Background technology
Along with the develop rapidly of China's Urbanization Construction, urban floating population increases severely, and causes traffic congestion to become an outstanding social concern.For this reason, the each metropolis of China is all at the future development to track traffic.During the track traffic in increasing city is built and under preparation.
In urban track traffic, platform is the cut-in point of city and track circuit, is that the stream of people assembles place.Because passenger is from from all directions, and platform is an amorphous public place.So people is eventful assorted, crowded to capacity on platform, human casualty accident occurs repeatedly, and therefore, oneself has caused the concern of various circles of society the safety problem of rail traffic platform.
Safety door, is the passage that passenger normally gets on or off the bus, and is the barrier that cuts off platform and track.In the process of closing at safety door, because some passenger's consciousness is low, even the process of safety door in closing, also the action that can get on the bus or get off, if safety door does not arrange good anti-clipping system, the phenomenon that must cause passenger to crush, when having larger object turnover safety door, even can make the device damage such as safety door.Existing safety door anti-clipping system detects single, and the degree of accuracy is lower, safety that cannot effective guarantee passenger.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the safety door anti-clipping system based on drive motors current detecting that a kind of accuracy of detection is high is provided, it catches the variation of motor current signal by Hall element, energy effective guarantee passenger's safety, extend the application life of the equipment such as safety door, in conjunction with the detecting function of infrared detection module, improved the stability of anti-clipping system.
The purpose of this utility model is achieved through the following technical solutions: the safety door anti-clipping system based on drive motors current detecting, it comprises processor, motor drive module, motor, current of electric detection module, low pass filter and amplifier, processor is connected with safety door with motor by motor drive module successively, the signals collecting end of current of electric detection module is connected with motor, and the output of current of electric detection module is connected with processor with amplifier by low pass filter successively.
Further, this anti-clipping system also comprises infrared detection module, and infrared detection module is connected with processor.
Described infrared detection module comprises multiple infrared transmitting tubes and multiple infrared receiving tube, infrared transmitting tube is arranged on the offside door of safety door, infrared receiving tube is arranged on the offside door of safety door, many group infrared transmitting tubes and infrared receiving tube subtend arrange, and infrared transmitting tube is connected with processor respectively with infrared receiving tube.Each infrared receiving tube receives the light beam of multiple infrared transmitting tube transmittings successively, and periodically every light beam is carried out to scan round, forms cross scan mode.
Concrete, described current of electric detection module is Hall element.
The beneficial effects of the utility model are:
(1) by Hall element, catch the variation of motor current signal, thereby realize detection of obstacles, by processor control motor drive module, and then the operating condition of control motor, drive safety door phase down or open, avoid crushing passenger, effective guarantee passenger safety, also extended application life of the equipment such as safety door;
(2) in conjunction with infrared detection module, carry out obstacle detection function, control the operating condition of motor, improved the high stability of anti-clipping system;
(3) be provided with multiple infrared transmitting tubes and infrared receiving tube, form staggered form scanning, avoid occurring the phenomenon of scan blind spot, improve the accuracy detecting.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model;
Fig. 2 is the positional structure schematic diagram of infrared transmitting tube and infrared receiving tube;
In figure, 1-offside door, 2-offside door, 3-infrared transmitting tube, 4-infrared receiving tube.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, safety door anti-clipping system based on drive motors current detecting, it comprises processor, motor drive module, motor, current of electric detection module, low pass filter and amplifier, processor is connected with safety door with motor by motor drive module successively, the signals collecting end of current of electric detection module is connected with motor, and the output of current of electric detection module is connected with processor with amplifier by low pass filter successively.
Further, this anti-clipping system also comprises infrared detection module, and infrared detection module is connected with processor.
Infrared detection module comprises multiple infrared transmitting tubes 3 and multiple infrared receiving tube 4, as shown in Figure 2, on the offside door that is distributed in safety door 1 of multiple infrared transmitting tube 3 arrays, on the offside door that is distributed in safety door 2 of multiple infrared receiving tube 4 arrays, multiple infrared transmitting tubes 3 and infrared receiving tube 4 subtend settings, each infrared transmitting tube 3 is connected with processor respectively with infrared receiving tube 4.As preferably, the each infrared receiving tube 4 of processor control receives the light beam that multiple infrared transmitting tubes 3 are launched successively, and periodically every light beam is carried out to scan round, forms cross scan mode, avoids occurring the phenomenon of scan blind spot, improves the precision detecting.
Concrete, described current of electric detection module is Hall element.
The course of work of the present utility model is as follows: when the process of safety door in closing the door, processor is controlled on the one hand infrared detection module and is carried out obstacle detection function, control the light beam that each infrared transmitting tube 3 is launched, each infrared receiving tube 4 receives the light beam that multiple infrared transmitting tubes 3 are launched successively, and infrared detection module sends detectable signal to processor.Meanwhile, processor is also controlled the variation of Hall element Real-time Collection motor current signal, and the signal gathering successively after the processing of low pass filter and amplifier, is sent into processor.When detecting while having obstruction between the offside door 1 of safety door and offside door 2, processor is by the operating condition of motor drive module control motor, this operating condition comprises and shutting down and antiport, and then control safety door phase down or open, avoid crushing passenger, also avoid the device damage such as safety door, the application life of extension device.
