The utility model relates to an intelligent parking stall lock with sound and light warning and voice prompt belongs to parking stall lock technical field, including base, the top hinged cover of base is fixedly installed with the side of cover and is pasted board, the inner bottom wall fixed mounting of base has control box, the inside of control box is provided with sound and light warning subassembly, sound and light warning subassembly includes the infrared detector fixed mounting at the top of control box. This intelligent parking stall lock with sound and light warning and voice prompt, through setting infrared detector at the top of control box, setting ultrasonic detector on the front of base, through infrared detector and ultrasonic detector to the detection of vehicle, when cover does not descend, when detecting that vehicle is close, voice horn rings, through the voice prompt driver's attention, warning light flashes, through the light prompt driver's attention, prevent driver to continue driving vehicle and the collision of intelligent parking stall lock.

The invention discloses an ultrathin industrial power supply with PWM and constant current dimming functions, which comprises an input and rectification module, a power factor correction module, a dimming instruction module, a pulse modulation module and an output module, and is characterized in that the pulse modulation module comprises a main power switch, a PWM controller and a protection sub-module; the protection sub-module comprises a temperature detection unit, an oscillation detection unit, a collaborative judgment and control unit and an execution feedback unit, and the protection sub-module is used for collaborative temperature oscillation protection in the dimming process of the industrial power supply. The protection submodule is arranged and comprises a single-factor circuit protection group, a temperature detection unit and an oscillation detection unit, effective overtemperature, overload and overvoltage protection is carried out in the working process of the power supply, temperature and oscillation signals are subjected to collaborative analysis, and the purpose of temperature and oscillation collaborative protection is achieved; oscillation of the power supply due to temperature and load influence is avoided, light flash and self-oscillation phenomena are prevented, the dimming quality is improved, and the service life of the power supply and the load is prolonged.

The application discloses a kind of manual single shutter blowout preventer anti-lifting safety device, it is when the shutter of manual single shutter blowout preventer is completely opened, shutter shaft end surface push lever (3), press down pneumatic switch valve (2) spool, the air inlet of pneumatic switch valve (2) is communicated with the air outlet, combined valve gas supply is normal, can be lifted oil pipe, alarm (BJ) light does not bright, when manual single shutter blowout preventer has not completely opened, shutter shaft end surface (2301) fails to push lever (3), pneumatic switch valve (2) spool is extended under the action of spring, the air inlet of pneumatic switch valve (2) is not communicated with the air outlet, the air outlet is communicated with exhaust port, cut off combined valve gas supply, winch clutch has no air pressure and can not be hung, can not be lifted oil pipe, simultaneously, alarm (BJ) light flashes.The application realizes the function of manual single shutter blowout preventer anti-lifting, and prevents the occurrence of safety accident.

The invention discloses a video editing processing method based on artificial intelligence, and relates to the technical field of video processing, and the method comprises the following steps: building a light flash feature description rule for an illumination rapid jump scene, converting each brightness sudden change in a video frame into a light flash event, forming the continuous flash events into a flash event sequence to construct a flash track; and screening a time slice with the maximum brightness change amplitude on the light flash track, extracting a slice with the character expression action kept stable from the time slices, and taking the screened slice as an emotion reference slice to form an emotion baseline. According to the method, through compression of a light flash track, an emotion baseline and an emotion curve, emotion change expression is closer to a real state of a person, and emotion interference caused by illumination jump is weakened; and meanwhile, self-adjusting editing rhythm control is added into the smooth emotion band, so that the rhythm can be adjusted along with the emotion change and the illumination disturbance is avoided, and the rhythm continuity and the emotion expression accuracy of a piece are improved.
