Embodiment Construction
[0018] In order to further illustrate the technical details and its advantages of the present invention, it will be described with reference to the drawings.
[0019] like figure 1 As shown, an automatic detection system of excavator traveling speed and linear offset includes an MPU main controller, the main controller connects the laser displacement sensor A and a laser displacement sensor B, the laser displacement sensor A and The laser displacement sensor B is arranged on a straight line and the direction is parallel to the initial direction of the measured excavator.
[0020] In this embodiment, the laser displacement sensor A and the laser displacement sensor B are diffuse reflective self-transmitted self-receiving type, and the ranging range is greater than 10 meters. The MPU main controller includes a master chip, a power supply, a power supply output pin, a signal input pin, and a display module with a power supply output pin. Write a prefabricated control program, includi...

An automatic detection system and method for the driving speed and linear offset of an excavator are disclosed. The automatic detection system comprises an MPU main controller, the main controller is connected with a laser displacement sensor A and a laser displacement sensor B, the laser displacement sensor A and the laser displacement sensor B are arranged on the same straight line, and the direction of the laser displacement sensor A and the laser displacement sensor B is parallel to the initial driving direction of the excavator to be detected; automatic detection of the driving speed and the linear offset is achieved, a user only needs to install and adjust the distance between the two laser displacement sensors and the distance between the laser displacement sensors and the excavator according to the current field environment, then adjusts the walking posture of the large hydraulic excavator, and presses down a starting switch. The automatic detection system can measure the time that the large hydraulic excavator travels for a certain distance and the starting distance and the ending distance between the laser displacement sensor and the large hydraulic excavator, and the traveling speed and the linear offset can be obtained through simple calculation.
Description
Technical field [0001] The present invention relates to the field of engineering machinery testing, and in particular, an automatic detection system and method of traveling speed and linear offset. Background technique [0002] When a large hydraulic excavator is a type test, there is a need to measure the travel speed and line offset of a large hydraulic excavator, thereby judge the walking performance of the model. Among them, the speed of travel is the time experienced by the large hydraulic excavator along a straight line, and the line offset is caused by the difference in the average speed of the left and right crashes of the excavator, reflecting the technical level of the excavator driving control system and Control accuracy is a major technical indicator of the excavator. Therefore, when the excavator is unbalanced, even if the controller is pushed into the bottom excavator, it is not walking along the straight line, but is advanced along a circular arc along a certain di...
