Long-range human body attitude monitoring device
Technical field
The utility model relates to electronic communication equipment and sensor field, especially relates to long-range human body attitude monitoring device.
Background technology
The ratio that the elderly accounts in social population is more and more high, and the problem of an aging population will be more for appearing.Because the elderly's physical function is degenerated, physique descends, and how to ensure particularly unmarried old man's personal safety of the elderly, is the problem that presses for reply.Falling is a kind of unscheduled event that generation is often arranged in the elderly.Falling of old man can cause a lot of safety problems, and 5%~15% fall causes brain injury, soft tissue injury, fracture and dislocation etc., and wherein the most serious is Hip Fracture.When meeting accident, how to give the problem that the elderly succours timely and be suggested.Industry also proposes some solutions; For example be home emergency-call system, old man's monitoring and alarming system etc.; Its mode all is to adopt the portable emergency calling set, when meeting with accident, through pressing the button on the calling set; Call information is transferred to indoor main frame through wireless mode, passes to First aid station by main frame again.Because the elderly is when falling, part may not be moved, and can't go by alarm button at all, and for this most serious case of falling, this series products but is difficult to play a role.Therefore be necessary this is made improvement.
Summary of the invention
The purpose of the utility model is overcoming the deficiency of prior art; A kind of long-range human body attitude monitoring device is provided; This device can detect the unscheduled event that the elderly falls automatically, and can send urgent call signalisation First aid station automatically, makes the old man who falls can in time obtain relief.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme: long-range human body attitude monitoring device is characterized in that comprise: the attitude detection module is used for the attitude information of human body; Main control module judges according to the attitude information of attitude detection module feedback whether human body falls, when judging that human body sends emergency call information when falling; Communication module sends to First aid station with emergency call information through public wireless network.
Further, described attitude detection module is provided with acceleration transducer and gyroscope; Acceleration transducer is used for the slotted line acceleration information, and gyroscope is used for the measured angular speed data.
Further, also be provided with the GPS locating module, when judging that human body is fallen, main control module sends to First aid station with gps data through communication module.
Further, also be provided with the Mobile Phone Locating module, when judging that human body is fallen, main control module sends to First aid station with the Mobile Phone Locating data through communication module.
The beneficial effect of the utility model is, this device can detect the unscheduled event that the elderly falls automatically through the attitude detection module, and can send the urgent call signal automatically and with old man's position informing First aid station, make the old man who falls can in time obtain relief.

Fig. 1 is the utility model theory diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Consult Fig. 1, the embodiment of the utility model provides long-range human body attitude monitoring device, comprising: attitude detection module 1 is used for the attitude information of human body; Main control module 2 judges according to the attitude information of attitude detection module 1 feedback whether human body falls, when judging that human body sends emergency call information when falling; Communication module 3 sends to First aid station with emergency call information through public wireless network.Described attitude detection module 1 is provided with acceleration transducer 10 and gyroscope 11; Acceleration transducer 10 is used for the slotted line acceleration information, and gyroscope 11 is used for the measured angular speed data.
As preferred embodiment, also be provided with GPS locating module 4, when judging that human body is fallen, main control module 2 sends to First aid station with gps data through communication module 3.
As preferred embodiment, also be provided with Mobile Phone Locating module 5, when judging that human body is fallen, main control module 2 sends to First aid station with the Mobile Phone Locating data through communication module 3.
Main control module 2 receives acceleration information, obtains vectorial mould
Wherein, a
xa
ya
zExpression is thought respectively, the x axle, and the y axle, the size of the linear acceleration of three directions of z axle, present embodiment z axle is defined as vertical direction, and the y axle is defined as the fore-and-aft direction of human body, and the x axle is defined as the left and right directions of human body.
Main control module 2 receives the angular velocity data of
gyroscope 11.
SVM and angular velocity threshold value when setting human body safety attitude, the SVM threshold value of present embodiment is 2.0g, the angular velocity threshold value is 0.5rad/s.When SVM and angular velocity surpassed threshold value, main control module 2 was judged the human bodies incident of falling, and immediately emergency call information and position of human body information is sent to First aid station.
The utility model can detect the unscheduled event that the elderly falls automatically through the attitude detection module, and can send the urgent call signal automatically and with old man's position informing First aid station, make the old man who falls can in time obtain relief.
Above-described embodiment, related structure is only as schematic illustration, the equivalent arrangements of being done according to the utility model claim such as, the technology that all should be the utility model contains.
