Description

Technical Field

[0001] The utility model relates to the field of track circuit training equipment, and particularly relates to a track circuit training system supporting remote fault setting. Background Art

[0002] The track circuit is a safety basic equipment for ensuring the train operation control system, including a transmitter, a receiver, a lightning protection simulation network device, an attenuation redundancy controller, etc. The internal and external interfaces are complex and are interconnected by thousands of complex cables to transmit various control signals. To strengthen the construction of the maintenance and repair capabilities of employees, the vast majority of signal sections are equipped with track circuit training systems. However, the existing training systems have the following defects in function: 1. The operation of fault setting and fault recovery is complex: There is no dedicated fault training module. Limited by the cables and interfaces of the track circuit equipment itself, when setting faults, generally only some relatively simple fault forms can be simulated by installing on-site fault component modules, unplugging and plugging cable connectors, disconnecting the power supply, etc. The operation process is complex; when recovering from faults, it completely depends on manual operation. Before recovery, the system power supply needs to be disconnected, and after recovery, the power needs to be turned on for repeated inspection and confirmation. If multiple fault points are set at the same time, it is easy to miss the recovery. 2. The positions of fault points and the supported fault types are relatively limited: The positions of fault points are often limited to a small part of pre-set fixed node positions, with poor flexibility. On the one hand, many difficult faults on site cannot be reproduced in the training system, and on the other hand, it also limits the learning and operation scope of employees. After practicing for a short period of time, employees often form a thinking inertia and cannot fully explore and understand all aspects of the equipment, affecting the comprehensive understanding and handling ability of equipment faults. 3. It does not support remote fault setting: Every time a fault is set, full-time personnel need to cooperate on-site for operations such as repeated disassembly and welding of the same fault point, resulting in the decreasing concealment of the fault point position, increasing the operation difficulty and time cost. Excessive operation times may damage the training equipment, which may all limit the development of work such as technical competitions and practical operation examinations for employees. Therefore, there is a need for a track circuit training equipment that can meet the remote setting and recovery of various types of faults in the track circuit to remotely and comprehensively simulate relevant faults in the track circuit conveniently and quickly. Summary of the Invention

[0023] For the embodiment of the present utility model, refer to Figure 1As shown in the figure, a track circuit training system supporting remote fault setting is provided, which includes: several fault simulation training cabinets for simulating the faults of the track circuit in the training signal section base and obtaining simulation data. Each fault simulation training cabinet is set in the corresponding training signal section base. Each fault simulation training cabinet includes indoor equipment for simulating track circuit faults, outdoor equipment for simulating track circuit faults, and a simulation training host electrically connected to the indoor equipment for simulating track circuit faults and the outdoor equipment for simulating track circuit faults respectively; several training terminals, each training terminal is communicatively connected to the fault simulation training cabinet in the corresponding training signal section base, and can remotely receive and process the fault simulation data of the corresponding fault simulation training cabinet in the form of a man-machine interaction interface. Each training terminal includes a fixed training terminal and a mobile training terminal; a training center server, communicatively connected to each training terminal, for storing and managing and controlling the fault simulation data of the fault simulation training cabinets within its jurisdiction.

[0024] The common fault simulation types of the indoor equipment for simulating track circuit faults are as follows: open circuit of the transmitter power supply, open circuit of the transmitter direction selection, open circuit / short circuit of the transmitter low-frequency code selection, open circuit / short circuit of the transmitter carrier frequency selection, open circuit / short circuit of the -1 / -2 selection condition, open circuit / short circuit of the transmitter transmission line, open circuit / short circuit of the FBJ contact, open circuit / short circuit of the receiver carrier frequency selection condition, open circuit of the connection line between the receiver and the attenuator, open circuit of the receiver XGJ / XGJH, open circuit / short circuit of the track circuit signal of the attenuator, open circuit / short circuit of the GJ relay, open circuit / short circuit of the direction-changing relay, etc.

