2. a kind of cage overspeed protective device and its guard method based on radar velocity measurement according to claim 1, special
Sign is：Include the following steps：
Step A):Initially enter initialization, cage normal work；
Step B):Radar micro-wave module in radar velocity measurement sensor is responsible for transmitting and receives radar microwave, and to emitting and connecing
It receives wave and carries out the difference frequency signal that Frequency mixing processing acquires output, this signal is supplied subsequent conditioning circuit to carry out by STM32 microcontrollers
Data analysis is compared with the velocity amplitude that processing obtains with cage speed limit Vs：
a):When being less than cage speed limit Vs, the motor of cage normal operation, overspeed protection self-locking device does not work.
b):When more than cage speed limit Vs, step C is executed).
Step C)：STM32 microcontrollers control double relay and are operated clockwise to control motor, and gear is transported downwards along rack
It is dynamic, make angle between head rod, the second connecting rod under the first supporting steel plate structure function of overspeed protection self-locking device
Reduce to drive the distance between the second brake pad on the first brake pad and the 4th connecting rod in third connecting rod to reduce, when
When brake pad touches cage guide, self-locking is realized under the gravity of cage and overspeed protection self-locking device, holds cage guide tightly so that
Cage is braked immediately.
Step D):Cage braking completely is when remaining static, and after maintenance is errorless, STM32 microcontrollers control double relay
Control motor rotates in an anti-clockwise direction, and controls the angle of gear rotation to be restored to initial position, cage works on.
Step E):When cage uplink：
c):When being less than cage speed limit Vs, the motor of cage normal operation, overspeed protection self-locking device does not work.
d):When more than cage speed limit Vs, step F is executed).
Step F)：STM32 microcontrollers control double relay and are counterclockwise operated to control motor, and gear is transported upwards along rack
It is dynamic, the folder between the 5th connecting rod, the 6th connecting rod is made under the second supporting steel plate structure function of overspeed protection self-locking device
Angle reduces distance between driving the 4th brake pad on the third brake pad and the 8th connecting rod in the 7th connecting rod and reduces,
When brake pad touches cage guide, self-locking is realized under the effect of inertia of cage and overspeed protection self-locking device, is held cage guide tightly, is made
Cage is obtained to brake immediately.
Step G):Cage braking completely is when remaining static, and after maintenance is errorless, STM32 microcontrollers control double relay
Control motor rotationally clockwise, the angle of control gear rotation is restored to initial position, and cage works on.
