[0002] At present, the application of railway signal and interlocking control equipment is relatively complex, and it is even more difficult to conduct training in actual application. Some equipment that replicates the site can be used for simple training, but the training is inconvenient, and many faults and the principles of their composition cannot be simulated, drilled, or explained. With the development of information technology, the construction of a virtual simulation training base for vocational education is not only an urgent need to reform traditional teaching and education methods and promote innovation in talent training models, but also an important measure to strengthen the educational and teaching activities that integrate teaching, learning, and training, and effectively make up for the special difficulties of vocational education training such as being invisible, inaccessible, high cost, and high danger. Most solutions on the market only realize the interlocking control of signal equipment based on hardware and interlocking software control. The hardware simulation generally simulates the working status of the equipment through hardware simulation, and actively sets the line on and off to simulate the actual fault. The software mainly simulates the external performance of the equipment, and simulates the fault of the actual equipment through preset typical fault scenarios to achieve the purpose of learning for relevant personnel.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0029] like Figure 1 As shown, this embodiment provides a rail control equipment fault simulation training system, the system adopts an overall interlocking design, and the system includes:

[0030] A virtual 3D simulation module, the virtual 3D simulation module includes a virtual 3D simulation software 10 and a display screen 20, the virtual 3D simulation software 10 is connected to a local database via an interface;

[0031] A device simulation module, the device simulation module includes an electrical circuit simulation software 30, an electrical circuit 40 and a simulation signal device 50, the electrical circuit simulation software 30 communicates with the virtual 3D simulation software 10;

[0032] Interlocking software 60, the interlocking software 60 is used to drive the display screen 20 to display a virtual image through the virtual 3D simulation software 10, and to drive the electrical circuit 40 through the electrical circuit simulation software 30 to control the operation of the simulation signal device 50;

[0033] The interlocking software 60 is also used to control the device state change in the virtual 3D simulation software 10 by driving the relay state to simulate the relay terminal state change caused by the operation of the electrical circuit 40;

[0034] The interactive device 70 communicates with the virtual 3D simulation software 10 and is used to realize the interaction between people and scenes.

[0035] For example, Figure 2 As shown, the input DC 24V voltage can be converted into the DC 3.3V voltage required by the track control equipment fault simulation training system through the K78 chip.

[0036] Optionally, the virtual 3D simulation software 10 uses the scene model reconstruction technology of the Unity engine to simulate the construction of signal equipment and real scenes in a virtual environment, and then associates the electrical circuit of the simulated signal equipment 50 to drive the state change of the simulated signal equipment 50. The 3D virtual scene reconstruction technology saves the required equipment site and equipment installation and removal costs. The virtual control device of the virtual scene can also control the teaching equipment through the interlocking software 60, flexibly supplement the hardware deficiencies, and realize the working principle of the signal equipment hardware through software cooperation. During use, it only needs to enter the scene through the computer software, and it can be restored at any time afterwards, which greatly improves efficiency. The interlocking software 60 collects the circuit information in the virtual scene through the acquisition system, so that the driving module drives the device hardware to change its state.

[0037] Furthermore, the interlocking software 60 can also drive the state of the electrical circuit 40 through the electrical circuit simulation software 30 to have an open circuit fault, a short circuit fault, a ground fault, and a mixed line fault. The states of the electrical circuit represent different simulated track control equipment fault states, and the electrical circuit states are controlled by relays to change the device state in the virtual 3D simulation software 10:

[0038] Specifically, (1) execute the open circuit fault by operating the electrical circuit software 30 to select 1 fault point and click to send the fault, and send 1 relay closing instruction to the specified IP fault box through the host computer, 1 relay is closed, NC and COM are connected to the function line, and the relay is closed to indicate an open circuit fault;

[0039] (2) Execute the short-circuit fault by operating the electrical circuit simulation software 30 to select a fault point and click to send the fault. The upper computer sends a relay closing instruction to the specified IP fault box, and the relay is closed. NO and COM are connected to the function line. After the relay is closed, it is a short-circuit fault;

[0040] (3) Execute the ground fault by operating the electrical circuit simulation software 30 to select 1 fault point and click to send the fault. The host computer sends a 1-way relay closing instruction to the specified IP fault box, and 1-way relay is closed. NC is connected to the function line and COM is connected to the ground line. After the relay is closed, it is a ground fault;

[0041] (4) Execute mixed line fault. Select 1 fault point by operating the electrical circuit simulation software 30 and click to send fault. Send 1 relay closing instruction to the specified IP fault box through the host computer, and 1 relay is closed. NC connects the function A line and COM connects the function B line. After the relay is closed, it is a mixed line fault;

