Description

Technical Field

[0001] This application relates to the field of locomotive onboard data processing technology, and in particular to a locomotive onboard data management system. Background Technology

[0002] The train is equipped with various data acquisition devices to collect train operating parameters in a timely manner. Commonly used train data acquisition devices include the locomotive operation monitoring and recording device (LKJ), the locomotive integrated wireless communication equipment (CIR), and the locomotive signaling equipment. These devices collect train operating parameters and store them in their local memory.

[0003] Because trains are in operation most of the time, timely data transfer is not possible. Furthermore, some equipment files are large and involve network security issues, making wireless data transfer inconvenient. The current method involves ground staff carrying transfer media compatible with each data acquisition device to the locomotive for manual data transfer. Specifically, ground staff insert an IC card into the locomotive's operation monitoring and recording device (LKJ) and a USB flash drive into the locomotive's integrated wireless communication equipment (CIR) and signaling equipment. Data from each device is transferred to the IC card or USB flash drive, and then the transfer media is brought to the ground. The data from the transfer media is then transferred to ground-based computer equipment for analysis.

[0004] As can be seen from the existing technology described above, the data transfer process is inconvenient and has low efficiency. Utility Model Content

[0005] The purpose of this application is to provide a locomotive onboard data management system to solve the problems of inconvenient and inefficient data transfer of locomotives as described in the background art.

[0006] To achieve the above objectives, this application provides the following solution: This application provides a locomotive onboard data management system, including a centralized data transfer device, a centralized data transfer USB flash drive, and a locomotive operation monitoring data wireless transmission device host (TSC).

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the contents of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See Figure 1This application provides a locomotive onboard data management system, including a centralized data transfer device, a centralized data transfer USB flash drive, and a locomotive operation monitoring data wireless transmission device host (TSC). The managed equipment includes the locomotive operation monitoring and recording device LKJ, the locomotive integrated wireless communication equipment CIR, and the locomotive signaling equipment; The LKJ is connected to the TSC; The TSC is equipped with an Ethernet communication interface, referred to as the first Ethernet communication interface, and the centralized transfer device is equipped with an Ethernet communication interface, referred to as the second Ethernet communication interface; the first Ethernet communication interface of the TSC is connected to the second Ethernet communication interface of the centralized transfer device. The centralized transfer device is also equipped with three USB communication interfaces, referred to as the first USB communication interface, the second USB communication interface, and the third USB communication interface; the CIR is equipped with a fourth USB communication interface; the locomotive signaling equipment is equipped with a fifth USB communication interface; and the centralized transfer USB flash drive is equipped with a sixth USB communication interface. The fourth USB communication interface of the CIR is connected to the first USB communication interface of the centralized transfer device, and the fifth USB communication interface of the locomotive signaling equipment is connected to the second USB communication interface of the centralized transfer device. The third USB communication interface of the centralized dumping device is connected to the sixth USB communication interface of the centralized dumping USB flash drive.

[0021] The train operation monitoring and recording device LKJ is used to monitor the train's operating status, record operating data, and issue alarms or take control measures when speeding or violating regulations. LKJ is an abbreviation of the first letters of the pinyin alphabet: L (train), K (control), and J (monitoring).

[0022] LKJ is an inherent device on the locomotive. Since it does not have any other extra communication interfaces, it is connected to TSC via CAN communication, and then TSC and centralized data transfer are connected via User Datagram Protocol (UDP).

[0023] The abbreviation for Cab Integrated Radio communication equipment (CIR) is used to enable voice communication and data transmission between locomotives and the ground, as well as other locomotives.

[0024] Among them, the locomotive signaling equipment is a signal receiving and display device installed on the locomotive, used to receive signals sent by ground signaling equipment and display the corresponding signal information in the driver's cab.

[0025] Among them, the Locomotive Operation Monitoring Data Wireless Transmission Device (TSC) host is also an inherent device on the locomotive. It can be the TSC2 type Locomotive Operation Monitoring Data Wireless Transmission Device host, which is used to receive data sent by LKJ, cache it, and respond to the data request when it is received, forwarding it to the centralized dumping device via UDP protocol.

[0026] The centralized dumping device is used to receive data sent by the TSC and forward it to the centralized dumping USB drive. The centralized dumping device is also used to connect the CIR and the centralized dumping USB drive, so that the CIR and the centralized dumping USB drive are connected via USB communication, and the CIR sends data to the centralized dumping USB drive.

[0027] Furthermore, the centralized data transfer device is also used to connect the locomotive signaling equipment to the centralized data transfer USB drive, enabling the locomotive signaling equipment to send data to the centralized data transfer USB drive.

[0028] The first USB communication interface and the second USB communication interface can be the same communication interface, which can be a DB15 physical component. In this case, a DB15 to two USB interface cables are required.

[0029] The second Ethernet communication interface can be an M12 communication interface. Therefore, an M12 to M8 network communication cable is required to connect the TSC and the centralized transfer device.

