Vehicle-mounted OBD device used on OBD diagnosis seat and communication system

Abstract

The invention discloses a vehicle-mounted OBD device used on an OBD diagnosis seat and a communication system. The vehicle-mounted OBD device comprises the OBD automobile diagnosis seat, an automobile condition data acquisition interface circuit, an MCU control module, a USB interface and a mobile phone bracket with a charging port. The vehicle-mounted OBD device is communicated with the smart phone through a USB, the cost for a Bluetooth module and a WiFi module is saved, data transmission stability is improved, the user can conveniently use the mobile phone on an automobile through the mobile phone bracket with the charging port, the automobile is connected with the smart phone through the USB interface and a lead, and the electric energy demand of the automobile owner using the smart phone for a long period of time is met. After the smart phone is connected with the vehicle-mounted OBD device, the phone APP automatically detects mobile phone connection, and an OBD protocol can be started in advance for scanning. After the mobile phone of the user is connected and the phone APP is started, the vehicle-mounted OBD device can quickly display a result compared with common OBD devices, efficiency is improved, user experience is improved, the attractiveness of a traditional vehicle-mounted OBD device to the automobile owner is improved, and dependency of the user to a product is also greatly improved.

[0002] At present, with the rapid development of IT technology and mobile Internet technology, the traditional automobile market is also facing various opportunities and challenges. The Internet of Things technology represented by the Internet of Vehicles has developed rapidly in the past few years; in the automobile market Due to the natural connection between the car diagnostic technology and the car OBD diagnostic seat, many industry experts even believe that the car OBD is the only entrance to obtain car data in the Internet of Vehicles. Under this situation, various car Box, car OBD terminal, they are all directly installed on the car OBD diagnostic seat, using traditional car diagnostic technology to read the vehicle condition information, such as: whether there is a fault, the current engine speed and water temperature, etc.; and traditional OBD diagnosis The biggest difference is that they do not have an LCD display, but directly transmit the collected car data to the user's mobile phone through Bluetooth or WiFi, and display the data with the help of the APP on the mobile phone, although these OBD terminals can also realize the car OBD diagnosis function, But for car owners, because the chance of car failure is very small, long-term installation on the car is not very attractive to car owners, so it lacks user stickiness. The market has proved that such products have not been recognized by users. , Individual car owners are not willing to pay the bill. Market research shows that even if some car owners who are willing to try new things are willing to use them, they will basically remove them from the car after using them for a period of time.
