The embodiment of the invention provides an equipment command calling method and system. The method comprises the steps that upper-layer application sends a command calling instruction to a command execution interface, and the command execution interface determines a name of an equipment command needing to be called and a type name of execution equipment corresponding to the equipment command according to the command calling instruction, searches and executes metadata in configuration files according to the type name and the name of the equipment command, takes out a binding equipment command processing program, executes the binding equipment command processing program and sends the equipment command to the execution equipment. The upper-layer application calls the unified command execution interface to complete calling of equipment commands of various equipment, a metadata idea is adopted, command processing programs of the various equipment are searched and executed through the metadata, when new equipment is added in a system, new equipment command calling program codes do not need to be edited, original system program codes do not need to be modified, the workload is smaller, the extendibility is higher, and the maintainability and the reliability are better.
Description
technical field [0001] The invention relates to a device command calling method and system. Background technique [0002] With the increase of equipment types, in various application systems, such as monitoring application systems, it is often necessary to perform unified real-time monitoring and control on a large number of different types of equipment, and developers need to develop a monitoring system according to specific equipment. Although there are many similarities and similarities in different monitoring systems, the command formats of different devices are various, and the command execution methods are also different. Each type of device has its corresponding device command. When sending device commands, the upper layer application needs to directly call different device commands through different command calling methods. Therefore, when a new device is added to the system, it is necessary to write a new device command processing program code and a device command ...
