摘要
This specification relates to a wireless communication device for intrinsically safe explosion proof. This specification is connected to a wireless communication unit for performing wireless transmission and reception, an external power source and the wireless communication unit, receives power from the external power source to charge electric charges, and outputs a voltage required for wireless transmission and reception to the wireless communication unit. It provides a wireless communication device including a voltage measuring unit for measuring the voltage of the super capacitor and controlling to apply the output voltage of the super capacitor to the wireless communication unit for a predetermined time when the measured voltage is within a preset reference range.
