Prepaid electricity using control system based on wireless multi-hop network

Abstract

The invention provides a prepaid electricity-utilization control system based on a wireless multi-hop network, which comprises a remote controller, a plurality of wireless prepaid electronic electric-energy meters, an electricity-selling machine, a wireless multi-hop concentrator and an upper computer. The remote controller communicates with the wireless pre-payment electronic electric-energy meters or the electricity-selling machine by means of the infrared rays. The interface of the electricity-selling machine is connected with the communication interface of the upper computer. The serial interfaces of the upper computer are interconnected via a GPRS module. The GPRS module communicates with the wireless multi-hop concentrator. The wireless multi-hop concentrator communicates with the plurality of wireless pre-paid electronic electric-energy meters respectively via a NRF905 wireless communications module. Compared with the prior art, the prepaid electricity-utilization control system has the advantages of scientific and novel design, good flexibility and accessibility in selling electricity, easy use and accurate operation. Additionally, the prepaid electricity-utilization control system has the advantages of high electricity-selling efficiency, strong practicability, compact overall structure, low material consumption, long service life, low cost, stable and reliable performance, and convenient maintenance; and is applicable to the promotion and application in electric power sectors.

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 pre-charging electricity charges used in a power system based on wireless multi-hop network technology. Background technique [0002] At present, there are three main types of electric energy meters used by rural electricity consumption and power supply business departments: one is the traditional rotary mechanical electric energy meter, which is the most commonly used one at present. The disadvantage is that the accuracy is not high and it is difficult to realize the digital function. A kind of energy meter facing elimination. The second category is the electronic energy meter, which is a relatively advanced energy meter currently used. It is characterized by the use of an application-specific integrated circuit, which improves the measurement accuracy and reliability, but because there is no CPU, it...
