一种用于居民费控表短信通知缴费的装置A device for notifying payment by short message of resident fee control meter

【技术领域】【Technical field】

本实用新型涉及一种用于居民费控表短信通知缴费的装置,具体涉及一种能够实现同时对多个费控电能表的剩余金额、剩余电量等指标进行在线实时监测并在达到报警门限值的情况下向居民用户发送充值短信提醒的终端装置。The utility model relates to a device for notifying payment by short message of a resident fee control meter, in particular to a device capable of realizing online real-time monitoring of indicators such as the remaining amount and remaining power of multiple fee control electric energy meters at the same time and when the alarm threshold is reached A terminal device that sends SMS reminders for recharge to resident users when the value is exceeded.

【背景技术】【Background technique】

随着近几年我国电力体制改革的深入和大中城市配网改造工程的成功实施,供电体系必须进行一系列的自动化和智能化改造,以保证配输电系统能够高效、公平、便捷的为电能使用者提供优质服务。但目前基层单位的电能表由于采用表箱集中式安装,在电能表剩余金额达到报警门限时,电能表背光报警无法及时有效的通知到居民用户。With the deepening of my country's power system reform in recent years and the successful implementation of distribution network transformation projects in large and medium-sized cities, the power supply system must undergo a series of automation and intelligent transformation to ensure that the power distribution and transmission system can provide electricity efficiently, fairly and conveniently. Provide users with high-quality services. However, due to the centralized installation of the electric energy meters in the grass-roots units, when the remaining amount of the electric energy meter reaches the alarm threshold, the backlight alarm of the electric energy meter cannot notify the residential users in a timely and effective manner.

上述问题会导致:一、用户在不知道自己的电费余额不足的情况下,被电力公司强行切断电力供应;二、电力公司需要派专人前往小区催费。强行切断电力,容易使电力公司和用户产生民事纠纷。而对于那些电表安装位置比较分散的地区进行人工催费则会浪费大量的人力资源,并且实时性也较差。The above-mentioned problems will lead to: 1. The power company forcibly cuts off the power supply of the user without knowing that his electricity bill balance is insufficient; 2. The power company needs to send a special person to the community to urge the bill. Forcibly cutting off the power will easily cause civil disputes between the power company and the user. However, for those areas where the installation locations of electric meters are relatively scattered, manual reminders will waste a lot of human resources, and the real-time performance is also poor.
