[0039] Specifically, in this embodiment, the height of the first connecting rod 22 is set according to the actual measurement height.

[0040] The ultrasonic range finder regularly emits short and 200KHZ high-frequency sound waves, which propagate in the air at the speed of sound, and if they encounter an object, they will return to the sensor as an echo signal, so that the sensor can calculate the distance between the sensor and the target object by calculating the time interval between the emission of the signal and the reception of the echo. The distance between the sensor and the measured object is calculated by measuring the time of flight of the sound wave, not by the intensity of the sound wave. The detection distance of the ultrasonic range finder varies from 20mm to 10m, because the measurement is based on the time of flight of the sound wave, so the measurement accuracy is very high, and the resolution of some sensors can be less than 0.025mm. The ultrasonic range finder can pass through dusty air or fog, and even if the sensor head is covered with a thin layer of water vapor, it will not affect its function. The actual weighing condition is as shown in Figures 9-11 The high-frequency sound waves are emitted by the sensor as a three-dimensional cone, as shown in Figure 12 .

[0041] In actual use, one ultrasonic detection sensor is installed at each end of the edge of the weighbridge, and the ultrasonic detection sensor is connected to the on-off IO module through a signal line. When the sound wave is blocked, the sound wave sends a signal to the on-off IO module, and the weighing software extracts data from the database. When an alarm signal is detected, the system prohibits the saving of weighing system data, and the weighing process is terminated. The ultrasonic detection device for the weighbridge in the embodiment can measure the distance of objects at different positions, improve the measurement accuracy, and also facilitate user use. Through repeated testing and adjustment on site, the ultrasonic wave scanning can ensure that each height of the vehicle can be scanned.

[0042] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
