Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0028] As described in the background section, related vehicle terminals often employ a single communication module (such as a 2G / 3G or independent GPS module), resulting in low data transmission rates and insufficient positioning accuracy. Furthermore, they generally rely on the vehicle's power supply, meaning they cannot continue operating after the vehicle is turned off, leading to the loss of critical data. In addition, existing devices have limited interface types (usually only retaining the OBD interface), making it difficult to meet the needs of debugging, data export, and external device expansion. Under complex operating conditions, they are susceptible to environmental factors such as humidity and vibration, leading to interface oxidation or poor contact. Moreover, the overall integration is low, resulting in scattered functional components, which is detrimental to later maintenance and expansion of requirements.
[0029] To address the issues in the relevant technologies, the following will be discussed in conjunction with... Figures 1-3 This utility model describes a data acquisition and transmission terminal, including a housing 10, a main control module 20, and a power module 300. The housing 10 includes a base 103, an intermediate body 102, and a cover plate 101. The base 103 is connected to the bottom of the intermediate body 102, and the cover plate 101 is connected to the top of the intermediate body 102 to form an installation space inside the intermediate body 102. The main control module 20 is disposed within the installation space and is used to acquire vehicle data and control data transmission. The power module 300 is disposed within the installation space and is electrically connected to the main control module 20. The intermediate body 102 is used to provide power to the main control module 20. The intermediate body 102 has a satellite positioning antenna 40, a communication antenna 30, a data interface 90, a power interface 60, a communication interface 100, and an external charging interface 70 on its circumferential sidewalls. The satellite positioning antenna 40, communication antenna 30, data interface 90, and communication interface 100 are all electrically connected to the main control module 20. The power interface 60 and external charging interface 70 are both electrically connected to the power module 300. The power interface 60 is used to connect an external power source and charge the power module 300, while the external charging interface 70 is used to provide power to external devices. The vehicle-mounted terminal is used for communication, data processing, information collection, and control between the vehicle and external systems. In conventional setups, the terminal is often powered by the vehicle's power supply, which leads to poor stability in some scenarios. Furthermore, the conventional terminal has a single interface, resulting in poor expandability and hindering external debugging and functional expansion. In this embodiment, by integrating multiple interfaces onto the intermediate body 102, the overall setup is facilitated, and subsequent maintenance and expansion debugging are made easier. Furthermore, an independent power supply module 300 is provided within the installation space, which enables independent power supply to the terminal and improves the stability of the terminal.
[0030] Specifically, the housing 10 is made of aluminum alloy. The intermediate body 102 has a rectangular ring structure. The base 103 and the cover plate 101 can seal the bottom and top of the intermediate body 102 respectively, thus forming a relatively sealed installation space, in which the main control module 20 is located. The base 103 has connecting parts protruding from the intermediate body 102 at each of its four corners, and each connecting part includes a connecting hole. The base 103 can be fixed to the outer body by bolts engaging with the connecting holes.
[0031] The satellite positioning antenna 40 receives positioning signals from satellites, ensuring accurate location information, typically with meter-level or even centimeter-level precision. The communication antenna 30 transmits and receives wireless signals, enabling remote monitoring of the terminal system, facilitating debugging, and transmitting remote data. The combined use of the satellite positioning antenna 40 and communication antenna 30 supports high-speed data transmission and high-precision positioning, meeting the remote monitoring needs of construction vehicles. The data interface 90 connects to the vehicle's OBD port (On-Board Diagnostics) to acquire vehicle operating data, enabling real-time data acquisition and transmission.
[0032] Understandably, in some scenarios, such as data from automated construction vehicles and autonomous vehicles, real-time feedback is required, along with ensuring stability during operation and continuous debugging over long periods. In this embodiment, the main control module 20 is detachably connected to the installation space. The main control module 20 can process and transmit the collected data, and a power module 300 is provided within the installation space. The power module 300 can independently power the terminal, ensuring that the terminal's operation is unaffected by external vehicle conditions and improving its stability. Furthermore, the intermediate body 102 is equipped with multiple interfaces. The integrated design of these interfaces facilitates fabrication and enables connection to external devices, allowing for debugging during operation and enhancing the terminal's flexibility.
[0033] In practical applications, the power interface 60 can be connected to an external power source. For example, the power interface 60 can be connected to the main power source of the vehicle, so that power can be supplied through an external power source under normal conditions. However, when there is a problem with the supply of the external power source (such as a sudden cut-off), the power module 300 of this embodiment can supply power independently, thereby improving the overall stability of the terminal.
