Intelligent transformer coil temperature measuring mechanism based on CAN bus

The invention discloses an intelligent transformer coil temperature measurement mechanism based on a CAN bus, which is a novel data transmission mechanism with a single bus and multiple modules connected, and is composed of an intelligent transformer coil 1, an FPS intelligent sensor 2, a repeater 3, a CAN bus I4, a CAN bus II5, a CAN bus repeater 6 and a CAN base station 7. The mechanism comprises a data sending module and a data receiving module, the modules communicate through data and instructions, the base station and the slave station can be regarded as a node on a CAN bus, information can be transmitted between the nodes, and each node can filter information to agree to receive or refuse to receive. According to the invention, a CAN bus transmission protocol is utilized, an original single optical fiber transmission mode is changed, and the mechanism has the advantages of multiple parameters of a collected sensor, large bus data volume, strong mechanism anti-interference capability and the like. 本发明公开了
