Abstract
The invention discloses a subway platform screen door control method based on dual technology detection. An infrared microwave dual technology detector is used for detecting an obstacle in the closing process of a subway platform screen door to control the closing or the opening of the subway platform screen door. The method combines two detecting technologies for use, overcomes the defects of single detecting technology, and can effectively prevent the person clamping accidents of subway platform screen doors.
Description
Technical field
The present invention relates to subway shield door field, particularly relate to a kind of subway shield door control method based on two mirror Detection Techniques.
Background technology
Along with the development in epoch and the progress of science and technology, subway has become the walking-replacing tool that people commonly use.Not only convenient but also quick, therefore very popular owing to taking subway trip.But when passenger flow is crowded, people fall over each other to crowd into the subway car, easily there is subway shield door folder people accident, serious even life threatening.In order to solve the problem of subway shield door folder people, prior art proposes many subway shield door control methods based on detector, but is mostly adopt single detective technology, as infrared detection technique.Scientific research shows, the human body detection sensitivity of infrared detector to cross motion is higher, but poor to the human body detection sensitivity of radial motion, and easily influenced by ambient temperature; Microwave detector reliability is strong, higher to the human body detection sensitivity of radial motion, but poor to the human body detection sensitivity of cross motion.Therefore, merely adopt a kind of Detection Techniques accident probability of occurrence can not be dropped to minimum, therefore the present invention proposes a kind of subway shield door control method based on infrared microwave two mirror Detection Techniques.
Summary of the invention
The object of this invention is to provide a kind of subway shield door control method based on two mirror Detection Techniques preventing from pressing from both sides people.
For reaching this object, the present invention by the following technical solutions:
Based on a subway shield door control method for two mirror Detection Techniques, operate according to following steps:
S1: shielded gate starts to close;
S2: adopt infrared microwave dual technology detector to carry out obstacle detection, if detection is less than obstacle, then continue to close the door, if detect obstacle, then suspends and closes the door;
S3: close the door if suspended in step S2, then whether disturbance in judgement thing length of the halt is less than 2 seconds, if obstacle length of the halt is less than 2 seconds, then continues to close the door, if obstacle length of the halt is more than or equal to 2 seconds, then opens the door;
S4: if step S3 opens the door, then repeat this flow process.
Preferably, the infrared microwave dual technology detector of employing comprises passive infrared detector, microwave detector, infrared signal processing circuit, microwave signal process circuit and micro controller system.
Preferably, in described step S3, whether disturbance in judgement thing length of the halt is less than 3 seconds.
Compared to the prior art, beneficial effect of the present invention is: two kinds of Detection Techniques be combined, compensate for the defect of single detective technology, can effectively avoid occurring subway shield door folder people accident.
Accompanying drawing explanation
Fig. 1 is diagram of circuit of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate technical scheme of the present invention by detailed description of the invention.
See Fig. 1, the subway shield door control method based on two mirror Detection Techniques of the present invention operates according to following steps:
S1: shielded gate starts to close;
S2: adopt infrared microwave dual technology detector to carry out obstacle detection, if detection is less than obstacle, then continue to close the door, if detect obstacle, then suspends and closes the door;
S3: close the door if suspended in step S2, then whether disturbance in judgement thing length of the halt is less than 2 seconds, if obstacle length of the halt is less than 2 seconds, then continues to close the door, if obstacle length of the halt is more than or equal to 2 seconds, then opens the door;
S4: if step S3 opens the door, then repeat this flow process.
Preferably, the infrared microwave dual technology detector of employing comprises passive infrared detector, microwave detector, infrared signal processing circuit, microwave signal process circuit and micro controller system.
Preferably, in described step S3, whether disturbance in judgement thing length of the halt is less than 3 seconds.
