Embodiment Construction
[0044] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0045] The present invention is an automatic monitoring system applied to the state of the brake cylinder in the railway train inspection and wind test operation, such as figure 1 As shown, it includes a camera trolley, a car number recognition unit, a power supply communication device, a vertical rail, a railside control unit and a central host.
[0046] Wherein, described vertical rail 4 is as figure 2 with image 3 As shown, it is laid on the train inspection track of the train inspection station by rail fixtures, located inside the two rails 1, parallel to the rails 1, and close to the rail 1 on one side. The cross-section of the vertical rail 4 is an "S"-shaped bent plate. The length of the cross-section of the upper bent part is x, and the value of x is small. The sliding guide frame 5 is fixed in the middle of the vertical rail 4, and the sl...

The invention discloses an automatic monitoring system and method for a brake cylinder state in wind testing work under railway train examination. The system comprises a camera trolley, a train carriage number identification unit, a power supply communication device, vertical rails, rail side control units and a center host. The method comprises the following steps of: identifying train carriage numbers by the train carriage number identification unit, acquiring image information of the bottom of a train by the camera trolley, and transmitting the image information to the center host; determining movement parameters of the camera trolley according to the train carriage number, and moving the camera trolley below a brake cylinder to be monitored under the control of the center host; and controlling a fan gate to pressurize a train braking system by the center host so as to carry out the wind testing work, and controlling the camera trolley to shoot a piston rod of the brake cylinder. The system disclosed by the invention can directly carry out the operations of image identifying and positioning according to the train carriage numbers, can be subjected to remote operation, and is accurate in positioning; the monitoring system can perform fixed-point tracking and shooting on components to be detected at the bottom of the train, and is higher in positioning precision; and the monitoring system can also carry out the dynamic shooting in moving, thus achieving an effect of dynamic failure identification through the image.
Description
technical field [0001] The invention relates to an automatic monitoring system and method for the state of a brake cylinder applied to railway train inspection and wind testing, and belongs to the technical field of train detection. Background technique [0002] In the prior art, in the railway train inspection and wind test operation, the detection of the state of the brake cylinder of the train or the detection of the mechanical parts at the bottom of the train needs to be done manually by the staff. Under harsh conditions, it cannot be performed, resulting in the positioning and detection of mechanical parts. high cost. [0003] One of the keys to realize the automation of train inspection and wind test process is the problem of brake cylinder positioning. In the process of developing the automatic monitoring system for train wind test brake cylinder piston rod status, a track and camera for taking images of the undercarriage were developed. Key systems such as trolleys....