[0026] When designing the hardware of the indoor / outdoor equipment, two different types of fault setting and recovery circuit boards, namely type B and type C, can be used according to the voltage characteristics of the wiring points. Among them, the type B fault setting and recovery circuit board is used to control the faults related to the voltage interfaces below 380V in the ground equipment cabinet, and the type C fault setting and recovery circuit board is used to control the wiring faults between the ground equipment cabinets and between the ground equipment cabinet and the outdoor equipment.

[0027] Inside the indoor and outdoor equipment for simulating track circuit faults, an integrated fault setting and recovery circuit board is adopted. This circuit board can use existing mature products, which are specifically divided into two parts: a CPU board and a bottom board. Among them, the interfaces and circuits of the CPU board are as Figure 2 and 3 shown, and the bottom board circuit is as Figure 4As shown. The circuit boards can be cascaded using the RS485 bus, and the quantity can be flexibly configured according to the total number of nodes required for the faults and the number of faulty nodes of each type. Specifically, the types of fault points to be set can be divided into states such as short circuit, open circuit, poor contact, and abnormal capacitive reactance. According to the requirements of the fault types to be finally simulated, the corresponding fault setting points are accessed. The same fault access point can support the simultaneous access of multiple different types of fault setting points.

[0028] Designed with a distributed structure in combination with the characteristics of indoor equipment of the track circuit, its internal integrated fault setting and recovery circuit board is connected to each input and output node of the relay on the combination rack of the indoor equipment cabinet of the track circuit.

[0030] The training control host communicates with the training terminal through Ethernet or WiFi to receive fault setting and recovery instructions; communicates with the indoor equipment for fault simulation through the RS485 bus and communicates with the outdoor equipment for fault simulation through LORA wireless, and realizes the setting and recovery of relevant faults of the track circuit according to the received instructions.

[0031] In the embodiment of this case, control points can be set at key operation points of the track circuit. During the training process, the points to be accessed such as various fault types, cables, switches, etc. are introduced into the fault simulation training cabinet, and remote control is realized through methods such as WiFi / 4G / LORA wireless network, RS485, and Ethernet. Flexible setting of various types of faults such as cable continuity, mixing, and impedance exceeding the limit is realized, and remote setting and recovery of various types of faults are achieved. The data of each control point is collected in real time through the circuit board and transmitted back to the central server for storage and analysis.

[0032] Furthermore, the fault setting and recovery circuit board can be fixed in the fault simulation training cabinet through the installation component; the installation component includes: a plurality of cascading housings 1 corresponding to a plurality of fault setting and recovery circuit boards cascaded through the RS485 bus. The number of each cascading housing is the same as the number of cascaded fault setting and recovery circuit boards according to requirements. A unit accommodation cavity for clamping and fixing the fault setting and recovery circuit board is arranged in each cascading housing 1, and a mounting bracket fixed to the housing 1 for fixedly installing the housing with the clamped fault setting and recovery circuit board on the inner wall of the fault simulation training cabinet is provided.

[0033] Specifically, referring to Figure 5 and 6 As shown, the mounting bracket includes: a U-shaped connecting plate 2 and a C-shaped connecting piece 3; the U-shaped connecting plate 2 includes a back plate fixed to the side of the cascading housing through fasteners and two side plates symmetrically arranged above and below the back plate. Strip-shaped holes for detachably fixing the C-shaped connecting piece are formed on both side plates, and mounting holes for mounting and fixing with the fault simulation training cabinet are formed on the C-shaped connecting piece 3, making cascading installation and disassembly more convenient.

[0034] Heat dissipation holes 4 can be arranged on the side walls of each cascading housing. At the same time, a row of interface mounting holes 5 for connecting the interfaces of the circuit board can be arranged on the cascading housing. The simulation training host can be an industrial control computer. The fixed training terminal can be a desktop computer communicating with the simulation training host and the training center server through Ethernet, and the mobile training terminal can be a portable terminal device communicating with the simulation training host and the training center server through a wireless communication network. The wireless communication network can be a WIFI wireless network, or a combined network composed of a WIFI wireless network and a mobile data traffic network.
