Xi'an non-residential measurement loss analysis and diagnosis solution.
(I) basic information
Application Scenario: Metering Management
Xi 'an * * Co., Ltd. currently has a total of more than 28000 industrial and commercial metering instruments, which adopt the IC card prepayment mode. Large industrial and commercial customers generally use turbines and Roots flowmeters, totaling about 5600. The annual gas consumption of such metering instruments exceeds 1 billion standard cubic meters, accounting for nearly 80% of the gas consumption of industrial and commercial customers. The rest of small customers use membrane meters with large flow specifications to G25. Due to the large number of tables and the large amount of gas used, there are many pain points and difficulties in daily management.
(II) Solutions
Changzhou Weige Electronics Co., Ltd. has provided a metering management system solution for the problems of Xi 'an * * Co., Ltd. According to different metering instruments and gas usage scenarios, DTU, MSU and other data acquisition units are deployed on site to collect on-site data, and then analyzed and monitored through "Intelligent Gas Management System" to realize the following functions:
1. Remote data acquisition: Collect real-time temperature, pressure, flow rate, cumulative amount and other dynamic data of metering instruments to solve the problem of difficult household copying and collection; In addition, it closely follows the development and innovation of meter technology and the management requirements of gas companies for meter parameters. For some new meters, static data collection such as meter coefficient, compression factor and deduction pulse equivalent can be realized. According to the type of meter pre-charged by Xi 'an Qin Hua, at the same time, the remaining amount of IC card, gas price and other expansion data can be collected. In some special scenes, in order to further strengthen on-site supervision, pressure monitoring data and gas leakage alarm data of industrial and commercial customers can also be transmitted to the "Intelligent Gas Management System" in real time. The timeliness collection of various data not only solves the difficulties of meter reading and high cost for industrial and commercial customers of gas companies, but also provides strong data support for gas companies in operation scheduling, scientific management and rapid response.
2. Measurement data analysis and early warningXi 'an * * Co., Ltd., as a city-burning enterprise that introduced remote transmission and control of metering instruments earlier, has established a complete data analysis system. Through the "Intelligent Gas Management System", it carries out daily data analysis and monitoring such as "single meter gas analysis", "PT extreme value analysis and early warning" and "dynamic analysis of temperature and pressure data" to timely warn the failure of mechanical rotating parts and electronic components of various metering instruments; the "logical alarm value" is set through the combination of real-time and historical data of various temperatures, pressures and flows in different states, so that the system can realize real-time intelligent early warning. Create an evaluation model for the operation status of metering instruments, quantitatively evaluate the status of metering instruments every month, and timely correct the phenomenon of measurement errors caused by the large gap between design selection and actual application. More importantly, through the "shutdown delay flow" analysis technology, it solves a big problem that city fuel enterprises are difficult to find and eliminate the "slow meter" fault of flowmeter at the gas use site, and can only find it through periodic strong inspection.
3, IC card prepaid meter and meter synchronous comparison analysis.: The trade measurement of city fuel enterprises and gas customers is based on the data in the base table, but in actual work, due to the failure or deviation of prepaid electronic functions, economic losses will inevitably be caused; In the daily management of Xi 'an Qin Hua, the accuracy of IC card deduction is checked by effectively comparing the data of IC card with the meter, and the balance monitoring of IC card account is realized at the same time, thus realizing the function of charging and payment more effectively.
4. Remote price adjustment and valve control function: To realize the rapid and remote price adjustment of IC card, the price system and price calculation mode can be directly modified, the price adjustment of IC card can be completed quickly, and the price adjustment that originally took at least one week can be shortened to several hours. In addition, the solenoid valve in the IC card table can be opened and closed in real time according to various situations.
5. Asset Management of Table ToolsXi 'an * * co., ltd. has implemented a free policy of measuring instruments to customers since March 2021. measuring instruments are incorporated into internal fixed asset management. in the smart gas management system, online control of self-storage, construction, collection, operation monitoring, re-storage, detection and secondary operation of instruments can be realized. while avoiding asset loss, asset utilization can be realized and internal management can be carried out, frequent measurement meter transfer, transfer of fixed work has brought a certain degree of convenience.
(III) main results
At present, Xi'an Qinhua Gas Co., Ltd. has 13000 industrial and commercial customers, and its production and operation scale and gas supply scale have been in the forefront of the domestic gas industry. Accurate and appropriate measurement management systems and tools for gas companies and users of fair transactions between laid a solid foundation, to avoid measurement problems caused by buyers and sellers of the transaction doubt, or even problems.
1, reduce human resources and material costs input.
2. Prevention and recovery of gas cost loss caused by metering failure
3. Reduce the failure rate of metering instruments
4. Reasonable allocation of work resources
5. Discover and avoid unconventional gas problems
Typical application cases
The washing company unloaded the meter and stole more than 620000 yuan of gas. Xi 'an's first case of gas theft was sentenced.
In April 2023, the Baqiao District Court of Xi'an City tried Zhou and other four people for theft and destruction of flammable and explosive equipment, and sentenced them to fixed-term imprisonment ranging from five years to one year in the first instance. This is the first case in Xi'an to be sentenced to a real sentence for destroying flammable and explosive equipment and stealing natural gas.
The success of this case is precisely because the Wig electronic metering management system solution used data analysis to find abnormal gas consumption, and then the on-site investigation found that users stole natural gas illegal acts, which provided data support for the gas company to recover losses in a timely manner.
