| For tunnel ventilation monitormg system with high safety and reliability, information transmission distance and
main monitoring network node, the tunnel ventilation control system was put forward based on CAN bus technology. The
hardware structure of control system was designed based on CAN bus technology, and the principle of smoke detection
and temperature detection were introduced. The ventilation system of monitoring nodes based on CAN bus was designed.
The industrial PC and CAN bus commumcation interface adapter card were carried out. The system of the main program
and event inspection and handling subroutine flow chart were realized. Application results show that the system has a
transmission distance and mam monitoring network nodes, greatly improving the real-time performance and reliability of
the system. |
