[0151] The present invention provides a switch machine simulation device. The switch machine is an important railway signal infrastructure equipment, which is mainly used to convert the switch position, change the direction of the switch opening, lock the switch passage, and reflect the switch position, etc. As mentioned above, the core component of the switch machine is the switch plate, which is the core component that directly performs the above functions. In this regard, the present invention proposes a switch machine simulation device for verifying or testing the switch plate.

[0152] like Figure 1 As shown, this embodiment provides a switch machine simulation device (intelligent switch machine simulation device) 10, including:

[0153] The host computer 100 , and an AC switch module 101 , a DC switch module 102 , an interference injection module 103 and an interface module 104 that respectively exchange information with the host computer 100 .

[0154] The host computer 100 is configured to control and adjust each module according to user instructions and display the operation information of the device and the switch board in real time.

[0155] The AC switch module 101 and the DC switch module 102 are respectively configured to execute the action process and action scene of the simulated AC switch and DC switch according to the received user instructions;

[0156] The interference injection module 103 is configured to output an interference signal according to a received user instruction and to feed back interference information parameters to the host computer 100;

[0157] The interface module 104 is configured to perform switching of the interfaces of the AC switch machine and the DC switch machine and to inject the interference signal.

[0158] The interface module is respectively connected to the power supply module, the host computer, the AC switch machine module, the DC switch machine module, the interference injection module and the switch board, receives current, and executes AC switch interface operation / DC switch interface operation / interference interface operation according to the AC switch command / DC switch command / interference command; the host computer displays the operation information of the device and the switch board under the AC switch interface operation / DC switch interface operation / interference interface operation.

[0159] Specifically, the user instructions include but are not limited to: setting information of the AC switch module, DC switch module, interference injection module, and interface module; application scenario information of the AC switch module, DC switch module, interference injection module, and interface module devices; interference information parameter information of the interference injection module, etc.

[0160] The operation information includes but is not limited to: real-time parameter information of the AC switch module, the DC switch module, the interference injection module, the interface module equipment, current information, and operation parameter information of the switch board.

[0161] Among them, the final functions of the AC switch machine module and the DC switch machine module are the same, both of which output a message for testing the operation of the switch board to the interface module; however, the two modules are mutually exclusive during operation, that is, only one of them can operate at the same time. Specifically, the AC switch machine module and the DC switch machine module output four types of information for testing the operation of the switch board, simulating switch positioning, simulating switch positioning to reverse position operation, simulating switch reverse position, and simulating reverse position to positioning operation; positioning and reverse position are the two basic states of the switch machine. Positioning refers to the state of normal operation of the switch machine, while reverse position refers to the state of the switch machine when it is special or needs to change the driving direction. The mutual conversion of switch positioning to reverse position ensures that the train can travel according to the predetermined route.

[0162] It can be seen that the switch machine simulation device provided in this embodiment can simulate the switch machine action circuit, indicate various abnormalities of the circuit, and verify the accuracy of the switch board alarm. According to user needs, the indication and control relay closing timing can be flexibly set to simulate various action durations of the switch machine, and verify whether the switch loss indication threshold settings in various software are reasonable. The action current value can be flexibly adjusted to verify the sampling accuracy of the switch board; simulate the diode leakage level to verify the impact of different levels of leakage on the sampling results of the switch board; set various fault simulation formulas, simulate various fault curves, and verify the sampling ability of the abnormal curve of the switch board; complete interference injection according to user needs to verify the anti-interference ability of the switch board.

[0163] Please continue to refer to Figure 1 As shown, the switch machine simulation device 10 also includes: a power supply module 105. Generally speaking, there will be a working power supply port and an interference power supply interface, wherein the working power supply interface is connected to the host computer, the AC switch machine module, the DC switch machine module and the interference injection module to provide working power for them. For the interference injection module, an interference power supply interface is designed, so that the generation of interference commands can be realized without affecting the normal operation of the host computer, the AC switch machine module, the DC switch machine module and the interference injection module (because they also need to obtain operation information, etc. by the host computer, so they cannot be mixed, otherwise it may cause confusion in parameter capture).