[0030] The working process of the locomotive on-board data management system provided in this embodiment is as follows: LKJ, CIR and locomotive signaling equipment collect relevant data from the locomotive in real time; When it is necessary to transfer data collected by LKJ, CIR and locomotive signaling equipment, staff bring a centralized transfer USB flash drive to the locomotive and connect the centralized transfer USB flash drive to the third USB communication interface of the centralized transfer device; When the centralized data dumping device receives a data dumping instruction from the LKJ device, it sends a data dumping request to the TSC. The TSC receives the data dumping request and sends the cached data collected by the LKJ device to the centralized data dumping device via Ethernet and based on the UDP protocol. The centralized data dumping device then sends the data to the centralized data dumping USB flash drive. When the centralized data transfer device receives a data transfer instruction from the CIR device, the centralized data transfer device controls the CIR analog switch to connect the first USB communication interface to the third USB communication interface, thereby connecting the CIR device to the centralized data transfer USB flash drive, and enabling the CIR device to send the collected data to the centralized data transfer USB flash drive. When the centralized data transfer device receives a data acquisition command from the locomotive signaling equipment, the centralized data transfer device controls the locomotive signaling analog switch to connect the second USB communication interface with the third USB communication interface, thereby connecting the locomotive signaling equipment with the centralized data transfer USB flash drive, and enabling the locomotive signaling equipment to send the acquired data to the centralized data transfer USB flash drive; Through the above three processes, the data collected by LKJ, CIR and locomotive signaling equipment has been sent to the centralized data transfer USB drive. The staff can then take the centralized data transfer USB drive off the locomotive for further data processing.

[0031] In addition, for each dump operation, after the file dump is completed, the centralized dump USB drive is disconnected from the currently connected CIR or locomotive signal equipment, and then connected to the centralized dump device, which renames the dumped files and puts them into the designated folder.

[0032] See Figure 3 TX11 is the USB communication interface located in the central dump. TX11 includes two USB communication interfaces, which are connected to the first USB communication interface and the second USB communication interface respectively. TX12 is the second Ethernet communication interface.

[0033] In addition, all the relevant content regarding the implementation of data forwarding between devices is existing technology, and can be found in the relevant existing technology. This application will not elaborate on it here.

[0034] The locomotive onboard data management system provided in this application includes a centralized data transfer device and a centralized data transfer USB drive. The centralized data transfer device receives data sent by the TSC (Traffic Signal Center) and forwards it to the centralized data transfer USB drive. The centralized data transfer device also connects the CIR (Cyber-Instrument Controller) and the centralized data transfer USB drive, enabling the CIR to send data to the USB drive via USB communication. Furthermore, the centralized data transfer device also connects the locomotive signaling equipment to the centralized data transfer USB drive, allowing the locomotive signaling equipment to send data to the USB drive. Thus, using this centralized data transfer device and a centralized data transfer USB drive, data transfer from the LKJ (Locomotive Knocker), CIR, and locomotive signaling equipment can be achieved. In contrast, existing technologies require different centralized data transfer USB drives for different CIRs and locomotive signaling equipment, potentially leading to transfer failures. Therefore, compared to existing technologies, this application not only improves the convenience of data transfer but also increases the success rate of data transfer.

[0035] Optionally, the data collected by the LKJ equipment includes: LKJ time, locomotive model, locomotive number, A / B sections, train number, driver's employee number, co-driver's employee number, speed rating, load, passenger car, loaded car, empty car, non-operational car, substitute passenger car, LKJ monitoring software version number, locomotive wheel diameter, locomotive signal, operating speed, speed limit, and other real-time information.

[0036] Optionally, the centralized transfer device is also equipped with a processing unit, which can be a microcontroller unit (MCU). The MCU is connected to the transfer switch and is used to control the transfer switch to switch to HUB1 (corresponding to the first USB communication interface) or HUB2 (corresponding to the second USB communication interface). At this time, the centralized transfer USB disk will connect to the CIR or locomotive signal equipment to start the transfer. After the transfer is completed, the switch is switched to connect to the MCU and the files in the centralized transfer USB disk are sorted according to the vehicle type-locomotive number-AB section.

[0037] Among them, the microcontroller unit (MCU) is a chip-level computer that performs different combinations of control for different applications.

[0038] Optionally, an MCU analog switch is provided between the MCU and the centralized dump USB drive. When it is necessary to dump data on LKJ, the MCU controls the MCU analog switch to enable the MCU to communicate with the centralized dump USB drive, thereby sending the received data to the centralized dump USB drive.

[0039] Additionally, it should be noted that the MCU, MCU analog switch, and centralized dump USB flash drive are connected by default, and adjustments should be made as needed during use.

[0040] In this application, the dump switch includes LKJ dump switch, CIR dump switch, machine information dump switch and one-button dump switch.

