Visual monitoring and shooting system and method for cable tunnel video

Abstract

The invention discloses a visual monitoring and shooting system and method for a cable tunnel video. The system comprises a monitoring device and shooting which is used for collecting video information of a cable tunnel and identifying a person entering the tunnel based on a face picture of the person entering the tunnel in the video information; the cable sheath damage condition and the surface water accumulation condition are judged based on visible light pictures in the tunnel in the video information, a cable sheath damage notice is issued, and the water accumulation position and water accumulation information are marked on a GIS map; the system also comprises a power supply module connected with the monitoring and shooting device; the power supply module comprises at least one charging circuit, each charging circuit is connected in series with a preset number of charging management chips which are connected in parallel, and the charging management chips are connected with a microcontroller; and the microcontroller is used for controlling the starting number of the charging management chips according to the capacity of the corresponding energy storage element in the power supply module, and controlling the starting and stopping of the corresponding charging management chips according to the current temperature of the charging management chips, so that the time-sharing heat dissipation of the charging management chips is realized.

Description

technical field [0001] The invention belongs to the technical field of video surveillance of cable tunnels, and in particular relates to a system and method for video visualization surveillance of cable tunnels. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The power supply system of the existing visual monitoring system for cable tunnels uses induction to take power or lays a dedicated power supply line. The inventor found that the following problems exist in the existing visual monitoring system: [0004] (1) The existing visual monitoring system cannot dynamically adjust the running quantity and dynamic heat dissipation of the charging management chip according to the real-time operation status of the charging management chip, which leads to the slow charging process of the visual monitoring system and affects the normal operation of...

AI Technical Summary

Problems solved by technology

[0004](1) The existing visual monitoring system cannot dynamically adjust the running quantity and dynamic heat dissipation of the charging management chip according to the real-time operating status of the charging management chip, resulting in a visual The charging process of the monitoring system is slow, which affects the normal use of the visual monitoring system

[0005](2) The current visual monitoring system takes pictures at a fixed time interval. If the shooting time interval is too long, the real-time performance is very poor, and it is impossible to analyze the situation on the spot. There is a continuous understanding; if the shooting time interval is too short, the power consumption of the system will be much higher, so that the sudden situation of the cable tunnel site cannot be obtained in real time only by image acquisition

[0006](3) At present, the ground water in the tunnel is sensed by the water level sensor and drained by the water pump; How long does it take to discharge the accumulated water? It is impossible to have a visual perception of the accumulated water, and it is necessary to manually confirm the water condition on the spot; and at present, the damage to the cable sheath is mainly based on the vibration optical fiber to determine whether the cable has vibrated, and it is impossible to judge whether the cable has been damaged and Check for damage
