[0002] Now is the era of electrification, the operation of various instruments and equipment is inseparable from electric energy, especially in industrial production, if there is a power failure, even if relative measures cannot be taken, it may cause great economic losses, so in some important It is particularly important to set up power failure alarms in electric places. Traditional power failure alarm circuits use dry batteries as the power supply for power failure alarm circuits. As we all know, dry batteries contain a large amount of heavy metals such as lead and cadmium. Environmental pollution, and the traditional power-off alarm circuit is mostly sound and light alarm, and if the user is not nearby, the power-off situation cannot be known. With the development of the GSM network, the hardware implementation of GPRS in the alarm system has become possible
