[0039] The brake cylinder bellows detection unit 6 is also similar in structure to the brake chain detection unit 4. Figure 6 As shown, the brake cylinder bellows detection unit 6 also includes a third box 61 and a third image acquisition device 62. The difference is that the brake cylinder bellows detection unit 6 includes two third image acquisition devices 62, which are respectively installed on both sides of the third box 61, that is, one third image acquisition device 62 is provided for each of the two side tracks 2.

[0045] The train receiving unit may also include a plurality of sensors arranged along the track 2 to obtain the train entry and exit information on the hump track 2. For example, when the train sequentially triggers a plurality of sensors in the incoming direction, it is determined that the train has entered the hump. When the train sequentially passes a plurality of sensors in the outgoing direction and there is no new trigger signal from these sensors within a certain period of time, it is determined that the train has exited the hump.
[0046] At the same time, the brake chain detection unit 4, the brake shoe detection unit 5 and the brake cylinder bellows detection unit 6 are all communicatively connected with the car receiving unit, and the image information acquired by the brake chain detection unit 4, the brake shoe detection unit 5 and the brake cylinder bellows detection unit 6 are all transmitted to the car receiving unit, and the car receiving unit transmits the above train information, entry information, exit information, and image information to the duty room for the duty room staff to comprehensively judge the relevant conditions of the train braking device so as to issue corresponding instructions.
[0047] In addition, the receiving unit also has a coordinated control function. When the information that the train enters the hump is obtained, a signal will be sent to the brake chain detection unit 4, the brake shoe detection unit 5 and the brake cylinder bellows detection unit 6 to start acquiring image information and start acquiring train information at the same time. When the receiving unit obtains the information that the train leaves the hump, a signal will be sent to the brake chain detection unit 4, the brake shoe detection unit 5 and the brake cylinder bellows detection unit 6 to stop acquiring image information, and the acquired train information, image information, etc. will be transmitted to the duty room for analysis by the duty personnel.
[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0049] The above preferred embodiments shall not be regarded as limiting the present invention, and the protection scope of the present invention shall be subject to the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications shall also be regarded as the protection scope of the present invention.
