Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] In the embodiment of the present invention, the asynchronous monitoring of a large number of Socket connections is realized by using the multiplexing listener of javaapi nio, which can solve the concurrent collection problem between the main station collection system and a large number of network tables. When collecting the data of the concentrator through the network table, the method of collecting data by packaged users is used to reduce the number of communications, improve the efficiency of communications, and save traffic. When performing supplementary collection, two supplementary collection strategies are used together, that is, the suspension of the mobile collection time pointer and the supplementary collection failure queue. integrity.

[0033] Such as figure 1 As shown, a method for collecting data from a data collection terminal includes the following s...

Abstract

The invention relates to the field of electric power and communication, which discloses a method of data acquisition from a data acquisition terminal, and the method comprises the following steps: a concentrator collects resident electricity data through low-pressure carrier waves; a net meter collects distribution transformer electricity data through alternating collection; the concentrator is connected with the net meter through a serial port, and the net meter is connected with a front end processor through a communication module and used for sending electricity data; a collection server isused for sending collection demand data to a collection terminal through the front end processor and receiving the collection terminal data transmitted by the front end processor asynchronously, if collection fails, enter supplement collection, and if not, skip to the next step; a center server is used for analyzing and processing the data. The invention simultaneously discloses a system of dataacquisition from a data acquisition terminal. The invention has the beneficial effects of high capability of permitting simultaneous access of a large number of distribution transformers and residentsand ensuring the real-time performance and integrity of resident electricity data and distribution transformer electricity data by an optimized communication method and a perfect supplement collection strategy.

Description

technical field [0001] The invention relates to the technical field of electric power and communication, in particular to a method and system for collecting data from a data collection terminal. Background technique [0002] With the transformation of the power system, the collection of power data will gradually abandon the traditional manual meter reading mode and adopt the remote terminal control meter reading method, and the meter reading data will be transmitted to the main station system for analysis and analysis through GPRS, CDMA, 230M, etc. application. In order to carry out data analysis applications and real-time monitoring of power consumption on the master station side, it is necessary to ensure the integrity of the master station side power data. Due to differences in power transmission protocols adopted by terminal manufacturers and differences in understanding of the same protocol, the complexity and instability of terminal data collection, coupled with compl...
