In the illustrated embodiment, human body sensor is capacitance sensor 11.It is to be noted, human body sensor is not limited to capacitance sensor 11, but other forms of sensor can be adopted, such as adopt temperature sensor, pressure transducer etc., during by detecting the temperature of detected object or detected object, applied pressure size determines whether institute's detected object is human body.
In the illustrated embodiment, capacitance sensor 11 is used for detecting whether detected object is human body 6 (see Fig. 3, in practical operation, being generally the finger of human body).Capacitance sensor 11 one end is connected with VCC (positive source), one end is connected with GND (ground wire), draw the other end to be connected with the central processing unit 22 in signal processing unit 2, for being whether that the signal of human body 6 is sent to signal processing unit 2 by the object of the institute's contact measurement detected by capacitance sensor 11 simultaneously.Particularly, when human body contacts with capacitance sensor 11, the capacitance that capacitance sensor can be caused to detect changes, when capacitance is in the set point corresponding with human body 6, can judge that detected object is human body 6, now capacitance sensor 11 outputs signal.About concrete structure and the operation principle of set point and capacitance sensor 11, be prior art, do not repeat them here.
Heart rate sensor 12 has been used for the detection of human heart rate's signal, its one end is connected with VCC (positive source), one end is connected with GND (ground wire), draw the other end to be connected with the central processing unit 22 in signal processing unit 2, the heart rate signal for the object by institute's contact measurement is sent to signal processing unit 2 simultaneously.Heart rate sensor 12 can adopt infrared ray electric-type sensor, piezoelectric transducer and resonant transducer, preferably, heart rate sensor 12 is infrared ray electric-type sensor, it obtains heart rate signal by the arterial vascular dilatation on infrared ray projection human finger, thus obtains heart rate signal more accurately and reliably by human finger.
In the illustrated embodiment, pressure transducer 13 be used for detecting detected object whether with sensor unit 1 reliable contacts.Further, pressure transducer 13 is for improving the reliability of detection.When detecting, pressure transducer 13 be used for detecting detected object whether with sensor unit 1 reliable contacts, its one end is connected with VCC (positive source), one end is connected with GND (ground wire), draw the other end to be connected with the central processing unit 22 in signal processing unit 2, for whether object is sent to signal processing unit 2 with the signal of sensor unit 1 reliable contacts simultaneously.By pressure transducer 13 come judgment object whether with sensor unit 1 reliable contacts, thus the credibility of heart rate signal is higher, can not cause the measurement error of heart rate signal because of unreliable contact when measuring.
Signal processing unit 2 is arranged between sensor unit 1 and module interface 3, and the signal processing for being detected by sensor unit 1 becomes to be suitable for the signal received by Vehicle Controller.It comprises central processing unit 22, input resistance 23 and transistor 24.
Particularly, central processing unit 22 for receiving sensor unit 1 signal and output signal, particularly, central processing unit 22 is connected the signal being used for collecting in receiving sensor unit 1 respectively with the capacitance sensor 11 in sensor unit 1, heart rate sensor 12 and pressure transducer 13, collected signal is judged and processes, and be connected with transistor 24 by input resistance 23, for realizing, heart rate alarm signal is exported.
The driving function that transistor 24 exports for heart rate alarm signal, its one end realizes the connection with central processing unit 22 by input resistance 23, heart rate alarm signal output interface 32 in one end and module interface 3, draws one end simultaneously and is connected ground connection with GND (ground wire).
In rhythm of the heart module routine, central processing unit 22 is connected with described capacitance sensor 11 and described pressure transducer 13 respectively.Capacitance sensor 11 can judge the carrying out whether monitoring object is human body 6, only has that to meet monitoring object be after the condition of human body, and signal just can export by capacitance sensor 11.Whether pressure transducer 13 can judge with sensor unit 1 reliable contacts monitoring object, after the condition meeting monitoring object and sensor unit 1 reliable contacts, namely, after pressure transducer 3 detects certain pressure value, signal just can export by pressure transducer 13.And after only having the capacitance sensor 11 in sensor unit 1 and pressure transducer 13 all to output signal, central processing unit 22 in signal processing unit 2 just can receive the signal that heart rate sensor 12 exports, and this signal is amplified, the functional operation process of filtering, shaping and necessity, finally forms the pulse signal that can represent reflection human heart rate.Meanwhile, central processing unit 22 is by the pulse signal of its inner representative reflection human heart rate formed of Real-Time Monitoring.In the process, if central processing unit 22 monitors the pulse signal frequency of reflection human heart rate not in certain limit (1Hz to 1.9Hz), then heart rate alarm signal is exported to module interface 3.
Integrated regulator 21 for the output voltage of vehicle power being converted to the voltage being suitable for driving sensor unit 1, by the conversion of automobile DC12V voltage transitions rhythm of the heart module required voltage VCC.Its one end is connected with VCC (positive source), one end is connected with GND (ground wire), draw the other end to be connected with positive source interface 31 simultaneously, thus realize the conversion of DC12V voltage to heart rate monitoring modular required voltage VCC of vehicle power.
