Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of security monitoring, more particularly, to a security monitoring system and a method thereof. BACKGROUND

[0002] With the continuous enhancement of people's safety awareness, security monitoring systems have been widely used in public places such as shopping malls, hospitals, streets, and schools. Road monitoring is mainly based on fast ball monitoring, and monitoring points are distributed at road intersections and key road sections with high traffic flow. Through image transmission channels, real-time road traffic conditions are uploaded to the road monitoring command center to adjust vehicle flow at each intersection. Traditional security monitoring systems include a support and a monitoring device. The monitoring device is placed above the lane by the support. For example, CN213512915U / CN217003879U uses a traditional vertical rod and a support rod fixed directly, and the monitoring device is fixedly installed on the support rod. When installing or maintaining such a security monitoring system, the lane must be regulated. The maintenance personnel are lifted by hoisting equipment to install or maintain the monitoring device on the support rod. If the hoisting equipment is placed at the lane, it is easy to cause traffic congestion and even increase the risk of traffic accidents, especially in the case of maintaining on the fast lane. If the rear vehicle does not observe or react in time, it is easy to cause the vehicle to hit the hoisting equipment. If the hoisting equipment is placed beside the lane, the center of gravity needs to be adjusted to prevent overturning, which increases the risk of operation for workers.

[0003] To solve the above technical problems, the existing solutions are to movably connect the vertical rod and the support rod. For example, patent technologies CN216590638U and CN209762618U slidably connect the support rod to the vertical rod, and CN215210654U rotatably connects the support rod to the vertical rod. When maintaining the security monitoring system, the support rod is rotated to the side of the lane and lowered to a certain height. Considering that lowering to the height directly for maintenance may increase the risk of collision injury to pedestrians, a lifting device is generally used to lift the maintenance personnel for maintenance, making the maintenance operation of the security monitoring system complicated and the risk difficult to be effectively reduced. SUMMARY

[0070] In order to further improve the connection stability between the second threaded hole 402 of the sliding block 4 and the second screw rod 301, referring to Figure 12 and Figure 13 , the sliding block 4 further comprises a gap 403, a first sliding groove 407 and a second sliding groove 408, the gap 403 is arranged on one side of the second threaded hole 402, the gap 403 is a U-shaped groove structure, the first sliding groove 407 and the second sliding groove 408 are V-shaped structures, the first sliding groove 407 is adapted to slide with the vertical rod 101, and the second sliding groove 408 is adapted to slide with the support rod 102.

[0071] In the technical scheme, the gap 403 with a U-shaped structure is arranged at the end of the sliding block 4 close to the second screw rod 301, when the sliding block 4 slides to the end of the second screw rod 301 and the end is located inside the gap 403, the shaft rod 406 slides to the farthest corner along the horizontal groove side of the guide groove 107, at this time, the first threaded hole 401 is located directly above the first screw rod 201, and the first threaded hole 401 of the sliding block 4 is threadedly connected with the first screw rod 201 under the action of gravity, so that the sliding block 4 can realize vertical sliding.

[0072] Since the threaded part of the end of the second screw rod 301 is threadedly connected with the threaded part of the inner wall of the gap 403 in this state, when the sliding block 4 moves from bottom to top and is separated from the end of the first screw rod 201, the shaft rod 406 slides to the farthest corner along the vertical groove side of the guide groove 107, and can be threadedly connected with the second screw rod 301 through the thread on the inner side of the gap 403, so that when the second screw rod 301 rotates, the sliding block 4 can move to the right.

[0075] In the above embodiment, the power cable is wound in the inner wall of the base, and during the descending and sliding of the stand 101 and the camera 5, the power cable is likely to be squeezed and even tangled, causing damage to the line and making it impossible to supply power to the camera 5. Therefore, the cable can be wound in the base and the stand 101 respectively to reduce the mutual squeezing of the cables, but the cable is likely to be damaged under the action of long-time lifting and stretching of the device. Although the service life can be prolonged, the cable damage cannot be avoided, and the segmentation of the cable increases the difficulty of detecting and judging the fault position during maintenance. To solve the above defects, the two-section distributed cable is designed (not shown in the figure):
