Abstract： |
A fuel battery distribution type controlling system CAN network communication method based on time triggering, which belongs to the fuel battery system network communication technology field. The present invention comprises a fuel battery system TTCAN network and a single chip electric voltage gathering TTCAN network; in the fuel battery system TTCAN network, the main controller can periodically transmit reference information to other nodes, the other nodes initiate the timer, and the triggering transmission is interrupted when the timer runs to the predetermined value of the corresponding time; in the single chip electric voltage gathering TTCAN network, after the single chip electric voltage statistic node receives the reference information from the main controller, the node transmits the reference information to the single chip electric voltage gathering board, the single chip electric voltage gathering board initiate the timer, and the triggering transmission is interrupted when the timer runs to the predetermined value of the corresponding time; the present invention also provides a compilation method of the message matrix as the system communication logic core. The present invention can avoid the network arbitration and conflict, improve the network security and timeliness, and simplify the network design process. |
