The recording component 10 uploads the recorded relevant data information to the control end, and the control end completes the detection based on the relevant data information.

[0051] Embodiment 2:

[0052] On the basis of any of the above embodiments, the fixing device comprises an adsorption member 21, an extension member 231 and an adsorption mounting member, wherein the adsorption mounting member is used to fix the adsorption member 21 to the extension member 231; and the adsorption member 21 is used to be adsorbed and fixed to a target position of a vehicle body; the extension member 231 is connected between the recording component 10 and the adsorption member 21, and the extension member 231 is used to adjust the relative position and / or relative distance of the recording component 10 relative to the adsorption member 21;

[0053] The recording tool provided in the present application is suitable for audio and / or video detection of equipment on the top of an EMU. When in use, the recording tool is fixed to the vehicle body by a suction cup, and the relative position and / or relative distance of the recording component 10 with respect to the adsorption component 21 is adjusted by the extension piece 231, such as: the position and distance of the recording component 10 with respect to the adsorption component 21 are adjusted by the extension piece 231, thereby achieving the adjustment of the angle and distance of the recording component 10, which not only enables the recording component 10 to obtain the target audio and / or target video, but also the working range of the recording component 10 can be expanded by the extension piece 231. In addition, the adsorption fixing method of the fixing device can also improve the convenience of fixing the recording component 10 on the vehicle body, reduce the labor intensity of on-site staff, avoid shaking caused by workers holding the tool, and improve the recording quality.

[0054] In addition, in order to ensure the adsorption and fixing strength of the adsorption member 21, the following settings are made on the basis of the above-mentioned embodiment 2: the number of the adsorption members 21 is set to at least three, and at least three of the adsorption members 21 form a triangle arrangement. By arranging at least three adsorption members 21 in a triangle, the adsorption and fixing strength between the recording tooling and the vehicle body can be improved by utilizing the stability of the triangle. Figure 1-6 As shown, three adsorption members 21 are provided, and the three adsorption members 21 are arranged in a triangle. Of course, if the number of adsorption members 21 is set to four, the four adsorption members 21 are arranged in a diamond shape, so that three adjacent adsorption members 21 can form a triangle arrangement.

[0055] Therefore, the number of the adsorption members 21 is set to at least three, and at least three of the adsorption members 21 form a triangular arrangement. Under this premise, the following settings can be made for the above-mentioned adsorption mounting member: the adsorption mounting member includes: a first mounting rod 222, a second mounting rod 223, a mounting hole and a mounting pin 224, wherein the number of the mounting holes is set to multiple, and the multiple mounting holes are all opened at the end of the extension member 231; the first mounting rod 222, the number is set to multiple, passes through the corresponding mounting holes, and the two ends are respectively fixed with the corresponding adsorption members 21; the second mounting rod 223, one end passes through the corresponding mounting hole, and the other end is fixed with the corresponding adsorption member 21; the mounting pin 224, the number is set to multiple, and is respectively arranged between the first mounting rod 222 and the mounting hole, and between the second mounting rod 223 and the mounting hole, for limiting and fixing the first mounting rod 222 and the second mounting rod 223; wherein the adsorption members 21 located on the first mounting rod 222 and the second mounting rod 223 are located on the same horizontal plane and form at least one triangular structure.

Under this premise, corresponding limiting structures (such as limiting holes matching the mounting pins 224) are provided on the first mounting rod 222, the second mounting rod 223 and the extension member 231.

[0057] In addition, the first mounting rod 222 and the second mounting rod 223 can be configured to form a threaded connection and / or a ball hinge structure with the corresponding adsorption member 21.

In order to make the unlocking work between the first tube 2311 and the second tube 2312 more labor-saving and convenient, the pin hole 2322 is configured as an arc structure, and further configured as a trumpet-shaped configuration, and accordingly, the contact surface of the spring pin 2324 that contacts the pin hole 2322 is also configured as an arc configuration; further, the spring pin 2324 is configured as a ball structure.

[0091] Two mounting holes are provided at the end of the first tube 2311 away from the second tube 2312, and the two mounting holes are distributed in sequence along the length direction of the first tube 2311, wherein one end of the second mounting rod 223 is arranged in one of the mounting holes, and the other end extends outward from the one mounting hole and is fixed with an adsorption component 21; the first mounting rod 222 passes through the other mounting hole, and both ends can be adaptively bent and each is fixed with an adsorption component 21. It is worth noting that in order to further simplify the structure, the two mounting holes are arranged to be axially vertical; wherein the first mounting rod 222 and the second mounting rod 223 can be rotatably set in their respective mounting holes, so as to adjust the two adsorption components 21 on the first mounting rod 222 and the adsorption component 21 on the second mounting rod 223 to be located in the same horizontal plane. Based on this, the three adsorption parts 21 can be adsorbed and fixed to the target position of the vehicle body in a triangular structure; of course, if the target position of the vehicle body is not set in a plane, the three adsorption parts 21 can also be adjusted to form a triangular structure to match the target position of the vehicle body by the first mounting rod 222 and the second mounting rod 223 being both rotated in their respective mounting holes; thereafter, when the first mounting rod 222 and the second mounting rod 223 are both rotated to the appropriate position in their respective mounting holes, the first mounting rod 222 and the second mounting rod 223 are respectively limited and fixed to the corresponding mounting holes by inserting their respective mounting pins 224. Under this premise, corresponding limiting structures (such as: limiting holes matching the mounting pins 224) are provided on the first mounting rod 222, the second mounting rod 223 and the first tube 2311.

[0092] exist Figure 5 In the embodiment, the pin hole 2322 is a blind hole. Figure 6 In the figure, the pin hole 2322 is a through hole, and the structure of the pin hole 2322 can be set as needed.

[0093] In addition, the first mounting rod 222 and the second mounting rod 223 can be configured to form a threaded connection and / or a ball hinge structure with the corresponding adsorption member 21. The threaded structure can realize the rapid replacement of the adsorption member 21, and the ball hinge structure can also make multiple adsorption members 21 better adapt to the shape of the target position of the vehicle body.

[0094] The recording tool provided in the present application is suitable for audio and / or video detection of equipment on the top of an EMU. When in use, the recording tool is fixed to the vehicle body by a suction cup, and the relative position and / or relative distance of the recording component 10 with respect to the adsorption component 21 is adjusted by the extension piece 231, such as: the position and distance of the recording component 10 with respect to the adsorption component 21 are adjusted by the extension piece 231, thereby achieving the adjustment of the angle and distance of the recording component 10, which not only enables the recording component 10 to obtain the target audio and / or target video, but also, the working range of the recording component 10 can be expanded by the extension piece 231, and the adsorption fixing method of the fixing device can also improve the convenience of fixing the recording component 10 on the vehicle body, reduce the labor intensity of on-site workers, avoid shaking caused by workers holding the tool, and improve the recording quality.
