Background and challenges:

Currently, with the construction of urban gas transmission pipelines, household consumption of natural gas in 2019 was 3,550.155 million cubic meters, an increase of 13.2% over the previous year. It is expected that natural gas users will show an upward trend year by year. In recent years, my country has intensified the construction of gas transmission pipelines and the management of end users. However, for end users such as residential communities, how to conduct scientific and efficient management so that staff can fully, accurately and timely master the terminals The information of user equipment provides timely and correct solutions and gives full play to the real-time and controllability of terminal user information, which is of great significance to the realization of smart houses.

With the popularization of natural gas into households, higher requirements are put forward for the refined management of terminal equipment. With the construction of natural gas into households, relevant companies have gradually strengthened the centralized management of the gas use process in residential quarters. The management unit also hopes to have a timely and comprehensive understanding and grasp of the operating conditions of the residential quarters and on-site emergencies. Therefore, The full-time intelligent management system for residential quarters will be deployed and applied.

The main problems facing the system at this stage:

1) The accident is very harmful-due to the densely populated residential area, when accidents such as leakage occur, the response is not timely, the evacuation of people is slow, it will cause greater harm, cause a large number of casualties, and cause greater economic losses;

2) Untimely response to emergencies-when the terminal leaks, the management and maintenance personnel cannot respond in time. After the leak is discovered, personnel will be arranged to carry out emergency repairs. After a long period of time, the amount of leakage will increase and the danger will increase, causing large economic losses.

3) Slow information transmission-when the terminal leaks, the information transmission process is long and the processing process is complicated. Maintenance personnel cannot handle it in time, which will cause subsequent harm and affect the use of surrounding users.

The goal of building

In order to solve the problems of gas pipeline leakage in residential quarters, illegal operations near pipelines, terminal equipment failures, etc., it is urgent to promote the construction of residential quarters optical fiber early warning system, build complete infrastructure, integrate and collect optical fiber information data, and monitor real-time information of pipelines in residential quarters , It can send out vibration or leakage alarm in time and output the accurate position to minimize leakage hazards and economic losses.

The optical fiber early warning system uses the optical cable (single core) laid in the same trench as the monitoring medium for vibration analysis, pipeline leakage monitoring and alarm data transmission, and centralized digital information management of front and back protection devices and terminal equipment.

The construction of optical fiber early warning system must achieve the following goals:

(1) Establish a residential district information system database based on residential district pipeline layout drawings to realize the integrated management, application and maintenance of the residential district gas pipeline location information, pipeline connection information, and attribute data; provide the company's unified residential district management platform, The property dispatch platform, user use platform, alarm information push platform, emergency accident handling platform, give full play to the powerful functions of the adaptability of each platform.

(2) Realize vibration analysis and leakage analysis. Determine the vibration point or leakage point through optical fiber sensing technology, carry out multiple alarms, and push the information to relevant users, property management personnel, and emergency maintenance personnel in time through the alarm information push platform. According to the accident level, the alarm information will be fed back to the major accident To the operation and management unit and the fire and public security alarm systems to prevent the further expansion of accidents and reduce accident hazards and economic losses.

solution:

The full-time intelligent management and operation system solutions for residential quarters are mainly applied to end users and property management centers. At the same time, major alarm information is connected to operation management enterprises, municipalities, fire protection, public security and other units to avoid further expansion of major accidents and harm and safety Hidden dangers are minimized. The system structure is as follows:

Full-time intelligent operation system for residential district

The full-time intelligent management system for residential quarters fully adopts optical fiber temperature measurement and vibration measurement technology, the Internet of Things, cloud platform, and 5G application technology. Under the guidance of the design principle of "standardization, customization, and intelligence", standardized industry products are adopted to achieve The following functions:

(1) Establish a fiber optic security detection system to realize the real-time monitoring of the entire pipeline in the residential area, and at the same time connect to the gas alarm device, realize the automatic and intelligent centralized control of security, accurately judge the leakage location, and automatically make safety protection Measures to avoid subsequent hazards;

(2) Build a management platform, a dispatch platform, and a user platform, which are respectively suitable for managers, property centers, and terminal households. Different users can view corresponding data and alarm information on the client according to their own authority, and check the status of the managed area and user equipment. Intuitive display and usage status, when an accident occurs, different users can view related information in time, which solves the problem of slow information transmission;

(3) Build a push platform and emergency platform. In the event of leakage or illegal operations, the push platform will promptly send alarm information to the property center and users. At the same time, the emergency platform will notify the relevant maintenance personnel to repair as soon as possible, so that the repair response will be more Timely and efficient.

Program highlights:

The system adopts B/S architecture design and development, and the client can directly operate through the browser, providing real-time and convenient practicability of system operation. The system has the following technical performance:

(1) Convenience; the client can view the device status data through the browser at any time, and can receive the system push alarm information in time.

(2) Safety and reliability; natural gas used by end users will be safer and more reliable. The property management center and related operation management units can monitor the status of equipment and pipelines in real time, making management and monitoring more efficient and accurate.

(3) System concurrency: The system supports concurrent access of more than 100 people, and the concurrent access to a single module can support 100 people at the same time.
