Background
A switch is a line connection device for switching a train from one track to another track, and is a large family, most commonly a common single switch. A switch is generally composed of three units, a switch unit including a stock rail, a point rail and a switch machine, a connecting portion, a frog and a guard rail. When a train changes from the track A to the track B, the switch machine is operated to move the switch point, the switch point 1 is closely attached to the stock rail 1, the switch point 2 is separated from the stock rail 2, the track B is opened, the track A is closed, and the train enters the connecting part and transits to the frog and the guard rail unit along the guide curve rail. The turnout has the characteristics of large quantity, complex structure, short service life, limitation of train speed, low traffic safety, large maintenance and repair investment and the like, and is called three weak links of a track together with a curve and a joint.
In the use process, the turnout is subjected to the expansion and contraction of heat and cold of a steel rail caused by the operation impact of a train and the temperature change, the geometric dimension of the turnout is changed, the point switch machine cannot drive the point rail to be converted to a specified position, the faults of point squeezing, meter losing, card grinding and the like of the turnout are caused, and the train line is further interrupted. The geometric size of the turnout changes mainly into the following two types:
1. transverse moving and shifting of turnout steel rails: after the turnout steel rail moves transversely or moves, the turnout is closely attached, the opening and the track gauge are changed, and faults such as turnout squeezing, turnout drop, notch clamping and the like can be caused;
2. point rail play (creep): point rail play refers to longitudinal play of the point rail along the line direction. The standard of the combined treatment of the power and the electricity is not more than 20mm, the longitudinal movement amount of the switch rail exceeds the standard, and the harm is that the action rod and the indication rod of the switch are stiff, the flexible action of extending and pulling the action rod and the indication rod into a point switch is influenced, and then the switch fault of the switch is caused.
At present, in the daily maintenance of the turnout, due to the fact that a plurality of objects are patrolled and the configuration of human resources is insufficient, the defects of hidden dangers cannot be effectively checked in time, and then the turnout cannot be checked in time after a fault occurs, and the train line is interrupted.

Can obtain rail stock rail sideslip displacement, stock rail flexible displacement, switch blade sideslip displacement, the flexible displacement of switch blade through displacement image data and environmental data analysis, and then calculate switch structure geometric dimensions values such as switch closure, opening, gauge, flexible, creep, through comparing these displacement dimensions, geometric dimensions and standard value, alright in order to reach the switch inspection position and whether have the displacement defect.
And finally, the transmission module in the turnout comprehensive monitoring control box outputs the final monitoring result to the monitoring terminal in a wireless and/or wired mode.
When the defects occur, the monitoring host can control the track system to implement corresponding emergency measures and alarm to inform workers to confirm and maintain the defects. Therefore, the monitoring manpower is saved, the monitoring accuracy and timeliness are improved, and the rail transportation safety is ensured.
It should be noted that, the method for determining whether the turnout inspection portion has a defect according to the initial data is a function designed by software, and a person skilled in the art should design corresponding image processing software based on the function realized by the person skilled in the art, and the design of each parameter in the software should be grasped by the person skilled in the art, which is not described herein again.
In summary, the turnout operating condition comprehensive inspector, the turnout operating condition comprehensive monitoring system and the turnout operating condition comprehensive monitoring method provided by the embodiment comprise a structure monitoring module, an appearance monitoring module, an environment monitoring module and a main control module; the structure monitoring module is used for acquiring displacement image data of stock rails and switch rails at turnout inspection positions; the appearance monitoring module is used for acquiring appearance image data of stock rails and switch rails at turnout inspection positions; the environment monitoring module is used for acquiring environment data of a turnout inspection part; the main control module is used for controlling the structure monitoring module, the appearance monitoring module and the environment monitoring module so as to obtain the displacement image data, the appearance image data and the environment data, and the main control module is used for acquiring the environment brightness of the turnout inspection part and the temperature and humidity inside the turnout working condition comprehensive inspection device in real time, and summarizing the obtained displacement image data, the appearance image data, the environment brightness and the temperature and humidity inside the turnout working condition comprehensive inspection device into initial data. Through the setting of each functional module in the switch operating mode comprehensive inspection ware, initial data that can real time monitoring switch inspection position to can acquire the state at switch inspection position in real time. Therefore, the state of the turnout inspection part can be accurately inspected without excessive inspection manpower. The problem of how to carry out timely effective inspection to the switch is solved.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
