Problems solved by technology

[0007] Due to the adoption of the above scheme, multiple control messages are encapsulated in one communication message, thereby reducing the relative proportion of the communication frame header in the communication message, improving the carrying efficiency of the communication message, and solving the problem in the monitoring network. The problem of low transmission efficiency of control packets between multiple devices

Embodiment Construction

[0011] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0012] See figure 2 , as can be seen from the figure, in the improved communication control layer protocol, multiple control messages are encapsulated in one communication message, thereby reducing the relative proportion of the communication frame header in the communication message and improving the communication message carrying efficiency.

[0013] In order to encapsulate multiple control packets into one communication packet, the following communication control protocol is designed, its structure is as follows image 3 shown.

[0014] Among them, the "bottom protocol frame header" field is different due to different bottom communication protocols, such as Ethernet protocol frame header, TCP / IP protocol frame header and so on.

[0015] The "number of control packets" field indicates the total number of control packets ...

Abstract

The invention discloses a transmission method of control message in monitoring system, its character: it includes the steps: it packages the control message produced by the node into communication message, and the control message is added in the communication frame head to compose the communication message packaged with multiple control messages; it transfers the communication message to the communication control layer of the reciprocal node; the control layer receives and analyzes the communication message to recover the control message, and transfers the control message to application control layer.

Description

Technical field: [0001] The invention relates to a method for transmitting control messages in a monitoring system. Background technique: [0002] In a typical monitoring system network, the communication structure between two communication devices is as follows: figure 1 shown. Each node (console or monitored device) in the system has two parts: the application control layer and the communication control layer. Among them, the application control layer realizes the functions of the application level, such as user interface, sending and receiving of monitoring commands and so on. The application control layers between different nodes carry out information exchange and coordination through control messages, so as to realize control and being controlled. [0003] Control messages between different nodes cannot be transmitted directly on the application control layer, but must pass through the communication control layer. The communication control layer is responsible for r...
