Problems solved by technology
Since most of the communications in my country's rural power systems adopt the "CDT (Cyclic Telecontrol Protocol)" communication protocol formulated by the Ministry of Electric Power in the early days, and the feature of this protocol is to actively send data back and forth in the communication channel, resulting in a large amount of communication data traffic. , the transmission efficiency is low, and it needs to occupy a large amount of communication bandwidth, resulting in a waste of communication resources
In the communication of other similar systems (such as meteorological monitoring system, energy (coal, oil, natural gas) production and transportation system, water conservancy dispatching system, hydrological monitoring system, etc.) Large data traffic, low transmission efficiency, and waste of communication bandwidth

Embodiment Construction
[0023] The main idea of the present invention is to perform optimization processing on the repeatedly transmitted information at the entrance of the communication channel, and then transmit it through the communication channel, wherein the optimization processing includes filtering out redundant information. The present invention is applicable to all communication systems that repeatedly transmit information in communication channels, such as communication systems of power grid automation systems, meteorological monitoring systems, energy production and transmission systems, water conservancy dispatching systems, and hydrological monitoring systems.
[0024] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In this embodiment, the power grid automation communication system is taken as an example to illustrate the information transmission method of the present inventi...

The invention relates to an information transmission method applied to a communication system used for repeatedly transmitting information in a communication channel. The method comprises the following steps of: carrying out optimization treatment on repeatedly transmitted information at the entrance end of the communication channel and then transmitting the information through the communication channel, wherein the step of optimization treatment comprises a process of filtering out redundant information. The information transmission method can effectively reduce the redundant data, save the communication channel resources and improve the transmission efficiency.
Description
technical field [0001] The present invention relates to the communication field, in particular to an information transmission method. Background technique [0002] At present, my country's rural power grid dispatching adopts the mode of substation in the general control room, that is, the city / county-level power dispatching department monitors and remotely controls the operation of rural substations located in the power supply area in real time through the general control room, and the RTU of the remote substation ( Remote Terminal Unit, remote terminal control system) uploads monitoring data to its superior dispatching master control room, and the master control room issues control instructions to the substation. Since most of the communications in my country's rural power systems adopt the "CDT (Cyclic Telecontrol Protocol)" communication protocol formulated by the Ministry of Electric Power in the early days, and the feature of this protocol is to actively send data back a...
