Embodiment Construction

[0032] Combined with the accompanying drawings, the main work flow of the system and the mutual calling relationship between each functional module are described. The work flow of the system is as follows: figure 2 As shown, after the system is started, the system configuration management unit reads the local system configuration item information, and completes the initialization operation of the public data unit. Then start the communication management unit and wait for the connection request from the data collector. Once the connection request from the collector is received, the connection scheduling management unit will read the TCP connection identifier generated by the operating system, and at the same time the communication management unit will establish data communication based on network flow Channel, the network stream data channel realizes the sending and receiving of data by writing data and reading data, and then the communication management unit writes the channel...

Abstract

Disclosed are a method and a device for realizing data acquisition services of a renewable energy source monitoring system. The method is characterized by including the following steps: system configuration management, public data cache, log processing, communication management, data storage, data safety processing and UI (user interface) interaction, wherein the step of communication management is mainly used for completing communication processing process between the system and a data acquirer and has functions of managing connection of client sides, analyzing received data, communicating with and responding to the data acquirer and the like. By the aid of the method, performance and resources of the renewable energy source monitoring system can be optimized, so that the system can stably run for a long time.

Description

technical field [0001] The invention relates to a data collection method, in particular to a method for realizing the data collection service of a renewable energy monitoring system. Background technique [0002] Normally, the server for data communication based on the TCP protocol can use the following two schemes to design the server software. Solution 1: Use multi-threading technology to open a thread for each client connection (that is, connection socket), so as to ensure the timeliness of the server. Analysis: Although the timeliness of the server has been improved by using multi-thread processing, once there are a large number of client connections (possible in engineering practice), the server will open a large number of threads for processing, which will inevitably affect server performance. Very high requirements; once the client connection is accidentally disconnected, if the thread resources that have been opened are not recovered in time, it will cause a great w...
