In the following description, the same reference numerals are used for the same parts.

First Reference Example First, an interlocking device for a railway signal security system of a first reference example according to the present invention will be described with reference to FIGS.

  The interlocking device 100 of the railway signal security system shown in FIG. 1 includes control instruction information input from a control device 1 such as a terminal device or a CTC device, and a site input from a field device 2 such as a track circuit, a switch or a traffic light. This is for controlling a plurality of field devices 2 in association with each other based on the device status information, and includes interlocking logic operation means 10 and interlocking logic operation control output verification means 20.

  The interlocking logic operation means 10 performs an operation process on the control instruction information input from the control device 1, the field device state information input from the field device 2, and its own internal information based on a predetermined link logic, and the calculation result is Are output to the field device 2 and the interlocked logic operation control output verifying means 20.

  When the interlocking logic operation control output verification means 20 receives the internal information of the interlocking logic operation means 10 in addition to the control instruction information, the field device status information, and the interlocking logic operation control output, the interlocking logic operation control output, the verification control output, Are compared to verify whether there is an abnormality in the interlocking logic operation control output.

  At this time, the interlocking logic operation control output verification means 20 has a verification control output storage unit 21, a verification control output processing unit 22, and a control output verification unit 23 as shown in FIG.

  The verification control output storage unit 21 uses, as the verification control output, the interlocking logic operation control output to be output by the interlocking logic operation means 10 based on the control instruction information, the field device state information, and the internal information of the interlocking logic operation means 10. The control instruction information, the field device state information, and the internal information of the interlocking logic operation means 10 are stored in correspondence with all combinations.

  When the control instruction information, the field device state information, and the internal information of the interlocking logic operation means 10 are input, the verification control output processing unit 22 selects a verification control output corresponding to the combination of these and outputs a verification control output storage unit 21 and output to the control output verification unit 23.

The control output verifying unit 23 compares the interlocking logic operation control output input from the interlocking logic operation unit 10 with the verification control output input from the verification control output processing unit 22, thereby outputting the interlocking logic operation unit 10. Verify whether there is an abnormality in the interlocking logic operation control output.
When the deviation of the interlocking logic operation control output with respect to the verification control output exceeds the reference value, it is determined that the interlocking logic operation control output is abnormal.

  The verification result by the control output verification unit 23 includes the input control instruction information, the on-site equipment state information, the internal information of the interlocking logic operation means 10, the interlocking logic operation control output output by the interlocking logic operation means 10, and the verification used for the verification.

At times, the interlocking logic operation control output verification means 20 performs verification in real time step by step.
At this time, in the verification control output storage unit 21, in addition to the control instruction information input from the control device 1 and the field device state information input from the field device 2, any internal information of the interlocking logic operation means 10 is considered. A control output for verification corresponding to the operating condition is stored.
Thereby, according to the interlocking device 100 of the first reference example, it is possible to reliably verify all the operations under extremely diverse operating conditions.
Further, since the control output verification means 20 verifies the presence or absence of the interlock logic operation control output, the operation of the interlock device 100 can be reliably verified without being influenced by the knowledge and skill of the verifier. .

The interlocking logic operation control output processing unit 32 extracts the interlocking logic operation control output corresponding to the input control instruction information and the field device state information from the interlocking logic operation control output storage unit 31 and outputs it to the control output processing unit 33.
That is, the control output processing unit 33 outputs the interlocking logic operation control output previously output by the interlocking logic operation means 10 in response to the control instruction information and the field device state information identical to the control instruction information and the field device state information input this time. Is output.
The interlocking logic operation control output processing unit 32 stores the interlocking logic operation output input from the interlocking logic operation means 10 in the interlocking logic operation control output storage unit 31 in association with the control instruction information and the field device state information. It also plays a role.

The control output processing unit 33 receives the interlock logic operation control output from the interlock logic operation means 10 and the verification control output and the control output verification result from the interlock logic operation control output verification means 20.
When a control output verification result indicating that the interlock logic operation control output output by the interlock logic operation means 10 is abnormal is input from the interlock logic operation control output verification means 20, the control output processing unit 33 Instead of the interlocking logic operation control output output by the logic operation means 10, the interlocking logic operation means 10 outputs the previous time corresponding to the control instruction information and the field equipment state information identical to the control instruction information and the field equipment state information input this time. The linked logic operation control output is output to the field device 2.

  That is, according to the interlocking device 500 of the fifth reference example, when an abnormality is recognized in the interlocking logic operation control output that the interlocking logic operation means 10 outputs this time, this abnormal interlocking logic operation control output is output to the field device 2. Can be prevented, and since the normal interlocking logic operation control output previously output by the interlocking logic operation means 10 can be output to the field device 2, the field device 2 can be operated normally. .
