[0041] Based on the content recorded in the background art, the inventor found in the process of the invention and creation of the present invention that in order to ensure the driving safety of trains, currently, a test device needs to be temporarily built before the computer interlocking system is used, and then manual operations are carried out.

Therefore, how to improve the test work efficiency of the computer interlocking system is a technical problem that those skilled in the art need to solve urgently.

[0042] Based on this, the present application provides a test device for a computer interlocking system, which can improve the test work efficiency of the computer interlocking system.

[0044] An embodiment of the present invention provides a test device for a computer interlocking system.

In combination with Figure 1 , the test device for the computer interlocking system includes: a cabinet 1, and an industrial control computer 2, a serial port I / O controller 3, a plurality of (only one is shown in the figure for display) acquisition switches 4, and a plurality of (only one is shown in the figure for display) relays 5 located inside the cabinet 1.

[0045] Among them, each acquisition switch 4 is respectively connected in series to the transmission branch of the corresponding channel acquisition signal of the acquisition board 7 in the computer interlocking system 6 to be tested; the control ends of each acquisition switch 4 are respectively connected to the corresponding output ends of the serial port I / O controller 3; each relay 5 is connected in parallel between the positive and negative poles of the test power supply 8; the control ends of each relay 5 are respectively connected to the corresponding output interfaces of the drive board 9 in the computer interlocking system 6 to be tested; the serial port I / O controller 3, the acquisition board 7 and the drive board 9 are respectively communicatively connected to the industrial control computer 2.

[0046] The industrial control computer 2 is configured to: output an acquisition instruction to the serial port I / O controller 3 to cause the serial port I / O controller 3 to control the corresponding acquisition switch 4 to close; and determine through communication whether the acquisition board 7 has received the acquisition signal provided by the corresponding acquisition switch 4, and generate the corresponding channel detection information of the acquisition board 7; and, output a drive signal to the drive board 9 to cause the drive board 9 to control the corresponding relay 5 to pull in, and determine through communication whether the drive board 9 has controlled the corresponding relay 5 to pull in, and generate the corresponding channel detection information of the drive board 9.

[0047] Specifically, in the embodiment of the present invention, the acquisition board 7 and the drive board 9 in the computer interlocking system 6 to be tested are both located in the IO chassis of the interlocking cabinet of the computer interlocking system 6 to be tested, and the industrial control computer 2 is communicatively connected to the IO chassis of the interlocking cabinet; as Figure 2 shown Figure 2 is a schematic structural diagram of a serial port I / O controller provided by an embodiment of the present invention. The control ends of the acquisition switches 4 are respectively connected to the corresponding output ends of the serial port I / O controller 3.

[0050] Specifically, in the embodiment of the present invention, the external power supply method includes, but is not limited to, using a 220V AC power supply 11 to supply power to the test power supply 8.

When the collection power supply is normally powered, the second circuit breaker indicator light is lit.

The drive circuit breaker is connected to the positive pole of the 24V power supply combination, and the third circuit breaker indicator light is connected to the negative pole of the 24V power supply combination. When the power supply combination outputs 24V DC power, the third circuit breaker indicator light lights up.
