ZigCcc supported method for collecting data of electric energy and device for measuring electric energy

Abstract

Characters of the invention are: embedded type processor/controller of supporting ZigBee is adopted; through interface of SPI bus, radio comm. module of supporting ZigBee is connected to microcontroller; through ZigBee and gateway of isomeric network, the radio comm. module is connected to data monitor center; receiving polling, querying commands from the data monitor center, microcontroller issues commands of turning on/off power to switch relay, and transfers collected data to the data monitor center for collection and arrangement. The invention is capable of constructing network in high redundant nodes including 65000 metering devices for electric energy so as to guarantee that network possess powerful capability of data acquisition, and error self recovery capability. Thus, in condition, in which individual nodes do not work, the network can run normally. Advantages are: avoiding boring configuration procedure, reducing cost for maintaining network, manpower and time.

Description

technical field [0001] The invention relates to an electromechanical device for measuring the time integral of electric power or current, in particular to an electric energy data acquisition method and electric energy metering device supporting ZigBee. Background technique [0002] Electric energy metering, electricity bill accounting and accurate and timely collection of electricity bills are important contents of electricity management. The existing electric energy data collection is basically manual meter reading, which requires power management personnel to enter the building and enter the household, read the meter once a month or two, and then urge the user to pay the electricity bill through a computer or a hand-made electricity bill. Wrong copying, missing copying, estimated copying problems and unsafe hidden dangers. Adopting an automatic meter reading system is one of the effective ways to solve the above problems and improve the power management level of the power...

The existing electric energy data collection is basically manual meter reading, which requires power management personnel to enter the building and enter the household, read the meter once a month or two, and then urge the user to pay the electricity bill through a computer or a hand-made electricity bill. Error copying, missing copying, estimated copying problems and unsafe hidden dangers

Adopting an automatic meter reading system is one of the effective ways to solve the above problems and improve the power management level of the power system, and the wireless meter reading system is a relatively advanced meter reading method in the automatic meter reading system, such as Chinese patents CN1122388C, CN1122389C The "Electric Energy Metering Device Data Collector and Communication Method for Information Exchange Using GSM and CDMA Networks" and "Electric Energy Metering Device and Communication Method for Information Exchange Using GSM and CDMA Networks" were announced respectively. However, this wireless meter reading system Limited by the scale of GSM and CDMA network cellular communication technology, the number of users per unit area cannot be too many, which is not suitable for large-scale simultaneous collection of electric energy measurement data. Moreover, it is necessary to pay network operating costs, long-term operating costs, especially in remote When there are many Remote Terminal Units (RTUs for short), the operating costs are often difficult to be accepted by the electricity users using RTUs
