Description
Technical Field
The invention relates to the field of control of subway equipment, in particular to an intelligent control device for a platform door.
Background
The subway platform door system is arranged at the edge of the platform, is symmetrically arranged towards two ends of the platform by taking the center line of an effective platform as the center, separates a station track area from a platform area, adopts full-height closed platform doors for underground stations, and adopts half-height platform doors for overhead stations. Along with the extension of subway operation line, the subway passenger flow is constantly increased, and the continuous increase of subway operation line driving density has appeared when normal operation, and the totally high closed platform door of partial station is obstructed, leads to stopping the train and can't go out according to the plan, and then influences the condition of normal operation. Particularly, the situation that the doors of the platform door are blocked at a plurality of stations of a running line during a peak period influences the departure interval, so that passengers at the platform are detained, and great pressure is brought to the operation.
In the subway design specification, the door closing force of the platform door is definitely smaller than 150N so as to prevent passengers from being injured by the door in the door closing process, so that the traditional control system only considers the resistance influence generated by self weight when designing the motor output, and the door closing force is smaller than 150N under the condition that the resistance generated by dynamic wind pressure in the subway environment is not considered. When the platform door is blocked when encountering an obstacle, the door operating mechanism senses that the obstacle exists and releases the door closing force, the door is closed again after stopping for 3 seconds, and the door is closed repeatedly for three times if the door is still blocked, so that the door is fully opened to be treated. However, in the case of wind pressure, since the wind pressure value is varied at every pass in and out, and is uncertain, the platform door cannot be closed when the dynamic wind pressure acts on the door body. However, when the output force of the motor is set to be too large due to the change of the wind pressure value, the door closing force can be increased to hurt passengers under the condition of no wind pressure. Therefore, it is one of the major difficulties encountered in the current platform door systems to ensure the normal closing of the platform door and to meet the door closing requirements under such dynamic wind pressure conditions.

Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Embodiment one:
as shown in fig. 1, the intelligent control device for the platform door comprises a power module 1, a controller 2, a motor drive 5 and a motor 6 which are sequentially connected, and also comprises a platform door 7 which is controlled to be switched by the motor 6, a hall sensor 3 for feeding back a current signal of the motor 6, a rotation speed measuring instrument 4 for feeding back a rotation speed signal of the motor 6, wherein the hall sensor 3 and the rotation speed measuring instrument 4 are respectively and electrically connected between the controller 2 and the motor 6, and the controller 2 automatically realizes intelligent control on the platform door 7 through the fed back current and the speed of the rotation speed change of the motor 6. The platform door intelligent control device is arranged at the entrance and the exit of the train door and corresponds to the upper side and the lower side of the track respectively; the platform door intelligent control device is provided with a plurality of platform doors along the length of a subway platform and is electrically connected with the central monitoring control panel 9 through a bus. Wherein, divide into two kinds in the condition that platform door 7 is obstructed, one is that the limbs of thing or people and platform door 7 physical contact, and another is when subway driving interval compression to about 2 minutes, and when the wind speed of platform door 7 wind-tunnel is great, great windage pressure can lead to platform door 7 unable in time to close. By the aid of the intelligent control device for the platform door, the situation that the platform door 7 is blocked can be distinguished, and once the second situation occurs, a blocking treatment method can be effectively adopted, so that the platform door 7 can be normally opened and closed under dynamic wind pressure.
Fig. 2 is a schematic diagram of an intelligent control device for a platform door according to an embodiment of the present invention, it can be seen from fig. 2 that the hall sensor 3 and the rotation speed measuring instrument 4 provide double closed-loop negative feedback signals for implementing automatic adjustment of the motor, and the adjustment stability of the intelligent control platform door can be effectively improved through double closed-loop design, and further, a current regulator is provided between the controller 2 and the motor drive 5 for regulating and controlling the current between the controller 2 and the motor drive 5. A rotation speed regulator is also arranged between the controller 2 and the motor drive 5 and is used for regulating and controlling the rotation speed of the motor 6.
