Embodiment approach

[0071] The power data acquisition and remote transmission system based on the GPRS communication module is mainly aimed at the acquisition and transmission of power data in power plants. The purpose is to solve the problem that some power plants cannot realize wired transmission, which can not only solve practical difficulties, but also save management costs. The embodiments of the invention are as follows:

[0072] Its hardware platform adopts the commonly used network connection, modularization, integration and data distribution processing system structure. The power collection concentrator 2 is generally a historical station or an engineer station of the DCS system of the power plant, and is mainly responsible for extracting the required power data from the DCS system.

[0073] There are two ways for data interface connection: one is serial RS-485 mode, RS-485 adopts balanced transmission and differential reception, so it has the ability to suppress common mode interference...

Abstract

A GPRS wireless data transmission mode is provided. A server is disposed in a server cabinet. The server cabinet includes a cabinet body. A vertical panel of the cabinet body is subjected to impact molding to form a sealed cell body defined by the vertical panel and same with the cabinet body. The vertical panel of the cabinet body is provided with cut-through slots. A cover plate is hinged to theexternal wall of the vertical panel of the cabinet body and covers the cut-through slots. Integer variables are in one-to-one correspondence with GPRS communication modules. After data received are packaged by the GPRS communication modules to form data packages and the data packages are sent to the server, a data package counting and calculation program calculates the number of the data packagessent by the GPRS communication modules to the server and the number is adopted as a current value. A defect that tasks of substrate management controllers are increased and the substrate management controllers can't bear the heavy load because a large amount of messages are sent to the substrate management controllers in short time due to abnormal servers in the prior art is effectively avoided by the mode.

Description

technical field [0001] The invention relates to the technical field of GPRS, in particular to a GPRS wireless data transmission mode. Background technique [0002] In terms of power management and control, most power generation companies are still limited to the display level of superficial data, lacking scientific theoretical model support. There are many types of units in power generation enterprises. Under different working conditions, the steam extraction, heat supply and unit output restrict each other. The traditional means of controlling the production status of power generation enterprises are single, and most of them are reported manually. It is difficult to guarantee the real-time, high efficiency and accuracy of data, and it is impossible to make timely adjustments for some emergencies of power generation enterprises, which affects the quality of power supply. [0003] With the rapid development of computer technology, how to efficiently obtain the operating stat...