[0034] During operation, when the vehicle starts, the main control module 20 is activated and can collect data through the vehicle's data acquisition elements. The data is then processed by the main control module 20 and transmitted. The satellite positioning antenna 40 can receive location information in real time, enabling real-time location feedback, while the communication antenna 30 facilitates high-speed data transmission and reduces data transmission latency.
[0035] Specifically, both the satellite positioning antenna 40 and the communication antenna 30 include an "L"-shaped connecting rod, one end of which is connected to the intermediate body 102, and the other end of which is connected to the antenna body.
[0036] like Figure 4 As shown in some embodiments, the power module 300 includes a lithium battery and a voltage converter. The input terminal of the voltage converter is connected to the power interface 60, and the output terminal of the voltage converter is electrically connected to the lithium battery. Externally introduced power often does not match the voltage required by the terminal. In this embodiment, the voltage converter transforms the input power, thereby enabling the input power to match the voltage required by the components.
[0037] Specifically, the lithium battery can store electrical energy and can be charged by the external power source, thus keeping the lithium battery fully charged at all times. This can protect the various components in the internal main control module 20 in the event of a sudden power outage and can also be used as a backup power source in an emergency, improving the stability of the terminal's operation.
[0038] The battery module is also connected to an external charging interface 70. Specifically, the external charging interface 70 is electrically connected to the lithium battery. The external charging interface 70 allows external devices to charge the lithium battery or to reliably assess the real-time status of the lithium battery. For example, by connecting the external charging interface 70 to a battery management system, the charging and discharging of the battery can be evaluated, improving convenience.
[0039] In practical applications, a voltage converter and lithium battery can be built into the power module 300. This allows for automatic power switching when the vehicle battery power is disconnected. The voltage converter converts the vehicle's 12-24V power supply to 5V, while the backup lithium battery uses 5V. Furthermore, when powered independently, the terminal can operate continuously for at least 12 hours.
[0040] In some embodiments, such as Figure 3 As shown, the satellite positioning antenna 40 and the communication antenna 30 are disposed on the same outer side wall of the intermediate body 102, with the satellite positioning antenna 40 located above the communication antenna 30. By disposing of the antennas on the same side wall, it is easier to connect the two antennas quickly and improve the overall integration.
[0041] Specifically, antennas require a certain amount of space. In this embodiment, two antennas are placed on the same side, which reduces the overall space occupied by the housing 10 and reduces the overall volume of the terminal.
[0042] like Figure 3 As shown, the communication interface 100 includes a network interface 1001, a high-definition multimedia interface 1002, and a USB interface 50. The network interface 1001 and the high-definition multimedia interface 1002 are located on the same outer side wall of the intermediate body 102, while the USB interface 50 is located on the side wall opposite to the network interface 1001, and is positioned below the communication antenna 30. During terminal use, multiple lines need to be connected. In this embodiment, the network interface 1001, the high-definition multimedia interface 1002, and the USB interface 50 are distributed on two opposite side walls, which improves the overall integration and reduces the overall space occupation.
[0043] It is understandable that space is limited in a vehicle, and reducing the space occupied by each component or assembly will greatly improve the space utilization of the vehicle. In this embodiment, multiple interfaces are distributed on multiple side walls of the intermediate body 102, which can improve the overall integration and reduce the overall space occupied.
[0044] The satellite positioning antenna 40 and the communication antenna 30 are located on the upper part of one side wall of the intermediate body 102, while the USB interface 50 is located on the lower part. This arrangement allows for sufficient installation spacing between the interfaces without increasing the space occupied by the intermediate body 102.
[0045] In some implementations, the data interface 90 and the power interface 60 are located on the same outer side wall of the intermediate body 102, and the data interface 90 and the power interface 60 are spaced apart. This same-side arrangement facilitates easier connection of data cables or wires between the two interfaces.
[0046] In conjunction with the above embodiments, the data acquisition and transmission terminal also includes an indicator light 80, which is located between the data interface 90 and the power interface 60. By placing the indicator light 80 between the two, the space occupied by each component is reduced, and the integration of the terminal is improved.
[0047] Specifically, both the indicator light 80 and the external charging interface 70 are located between the data interface 90 and the power interface 60, which allows for multiple connection interfaces on the same side wall, improving overall integration. Furthermore, this arrangement enables multiple operation steps to be performed on one side, increasing work efficiency.
[0048] The indicator lights 80 have different colors to display the communication, positioning, and power status. Specifically, the blue indicator light 80 displays the 4G / 5G communication status (solid light indicates normal connection, flashing indicates weak signal); the green indicator light 80 displays the satellite positioning status (solid light indicates successful positioning, off indicates no positioning); and the red indicator light 80 displays the power status (solid light indicates normal power supply, flashing indicates low power).
