The highway construction industry, due to its unique engineering characteristics, is characterized by hardship, dirt, and danger (referred to as the 3K phenomenon in foreign countries), gradually becoming a less attractive industry. In addition, the aging of the original road workers and the reduction of skilled workers have caused many difficulties in the development of the industry. To change this situation, various parties attach greater importance to the automation and intelligence of road machinery. This is mainly manifested in the widespread use of non-contact sensing technologies such as laser and ultrasound, as well as computer technology, making operation more labor-saving, easy, and comfortable. Not only do large machinery achieve automatic control, but small machinery also achieve automation, and a random mass automatic detection and control system is added to ensure the quality of the project and improve construction efficiency.
