In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] This application proposes a host unit for a rail transit vehicle-mounted integrated sensing system, used to integrate a CCTV monitoring system, a passenger counting system, and a train operation status monitoring system, such as... Figures 1 to 3As shown, the system includes: a housing 110, a top cover 120, a PC processing board 210, a data adapter board 220, an MVB processing board 310, a power module 410, and a communication module 420. The housing 110 has an opening at its top, and the top cover 120 is positioned at the opening. The housing 110 has multiple insertion holes 101, located on the side adjacent to the opening. The PC processing board 210 is horizontally disposed within the cavity of the housing 110. The PC processing board 210 has an HDMI-PC board 231, a first M12-PC board 232, and a second M12-PC board 233. The HDMI-PC board 231, the first M12-PC board 232, and the second M12-PC board 233 are respectively located at their corresponding insertion holes 101. The HDMI-PC board 231, the first M12-PC board 232, and the second M12-PC board 233 are disposed on the same side and are all adjacent to the opening. The data input terminal of the PC processing board 210 is electrically connected; the data adapter board 220 is disposed on the side of the PC processing board 210 away from the port, and the data adapter board 220 is electrically connected to the PC processing board 210; the MVB processing board 310 is horizontally disposed in the cavity of the housing 110 and is disposed adjacent to the PC processing board 210. The PC processing board 210 is electrically connected to the MVB processing board 310 through the signal conversion board 320. The MVB processing board 310 is suitable for electrically connecting to the train control and management system; the power module 410 is disposed on the side of the PC processing board 210 away from the data adapter board 220. The output terminal of the power module 410 is connected to the power terminal of the PC processing board 210 and the power terminal of the MVB processing board 310, respectively; the communication module is disposed inside the housing 110 and located between the PC processing board 210 and the MVB processing board 310. The communication module 420 is electrically connected to the PC processing board 210.

[0024] It should be noted that the housing 110 serves as the mounting base for the overall structure. The opening at the top of the housing 110 facilitates the installation and maintenance of internal components. The top cover 120 is detachably mounted on the opening of the housing 110 using screws. The housing 110 and the top cover 120 together form a closed chamber, preventing damage to internal components from external dust and moisture, thus ensuring the normal operation of the equipment. The HDMI-PC board 231, the first M12-PC board 232, and the second M12-PC board 233 are integrated on the PC processing board 210, allowing the PC processing board 210 to connect to multiple systems simultaneously, reducing redundant configuration of the system host and saving vehicle space. The connector holes 101 correspond one-to-one with the HDMI-PC board 231, the first M12-PC board 232, and the second M12-PC board 233 on the PC processing board 210. External interfaces can be directly connected via the plug-in hole 101, simplifying the connection process for external systems. The HDMI-PC board 231 is suitable for connecting to a CCTV monitoring system to ensure high-quality video image data access. The first M12-PC board 232 is suitable for connecting to a passenger counting system to receive passenger counting data from different devices such as infrared sensors and pressure sensors. The second M12-PC board 233 is suitable for connecting to a train operation status monitoring system to receive operating parameter data such as train speed, vibration, and temperature collected by various sensors. The HDMI-PC board 231, the first M12-PC board 232, and the second M12-PC board 233 are concentrated on the same side of the PC processing board 210 and are set corresponding to the plug-in hole 101 of the housing 110. The cables of the external system can be connected from the same side of the housing 110, avoiding the layout chaos caused by the cables tangling from multiple sides, shortening the fault handling time, and reducing maintenance costs.

