The utility model belongs to the field of the instrument, and relates to a debugging diagnosis instrument based on an embedding-typed system structure, and is used for the data display, the parameter calibration, the function commissioning and the malfunction diagnosis of the engineering equipment with a control system based on a CAN bus. The hardware of the instrument consists of a system main board and an interface board, which are designed according to an ARM chip HMS30C7202, wherein, the interface board is mainly provided with a power-source board and a keyboard interface board; the instrument information is displayed through an EL displaying screen, an instrument external interface is mainly provided with a CAN interface (five cores) and a RS232 interface (seven cores). The software of the instrument adopts micro C/OS-2 as a real-time operation system, and the development of a graphical user interface is based on a MiniGUI platform. The interface consists of a system configuration module, a control input module, a control output module, a sensing detection module, a data communication module and a parameter calibration module, which are relatively independent. The debugging diagnosis instrument integrates the functions such as the signal collection, the processing, the malfunction diagnosis, the network communication, etc. into a whole, thereby having the advantages of high performance, low power consumption, high speed, low electromagnetic radiation, electromagnetic interference resistance, etc.
