Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, this utility model is described in further detail.It should be appreciated that detailed description of the invention described herein is only in order to explain this utility model, do not limit protection domain of the present utility model.

From shown in Fig. 1, a kind of escalator contingency survival kit described in the utility model, including: multiple image acquiring devices 110, multiple image acquiring devices 110 are arranged at the top of escalator and arrange along the traffic direction uniform intervals of escalator, and image acquiring device 110 is for obtaining the vertical orthographic view of passenger；Control device 120, control device 120 and be electrically connected with image acquiring device 110, control device 120 and be used for controlling escalator operating and shutting down.

When escalator contingency survival kit uses, automatically the image being obtained the passenger taking escalator by each monitoring image acquisition device 110 is contrast images, and this contrast images is sent to control device 120, obtain image area according to control device 120 calculating and contrast with preset value；Normal condition, the image area obtained is less than preset value, and escalator is properly functioning；When passenger is because accidentally falling, its image area is more than preset value, controls device 120 and sends the instruction that shuts down to escalator, and escalator receives the instruction that shuts down, and shuts down, it is to avoid passenger is subject to secondary injury.This escalator contingency first-aid method can significant response contingency, reduce the loss that causes of contingency, avoid as far as possible taking passenger's injures and deaths.

Escalator contingency survival kit also includes sensing the induction installation (mark) whether having passenger to enter escalator, and induction installation and image acquiring device 110 are electrically connected.Determine whether that passenger enters this escalator by induction installation, when having sensed that passenger enters escalator, this induction information is sent to image processing apparatus, image processing apparatus obtains the vertical orthographic view of passenger according to the program command preset, it is easy to start in time image processing apparatus, reduce the response time, improve recognition efficiency and accuracy.This induction installation can be the sensing apparatus such as pressure transducer, machine recognition device, infrared induction device.

Preferably, vertical orthographic view is infrared thermal imaging, it is simple to image area calculates, and reduces computing difficulty, improves recognition efficiency.

Image acquiring device 110 includes camera lens (mark); the direction of camera lens picked-up image is perpendicular with horizontal plane, it is ensured that obtains the vertical orthographic view of passenger, reduces because of the problem of image capture angle; cause that the error of Image Acquisition is relatively big, be unfavorable for image recognition.

Spacing L1 between two adjacent images acquisition device 110 is 30-70cm, it is preferred to, L1=45cm, 50cm, 55cm, multiple image acquiring devices 110 constitute a monitoring system, plan as a whole dynamically to control the change of projected area under each passenger's perpendicular condition.When the individual passenger's Relative vertical projected area on air lens monitoring elevator on elevator expands, and when expanding as 3 times of original area or be above, illustrating that accident has occurred this passenger, control device 120 controls escalator and shuts down.

From Fig. 1, shown in 2, escalator contingency survival kit also includes multiple brake unit 130, multiple brake units 130 are arranged at the side of escalator along the traffic direction uniform intervals of escalator, and arrange near step pedal, brake unit 130 is electrically connected with controlling device 120, brake unit 130 is triggered, send braking instruction to controlling device 120, control device 120 and receive braking instruction, and control escalator and shut down, prevent unexpected passenger, cause secondary injury because escalator remains in operation；Multiple brake units 130 are arranged at the both sides of escalator along the traffic direction uniform intervals of escalator, and the spacing L2 between brake unit 130 and step iron plate 102 is 10-30cm, it is preferred to L2=20cm；Spacing L3 between adjacent two brake units 130 is 20-40cm, it is preferred to L2=30cm；Brake unit 130 includes fixture 132 and trigger member 134, and fixture 132 is embedded on handrail wallboard 104, and trigger member 134 is connected with fixture 132 elasticity, and trigger member 134 color on handrail skirting board and skirting board contrast are wanted substantially, reminds people to note；Fixture 132 is provided with recess (mark), and trigger member 134 is arranged at above recess.

When contingency occurs passenger when taking escalator, generally all can be dragged by subway pulls on the step of elevator, head and the height of hands that now wounded body falls down are suitable with the height of first aid trigger member 134, wounded body need not stand up just can take advantage of a situation to catch handle lifesaving ring, furthermore wounded body gets a fright or seriously injured and elevator also can not get up in operating, instinct and trained reflex for people, act hurriedly in a messy situation and in struggling, also have the probability touching handle first aid ring, staff is from waist to lifting about 100 centimetres over the top of the head to 130 cm, 4 trigger member 134 are had at least in 130 centimetre lengths.So anyone falls down all can trigger this trigger member 134, even if failing to grip with nearest trigger member 134, other trigger member 134 can also be caught in health slides.Other people that take a lift can also bend over to help to trigger trigger member 134 simultaneously；Even if how individual fall down simultaneously, as long as wherein a people catches a trigger member 134, elevator also can stop.This trigger member 134 can be handle, handle, bracelet, button etc..

This escalator contingency survival kit performance is as follows:

(1), during escalator operation, control device 120 and start image acquiring device 110 and survival kit sense command, and the status information overlooking monitoring system and first aid stop bracelet is detected.

(2) ' locked ' zone is carried out video surveillance by each image acquiring device 110 of monitoring system, and timing carries out image interception and is sent to control device 120.Controlling device 120 and first truncated picture carries out personnel's image recognition, obtain personnel image area a, image area a is compared analysis, if when a is more than or equal to preset value, the state of identification is abnormal, controls escalator and shuts down.

(3) multiple brake units 130 are arranged at the both sides of escalator along the traffic direction uniform intervals of escalator, and the spacing between brake unit 130 and step iron plate 102 is 10-30cm, by controlling device 120, brake unit 130 state is detected in real time, get, as controlled device 130, the emergency rescue signal that brake unit 130 sends, then control escalator and shut down.
