Background
Nowadays, a growing number of industries have embraced new digital technologies. There is no exception for power sector. At present each substation box is equipped with a key-based padlock and all keys are kept in the same place. It's easy to imagine that locks and keys are lost or mismatched time and again. There exist risks as padlocks can be easily picked. Besides, administration team can’t effectively record maintenance time and detailed operations.
Challenges
Mechanical locks and keys are easy to get lost or stolen. Power equipment may be accessed to by the unprofessional, being a potential safety risk.
Paper records cannot be well kept. It is also quite inconvenient to track previous records.
It is almost impossible to trace the person in charge if incident happens.
Solutions
Determined to place everything in order, Everlink decided to collaborate with Chainway. C71 mobile computers are customized to be part of the solution as well as electromagnetic locks. Each time during inspection and maintenance, field workers need to read the RFID tag attached in the substation box, then log in with his username and password in an app to open the box automatically. After maintenance is done, lock it directly on C71 handhelds. The backend server syncs maintenance time, personnel and equipment number for future check.
Effects
It turns out to be convenient and efficient when using C71 mobile computers to open and lock electromagnetic locks.
When field workers log in the app, their identity and maintenance operation can be matched and recorded automatically. It is easy to trace and track if workers misbehave.
Maintenance records synced to the backend server make it possible for administration team to learn substation status in real time.
In general, Everlink Substation in Yantai, Shandong is heading for digitization and scientific management.
