Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] In order to realize the purpose that the weighing device can acquire the whole vehicle weight of the commercial vehicle in real time and self-check, the embodiment of the present application provides an intelligent weighing measurement and control device of a commercial vehicle, as shown in the figure, which can include: Figure 1

[0029] The weighing sensor, the weighing display screen and the weighing controller; wherein,

[0030] The weighing sensor is connected with the weighing controller, the weighing display screen and the weighing controller two by two respectively;

[0031] The weighing sensor is arranged on the front axle, the middle axle and the rear axle of the commercial vehicle;

[0032] The weighing sensor is arranged on the front axle, the middle axle and the rear axle of the commercial vehicle;

[0033] The weighing controller is used to determine the total weight of the commercial vehicle and the status information of the weighing sensor based on the real-time voltage signal; based on the status information, it determines the working status of the intelligent weighing and control device; and sends the total weight of the commercial vehicle and the working status of the intelligent weighing and control device to the weighing display screen.

[0034] The weighing display screen is used to display the real-time weight of the commercial vehicle and the working status of the intelligent weighing and control device.

[0035] Specifically, the load cells are connected to the load cell controller, the load cell display screen, and the load cell controller via a CAN bus, forming a closed-loop communication network.

[0036] Please refer to the side view of the weighing sensor in the intelligent weighing and control device after installation in a commercial vehicle. Figure 2 For the top view, please refer to Figure 3 .from Figure 2 and Figure 3 As can be seen from the diagram, the weighing sensor includes six pressure sensors symmetrically arranged at corresponding positions on the front, middle, and rear axles of the commercial vehicle. These corresponding positions are located in the upper chambers of the corresponding air springs on the front, middle, or rear axles of the commercial vehicle. Specifically, the six pressure sensors can be designated as: First Pressure Sensor 1, Second Pressure Sensor 2, Third Pressure Sensor 3, Fourth Pressure Sensor 4, Fifth Pressure Sensor 5, and Sixth Pressure Sensor 6. As shown in the diagram, First Pressure Sensor 1, Second Pressure Sensor 2, and Third Pressure Sensor 3 are all located on one side of the commercial vehicle, while Fourth Pressure Sensor 4, Fifth Pressure Sensor 5, and Sixth Pressure Sensor 6 are all located on the other side; the pressure sensors on both sides are symmetrically arranged. Optionally, the pressure sensors can be hydraulic sensors, which can be installed in the upper chambers of the air spring suspension of the commercial vehicle.

[0037] During the weighing process of the intelligent weighing and control device, the hydraulic pressure sensor monitors the pressure in the loading oil chamber in real time, converting the pressure into an analog voltage signal that can be recognized by the weighing controller. Changes in the analog voltage signal are transmitted to the weighing controller via the CAN bus in the form of CAN message data. Based on the received CAN message data, the weighing controller calculates the total weight of the commercial vehicle. The total vehicle weight includes the sum of the vehicle's own weight and the mass of the cargo it carries. The weighing principle is as follows: six pressure sensors installed on the gas springs of the front and rear axles measure the vehicle load, and the total vehicle load mass is calculated by calculating the vehicle's center of gravity. The working principle is as follows: the pressure of the gas in the cylinders of the hydraulic pressure sensors is used to indirectly measure the weight of the front and rear axles. The total vehicle load mass is calculated and displayed by combining the vehicle's center of gravity value with the actual value measured by the customer.

[0038] The intelligent weighing measurement and control device provided in the embodiment of the utility model utilizes the weighing sensor and the weighing controller to acquire the whole vehicle weight of the commercial vehicle in real time, and displays the whole vehicle weight of the commercial vehicle in real time through the weighing display screen, so that the driver can acquire the whole vehicle weight of the commercial vehicle driven by the driver in real time.

