Prepayment electricity consumption control system based on step electricity price

Abstract

The invention relates to a prepayment electricity consumption control system based on step electricity prices, which comprises a remote controller, a plurality of prepayment electronic electric energy meters, an electricity selling machine, a wireless multi-hop concentrator and an upper computer, wherein the remote controller is transmissively connected with the electronic electric energy meters or the electricity selling machine through infrared rays; and interfaces on the box body of the electricity selling machine is connected with the communication interfaces of the upper computer through data lines, the first serial interface of the upper computer is connected with a GPRS (General Packet Radio Service) module, the GPRS module is transmissively connected with the wireless multi-hop concentrator, and the wireless multi-hop concentrator is respectively and transmissively connected with the prepayment electronic electric energy meters with an NRF905 wireless communication module respectively through a wireless multi-hop network. The prepayment electricity consumption control system based on step electricity prices has the advantages of scientific, reasonable and creative design, high flexibility, great convenience and high operability in electricity sales, high operation accuracy and the like which are not owned by the conventional electricity sales methods. Moreover, the prepayment electricity consumption control system based on step electricity prices additionally has the advantages of improved electricity selling efficiency, higher practicability, compact overall structure, small material consumption, long service life, low cost, stable and reliable performance and convenience in maintenance, and can be widely popularized and used by power departments.

Description

technical field [0001] The present invention relates to a control and management system, in particular to a digital, intelligent and networked control and management system for step electricity price pre-charging based on infrared remote control technology used in power systems. Background technique [0002] At present, energy shortage and environmental pollution have become the main contradictions restricting the sustainable development of economy and society. Implementing a tiered electricity price policy for residents' electricity consumption is one of the important measures taken by many energy-deficient countries to deal with rising energy prices and curb unreasonable energy consumption. In my country, the full implementation of tiered electricity prices for residents mainly considers the establishment of mechanisms in three aspects: First, a reasonable electricity price mechanism. Users with higher voltage levels have lower power supply costs; users with lower ...
