Intelligent remote wireless meter reading and billing system

Abstract

The invention provides an intelligent remote wireless meter reading and billing system which comprises an intelligent electric meter, a data acquisition unit, a coordinator and a management system.The coordinator creates a wireless network with independent network identification.The data acquisition unit joins the network.The intelligent electric meter encrypts power utilization information and generates a network address containing the data acquisition unit, identification information and a power utilization information frame of the encrypted power utilization information are uploaded to the data acquisition unit, the data acquisition unit detects the sub-channel state, if a sub-channel is in a busy state, the data acquisition unit enters a sending delay state and continues to carry out detection, and if the sub-channel is in an idle state, the data acquisition unit sends a data sending request to the coordinator and sends the power utilization information frame after receiving data sending allowing information returned by the coordinator.When the coordinator receives the power utilization frame and judges arrival of sending slot time, the coordinator sends the power utilization frame to the management system, the management system decrypts the power utilization information, displays the power utilization information in real time, calculates electric charge and sends short messages containing electric charge information to users.

Description

technical field [0001] The invention relates to the field of remote meter reading and charging, in particular to an intelligent remote wireless meter reading and charging system. Background technique [0002] With the increasing demand for electricity in the society, the power supply network has spread to every corner of the city and the countryside, the number of power users is also increasing rapidly, and the number of electric meters is also increasing rapidly, which makes meter reading a heavy task. With the acceleration of the intelligent construction process of my country's power grid and the emergence of wireless sensor network technology, many medium-sized electric energy metering devices and remote meter reading billing systems based on wireless sensor networks have appeared, but the current electric energy metering device design is relatively simple, man-machine The interaction is not friendly enough. On the other hand, due to the increase in the number of data acqui...

Problems solved by technology

[0002] With the increasing demand for electricity in the society, the power supply network has spread to every corner of the city and the countryside, the number of power users is also increasing rapidly, and the number of electric meters is also increasing rapidly, which makes meter reading a heavy task. With the acceleration of the intelligent construction process of my country's power grid and the emergence of wireless sensor network technology, many medium-sized electric energy metering devices and remote meter reading and billing systems based on wireless sensor networks have appeared. The interaction is not friendly enough. On the other hand, due to the increase in the number of data acquisition devices and coordinators in the remote meter reading billing system, the collected and uploaded data continues to become huge, resulting in communication congestion and data loss, which greatly affects the power billing. Accuracy, Timeliness and Reliability
