[0024] First, the application scenarios applicable to the present application are introduced. The present application can be applied to the technical field of weighing instruments.

[0025] The existing weighing platform is often not equipped with a special trigger to accurately detect the time point when the vehicle enters, which causes the system to be unable to respond to the arrival of the vehicle; in addition, some weighing platforms attempt to set a trigger at a fixed position of the weighing scale platform, but this design has limitations. If the vehicle does not accurately drive to the fixed position, the trigger cannot be effectively triggered.

[0026] To solve the problems of the above at least one aspect, the embodiments of the present application provide a vehicle weighing system and a one-line multi-axle vehicle identification system, which comprises: a weighing scale platform, the weighing scale platform is rectangular, the weighing scale platform comprises a weighing area and a strip-shaped trigger area, the strip-shaped trigger area is arranged at a position close to the vehicle entering side of the weighing scale platform; a plurality of triggers, arranged above the weighing scale platform, the plurality of triggers are arranged in a single row and a single column in the strip-shaped trigger area, and each trigger is arranged adjacent to each other; a plurality of weighing sensors, arranged below the weighing scale platform, and each weighing sensor is arranged at a corresponding right angle position of the weighing area of the weighing scale platform. The weighing area of the present application is used to actually measure the weight of the vehicle, and the strip-shaped trigger area is located on one side of the weighing scale platform where the vehicle enters, which is used to detect the arrival of the vehicle; the plurality of triggers are carefully arranged in the strip-shaped trigger area and arranged in a single row and a single column in a close manner, and at least one trigger will be triggered when the vehicle enters the area, so as to respond to the arrival of the vehicle; the plurality of weighing sensors are installed below the weighing scale platform, and each sensor is located at a right angle position of the weighing area. Such a layout ensures that the vehicle weight measurement can be responded in time no matter where the vehicle is parked on the weighing scale platform.

[0027] Please refer to Figure 1 , Figure 1 The vehicle weighing system provided by the embodiments of the present application is shown in one of the schematic diagrams thereof; as shown in Figure 1 , the vehicle weighing system provided by the embodiments of the present application comprises a weighing scale platform 10, a first lower weighing sensor 11, a second lower weighing sensor 12, a first upper weighing sensor 13, a second upper weighing sensor 14 and a trigger 15.

[0028] The weighing scale platform 10 is rectangular, and the weighing scale platform 10 comprises a weighing area and a strip-shaped trigger area, the strip-shaped trigger area is arranged at a position close to the vehicle entering side of the weighing scale platform 10; a plurality of triggers 15 are arranged above the weighing scale platform 10, the plurality of triggers 15 are arranged in a single row and a single column in the strip-shaped trigger area, and each trigger is arranged adjacent to each other; a plurality of weighing sensors are arranged below the weighing scale platform 10, and each weighing sensor is arranged at a corresponding right angle position in the weighing area of the weighing scale platform 10.

[0029] The shape of the trigger is preferably rectangular, and the total length of the long sides of all the triggers is equal to the length of the strip-shaped triggering area. The wide sides of each trigger are arranged side by side without gaps and cover the entire strip-shaped triggering area. Preferably, 12 triggers can be selected, and the vehicle tire width and tire spacing detection can be determined according to the position detected by the triggers.

[0030] The four load sensors are used to locate the driving position of the vehicle on the scale platform and determine the weight of the vehicle according to the load data detected by the load sensors. The greater the load data, the closer the vehicle is to the load sensor.

[0031] Here, the weighing scale platform 10 adopts a rectangular design, and its length and width can be adjusted according to the actual application scenario to accommodate various vehicles for weighing.

[0032] In an optional embodiment, the weighing area includes a first short side, a second short side, a first long side, and a second long side. The first short side is arranged opposite to the second short side, and the first long side is arranged opposite to the second long side. The length of the first short side is the same as the length of the strip-shaped triggering area, and the first short side directly contacts the boundary of the strip-shaped triggering area without gaps. The plurality of load sensors include a first upper load sensor 13, a second upper load sensor 14, a first lower load sensor 11, and a second lower load sensor 12.

[0033] Among them, the first upper load sensor 13 is arranged at the right angle position formed by the first long side of the weighing scale platform 10 and the strip-shaped triggering area; the second upper load sensor 14 is arranged at the right angle position formed by the second long side of the weighing scale platform 10 and the strip-shaped triggering area; the first lower load sensor 11 is arranged at the right angle position formed by the first long side of the weighing scale platform 10 and the second short side; and the second lower load sensor 12 is arranged at the right angle position formed by the second short side of the weighing scale platform 10 and the second long side.