[0025] PC processing board 210 receives video image data from CCTV, passenger flow data from the passenger counting system, and parameter data from the train operation status monitoring system. It also interacts bidirectionally with the MVB processing board via signal conversion board 320. Simultaneously, it receives multi-protocol vehicle basic data transmitted from the train control and management system. PC processing board 210 first converts the multi-protocol vehicle basic data transmitted from the train control and management system into a single internal communication protocol and packages it. PC processing board 210 then analyzes and processes the multi-protocol vehicle basic data based on the unified protocol. Specifically: PC processing board 210 integrates multi-protocol vehicle basic data transmitted by the train control and management system to obtain real-time vehicle positioning information. It uses this vehicle positioning information to add timestamps to the received data for synchronization, ensuring a one-to-one correspondence between CCTV video frames, passenger flow counting results, and operational status parameters in the time dimension. When the passenger counting system detects a sudden increase in passenger flow in a carriage, PC processing board 210 retrieves the CCTV video image data of that carriage from the same period to verify the accuracy of the passenger flow data. Conversely, when CCTV video image data identifies "passenger congestion at the doors," PC processing board 210 retrieves passenger flow data for analysis and comparison. It can also... Passenger flow counting data is correlated with train operation status parameters to subsequently determine potential risks such as whether passenger congestion leads to abnormal train load. The PC processing board 210 transmits the analyzed and processed data to the data conversion board 220. The data conversion board 220 performs format conversion and protocol integration on these data based on data interaction standards to form standardized data, which is then fed back to the PC processing board 210. The PC processing board 210 receives the standardized data fed back by the data conversion board 220, converts it into MVB protocol through the signal conversion board 320, and then transmits it to the train control and management system through the MVB processing board 310 to support operation control and scheduling.

[0026] Among them, the data interaction standard is the existing technology in the relevant field. Specifically, the data interaction standard refers to: defining a differentiated standardized rule system for the characteristics of multi-source data such as video image data, passenger flow data, and equipment parameter data, including but not limited to: data format conversion rules, transmission protocol adaptation, etc.; the signal conversion board 320 is suitable for converting the standardized data of the PC processing board 210 into the MVB protocol that can be recognized by the train control and management system, or converting the train instructions received by the MVB processing board into a protocol that can be recognized by the PC processing board. The MVB processing board 310 is suitable for transmitting the standardized data of the PC processing board 210 to the train control and management system, and at the same time receiving the instructions of the train control and management system, realizing bidirectional data interaction between the PC processing board 210 and the train control and management system.

[0027] The power module 410 provides the necessary stable voltage to the overall system host; the communication module uploads the data received by the PC processing board 210 to the cloud server 600. The communication module 420 uploads the processed data to the cloud server 600 for storage. Staff can access the cloud platform to view information such as the train carriage status and passenger flow density in real time, while avoiding data loss due to equipment failure and providing a reliable basis for tracing safety incidents.

[0028] The CCTV monitoring system's cable is plugged into the HDMI-PC board 231, transmitting the real-time video image data captured by the camera to the PC processing board 210. The passenger counting system's cable is plugged into the first M12-PC board 232, transmitting the counted passenger data to the PC processing board 210. The train operation status monitoring system's cable is plugged into the second M12-PC board 233, transmitting the operating parameter data collected by the sensors to the PC processing board 210. The data conversion board 220 converts the format and integrates the protocol of the data received by the PC processing board 210 and feeds it back to the PC processing board 210. The PC processing board 210 processes and analyzes the integrated and converted data to form standardized data, which is then transmitted to the MVB processing board 310 through the signal conversion board 320. The MVB processing board 310 transmits the data to the train control and management system and transmits the received instructions and information from the train control and management system back to the PC processing board 210, thus completing the data interaction between the system host and the train control and management system.

[0029] This application integrates a CCTV monitoring system, a passenger counting system, and a train operation status monitoring system into a single system host. This integrated system host replaces the original independent host for each of the three systems, reducing redundant configurations, saving onboard space, and lowering the number and cost of system host purchases. Furthermore, by setting up a data adapter board 220 to convert the data format received by the PC processing board 210 and integrate the data transmission protocols, real-time sharing of video image data collected by the CCTV monitoring system, passenger flow data from the passenger counting system, and data collected by the train operation status monitoring system is achieved. Through comprehensive analysis of multi-dimensional data, staff can obtain more comprehensive and in-depth information, avoiding data silos between systems and improving operational management efficiency. Moreover, this application makes full use of the internal space of the housing 110. The PC processing board 210, MVB processing board 310, and data adapter board 220 are arranged closely and orderly within the housing 110, ensuring effective collaboration between components while avoiding space waste and improving the internal space utilization rate of the housing 110.

[0030] Furthermore, it also includes a USB board 234, which is integrated on the PC processing board 210 and is arranged adjacent to the HDMI-PC board 231. The USB board 234 is suitable for connecting external debugging equipment, so that staff can access the operating system or control program of the PC processing board 210 through external devices, and perform operations such as viewing system operation logs, modifying configuration parameters, and running diagnostic tools to detect hardware modules in real time.

