The invention discloses a message reminding device for prepayment excess. The message reminding device comprises a power supply module, an arrearage state collecting module, a microprocessor and a wireless communication module. The power supply module is connected to a mains alternating current power and used for gaining access to the same and outputting low-voltage direct current, powering the microprocessor and the wireless communication module. The microprocessor and the wireless communication module are connected with the power supply module. The arrearage state collecting module is connected with both the microprocessor and a monitored energy meter. The arrearage state collecting module comprises a resistor R4, a resistor R5, a capacitor C200 and an optical coupler U206. The message reminding device has the advantages such that the user is timely reminded of the arrearage state through the messages, and residents' lives are not disturbed.
Description
technical field [0001] The invention relates to a prepaid over-quota short message reminding device, in particular to a prepaid overquota short message reminding device for electric energy meters. Background technique [0002] The alarm device of the traditional prepayment device uses a buzzer alarm to remind customers to recharge the electricity bill in time. After years of operation, it is found that the buzzer alarm has shortcomings in use: 1) The alarm device works continuously, There is a phenomenon of disturbing people in the middle of the night; 2) The beeping sound is similar to the alarm sound, causing misunderstandings in daily life; 3) Some prepaid devices are far away from the client, and the beeping sound cannot be heard, resulting in power outages due to arrears. Contents of the invention [0003] In order to avoid the disadvantages in the above-mentioned prior art, the present invention provides a prepaid over-quota short message reminder device, which remin...
