Embodiment 1

[0042] Such as figure 1 , a method and system for online collection and monitoring of energy metering data, mainly composed of three parts: smart meters, collectors, and management centers, and its functions mainly include: data copying, data transmission, data storage and cleaning, automatic time calibration, parameter Query and setting, event record, security protection.

[0043] 1. Data copying: data copying mainly includes three methods: real-time copying, timing copying, and automatic supplementary copying. Real-time copying requires that the data collector can read the status information, related data and time parameters of the designated collection point at the designated time in response to the requirements of the management center. Timing reading refers to periodic automatic reading according to the parameters set by the management center. When the meter reading time and meter reading cycle are determined, the system will automatically read all kinds of data from the...

Abstract

The invention discloses an online collecting and monitoring system of energy measuring data, which is composed of two parts, wherein the one part is a hardware platform centered by a MCU control module, and the other part is a management center platform centered by a master station; the management center platform can remotely manage the collector through a GPRS module, the hardware platform can perform data collection on an intelligent meter by 485 method and a wave carrier method and report to the management center; the online collecting and monitoring system is characterized in that the hardware platform comprises an embedded controller circuit, an RS-485 communication circuit, a GPRS communication circuit, an electricity carrier wave communication circuit, a clock circuit, a display circuit, a power circuit, a keyboard input circuit, a JTAG debugging circuit and a storage circuit; the collector adopts two communication methods totally, and two communication methods carry out the data communication by a serial port; the RS-485 communication circuit can modulate the signal to be symmetrical form so as to carry out signal transmission in the manner of balance sending; then the signal is received by a differential way; a half-duplex operation mode of master and slave structures is adopted.

Description

technical field [0001] The invention belongs to the technical field of automatic instruments and relates to energy data collection. The system is especially suitable for data collection, analysis and control of electricity consumption information. Background technique [0002] In recent years, many countries at home and abroad are vigorously developing the research and development of electric power information collectors, and its development can be described as rapid. In our country, there are many ways to realize electric energy data collection and data management. The current collection scheme and management mode are all phased products born in specific scenarios. The success rate, accuracy rate, and real-time performance cannot be reliably guaranteed, and the scope of application is also limited. Therefore, it is of positive significance to realize a convenient, efficient, intelligent, real-time and stable power information collector. [0003] There are also patent appl...
