CAN bus dynamic configuration device and method

Abstract

The invention provides a CAN bus dynamic configuration device and method. The CAN bus dynamic configuration device comprises a bus printed circuit board and at least one connector assembly, wherein the bus printed circuit board covers and seals with other electronic devices in an integrated mode, a CAN bus chip is arranged on the bus printed circuit board and comprises a plurality of setable pins, and each setable pin is connected with a power supply end through a pull-up resistor; the connector assembly is provided with a plurality of mutually electrically isolated connection ports and at least one grounded port, one connection port is correspondingly connected with one setable pin, and the grounded port is connected with the ground; the connection ports connected with the setable pins are electrically connected with the grounded port, thereby implementing 0 resetting of the setable pins, or the connection ports connected with the setable pins are electrically isolated from the grounded port, thereby implementing 1 resetting of the setable pins; and wire jumpers inside the connector assembly reset related position to be 0 or 1 so as to implement the configuration of an ID identifier of a CAN bus node on the premise that a single chip computer does not open a cover, so that an effect of flexible configuration of the ID identifier of the CAN bus node is achieved.

Description

technical field [0001] The invention relates to the field of aerospace communication, in particular to a CAN bus dynamic setting device and method. Background technique [0002] At present, the ID setting of the CAN bus node is pre-set when the stand-alone is developed. However, due to the needs of spacecraft development, some types of spacecraft on-board equipment are realized by selecting shelf-type products to shorten the development time of a single machine, and the modification of the ID of the spacecraft on-board equipment requires a single machine to open the cover. However, to open the cover of a stand-alone machine, a series of approval procedures must be passed, and the functional performance of the product must be re-tested at the same time, which limits the rapid use of the product. Therefore, how to ensure the rapid use of the product without opening the cover of the stand-alone machine has become a problem that needs to be solved urgently. Contents of the in...
