[0002] Cab Integrated Radio Communication Equipment (CIR), also known as locomotive radio or locomotive-mounted radio, is a communication device widely used on railways. At the same time, railways are equipped with CIR inspection stations (also known as inspection equipment) to perform various functional tests on the CIR when train sets / locomotives enter and leave the depot.

[0003] Existing railway locomotive onboard radios mainly adopt two working modes: GSM-R mode and 450MHz mode. Therefore, the locomotive onboard radio's entry and exit detection communication method mainly realizes voice and data function detection through two channels: GSM-R network and 450MHz analog radio.

[0004] However, due to the low data rate of the GSM-R network itself and the lack of continuous transmission capability of the 450MHz system, the dual-system locomotive radio entry and exit detection method based on the GSM-R system and the 450MHz system does not have high-speed data transmission capability. It cannot transmit detection data that can be used for more detailed fault diagnosis, and it requires more time to complete the acquisition and transmission of detection data, resulting in the defects of long time consumption and low detection efficiency. Summary of the Invention

[0009] According to the locomotive radio entry and exit detection system provided by the present invention, the service connection status data includes network interface status data, trunk service status data and vehicle terminal connection status data. The analysis results based on the service connection status data determine the abnormality of the inbound / outbound detection connection service, including: If any of the analysis results of the network interface status data, the cluster service status data, and the vehicle terminal connection status data are abnormal, the inbound / outbound detection connection service is determined to be abnormal.

[0010] According to the locomotive radio entry / exit detection system provided by the present invention, the step of sending the service connection status data to the entry / exit detection server through the primary or backup link of the LTE-M network includes: If, based on the analysis results of the service connection status data, it is determined that the inbound / outbound detection connection service is abnormal, the service connection status data will be sent to the inbound / outbound detection server via the backup link of the LTE-M network; or, after a preset retry waiting time, the service connection status data will be sent to the inbound / outbound detection server via the primary link of the LTE-M network.

[0011] According to the locomotive radio entry and exit detection system provided by the present invention, the step of sending the detection data packet through an LTE-M network includes: The detection data packet is sent to the LTE-M base station of the LTE-M network, and the LTE-M base station verifies whether the detection terminal device belongs to the base station authorized device based on the detection data packet; If the detection terminal device is verified to be an authorized device of the base station, the detection data packet is sent to the LTE-M operator server of the LTE-M network, and the LTE-M operator server verifies whether the detection terminal device is an authorized device of the operator based on the detection data packet. If the detection terminal device is verified to be an operator-authorized device, the detection data packet is sent to the inbound / outbound detection server; The step of generating a locomotive radio entry / exit detection report based on the detected data packet includes: Based on the detection data packet, verify whether the detection terminal device belongs to the target detection device; If the detection terminal device is verified to be the target detection device, the detection data packet is parsed and analyzed to generate a locomotive radio entry and exit detection report.

[0016] The locomotive radio entry / exit detection system provided by this invention achieves data packet transmission between the terminal detection equipment at the terminal layer and the entry / exit detection server at the platform layer based on the LTE-M network. This allows the system to leverage the LTE-M network's support for VoLTE voice encoding and synchronous transmission of detailed voice signal parameters to meet the high-definition voice detection requirements between the locomotive radio and the inspection equipment. Furthermore, the system utilizes the high-speed real-time data transmission capability of the LTE-M network to transmit RF hardware self-test parameters in real time, enabling more accurate fault diagnosis, such as distinguishing between hardware failures and parameter drift. Additionally, the system leverages the LTE-M network's support for bidirectional short message transmission and continuous data stream transmission to simulate data interaction scenarios such as dispatch command issuance during actual operation, thereby acquiring simulated interactive detection data. This results in a locomotive radio entry / exit detection solution that is faster, more efficient, and more accurate. Attached Figure Description

Obviously, the drawings described below are some embodiments of this invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0018] Figure 1 This is one of the structural schematic diagrams of the locomotive radio entry and exit detection system provided by the present invention.

[0019] Figure 2 This is the second structural schematic diagram of the locomotive radio entry and exit detection system provided by the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] It should be noted that, in the description of this invention, the term "comprising" or any other variations thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The following is combined Figures 1-2 This invention describes the locomotive radio entry and exit detection system provided by the present invention.

[0023] Existing railway locomotive onboard radios mainly adopt two working modes: GSM-R mode and 450MHz mode. Therefore, the locomotive onboard radio's entry and exit detection communication method mainly realizes voice and data function detection through two channels: GSM-R network and 450MHz analog radio.

[0024] However, the inbound / outbound detection communication method based on both GSM-R network and 450MHz analog radio channels has several problems in terms of detection efficiency, resource consumption, environmental adaptability, and anti-interference capability.

