Description
[technical field]
The utility model relates to Smart Home technical field, specially a kind of detection device of the human body from bed.
[background technique]
In many developed countries such as Japan, good European Union of the U.S., the daily behavior detection of old man is one and very important grinds
Study carefully project, these country researchers it is more and more begin to focus on the elderly because daily behavior accidentally and caused by body hurt
Evil event, and attempt to change this situation.Traditional artificial nursing is difficult to continue prison due to being limited by nursing staff's quantity
The activity of the elderly is controlled, and then researcher has invented the facility of many monitoring the elderly's state behaviors.
It can be seen that providing the problem of a kind of device detected from bed is this field urgent need to resolve.
[utility model content]
For the utility model in view of the above-mentioned problems, providing a kind of device having from bed detection function, structure is simple, uses
It is convenient, it is able to carry out bed monitored by personnel, precision is higher.
To solve the above-mentioned problems, a kind of device detected from bed provided by the utility model, the dress detected from bed
It sets with Detection electrode, signal processor, power adapter, the Detection electrode is connected to the input terminal of signal processor, institute
The body for stating Detection electrode and people forms coupled capacitor, and the signal processor has central processing unit, signal acquisition module, leads to
Module is interrogated, the signal acquisition module is connected between the Detection electrode and the central processing unit, and the communication module connects
It is connected between the central processing unit and cloud platform, the communication module uses HET-WT3200, and the central processing unit is
STM32F103C8T6 microcontroller.
Further, the distance between two neighboring described Detection electrode is 15mm.
Further, 220V power supply is converted into 15V by the power adapter.
Further, the quantity of the Detection electrode is 20, and the arrangement mode of the Detection electrode is 4 rows 5 column, and row is in bed
Length direction extend, be listed in bed width direction extend.
Further, the distance between two neighboring described Detection electrode is equal.
Furthermore the device from bed is detected in the utility model, structure is simple, and it is easy to use, it is able to carry out bed personnel prison
It surveys, improves precision, reduce rate of false alarm.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram for the device that the utility model is detected from bed.
[specific embodiment]
Referring to Fig. 1, a kind of composed structure for detecting the device from bed in the utility model is given.Detect the device from bed
Including signal processor 1, Detection electrode 201~220, power adapter 301~302, power adapter 301~302 is by 220V
It is converted into 15V.Signal processor 1 includes central processing unit, signal acquisition module, communication module.Central processing unit is
STM32F103C8T6 microcontroller is a integrated circuit, and core size is 32, and program storage capacity is 64KB, is needed
Voltage 2V~3.6V, operating temperature are -40 DEG C~85 DEG C, and input and output number reaches 37, and speed reaches 72Mhz, turns comprising data
Parallel operation A/D conversion, converts analog signals into digital signal by digital analog converter for the information that signal acquisition module receives, and
Judge whether in bed.Central processing unit has input interface, output interface.Input interface is connect with signal acquisition module, defeated
Outgoing interface is connect with communication module, for sending from bed signal.What signal acquisition module acquisition testing pole plate 201~220 issued
Signal.Communication module uses HET-WT3200, and the output interface of communication module and central processing unit connects, and central processing unit can be with
It is communicated with more cloud platforms, and realizes that data are transmitted.
Detection electrode 201~220 is placed on bed body surface, and the size of Detection electrode is 80mm*80mm, when human body is detecting
When on pole plate, since human body is conductor, body and Detection electrode form a coupled capacitor, because being connected to high frequency letter on pole plate
Number, body will absorb the electric current that a part of charge forms very little, amplify and handle which detection pole obtained by signal
It is that someone overlies above plate.Simultaneously Detection electrode for it is idioelectric close to be it is invalid, human body lies in effective coverage
It is interior to trigger multiple Detection electrodes simultaneously.The quantity of Detection electrode is 20-50, and the distance between Detection electrode is no less than
15cm, preferably 10cm-20cm, the signal avoided between Detection electrode interfere with each other, if between two Detection electrodes away from
From being just 15cm, the quantity of Detection electrode is 20, and the minimum range for triggering two Detection electrodes is more than or equal to 15cm, maximum
Distance is less than 61cm.201~220 points of Detection electrode arrange uniform arrangement for 4 rows 5, and row extends in the length direction of bed, are listed in bed
Width direction extends, while triggering at least one of every a line and just calculating in bed, has effectively prevented mobile phone and other small-sized electric conductors
Interference, triggering at least six Detection electrode issue people in bed signal.
The device from bed is detected in the utility model, structure is simple, and it is easy to use, it is able to carry out bed monitored by personnel, is mentioned
High precision, reduces rate of false alarm.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