[0034] Here, the strip-shaped triggering area is arranged near the vehicle entry side of the weighing scale platform, that is, the only way for the vehicle to enter the scale platform. Such an arrangement can ensure that the vehicle is detected as soon as it enters the scale platform, thereby triggering the load sensor to start detection in a timely manner.

[0035] When the vehicle enters the strip-shaped triggering area, at least one trigger will be triggered. After the trigger is triggered, it will immediately send a signal to the processor to inform the system that the vehicle has entered. After receiving the signal of the trigger, the processor will control the load sensor to start detecting the weight of the vehicle. The load sensor will collect the weight data of the vehicle in real time and send it to the processor for display.

[0036] In an embodiment, the trigger 15 sends a trigger signal to the processor when detecting that a vehicle enters, and the processor sends a start test signal to each weighing sensor after receiving the trigger signal, so that each weighing sensor starts detecting the weight of the vehicle entering the weighing platform.

[0037] Please refer to Figure 2 , Figure 2 The second schematic view of the vehicle weighing system provided by the embodiment of the application; as shown in Figure 2 The vehicle weighing system provided by the embodiment of the application further includes a dual-core circuit board 20, a first processor 21, a second processor 22, an LCD display screen interface module 23, a UART display screen interface module 24, a JTAG debugging interface module 25, a serial communication interface module 26, and an Ethernet interface module 27.

[0038] The dual-core circuit board 20 includes the first processor 21 and the second processor 22, the output pin of each trigger is connected with the corresponding input pin of the first processor 21, and the output pin of each weighing sensor is connected with the corresponding input pin of the first processor 21.

[0039] For example, the dual-core circuit board is arranged in a monitoring terminal, and the monitoring terminal is arranged around the weighing platform, so as to display the weight information of the vehicle detected by the weighing platform.

[0040] Preferably, the model of the first processor is STM32F407, and the model of the second processor is MCIMX6Y2CVM08AB.

[0041] Preferably, the transmission mode between the first processor 21 and the second processor 22 is at least one of SPI transmission, UART bus transmission, and Ethernet transmission.

[0042] The dual-core circuit board 20 integrates the first processor 21 and the second processor 22, the data processor adopts an ARM407+MCIMX6Y dual-core architecture, the first processor 21 corresponds to an ARM407 module, the second processor 22 corresponds to an MCIMX6Y module, and the two processors work cooperatively to process the data from the trigger 15 and the sensor (including the first lower weighing sensor 11, the second lower weighing sensor 12, the third upper weighing sensor 13, and the fourth upper weighing sensor 14) of the weighing platform 10.

[0043] The first processor 21 is the main data processing unit of the system, responsible for receiving and processing raw data from the triggers 15 and sensors. Its model is STM32F407, which is known for its high performance, low power consumption and rich peripheral resources, making it ideal for real-time data processing and control systems. The first processor 21 implements high-speed A / D conversion of each weighing scale 16 sensor and transmits the converted sensor weighing information to the second processor 22.

[0044] The second processor 22 is more responsible for data communication and system management tasks. Its model is MCIMX6Y2CVM08AB, which provides strong network communication and data management capabilities for the system.

[0045] The ARM407 module is responsible for A / D conversion of 16-channel sensor signals, recording weighing moments, and other tasks. It transmits interrupt information from each weighing sensor to the MCIMX6Y module via the UART bus. The MCIMX6Y module receives and stores the interrupt information from each weighing sensor of the ARM407 module and records the real-time weighing state of each weighing sensor. When a weighing sensor detects a weight change, it triggers an interrupt signal, which is captured by the ARM407 module's interrupt controller and prepared for transmission to the MCIMX6Y module via the UART bus. The interrupt information can include the weighing sensor's ID, converted digital value, timestamp, and other information.

[0046] Here, the ARM407 module collects data from all triggers and all weighing sensors and packages it as interrupt information to send to the MCIMX6Y module.

[0047] During actual weighing, when a vehicle passes over the weighing scale, the triggers and multiple weighing sensors transmit the detected signals to the ARM407 module. The ARM407 module converts the analog signals output by each weighing sensor into digital signals using its built-in A / D converter (ADC) and transmits them to the MCIMX6Y module. The sampling frequency of a single sensor is 1000 times per second, and the dual-core circuit board of the present application can support parallel signal processing of 16 weighing sensors.

[0048] The ARM407 module has independent buffers for each weighing sensor data, records and stores the weighing data, and performs analog-to-digital conversion. The signals can be transmitted to the MCIMX6Y module via the UART bus.

