The intelligent degree of substation is continuously improved; the equipment is updated faster. The security risk of substation maintenance is increasing gradually. In order to reduce the security risk in the maintenance work, a smart bracelet which can be used in the maintenance work of substations is designed. The bracelet mainly has functions such as heart rate monitoring, exercise detection and near-electricity alarm. Firstly, the paper designs the overall functions of the wearable bracelet and briefly summarizes the key technologies involved. Then, the chip selection, debugging and software flow design of the key functional modules such as the main control chip of the bracelet, the heart rate detection module, the fall detection module and the near power alarm module are completed. In the end, this article tests the hand ring to verify the practicability of each part of the function. The wearable device can improve the security of maintenance operations and improve the intelligence of substation safety monitoring system.
