Problems solved by technology
However, the shortcomings of this method are reflected in two aspects. On the one hand, when the communication channel is less interfered, the error correction code is fixed, and the data transmission rate cannot be adjusted; In the case of a large value, the error correction capability cannot be adjusted, resulting in a reduction in transmission reliability

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, so as to specifically illustrate the technical solution of the present invention. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0021] Such as figure 1 As shown, an adaptive method for error correction capability based on a power line carrier communication system of the present invention specifically includes the following steps:
[0022] Step 1: The master device initializes the parameters of each slave device, including the communication protocol setting between the master device and the slave device, the initial speed level and error correction level of each slave device, and initializes the communication success rate record table of each slave device ;
[0023] Step 2: The master device counts the communication success...

The invention discloses an error correction capability self-adaption method based on a power line carrier communication system, and aims to further improve the communication efficiency among one master device and multiple slave devices. On the basis that attenuation difference exists in power line carrier communication channels with one master device and multiple slave devices and communication channels can change, the technical method capable of achieving automatic distribution of error correction levels between the master equipment and the slave equipment and rapidly responding to channel changes between the master device and the slave devices is achieved. According to the method, the communication efficiency among one master device and multiple slave devices can be further improved. The automatic distribution of the transmission rate and the error correction level of the slave equipment is realized; and on the other hand, the change of the communication success rate corresponding to different transmission rates and error correction levels of each slave node can be recorded, and the appropriate communication rate and error correction level can be switched to according to the communication condition of each slave node.
Description
technical field [0001] The invention relates to the field of power line carrier communication, in particular to an error correction capability adaptive method based on a power line carrier communication system. Background technique [0002] With the continuous development of power line carrier communication technology and the rapid development of related technologies, the requirements for the efficiency and reliability of data transmission are becoming more and more stringent. In order to improve the reliability of data transmission, the data will be encoded at the sending end and added correction For error codes, the data receiving end performs corresponding decoding operations to recover the error codes caused during data transmission. [0003] At present, the existing technical solutions are fixed error correction capabilities and error correction codes at the sending end and the receiving end. This technical solution is widely applicable to the situation where the interf...
