Description

Technical Field

[0001] This invention relates to the field of weighbridges, and more particularly to a vehicle intelligent load quality detection system. Background Technology

[0002] Weighbridges use multiple sensors to measure the weight of loaded vehicles. The weight data from these sensors is transmitted to a display instrument, which then shows the final weight of the loaded vehicle.

[0003] Existing weighbridges use current-output type pressure sensors to output load measurement signals, which are then converted into load signals by a controller. Due to the limited functionality of the instrument display, the current output signal is susceptible to electromagnetic interference, requiring shielded cables, which increases costs. Furthermore, since the sensor data needs to be processed by analog resistors and display instruments, users are unaware of any malfunctions in these instruments, affecting the weighbridge's measurement data.

It should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of protection of this invention. In the drawings, the same reference numerals are used to refer to the same parts. Wherein: Figure 1 The illustration shows a schematic diagram of a vehicle intelligent load mass measurement method according to an embodiment of the present invention. Detailed Implementation

[0017] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0018] Example 1 According to one embodiment of the present invention, Figure 1 The diagram illustrates a method for measuring the intelligent load mass of a vehicle. The vehicle is parked on a sensor surface, and the weight data at various locations is acquired through the sensors. The weight data is processed by an analog resistor, which is adjusted based on the sensor's position and the length of the wiring on the sensor surface. The processed data is then transmitted to a display instrument, which displays the data from each sensor and the total weight data after processing the data from each sensor.

[0019] The sensor is a voltage output type sensor, which has strong anti-interference ability. The display instrument is a comprehensive display instrument that can display the weight data of each sensor and the total weight data after data processing. Multiple voltmeters are connected to multiple sensors individually, and the voltmeters display the voltage values ​​output by the sensors.

[0020] The error controller is connected to the sensor, cylinder, voltmeter, analog resistor, and display instrument to acquire the pressure data from the cylinder to the sensor, the voltmeter data, the analog resistor data, and the display instrument data.

[0021] The error controller processes the voltmeter data to obtain the sensor's weighing data. (1) Where: W is the weighing data from the sensor; V out It is the voltage data from the voltmeter; V offset It is the zero-point output voltage, that is, the voltage value of the sensor when it is unloaded; S is the sensitivity coefficient of the sensor.

[0022] The weighing data from the sensor is compared with the pressure data from the cylinder on the sensor; (2) Where: α is the proportionality coefficient; W is the weighing data of the sensor; W pressure It is the pressure data of the cylinder on the sensor; Determine the working status of the sensor; The sensor works normally when α ≤ 0.1%. When 0.1% < α ≥ 0.2%, the sensor error is too large, and the sensor needs to be adjusted. When α > % , the sensor error is too large, and the sensor should be replaced.

[0023] The voltmeter data is acquired and combined with the analog resistance data to obtain the theoretical display data. The processed theoretical display data is compared with the sensor data displayed on the instrument, and the working status of the instrument is determined by the theoretical display data.

[0024] (3) Where: V out This is voltmeter data processed using analog resistors; V sensor For voltmeter data; R pot For analog resistance data; R source This is the internal resistance of the voltmeter.

[0025] V out Substitute the data back into formula (1) to calculate the theoretically displayed sensor data. Compare this data with the sensor data displayed on the existing display instrument. If the data are consistent, it indicates that the analog resistor is working normally.

[0026] The theoretical sensor data of each sensor is added together to obtain the total weight of the vehicle. This data is then compared with the total weight data displayed on the existing instrument panel. If the data match, it indicates that the instrument panel is working properly.

[0027] Example 2 A vehicle intelligent load quality calibration and detection system The cylinder module is used to apply pressure to the sensor; The sensor module is used to acquire pressure data on the sensor surface; The analog resistance module processes the pressure data from the sensor module based on the sensor's location and the sensor's circuit losses. The display instrument module processes the data processed by the analog resistance module again, and the processed data is displayed on the instrument. The voltmeter module acquires the voltage data output by the sensor. The error controller module acquires theoretical data of the pressure applied by the cylinder module to the sensor, voltmeter data, analog resistance data, and display data of the display instrument. It then compares the data to determine the working status of the sensor module, analog resistance module, and display instrument module.
