Field Mobility | Handheld RFID Readers for Utility Maintenance

A low-frequency (LF) RFID solution is released for use by a Guangdong utility company. The system is designed to utility maintenance workers to conduct more efficient field services with handheld RFID reader.

The solution consists of software, 125kHZ RFID tags for pipes and meters, and Chainway handheld RFID readers. Besides in utility maintenance, the solution also helps the company fight against fraud, by requiring employees to be onsite to collect data, with real-time GRS location and photo, thereby ensuring that the information is not fraudulent. 

RFID tags, each one encoded with a unique ID number, are attached to water and electricity equipment in the field. The back-end system links these tags with the attached equipment location. Maintenance services are carried out regularly. The supervisor chooses maintenance needed to be performed and assigns it to an operator. The operator receives the task on his Chainway C5000 handheld RFID reader and starts to arrange maintenance. 

Based on WinCE, this handheld terminal is equipped with high performance RFID scanner, GPS unit, high resolution camera, 3.2-inch touchscreen, physical keyboard and GPRS connection. For every maintenance task, GPS tells the operator the exact location of each equipment and selects the most suitable route for him. 

Upon visiting the site to provide utility maintenance services, the operator scans the RFID tag to enter the maintenance page. 

If the equipment maintains well, the inspector chooses the normal option, and takes a photo of it. 

If there is any problems, the inspector chooses the degree of the problem with a photo and words description. If it is severe, the operator must send the report immediately via GPRS connection on the Chainway handheld RFID reader. The back-end server receives the information in real time and the supervisor determines whether to give a long-range technical support, or to send backups. 

"This solution forces the people who have the task to take monthly maintenance operations to be really there," Chen, Chainway’s engineer reports. "The handheld’s GPS sends their location to their supervisors. Data never lies.” 

Chainway handheld RFID readers bring intelligence to utility maintenance and enable utility company to have real-time insight into the actual progress of each maintenance task.
