Background

The existing prepayment device is mainly used for reminding a user of purchasing electricity by additionally arranging a buzzer and an alarm lamp in a box body, and the device can stop alarming only when the read electricity is higher than an alarm threshold value after the user reads new electricity purchased by charging and purchasing a card. Along with the popularization and use of the prepayment device, some problems to be solved urgently are derived, and because the installation site of the prepayment device is mostly not close to the activity range of factory population, the alarm effect of partial users reflecting the original self-sending of the prepayment alarm device is not obvious, so that the prepayment device has insufficient balance power failure for many times, and the production and the life are influenced.

In order to solve the above problems, chinese patent CN207458219U discloses a wireless alarm system for prepaid electricity selling devices, which includes an intermediate relay, a wireless transmitter, a wireless receiver and an alarm element, wherein a control end of the intermediate relay is connected with a controller of the prepaid electricity selling devices, an input end and an output end of the intermediate relay are respectively connected with two ends of a trigger switch of the wireless transmitter, an output end of the wireless receiver is connected with the alarm element, and the wireless transmitter and the wireless receiver establish a wireless connection. The alarm element can be arranged in an electrician duty room, so that the balance of a user is effectively prompted to be insufficient or reach a threshold value, and the problem that alarm information of the alarm element is not obvious is avoided.

However, the existing scheme has a defect that after the alarm is given, a music doorbell or a buzzer sounds, and the alarm device forgets to pay after a silencing switch is manually pressed, so that the reliability of the alarm device is reduced, and the reminding effect is greatly reduced; in addition, if the alarm device has a fault and false alarm or does not alarm, the user experience can be seriously influenced.