[0025] First, the dual-system testing based on the GSM-R and 450MHz systems is time-consuming and insufficient to handle high-frequency maintenance pressure. For example, assuming the automatic testing process of the GSM-R system takes 4 minutes, the automatic testing process of the 450MHz system takes 3 minutes, and the joint debugging of the GSM-R and 450MHz systems takes 1 minute, then the main process of CIR self-testing takes a total of 8 minutes per unit. If the station has more than 50 locomotives entering and leaving the depot daily, a single testing line will take more than 6.5 hours per day, which is difficult to meet the high-efficiency turnover requirements during peak periods (such as the morning peak departure period).

[0026] Furthermore, the reason why the dual-system detection based on GSM-R and 450MHz systems takes a long time is because the GSM-R network itself has a low data rate and the 450MHz system lacks continuous transmission capability and high-speed data transmission capability. Therefore, more time is needed to complete the acquisition and transmission of detection data. At the same time, the entry and exit detection method of the dual-system based on GSM-R and 450MHz systems cannot transmit detection data that can be used for more detailed fault diagnosis because it lacks high-speed data transmission capability. Moreover, the GSM-R system only supports the outdated FR / EFR voice coding, and the voice bandwidth (300-3400Hz) of the 450MHz system is narrow, both of which cannot meet the requirements of high-definition voice detection. Therefore, the dual-system based on GSM-R and 450MHz systems need to spend more time on locomotive radio entry and exit detection to maintain detection accuracy.

[0027] Secondly, the 450MHz system has a potential for frequency conflict during frequency band detection. Generally, the 450MHz system uses a detection logic of "matching frequencies according to the locomotive's line," but some railway lines reuse frequencies (e.g., adjacent branch lines share the 457.725MHz uplink frequency). When multiple locomotives from different lines simultaneously enter the same detection area, frequency interference can easily occur between the ground-based inspection equipment and the onboard radio, leading to packet loss in the detection data transmission (e.g., signaling decoding success rate drops below 90%). This necessitates manual intervention to adjust the frequency, further extending the detection time.

[0028] Furthermore, the communication links of the GSM-R system lack backup redundancy and fault tolerance mechanisms. Under GSM-R network conditions, the channels lack redundancy mechanisms, leading to detection interruptions when the network environment is poor or communication is abnormal, and the system lacks fault tolerance mechanisms.

[0029] Furthermore, the detection accuracy of both GSM-R and 450MHz systems decreases in weak signal and complex electromagnetic environments.

[0030] For GSM-R systems, when there are electromagnetic interference sources such as high-voltage power lines and communication base stations in the detection area, the Public Land Mobile Network (PLMN) signal transmitted by the ground base station simulator is easily affected by clutter, resulting in a decrease in the CIR network attachment success rate (which can drop below 95% in extreme cases). Furthermore, when simulating weak field environments (such as RSCP=-105dBm), the accuracy error (±2dB) of the signal attenuator will further amplify the detection deviation, making it impossible to accurately determine the actual weak field adaptability of the equipment.

[0031] For a 450MHz system, the 450MHz frequency band is an open band and is susceptible to interference from external signals such as civilian walkie-talkies and industrial equipment, which can cause fluctuations in the measured transmission power. For example, the actual measured power of a nominal 5W may fluctuate between 4.2W and 5.8W. If this exceeds the standard error range of ±10%, it will affect the accuracy of the test results.

[0032] Finally, the 450MHz system suffers from insufficient stability under extreme temperature and humidity conditions. For example, in the high humidity environment of the rainy season, the connectors of the 450MHz low-loss RF line are prone to moisture and oxidation, increasing signal transmission loss and resulting in lower transmit power detection values. Frequent cleaning and maintenance are required to ensure detection accuracy.

[0033] In view of this, the present invention provides a locomotive radio entry and exit detection system to solve at least one of the aforementioned problems.

[0034] Figure 1 This is one of the structural schematic diagrams of the locomotive radio entry and exit detection system provided by the present invention, such as... Figure 1 As shown, the locomotive radio entry and exit detection system includes, but is not limited to, detection terminal equipment 110, entry and exit detection server 120, and application interaction panel 130.

[0035] Among them, the detection terminal equipment 110 is used to collect raw detection data, determine the detection data packet based on the raw detection data, and send the detection data packet through the LTE-M network.

[0036] The inbound / outbound detection server 120 is used to receive and store detection data packets, and generate locomotive radio inbound / outbound detection reports based on the detection data packets.

[0037] The application interaction panel 130 is used to respond to the report reading operation of the operation and maintenance personnel, pull the locomotive radio entry and exit detection report from the entry and exit detection server 120, and display the locomotive radio entry and exit detection report.

[0038] The detection terminal equipment 110 includes a locomotive onboard radio 111 and a warehouse inspection device 112; the raw detection data includes radio frequency hardware self-test data collected by the locomotive onboard radio 111, analog interactive detection data collected by the warehouse inspection device 112, and VoLTE voice detection data collected by the warehouse inspection device 112; the analog interactive detection data and VoLTE voice detection data are obtained based on the interactive detection between the onboard radio 111 and the warehouse inspection device 112.

