Remote electric quantity data automatic acquisition control system

Abstract

A remote electricity data automatic collection control system includes a site terminal electricity collection system and a master station system exchanging data by short information of GSM network. The site terminal electricity collection system includes a user multifunction electronic energy meter, a site terminal electricity collector and a first send/receive antenna. The master station is a customer/server network structure including a master station data centralized converter, a computer and a second send/receive antenna. Said system utilizes the short message function of GSM cellular digital radio communication system to realize the collection and data transfer of site data volume and switch.

Description

technical field [0001] The invention relates to a remote electric quantity data collection and control system, in particular to an automatic remote electric quantity data collection and control system. Background technique [0002] With the continuous deepening of my country's economic reform and the rapid development of the market economy, the power system has undergone tremendous changes in terms of institutional structure, ideology, operation management, and technological progress. People are more aware that science and technology are the primary productive forces, and scientific and technological progress can bring greater economic benefits. Today, with the continuous improvement of people's living standards and the continuous economic development of all walks of life, the demand for electricity is also increasing. It is even more necessary to strengthen the monitoring and management of distribution networks and power grids to improve the economic benefits of the power s...

Problems solved by technology

[0008] 1. High hardware cost

Because the on-site remote terminal data acquisition device collects, calculates, processes and accumulates all the on-site data into the device, the device is more complicated and the hardware cost is higher

[0009] 2. Safety and reliability are limited

When the on-site remote terminal acquisition device fails, it may lead to the loss of all data previously stored in the device

[0010] For example: the general FLASH device takes a long time to write (about 5-10ms), and the number of writes is limited (as the number of writes increases, its service life is shortened, and the general service life is about 100,000 times), such as every 5 minutes Collect and save data once for calculation, the device will reach the end of its service life after about one year of operation, if the device is damaged, all data will be lost, resulting in paralysis of the entire device; using a RAM device with a lithium battery inside, one is that the device The cost of the device is relatively high. The market price of a 4K MB RAM device is around 1,800 yuan. Second, it is susceptible to interference, especially when the power is turned on or off, and the data stored in it may be washed out and lost.
