PURPOSE:To prevent the generation of trouble by providing the medical examination function for measuring and analyzing the physiological functions such as heart-beat, blood pressure, and the wave form on an electrocardiogram of a driver for a car, thus detecting the deterioration of the hygienic condition of the driver and transmitting alarm for the driver. CONSTITUTION:The main circuit in a measurement analysis system is installed onto the part of a roof console 18. The heart-beat signal is detected from the variation of blood flow in an earlobe by a heart-beat sensor 20 which is an electrocardiograph installed so as to nip the earlobe. The output signal of the sensor 20 is input into a heart-beat signal extracting circuit 24, and the heart- beat signal which is extracted and wave-form-shaped is input into a heart-beat increase calculating circuit 26. The calculated increase is outputted through BCD code, and digital-indicated by an indicator 28 and memorized into a memory 30, and also input into an analysis circuit. In the analysis circuit, the data of the heart-beat increase calculating circuit 26 and a standard data are compared, and an alarm 36 is operated if necessary. |