[0039] Optionally, the detection terminal equipment 110 includes at least one locomotive-mounted radio 111 and at least one warehouse inspection device 112.

[0040] The radio frequency and hardware self-test data include the radio frequency self-test parameters and hardware self-test parameters of the locomotive radio 111; the radio frequency self-test parameters include, but are not limited to, at least one of the parameters such as transmit power waveform and receive sensitivity curve; the hardware self-test parameters include, but are not limited to, at least one of the parameters such as clock frequency, memory usage rate and other CPU operating status, microphone pickup sensitivity, speaker output power and audio signal transmission delay.

[0041] The simulated interactive detection data is based on data interaction scenarios such as the issuance of scheduling commands between the locomotive onboard radio 111 and the depot inspection equipment 112 in simulated actual operation. It is obtained through bidirectional short message transmission and continuous data stream transmission between the locomotive onboard radio 111 and the depot inspection equipment 112. Specifically, it includes, but is not limited to, at least one of the following dynamic indicators: packet loss rate, latency, bit error rate, communication establishment time, transmission success rate, and retransmission rate.

[0042] VoLTE voice detection data is based on VoLTE voice calls between the locomotive onboard radio 111 and the depot inspection equipment 112 in simulated actual operation, and is obtained through call quality verification and objective sound quality scoring. Specifically, it includes, but is not limited to, at least one of the following indicators: voice signal spectrum, echo suppression parameters, voice coding type (such as AMR-WB), voice coding parameters, end-to-end latency, etc.

[0043] The entry / exit detection server 120 is used for processing detection data, batch configuring network devices, and monitoring service status in locomotive entry / exit scenarios, ensuring that the communication function of the locomotive's onboard radio meets safe operation standards.

[0044] The application interaction panel 130 is an application interface used for operation and maintenance personnel to interact with each other. Specifically, it can be an interactive interface provided by devices such as industrial control computers, mobile phones, and computers through the installation of applications.

[0045] It is understandable that the data transmission between the detection terminal device 110 and the inbound / outbound detection server 120 is generally achieved through an LTE-M network connection; the data transmission between the inbound / outbound detection server 120 and the application interaction panel 130 can be achieved through either an LTE-M network or an electrical connection.

[0046] Specifically, Figure 2 This is the second structural schematic diagram of the locomotive radio entry and exit detection system provided by the present invention, combined with... Figure 1 and Figure 2As shown, after the locomotive radio entry / exit detection system starts working, on the one hand, the locomotive-mounted radio 111, located at the terminal layer, performs automatic detection and collects radio frequency hardware self-test data; on the other hand, the depot inspection device 112, also located at the terminal layer, and the locomotive-mounted radio 111 conduct interactive detection via the LTE-M network based on data interaction scenarios such as the issuance of dispatch commands in actual operation, and collect simulated interactive detection data; furthermore, the depot inspection device 112 and the locomotive-mounted radio 111 also conduct VoLTE voice call interactive detection via the LTE-M network, and collect VoLTE voice detection data. In other words, both the simulated interactive detection data and the VoLTE voice detection data are obtained by the interaction detection between the onboard radio 111 and the depot inspection device 112 via the LTE-M network.

[0047] At the terminal layer, each detection terminal device 110 collects the corresponding type of raw detection data, directly uses the raw detection data to generate detection data packets, or encrypts the raw detection data, adds redundant data, etc., before generating detection data packets. At the network layer, the detection data packets are sent to the inbound / outbound detection server 120 at the platform layer via the LTE-M network. More specifically, the detection data packets sent by the detection terminal device 110 are transmitted to the core network via the Uu interface of the LTE-M base station in the LTE-M network, and then transmitted to the detection data sub-server 121 in the inbound / outbound detection server 120 via the S1 interface of the core network.

[0048] The detection data sub-server 121 in the platform layer's inbound / outbound detection server 120 receives and stores detection data packets, performs compliance checks on the raw detection data in the detection data packets, such as data format verification and parameter threshold comparison, and generates a locomotive radio inbound / outbound detection report. This report includes, but is not limited to, the pass / fail results, abnormal results, and fault details for each inbound / outbound detection item.

[0049] At the application layer, after the locomotive radio entry and exit inspection report is generated, the application interaction panel 130 responds to the report reading operation that the maintenance personnel have scheduled in advance or entered in real time. It retrieves the locomotive radio entry and exit inspection report from the entry and exit inspection server 120 and displays at least one of the qualified results, abnormal results, and fault details of each entry and exit inspection item in the locomotive radio entry and exit inspection report, so that the maintenance personnel can obtain abnormal results and fault details in a timely manner and perform fault troubleshooting and maintenance.

[0050] Optionally, the detection data package includes a record table of locomotive radio entry and exit detection results generated based on simulated interaction detection data and VoLTE voice detection data, to support historical data backtracking and querying.