[0039] The weighing display screen is a weighing measurement product with high intelligence, and its principle is that the weighing controller internally adopts the CAN communication message form to acquire the signals collected by the six pressure sensors, and transmits the signals to the weighing display screen in the form of CAN message to display the total weight of the vehicle cargo in real time and the working state of the intelligent weighing measurement and control device.

[0040] Specifically, the working state of the intelligent weighing measurement and control device can include normal working state and abnormal working state; when the intelligent weighing measurement and control device is in the normal working state, the weighing display screen displays normal working state; when the intelligent weighing measurement and control device is in the abnormal working state, the weighing display screen displays abnormal working state and the position of the abnormal pressure sensor.

[0041] Specifically, when the intelligent weighing measurement and control device is in the abnormal working state, the state information of each pressure sensor in the weighing sensor acquired by the weighing controller is used to confirm the pressure sensor that has faults or is abnormal, and the position of the abnormal pressure sensor is displayed on the weighing display screen. It can be understood that the state information of the weighing sensor acquired by the weighing controller can include the on-off state of each pressure sensor and the working voltage of each pressure sensor. For each pressure sensor, when the pressure sensor is in the off state or the working voltage of the pressure sensor is lower than the preset minimum voltage or the working voltage is higher than the preset maximum voltage, it indicates that the pressure sensor has faults, and the weighing display screen displays that the pressure sensor has faults, so that the driver can intuitively obtain the position of the abnormal pressure sensor. The driver can choose to continue driving without overloading, to stop and maintain the intelligent weighing measurement and control device, and then continue driving after confirming that the vehicle is not overloaded, or to choose another processing mode. The normal working voltage of the pressure sensor can be 0.4V-4.5V, the preset minimum voltage can be 0.4V, and the preset maximum voltage can be 4.5V.

[0042] The intelligent weighing measurement and control device provided in the utility model utilizes the weighing controller to acquire the state information of the weighing sensor in real time, realizes real-time acquisition of the working state of the intelligent weighing measurement and control device, and accurately locates the position of the abnormal pressure sensor when the intelligent weighing measurement and control device is abnormal, so that the driver can quickly find the abnormal condition and the abnormal pressure sensor, quickly process, and avoid the overloading behavior of the commercial vehicle caused by the fact that the driver does not timely detect the abnormality of the traditional weighing measurement and control device.

[0043] As preferred, another preferred embodiment of the intelligent weighing measurement and control device provided by the embodiment of the utility model is shown in the figure, which can further comprise: Figure 4

[0044] An alarm and / or a Beidou module.

[0045] The alarm is connected with the weighing controller, and is used to send an alarm signal when the working state of the intelligent weighing measurement and control device is abnormal.

[0046] The Beidou module is connected with the weighing controller, and is used to provide an emergency help or a backup positioning function for the commercial vehicle.

[0047] The alarm can be used to send an acoustic alarm signal when the intelligent weighing measurement and control device is in an abnormal working state, so as to prompt the driver to handle the abnormality of the intelligent weighing measurement and control device in time and avoid overloading. The Beidou module can be used as a backup positioning device to provide positioning service for the driver when the positioning function of the mobile phone or the vehicle-mounted positioning system fails or an unexpected situation occurs. In addition, the Beidou satellite short message system can be used for communication or help in extreme situations.

[0048] The embodiment of the utility model uses the weighing sensor in combination with the weighing controller to acquire the whole vehicle weight of the commercial vehicle in real time, and displays the whole vehicle weight of the commercial vehicle on the weighing display screen in real time, so that the driver can obtain the whole vehicle weight of the commercial vehicle in real time. At the same time of weighing, the weighing controller is used to acquire the state information of the weighing sensor in real time, so as to realize real-time acquisition of the working state of the intelligent weighing measurement and control device. When the intelligent weighing measurement and control device is abnormal, the position of the pressure sensor where the abnormality occurs can be accurately located, so that the driver can quickly find the abnormality and handle it quickly, and overloading of the commercial vehicle caused by the fact that the driver does not notice the abnormality of the traditional weighing measurement and control device in time is avoided.
