<p>PURPOSE:To surely attain a data communication while traveling by performing a processing corresponding to reception data when the reception data of each carrier are the same from the carrier in use. CONSTITUTION:A CPU 21 transmits an RS signal to a slave station 3 prior to the transmission of transmission data from a central processing unit 1 to the slave station 3 and transmits the data according to the response of the slave station 3. Also, when a carrier detecting signal is inputted from the slave device 3, the CPU 21 allows a master station 2 to store the reception data from the slave station 3 at this time. Moreover, the CPU 21 adds the identification data of a carrier 5 to the front of control data, transmits the transmission data to the slave station 3, extracts the identification data from the reception data from the slave station 3 and identifies one of the carriers 5 from the identification data. On the other hand, when the extracted identification data are matched with the stored identification data, the carrier 5 operates a traveling start, turning right, turning left and stoppage, etc., corresponding to the reception data.</p> |
