Embodiment Construction

[0039] Such as image 3 Shown, include in the data packet of the present invention: be used for forming the additional information (Preamble) domain of the data packet beginning portion of hint data packet beginning; Synchronization control (Sync Control) domain; Be used for including the length (size) The MAC layer control part; the transmitted data; the error detection part (CRC) for detecting the error when the data packet is transmitted. The following will take the data packet generated in the master device (MD) 10 and transmitted to the slave device (SD) 11 as an example for illustration.

[0040] More specifically, the additional information field at the start of the packet is used to indicate the start of a packet to the slave device (SD) 11, and the additional information field has a size of 3 bytes. Wherein, when the value contained in the above-mentioned additional information field is '0xAAAAAA' (wherein, '0x' represents a hexadecimal number), the slave device (SD)...

Abstract

The present invention is a data packet receiving method, comprising: first judging step of judging whether a first data expresses beginning of a data packet after receiving the first data; first receiving step of additionally receiving a second data according to the judged result of the first judging step; second receiving step of additionally receiving a third data according to values of special bits of the second data; second judging step of reading an error detection data from the third data and judging whether transmission of the second and third data is exact or not; processing step of processing the second and third data according to the judged result of the second judging step. And the data packet receiving method also comprises: reading step of reading values of remaining bits of the second data; second processing step of transmitting or neglecting the second and third data according to the read values. And it can improve receiving accuracy of data in data packet and raise data packet receiving efficiency.

Description

current technology [0001] The invention relates to a data packet receiving method. Background technique [0002] A home network refers to a local area network that connects multiple digital home appliances to each other in order to enjoy comfortable, safe, and economical life services indoors and outdoors at any time. With the development of digital signal processing technology, refrigerators or washing machines, which were previously called white goods, have gradually been digitized. With the integration of home appliance application system technology and high-speed multimedia communication technology into digital home appliances, and the continuous introduction of new forms of information home appliances, The above-mentioned home network technology is further developed. [0003] like figure 1 As shown, the structure of the existing home network data packet includes: a bit synchronization field (bit sync) for indicating the beginning of the data packet; a word synchroniz...
