Data interaction method, plug-in manager and computer readable storage medium

Abstract

The invention discloses a data interaction method, a plug-in manager and a computer readable storage medium. The method comprises the steps that the plug-in manager loads plug-ins and establishes a plug-in queue, and when the plug-ins are loaded, each plug-in calls a message registration interface provided by the plug-in manager, and registers a message identification ID needing to be responded byeach plug-in in the plug-in queue; The plug-in manager receives the message, selects a plug-in response message in which the message ID registered in the plug-in queue contains the message ID in themessage. When the plug-in is loaded, a message ID which needs to be responded by each plug-in is registered; Upon responding to a message, a plug-in which needs to respond to the message is selected according to the message ID; Different plug-ins carry out data exchange through a universal flexible message mechanism according to the requirements of service processing, different software functionscan be deployed in different types of monitoring workstations according to the requirements of users, differentiated flexible deployment of the software functions of the monitoring workstations is achieved, and the implementation and maintenance difficulty of the system is reduced.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the technical field of computer software design, and particularly relate to a data interaction method, a plug-in manager and a computer-readable storage medium. Background technique [0002] There are many automation systems in the field of rail transit, which are used to realize the monitoring and control functions of on-site equipment. Typical rail transit automation systems include automatic train supervision system (Automatic Train Supervision, ATS), integrated supervisory and control system (Integrated Supervisory and Control System) , ISCS), power monitoring system (Power Supervisory Control And Data Acquisition System, PSCADA), environment and equipment monitoring system (Building Automatic System, BAS), etc. The system structure of these automation systems is divided into two parts: one part is the monitoring workstation that provides the human-machine interface, and the othe...

Problems solved by technology

[0004] The design method of the existing system monitoring workstation software is to put all the functions of the software into one module. The disadvantages of this design method are reflected in the following aspects: the efficiency of software development is low, different developers are responsible for the development of the same module, and the code is difficult management, it is easy to cause code conflicts; software reliability is low, and all functions of the software will be unavailable when a module fails; May affect other core functions; software flexibility is low, and different software functions cannot be deployed according to different types of monitoring workstations
