Problems solved by technology

The disadvantage of the cross-section detection method is that the running speed of the detection vehicle is required to be very low during the detection process, and it is impossible to detect the influence of the vibration offset of the train in the high-speed running state. The geometric offset is automatically and continuously increased, but the contact frame cannot be automatically and continuously increased, which greatly reduces the accuracy and precision of detection
The disadvantages of the laser radar detection method are: first, the laser radar itself has a system error of about 15mm, which cannot meet the requirements of accurate measurement; The principle of pulse echo ranging, the scanning frequency is generally around 50HZ, which is not suitable for high-speed and real-time detection requirements

Abstract

The invention provides a metro gauge detecting system and a detecting method thereof and belongs to the field of urban mass transit gauge detection. The metro gauge detecting system comprises a data processing analyzing system and an image collecting system 10, a vibration compensation system and a positioning system which are respectively connected with the data processing analyzing system. The accuracy and precision can be both increased by the measurement of the metro gauge detecting system in each section of road; the system error is reduced; the control on the system is excellent; the manpower resource and the material resource are simultaneously saved; the efficiency is increased; and the metro gauge detecting system is suitable for high-speed and real-time detection requirement.

Description

technical field [0001] The invention relates to the field of urban rail transit boundary detection, in particular to the field of urban rail transit subway boundary detection. Background technique [0002] With the progress of society, the continuous expansion of urban scale and the rapid increase of population density, the situation of urban traffic congestion is becoming more and more serious. Due to its advantages of large capacity, low energy consumption, good punctuality, fast safety, and high traffic efficiency, subway has become one of the important directions for the development of urban rail transit, and it is an effective and long-term way to solve traffic congestion in big cities. In recent years, my country's urban subway and light rail transportation has developed vigorously. Among the 48 cities with a population of more than 1 million in the country, more than 30 cities are currently carrying out preliminary work or construction of rail transit, and 55 lines a...
