OBD what is it?

I believe that some of the car modification of a friend will guess the author said that the OBD, indeed, if you want to plug the smart devices, OBD interface is now more mature is a choice. OBD is the abbreviation of the English Diagnostic On-Board, Chinese translation for the vehicle diagnosis system". OBD device can monitor for multiple systems and components, including engine, catalytic converter, particle trapping device, oxygen sensor, emission control system, fuel system, EGR.

So how does OBD work? OBD is connected to the electronic control unit (ECU) through various kinds of information related to the emission, and ECU has the function of detecting and analyzing the related faults. When an emission fault occurs, the ECU records the failure information and the related code, and sends out the warning to the driver through the fault lamp. ECU through the standard data interface, to ensure that the fault information access and processing.

ECU (Control Unit Electronic) electronic control unit, also known as "traffic computer", "car" and so on. From the use of speaking, it is a special computer controller for automobile. It is the same as the ordinary computer, by the microprocessor (CPU), memory (ROM, RAM), input / output interface (I/O), analog digital converter (A/D) and plastic, drive and other large scale integrated circuit. With a simple words to describe, ECU is the car's brain.

What can OBD do?

Since OBD can monitor the situation of different parts of the car, so naturally, whether it is the sale or the owner, all want to be able to achieve through the OBD hardware to monitor the operation of the various parts of the car. Currently available on the market there are two types of products based on the OBD interface, one is through a dedicated data lines connected to the vehicle OBD interface. After the data is read out through the software, display to the supporting display, the basic is equal to the installation of a driving computer screen for data monitoring.

The other approach is the wireless OBD interface adapter + smart phone terminal software. The mobile terminal with the OBD port reader is similar to a joined the wireless communication module of MCU, through Bluetooth or WiFi the OBD interface to read the data transmitted to a smart phone terminal, through the mobile terminal software was dedicated to the user. In contrast, this approach will be more likely to have the feeling of automotive technology, after all, this is the main effect of the linkage of smart devices and mainstream.

Because reading the body of different data, so for different aspects, these data can have a different role. For individuals, to know better body condition to better maintenance vehicles (although this in domestic now the car environment can correctly deal with fewer people and less), even for the car of the people is an important power.

What's the meaning of OBD?

OBD, as an important interface of the traditional auto industry, has a key role in promoting the development of automotive technology. However, OBD interface itself is not a car technology and the interface, and now the application is only based on the results of the operation of the OBD can be derived. When the parties have entered the field of automotive technology, the use of OBD interface, the curve of the country's influence gradually weakened.

On the other hand, due to the large number of startups using OBD interface approach intelligent auto parts, in view of the characteristics of the OBD interface, so based on OBD smart car hardware market development is still at a relatively early stage. For the start-up team, the OBD interface is easy to use, but the industry's good and full development, or need to have a certain benchmark to imitate.

However, for most still in driving traditional car owners, rational use of the OBD interface to experience the charm of science and technology in the car, it is a feasible practices. Because the relationship between the OBD and ECU has been more mature, so the product has a certain reliability and availability. For the favorite car technology, or want to further understand the state of the car for the young car owners, the price of moderate function comprehensive OBD equipment is a good choice.

May read the above introduction, the OBD interface for most of the owners is still ran X and things. However, the author believes that this article friends attention, except small part that the author is wrong studios outside, most of them are in car age, and want to play some tricks of friends. Since digital is unconsciously influence the lives of these friends, so why not try into the unlimited potential of field? Change is the beginning of a constant trial, even if there are enough mice.
