Abstract

The invention discloses diagnosis equipment, a diagnosis request processing method and a computer readable storage medium. The diagnosis equipment comprises a controller module, a transceiver module and a connection control switch module, wherein one end of the controller module is connected with a host, the other end is connected with one end of the connection control switch module, the other endof the connection control switch module is connected with one end of the transceiver module, the other end of the transceiver module is connected with an automobile diagnosis system, the controller module is used for receiving a diagnosis request sent by the host, a first connection instruction is determined according to the diagnosis request, the first connection instruction is transmitted to the connection control switch module, a target transceiver is determined by the connection control switch module from the transceiver module according to the first connection instruction, the target transceiver and the controller module are controlled for communication, after communication, the diagnosis request is transmitted by the controller module through the target transceiver to the automobilediagnosis system. The diagnosis equipment is advantaged in that multiple types of CAN protocols can be supported, and protocol compatibility is improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a diagnosis device, a diagnosis request processing method and a computer-readable storage medium. Background technique [0002] Controller Area Network bus (Controller Area Network, CAN) is a serial communication protocol bus for real-time applications, which can solve the problem of data exchange between many measurement and control components in modern vehicles. The CAN protocol can be used for communication between various components in a car, replacing expensive and bulky distribution wiring harnesses. [0003] With the popularity of cars, car maintenance problems also follow. At present, most cars will be equipped with a car diagnostic system, which can record diagnostic data when the car fails. When maintenance personnel perform fault detection on automobiles, they usually select diagnostic equipment to obtain automobile diagnostic data from the automobile dia...
