Design of wireless anti-theft alarm for transformer

In the wireless anti-theft alarm for transformer, the human body infrared sensor, metal anti-collision inductive sensor and vibration displacement sensor are used to detect human body approaching signal, metal tool signal of dismantling transformer and vibration signal of forced moving transformer. A A/D converter is used to detect the power supply voltage to ensure the normal and stable alarm circuit system, and the multi-function button and LED display screen are set for control and maintenance. The MCU are chosen in the alarm terminal processing and the peripheral circuit are responsible for processing and displaying alarm information. Once the power transformer theft occurs, the monitoring terminal will send out sound and light warning and display alarm information to remind the staff, which can effectively prevent the power facilities from being damaged and stolen.
