The application discloses a traffic adaptive safety switching control method and system, computer equipment and a medium, and belongs to the technical field of intelligent traffic, comprising the following steps: constructing a lattice fluid dynamics model, performing linear stability analysis to obtain a critical condition; periodically judging whether the current traffic flow state tends to be unstable based on the critical condition; when the current traffic flow state does not satisfy the critical condition or the traffic oscillation amplitude in the current traffic flow state exceeds a preset threshold, generating an adaptive safety switching controller enabling instruction; activating and running an adaptive safety switching controller based on road network geometric characteristics according to the adaptive safety switching controller enabling instruction; and feeding back the control signal as an additional adjustment term to the flow evolution equation of the lattice fluid dynamics model, so as to obtain a closed-loop control optimized lattice fluid dynamics model. The method improves the anti-interference ability, overall stability and driving smoothness of intelligent networked vehicle traffic flow in a mixed geometric road network environment.

The application discloses a kind of multi-pulse signal flexible drive adjusting device and method, belong to radio frequency power supply technical field, solve two-stage different pulse signals in switching process Conflict, leading to the problem of full switch tube conduction in power amplifier.In the device, multi-pulse generator generates multi-stage pulse signal;Switcher switches the pulse signal output by multi-pulse generator;During the switching transition of multi-stage pulse signal: switching enable controller, according to the level of pulse signal before and after switching, gradually generates pulse switching adjustment signal to control at least one of power, frequency output ramp gradually or gradually decrease;And according to the pulse switching adjustment signal generated gradually, gradually generate the control signal of power amplifier;The power amplifier of radio frequency power supply is based on the control signal of power amplifier to drive radio frequency power supply, and gradually correspond to adjust the output power and frequency of radio frequency power supply during the switching transition of multi-stage pulse signal.
