Underground pipe corridor brings together various life lines of the city, concerning all aspects of the life of the citizens, is an important infrastructure for the normal operation of the city. Underground integrated pipe corridor has the outstanding advantages of convenient expansion, maintenance and repair, and is widely used in new urban areas or areas with construction conditions. However, if negligent management, there will be a variety of problems such as theft of manhole covers, water in the tunnel, failure of air quality in the tunnel, harmful gases exceed the standard, resulting in tunnel fire hazards, which affects the safe operation of power cables. Comprehensive pipeline corridor monitoring system can effectively solve the above problems, is an important means to ensure the safe operation of the underground comprehensive pipeline corridor, but also the construction of the corridor operation and management links of the top priority.
Comprehensive pipeline corridor monitoring system installs multiple types of sensors at suitable locations according to the specific needs of monitoring, and analyzes the location arrangement of sensors, signal output status, power requirements, network status, etc., to select the most suitable for the site and the lowest construction cost of monitoring box arrangement, network selection and other specific site solutions. After data collection to the data center, the real-time site conditions are visualized through the platform software, and some more advanced functions are provided through statistical analysis of historical data.
According to the sub-system classification of integrated pipe corridor monitoring system：
Integrated Equipment Monitoring System
Environmental Monitoring System
Communication System
Fire/combustible gas alarm systems
Video Surveillance System
IP Phone System
Intrusion detection system
Monitoring Center Computer System
1 Environmental Monitoring System
The environmental monitoring system realizes full monitoring of environmental parameters and status in the whole area, among which gas monitoring includes harmful gas monitoring (H2S, CO, CH4), oxygen content monitoring and flammable gas monitoring. Gas, temperature and humidity detectors are connected to the equipment collection module of this partition, and when the harmful gas content exceeds the standard or the oxygen content is too low, the system will sound and light alarm to remind the staff to take relevant measures.
There is also a need for real-time online settlement monitoring of the integrated pipe corridor, and a static level is selected for each settlement monitoring point to prevent the pipe corridor from sinking or sinking unevenly along the corridor, resulting in the breakage of the corridor pipeline.
2 Integrated Equipment Monitoring System
The integrated equipment monitoring and control takes programmable logic controller as the core to monitor and control the status of ventilation equipment, drainage pumps, electrical equipment, etc. in the corridor, and accesses equipment such as fans, smoke and fire dampers, lighting inside the corridor, float switches, pump equipment, fire doors, hydraulic manhole covers, etc. Local automatic and manual as well as remote control are available.
Control module is designed with independent CPU and can be programmed logically；
With digital input and output, analog input and output；
The control module is connected to the switch backplane by Ethernet, enabling remote status monitoring of the control and remote logic control of the output。
3 Fire/combustible gas alarm systems
Natural gas pipeline should be set up with combustible gas detection alarm system and linkage to start the accident ventilation equipment in the accident section partition of the natural gas chamber and adjacent partitions.
The natural gas corridor is set up with a fire partition at a specific distance, and methane sensors are set up to achieve online detection of combustible gases in the natural gas corridor, and over-limit alarm is equipped.；
When the flammable gas in the natural gas pipeline corridor reaches 25% of the lower explosive limit, the ventilation fans in the accident section partition and its adjacent partitions are activated.