Preferably, the current feedback signal and the rotational speed feedback signal behave differently when windage and physically blocked, the rate of change of the physically blocked current and rotational speed changes being significantly higher than windage. The biggest difference between the case that the platform door 7 receives windage pressure and the case that the platform door 7 is directly physically blocked is that the former causes slow change of the motor 6 for driving the platform door 7, and the motor 6 for driving the platform door 7 is changed faster when the platform door 7 is physically contacted, namely, the motor 6 stops rotating instantly, so that according to the change, the influence of windage on the closing of the platform door 7 can be effectively and automatically controlled by detecting the parameter change rate of the change process of the motor 6. When the wind resistance influences the closing of the platform door 7, the wind resistance influences the load current to be instantaneously and slowly increased, and the wind resistance slowly decreases the rotation speed of the motor 6; the impact of the resistance on the load current is a long-term instant increase, but the speed is suddenly reduced or even stopped to trigger the blocking mechanism. Therefore, the hall sensor 3 can be used to detect the current of the motor 6, the rotation speed measuring instrument 4 detects the rotation speed of the motor 6, and the detected digital signals are transmitted to the controller 2, the controller 2 regulates and controls the current regulator and the rotation speed regulator, the motor 6 can do opposite actions through the motor drive 5, namely, when the windage pressure is met, the current of the motor 6 is increased, and the rotation speed of the motor 6 is increased, so that the influence of windage on the platform door 7 is counteracted. The hall sensor 3 detects the input current of the motor 6, the double closed-loop negative feedback signal comprises a current feedback signal and a rotating speed feedback signal, and the current feedback signal reaches the controller 2 faster than the rotating speed feedback signal.
Preferably, the motor 6 is a dc brushless synchronous motor 6, and the motor drive 5 comprises a double H-bridge drive chip. Further, the tachometer 4 comprises a magneto-electric tachometer, which is capable of transmitting data of the change of the rotational speed of the motor 6 directly to the controller 2. Therefore, when wind resistance affects closing of the platform door 7, the direct current brushless synchronous motor 6 can be driven by the double H-bridge driving chip to rapidly react, and the direct current brushless synchronous motor 6 can realize stable and frequent conversion speed.
Further, the controller 2 comprises a double PLC control chip, and the control stability is improved through the redundant control chip. After the current of the motor 6 is subjected to complex mathematical current mode transformation, a current vector space is transformed from a 3-dimensional dynamic model to a 2-dimensional static model, then sampling is carried out according to a certain time period (50 ms-250 ms), and the average value of the current threshold value of the motor 6 is calculated through a PLC control chip. The instantaneous slow increase of the current of the motor 6 under windage becomes insensitive to the judgment of the average threshold value, so the influence is smaller, but the instantaneous slow increase of the current of the motor 6 is sensitive to the long-term instantaneous increase of the current of the motor 6 when the motor encounters a resistance load, the current average threshold value is instantaneously raised, and the blocking mechanism is also indirectly triggered when the motor stops triggering once the speed encounters the resistance judgment. Similarly, in the judgment of the rotation speed, the change of the rotation speed of the motor in a certain period of time is obtained through the rotation speed measuring instrument 4, and the change rate of the change of the rotation speed of the motor 6 is detected through the PLC control chip, because the change rate of the change of the rotation speed of the motor under windage pressure and resistance exists great difference, the motor 6 can automatically regulate and control, and thus the intelligent control of the platform door 7 is realized.
Embodiment two:
as shown in fig. 3, the layout structure of the intelligent station door control device disclosed in the invention at a station is schematic, from which a control system of the whole station can be seen, wherein each station door 7 is an intelligent station door control device, so that stable and efficient automatic regulation and control can be performed on the condition of encountering windage, the system mainly comprises a signal system 8, a central monitoring control panel 9 and a station integrated control device 10, wherein the signal system is electrically connected with the central monitoring control panel 9, the station integrated control device 10 is electrically connected with the central monitoring control panel 9, the central monitoring control panel 9 can realize integral monitoring and regulation on the whole station, belongs to a first-stage regulation and control unit, and can preferentially control each internal sub-regulation and control system and device in case of emergency, for example, the central monitoring control panel 9 can be closed and opened on the whole station door without being influenced by the intelligent station door control device, so that the total regulation and control on the whole station is performed on the corresponding station door 7 part, and the corresponding branch respectively corresponds to the upper and lower stations, preferably is electrically connected with the central monitoring control panel 9 and the intelligent station control panel. The platform control panel can realize manual overall control of the platform door 7. The intelligent control devices of the N platform doors are respectively corresponding to the N subway doors, so that the platform doors 7 are synchronously and coordinately controlled to normally close under wind resistance.
Other structures of the intelligent control device for a platform door in this embodiment are referred to in the prior art, and are not described herein.
