Car washer "brain"--PLC and CPU

Currently, car washer "brains" are divided into PLC (industrial programmable logic controller) and CPU (microcontroller), it directly determines the performance of car washer. CPU on the market today used mostly imported car washing machine car wash machine. In China wash car machine temporarily also is growth stage, and developed after more than 30 years of development, wash car machine technology has comparison mature has, such as Japan wash car machine has is using CPU central processing unit of computer intelligent wash car machine fourth generation has, and domestic wash car machine due to by yield of limit cannot has bear expensive of around hardware early development costs, most using PLC operating system, was called imitation shaped wash car machine.

Take a popular example is the difference between what assumptions we build cars, if you are using PLC then is equivalent to having a parts library, which has a steering wheel, engine, body, and so on. In finding the right and then you can assemble one. If you don't have the right, if it can be replaced with the other parts that are the best (possible trouble, but better than nothing), if there is no way (because different manufacturers or with different parts of the series here cannot be generic, while others have the right, but not available). If a parts problems you cannot repair because you don't knows how it made, course they wonder where to issue. If the CPU is the equivalent of having a lathe, each part needs to own building. Here you have the maximum flexibility, you can do anything you want. These things are all self-made, so you can have independent intellectual property rights.1323 Infrared Themometer
