Underground utility tunnel region controller and work method thereof

Abstract

The invention discloses an area controller of an underground integrated pipe gallery and a working method thereof, including: an environmental data collection step: using the area controller of the underground integrated pipe gallery to realize the collection of the internal environment data of the underground integrated pipe gallery; and the linkage control step: the underground integrated pipe gallery The regional controller processes the collected environmental data to realize on-off control of the fan or water pump; fault detection steps: use the regional controller of the underground comprehensive pipe gallery to realize the fault detection of each sensor. The invention can realize the monitoring of the environment in the pipe gallery.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to an area controller of an underground comprehensive utility gallery and a working method thereof. Background technique [0002] The urban comprehensive pipe gallery integrates various engineering pipelines such as power, communication, heat, water supply, etc., providing a safe and stable carrier for the normal operation of the city, and is the "lifeblood" to ensure the stable operation of the city. Various signal lines, gas pipes, heat pipes, water supply pipes, communication pipes, power pipes, etc. are erected in the underground comprehensive pipe gallery. It is an underground space integrating various transmission objects. In order to ensure the safe and stable operation of the pipe gallery, It is necessary to monitor the environment inside the pipe gallery in real time, and at the same time be able to automatically respond to abnormal environmental infor...

AI Technical Summary

Problems solved by technology

PLC has the following deficiencies: 1. Since its internal linkage control logic requires professional PLC developers to program and implant, the technical threshold for PLC equipment is high, and the control logic does not support remote modification; 2. The communication between PLC and the host computer passes The wired network of TCP / IP protocol, the communication distance cannot exceed 100 meters, and it relies heavily on the network; 3. The cost of equipment is generally high, and the volume is large, which occupies a lot of space in the pipe gallery

[0004] At present, there is also a kind of equipment on the market that can realize the data collection of sensors in the pipe gallery and equipment control. It is based on RS485 and TCP communication for data collection, and the collected original data packets based on the MODBUS protocol are directly sent to the host computer, and No data processing is performed; the status monitoring and start-stop control of water pumps, fans and other equipment are remotely detected and controlled through DI and DO switching signals; there are some shortcomings in this method: 1. Data acquisition and remote equipment control are separated 2. The collected data cannot be analyzed, but the data is directly sent to the upper computer for processing, which greatly increases the processing pressure on the upper computer; 3. It is impossible to realize automatic control, and the upper computer can only be based on the collected data. The data is used to judge whether to start and stop water pumps, fans and other equipment; 4. There is a single point of failure risk of the upper computer. If the upper computer fails, the collector and controller connected to it will not work normally

5. Data acquisition and equipment control are not on the same controller, and there is no logic processing capability, so automatic control cannot be realized
