<p>PURPOSE:To eliminate the wasteful space which is occupied by a central device in an operation chamber by coupling a terminal unit, the central device and a display unit via a common transmission line. CONSTITUTION:A central device 9 requests as a master station collection of information through a transmission line 11 to terminal units 7A-7C of respective trains by the operator's operation or interrupt. The respective terminal units 7A-7C collect and input information of a contact which represent the operating states or defect state of respective train equipments 6A-6C and transmit the information through the line 11 when an identification number from the central device 9 coincides. The central device 9 outputs the collected information of the terminal units 7A-7C of the trains 1-3 to an external device. Display units 10A, 10C receive the information from the central device 9, select to input or dispose, sort and integrate the information, edit, process and display it. In this manner, the number of the central devices can be reduced.</p> |