[0051] Optionally, the detection terminal equipment also includes a trunking service terminal for scheduling communication between multiple locomotive onboard radios and multiple depot inspection equipment.

[0052] In the dual-system locomotive radio entry and exit detection based on GSM-R and 450MHz systems, neither GSM-R nor 450MHz has high-speed data transmission capability. GSM-R has a low data transmission rate, and 450MHz lacks continuous transmission capability, does not support bidirectional short message transmission and continuous data stream transmission, and both have the defect of being unable to reproduce real data communication scenarios. At the same time, the FR / EFR voice coding format supported by GSM-R is outdated, and the 450MHz voice bandwidth is narrow, only 300-3400Hz, neither of which can meet the requirements of high-definition voice detection.

[0053] The locomotive radio entry / exit detection system provided by this invention achieves data packet transmission between the terminal detection equipment at the terminal layer and the entry / exit detection server at the platform layer based on the LTE-M network. This allows the system to leverage the LTE-M network's support for VoLTE voice encoding and synchronous transmission of detailed voice signal parameters to meet the high-definition voice detection requirements between the locomotive radio and the inspection equipment. Furthermore, the system utilizes the high-speed real-time data transmission capability of the LTE-M network to transmit RF hardware self-test parameters in real time, enabling more accurate fault diagnosis, such as distinguishing between hardware failures and parameter drift. Additionally, the system leverages the LTE-M network's support for bidirectional short message transmission and continuous data stream transmission to simulate data interaction scenarios such as dispatch command issuance during actual operation, thereby acquiring simulated interactive detection data. This results in a locomotive radio entry / exit detection solution that is faster, more efficient, and more accurate.

[0054] In addition, the LTE-M network can also ensure the reliability of narrowband communication to a certain extent. In the case of metal obstruction and electromagnetic interference in the garage, by optimizing the LTE-M network parameters, such as enhancing the signal repetition transmission mechanism and adjusting the modulation and demodulation method, it can ensure that the transmission rate of detection data packets, including radio frequency hardware self-test data, analog interactive detection data and VoLTE voice detection data, is greater than or equal to 99.9%, and the latency is less than or equal to 1 second, thus realizing a more reliable and stable locomotive radio entry and exit detection scheme.

[0055] Based on the above embodiments, as an optional embodiment, the application interaction panel is further used to transmit the network device configuration parameters input by the operation and maintenance personnel to the inbound and outbound detection server in response to the batch configuration input by the operation and maintenance personnel. The inbound / outbound detection server is further configured to generate batch configuration instructions based on the network device configuration parameters, and send the batch configuration instructions to each of the detection terminal devices via the LTE-M network; The detection terminal device is also used to update the local configuration in batches in response to the batch configuration command.

[0056] Network device configuration parameters are a set of core parameters used to configure, manage, and identify the operating status of network devices, covering multiple dimensions such as device network connection attributes, security authentication information, service operation parameters, and device ledger information.

[0057] The network device configuration parameters include, but are not limited to, at least one of the following: management configuration parameters, dispatch commands, and locomotive radio logbook. The management configuration parameters include, but are not limited to, at least one of the following: local IP, cluster IP, board IP, control port, transparent transmission port, cluster port, username, password, dispatch IP, dispatch port, LAN port IP, connected board IP, subnet mask, depot inspection port IP, volume, and PLMN settings. The dispatch commands include, but are not limited to, at least one of the following: dispatch command name, dispatch command number, sender's name, issuing location number, text, train number, locomotive number, and release time. The locomotive radio logbook includes, but is not limited to, at least one of the following: locomotive type, number, IP address, telephone number, manufacturer, location, LTE-M communication unit, control unit, satellite positioning unit, recording unit, TAX box encoder, and MMI terminal number.

[0058] Specifically, in combination Figure 2 As shown, maintenance personnel perform batch configuration input operations for network device configuration parameters in the "Settings Management Module" of the application interaction panel 130 at the application layer. In response to the batch configuration input, the application interaction panel 130 transmits the network device configuration parameters to the inbound / outbound detection server 120 at the platform layer. More specifically, the network device configuration parameters transmitted by the application interaction panel 130 are transmitted via electrical connection to the configuration information sub-server 122 within the inbound / outbound detection server 120. The network device configuration parameters include at least one parameter for configuring one detection terminal device, and may include multiple parameters for configuring multiple different detection terminal devices.

[0059] The configuration information sub-server 122 in the inbound / outbound detection server 120 of the platform layer receives and stores the network device configuration parameters in real time, generates batch configuration instructions corresponding to the detection terminal device 110 according to the network device configuration parameters, and sends the batch configuration instructions to the detection terminal device 110 of the terminal layer through the LTE-M network.

[0060] The detection terminal equipment 110 at the terminal layer, including the locomotive onboard radio 111 and the warehouse inspection equipment 112, receives the batch configuration instruction, executes the batch configuration instruction, performs operations such as adjusting detection parameters and loading ledger information, and completes the update of local configuration.

