[0002] In the scenario of managing the entry and exit of material vehicles at smart construction sites, the intelligent verification machine is the core equipment for vehicle information verification and business data processing. Its normal operation requires a stable power supply for its internal components and external connected devices. Existing equipment typically uses UPS (Uninterruptible Power Supply) for power, but UPS power supplies can only store basic electrical energy and output a single type of voltage, unable to simultaneously provide multiple DC outputs of different voltage specifications. This makes it completely unsuitable for the multi-voltage power supply needs of the intelligent verification machine and its associated devices. This necessitates the additional configuration of multiple power supply units of different specifications to power internal components / external devices with varying voltage requirements in practical applications. This not only increases equipment deployment costs and space occupation but also easily leads to power instability due to multi-power supply coordination issues, affecting the efficient operation of vehicle entry and exit verification. Therefore, how to enable the power module of the intelligent verification machine to provide multiple DC outputs of different voltage specifications has become a technical problem that urgently needs to be solved by those skilled in the art.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0015] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, 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, article, or apparatus. Without further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0016] Example 1 This utility model provides an intelligent inspection and verification machine for material vehicles entering and leaving the site, such as... Figure 1 As shown, the intelligent verification all-in-one machine specifically includes the following components: a switching power supply and a power board, wherein the power board includes: an AC / DC converter and a power management circuit; The input terminal of the switching power supply is connected to an external 220V AC power supply; the first output terminal of the switching power supply is connected to the input terminal of the AC-DC converter to provide 220V AC power to the AC-DC converter; and the second output terminal of the switching power supply is connected to the first input terminal of the power management circuit to provide 12V DC power for power supply to the power management circuit. The AC / DC converter is used to convert 220V AC power to 12V DC power, and the output terminal of the AC / DC converter is connected to the second input terminal of the power management circuit to provide the power management circuit with 12V DC power for output. The power management circuit has N output terminals for connection to other devices, and the power management circuit is used to convert the 12V DC power for output into N DC power of different voltage specifications for use by the N output terminals; where N is a positive integer greater than or equal to 2.

[0017] In this embodiment, the power module of the smart verification machine has been optimized. Specifically, a 220V AC mains power supply is connected to a switching power supply, providing two outputs. The first output terminal outputs 220V AC power, which is directly connected to the AC / DC converter on the power board to provide the raw power for the AC / DC converter. The second output terminal outputs 12V DC power, which is connected to the power management circuit on the power board to directly provide the basic operating power for the power management circuit. The AC / DC converter is an AC-to-DC converter used to convert 220V AC power into 12V DC power that can be used by the power management circuit. The power management circuit converts the 12V DC power provided by the AC / DC converter to obtain N different voltage specifications of DC power. The power management circuit is provided with N output terminals, which can be connected to the internal components and / or external devices of the smart verification machine respectively and provide DC power of the corresponding specifications.

[0018] Preferred, such as Figure 2 As shown, the N output terminals of the power management circuit include: 7 output terminals providing 12V DC power, 1 output terminal providing 24V DC power, and 1 output terminal providing 53V DC power; The seven 12V DC output terminals are respectively connected to the video server, front panel, industrial computer, communication board, external weighing scale and two external displays. Both the 24V DC output terminal and the 53V DC output terminal are connected to the POE board.

[0019] It should be noted that the video server, front panel, industrial control computer, and communication board are internal components of the intelligent verification all-in-one machine, while the external weighbridge and two external displays are external related devices. In addition, the power management circuit also has a "power supply isolation" function, with each output controlled independently and without interference. When one output fails, it will not affect the power supply of other outputs, thus improving the overall fault tolerance.

[0020] In this embodiment, by combining a switching power supply, an AC / DC converter, and a power management circuit with multiple output terminals, multiple DC power supplies of different voltage specifications can be output, which can directly meet the differentiated power supply needs of the internal devices and external related devices of the smart verification machine without the need to configure multiple additional power supply devices.

[0021] Specifically, such as Figure 2 As shown, the intelligent verification machine also includes: an internal battery and an external battery; The internal battery is connected to the power management circuit and is used to charge the switching power supply through the power management circuit when the switching power supply is connected to an external 220V AC power supply, and to supply power to the power management circuit when the switching power supply is not connected to an external 220V AC power supply. The external battery is connected to the power management circuit and is used to supply power to the power management circuit when the switching power supply is not connected to an external 220V AC power source and the internal battery is depleted.

[0022] In this embodiment, the power module of the smart verification machine also includes an internal battery and an external battery. When the power module is connected to 220V AC mains power, the internal battery can be charged through a 12V DC interface of the power management circuit. When there is no 220V AC mains power (power outage), the power management circuit can be powered by the internal battery. When the internal battery is depleted, it can also be powered by an external battery connected to an external interface of the power management circuit, ensuring that the smart verification machine can operate normally even in the event of a power outage. This embodiment adopts a three-level power supply design of "AC power + internal battery + external battery" to solve the problem of operation interruption caused by power outage.

