Description

TECHNICAL FIELD

[0001] The utility model relates to EMU equipment technical field, concretely relates to a standard EMU passenger room monitoring lens shielding cover frock. BACKGROUND

[0002] In order to monitor the safety situation in the car in real time, timely find suspicious behavior or potential security threat, maintain the order in the car, the Fuxing intelligent standard EMU passenger room car will generally be equipped with hemispherical high-definition monitoring camera on the front and rear sides of roof board, these cameras also play an important role in emergency response (such as fire alarm), lost and found, passenger flow statistics, theft prevention and loss prevention etc.But in the abnormal situation, EMU must take security measures, eliminate all the possibility of leaking confidential information.This time passenger room monitoring camera does not need to collect passenger room information again, and must prevent the information leakage in the car as the main. Since the Fuxing intelligent EMU passenger room environment adopts integrated design, the passenger room monitoring camera is not convenient to completely detach, so it is necessary to use shielding means to block its information collection function. In the original operation process, the EMU mechanic generally uses shielding (such as light shielding tape) to paste on the passenger room camera protection cover for shielding, and completes the operation after confirming that each camera is pasted firmly and has no dead angle.

[0003] But when shielding operation is carried out by using shielding, the commonly used shielding is generally light shielding tape, and when there is much dust in the operation process, the adhesion of the light shielding tape will decrease, and even if it is pasted firmly in the operation, it will also fall off during the train running; when the passenger room camera is shielded by using light shielding tape, since the camera protection cover is hemispherical, the tape will wrinkle during pasting, which not only causes dust to enter, but also transmits light, and there is a risk of information leakage; when the light shielding tape is pasted on the passenger room camera protection cover for a long time, the adhesive substance on the tape is easy to adhere to the passenger room camera protection cover, so that the protection cover becomes dirty, affecting the normal use of the camera; using the tape to shield the camera is a shielding measure without any protection means, and anyone can damage it during driving or operation, thereby finally leading to incautious security work and leakage risk.
