High-speed rail positioning device and positioning method

Abstract

The invention discloses a high-speed rail positioning device, which includes a power supply module, a GNSS positioning module, a control module, a data interface circuit, a radar speed measurement module and an acceleration detection module; the power supply module supplies power; the GNSS positioning module positions and uploads a control module; and the radar speed measurement module detects The speed is uploaded to the control module; the acceleration detection module detects the acceleration and uploaded to the control module; the control module positions the high-speed rail and communicates with the outside through the data interface circuit. The invention also discloses the positioning method of the high-speed rail positioning device, which includes correcting the detection value of the acceleration sensor to the acceleration value of the high-speed rail vehicle; determining whether positioning of a new line is required; calculating the angle between the high-speed rail vehicle and the horizontal plane; and calculating the superelevation value of the outer rail And determine the driving position of the high-speed rail vehicle; locate the high-speed rail vehicle. The invention realizes the real-time positioning and real-time acquisition of the position of the high-speed rail vehicle, and the invention has the advantages of accurate positioning, convenient maintenance and low cost.

Description

technical field [0001] The invention specifically relates to a high-speed rail positioning device and a positioning method. Background technique [0002] With the development of the country's economy and technology and the improvement of people's living standards, high-speed rail has gradually become the preferred mode of transportation for people's daily travel due to its advantages of fast operation, good comfort, and high cost performance. Because of this, the monitoring of various states of the high-speed rail during its operation has become a top priority. [0003] When the high-speed rail vehicle is running, it needs to locate its own position at any time, so that it can effectively control itself. At present, the most commonly used high-speed rail positioning technology is GPS positioning technology, and GPS positioning technology is by far the most mature positioning technology in the world. However, because the high-speed rail often needs to pass through the tunne...

Problems solved by technology

However, the inertial navigation system has the problem of high cost, and it has accumulated errors, so its positioning accuracy is relatively low during high-speed rail positioning, and the maintenance of the inertial navigation system is also very troublesome