[0061] Due to limitations in data transmission capabilities, both GSM-R and 450MHz networks require transmitting configuration instructions for each detection terminal device in the locomotive radio entry and exit detection system one by one, resulting in low configuration efficiency and susceptibility to interference during instruction transmission.

[0062] The locomotive radio entry and exit detection system provided by this invention utilizes the high-speed real-time data transmission capability of the LTE-E network to support remote batch parameter and ledger configuration. This allows for the configuration of parameter information for multiple locomotive radios at once through the platform, with data transmission latency less than or equal to 1 second. This enables efficient management and configuration of locomotive radio entry and exit detection solutions for multiple detection terminal devices within the system.

[0063] Based on the above embodiments, as an optional embodiment, the detection terminal device is further configured to collect service connection status data and send the service connection status data to the inbound / outbound detection server through the primary or backup link of the LTE-M network. The inbound / outbound detection server is used to trigger a local alarm when the inbound / outbound detection connection service is determined to be abnormal based on the analysis results of the service connection status data. The application interaction panel is also used to display the local alarm status in real time.

[0064] Service connection status data is a digital mapping data that reflects the health status of the connection between each component of the terminal layer and the service / device; service connection status data includes, but is not limited to, at least one of network interface status data, cluster service status data and vehicle terminal connection status data; service connection status data may specifically include status monitoring data of indicators such as signal strength and link quality.

[0065] Network interface status data reflects the connection status of the network interface between the locomotive-mounted radio and the ground core network, which can be specifically fed back by the interface gateway of the locomotive-mounted radio. For example, if the locomotive-mounted radio is an EV751 radio, the network interface status is the EV751 connection status fed back by the EV751 interface gateway.

[0066] Cluster service status data refers to the status of whether the service is being provided normally, as reported by the cluster service terminal when the detection service terminal includes the cluster service terminal.

[0067] The vehicle-mounted terminal connection status data is the connection status between the locomotive-mounted radio in the detection service terminal and the depot inspection equipment, which can be fed back by the depot inspection equipment.

[0068] Specifically, in combination Figure 2As shown, the locomotive radio 111 in the detection terminal device 110 monitors and collects the network interface status data in the service connection status data in real time, the depot inspection device 112 monitors and collects the vehicle terminal connection status data in the service connection status data in real time, and the trunking service terminal 113 monitors and collects the trunking service status data in the service connection status data in real time. At this time, the network interface status data, the vehicle terminal connection status data, and the trunking service status data together constitute the service connection status data.

[0069] For the locomotive-mounted radio 111, if the network interface connection status is determined to be normal based on the network interface status data, the network interface status data is sent to the platform-layer inbound / outbound detection server 120 via the primary link of the LTE-M network. If the network interface connection status is determined to be abnormal, the data is switched to the backup link of the LTE-M network to send the network interface status data to the platform-layer inbound / outbound detection server 120. For example, if the network interface connection status is abnormal, it indicates that the primary link based on the 751 interface of the locomotive-mounted radio 111 is disconnected. In this case, the system automatically switches to the backup LTE-M link for direct connection, ensuring uninterrupted detection.

[0070] For the inspection equipment 112, regardless of whether the onboard terminal connection status is normal or abnormal based on the onboard terminal connection status data, the onboard terminal connection status data is sent to the inbound / outbound detection server 120 at the platform layer via the primary link of the LTE-M network. However, when the onboard terminal connection status is abnormal, it indicates that the primary link between the inspection equipment 112 and the locomotive radio 111 based on the 751 interface is disconnected. At this time, the backup link in the LTE-M network is activated to transmit data between the locomotive radio 111 and the inspection equipment 112.

[0071] For the cluster service terminal 113, if the cluster service status is determined to be normal based on the cluster service status data, the cluster service status data is sent to the inbound / outbound detection server 120 at the platform layer through the primary link of the LTE-M network. If the cluster service status is determined to be abnormal, the cluster service status data is switched to the backup link of the LTE-M network to send the cluster service status data to the inbound / outbound detection server 120 at the platform layer.

[0072] More specifically, the service connection status data is sent to the status management sub-server 123 of the inbound / outbound detection server 120 via either the primary link or the backup link of the LTE-M network.

[0073] The status management sub-server 123 of the inbound / outbound detection server 120 at the platform layer receives service connection status data in real time and analyzes the data to obtain analysis results. If the analysis results determine that the inbound / outbound detection connection service is abnormal (e.g., connection timeout 751, connection disconnection abnormality, etc.), a local alarm is triggered on the inbound / outbound detection server.

[0074] Finally, after the service connection status data transmission is complete, the service status monitoring module 301 in the application interaction panel 130 of the terminal layer displays the local alarm status based on the local alarms being triggered, in order to remind maintenance personnel to resolve service connection status anomalies as soon as possible. For example, a solid green status indicator light is used to indicate a normal alarm-free state, while a flashing red status indicator light is used to indicate an abnormal local alarm state.

