[0042] Principle of turnout machine fault simulation system:

[0043] The switch machine fault simulation system is a self-constructed switch machine training fault simulation system that aims to protect on-site training equipment and facilities, improve employees' fault handling capabilities, and improve the efficiency of fault drills. The switch machine fault simulation system connects the simulated operating panel and buttons with the actual circuit, presets the fault point in the equipment in advance, and installs a button switch at the fault point. It is designed through wiring and welding, and the simulated panel is connected to the actual equipment circuit through cables. The purpose of designing the fault is achieved by turning on and off the button, and the purpose of restoring the fault is achieved by closing the switch. The wiring is not moved, and the contact point is not sealed. The fault button of the simulated panel corresponds to the actual equipment position on site one by one to ensure the accuracy of the fault point.

[0044] How to use the turnout machine fault simulation system:

[0045] 1. Before use, check whether the buttons ① to ㊷ set in the turnout machine fault simulation system are in normal working condition, whether the wiring is neat, not broken, and well fixed.

[0046] 2. Operate the turnout on the HMI (host computer operation interface) to check whether the turnout positioning and reverse position starting circuits, and the positioning and reverse position indication circuits are normal.

[0047] 3. Press buttons ① to ㊷ to set the open circuit fault and confirm that the turnout fault phenomenon is displayed correctly on the HMI (host computer operation interface).

[0048] 4. During the fault finding process, confirm that the on-site fault point corresponds to the fault point set by buttons ① to ㊷ of the turnout machine fault simulation system.

[0049] 5. After the fault finding is completed, press buttons ① to ㊷ to restore the corresponding fault point and confirm that the turnout circuit has returned to normal.

[0050] 6. After use, confirm that buttons ① to ㊷ of the turnout machine fault simulation system are in normal working condition, and confirm that the turnout machine equipment has resumed normal use.

[0051] Effects of the utility model:

[0052] Due to the complexity of the working principle of the turnout circuit, when dealing with turnout faults, it requires close cooperation of dedicated personnel to set the fault point. In the past, at least two trainers were required to participate in turnout fault training. The turnout switch machine fault simulation system shortens the examination time for one person to 70% of the original time, and the range and number of faults that can be set on site have been increased by more than 80%, effectively improving the training efficiency.

[0053] The fault simulation system of the turnout machine can prevent adverse effects on the equipment caused by frequent fault settings, so as to ensure the stability of equipment performance and provide conditions for the normal operation of the equipment.
