Abstract

PURPOSE:To offer a transmitting method and a receiving method for continuous serial data, which can reproduce exactly true data, and also, to offer a receiving method for continuous serial data, which can take word synchronization of transmitted serial data by a simple constitution. CONSTITUTION:To the head part of true data 2 to be transmitted, a code 3 of bit length determined in advance is added and it is transmitted. Also, in a receiving method for receiving transmitted continuous serial data, the serial data is converted to parallel data of bit length determined in advance. This converted parallel data is compared with this prescribed code. When the converted parallel data 3 and the prescribed code coincide with each other, reproduction is executed. In such a way, true data can be reproduced exactly. Also, word synchronization of the transmitted aerial data can be taken by a simple constitution.

However, accurate reading of the true data sent was almost impossible unless the beginning and end of each true data sent were known exactly. In addition, there is a drawback that an error is generated at the time of data reproduction due to inevitable mixing of noise in the transmission line during transmission. Therefore, a technical object of the present invention is to provide a serial data transmission method and serial data reception method capable of accurately reproducing true data. Further, another technical problem of the present invention is to provide a serial data transmitting method and a serial data receiving method capable of word synchronization of transmitted serial data with a simple configuration.

At the terminal 10, the continuous serial data received is
From the input terminal, and is sequentially converted into 8-bit parallel data 5 in the shift register 11 and then supplied to the comparator 21. The comparator 21 is set with an 8-bit code 20, which is equal to a predetermined 8-bit code added at the time of transmission. The comparator 21 compares the set 8-bit code 20 with the 8-bit parallel data 5 supplied from the shift register, and the converted 8-bit parallel data 5 and the set 8-bit code Latch clock pulse 22 when the pattern matches
Is output. 8-bit data after the latch clock pulse 22 is output, that is, 8 bits following a predetermined code 3.