[0075] Optionally, the application interaction panel is also used to receive historical status retrospective query operations from operation and maintenance personnel after displaying the local alarm status in real time, and then pull service connection status data for a specified historical period from the inbound and outbound detection server 120, and display the service connection status data for the specified historical period, thereby supporting historical status retrospective query and alarm status detail query.

[0076] GSM-R and 450MHz networks do not have native status monitoring capabilities. If inbound / outbound detection is required, additional monitoring equipment needs to be deployed, resulting in a response delay of 30 seconds or more.

[0077] The locomotive radio entry and exit detection system provided by this invention utilizes the native status monitoring capabilities of the LTE-M network to monitor the connection status of network interfaces, trunking services, and inspection equipment in real time, enabling multi-service connection status linkage. It can also trigger backup link switching through service connection status data to ensure uninterrupted locomotive radio entry and exit detection.

[0078] In addition, based on the native state monitoring capabilities of the LTE-M network, it can quickly detect connection loss through a heartbeat packet mechanism with an interval of less than or equal to 10 seconds, thereby quickly triggering backup link switching.

[0079] Based on the above embodiments, as an optional embodiment, the service connection status data includes network interface status data, cluster service status data, and vehicle terminal connection status data; The analysis results based on the service connection status data determine the abnormality of the inbound / outbound detection connection service, including: If any of the analysis results of the network interface status data, the cluster service status data, and the vehicle terminal connection status data are abnormal, the inbound / outbound detection connection service is determined to be abnormal.

[0080] Specifically, the status management sub-server of the platform-layer inbound / outbound detection server receives service connection status data in real time. It then analyzes the network interface status data, cluster service status data, and vehicle terminal connection status data to obtain three analysis results. If any of these three results is abnormal, the inbound / outbound detection connection service is deemed abnormal, triggering a local alarm to alert maintenance personnel to resolve the issue as soon as possible. Only if all three analysis results are normal is the inbound / outbound detection connection service considered normal.

[0081] The locomotive radio entry and exit detection system provided by this invention can improve the monitoring sensitivity of service connection status and thus improve the reliability of locomotive radio entry and exit detection by triggering a local alarm state when any of the three analysis results of network interface status data, cluster service status data and vehicle terminal connection status data are abnormal.

[0082] Based on the above embodiments, as an optional embodiment, sending the service connection status data to the inbound / outbound detection server via the primary or backup link of the LTE-M network includes: If, based on the analysis results of the service connection status data, it is determined that the inbound / outbound detection connection service is abnormal, the service connection status data will be sent to the inbound / outbound detection server via the backup link of the LTE-M network; or, after a preset retry waiting time, the service connection status data will be sent to the inbound / outbound detection server via the primary link of the LTE-M network.

[0083] Specifically, after the detection terminal device collects service connection status data, it analyzes the data locally to obtain analysis results. If, based on the analysis results, it is determined that the inbound / outbound detection service between the terminal-layer detection terminal device and the platform-layer inbound / outbound detection server is abnormal due to network issues, i.e., the primary link is temporarily unavailable, then a switch to the backup link can be initiated, and the service connection status data can be sent to the inbound / outbound detection server via the backup link of the LTE-M network.

[0084] Alternatively, a preset retry waiting time (such as 30 seconds or 1 minute) can be waited for the LTE-M network's own network repair capabilities to fix the faults in the primary link. After the preset retry waiting time, the service connection status data can be sent to the inbound / outbound detection server again through the LTE-M network's primary link. For example, if the LTE-M network's primary link is temporarily interrupted, the locomotive's onboard radio will locally buffer 100 unsent RF hardware self-test data entries and automatically retransmit the unsent RF hardware self-test data to the detection data sub-server after the preset retry waiting time and the restoration of the LTE-M network's primary link.

[0085] The locomotive radio entry and exit detection system provided by this invention utilizes the native state monitoring and fault-tolerant design capabilities of the LTE-M network. When an anomaly is detected in the service network connection status, data transmission is performed by switching to a backup link or by retrying after waiting for a preset retry time. This efficient fault-tolerant mechanism ensures data integrity and guarantees uninterrupted locomotive radio entry and exit detection.

[0086] Based on the above embodiments, as an optional embodiment, sending the detection data packet through the LTE-M network includes: The detection data packet is sent to the LTE-M base station of the LTE-M network, and the LTE-M base station verifies whether the detection terminal device belongs to the base station authorized device based on the detection data packet; If the detection terminal device is verified to be an authorized device of the base station, the detection data packet is sent to the LTE-M operator server of the LTE-M network, and the LTE-M operator server verifies whether the detection terminal device is an authorized device of the operator based on the detection data packet. If the detection terminal device is verified to be an operator-authorized device, the detection data packet is sent to the inbound / outbound detection server; The step of generating a locomotive radio entry / exit detection report based on the detected data packet includes: Based on the detection data packet, verify whether the detection terminal device belongs to the target detection device; If the detection terminal device is verified to be the target detection device, the detection data packet is parsed and analyzed to generate a locomotive radio entry and exit detection report.

