Description
Technical field
The present invention relates to controlling and regulating system field, the control method of especially a kind of power-assisted switch sliding door that tests the speed and control
System, and the vent cabinet using the control system.
Background technology
Vent cabinet is an indispensable part in laboratory ventilation design.In order to make laboratory worker not
Suck or swallow should have in the chemical substance and organism, laboratory that some are poisonous, can causing a disease or toxicity is unknown it is good
Ventilation.To prevent the absorption of some steams, gas and particulate (smog, coal smoke, dust and aerosol), polluter must use ventilation
Cabinet, ventilator cowling or the method for local ventilation remove.Traditional vent cabinet is generally controlling motor just using button and floor push
Reversion, so that the automatic lifting of vent cabinet sliding door is controlled, when controlling motor using button or floor push, when user is to sliding door one
During a thrust of (or downward) upwards, the impact that motor power-assisted starts or stops is larger, and user experience is poor.Therefore need to design
The control method of sliding door automatic lifting above and below a kind of more preferable power-assisted vent cabinet of effect.
A kind of vent cabinet sliding door is disclosed in the Chinese utility model patent file of Patent No. CN204386334U certainly
Dynamic lifting gear, including for fixing ventilation cabinet frame work, the sliding door on frame of sliding door and for driving sliding door
The cable wire of lower movement；Motor is provided with ventilation cabinet frame work；Motor shaft end is connected with encoder；The start-stop of motor is by watching
Take controller control；Encoder provides servo controller by the steering of motor shaft and performs signal, so as to control electric motor starting；Even
The cable wire for connecing sliding door is arranged on motor shaft, and it is that cable wire drives motor shaft to rotate that sliding door, which moves up and down,；Cable wire also passes through pulley blocks
It is connected with the balance weight for balancing sliding door weight；Position-detection sensor is provided with the top of sliding door.The utility model uses
Motor steering detection device, by programme-control, it starts speed and displacement distance, plus location determination, as long as gently one carrying, and electricity
Machine and then starts, and steadily reaches designated position；Close the door equally toward next drawing, motor and then starts the steady lowermost position that reaches and puts.
Specifically, vent cabinet carries out position detection first after being powered, and sliding door turns first to closed mode (when encountering barrier
When can be automatically stopped downlink)；When the external world is (downward) mobile upwards to sliding door, door is rotated forward (anti-by cable wire drive motor shaft
Turn), encoder provides servo controller by the steering of axis and performs signal, so as to control electric motor starting, whole action is relatively more flat
Surely (only need slight rotation just can obtain signal), the speed and displacement distance of motor control SERVO CONTROL by PLC programmings
Device, so as to control motor.The utility model patent file is by detecting the position of sliding door, and by programme-control, it starts speed and shifting
Dynamic distance, it is not specified that detailed control process, can not obtain good practical function.
A kind of intelligent ventilating cabinet is disclosed in the Chinese utility model patent file of Patent No. CN204747039U, is wrapped
Include cabinet, adjust door and ventilation duct, adjust door and be installed in cabinet, ventilation duct is installed on the top of cabinet, is installed in ventilation duct
There is variable air rate valve, displacement sensor is provided with the inner side on cabinet top, for monitoring the height change of the adjusting door, and
The position signal of the adjusting door is sent to vent cabinet monitor, by opening for vent cabinet monitor control variable air rate valve
Degree.The intelligent ventilating cabinet of the utility model, can according to adjust door highly automated adjusting vent cabinet face wind needed for ventilation quantity,
Reach the constant accurate control effect of vent cabinet face wind speed, which also has the multiple-working modes such as energy saving, delay, protecting
Demonstrate,prove more environmentally friendly while exhausting effect；In addition, the adjusting door energy automatic lifting of the vent cabinet, easy to operate.
Wherein, transmission device is also equipped with the upper inner of the cabinet, the lifting for adjusting door is driven by transmission device,
The bottom of cabinet is provided with adjusting door switch, which, which is divided into, rises floor push and decline floor push, passes through
Door switch is adjusted to control the working status of transmission device, so as to realize the automatic lifting for adjusting door.The utility model is logical
The position signal of displacement sensor detection door is crossed, the automatic lifting of door is driven by transmission device.But position signal is not associated with to control
Transmission device processed, so as to help door to carry out automatic lifting, so being not reaching to more preferable control effect.
From above-mentioned patent document, current vent cabinet switchs sliding door mostly by detecting the position height of sliding door, root
The automatic lifting of sliding door is controlled according to the changing value of position, or by detecting the moment values added in sliding door, according to motor
Working power control the automatic lifting of sliding door, both approaches, which cannot reach, is accurately controlled effect, be also unfavorable for leading to
Wind cabinet is energy saving.
