Background
The integrated pipe gallery is an intensive tunnel built under the urban roads. It integrates municipal, electric power, telecommunication, gas, water supply, drainage, and other pipelines. Its length ranges from a few kilometers to tens of kilometers long. The inspection personnel must control and monitor the operation of the integrated pipe gallery in real-time. In order to ensure the normal operation of the pipe gallery system, it is necessary to monitor changes inside the pipe gallery, including cable temperature detection, underground water level monitoring, and manhole cover monitoring.
Difficulties
(1) Southern China has abundant rainwater and will cause puddles in lower ground, thus the measuring equipment will be submerged. It is necessary to improve the waterproof level of the measuring instrument.
(2) Since the sewage in the pipe gallery is easy to produce toxic gas, it is necessary to do underground gas exhaust before the underground operation, and master the concentration of toxic gas in the underground timely to determine the safety level of the working environment.
(3) In most pipe gallery, there is no power supply system available for the instrument, and the power supply problem of the measuring instrument needs to be solved.
(4) The signal of the underground wireless transmission system is weak, and it is necessary to ensure the timeliness of measurement data transmission.
Solution
The design concept of the pipe gallery monitoring system is to install multiple types of sensors in suitable locations according to the specific needs of monitoring. Select the solution that is most suitable for the site with low cost based on the sensor position, signal output status, power requirements, network status, etc. After the data is transmitted into the data center, the platform software will display the on-site working conditions in real-time and provide some more advanced functions through statistical analysis of historical data.
Sensing layer
The sensing layer of the pipe gallery monitoring system generally needs to measure the concentration of toxic gas, the pressure of the water supply pipeline, the underground water level, the image of the downhole, and the state of the manhole cover. The commonly used are gas sensors, pressure sensors, liquid level sensors, and variable motion sensors.
Transmission layer
The measurement data of the sensing layer is collected and transmitted to the data center through a wired or wireless network, and the Earth1006 remote monitoring terminal is commonly used to collect and transmit measurement data.
Platform layer
After a large amount of data collected into the platform layer, it needs to be classified, managed, stored, cleared, and analyzed to provide basic data support for data applications. The "Micro Sensor IoT Big Data Platform” can help users complete this work.
Application layer
Combine the user's usage scenarios and management requirements, push and customize the basic data to display the management decision basis. We provide users with customized data push, real-time notification of data through email, and other means.
Benefit
The integrated pipe gallery monitoring system is mainly based on automatic monitoring, implementing the principle of saving energy, reducing user inspections, strengthening on-site management and control, and combining with business applications. This solution helps users improve management and decision-making ability, improve overall operation and maintenance service level, and maximize economic and social benefits.
