Embodiment Construction

[0093] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the implementation of the pre-redundant architecture of the acquisition system that facilitates protocol expansion according to the present invention is only an example, but the present invention is not limited to this specific implementation.

[0094] see figure 1 , a pre-redundancy architecture diagram of an acquisition system that facilitates protocol expansion in the present invention, mainly including a host system, a redundant pre-device (dual machine), channels, and equipment. The host system runs a host management module, which is used to start the access service process of the real-time acquisition system, actively set the main front-end operation, communicate with the front-end management module process on the main front-end machine, and realize the redundant management of the front-end s...

Abstract

The invention discloses the prepositive redundant architecture of an acquisition system convenient for protocol extension, which is used for realizing the redundant function of a prepositive computer collecting data in a control system, and comprises a host management module, a prepositive management module, and a state management module. The invention also discloses a realizing method for the prepositive redundant architecture of the data acquisition system. The prepositive redundant architecture of the data acquisition system formed by adopting the technical proposal of the invention can lead the data acquisition system to be provided with good expansibility when different types of new acquisition devices are added to the data acquisition system. The system has clear structure, thus effectively realizing the exchange of main and standby route double prepositive computers, when an acquisition protocol is newly added, and independent development can be carried out without influencing the function of other modules and other acquisition protocols in the prepositive redundant architecture and the systematical normal use of data acquisition.

Description

technical field [0001] The invention relates to a data collection and monitoring system in the field of computer control, in particular to a pre-redundant architecture and method of a collection system that is convenient for protocol expansion. Background technique [0002] In the data acquisition and monitoring system, the general data acquisition function is realized by the front-end computer. For the stability of the front-end computer and other considerations, the main and backup dual front-ends are often used to guarantee the acquisition function. The advantage of the working mode of the main and standby dual front-end processors is that the main front-end processor needs to stop working for some reason, or in case of failure, the backup front-end processor can be automatically upgraded to the main front-end processor to complete data collection in the system, etc. Function. [0003] The existing active-standby dual front-end redundant architecture generally adopts two...
