agv cotroller And even the core of the entire AGV, which controller should I choose? According to the author's experience, from the hardware point of view, the vehicle controllers used by AGV are basically divided into the following three types:
1. PLC: Representative products such as Siemens S7-1200 and 1500 series, using AGV manufacturers have Jiashun, Jiateng. PLC is known for its good stability and high reliability, but its long term is logic control, and generally can only do simple motion control. The price of Siemens PLC is about 2,000 yuan to ￥12,000.
2. Industrial computer: On behalf of products such as Beckhoff's CX5130, the manufacturer has a Kunming ship and a Robert Mavericks. The industrial computer is actually a computer, but it has been carefully designed to have strong anti-interference ability, and can be used in harsh industrial environments such as vibration and electromagnetic radiation. The industrial computer is compact and compact, and it can run a common operating system, such as Windows and Linux. In the case of Beckhoff, after installing its TwinCAT control software, a real-time kernel is inserted into the Windows operating system to turn the computer into a real-time control system suitable for industrial applications. The price of the Beckhoff industrial computer is about ￥5,000 to ￥30,000 .
3. Single-chip microcomputer: representative products such as STM32, use manufacturers have Haitong, machine. Compared with the former two, the price of the single-chip microcomputer is low, and the cost of peripheral devices is at most a thousand yuan. One disadvantage of using a microcontroller is that if you want to make a mature product, you need to spend a lot of effort designing external circuits and various underlying algorithms. The software development environment may be worse.
The above classification does not mean that the three are clearly defined. For example, the core chip of PLC may be a single-chip microcomputer; the programming language of the industrial computer is likely to adopt the ladder diagram, ST and other languages used in the PLC field; the microcontroller can also be loaded above. The operating system thus forms a complete controller. Therefore, although they each have their own applicable fields, they will complement each other and evolve into a situation in which you and me have you.
The IKV AGV controller uses products from brands such as Curtis, Curtis, and zapi. These controllers integrate sophisticated navigation and motion control algorithms, saving users a lot of work, and their stability and protection levels are higher, but their price Also higher.