[0031] In one possible implementation, the PC processing board 210 adopts the existing model: RDKS100P processing board; the MVB processing board 310 adopts the existing model: D016-SHSZ-MVBCOM-100AB processing board; the data adapter board 220 adopts the existing model: EC200UCNLA-SR900A data adapter board; and the signal conversion board 320 adopts the existing model: MOXACP-102U signal conversion board.

[0032] In one possible implementation, a cooling fan 510 is also included; the cooling fan 510 is disposed on the PC processing board 210 and adjacent to the power module 410, and the PC processing board 210 is electrically connected to the input terminal of the cooling fan 510; the cooling fan 510 is suitable for providing active cooling for the PC processing board 210. The heat generated by the PC processing board 210 during operation will be conducted to the surface through the PCB board. After the cooling fan 510 is started, it will form a directional airflow to directly remove the heat from the surface of the PC processing board 210, thereby improving the heat dissipation efficiency.

[0033] Furthermore, the PC processing board 210 integrates a control chip and a temperature sensor. The temperature sensor is electrically connected to the control chip, and the input terminal of the cooling fan 510 is electrically connected to the control chip. The temperature sensor is suitable for real-time acquisition of the surface temperature of the PC processing board 210, so that the PC processing board 210 can control the speed of the cooling fan 510 based on the acquired real-time temperature. The integration of the control chip and temperature sensor on the PC processing board 210 to control the speed of the cooling fan 510 is a current technological approach. Specifically: When the temperature collected by the temperature sensor is lower than the preset threshold, the control chip outputs a lower control voltage to make the cooling fan 510 run at a lower speed to maintain basic heat dissipation requirements. When the temperature collected by the temperature sensor exceeds the preset threshold, the control chip outputs a higher control voltage to make the cooling fan 510 run faster, increase airflow, and quickly remove heat from the PC processing board 210. The PC processing board 210 uses the temperature sensor to control the power supply of the cooling fan 510, reducing the ineffective operation of the cooling fan 510 and extending its service life.

[0034] Furthermore, the preset threshold value range is 30℃—45℃.

[0035] In one possible implementation, a thermally conductive connector is also included; the thermally conductive connector is filled between the PC processing board 210 and the cooling fan 510; the thermally conductive connector is tightly fitted to the surfaces of the cooling fan 510 and the PC processing board 210 facing each other, which greatly increases the effective contact area for heat conduction, allowing the heat on the surface of the PC processing board 210 to be quickly transferred to the cooling fan 510, further improving the heat dissipation efficiency.

[0036] In one possible implementation, the thermally conductive connector is thermally conductive silicone.

[0037] In one possible implementation, the side wall of the housing 110 is provided with heat dissipation holes 111; the heat dissipation holes 111 are arranged opposite to each other on both sides of the housing 110; it should be noted that the heat dissipation holes 111 are arranged on the side wall of the housing 110 and adjacent to the insertion hole 101. The design of the heat dissipation holes 111 increases the contact area between the housing 110 and the outside air, so that heat can be transferred from the inside of the housing 110 to the outside environment more quickly; effectively reducing the internal temperature of the housing 110 and improving the heat dissipation efficiency.

[0038] Furthermore, there are two or more heat dissipation holes 111, which are arranged in an array along the width of the housing 110.

[0039] In one possible implementation, a mounting bracket 520 is also included; the mounting bracket 520 is disposed opposite to each other on both sides of the housing 110. It should be noted that the mounting bracket 520 and the heat dissipation hole 111 are located on the same side of the housing 110. The mounting bracket 520 is used to firmly fix the housing 110 in the installation position to prevent the system host from loosening, shifting or even falling due to vibration; the main body of the mounting bracket 520 has an L-shaped structure, and the opening of the mounting bracket 520 faces the side away from the housing 110. The side of the mounting bracket 520 adjacent to the heat dissipation hole 111 is fixedly connected to the housing 110, and the other side of the mounting bracket 520 is used to install the housing 110 in the installation position.

