Power failure alarm and system based on GPRS network

Abstract

The invention provides a power failure alarm and system based on a GPRS network. The power failure alarm comprises a power supply module, and a GPRS module, a control module and a voltage detection module which are connected with the power supply module. The power supply module comprises a battery and a battery management unit, the battery management unit obtains a direct-current power supply for daily work from the voltage detection module and provides the direct-current power supply for each module for use, meanwhile, charging and discharging management is carried out on a lithium battery to prevent the battery from being damaged, and the lithium battery is used for ensuring that operation of the whole equipment can be maintained during power failure. The voltage detection module comprises two detection structures, namely, a U1 line detection unit and a U2 line detection unit, so that false operation signals are prevented from being sent out, and when the U1 line detection unit breaks down, the U2 line detection unit can still perform normal detection. The invention further provides a power failure alarm system constructed based on the GPRS network, so that the monitoring coverage range is enlarged, a control center and a mobile phone terminal are notified in a short message mode, and the notification is timely and in place.

Description

technical field [0001] The invention relates to the field of electric power outage monitoring, in particular to a GPRS network-based power outage alarm and system. Background technique [0002] Electronic technology has entered thousands of households, but people are paying more and more attention to the subsequent equipment and production safety issues, such as power grids, computer rooms, aquariums, automated production lines, laboratories, farms and other places that require 24-hour production lines, Communication facilities, street light lines, wire and cable anti-theft, etc. need to report to the police immediately when there is a power failure. For now, alarms have been used in every household, such as power failure alarms, sound and light alarms, shouting alarms, etc., and the power failure alarm is one of the important protection measures, but the current power failure alarm However, the monitoring coverage of the device is still relatively small, the alarm notifica...