[0087] Among them, the base station authorized equipment is the detection terminal equipment that is pre-authorized by the LTE-M base station in the area where the detection terminal equipment is located and is allowed to access the LTE-M network of the LTE-M base station; the operator authorized equipment is the detection terminal equipment that is pre-authorized by the operator of the detection terminal equipment and is allowed to access the LTE-M network of the operator; and the target detection equipment is the detection terminal equipment that needs to be detected in the current locomotive radio entry and exit detection.

[0088] Understandably, the detection data packet includes not only the radio frequency hardware self-test data collected by the locomotive's onboard radio, the analog interactive test data collected by the inspection equipment, or the VoLTE voice test data collected by the inspection equipment, but also the necessary verification data used to verify whether the corresponding detection terminal equipment belongs to the base station authorized equipment, operator authorized equipment, and target detection equipment. This necessary verification data includes, but is not limited to, digital certificates, International Mobile Subscriber Identity (IMSI), Public Land Mobile Network ID (PLMN ID), and equipment identification codes.

[0089] Specifically, during the process of the detection terminal device sending the detection data packet to the inbound / outbound detection server of the platform layer through the LTE-M network, the detection data packet is first sent to the LTE-M base station in the area where the detection terminal device is located in the LTE-M network. The LTE-M base station then verifies whether the detection terminal device is an authorized device of the base station based on the necessary verification data in the detection data packet.

[0090] If the verification and testing terminal device is not an authorized device of the base station, the LTE-M base station will not send the detection data packet to the operator. If the verification and testing terminal device is an authorized device of the base station, the LTE-M base station will send the detection data packet to the LTE-M operator server of the LTE-M network. The LTE-M operator server will then verify whether the detection terminal device is an authorized device of the operator based on the necessary verification data in the detection data packet.

[0091] If the verification and testing terminal device is not an authorized device of the operator, the LTE-M operator server will not send the detection data packet to the inbound / outbound detection server. Only if the verification and testing terminal device is an authorized device of the operator will the LTE-M operator server send the detection data packet to the inbound / outbound detection server. After receiving the detection data packet, the detection data sub-server of the inbound / outbound detection server verifies whether the detection terminal device belongs to the target detection device based on the necessary verification data in the detection data packet.

[0092] If the verification and testing terminal device is not the target testing device, the inbound / outbound testing server will not generate a locomotive radio inbound / outbound testing report based on the original testing data in the testing data packet. Only when the verification and testing terminal device is the target testing device will the inbound / outbound testing server parse and analyze the testing data packet and generate a locomotive radio inbound / outbound testing report based on the original testing data in the testing data packet.

[0093] The locomotive radio entry and exit detection system provided by this invention establishes a multi-factor authentication mechanism of "base station - operator - entry and exit detection server" during the transmission of detection data packets based on the LTE-M network. This prevents unauthorized devices, such as those that forge locomotive terminals to send false detection results, from accessing the entry and exit detection system, thus ensuring system access security.

[0094] Based on the above embodiments, as an optional embodiment, the detection data packet further includes a digital certificate, an authorized user code, and a device identity code; The step of verifying whether the detection terminal device belongs to the base station authorized device based on the detection data packet includes: verifying whether the detection terminal device belongs to the base station authorized device based on the digital certificate; the digital certificate is pre-distributed to the detection terminal device by the LTE-M base station; The step of verifying whether the detection terminal device belongs to the operator-authorized device based on the detection data packet includes: verifying whether the detection terminal device belongs to the operator-authorized device based on the authorized user code; the authorized user code is pre-configured for the detection terminal device by the LTE-M operator server; The step of verifying whether the detection terminal device belongs to the target detection device based on the detection data packet includes: verifying whether the detection terminal device belongs to the target detection device based on the device identification code.

[0095] Among them, the digital certificate is a core security credential pre-distributed to the testing terminal device by the LTE-M base station in the region where the testing terminal device is located; the authorized user code is a string or code pre-configured by the LTE-M operator server to which the testing terminal device belongs, used to uniquely identify the authorized identity of the device operator, specifically it can be the IMSI code on the USIM card installed in the testing terminal device; the device identity code is a unique identity code determined by the inbound / outbound testing server for the testing terminal device.

[0096] Understandably, the detection data packet includes raw detection data, digital certificate, authorized user code, and device identity code.

[0097] Specifically, this embodiment employs a more detailed USIM card authentication and device unique ID authorization mechanism based on the LTE-M network. The detection data packet includes a digital certificate, an authorized user code, and a device identity code. After receiving the detection data packet, the LTE-M base station determines whether the digital certificate in the detection data packet is a digital certificate pre-distributed to the corresponding detection terminal device by the LTE-M base station. If the two match, it indicates that the detection terminal device belongs to the base station's authorized device, and the detection data packet is forwarded to the LTE-M operator server.