[0040] In one possible implementation, such as Figure 2 As shown, the power module 410 includes a converter 412 and a connector 411. The input end of the connector 411 is suitable for electrically connecting to an external power source, and the output end of the connector 411 is electrically connected to the input end of the converter 412. The connector 411 is suitable for transmitting 110V voltage to the converter 412. The output end of the converter 412 is connected to the power supply end of the PC processing board 210 and the power supply end of the MVB processing board 310, respectively. The converter 412 is suitable for converting the 110V voltage into 12V voltage and transmitting it to the PC processing board 210 and the MVB processing board 310, thereby realizing the power supply for the overall system host.

[0041] In one possible implementation, the communication module 420 is for 4 / 5G network communication or cloud communication.

[0042] In one possible implementation, both the housing 110 and the top cover 120 are made of aluminum alloy, thereby effectively shielding electromagnetic interference signals in the vehicle environment and ensuring the accuracy of data processing for the CCTV monitoring system, passenger counting system, and train operation status monitoring system.

[0043] In one possible implementation, the main body of the top cover 120 has an L-shaped structure, and the opening of the top cover 120 is disposed facing the housing 110; the top cover 120 is mounted on the opening of the housing 110, and the top cover 120 is fixedly connected to the side wall of the housing 110.

[0044] It should be noted here that, as Figure 1 , Figure 3 As shown, the top cover 120 includes a first side plate 1201 and a second side plate 1202 that are perpendicular to each other. The outline of the first side plate 1201 is adapted to the top opening of the housing 110. The top cover 120 is mounted on the top opening of the housing 110 through the first side plate 1201 to form a sealing structure, thereby preventing external dust, moisture and other substances from entering the interior of the housing 110 through the top opening. The second side plate 1202 is tightly fitted to the outer wall of the housing 110, and the second side plate 1202 is arranged opposite to the insertion hole 101. The second side plate 1202 is fixedly connected to the side wall of the housing 110 by screws.

[0045] In one possible implementation, a snap-fit ​​member 121 is provided on one side of the top cover 120; a limiting part 102 is provided at the opening of the housing 110, and the snap-fit ​​member 121 extends into the cavity of the housing 110 and abuts against the limiting part 102.

[0046] It should be noted that the top of the side wall of the housing 110 with the insertion hole 101 is provided with a limiting part 102. A snap-fit ​​member 121 is provided on the side of the first side plate 1201 of the upper cover 120 away from the second side plate 1202. When the first side plate 1201 of the upper cover 120 abuts against the limiting part 102, the snap-fit ​​member 121 extends into the cavity of the housing 110 and abuts against the side wall of the housing 110 facing the limiting part 102. The second side plate 1202 is tightly fitted to the side wall of the housing 110. The limiting part 102 and the first side plate 1201... The contact between the snap-fit ​​component 121 and the side wall of the limiting part 102 achieves the initial fixation and limiting of the upper cover 120 at the bayonet of the housing 110. This allows the upper cover 120 to be quickly and accurately aligned with the installation position, facilitating subsequent screw tightening and significantly improving assembly efficiency. The tight contact between the snap-fit ​​component 121 and the side wall of the limiting part 102 creates a mechanical interlock between the two, which can effectively resist and buffer the vibrations and impacts generated in all directions during train operation, preventing relative displacement or shaking between the upper cover 120 and the housing 110.

[0047] In one possible implementation, a riveting post 112 is also included; the riveting post 112 is vertically disposed within the cavity of the housing 110, and the PC processing board 210 is disposed on top of the riveting post 112.

[0048] It should be noted that the riveting posts 112 provide robust mechanical support for the PC processing board 210. The riveting posts 112 are fixed to the bottom of the housing 110 by riveting or welding. Multiple riveting posts 112 are provided, and their heights are consistent to ensure the levelness of the mounting surface. Correspondingly, the PC processing board 210 has riveting holes. During installation, the PC processing board 210 rests on the riveting posts 112, with the riveting holes of the PC processing board 210 aligned with the riveting posts 112. Screws penetrate the PC processing board. The rivet holes of board 210 are riveted to rivet posts 112, thereby horizontally and firmly fixing PC processing board 210 in the cavity of housing 110. The design of rivet posts 112 creates an air circulation layer between PC processing board 210 and bottom of housing 110, preventing heat from accumulating at the bottom. At the same time, it can work with heat dissipation holes 111 and cooling fan 510 of housing 110 to form a more efficient three-dimensional heat dissipation system, further improving heat dissipation performance. This space can also be used to lay some cables, making the internal layout neater and more compact.
