The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing this utility model is elaborated.

As shown in Figure 1, this utility model uses the 5V dry cell power supply, awareness tool comprises body temperature collection, pulse collection, cardioelectric monitor, awareness tool perception human body is putd question to and pulse signal is sent into flush bonding processor by A/D interface and input/output interface respectively, the electrocardiosignal processing module gathers electrocardiogram (ECG) data by electrode slice, send into flush bonding processor by serial ports, flush bonding processor carries out relevant treatment to human body physiological parameter and electrocardiogram (ECG) data, sends by radio transmitting and receiving chip.Wherein: sensing element comprises body temperature trans, pulse transducer, electrocardio processing module.

A) the body temperature collection is by body temperature trans perception body temperature, body temperature trans can be selected high-precision platinum resistance, its resistance changes along with the variation of body temperature value, after the device power, the platinum resistance resistance begins to change, resistance value converts magnitude of voltage to behind sample circuit, again through amplifying and filter circuit, voltage signal is sent to the appointment analog digital conversion pin of flush bonding processor, convert the body temperature analog quantity to digital quantity body temperature value, flush bonding processor is stored in this digital quantity body temperature value in the body temperature variable.

B) pulse collection is beated by pulse transducer perception human pulse, pulse transducer can adopt a kind of piezoelectric type miniature pressure cell, after the device power, pressure transducer begins to detect beat pulse, its dynamic pressure signal becomes the quantity of electric charge by thin film, process amplifying circuit and filter circuit convert high level signal to and export to the assigned I of flush bonding processor/O pin again, flush bonding processor is by the intervalometer timing, calculating this assigned I/O pin in timing (such as 1 minute) becomes the number of times of high level, obtain the number of pulse, flush bonding processor is stored in the pulse value that calculates in the pulse variable equally.

C) cardioelectric monitor leads and the electrocardio processing modules implement by comprehensive II, after the device power, flush bonding processor sends the electrocardiogram acquisition order to the electrocardio processing module, electrocardio negative electricity pole piece, the positive electrical pole piece, the ground electrode sheet begins respectively to gather right clavicle mid point lower edge, left anterior axillary line the 4th intercostal, the electrocardiogram (ECG) data that takes under the xiphoid-process and locate, give the electrocardiosignal processing module by three radical center electric conductance on lines with the data of Real-time Collection again, this electrocardiosignal processing module comprises the amplifier that is connecting successively conducting wire, wave filter, analog-digital converter, and the time constant module that electrically is connected with amplifier, the body electrical signals that collects is through the amplification in the signal processing module, filtering, after the analog digital conversion, carry out digital filtering by this processing module, waveform recognition, send the binary system electrocardiogram (ECG) data to flush bonding processor by serial ports at last, flush bonding processor is to being stored in the form of electrocardiogram (ECG) data with array element in the electrocardio array.
