<p><P>PROBLEM TO BE SOLVED: To provide a technology capable of decreasing the deterioration of a traffic flow even if interlocking abnormality is generated in a signal system equipped with an interlocking master unit and an interlocking slave unit. <P>SOLUTION: An interlocking master unit 101 records cycle information produced when the cycle of the interlocking master unit 101 is finished, in its master unit side history log, and transmits the cycle information to an interlocking slave unit 102. The interlocking slave unit 102 stores the cycle information transmitted from the interlocking master unit 101 in a slave unit side history log of a slave unit read-changing portion 114. The slave unit side history log can stores the cycle information, for example, in the maximum duration of one week, and overwrites the cycle information after the elapse of one week or more. The interlocking slave unit 102 reads out data of the same date and the same time from the history log of the slave unit read-changing portion 114 when interlocking abnormality is detected, and applies the data as a pattern for self-traveling. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
