Multi-rotary-transformer decoding device based on CAN bus

Abstract

The invention discloses a multi-rotary-transformer decoding device based on a CAN bus, and the device comprises a plurality of rotary transformer wiring terminals; a collection circuit which is connected with each rotary transformer wiring terminal; a decoding circuit connected with the collection circuit; a CAN bus transmitting circuit connected with the decoding circuit; a first CAN communication interface which is connected with the CAN bus transmitting circuit and the corresponding CAN bus. According to the invention, the analog signals outputted by rotary transformers connected with the plurality of rotary transformer wiring terminals are converted into corresponding angles through the decoding circuit, thereby achieving the decoding of the rotary transformers at the same time. The angles are converted by the CAN bus into the corresponding CAN bus information, and the CAN bus information is transmitted to the CAN bus connected with a first CAN communication interface. The device employs the CAN communication for transmitting the decoding information, thereby solving an interface problem of the communication between the rotary transformers and engineering mechanical equipment,and reducing the measurement cost of multiple rotation angles.

Description

technical field [0001] The invention relates to the technical field of resolver signal conversion, in particular to a multi-resolver decoding device based on a CAN bus. Background technique [0002] In the field of construction machinery, the position detection of the rotary joint often uses a rotary encoder or a decoding device using a single resolver to measure the angle. However, when multiple rotation angle measurements are required in the equipment, if a rotary encoder or a single resolver The decoding device will make the measurement cost higher, and the installation space is larger; and the measurement results obtained by the rotary encoder or the decoding device of a single resolver in the prior art are often not directly transmitted to the corresponding construction machinery equipment. Bad for user experience. [0003] Therefore, how to provide a decoding device that can decode multiple resolvers at the same time and output decoded information in a bus output mode...
