Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing and better embodiment the present invention is described in further detail:
Please refer to Fig. 1 and Fig. 2, the better embodiment of fan 1 of the present invention comprises a base 10, a shell 25, a flabellum 15, a motor 16, an electric machine control system 18, a depth camera (Depth-sensing Camera) 19, one safety control system 20, a battery 22 and a brake unit 21.This motor 16 is used for driving the rotation of flabellum 15, this electric machine control system 18 be used for control motor 16 rotation, stop and rotating speed etc., wherein, this base 10, shell 12, flabellum 15, motor 16 and electric machine control system 18 are identical with existing fan in the present embodiment, do not repeat them here.This battery 22 is used for when fan 1 disconnects with external power supply providing working power for safety control system 20 and brake unit 21.This brake unit 21 is used for stopping flabellum 15.
In the present embodiment, this depth camera 19 is a TOF(Time of Flight) vidicon camera, it is arranged on the shell 25 of this fan 1, is used for taking fan 1 image on every side, and obtains the range information between the interior each point of fan 1 scene on every side and the depth camera 19.This TOF vidicon camera is when the scene around the shooting fan 1, it will launch the signal of certain wavelength, can reflex to the TOF vidicon camera during object in signal runs into scene, time difference between signal emission and the reception has namely represented the range information between object and the TOF vidicon camera, so this TOF vidicon camera can obtain the range information between the interior every bit of scene and the TOF vidicon camera.Because this depth camera 19 is installed on the shell 25 of fan 1, so the distance between every bit and the depth camera 19 namely can be considered distance with fan 1 in the depth camera 19 resulting scenes.
This safety control system 20 is used for analyzing from the depth camera 19 captured images that obtain and range information, to judge whether that object is about to enter into the operating range of flabellum 15, namely cut off the power supply of these motors 16 by electric machine control system 18 if judge the operating range have object to be about to enter into flabellum 15, and then so that flabellum 15 stop operating, to avoid the generation of accident.
Please continue with reference to figure 3, this safety control system 20 comprises a Distance Judgment module 200, a camera control module 210, an energy supply control module 220 and an electric power detecting module 230.
This Distance Judgment module 200 is used for receiving from depth camera 19 resulting range informations, and itself and some predefined values are compared.In the present embodiment, artificer or user can set first and second predefined value in advance to distinguish safety range, fence coverage and risk range, and wherein the first predefined value is less than the second predefined value.During greater than the second predefined value, i.e. the interior object of expression this scene this moment is in safety range to object in Distance Judgment module 200 is judged the scene that obtains with the distance between the fan 1; When the object in Distance Judgment module 200 is judged the scene that obtains is between the first predefined value and the second predefined value with the distance between the fan 1, i.e. the expression at this moment interior object of this scene is in fence coverage; During less than the first predefined value, i.e. the interior object of expression this scene this moment is in risk range to object in Distance Judgment module 200 is judged the scene that obtains with the distance between the fan 1.
The filming frequency that this camera control module 210 is used for according to Distance Judgment module 200 resulting scope control depth camera 19.Particularly, when the object in these Distance Judgment module 200 judgement these scenes this moment is in safety range, the event that namely can not meet accident expression at this moment, 210 of this camera control modules can depth camera 19 filming frequency be set to a lower value, take once such as per second.When the object in these Distance Judgment module 200 judgement these scenes this moment is in fence coverage, close together between i.e. expression object this moment and the fan 1, the probability that causes accidental event improves relatively, the filming frequency of 210 depth camera 19 of this camera control module is set to a higher value, takes ten times such as per second.When the object in these Distance Judgment module 200 judgement these scenes this moment is in risk range, distance between i.e. expression object this moment and the fan 1 is very near, the probability that causes contingency is very high, and this energy supply control module 220 is namely controlled the power supply that this electric machine control system 18 cuts off this motor 16 at once.In the present embodiment, the initial filming frequency of this depth camera 19 can be per second three times.
This electric power detecting module 230 is used for the power supply of detecting motor 16, when this electric power detecting module 230 detects the power supply disconnection of this motor 16, be brake unit 21 power supplies by battery 22 namely, stop operating with timely so that flabellum 15, and then avoid flabellum 15 owing to the phenomenon that inertia is rotated further occurs.Certainly, in other mode of execution, this camera control module 210 and electric power detecting module 230 also can be omitted, when namely the object in Distance Judgment module 200 is judged the scene that obtains and the distance between the fan are less than the first predefined value, the power supply that this energy supply control module 220 is namely controlled these electric machine control system 18 cut-out motors 16 gets final product, and so also can avoid the generation of accident at once.
Please refer to Fig. 4, the better embodiment of fan method of controlling security of the present invention may further comprise the steps:
Step S1: this depth camera 19 is taken the image around the fan 1, and obtains the range information between the interior each point of fan 1 scene on every side and the depth camera 19.
Step S2: this Distance Judgment module 200 receives from depth camera 19 resulting range informations, and itself and first and second predefined value is compared.The distance that obtains when judgement is during greater than the second predefined value, execution in step S3.When distance that judgement obtains is between first and second predefined value, execution in step S4.The distance that obtains when judgement is during less than the first predefined value, execution in step S5.
Step S3: the filming frequency of these camera control module 210 depth camera 19 is set to a lower value, takes once such as per second.Return afterwards step S1.
Step S4: the filming frequency of these camera control module 210 depth camera 19 is set to a higher value, takes ten times such as per second.Return afterwards step S1.
Step S5: this this electric machine control system 18 of energy supply control module 220 controls cuts off the power supply of this motor 16.
Step S6: this battery 22 is brake unit 21 power supply, with by this brake unit 21 in time so that flabellum 15 stops operating, and then avoid flabellum 15 because the phenomenon generation that inertia is rotated further.
Said fans safety control system and method are cut off the power supply of fan, thereby can be avoided the generation of accident by the distance of object distance fan around the depth camera 19 detecting real-time fans when the object distance fan is nearer.
