Benefits of technology

This patented technology allows vehicles equipped with an electronic balance system (EBS) to measure weight accurately without having any extra equipment attached or connected to them. It uses advanced cameras that capture images from different angles around its axis to determine changes caused by tilting movements on both sides of the EBS's armrest. By analyzing these data, this technology helps drivers make informed decisions about how best they should move their car based upon factors like tire pressure levels, road conditions, etc., improving overall performance and safety during driving operations.

Problems solved by technology

This patented technical solution described in the patents describes how to efficiently and precisely determine when a specific carrier needs to be loaded/unloaded without adding too much effort compared to other cars during their lifespan.

Embodiment Construction

[0021] Such as figure 1 As shown, this embodiment provides a method for collecting boom angle parameters of a vehicle-mounted hydraulic weighing device, which consists of the following four steps: step A captures the boom angle, step B captures the number of sensor sampling points and sampling frequency, and step C Calculate the boom angle change time and step D calculate the boom change angular rate.

[0022] The main design idea of ​​this embodiment is to abandon the existing technology of only using the proximity switch to control the change of the boom angle in the form of discontinuous points, avoiding the use of expensive inclination sensors and acceleration sensors, and using incremental photoelectric encoders to Perceive the change of the boom angle, and determine the time domain of the boom angle change through the sensor signal sampling points and sampling frequency of the weighing device, so as to determine the change rate of the boom angle. Since the incremental phot

Abstract

The invention discloses an acquisition method for a movable arm angle parameter of a vehicle-mounted hydraulic weighing device. In the method, an incremental photoelectric encoder is used for sensing change of a movable arm angle; a time domain for the change of the movable arm angle is determined through signal sampling point number and sampling frequency of a sensor of the weighing device, thereby determining the change rate of the movable arm angle; and a starting point and an ending point of the angle change are detected by taking a proximity switch as the photoelectric encoder. The method respectively comprises the following execution steps of: A, acquiring a movable arm angle change value; B, acquiring the sampling point number and the sampling frequency of the sensor; C, calculating the change time of the movable arm angle; and D, calculating the movable arm change angular rate. In the method, by acquiring the movable arm angle change rate, the weighing operation behavior of a driver is effectively regularized, so that the detection accuracy of the hydraulic weighing device is improved.
