Where is the computer interface of Changan Ford?
As an exhaust emission monitoring system, OBD gradually expanded its control range in the later development. With the development of electronic sensors and vehicles, OBD brings all monitoring functions into its jurisdiction.
Computer data shows that OBD interface, as the communication interface of vehicle monitoring system, not only reads fault codes for vehicle maintenance, but also provides various working conditions data of vehicles. In addition to the data displayed by the on-board instrument, there are actually many data recorded by the driving computer, including many vehicles without the driving computer display screen. In fact, data such as fuel consumption record, battery voltage, air-fuel ratio, throttle opening and knocking times are recorded in the system. However, due to factors such as price configuration, manufacturers will remove the driving computer and display it on vehicles with low configuration, so users can't refer to these useful data.
Connect to the OBD interface of the vehicle through a dedicated data line. Reading out the data and displaying it on the matching display screen is basically equivalent to installing a driving computer display screen. Under normal circumstances, the connecting cable can be plugged into the OBD interface all the time, and only the display screen needs to be fixed, so the owner can choose the data to be displayed by himself. Another product form is wireless OBD interface adapter+smart phone software. This OBD port reader matched with mobile phone is similar to a single chip microcomputer with wireless communication module. The data read by the OBD interface is transmitted to the smart phone through Bluetooth or Wifi, and then presented to the user through the software of the mobile phone.