[0098] After receiving the detection data packet, the LTE-M operator server determines whether the authorized user code in the detection data packet is the authorized user code pre-configured by the LTE-M operator server for the detection terminal device, such as whether the IMSI code is consistent. If the two are consistent, it means that the detection terminal device belongs to the operator's authorized device. At this time, the USIM card authentication based on the LTE-M network is completed, and the detection data packet is forwarded to the inbound and outbound detection server.

[0099] After receiving the detection data packet, the inbound / outbound detection server determines whether the device identification code in the detection data packet is the same as the unique identification code corresponding to each target detection terminal to be detected in the current time. If so, it means that the detection terminal device belongs to the target detection device of the current inbound / outbound detection. The inbound / outbound detection server then generates a locomotive radio inbound / outbound detection report based on the detection data packets sent by the target detection devices.

[0100] The locomotive radio entry / exit detection system provided by this invention establishes a USIM card authentication and device unique ID authorization mechanism based on the LTE-M network during the transmission of detection data packets. The LTE-M base station, LTE-M operator server, and entry / exit detection server sequentially verify identity based on the digital certificate, authorized user code, and device identity code within the same detection data packet. Only after successful triple verification will the entry / exit detection server generate a detection report based on the original detection data in the detection data packet. This prevents unauthorized devices, such as those forging locomotive terminals to send false detection results, from accessing the entry / exit detection system, ensuring system access security and the accuracy of the generated detection report.

[0101] Based on the above embodiments, as an optional embodiment, determining the detection data packet based on the original detection data includes: The original detection data is encrypted using the national cryptographic algorithm to obtain the detection data packet.

[0102] Optionally, the national cryptographic algorithm is the SM4 algorithm.

[0103] Specifically, after the detection terminal equipment collects the raw detection data, it uses the national cryptographic algorithm to encrypt the raw detection data to obtain encrypted detection data packets, and then transmits the detection data packets to the inbound and outbound detection server through the LTE-M network.

[0104] Optionally, determining the detection data packet based on the original detection data includes: encrypting the original detection data, digital certificate, authorized user code, and device identity code using a national cryptographic algorithm to obtain the detection data packet.

[0105] The locomotive radio entry and exit detection system provided by the present invention encrypts the monitoring data sent by the detection terminal equipment to the entry and exit detection server at the platform layer using the national cryptographic algorithm before transmission, which can prevent the detection data from being tampered with or stolen.

[0106] Based on the above embodiments, as an optional embodiment, determining the detection data packet based on the original detection data includes: Based on the original detection data, redundant detection data are determined; The detection data packet is determined based on the original detection data and the redundant detection data.

[0107] Optionally, the redundancy detection data is a Cyclic Redundancy Check (CRC).

[0108] Specifically, after the detection terminal device collects the original detection data, it first determines the redundant detection data corresponding to the original detection data, such as the CRC code, and then combines the original detection data and the redundant detection data to obtain the detection data packet to be sent.

[0109] The locomotive radio entry and exit detection system provided by this invention employs information redundancy technology in the detection of locomotive radio entry and exit, adding redundant information to the detection data. This helps to detect and correct errors in the data during transmission and storage, achieving accurate and efficient locomotive radio entry and exit detection.

[0110] In another embodiment, determining the detection data packet based on the original detection data and the redundant detection data includes: determining the detection data to be sent based on the original detection data and the redundant detection data; encrypting the detection data to be sent using a national cryptographic algorithm to obtain the detection data packet.

[0111] Optionally, the national cryptographic algorithm is the SM4 algorithm.

[0112] Based on the above embodiments, as an optional embodiment, generating batch configuration instructions based on the network device configuration parameters includes: Based on the network device configuration parameters, generate unencrypted batch configuration instructions; The unencrypted batch configuration command is encrypted using the national cryptographic algorithm to obtain the batch configuration command.

[0113] Optionally, the national cryptographic algorithm is the SM4 algorithm.

[0114] Specifically, after receiving the network device configuration parameters transmitted from the application interaction panel, the inbound / outbound detection server first generates unencrypted batch configuration commands based on the network device configuration parameters. Then, it further encrypts the unencrypted batch configuration commands according to the national cryptographic algorithm to obtain encrypted batch configuration commands, which are then sent to the corresponding detection terminal devices.

[0115] The locomotive radio entry and exit detection system provided by this invention generates unencrypted batch configuration commands using network device configuration parameters transmitted through the application interaction panel, and then encrypts the unencrypted batch configuration commands using a national cryptographic algorithm. The encrypted batch configuration commands are then transmitted to the detection terminal device. The encryption protocol ensures the security of the scheduling commands and prevents the batch configuration commands from being tampered with or stolen.
