<P>PROBLEM TO BE SOLVED: To provide a communication method that improves the integrity of transmission information and inhibits an increase in transmission data. <P>SOLUTION: A communication method transmits a detection signal including a valve ID, which is a fixed data string, and detection information, which is a variable data string and desired to increase redundancy, performs error detection of the received detection signal, and adopts the received data of the received detection signal when there is no error. The communication method creates third data corresponding one-to-one to the detection information to make the detection information redundant according to a predetermined rule, calculates computation data by performing exclusive-OR of the valve ID, detection information, and the third data, transmits a detection signal including the computation data, receives the detection signal and restores the detection information and the third data from the computation data by performing exclusive-OR of a pre-stored valve ID and the computation data, and adopts the reception data of the received detection signal determining there is no error when the detection information and the third data accord. <P>COPYRIGHT: (C)2013,JPO&INPIT |
