The invention relates to an
electromagnetic compatibility and
radio frequency coexistence framework, and belongs to the technical field of vehicle-mounted display and
electromagnetic compatibility. The device comprises a display module and a
control system which are arranged outside a vehicle body, the
control system is provided with a cooperative
control unit, an
electromagnetic interference suppression module and a running state monitoring and adjusting module to form a closed-loop framework, and the closed-loop framework is used for dynamically managing display signals, power and a
time sequence in the running process of the vehicle, suppressing conduction and
radiation interference and controlling the running state of the vehicle. And the coexistence performance of the external display and the vehicle-mounted
radio frequency system is ensured, and the
electromagnetic compatibility regulations are met. Further, the
system comprises an integrated topology unit, a coexistence monitoring unit and a
strategy execution unit, driving
time sequence shaping,
backflow path constraint and power supply
ripple shaping are achieved, and when interference exceeds a threshold value, the
system is switched to a controlled display state. A shielding-grounding-filtering three-in-one
layout and a driving
time sequence shaping unit can be adopted. According to the invention, the safety and reliability of external display in the aspects of electromagnetic compatibility,
radio frequency coexistence and service
life management are ensured.
