Problems solved by technology

[0006] 1. Both sensors and collectors gather data to the main control room host for processing and decision-making, which is inefficient and low in redundancy
[0007] 2. The amount of wiring is large, the ancillary facilities account for a high proportion of the total investment, and the maintenance workload is large
[0008] 3. Poor functional scalability. If you want to add sensors or collectors, you need to install new wiring and communication equipment, ...

Abstract

The invention discloses a cable tunnel communication system based on a long term evolution (LTE) wireless broadband. The cable tunnel communication system comprises LTE system core network equipment, a leaky cable and a plurality of sensors. The sensors are used for acquiring state information in the tunnel. The LTE system core network equipment is connected with the leaky cable. The leaky cable transmits a wireless signal. The leaky cable is provided with grooves for improving wireless signal spreading. The sensors are in wireless communication connection with the leaky cable. The cable tunnel communication system further comprises a controller and an acquisition unit. The controller is connected with the acquisition unit. The acquisition unit is in wireless communication connection with the leaky cable. The LTE system core network equipment is in communication connection with a cable tunnel monitoring system. The cable tunnel communication system based on the LTE wireless broadband has advantages of easy application, high expandability, high signal coverage rate and high capacity.

Description

technical field [0001] The invention relates to a cable tunnel communication system based on LTE wireless broadband. Background technique [0002] With the continuous improvement of urban power load density and urban planning, the consistency requirements for transmission line corridors are becoming more and more stringent. As the highest form of laying high-voltage transmission lines, cable tunnels have been more and more widely used in the construction of large and medium-sized urban power grids due to their environmental friendliness, section transmission capacity and large number of circuits. [0003] In the high-voltage cable tunnel project that has been put into operation, at least a series of sensors such as environmental conditions, fire protection, water level, harmful gas detection, entrance and exit anti-theft and its detection will be equipped, and a number of comprehensive collection devices will be configured to collect the information of these sensors on a reg...
