On-site mobile terminal application for electricity meters in Taiyuan power supply system

Thread Content

It is reported that this is a \"field mobile work terminal device for electricity meters\" developed and applied first in Shanxi Province by the company using modern information and automation technologies. It reduces the workload, which previously required 20 people to work for over 10 hours per meter, to just a few seconds, while also significantly improving accuracy and precision. Electricity metering devices are the fundamental computing equipment in the transaction of electric power products, and they are directly related to the quality of power supply services. Previously, when installing electricity meters, staff had to manually enter the 22-digit bar code, which was 5 centimeters in size, on a form; after filling out the ‘Electricity Meter Installation/Removal Form’, they would then enter the information item by item into the marketing management system. Due to the large number of personnel involved and the complex processes, it is easy to encounter issues such as data entry errors and lost work orders. Once an error occurs, it not only increases the amount of repetitive work but also results in a mismatch between customer information and meter codes, causing losses for both the company and the customers. To this end, Taiyuan Power Supply Company conducted an in-depth analysis of the problems that arise during the installation of meters, established a specialized research team, and developed the \"On-site Mobile Work Terminal Equipment for Electric Energy Meters.\" This device employs a \"two-way data entry and remote transmission\" approach: customer application details are entered into the terminal device through the marketing system. After the staff install the meters on-site, they retrieve the customer information from the terminal device, press the scan button, and the terminal device uses infrared technology to scan the barcode on the meter. The data is then transmitted remotely via wireless network back to the marketing system, resulting in accurate customer records. This eliminates the need for multiple steps such as handwriting, filling out forms, and data entry, improves the accuracy of meter data, and provides an accurate basis for the company to keep track of meter usage as well as for customers to monitor their electricity consumption at any time. ‘The use of on-site mobile terminal devices for electricity meters ensures a 100% accuracy rate in matching customer information with the meters, and it is expected to save approximately 1 million yuan in labor costs each year.