[0049] After the MCIMX6Y module receives the interrupt information, the trigger state of each trigger at a time of passing through the axle is determined through the upper scale threshold and the lower scale threshold, the state of each trigger is introduced into the tire type identification function, and thus the tire width, tire spacing, tire weight ratio, etc. of each axle of the vehicle are obtained; in combination with the weight change of the upper scale sensor, the single axle weight, the wheelbase, the axle group weight, etc. of the vehicle are comprehensively calculated. In combination with the lower scale sensor lower scale function, the scale platform axle information can be tracked at any time, and thus the complete vehicle weighing information at any time in a time of passing through the vehicle is obtained.

[0050] Data exchange and communication between the first processor 21 and the second processor 22 are carried out through flexible transmission modes, including but not limited to:

[0051] SPI transmission: serial peripheral interface (SPI) is a high-speed, full-duplex, synchronous communication protocol, suitable for short-distance, high-speed data transmission. In the dual-core circuit board 20, SPI transmission can be used for fast data exchange between the first processor 21 and the second processor 22.

[0052] UART bus transmission: universal asynchronous receiver-transmitter (UART) is an asynchronous serial communication protocol widely used in embedded systems. UART bus transmission allows the first processor 21 and the second processor 22 to transmit data without sharing the clock signal, increasing the flexibility and reliability of the system.

[0053] Ethernet transmission: Ethernet is a widely used local area network technology that supports high-speed, long-distance data transmission. In the dual-core circuit board 20, Ethernet transmission can be used for large data volume transmission between the first processor 21 and the second processor 22, or data synchronization and backup with a remote server.

[0054] The MCIMX6Y module has an embedded operating system, human-computer interaction function and data transmission function, supports network interface, I / O interface, RS422 interface, RS232 interface, I 2 C interface, supports LCD touch screen display, thereby realizing human-computer interaction, data uploading, data storage, etc.

[0055] After the MCIMX6Y module receives the interrupt information, the tire type calculation function, the vehicle wheelbase calculation function, the vehicle positioning function, the sensor timing function, the vehicle common weighing logic function, the vehicle following combination logic function are used to comprehensively calculate the tire type, axle type, vehicle type, axle weight, axle group weight, total weight, speed, etc. of the vehicle; and support operating system, human-computer interaction, data transmission, etc.

[0056] The vehicle weighing system further comprises a peripheral interface module, which comprises an LCD display screen interface module 23 and a UART display screen interface module 24, wherein the LCD display screen input pin of the LCD display screen interface module 23 is connected with the LCD display screen output pin of the second processor 22, and the UART display screen input pin of the UART display screen interface module 24 is connected with the UART display screen output pin of the second processor 22, so as to output the weighing data to a local display device for display.

[0057] Here, the data transmission path of the LCD display screen interface module 23 is that the plurality of weighing sensors send the collected signals to the first processor, the first processor sends the signals to the second processor, and the second processor sends the signals to the LCD display screen interface module 23; the LCD display screen interface module 23 is responsible for converting the data processed by the second processor 22 (such as vehicle weight, system status, etc.) into signals that can be recognized by the LCD display screen, so as to clearly and intuitively display on the screen. This is crucial for operators to quickly obtain weighing results and system status; the output pin of the second processor 22 is connected with the LCD display screen input pin of the LCD display screen interface module 23 through a specific interface circuit, and this connection mode usually involves the configuration of a data bus, a control signal line and a power line, so as to ensure the stable transmission of data and the normal work of the display screen.

[0058] The UART display screen interface module 24 communicates with a remote display screen or an embedded display screen controller through a UART protocol, so as to reduce cost and simplify wiring, receives serial data from the second processor 22, and then converts the serial data into a format that can be understood by the display screen for display on the display screen.

[0059] Here, the connection mode of the UART display screen interface module 24 is similar to that of the LCD display screen interface module 23, and the data transmission path of the UART display screen interface module 24 is that the plurality of weighing sensors send the collected signals to the first processor, the first processor sends the signals to the second processor, and the second processor sends the signals to the UART display screen interface module 24; the output pin (a pin specially used for UART communication) of the second processor 22 is connected with the input pin of the UART display screen interface module 24 through a serial port line (such as RS-232, RS-485 or a USB to UART adapter, etc.). This connection mode allows the system to realize remote data display or simplify the connection of the display device without increasing additional complexity.

[0060] The peripheral interface module further comprises a JTAG debugging interface module 25, which comprises a test data output pin, a test data input pin, a test clock pin and a test mode selection pin;

[0061] The test data output pin of the JTAG debugging interface module 25 is connected to the input pin of the second processor 22, the test data input pin of the JTAG debugging interface module 25 is connected to the output pin of the second processor 22, the test clock pin of the JTAG debugging interface module 25 is connected to the clock signal pin of the second processor 22, and the test mode selection pin of the JTAG debugging interface module 25 is connected to the mode selection pin of the second processor 22.

