When the power transmission line connected with the sensitive user is powered off and the VT1 is at a low level, the control module judges that the power transmission line connected with the sensitive user is powered off, and immediately starts the short message alarm module to send a power failure short message to a control center of a power supply enterprise so that the power supply enterprise can repair the power supply enterprise in time.
In order to prevent the AC-DC isolating switch power supply module from generating faults or abnormally operating, the invention is also provided with an optocoupler U2. The optocoupler U2 can not only perform photoelectric isolation to charge a rechargeable battery, but also detect whether a power transmission line connected with a sensitive user normally has power. The invention adopts an optocoupler U2 to be connected with a rechargeable battery, a signal input end of a control module is connected with a connection part between an optocoupler U2 and a resistor R6, whether a VT2 position is at a low level or a high level is detected, if a power transmission line connected with a sensitive user is normal, the optocoupler U2 is normally conducted, and the VT2 position is at a high level, the control module judges that the power transmission line connected with the sensitive user is normal, and sends a normal power supply short message to a control center of a power supply enterprise every 10 minutes through a short message alarm module, so that the power supply enterprise can know the power supply condition of the sensitive user in real time through an active communication mechanism. When the power transmission line connected with the sensitive user is powered off, the optocoupler U2 is cut off, and the VT2 is at a low level, the control module judges that the power transmission line connected with the sensitive user is powered off, and immediately starts the short message alarm module to send a power failure short message to a control center of a power supply enterprise, so that the power supply enterprise can repair the power supply enterprise in time. When the power transmission line connected with the sensitive user normally transmits power, the optocoupler U2 is switched on, the capacitor C2 quickly discharges, when the power transmission line connected with the sensitive user is powered off, the optocoupler U2 is switched off, and the battery management unit controls the rechargeable battery to slowly charge the capacitor C2 through the resistor R6. The control module detects the charging and discharging time of the capacitor C2 to detect whether the current passes through the power transmission line connected with the sensitive user.
When the power transmission line connected with the sensitive user normally transmits power, the rechargeable battery is arranged and can be charged through the battery management unit, and the battery management unit is used for providing working voltage for the control module and the short message alarm module when the power transmission line connected with the sensitive user is powered off, so that the alarm short message can be normally transmitted. Specifically, when the power transmission line connected with the sensitive user normally transmits power, the 220V alternating current is reduced to 5V direct current through the AC-DC isolating switch power supply module, and the charging battery is charged through the TP4056 chip. The TP4056 chip can be used for protecting the rechargeable battery from overcharge and overdischarge.
