The working process of potential energy speed-controlling device of the present invention:
1, conversion process of energy: human body gravitional force G pulling traction sheave rotates ω, traction sheave drives the rotation of damping Capstan rotor, relative motion produces induced potential e between epitrochanterian permanent magnet and stator armature, induced potential e produces induced current I in C/LOOP, induced current I produces braking torque M between the rotor air gap, the effect of this braking torque M balancing gravity potential energy G makes the traction sheave rotational speed omega keep constant relatively.
2, feedback procedure: when load torque G＞braking torque M → magnetic damping towing machine rotational speed omega ↑ → electro-motive force e and loop current I ↑ → braking torque M ↑ → make braking torque M ≈ load torque G enter steady-state operation.When load torque G＜braking torque M → magnetic damping towing machine rotational speed omega ↓ → electro-motive force e ↓ and loop current I ↓ → braking torque M ↓ → make braking torque M ≈ load torque G enter steady-state operation.
3, real-time control process: by Hall 42 tach signals on the real-time collection magnetic damping towing machine 16 and current sensor 39 output current signals, utilize to encircle in (electric current) and revise control wave PWM dutycycles with two closed loop pid control algorithms of (rotating speed) outer shroud, adjust the make-and-break time of power switch pipe, control magnetic damping towing machine braking torque, reach this and load on and slow fall dynamical equilibrium in the process, as shown in figure 14.
4, running process of elevator: as shown in figure 12, counterweight lock rope pincers 25A, 25B are in unlocking condition, and counterweight hoist ropes 8 shuttles back and forth and mistake; Magnetic damping towing machine 16 is braked the device locking, potential energy lock rope pincers 26 locking potential energy transmission ropes 20.When electric life controller drove car, car hoist ropes and counterweight hoist ropes 8 affected car 4 and counterweight 5 along guide rail operation in opposite directions up and down separately, are as good as with conventional lift running condition.Storage battery connects AC charger by commercial power charged when the elevator state moves.
5, escape operational process: as Figure 13 and shown in Figure 11, when fire takes place the fireman's switch 22 of floor calling device 23 send out an emergency signal → the capturing unit CAP1 of DSP microprocessor wakes damping controller 17 up and is in major state; At first the mouth J0 transfer relay 45 of damping controller 17 to dc charger, J3 out-put supply switching signal, supply convertor 48 is switched on the power end daughter board of electric life controller, the control command of mouth J4, the J5 of damping controller 17 output subsequently: 1. instruct electric life controller that a car is stopped to ground floor, another car stops to the floor that sends trumpet call, forms diff-H; 2. the drg of two elevator traction machines of the mouth J1 output signal of damping controller 17 locking, locking counterweight lock rope clamp 25; 3. car to be received sends the ready signal ST that closes the door (escape personnel of fire floor enters car and presses the interior descending button of car); 4. potential energy lock rope pincers 26 and magnetic damping traction machine brake are opened in the mouth J2 of damping controller 17 output, high-order car under the effect of human body gravitional force slow fall operation and heavily loaded car potential energy converting and energy become electric energy feed back in the accumulation power supply device storage battery or with the consumption of heat energy form on resistance.Damping controller 17 at the uniform velocity descends heavily loaded car by PID control resistance braking torque, and the unloaded car of the another of counterweight is thus lifted to the coordination height each other; Wait to receive that 3., 4. car ready signal repetitive instruction that energy disperser 24 sends, continues to transport with the floor trapped personnel, realize passive back and forth slow falling.
When a plurality of floor calling devices are stirred fireman's switch, damping controller by the order of queuing successively or the order repetitive instruction of press the unloaded car parking of the adjustment floor that the fire-fighting and rescue personnel are provided with 1., 2. operate, but assurance has the floor of a car at ground floor or escape unharmed, receives that 3., 4. execution command behind the car signal in place realizes the function of any floor rescue.