[0062] Here, the JTAG debugging interface module 25 is a debugging interface based on the JTAG (Joint Test Action Group) standard, which allows developers to perform boundary scan, debugging, programming, and troubleshooting on the system without removing the internal chips. The JTAG interface is widely used in the development and maintenance of embedded systems, microcontrollers, FPGA (Field Programmable Gate Array) and other devices.

[0063] Test data output pin (TDO): This pin is used to transmit test data from the second processor 22 to the JTAG debugger. During the debugging process, the second processor 22 outputs its internal state or test results through this pin for analysis by the JTAG debugger.

[0064] Test data input pin (TDI): This pin is used to transmit test data from the JTAG debugger to the second processor 22. Through this pin, developers can send debugging instructions, test vectors or data to the second processor 22 to control its behavior or trigger specific test modes.

[0065] Test clock pin (TCK): This pin provides the clock signal during the JTAG debugging process. The clock signal is generated by the JTAG debugger and is used to synchronize the transmission of test data. By adjusting the clock frequency, developers can control the speed and accuracy of the debugging process.

[0066] Test mode selection pin (TMS): This pin is used to control the state machine of the JTAG debugging interface, thereby switching between different debugging modes. By sending specific sequence signals to the TMS pin, developers can start boundary scan, enter debugging mode, exit debugging mode, or perform other operations.

[0067] In the vehicle weighing system, developers can use the JTAG debugging interface module 25 to debug the second processor 22, and by monitoring the internal state, register values and program counter of the processor in real time, developers can quickly locate and fix errors in the code.

[0068] In particular, the peripheral interface module further includes a serial communication interface module 26, wherein the serial communication interface module 26 includes a transmit data pin and a receive data pin; the transmit data pin of the serial communication interface module 26 is connected to the serial input pin of the second processor 22, and the receive data pin of the serial communication interface module 26 is connected to the serial output pin of the second processor 22.

[0069] Here, the transmit data pin (TXD): This pin is used to transmit serial data from the serial communication interface module 26 to the second processor 22. During data transmission, the serial communication interface module 26 converts the data to be transmitted bit by bit into a serial signal and sends it to the input pin of the second processor 22 through the TXD pin. The second processor 22 then receives and processes these data.

[0070] The receive data pin (RXD): This pin is used to receive serial data from the second processor 22. When the second processor 22 needs to send data to the serial communication interface module 26, it converts the data bit by bit into a serial signal and sends it to the RXD pin through its output pin. The serial communication interface module 26 then receives these data and may convert them into parallel data or other formats for subsequent processing.

[0071] In particular, the peripheral interface module further includes an Ethernet interface module 27, the Ethernet output pin of the Ethernet interface module 27 is connected to the Ethernet input pin of the second processor 22, and the Ethernet input pin of the Ethernet interface module 27 is connected to the Ethernet output pin of the second processor 22.

[0072] Here, the Ethernet interface module 27 is an interface for implementing network communication, which follows the Ethernet communication protocol and allows devices to be connected to a local area network (LAN) or a wide area network (WAN) through a network cable, thereby realizing the transmission and sharing of data. The Ethernet interface module 27 usually includes two parts: the physical layer (PHY) and the media access control layer (MAC), the former is responsible for handling data transmission at the physical layer, and the latter is responsible for data encapsulation and transmission.

[0073] The output pin: The output pin of the Ethernet interface module 27 is mainly used to send data to the second processor 22. When the Ethernet interface module 27 receives data packets from the network, it sends these data to the input pin of the second processor 22 through the output pin. The second processor 22 then processes these data, such as parsing, storing or forwarding.

[0074] The input pin of the Ethernet interface module 27 is used to receive data from the second processor 22. When the second processor 22 needs to send data to the network, it sends the data to the input pin of the Ethernet interface module 27 through the output pin. The Ethernet interface module 27 then encapsulates the data and sends it to the target device through the network cable.

[0075] Through the Ethernet interface module 27, the system can transmit weighing data, device status, and other information to a remote server or data center in real time for real-time monitoring and analysis by management personnel. With the help of the Ethernet interface module 27, the vehicle weighing system can realize remote monitoring. Management personnel can remotely access the system through the network to view real-time weighing data, device status, alarm information, etc., thereby realizing remote management and control of the system. The Ethernet interface module 27 also supports various network communication protocols such as TCP / IP, UDP, HTTP, etc., which makes it easy for the system to communicate and exchange data with other network devices. By adding additional network devices or modules, the functionality and performance of the system can be further expanded.

Such a layout ensures that the vehicle weight measurement can be timely responded regardless of the position of the vehicle parked on the weighing platform 10.

[0077] In the second aspect, the embodiments of the present application provide a one-line multi-axle vehicle identification system, which comprises the vehicle weighing system described above.
