Abstract

The invention discloses a DSP-embedded-system-based multi-bus integrated control apparatus comprising a power supply module, a DSP controller, a CAN bus matching module, an AD acquisition module, a 1553B driver circuit and a relay control module. The apparatus is used for receiving a 1553B bus instruction of a control system and executing an instruction motion, receiving a CAN2bus instruction of a testing system and executing the instruction to test all single machines, carrying out back testing to realize real-time testing of instruction execution states of the multi-bus integrated control apparatus and other single machines. Using the multi-bus integrated control apparatus disclosed by the invention, the function of real-time feedback of states of all single machines to a control system and a testing system is realized. The multi-bus integrated control apparatus has characteristics of high integration degree, high automation degree, small size, high reliability, and good real-time performance. Problems that the existing integrated control device can not test the device itself and large space is occupied can be solved.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and more specifically relates to a multi-bus integrated control device based on a DSP embedded system. Background technique [0002] At present, both 1553B bus and CAN bus are widely used, with high reliability and strong anti-interference ability. Compared with the CAN bus, the cost of the 1553B bus is higher, and the 1553B bus is used to transmit control command information in fields with very high reliability requirements such as aviation and aircraft. However, due to space constraints and limited test signal interfaces in related fields, the single-machine test is cumbersome, and many auxiliary test equipment need to be deployed to carry out; and it cannot be self-tested; some signals cannot be tested without external connections. Contents of the invention [0003] Aiming at the above defects or improvement needs of the prior art, the present invention provides a multi-bus compre...
