At present, most of the cities in our country adopt the gas pipeline mode to ensure the life of residents, and natural gas is input to every household through the pipeline.However, rural heating still takes the form of coal-fired, in order to respond to the national urbanization process and improve rural living standards, the state has issued policies and means to gradually replace the rural coal-fired mode by gas, for the gas pipeline transmission mode, due to t he rapid development and wide coverage.Therefore, it is necessary to monitor the operation parameters and operation status of each gas station in real time, and adjust the gas parameters in time for the gas station with abnormal parameters, so as to ensure the stable operation of the whole system.
1. The operation data of each gas station shall be uploaded in time, the data shall be kept complete, and the overall quantitative management shall be realized.
2. Improve the overall energy utilization efficiency and increase the economic benefits of enterprises
3. Problems shall be handled in a timely manner to ensure gas supply for users.
4. Improve the matching of air supply and air demand
5. Through the analysis and processing of comprehensive parameters and data, the operation status of the whole system is judged.
The front end collects the sensor parameters such as pressure and valve gas volume of each gas station through PLC, and then sends the data to the 4G/5G industrial router through the network port. The industrial router uploads the data with the mobile Unicom Telecom Internet of Things card (SIM card), and when the 4G/5G industrial router transmits the data, once it finds that the dedicated line network is disconnected, It will actively switch to the 4G/5G private network.Carry out double backup of data link, and inform the maintenance personnel of the error report in time in the form of mobile phone short message or email, so that the maintenance personnel can carry out on-site maintenance and timely check and repair. The 4G/5G industrial router uploads the received data to the monitoring center in time, and the monitoring center analyzes, processes and saves the data in time to ensure the integrity and timeliness of the data.
1. Security
The system uploads and analyzes the data in time through the 4G/5G industrial router, handles the problem in time, and has higher data security through the dedicated line network.
2. Strong real-time performance
The 4G/5G network has the special effect of real-time online, and the delay of 5G network is smaller, and it supports multi-point transmission at the same time, so the data obtained by the monitoring center is more accurate, faster and more interactive.
3. Stability
4G/5G routers are designed with industrial standards, which can adapt to harsh environments and have stronger stability to ensure data transmission.
4. High degree of informatization
The whole system adopts advanced technology and hardware and software facilities, with a high degree of informatization, more environmental protection and energy saving, in line with the national development concept.
5. The overall economic benefit is increased
Advanced equipment and systems can find and deal with problems in time, reduce equipment maintenance costs, and monitor parameters, which can change the output and usage of gas stations in time, save more energy and achieve higher economic benefits.
