Description

Technical Field

[0001] This utility model relates to the field of railway transportation equipment technology, and in particular to a tail-end host based on CPCI architecture. Background Technology

[0002] The train rear safety protection device is a special transportation safety device developed to improve the safety of railway transportation when the rear of a freight train is unattended after the removal of the guard car. The device uses computer coding, wireless remote control, voice synthesis and computer processing technology to ensure the safe operation of the train. It is also an important railway operation equipment.

[0003] Existing controllable tail-of-train safety protection devices include a wind pressure sensor and an exhaust solenoid valve. The wind pressure sensor detects the wind pressure at the tail of the train, and the exhaust solenoid valve executes exhaust operations based on exhaust command signals from the main control room. The controllable tail-of-train safety protection device also includes a wireless communication module connected to the wind pressure sensor and the exhaust solenoid valve control circuit. This module transmits the wind pressure data detected by the wind pressure sensor to the main control room and receives exhaust command signals from the main control room. The controllable tail-of-train safety protection device makes information transmission more secure and reliable to a certain extent, overcomes the influence of harsh environments, effectively reduces data transmission latency, and achieves real-time and precise exhaust operations. However, its structural stability still needs improvement.

[0004] Currently, the mainframes used in the field generally employ a multi-part circuit board assembly method, resulting in a complex structure, inconvenient maintenance, numerous fixing screws during assembly, poor impact and vibration resistance, and the possibility of screws loosening during prolonged use, leading to component disintegration and affecting normal operation. Due to the limitations of the assembly structure, the circuit boards cannot be reliably electromagnetically shielded, resulting in poor anti-interference capabilities. Furthermore, the circuit board design suffers from low performance and poor data processing capabilities, making it unable to meet the requirements of high-speed and complex communication.

[0030] Please refer to the following: Figures 1 to 4 The tail host based on CPCI architecture provided by this utility model will now be described.

[0031] The CPCI (CompactPCI) architecture is a high-performance industrial computer bus standard proposed by the PCI Industrial Computer Manufacturers' Group (PICMG) in 1994. The following are some key features and application areas of the CPCI architecture:

[0032] Electrical characteristics: The CPCI bus is based on the PCI electrical specification and is compatible with bus technologies such as VME, enabling PC-based x86 architecture, hard disk storage and other technologies to be used in industrial fields.

[0033] Mechanical Structure: CPCI uses Euro-K connectors and standard 3U and 6U board sizes, providing excellent shock resistance and ventilation. It also supports board removal from the front panel for easy replacement and maintenance.

[0034] Hot-swap technology: CPCI supports hot-swap, which means that function modules can be removed or inserted without power interruption and without affecting the normal operation of the system.

[0035] Openness and reliability: CPCI is highly open and reliable, supporting plug-and-play functionality, enabling telecommunications equipment to utilize the same advanced technologies as desktop application systems.

[0036] Bandwidth: CPCI can provide up to 512MB per second of bandwidth under a 64-bit / 66M bus interface, supporting the same interface chips as desktop PCs and workstations.

[0037] Application areas: CPCI is widely used in communication, networking, computer telephony integration, real-time system control, industrial automation, real-time data acquisition, military systems and other application areas that require high-speed computing, intelligent transportation, aerospace, medical devices, water conservancy and other modular, high-reliability and long-term use applications.

[0038] The difference between CPCI and traditional industrial PCs: CPCI is superior to traditional industrial PCs in terms of durability, shock resistance, and ventilation, reducing maintenance time from hours to minutes, thus improving system availability and maintenance efficiency.

[0039] like Figure 1 and Figure 2 As shown, the tail-end host based on CPCI architecture provided by this utility model includes a housing 1, a CPCI information processing platform 2, an exhaust component 3, a battery component 4, a communication component 5, and a suspension device 6. The CPCI information processing platform 2 is disposed inside the housing 1 and electrically connected to the exhaust component 3, the battery component 4, and the communication component 5. The communication module 52 of the communication component 5 is plugged into the CPCI information processing platform 2. The suspension device 6 is disposed outside the housing 1.