[0041] Optionally, see Figure 2 and Figure 3 In another exemplary embodiment of this application, the centralized dumping device includes an LKJ dumping switch, which is connected to the processing unit of the centralized dumping device.

[0042] When the LKJ dump switch is pressed, the processing unit can send the relevant data of the LKJ to the centralized dump USB flash drive.

[0043] Optionally, see Figure 2 and Figure 3 In another exemplary embodiment of this application, the centralized dumping device further includes a CIR dumping switch connected to the processing unit of the centralized dumping device.

[0044] When the CIR dump switch is pressed, the processing unit connects the first USB communication interface to the third USB communication interface, and the CIR device can directly send the collected data to the centralized dump USB flash drive.

[0045] Optionally, see Figure 2 and Figure 3In another exemplary embodiment of this application, the centralized dumping device further includes a machine information dumping switch, which is connected to the processing unit of the centralized dumping device.

[0046] When the machine information transfer switch is pressed, the processing unit connects the second USB communication interface to the third USB communication interface, enabling the machine information device to directly send the collected data to the centralized transfer USB flash drive.

[0047] Optionally, see Figure 2 and Figure 3 In another exemplary embodiment of this application, the centralized dumping device further includes a one-button dumping switch, which is connected to the processing unit of the centralized dumping device.

[0048] When the one-button data transfer switch is pressed, the first USB communication interface, the second USB communication interface, the processing unit of the centralized data transfer device, and the third USB communication interface are connected to achieve the data transfer.

[0049] Furthermore, when using the one-click dump switch, three dump modes can be automatically switched, as follows: When the one-key transfer switch is pressed, the MCU in the centralized transfer device will receive the one-key transfer command, and then control the centralized transfer USB flash drive to connect directly or indirectly to the CIR and locomotive signal equipment in sequence, thereby realizing the function of sequential transfer of CIR and locomotive signal equipment; furthermore, it also controls the centralized transfer device to communicate with TSC to realize LKJ transfer.

[0050] The LKJ dump switch, CIR dump switch, machine-information dump switch, and one-button dump switch mentioned above are all common existing switching devices, as long as they can realize the switching of line connections.

[0051] Optionally, in another exemplary embodiment of this application, the centralized dumping device further includes an LKJ dumping indicator, a CIR dumping indicator, and a machine information dumping indicator, which are respectively connected to the MCU.

[0052] The MCU controls the LKJ dump indicator, CIR dump indicator, and machine information dump indicator to be on, flashing, or off respectively.

[0053] Furthermore, this indicator light can be an LED indicator light.

[0054] For example, when performing LKJ-related data dumping, the LKJ dump indicator light 02B flashes rapidly during the dumping process, and remains constantly lit after the dumping is completed.

[0055] When performing CIR-related data transfer, the CIR transfer indicator 02A will flash rapidly during the transfer process and remain on after the transfer is completed. If the connection of the centralized transfer USB flash drive is abnormal, the CIR transfer indicator 02A will flash slowly.

[0056] When transferring data related to locomotive signaling equipment, the locomotive signaling transfer indicator 03A will flash rapidly during the transfer process and remain on after the transfer is completed. If the connection of the centralized transfer USB flash drive is abnormal, the locomotive signaling transfer indicator 03A will flash slowly.

[0057] Optionally, in another exemplary embodiment of this application, the centralized storage device further includes a first nut and a fuse, the fuse being disposed in the first nut and connected between the power supply and the centralized storage device.

[0058] The first nut can be screwed onto the nut, thereby connecting the fuse between the power source and the central storage device.

[0059] Optionally, the centralized storage device is also equipped with a grounding wire for grounding the equipment housing to improve the safety of the centralized storage device.

[0060] Furthermore, the centralized transfer device is also equipped with a power switch and a power plug. Furthermore, the power plug can be a 110V power plug.

[0061] Optionally, in another exemplary embodiment of this application, the centralized dumping device is further provided with a housing for protecting the centralized dumping device, thereby improving the safety and extending the lifespan of the centralized dumping device.

[0062] Furthermore, all the aforementioned switches, buttons, etc., can be mounted on the casing for user convenience.

[0063] Furthermore, a base is provided at the lower end of the outer casing, and a slide rail is provided on the base, so that the outer casing can move on the slide rail, thereby achieving the purpose of moving the centralized storage device.

[0064] In addition, the slide rail is equipped with mounting holes for mounting the base onto the locomotive.

[0065] Optionally, see Figure 1 In another exemplary embodiment of this application, the system further includes at least one computer device. For example, it includes two computer devices, namely a first computer and a second computer.

[0066] At least one computer is set up at the ground station, and each computer is equipped with a USB communication interface for connecting a centralized data transfer USB flash drive. This allows the data in the centralized data transfer USB flash drive to be transferred to the computer equipment, making it convenient for staff to process the data in the centralized data transfer USB flash drive.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
