Below, respectively each functional module increased is described.
A, for infrared distance sensor 22
Shell 10 is provided with infrared detection 13 and LED background light (not shown), and infrared detection 13 is connected with infrared distance sensor 22, and LED background light is connected with LED background and lighting module 23.Infrared distance sensor 22 measures the distance of users and old man's machine by infrared detection 13.Such as, utilize and detect infrared distance measurement technology, infrared detection 13 outwardly sends infrared ray, and receives the infrared ray that human body reflects, and infrared distance sensor 22 can calculate the distance of user and old man's machine accordingly.In order to this distance of Measurement accuracy, multiple (such as three) infrared distance sensor can be set.
Microcontroller 21 is connected with infrared distance sensor 22, can receive it and measure the distance obtained, and judge whether this distance is less than or equal to predeterminable range.When this distance is less than or equal to predeterminable range, microcontroller 21 controls control LED background light by LED background and lighting module 23 and sends passage of scintillation light.So, even if old people because the age increases, action and consciousness be deteriorated, occur forgetful and can not find old man's machine when, when near this old man's machine time, LED background light can send passage of scintillation light, and therefore, old people also can easily find old man's machine.
In addition, when the distance of user and old man's machine is less than or equal to predeterminable range, microcontroller 21 also can control motor oscillating module 35 and export vibration signal, thus makes motor (not shown) produce vibration.Or microcontroller 21 also can control dio Output Modules 36 and send the clear and melodious sound with the position of reminding user monitoring old man machine.
B, for three axis accelerometer 24
Three axis accelerometer 24 is for obtaining user's acceleration in three-dimensional (i.e. X, Y, Z tri-directions of coordinate system) in moving process.BMA250E chip can be adopted as the acquisition chip of three axis accelerometer 24, and this acquisition chip is connected with microcontroller 21 by I2C (Inter-IntegratedCircuit) bus, can communicate.
Microcontroller 21 receives the acceleration three-dimensional from three axis accelerometer 24, and carries out walking counting and heat exhaustion calculating according to the acceleration received.Particularly, user is in motion (such as morning runs) process, and the acceleration of its health on X, Y, Z tri-directions can do cyclically-varying along with paces.Calculate total resultant acceleration according to the component of acceleration on three directions, by the time between the paces of user and each paces can be judged after Filtering Processing, thus can walking counting be carried out; Again according to the information such as age, height, body weight, movement time of user, the heat consumed in user movement process can be calculated.
On the one hand, microcontroller 21 can be carried out data that walking counts to get and carry out the data that heat exhaustion calculates and be presented on the display screen 11 of old man's machine.On the other hand, wireless communication module 27 by these data upload health data service centres, can be inquired about for long-range user terminal.Wherein, health data service centre is the cloud server for managing each old man's machine uploading data as a whole, and the terminal such as computer, mobile phone obtains corresponding data by accessing this center.Therefore, long-range terminal use can recognize walking-meter logarithmic data and the caloric consumption data of the user of monitoring old man machine in real time.
In addition, when human body is in static or motor process, when there is instantaneous falling down, its resultant acceleration data will change.Microcontroller 21 can calculate resultant acceleration according to the component of acceleration on three-dimensional, and combines the state that algorithm of falling differentiates user movement.For old people user, once detect that old people is in the state of falling, microcontroller 21 can control wireless communication module 27 and send to designated terminal information of falling and fall point out old people there occurs, and such as, calls or send note help information to appointment relatives cell-phone number.Therefore, when old people falls, long-range children or guardian can be known in time.
Except automatically sending the mode of information of falling, in another implementation of the present embodiment, old man's machine also can comprise SOS button 14.When user presses SOS button 14, wireless communication module 27 can be triggered and send distress signals to designated terminal.
C, for Hall element 25 and GPS module 26
Hall element 25 can detect the orientation of user current location in motor process.GPS (GlobalPositioningSystem, global positioning system) module 26 can be used for positioning the current location of user equally.Hall element 25 coordinates GPS module 26, and adopts the many algorithms such as AGPS (AssistedGlobalPositioningSystem, auxiliary global satellite positioning system) to locate more exactly.
Microcontroller 21 can obtain the current location of user from Hall element 25 and GPS module 26, judge that whether the current location of user is beyond predeterminable area accordingly.Wherein, predeterminable area is the region for limiting User Activity scope pre-set in old man's machine.Such as, can centered by the residence of user, predetermined radius is 2km border circular areas is the region limiting User Activity scope.
When described current location exceeds described predeterminable area, microcontroller 21 controls wireless communication module 27 and sends position indicating information to point out user beyond predeterminable area to designated terminal.So, long-distance user can know the moving position of the user of monitoring old man machine in time, prevents from wandering away.
GPS module 26 can adopt UbloxF-7020 chip, and it is connected with microcontroller 21 by serial ports.
