Abstract

The invention is suitable for the field of remote equipment control and provides a browser-based remote control method. The method comprises the following steps: a server receives an operating command which is transmitted by a browser of a client, and the operating command generates an Ajax object in Java Script; the server receives the operating command and then transmits the operating command to remote equipment; the server organizes command execution results returned by the remote equipment into an execution result object, and returns the object to the client in JSON format; and the client analyzes the returned result by means of page layout and displays the returned result. The invention implements, combines and uses the up-to-date technology in the field of web development such as Ajax and JSON, and provides a novel method for developing a real-time control system or a data monitoring system on web. The method is simple and effective, can greatly simplify the program flow, reduce server burden and network flow load, and well improve operation experience of customers and the interface display effect.

Description

technical field [0001] The invention relates to the field of remote device control, in particular to a browser-based remote control method. Background technique [0002] In the past, when developing remote equipment operation or real-time data acquisition systems, most of them used C / S (client / server) structure to develop software. C / S is a mode of programming: client plus server. The client directly establishes a network connection with the server, sends commands to the server, receives and displays the returned results. Now software development is gradually evolving to a B / S (browser / server) structure. The software system of B / S structure reduces the trouble of installing software on the client side. [0003] However, in software with B / S structure, especially asynchronous and long-term operations, it is difficult to synchronize the execution status of the server and the display interface of the client. The software system of the B / S structure is based on stateless and...