[0049] In specific configurations, waterproof sealing covers 200 are provided at the locations of the data interface 90, power interface 60, communication interface 100, and USB interface 50. Some interfaces require connection to external wires to achieve different functions. In this embodiment, the waterproof sealing covers 200 prevent external liquids or dust from entering.
[0050] Specifically, such as Figure 2 , Figure 3 As shown, each waterproof sealing cap 200 is hinged to the mounting post, and the mounting post has the aforementioned interface. This allows each mounting post to be sealed by the waterproof sealing cap 200 when not connected, thereby preventing external liquids or dust from entering through the interface and improving the stability and reliability of the terminal operation.
[0051] The external charging interface 70 includes raised metal contacts that enable power transfer. In other words, when an external device needs charging, it connects to the metal contacts to establish electrical conductivity.
[0052] Understandably, by using the waterproof sealing cover 200, the installation space becomes an entirely enclosed space, making its working environment relatively independent, avoiding interference from the external environment, and improving stability.
[0053] According to some embodiments provided by this utility model, the main control module 20 includes a main control board, which is mounted in the installation space via a mounting bracket 202 and is bolted to the mounting bracket 202. The main control board integrates basic components such as a data processor, a data storage device, and a buffer, which can realize the entire process of data acquisition, processing, and transmission.
[0054] Specifically, the processor inside the main control board is an ARM Cortex-A53 processor, with built-in CAN bus and LIN bus protocol parsing firmware, enabling efficient and fast data processing.
[0055] Specifically, the mounting bracket 202 and the base 103 are connected by bolts, and the main control board is mounted on the mounting bracket 202 by bolts. This bolted connection facilitates disassembly and assembly during subsequent maintenance or debugging, reducing maintenance difficulty and increasing flexibility.
[0056] like Figure 3 As shown, in specific configurations, the main control board integrates a heat sink 205, a SIM card slot, a cellular communication module 203, a satellite positioning module 204, and an onboard interface 201. These integrated components enable stable operation of the main control board.
[0057] Specifically, the heat sink 205 increases the contact area with the installation space, thereby enabling rapid heat conduction and dissipation, achieving efficient heat dissipation within the installation space. The SIM card slot and cellular communication module 203 enable remote network connectivity, facilitating remote control. The cellular communication module 203 includes a Quectel EC25 chip, supporting full network compatibility. The satellite positioning module 204 uses a U-Blox NEO-6M chip, supporting GPS / GLONASS dual-mode positioning.
[0058] The onboard interface 201 includes an onboard high-definition media interface 2013, an onboard USB interface 2012, and an onboard RJ45 interface 2011. The onboard interface 201 facilitates the functional debugging of the main control board and enables subsequent functional expansion and debugging. During connection, the 4G / 5G communication antenna 30 and the satellite positioning antenna 40 are independently configured and connected to their respective modules via SMA to IPEX interface cables. For example, the communication antenna 30 is connected to the cellular communication module 203 via an SMA to IPEX interface cable, and the satellite positioning antenna 40 is connected to the satellite positioning module 204 via an SMA to IPEX interface cable. The RJ45 interface is used for firmware burning, log export, and remote SSH debugging; the onboard high-definition media interface 2013 is used to connect an external display to show the terminal's operating status, location map, or debugging command-line interface in real time; and the USB interface 50 is used to connect external storage devices or debugging terminals for offline data backup.
[0059] In some embodiments, a first sealing ring is provided between the cover plate 101 and the intermediate body 102, and a second sealing ring is provided between the base 103 and the intermediate body 102. By providing sealing rings on both sides of the intermediate body 102, the sealing performance inside the installation space is further improved, enabling the waterproof rating to reach IP65.
[0060] Specifically, the sealing ring is a flexible sealing ring, which allows the sealing ring to be squeezed and deformed when the cover plate 101, base 103 and intermediate body 102 are connected, thereby improving the sealing of the installation space, avoiding the influence of the external environment on internal main control components, power module 300 and other components, and improving the stability of the terminal.
[0061] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment forms a housing 10 structure with an installation space through the base 103, intermediate body 102, and cover plate 101. This method facilitates the installation of the housing 10, and the main control module 20 and power module 300 are provided in the installation space, which can independently power the entire terminal, improving the stability of the terminal's operation. Furthermore, the setting of positioning antenna and communication antenna 30 enables the terminal to support high-speed data transmission and high-precision positioning, meeting the remote monitoring needs of construction vehicles. Furthermore, the setting of multiple interfaces enables the terminal to support firmware upgrades, data export, and external device connection, meeting diverse debugging needs.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
