Problems solved by technology

[0003] At present, the construction of similar systems is aimed at different terminal uses, and is generally provided by one or more terminal manufacturers. It lacks support for standard and open communication protocols, and there are barriers to entry for other terminals, which limits the development of terminal technology.
Difficulties in data sharing between various systems, serious file inconsistencies and data islands, greatly reducing the role of the master station system in management analysis and load forecasting

Embodiment Construction

[0015] Such as figure 1 The shown integrated terminal access architecture based on the communication protocol adapter includes: a terminal equipment layer, a communication layer and an application layer, and the terminal equipment layer, the communication layer and the application layer are based on the SOA architecture from bottom to top set, and the layers are connected by message passing.

[0016] In order to reduce the technical barriers to access, the communication layer supports the required communication methods according to the communication methods supported by the terminal and the communication links that each power supply company can provide. The communication methods that need to be supported include: GPRS, CDMA, 230 radio, dial-up mode, network dedicated line, serial dedicated line, SMS, etc. The above communication methods can be divided into network communication and serial communication in terms of link types. Belonging to network communication methods includ...

Abstract

The invention discloses a communication protocol adapter-based integrated terminal access system structure, which comprises a terminal equipment layer, a communication layer and an application layer, wherein the terminal equipment layer, the communication layer and the application layer are arranged in turn from the bottom to the top based on SOA architecture, and connected in a message transmission mode. Further, the communication layer comprises a link abstraction layer for shielding data transmission differences of various communication channels and a communication protocol layer for shielding differences of various protocol type acquisition terminals. Furthermore, an adapter of the communication protocol layer is connected with the application layer through multiple communication protocols. The structure realizes integration of single main stations so that the initial constructed professional system can conveniently perform data integration and application integration; and the initial invested field equipment can be completely and effectively connected to a new system, so repeated investment is avoided.

Description

(1) Technical field [0001] The invention relates to an integrated terminal access architecture based on a communication protocol adapter, which belongs to the technical field of computer networks. (2) Background technology [0002] At present, there are more than 30 terminals for demand side management of Shandong electric power, such as Hangzhou Hualong, Shenzhen Kelu, Jicheng Electronics, Qingdao Hi-Tech, Shenzhen Haoningda, Shanghai Synergy, and Qingdao Bright. The protocols adopted by various types of terminals include "Shandong Electric Power Group Company Electricity Field Service and Management System Communication Protocol", "Power Load Control System Data Transmission Protocol (96 Edition)", "Power Load Control System Data Transmission Protocol (2004 Edition)" , "Power Load Control System Data Transmission Protocol (2005 Edition)" and other regulations promulgated by many ministries and provincial units, as well as "Communication Protocol between YCC Concentrator an...
