The underground pipe gallery, also known as the "common pipe ditch", is to integrate various pipelines such as municipal, electricity, communication, gas, water supply and drainage to build an intensive tunnel in the underground space of urban roads. The underground pipe gallery is as short as a few kilometers and as long as tens of kilometers, and it is impossible for the inspectors to fully grasp the operation and industrial control of the underground pipe gallery in real time. Therefore, the comprehensive monitoring system of urban underground pipe gallery environment has become the top priority of pipe gallery management.
According to the requirements of GB/T 51274-2017, the comprehensive pipe gallery needs to build a pipe gallery environment and equipment monitoring system. By arranging sensors such as hydrogen sulfide, oxygen, methane, temperature and humidity, and liquid level in the fire protection zone of the pipe gallery, real-time monitoring of harmful gases, oxygen content, temperature and humidity in the pipe gallery environment, real-time monitoring of the water level of the puddle is realized, and the linkage control of control equipment such as fans, pumps, and lighting is realized.
The integrated pipe gallery environment and equipment monitoring system is a subsystem in the comprehensive pipe gallery monitoring and alarm system, which mainly realizes the whole process of monitoring the parameters and operating status of the environment and equipment in the comprehensive pipe gallery, and the monitoring data is aggregated to the pipe gallery operation and maintenance management platform through the halo network for centralized monitoring, unified scheduling, and comprehensive operation and maintenance management.
Note: This system has many functions, including environmental and equipment monitoring system, data communication system, security system, wireless patrol system, wireless intercom system, telephone system, fire alarm system, fire door monitoring system, power supply and others, only some details are listed here, and the rest are detailed in Annex 1 "Summary Table of Monitoring Facilities and Main Materials".
The equipment layer is mainly composed of comprehensive pipe gallery environmental monitoring sensors and related control equipment, and the core equipment of this part is the comprehensive pipe gallery ACU unit, which realizes various sensor collection and equipment control. The equipment layer also includes environmental parameter acquisition sensors, such as oxygen sensors, hydrogen sulfide sensors, methane sensors, liquid level sensors, temperature and humidity sensors, etc., as well as various control equipment terminals, such as water pump control cabinets, fan control cabinets, lighting control cabinets, etc.

The system realizes the collection and monitoring of environmental monitoring sensor data deployed in the pipe gallery, and the alarm exceeds the threshold. Real-time monitoring of drainage, fans, lighting, power supply and distribution auxiliary equipment in the pipe gallery, and electricity consumption parameters.
The system realizes local manual, on-site automatic and remote control of auxiliary equipment, with local manual control as the highest priority. When an abnormality occurs in the pipe gallery, the monitoring alarm is activated, and the linkage signal is sent to the video security monitoring system. The system can realize linkage control of drainage pumps, exhaust fans, alarms, etc. according to the set threshold.
The monitoring data and equipment operation status of each pipe warehouse and partition are collected into the comprehensive pipe gallery monitoring center for unified monitoring and management through the halo network, and all kinds of monitoring data are effectively collected, classified and stored, so as to realize data analysis, centralized display and security control.
The system has the basic monitoring and management functions of the general comprehensive pipe gallery, and also covers the operation and maintenance management business of the pipe gallery, integrating disaster prevention and mitigation, emergency command and other functions. By integrating the latest technologies in the industry, such as GIS technology, the visualization and efficient operation and maintenance management of pipe gallery management are realized.
The system design adopts advanced design concepts, technologies and methods, and pays attention to the maturity of structure and equipment. The system adopts a professional geographic information system combined with GIS technology; The system function design is comprehensive and practical, and the interface design is professional and friendly.
