<p>PURPOSE:To improve the reliability of transmitting data by composing to connect an operation board with a vehicle transmission line of a through line in a composed vehicle. CONSTITUTION:An operation board 6 is composed to be connected through a ground transmission line 4A with a vehicle transmission line 4 fed through composed vehicles. Information of nonvolatile memory is transmitted and collected from each terminal station by applying information transmission request command of the memories 24, 34, N4 to terminal stations 22, 32, N2 at connecting time to the line 4. Thus, a ground transmitting controller, a modem circuit and a transmitting control program can be eliminated in the central station.</p> |