[0023] In addition, such as Figure 2 As shown, the intelligent verification machine also includes a 220V filter, and the 220V filter has a built-in fuse; The input terminal of the 220V filter is connected to an external 220V AC power supply, and the output terminal of the 220V filter is connected to the input terminal of the switching power supply. The 220V filter is used to filter voltage fluctuations and current interference in the external 220V AC power supply. At the same time, it triggers the fuse to blow when the voltage and / or current is abnormal, so as to realize power failure protection and thus provide stable AC power for the subsequent power supply link.

[0024] Furthermore, such as Figure 2 As shown, the power board also includes: a microcontroller, a memory chip, a temperature sensor, a control switch, and a charging status indicator; The microcontroller is connected to the power management circuit, the memory chip, the temperature sensor, the control switch, and the charging status light, respectively. The microcontroller, serving as the control core, has programmable capabilities and is used to control the memory chip, temperature sensor, control switch, and charging status indicator. The memory chip is used to store the program code required for the operation of the microcontroller, the threshold values ​​of each power supply parameter, and historical working status data; The temperature sensor is used to collect the operating temperature of the power board in real time and transmit the operating temperature to the microcontroller; if the operating temperature exceeds a preset threshold, the microcontroller can trigger an early warning. The control switch is a main power / backup power switching switch, used to allow the microcontroller to receive status signals to realize the switching control between main power (external 220V power supply) and backup power (internal battery / external battery power supply); The charging status light is used to indicate the charging status of the internal battery.

[0025] In addition, such as Figure 2 He Ru Figure 3 As shown, the microcontroller has an RS485 communication interface and a USB communication interface; The microcontroller is connected to the front panel via the RS485 communication interface for data interaction. The microcontroller connects to the PoE board via the USB communication interface for data exchange.

[0026] In addition, such as Figure 3 The diagram shows the overall structure of the intelligent verification all-in-one machine. The industrial control computer is connected to the POE board and the front panel via USB data cables for data interaction. The POE board is connected to the video server via a network cable. The communication board is connected to the IO board via a 6P ribbon cable. The communication board is connected to the first interface of the wireless module via a USB data cable. The second interface of the wireless module is connected to the industrial control computer via a USB data cable.

[0027] Furthermore, such as Figure 4 As shown, the power board also includes: an AD circuit and a control circuit; The AD circuit is connected to the power management circuit and the microcontroller, respectively, and the control circuit is connected to the power management circuit and the microcontroller, respectively. The AD circuit is used to read the operating status parameters of each channel from the power management circuit and send them to the microcontroller, so that the microcontroller can send the operating status parameters of each channel to the front panel and the POE board respectively. The control circuit is used to receive control commands sent by the POE board and forwarded by the microcontroller, and send the control commands to the power management circuit.

[0028] In this embodiment, the microcontroller reads the current and voltage data collected by the AD circuit, judges whether the data is normal, and displays it on the front panel; the microcontroller judges whether the power supply data of each channel is normal and performs control management; the microcontroller can independently supply power without interference through the control circuit, increasing fault tolerance and reducing failures; the microcontroller is programmable, realizing power initialization, power supply information collection, fault judgment, independent control of power supply circuit, data uploading, and execution of external commands; the industrial control computer can display the power supply status and can also control and manage the power supply of each channel through the microcontroller and control circuit.

[0029] In summary, in this embodiment, the microcontroller is the core of the power board's management. The microcontroller connects to the front panel via an RS485 interface, sending power supply parameters such as voltage, current, and temperature collected by the AD circuit to the front panel display. The microcontroller also communicates with the PoE board via a USB interface, uploading the power supply status data required by the PoE board and forwarding power supply control commands from the PoE board to the control circuit, thereby regulating the power management circuit output. Additionally, the industrial computer connects to both the front panel and the PoE board via USB: it obtains summary power supply status information from the front panel and port power supply data from the PoE board, and can send control commands to the PoE board, which are then transmitted to the microcontroller, enabling remote control of each power supply path.

[0030] This embodiment effectively solves the problem of sudden power outages causing operational disruptions: when the external 220V power supply is normal, it can stably power the entire unit and related external equipment while charging the internal battery. In the event of a power outage, the internal battery provides initial power, and once depleted, it can switch back to the external battery. It also overcomes the shortcomings of existing UPS power supplies, such as the inability to provide multiple 12V, 24V, and 53V outputs, the inability to be miniaturized, and the lack of USB data transmission and programming capabilities. In this embodiment, the power board can output 7 12V channels (for video servers, industrial PCs, etc.), 1 24V channel, and 1 53V channel (for the PoE board). Combined with microcontroller programmable control (reading AD data to monitor status and independently controlling power supply to improve fault tolerance), and through RS485 / USB communication, the power supply status can be displayed in real-time on the front panel and industrial PC, ensuring continuous and stable operation of material vehicle entry and exit.

[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
