Basic principle of AGV handling equipment
The guidance of AGV is to calculate the actual control command value of AGV according to the position information obtained from the AGV guidance sensor and the target value provided by the AGV path, that is, to give the set speed and steering angle of AGV, which is the key of AGV control technology. In short, the guidance control of AGV is AGV trajectory tracking.
AGV technology and current situation
(1). Basic concept of AGV handling equipment
According to the definition of American Logistics Association, AGV (Automated Guided Vehicle) refers to a small transport vehicle equipped with electromagnetic or optical guidance device, capable of driving according to the specified guidance route, with trolley operation and parking device, safety protection device and various load transfer functions. In China's national standard "Logistics Terminology", the AGV trolley is defined as a transport vehicle with automatic guidance device, which can drive along the specified path, and has programming and parking selection device, safety protection device and various material transfer functions on the vehicle body.
(2). Features of AGV handling equipment
AGV trolley can accurately walk and park to the designated place according to the path planning and operation requirements, and automatically complete a series of transportation operations. AGV trolley has the advantages of high automation level, high working efficiency, strong controllability and good safety. In the automatic logistics system, AGV can best reflect its automation and flexibility, and realize efficient, economic and flexible unmanned transportation.
(3). The function of AGV handling equipment shows the development of versatility
With the wide application of AGV handling equipment, the market has increasingly higher requirements for the adaptability, functional requirements, positioning accuracy, and bearing capacity of AGV handling equipment, and the functions of AGV handling equipment are developing in versatility. Taking the carrying capacity as an example, domestic AGV enterprises generally have a product carrying capacity of less than 3 tons. At present, AGV with a carrying capacity of more than 10 tons or even dozens of tons also has a certain demand. Due to the early development of AGV in foreign countries and the wider application of AGV in the industry, there is still a certain gap between China and foreign countries in the functional diversity of vehicle models.
3、 Prospects for the development of AGV
From the perspective of AGV development trend, the AGV industry is very worthy of investment, and the development potential of AGV is also huge. On the one hand, with the increasing abundance of AGV products, AGV will combine more with the Internet and big data technology to improve the perception ability and independent decision-making ability of the logistics system and significantly improve the degree of intelligence. On the other hand, with the development of the AGV industry, the increasing demand for AGV, the maturity of technology and the reduction of cost will promote the further expansion of the application scope of AGV.
