The role of handheld terminals in the inspection work of various industries

1.  Power inspection

Power equipment inspection can effectively ensure the safety of power equipment, improve the reliability of power equipment, and ensure a minimum failure rate of power equipment. The introduction of the power inspection system has completely changed many problems in the inspection work. It does not need to install any equipment on the inspection equipment and power equipment, which greatly reduces the procurement and maintenance costs of the system; effectively ensures the inspection personnel to tour. Checking the quality, improving the safety and reliability of equipment and power equipment, eliminating potential safety hazards; using wireless networks and RFID technology to achieve information management of power equipment inspection work.
