Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment one：
As shown in Figure 1, a kind of gate intelligent controlling device of the present invention, including sequentially connected power module 1,
Controller 2, motor driving 5 and motor 6 further include by the gate 7 of the control switch of motor 6, for feeding back 6 electric current of motor letter
Number Hall sensor 3, the tachometer of measuring 4 for feeding back 6 tach signal of motor, Hall sensor 3, tachometer of measuring 4 divide
It is not electrically connected between controller 2 and motor 6, controller 2 is automatically real by the speed of 6 rotation speed change of electric current and motor of feedback
Now to the intelligent control of gate 7.The gate intelligent controlling device is set to train door entrance, corresponds respectively to track
Uplink and downlink both sides；Several are arranged along subway platform length in the gate intelligent controlling device, and are electrically connected to by bus
Central monitoring control panel 9.Wherein, two kinds are divided into the case where gate 7 is obstructed, one is the limbs and gate that have object or people
7 physical contact, another kind be when subway running interval is compressed to 2 minutes or so, and the wind speed of 7 wind-tunnel of gate is larger, it is larger
Windage pressure gate 7 can be caused not close in time.By gate intelligent controlling device, it is which that can tell on earth
A kind of situation leads to being obstructed for gate 7, once the second situation occurs, so that it may effectively to take the processing method that is hampered, from
And reach the normal switch to gate under dynamic pressure 7.
As shown in Figure 1, Fig. 2 is a kind of intelligent control principle of intelligent platform controlling device for doors disclosed by the embodiments of the present invention
Figure, the Hall sensor 3 and tachometer of measuring 4 provide two close cycles negative-feedback signal as can be seen from Figure 2, for realizing institute
The automatic adjustment for stating motor can effectively promote the adjusting stability of intelligent control platform door by the design of two close cycles, into
One step, it is provided with current regulator between controller 2 and motor driving 5, for regulating and controlling between controller 2 and motor driving 5
Electric current.It is additionally provided with speed regulator between controller 2 and motor driving 5, for regulating and controlling 6 rotating speed of motor.
Preferably, the current feedback signal and the speed feedback signal show difference when windage and physics are obstructed,
The change rate of electric current and rotation speed change that physics is obstructed is significantly higher than windage.For gate 7 by when windage pressure and platform
It is slowly varying that the maximum difference that 7 direct physics of door are obstructed is that the former can cause the motor 6 of driving gate 7 to occur, and object
The motor 6 of driving gate 7 can occur to change faster when reason touches gate 7, i.e. moment allows for the stopping turn of motor 6
It is dynamic, can be parameter change rate by detect 6 change procedure of motor, so that can according to the difference of the variation therefore
Effectively to automatically control out the influence that windage closes gate 7.When windage effect gate 7 is closed, windage is to load electricity
The influence of stream is the slow increase of moment, is slowly to decline for 6 velocity of rotation of motor；And the influence to load current that is hampered
It is to increase long-term moment, but is that unexpected decline even stops triggering and block mechanism for speed.Therefore, Hall can be utilized
Sensor 3 detects 6 electric current of motor, and tachometer of measuring 4 detects 6 rotating speed of motor, and these digital signals of detection are transmitted
Into controller 2, controller 2 regulates and controls current regulator and speed regulator, by motor driving 5 so that motor
6 can make opposite action, i.e., when encountering windage pressure so that 6 electric current of motor becomes larger, and 6 rotating speed of motor is promoted, to support
Influence of the windage that disappears to gate 7.Wherein, what the Hall sensor 3 detected is the input current of the motor 6, described double
Close loop negative feedback signal includes current feedback signal and speed feedback signal, and current feedback signal is faster than speed feedback signal and arrives
Up to controller 2.
Preferably, motor 6 is brush DC synchronous motor 6, and motor driving 5 includes dual H-bridge driving chip.Further,
Tachometer of measuring 4 includes magnetoelectric tachometer, and the magnetoelectric tachometer will directly can pass the data of 6 rotation speed change of motor
It is defeated by controller 2.Therefore, when windage effect to gate 7 is closed, brush DC can be driven by dual H-bridge driving chip
Synchronous motor 6 is quickly made a response, and brush DC synchronous motor 6 can realize stable, frequent conversion rate.
Further, controller 2 includes double PLC controls chips, and the stabilization of control is improved by the control chip of redundancy
Property.Since 6 electric current of motor is after the transformation of complex mathematical current-mode, current phasor space is transformed to 2 dimensions from 3 dimension dynamic models
Then static models are sampled according to (50ms~250ms) in certain period of time, controlling chip by PLC calculates 6 electricity of motor
Flow threshold average.The slow increase of the moment of 6 electric current of motor becomes insensitive to average threshold judgement in this way under windage, therefore
It is impacted smaller, but to be hampered load when 6 electric current of motor long-term moment increase it is very sensitive, electric current average threshold is drawn by moment
Height, once and speed stop triggering and block mechanism also triggering is hampered judgement indirectly.Similarly, in the judgement to rotating speed, and
Variation of the motor speed in certain period of time is obtained by tachometer of measuring 4, and controlling chip by PLC detects 6 rotating speed of motor
The change rate of variation, because in windage pressure and the change rate for the lower motor speed variation that is hampered in the presence of very difference greatly, therefore,
Motor 6 can make regulation and control automatically, to realize the intelligent control of gate 7.
Embodiment two：
As shown in figure 3, the layout structure schematic diagram of 7 control device of intelligence gate disclosed by the invention AT STATION, from this
The control system at the entire station of it can be seen from the figure that, wherein each gate 7 for a gate intelligent controlling device,
So as to make the auto-control of stability and high efficiency in the case where encountering windage, wherein the system includes mainly signal system
8, central monitoring control panel 9, station composite control apparatus 10, wherein signal system is electrically connected to central monitoring control panel 9, vehicle
Composite control apparatus 10 of standing is electrically connected to central monitoring control panel 9, and the central monitoring control panel 9 can be realized to entire station
Integral monitoring and adjusting, belong to first order regulation and control unit, be in an emergency lower with priority acccess control to go out inside station
Each point of regulator control system and device, for example, in the case where being in an emergency, central monitoring control panel 9 can be to the closing of gate
And opening, and do not influenced by the gate intelligent controlling device, reach always to regulate and control entire station with this, wherein
In 7 part of corresponding gate, and there is the branch of regulation and control, corresponds respectively to uplink and downlink platform control panel, it is preferable that in described
The electrical connection of centre monitoring control panel 9 and platform control panel, for being uniformly controlled several intelligent platform controlling device for doors.The station
The artificial master control to gate 7 may be implemented in platform control panel.Wherein, the uplink and downlink of subway are both provided with N number of gate intelligence
