Embodiment 1

[0019] A multi-channel synchronous working method based on multiple network modes, such as figure 1 shown, including the following steps:

[0020] Step 1: Data lane splitting: The data sender obtains the weight value of a channel according to the signal strength of the current network, the delay value of channel data arrival per unit time, and the bit error rate of channel data transmission per unit time, which is Each piece of data is assigned a channel, so that channels with high weights can transmit more data or more important data, and channels with low weights can transmit less data or less important data;

[0021] Step 2: Data packetization: The data to be sent is packetized according to the weight value of the channel, the data type, and the length of the data. It is a key frame, and it is sent according to the data of 4 channels first. If there are less than 4 channels, Take the maximum value of the available channel. If it is not a key frame, the channel with high we...

Embodiment 2

[0029] In view of the shortcomings of the traditional single-channel transmission mode, such as low bandwidth, poor reliability, and small coverage area of ​​a single network, in order to effectively achieve high transmission performance, multi-channel, and multi-network synchronous use has become an inevitable trend. Therefore, our foothold lies in Research on the multi-channel synchronous transmission technology of multi-network, including channel allocation mechanism, data sub-packet strategy, data receiving and processing strategy and feedback mechanism of receiving status, such as figure 1 Shown in the following steps:

[0030] 1. Channel allocation mechanism

[0031] A channel is a channel in the process of data transmission. Channel allocation is to assign a channel to each piece of data and send it out in a certain order. The purpose of channel allocation is to allow the data to be sent in an orderly manner, so that the receiving end can receive it in an orderly manne...

Abstract

The invention relates to a signal synchronous working method, and discloses a multi-channel synchronous working method based on multiple network modes. The method comprises the steps of: channeling data, packaging the data, identifying the data, receiving the data and feeding back the data. The technical scheme of the method solves the defects of low bandwidth, bad reliability and less signal network coverage area, and the like, in a traditional single channel transmission mode, achieves the transmission performance with high order digit, and effectively coordinates the distribution mechanism of the information channels, the subpackage strategy of the data, the receiving strategy of the data and the feedback mechanism of the receiving status.

Description

technical field [0001] The invention relates to a synchronous working method, in particular to a multi-channel synchronous working method based on multiple network modes. Background technique [0002] With the continuous development and construction of my country's market economy, the current traditional single-channel transmission mode has disadvantages such as low bandwidth, poor reliability, and small single network coverage area, which cannot achieve high transmission performance. However, the synchronous use of multi-channel and multi-network It has become an inevitable trend. For example, the law enforcement equipment of public security officers cannot meet the needs of efficient law enforcement by relying on the existing bulky vehicle monitoring system or simple hand-held video cameras, cameras or tape recorders. If an emergency occurs when the police car cannot enter If the location is too small, the on-board system will be useless, and the hand-held recorder alone can...
