Method for supporting hot plugging of intelligent acquisition terminal

Abstract

The invention discloses a method for supporting the hot plugging of an intelligent acquisition terminal. The method comprises a terminal agent, a management server and a database, wherein the terminal agent is arranged and run in the intelligent acquisition terminal, and is used for automatically sending a hold request which contains four fields, namely a request code, a terminal identity (ID), amaximum acquisition time interval and a terminal address to the management server; a terminal information table is maintained in the database, and each record in the table comprises the following fields: the terminal ID, a life cycle and the terminal address corresponding to one intelligent acquisition terminal; and the management server receives and processes the request of the terminal agent, completes an addition action, maintains all information in the table, and performs delete operation according to the life cycle field in the terminal information table simultaneously. By the method, a remote intelligent acquisition terminal can be dynamically added and deleted in a supervisory control and data acquisition (SCADA) system so as to save the conventional complex manual update operation.

Description

technical field [0001] The invention relates to a management method for an intelligent collection terminal in a data collection and monitoring control system, in particular to a hot plugging method for an intelligent collection terminal. Background technique [0002] Data acquisition and supervisory control (SCADA) systems are widely used in industrial production, power systems and other fields. In a typical application environment, dozens to hundreds or even thousands of intelligent acquisition terminals are often required to collect data on site. Therefore, how to efficiently and conveniently manage these intelligent collection terminals is a problem that needs to be considered. [0003] At present, a complete and mature solution for the automatic management of intelligent collection terminals has not yet been formed, and it is mainly carried out manually and statically: first determine the number of required intelligent Once the address or terminal ID is established, th...

Problems solved by technology

[0004] This static management method is closely integrated with the application program, and there is no relatively independent management module to complete the addition and deletion management of intelligent collection terminals, so the only way to manually add and delete intelligent collection terminals on the server side is manually. information; this method requires manual memory of relevant information such as the address of each intelligent collection terminal. When the number of terminals is large, it is easy to make mistakes, and it is also impossible to perform batch entry and configuration, which is inefficient; at the same time, because the terminal information comes from manual methods, Therefore, this method cannot realize a mechanism for automatic computer processing.
