<P>PROBLEM TO BE SOLVED: To solve the problem that when opening/closing control of a railroad crossing is performed from a vehicle station radio device, condition confirmation of the railroad crossing is performed depending on only visual observation of an operator, recording of opening/closing control of the crossing does not remain after work and there is no method for checking whether there is a failure to open the crossing after work. <P>SOLUTION: The vehicle station radio device includes an operation section receiving opening/closing operation command for closing or opening the crossing to a crossing opening/closing device, a display section displaying input information from the operation section, a transmission section transmitting an opening/closing request signal including an opening/closing operation command of the crossing and an identifier of the crossing to be an opening/closing operation object to a ground station radio device, a recording section recording a content of the opening/closing operation command and the identifier of the crossing included in the transmitted opening/closing request signal and a control section making the display section display that both closing and opening are not recorded when both closing and opening as the opening/closing operation command to the crossing opening/closing device of the crossing represented by the same identifier are not recorded in the recording section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
