Because the accelerometer can gather the acceleration of vertical direction and horizontal direction when data acquisition, so need judge acceleration and human body deflection direction simultaneously when falling down the judgement, cause to fall down to judge and take long time, be unfavorable for the deployable formula to prevent that equipment expandes and protect the human body.

SUMMERY OF THE UTILITY MODEL

Need not to monitor the health condition of deflecting and can accomplish the prejudgement to falling down in order to realize, the judgement time when practicing thrift to fall down and judging, the utility model provides a system is prevented falling by intelligence based on radar technology.

The utility model provides a technical scheme that above-mentioned problem adopted is:

the utility model provides an intelligence prevents falling system based on radar technique, includes that the deployable prevents falling equipment, still includes controller and at least one radar detection instrument, the acceleration on human vertical direction is gathered to the radar detection instrument, the controller prevents falling equipment and radar detection instrument signal connection with the deployable respectively, the controller is according to radar detection instrument signal control the deployable expansion of preventing falling equipment when the human body of prejudgement is for falling.

Further, the radar detection instrument includes radar speed meter and radar vital sign monitor.

Furthermore, the music player is further included, and the controller controls the music player to be started.

Furthermore, the intelligent temperature controller also comprises an infrared temperature measuring sensor which is in signal connection with the controller.

Further, the device also comprises a humidity sensor which is in signal connection with the controller.

Further, the anti-fall device comprises an anti-fall helmet and an anti-fall vest.

Furthermore, the anti-falling helmet is a three-section folding helmet and comprises a front section, a middle section and a rear section, a sliding rail is arranged on the inner wall of the middle section, the front section and the rear section are respectively in sliding connection with the sliding rail through sliding blocks, and the sliding blocks slide under the control of the controller.

Further, a display screen for displaying the reading is included.

The utility model discloses compare the beneficial effect who has in prior art is: the radar detector is adopted to collect the acceleration, so that the acceleration in the vertical direction can be collected, and the pre-judgment on the fall can be completed without judging the body deflection condition; when the tumble is judged, only the acceleration in the vertical direction is judged, so that the judgment time is saved, and the protection on the human body is facilitated; the whole house can be covered by adopting the radar technology, and the coverage range is wide; the radar vital sign monitor can monitor body movement, respiration and heartbeat signals and master the health condition of a human body in real time; the music playing device can play music when the infant falls down, and the fear of the infant is relieved through the music.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1, an intelligent anti-falling system based on radar technology comprises an expandable anti-falling device, a controller and at least one radar detector, wherein the radar detector collects acceleration in the vertical direction of a human body, the controller is respectively in signal connection with the expandable anti-falling device and the radar detector, and the controller controls the expansion of the expandable anti-falling device according to the radar detector signals when the human body is judged to fall down.

The radar detection instrument is installed on a ceiling, so that an activity area of an infant is a radar detection area, the acceleration of the infant in the vertical direction is monitored, a monitoring result is compared with a preset result through the controller, and if the judgment result is that the infant falls down, the anti-falling equipment is controlled to be unfolded, so that the infant is protected when the infant falls down.

Specifically, the anti-falling device comprises an anti-falling helmet and an anti-falling vest. In this embodiment, the crash-proof helmet and the crash-proof vest both adopt a body and an airbag form, and the controller can control the airbag to be deployed according to the judgment result. The anti-falling helmet and the anti-falling vest described in this embodiment are prior art, and the detailed structure is not described again.

Example 2

On the basis of embodiment 1, as shown in fig. 2, the radar detection instrument includes a radar velocimeter and a radar vital sign monitor. The radar velocimeter can realize the monitoring to the acceleration, and the monitoring to body movement, breathing and heartbeat signal then can be realized to radar vital sign monitor, can in time master the health condition through the monitoring to vital sign, if discover unusual can in time seek medical advice.

Furthermore, the music player is further included, and the controller controls the music player to be started. In this embodiment, music play device installs on preventing falling the back of the body heart, plays the music when the infant falls and can alleviate the sense of fear when the infant falls, reduces the probability that causes of infant's psychological shadow, in order to reach better effect, can adopt the comfort audio frequency that the parent-person made oneself.