[0040] In this embodiment, as Figure 2 and Figure 3As shown, the CPCI information processing platform 2 includes a CPCI motherboard 21, a CPU plug-in 23, a positioning plug-in 22, and a rack 24. The CPCI motherboard 21 is fixed to the rack 24, and the CPU plug-in 23 and the positioning plug-in 22 are both plugged into the CPCI motherboard 21. The CPCI information processing platform 2 adopts standard 3U plug-ins, and each board is installed in a 3U rack, which is simple in structure and highly reliable; maintenance is simple, and board replacement only requires plugging and unplugging. The positioning plug-in 22 is equipped with a positioning module 221, which includes GPS and Beidou positioning function modules. Data communication and power supply between the plug-ins of the CPCI information processing platform 2 are exchanged through the CPCI motherboard 21, and each plug-in is plugged into the base of the CPCI motherboard 21; this method reduces internal cable connections, simplifies installation steps, and also reduces the risk of cable detachment due to vibration during use, thus improving the reliability of the equipment. The data bus of the CPCI motherboard 21 uses a PCB (Printed Circuit Board) anti-interference design and multi-layer board routing, which improves the anti-interference capability of data communication and is suitable for use in complex communication applications.

[0041] Specifically, the CPU plug-in 23 includes three information processing plug-ins 231 and one general control plug-in 232.

[0042] like Figure 3 As shown, the frame includes a front side plate 241, a rear side plate 242, and a connecting plate 243. The connecting plate 243 connects the front side plate 241 and the rear side plate 242 to form a frame structure. Several guide rail grooves are arranged opposite each other on the front side plate 241 and the rear side plate 242. Figure 2 As shown, the connecting plate 243 at the top has an opening in the middle to allow space for the communication module 52. The two front and rear side plates are fixed at multiple points by the connecting plate 243, and each board has a guide groove, which provides good impact and vibration resistance.

[0043] In this embodiment, the exhaust assembly 3 includes a set of exhaust solenoid valves, three sets of air pressure sensors, and an exhaust pipe 31, located at the bottom of the housing 1. The exhaust solenoid valves are connected to the exhaust pipe 31. The exhaust solenoid valves and the air pressure sensors are used for tail-end exhaust and pressure acquisition, respectively. The three sets of air pressure sensors are used to employ a "two-out-of-three" signal method to improve detection accuracy.

[0044] like Figure 2As shown, the battery assembly 4 includes a battery compartment 41 and a pull-out battery 42. The pull-out battery 42 is detachably connected to the battery compartment 41. The battery compartment 41 is located inside the housing 1, between the CPCI information processing platform 2 and the exhaust assembly 3.

[0045] In this embodiment, the communication component 5 includes an antenna unit 51 and a communication module 52, such as... Figure 3 As shown, the communication module 52 consists of two parts: a 400MHz radio module and an LTE-R communication module, located at the top of the CPCI information processing platform 2. LTE-R (Long Term Evolution for Railway) is a wireless communication technology specifically designed for railway communication. It is based on LTE (Long Term Evolution) technology and optimized and customized for the specific needs of the railway industry.

[0046] Specifically, such as Figure 2 As shown, the antenna unit 51 is located at the top of the housing 1 and includes a 400MHz antenna, two positioning module antennas and two LTE-R antennas.

[0047] like Figure 1 As shown, the column tail host based on CPCI architecture 2 also includes a display component 7, which is located on the front of the housing 1 and includes a flashing component and an LED digital tube. It is used to display setting information and alarm information.

[0048] In this embodiment, the suspension device 6 consists of a suspension lock, upper and lower latches, and a locking mechanism, and is located on the side of the housing. One of the upper and lower latches is a movable latch, and the other is a fixed latch. The locking mechanism is used to restrict the movement of the movable latch. The suspension device 6 is used to suspend the tail unit to the rear of the train.

[0049] like Figure 4 As shown in this embodiment, the CPCI motherboard 21 of the CPCI information processing platform 2 is provided with one socket for the positioning plug-in 22, two sockets for the communication module 52, and four sockets for the CPU plug-in 23 (three information processing plug-ins 231 and one general control plug-in 232). However, these quantities are only an example and can be increased or decreased according to specific functional requirements.

[0050] In summary, this utility model adopts a modular design using a CPCI architecture, resulting in high reliability, strong anti-interference capability, and good vibration resistance in the circuitry of the tail host. This significantly reduces the failure rate during long-term operation, and the modules do not interfere with each other, facilitating maintenance and greatly reducing maintenance time. Because it uses the CPCI information processing platform, its information processing capability is greatly enhanced compared to traditional tail hosts, making it ideal for complex communication applications, such as controllable tail hosts for functional safety.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
