Description
Technical field
The invention belongs to body weight detection technique field, the more particularly to pre-heating mean of Weight-detecting device and body weight detection dress
Put.
Background technology
With the continuous improvement of people's living standards, health problem is also increasingly paid attention to, promote anthropological measuring science
Development.People generally can obtain body weight information using scale, and body fat percentage, human body water are measured using Human fat balance
Divide the human body components such as percentage, human muscle's percentage, bone weight.
Body fat is the important component of human body, has important function and effect in human body, for example：Energy is provided
Amount, protection internal organ, maintenance body temperature, absorption of assistance water soluble vitamin etc..The body of health, is the balance of body fat,
Fatty excess accumulation can produce harm to body, cause various diseases, for example：Diabetes, cardiovascular and cerebrovascular disease etc..
Wherein, Human fat balance, is after being contacted using the electrode slice in scale body surface face with the both feet of user, to pass through certain safety electricity
Stream, measures human body resistance.It is electrically conductive because intramuscular contains the moisture content such as more blood；And fat is non-conductive；From what is flowed through
Electric current understands the weight of muscle.Thus it can determine whether out, in the ratio of body weight, the content of body fat.
At present, in the market has many scales all not preheat function, especially Human fat balance, is surveyed in user using Human fat balance
When measuring body fat, in order to measure accurate data, its foot can not insulate, it is necessary to which light pin steps down in the surface of Human fat balance with scale surface.
When the surface temperature of Human fat balance is too low, the usage experience of user can be impacted so that user is relatively low in ambient temperature
In the case of, the access times of Human fat balance are reduced, and then lose the monitoring to user's body health.

Judge module 16, for judging whether the current distance is less than pre-determined distance, the pre-determined distance can be set
For 0.6m, 0.4m etc..
Warm-up control module 17, for when the current distance is less than the pre-determined distance, then the body weight detection to be filled
The heater put is preheated to the heat affected zone on the Weight-detecting device；The heater refers to resistive heater；Institute
State heat affected zone and refer to the upper epidermis of the Weight-detecting device or the standing area positioned at upper epidermis.
The warm-up control module 17, is additionally operable to when the current distance is greater than, equal to the pre-determined distance, then described
Heater on Weight-detecting device is abandoned preheating the heat affected zone on the Weight-detecting device.
Specifically, Weight-detecting device is in frustum, the week side of boss of Weight-detecting device is in arc-shaped.The microwave transceiver
The week survey of frustum Weight-detecting device is arranged on, to increase Microwave emission angle, as shown in Figure 9, Figure 10.Identification module 12,
Logging modle 13, computing module 14, acquisition module 15, judge module 16, warm-up control module 17 are arranged on the body weight detection
The inside of device.Camera is also equipped with Weight-detecting device.
According to another embodiment again of the present invention, a kind of pre-heating mean of Weight-detecting device comprises the following steps：If
Standby to open working condition, the microwave for sending certain wavelength to some direction for starting discontinuity (can ensure to a certain extent
Linear transmission)；
Within the rest periods of transmitting, equipment starts to receive and analyzes the microwave signal that reflects；
Receive back wave due to being transmitted into and have certain time delay and energy loss, and reflection of the different material to same microwave
It is different with absorbability, therefore the absorption and reflection of different distance and material to microwave used in the present invention just can be got by experiment
Data.The data got will be tested as initial data, environmental information during so as to work is contrasted, so that model, point
Separate out the environmental information in space.
When occurring movable body in space, the microwave reflected can have the change of Reflection delay, so as to analyze this
The movement tendency and movable information of object；
, can be by inquiring about the data in database, so as to obtain the related letter of reflection sources when occurring life entity in space
Breath.
The data of acquisition are analyzed, modeled, are then further processed；
Moved when meeting anthropolgical movable body to electronic scale, and move distance reaches some threshold value set before
When, equipment starts preheating mode.
When user goes to electronic scale, electronic scale can be just used；The frame of electronic scale is arc, can increase transmitting
Angle and receiving angle.
The microwave of certain wavelength is sent in the present invention, is analyzed by receiving back wave, and then to it.Draw reception with
Between transmitting when extend to energy ratio.And then analysis modeling is carried out to surrounding environment, identify life entity in certain space and
Movement tendency, when analyze someone have want use electronic scale when, electronic scale just opens preheating mode.The present invention is by reception
Return to microwave and carry out data analysis, modeling, realize the pre-warmed intelligence system of electronic scale.Without user's operation, intelligence is realized pre-
Heat.
It should be noted that above-described embodiment can independent assortment as needed.Described above is only the preferred of the present invention
Embodiment, it is noted that for those skilled in the art, is not departing from the premise of the principle of the invention
Under, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
