Automatic detection device and control method of rutting tester

Abstract

The invention discloses a wheel tracking tester automatic detection device which comprises a square base, a turbo-worm reducer, a hollow disc-shaped support part, a butterfly force value sensor and aplurality of linear temperature and humidity sensors, wherein a columnar groove is formed in the upper surface of the square base coaxially, a plurality of columnar guide pillars are uniformly arranged in the groove, close to the periphery; the turbo-worm reducer is fixedly arranged in the middle of the groove, an encoder is arranged at the center of the upper surface of the turbo-worm reducer; the hollow disc shaped support part is provided with columnar through holes matched with the guide pillars, is coaxial with the base and is sleeved on the guide pillars in a vertically moving way; the butterfly force value sensor is fixedly arranged above the encoder by a thread bushing; the lower ends of the linear temperature and humidity sensors are arranged at four opposite angles of the base. The invention also provides a control method of the wheel tracking tester automatic detection device, which adjusts trial wheel displacement and voltage of a detection circuit based on the BP neural network in wheel tracking tester automatic detection. According to the invention, integrated automatic detection is realized; and meanwhile, the accuracy of the test system in a common test environmentis increased.

Description

technical field [0001] The invention relates to the field of rutting tests, in particular to an automatic detection device for a rutting tester. Background technique [0002] The rutting tester is mainly used for the determination of the high-temperature anti-rutting ability of asphalt mixture, and can also be used for auxiliary inspection of asphalt mixture ratio design. The rutting tester is the most ideal simulation device for road compaction. The characteristics of the prepared samples are very similar to those of the road compaction layer, and can also be directly used for rutting tests. The rutting tester is widely used in road construction and laboratory testing. [0003] In recent years, my country has vigorously built transportation infrastructure and increased investment in transportation infrastructure. In the next few years, my country's highway construction market will still have a large market space, especially in the western region, where investment in road...
