Embodiment Construction

[0023] Embodiments of the present invention are now further described in conjunction with the accompanying drawings, but the present invention is not limited to the following:

[0024] 1. Data acquisition monitor

[0025] The data acquisition terminal of the system is mainly used to collect parameters such as current, voltage, power, power factor, variable temperature, and switch status. The input signal is output through the RS-485 interface after calculation and processing. The external communication is through the built-in RS-485 interface, and the data output protocol adopts the international standard MODBUS protocol (MODBUS communication protocol brief introduction: MODBUS protocol is a common language applied to electronic controllers. Through this protocol, controllers, controllers It can communicate with other devices via the network (such as Ethernet). It has become a general industrial standard. With it, control devices produced by different manufacturers can be con...

Abstract

The invention relates to an information remote monitoring and managing technology of electrical variables, mainly comprising a distribution transformer load data acquisition monitor of a site acquisition end, a data transmission controller and load information monitoring, dispatching and managing software of a central end, wherein the site acquisition end acquires and preprocesses parameters of load parameters, equipment operation states, and the like of a distribution transformer and outlet lines of all paths at the low-voltage side of the distribution transformer and then remotely and wirelessly transmits the parameters to the monitoring central end through a GPRS (general packet radio service) communication mode; and after the monitoring central end receives the data sent by the site acquisition end, the data is processed and analyzed through upper computer software.

Description

technical field [0001] The invention relates to information remote monitoring and management technology of electric variables. Background technique [0002] At present, some power supply systems have not installed a remote monitoring and management system for distribution transformer load information, and cannot pass first-hand data to guide on-site adjustments according to local conditions and improve power supply quality. It is also impossible to directly benefit the low-voltage distribution network, such as on-site reactive power compensation, which can improve the power factor and effectively reduce line loss. [0003] Although the power supply department spends a lot of manpower and material resources on the maintenance of power distribution equipment every year, accidents still often occur. [0004] Electric energy data collection and real-time monitoring of power grid operation status are the main work and important technical content of power supply and distribution ...
