Abstract
The invention discloses a rail transit fault on-line monitoring system based on the Internet of Things technology. The rail transit fault on-line monitoring system detects the physical changes of a tunnel, a bridge, a rail and the environment, achieves fault monitoring and early warning, and coordinates running of each train through a dispatching platform based on the Internet of Things to achieve the purpose of safe running. According to the rail transit fault on-line monitoring system, a wireless sensor is used for forming a wireless sensor network, the large wireless sensor network is formed on the trains and outside the trains, workers on the ground and workers on the trains can grasp the situations of one another immediately to achieve monitoring implementation, information synchronization and advanced warning. By means of Big Dipper positioning, vibrating spectrum analyzing, axle temperature monitoring, axial stress monitoring, crack monitoring, motor state monitoring, tunnel vibration monitoring, tunnel wind power monitoring, rail flatness monitoring, bridge health monitoring and the like, the factors affecting safe running of the trains are monitored and comprehensively analyzed, and an expert system gives guiding ideas and issues quick response plans in case of emergency.
Description
Technical field
The present invention relates to a kind of track traffic On-line Fault monitoring system based on technology of Internet of things, be specifically related to all kinds of external factors of a kind of real time on-line monitoring rail transit train axle temperature, stress, cracks, motor running condition, train operation as wind-force, vibration, bridge health monitoring in tunnel.
Background technology
Because economic society high speed development and size of urban population sharply expand, urban track traffic presents high speed development, the constantly setting a records such as track length, station quantity, newly-increased platform, the passengers quantity transporting is also more and more, and to track safety traffic, work is had higher requirement.The track traffic service mode in past has no longer met the demand of modern railway transportation development, along with more and more outstanding safety problem, field of track traffic must be alleviated the development model under new background by self introducing up-to-date technology and new departure, utilize Internet of Things " sense, pass, know, with " the each large traffic operation business cooperation of technology promotion, efficient operation, effectively alleviate large passenger flow, the pressure that the emergency case such as keep a lookout of public security causes track traffic, improve metro safety operation and the level of information service is provided towards the public, for the safe cause of new period track traffic is explored a practicable road.
Summary of the invention
Goal of the invention: the object of the invention is the comprehensive all kinds of parameters of track traffic On-line Fault monitoring system based on technology of Internet of things, by comprehensive analysis processing and analysis expert suggestion, provides powerful guarantee to train safe situation.
Technical scheme: the present invention has taked following technical scheme:
Utilize the dipper system of China's independent development to locate in real time train, the speed to train driving, position, spaces of vehicles are monitored the generation that prevents vehicle collision accurately.
By a series of means such as the vibration analysis to axletree, bearing temperature monitoring, stress monitoring, crack monitorings, axletree is carried out to many-side monitoring, prevent in time axle fracture, cut the generation of the situations such as axle.
To prevent that the burst out-of-control condition running in train driving process from occurring, and finds motor fault in time to motor status monitoring.
The situations such as tunnel vibration, wind-force are monitored, prevent that unforeseen circumstances from appearring in train while travelling in tunnel.
Can prevent from causing because bridge is in bad repair the train travelling to have an accident by actv. to bridge health monitoring.
Total data is carried out to data transmission by wireless sensor network, GPRS/CDMA network, finally send data to ground maneuvers center and unify to gather, analyze, process, and result is shown in many ways.
