FIG. 1 is a block diagram of a processing apparatus showing an embodiment of the present invention. 1 is a computer (personal computer),
At the center of this configuration, all the processing associated with the input of the wiring diagram, the processing for creating the interlocking logical data, and the simulation operation processing for the interlocking condition are performed. A display device (CRT) 2 displays a wiring diagram and various input conditions and interlocking conditions. A mouse 3 draws a figure such as a wiring diagram and at the same time shows the position of the figure element. Reference numeral 4 is a keyboard for instructing various graphic elements being drawn or conditions for input / output. A printer 5 prints out various computer processing results. Further, 6 is a floppy disk (FD), 7 is a hard disk, and these store the graphic data obtained by inputting the wiring diagram.

The processing apparatus configured as described above inputs a connection diagram, creates interlocking logic data, simulates the interlocking condition, and outputs the result for verifying the correctness of the interlocking logic data. The procedure for doing so will be described with reference to the flowchart in FIG.

First, the operator uses the mouse 3 to
By repeatedly selecting and instructing graphic pixels in the wiring diagram input / editing program stored in the computer 1 in advance, a wiring diagram including circuit groups such as relays, contacts, and switches is drawn on the CRT 2 to The figure to be stored is stored in the floppy disk 6 (or hard disk 7). At this time, all wiring terminals such as relays as graphic pixels are given a series of names, and if there is wiring between terminals such as relays, the terminals will be combined with the above-mentioned graphic pixel information as necessary. The wiring status is stored using the name.

Next, using the graphic data and wiring data obtained as described above, each circuit component and terminal area are allocated on the file, and the address on the floppy disk 6 of the connection destination terminal is written in the terminal area. , The circuit wiring state represented by the circuit diagram is faithfully constructed on the floppy disk 6. The logical expression corresponding to the input wiring diagram can be obtained by checking all the buses (wiring paths) that reach the power supply necessary for terminal determination in the floppy disk 6 for the operation of each relay, save. In this way, the interlocking logic data used for the interlocking condition of the railway signal interlocking device can be easily created from the wiring diagram.

Next, in order to verify the correctness of the interlocking logical data consisting of the logical expressions corresponding to the input wiring diagram, the operator sets the interlocking condition based on the interlocking diagram which is the basis of the wiring diagram on the computer 1. Simulated interlocking control panel and traffic lights displayed on the CRT2 to verify the interlocking logic data created and the interlocking conditions (also referred to as interlocking inspection, including correction confirmation) This is performed by checking the results of the interlocking simulation operations that are sequentially displayed on the field equipment, and the correctness of the logic of the logical expression is checked.

Further, as auxiliary means for checking the correctness of the logic of the above logical expression, the wiring data stored in the hard disk 7 of the computer 1 is used, and the current flows through all the wirings according to the given interlocking condition. There is also a method to check the operation of each relay by checking if the current is actually supplied to each relay.

The operation result according to the interlocking condition of the interlocking logical data is displayed on the simulated interlocking control panel on the CRT 2 and the simulated field device, or is represented by the operation and recovery state of each relay forming the wiring diagram, and the printer 5 To print out.

Therefore, the operator can easily judge the correctness of the interlocking logic data by checking the display of the result of handling the signal lever or the like displayed on the simulated interlocking control panel on the CRT 2 and it must be suitable. For example, the correction and addition of the connection diagram are input to the computer 1 and repeated to obtain the interlocking logic data that can be used for the interlocking condition of the target interlocking device. By repeating the procedure as described above, the intended interlocking condition is completed.
