Description
Technical Field
The utility model relates to a human body prevents falling and detects technical field, specifically is a human body falls down detection device.
Background
At present, the old people live alone or pregnant women and the like cannot give an alarm in time for seeking help and cannot seek medical treatment in time due to poor physical conditions of the old people or the pregnant women and the like but not nursing in place, so that serious consequences are caused.
Also can monitor the alarm device that falls down some on the market now, mainly divide into two kinds, one kind is dressed on the person of needing nurse, and the other kind is judged through image processing mode through camera equipment. The first is that the device needs to be worn by people for a long time, so the volume and the weight of the device need to be considered, and the device needs to be charged more than the first, so the device is inconvenient to use; the second method is realized by an image processing technology, which is capable of detecting a fallen person, but such methods are easy to involve privacy problems, so that places with high privacy such as toilets, bathrooms, bedrooms and the like cannot be installed in many places, but such places are often high-incidence places of falls; so that it is inconvenient to use.
Disclosure of Invention
The utility model aims to provide a human body fall detection device, which is used for solving the privacy problem easily caused by the fall detection personnel in the background technology, so that places with higher privacy such as toilets, bathrooms, bedrooms and the like cannot be installed in many places, but the places are often high places for falling; so that it is inconvenient to use.
In order to achieve the above object, the present invention is widely applied to the technical solution of fan control, and particularly provides the following technical solution: a human fall detection device, comprising:
a base seat is arranged on the base seat,
the main control board is arranged in the base and is provided with a player and an NB-Iot communication module;
the shell is sleeved on the base and provided with a detection through hole;
the sensor is arranged in the detection through hole and is electrically connected with the main control board.
Preferably, the sensor is a time-of-flight sensor.
Preferably, a lens is further arranged on the detection through hole corresponding to the time-of-flight sensor, and the lens is arranged above the sensor.
Preferably, the casing is provided with sound emitting holes or heat radiating holes corresponding to the player.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model can form 3D images through the flight time sensor, thereby analyzing the height and the body characteristics of the human body better than the camera, and increasing the accuracy of the judgment of the falling of the human body; in addition, the flight time sensor has low pixel points, so that a clear human body image cannot be formed, and the privacy problem does not exist, so that the device can be installed in high-hair places which are easy to fall down, such as a toilet, a bathroom and the like;
(2) the utility model discloses communication module has used NB-Iot communication module to can the low-power consumption operation, and solved many scenes and do not have WIFI or the weak problem of signal; in addition, the player can give an alarm in time, so that emergency communication can be rapidly carried out on people, and the rescue probability is improved;
therefore the utility model discloses have the beneficial effect that detects accuracy, privacy nature, practicality.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides an embodiment:
a human body fall detection device comprises;
the base plate (1) is provided with a base,
the main control board 7 is arranged in the base 1, and the main control board 7 is provided with a player 6 and an NB-Iot communication module 2;
the shell 3 is sleeved on the base 1, and the shell 3 is provided with a detection through hole 31;
the sensor 5 is arranged in the detection through hole 31, and the sensor 5 is electrically connected with the main control board 7;
the main control board 7 is further provided with an MCU module, and the MCU module is used for analyzing the sensing signals transmitted by the sensor 5 and sending control signals to the player 6 and the NB-Iot communication module 2.
The sensor 5 is a time-of-flight sensor 5, wherein the time-of-flight sensor 5 is used for detecting a human body and forming a depth map signal to the main control board 7 for analysis so as to judge whether the state of the human body is normal or fallen.
The detection through hole 31 is also provided with a lens 4 corresponding to the time-of-flight sensor 5, the lens 4 is arranged above the sensor, wherein the lens 4 can pass infrared light and plays a role of protecting the sensor 5.
The shell 3 is provided with a sound hole 32 or a heat dissipation hole corresponding to the player 6; the sound emitting holes 32 or the heat radiating holes are used for the player 6 to transmit sound or radiate heat of electrical appliances such as the main control board 7 and the like.
Example (b):
the working principle of the utility model is as follows:
(1) the object distance is obtained by detecting the flight (round trip) times of these transmitted and received light pulses, while the time-of-flight sensor 5 continuously transmits light pulses to the object and then receives the light returning from the object with the sensor 5; it can be used to detect the object distance of multiple points, and form a depth map according to the detected distance, and give it to the main control board 7;
(2) when the main control board 7 judges whether the state of the person is normal or falls through the characteristic analysis of the depth map;
(3) when the main control board 7 analyzes the abnormal phenomenon, the trigger signal is sent to the NB-Iot communication module 2, and the NB-Iot communication module 2 transmits the signal to the background to inform the preset information receiving people;
meanwhile, the main control board 7 controls the player 6 to give an alarm sound so as to be heard by surrounding personnel.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
