coal country, and the coal industry is a basic industry in my country. Coal transport vehicles are also inevitably increasing gradually. Coal companies cannot always achieve satisfactory results in the management of coal transport vehicles, and too many engineering vehicles will cause a lot of traffic jams. Due to the negligent management of the coal transportation vehicles of the project, accidents such as staff stealing coal and unloading coal halfway will occur during the transportation of the vehicles. In order to strengthen the coal company's supervision of transportation vehicles and avoid the occurrence of coal stealing and coal unloading, the real-time positioning and monitoring system of vehicle...
