1, CAN-BUS
at least the vehicle to over 250,000 with such components, I’ll explain what is CAN-BUS, I use the most simple words so that you may know, in the past the engine to open later you can see a series of lines that are all gone, turned into a fiber, if I cut it into two words, if you do not touch, you can immediately see the light, the transmission speed is very fast, it costs overemphasized, very high. I can think of, this thing in a car when the link, even if a lot of line, the line is not packaged, plastic, and copper wire inside the package there, so plastic with a long time after the aging, not to mention car in the exercise of the temperature so high, so the plastic will break, will have a short circuit, the use of more than one year after year when the car is not there something wrong here is, in fact, are wrong line, and now the these lines into an optical fiber,
2, practice
first, when we open the hood of the time, only one optical fiber; a second, without the aging, failures occur, the phenomenon of short circuit, but the cost will be very high, basically we use local area network control system. The more the more high-end cars inside the CAN-BUS, there are two, three, four, of course, price is not the same, and now we see more than 25 million cars have this thing, do not underestimate this thing, in fact, he is a module that there are many switches, components, interfaces, if the time between the two modules to be connected, that only one optical fiber, the transmission speed, no problem, so the choice, first ask you this vehicle has no cAN-BUS is set, and if not, to ensure its technology, but also the cost of not up to standard, and therefore can not be called a good car.