[0042] An open circuit fault is to connect the cable to the common node and the normally closed node of the fault control box, and to achieve the on and off of the cable or node by issuing instructions; a short circuit fault is to connect the cable to the common node and the normally open node, and connect the normally open node and the common node after issuing instructions to achieve a short circuit effect; a grounding fault is to connect the common node of the grounding fault control box to the ground wire after looping through, and connect the normally open node to the line that needs to be grounded. After issuing instructions, the corresponding line is connected to the normally open node and the common end to achieve a grounding effect: a mixed line fault is to connect a driving power supply through the node in the fault control box, and connect the normally open node and the common node after issuing instructions. The driving power supply is used to drive the micro-relay to be sucked up and down, and the nodes on the micro-relay are looped with each other, so that the two lines cut off their own lines and then connect to another line to achieve the purpose of mixing lines.

[0043] For example, Figure 3 The relay protection circuit shown in the figure. Since the relay will generate instantaneous high voltage when it is disconnected, the high voltage generated when the relay is disconnected is absorbed by the diode to protect the relay from being burned.

[0044] In a possible embodiment, the interlocking software 60 can also collect circuit information in the virtual scene through the acquisition system, so that the driving module drives the device hardware to change the state. The interlocking software 60 changes the state of the relay group of the corresponding device in the virtual relay cabinet of the virtual scene by driving the acquisition module. The interlocking software 60 obtains the parameters used for electrical circuit operations in the configuration file of the electrical circuit simulation software 30, substitutes them into the corresponding circuit to edit the state formula, and outputs the state of each relay terminal and line in turn after calculation. The correspondence between the relay terminal state and the simulation signal device state is stored in a special local database. The data calculated by the electrical circuit simulation module takes out the corresponding simulation signal device 50 performance state enumeration in the local database through the corresponding value, and changes the device state in turn through the management module of the simulation signal device 50, thereby driving the simulation signal device 50.

[0045] In another possible embodiment, the interlocking software 60 can drive the state of the electrical circuit through the electrical circuit simulation software 30 to have an open circuit fault, a short circuit fault, a ground fault, and a mixed line fault. The states of the electrical circuit represent different simulated track control equipment fault states, and the electrical circuit states are all controlled by relays to change the device state in the virtual 3D simulation software 10; the fault software sends instructions to the fault control box, and the fault control box uses instructions to connect the common end to the normally open or normally closed node to achieve the connection and disconnection of the line:

[0046] Specifically, (1) executing the open circuit fault, select 1 fault point by operating the electrical circuit simulation software 30 and click to send the fault, and send 1 relay closing instruction to the specified IP fault box through the host computer, 1 relay is closed, NC and COM are connected to the function line, and the relay is closed to indicate an open circuit fault;

[0047] (2) Execute the short-circuit fault by operating the electrical circuit simulation software 30 to select a fault point and click to send the fault. The upper computer sends a relay closing instruction to the specified IP fault box, and the relay is closed. NO and COM are connected to the function line. After the relay is closed, it is a short-circuit fault;

[0048] (3) Execute the ground fault by operating the electrical circuit simulation software 30 to select 1 fault point and click to send the fault. The host computer sends a 1-way relay closing instruction to the specified IP fault box, and 1-way relay is closed. NC is connected to the function line and COM is connected to the ground line. After the relay is closed, it is a ground fault;

[0049] (4) Execute mixed line fault. Select 1 fault point by operating the electrical circuit simulation software 30 and click to send fault. Send 1 relay closing instruction to the specified IP fault box through the host computer, and 1 relay is closed. NC connects the function A line and COM connects the function B line. After the relay is closed, it is a mixed line fault;

[0050] An open circuit fault is to connect the cable to the common node and the normally closed node of the fault control box, and to achieve the on and off of the cable or node by issuing instructions; a short circuit fault is to connect the cable to the common node and the normally open node, and connect the normally open node and the common node after issuing instructions to achieve a short circuit effect; a grounding fault is to connect the common node of the grounding fault control box to the ground wire after looping through, and connect the normally open node to the line that needs to be grounded. After issuing instructions, the corresponding line is connected to the normally open node and the common end to achieve a grounding effect: a mixed line fault is to connect a driving power supply through the node in the fault control box, and connect the normally open node and the common node after issuing instructions. The driving power supply is used to drive the micro-relay to be sucked up and down, and the nodes on the micro-relay are looped with each other, so that the two lines cut off their own lines and then connect to another line to achieve the purpose of mixing lines.

The specific circuit of the communication module is as follows Figure 4 shown.

[0052] Optionally, in order to reduce signal interference, the rail control equipment fault simulation training system also includes: Figure 5 The photoelectric coupling amplifier circuit shown in the figure is used to protect and isolate the circuit and avoid signal interference through the photoelectric coupler. At the same time, the amplifier circuit at the rear stage plays a role in current amplification to drive the relay to work.
