Problems solved by technology

[0004] The traditional tunnel environmental monitoring adopts the active monitoring method, which requires an external power supply to provide power for the environmental monitoring sensors. For tunnels with long distances, multiple monitoring points and multiple power supplies are required, which greatly increases the workload of operation and maintenance personnel. burden

Abstract

The present invention discloses a cable tunnel environment detection device and method. The device comprises the environment monitoring devices and a rail patrolling and inspecting dolly, the environment monitoring devices are arranged on the wall of a cable tunnel, and the rail patrolling and inspecting dolly is arranged on a rail in the tunnel, patrols and inspects the environment monitoring devices arranged on the wall of the cable tunnel, does not stay more than 2 minutes at each environment monitoring device and is used to collect the tunnel environmental data acquired by the environmentmonitoring devices. The cable tunnel environment detection device and the cable tunnel environment detection method of the present invention monitor a cable tunnel environment, analyze the cable tunnel environment comprehensively and warn early according to the analysis data, have the characteristics of being high in detection sensitivity and accurate in reliability, and are specially suitable forbeing applied to the cable tunnel that cannot provide an external power supply, and is longer in tunnel distance and many in monitoring points.

Description

technical field [0001] The invention relates to the field of cable tunnel environment detection, in particular to a cable tunnel environment detection device and method. Background technique [0002] The application of cable tunnels meets the requirements of high load density and cable-based power supply in urban areas, can effectively guarantee the transmission capacity of power channels, and at the same time improve the utilization rate of channel resources. [0003] Power cables are generally composed of conductors, insulators and thermal sheaths. Cables in operation cannot exceed the upper threshold, otherwise it will cause power interruptions and cause fires; because the cable tunnel is located underground, the ventilation conditions are not good, and groundwater seeps in, making The humidity in the cable tunnel increases, which affects the normal operation of power equipment; there are often cracked gas in the cable tunnel, which will cause great harm to the health of ...
