Temperature sensor is used for detecting body temperature

Select chip DS18B20:

Connect simple, it is only necessary to an I/O mouth line of processor. Measure temperature range and cover body temperature (20 DEG C-45 DEG C), it is desirable to temperature measurement accuracy can at 0.0625 DEG C. Temp sensing function requirement can be met and connect circuit:

DS18B20 only has three external terminals. Two are used for connecing power supply (pin 1) and ground (pin 3), and one is holding wire (pin 2)

Pin 1: meet power supply 3.3v.

Pin 3: welding system ground.

Pin 2: connect the XEINT16/KP_COL0/GPH2_0 pin of the CPU (model is S5PV210) of Cortex-A8 type, connects circuit such as Fig. 6.

In Fig. 6:

R1, the resistance of optional 6.2K resistance.

Now the XEINT16/KP_COL0/GPH2_0 pin of S5PV210 is by arranging GPHUP depositor disabling S5PV210 pin inner portions pull-up function, use external pull-up resistor instead, meeting while XEINT16/KP_COL0/GPH2_0 pin input/output function quickly switches, load characteristic can be effectively improved, reduce the power problems that this pin brings simultaneously.

C1, the electric capacity of optional 0.047uF. Effectively shorten the rising and falling time on pulse edge on XEINT16/KP_COL0/GPH2_0 pin, improve the transfer rate of data.

DS18B20 data wire follows single bus data host-host protocol, and S5PV210 is without single bus data transmission control unit (TCU).

To in S5PV210 pin configuration process, XEINT0/GPH0_0 pin needs to be configured to trailing edge triggered interrupts pattern, can so that the request of afe4400 can be realized quickly response by S5PV210 when the program of operation, it is possible in the middle of effectively solving, after disconnected responder end of run, encountered interrupt request singal level does not also cancel problem.

Abnormal phenomena is there will be: losing a little, data are beated when collecting the low speed datas such as human body temperature, humidity, blood pressure, pulse.

Solution:

Increase the storage depth of sampled data

For losing a problem, the way trying to achieve adjacent 2 intermediate values is utilized to be solved by the way of interpolation.

For data tripping problems, suitably increase sampling rate (sample rate > 20 times/S), Digital smooth filtering algorithm is introduced in a program under the premise meeting response time and being not less than 0.5 second, current data and historical data are associated computing, obtain truthful data and process and display.

Collect three-axis sensor data

It is mainly used in perception human body whether to have the position of burst to offset phenomenons such as (as stumbled) falling down to occur, it is necessary to quickly, accurately and have certain prediction perspective.

Take following measures:

Increasing sample rate (sample rate > 500 times/S), the system task working time tilts to three-axis sensor, processes reserved grace time for data.

Prestore in data base fair curve: the associated data of sensor output during containing following characteristics of human body's state.

The action of human body: stand, walking, jog, etc.

Human body attitude: seat, sleeping, stand up

The impact of human heart rate

Obtain effect:

The above-mentioned curve that prestores can efficiently solve three-axis sensor basic point calibration problem in use, it is achieved the self calibration of basic point.

Above-mentioned prestore curve can the current normal condition of effective self adaptation human body, reserved the judgement time for emergency case, the equipment that improves reliability and accuracy in detection process.
