5B, the temperature sensor in the circuit diagram of the biological signal processing apparatus 150 shown in FIG. 5B is provided outside the biological signal processing apparatus 150 as the body temperature sensor 130 described above, Is a Bluetooth interface unit (157). Also, the 'power source' means a power source input from the battery, and the MCU may serve as the DSP 159 or the DSP 159.

The RFI filter 151 performs RFI filtering on the electrocardiogram signal input from the electrocardiogram sensor 110 to solve high frequency noise interference.

HPF 152 performs highpass filtering on the RFI filtered electrocardiogram signal.

The AC amplifier 153 amplifies the electrocardiogram signal output from the HPF 152, and the LPF 154 performs low-pass filtering on the amplified electrocardiogram signal. The low pass filtered electrocardiogram signal is input to the DSP 159.

The acceleration sensor 155 is an acceleration sensor in a three-axis direction and senses an acceleration signal generated in accordance with the motion of the driver. The sensed acceleration signal is input to the DSP 159.

The position sensor 156 measures the current position of the bio-signal processor 150, which is used to determine the current position of the driver. The position sensor 156 may be, for example, a Global Positioning System (GPS) device. The current position information measured at the position sensor 156 may be stored in the memory 158.

The Bluetooth interface unit 157 receives information about multiple bio-signals (i.e., heart rate information and body temperature information) signal-processed by the DSP 159 and basic information (current position information, bio- 150) to the user terminal 200 through the Bluetooth communication.

The DSP 159 controls the overall operation of the bio-signal processor 150 by executing one or more programs stored in the bio-signal processor 150.

For example, the DSP 159 may receive the body temperature signal and convert it into a digital signal by an ADC (Analog Digital Converter) (not shown) and store it in the memory 158.

The DSP 159 receives the electrocardiogram signal, converts the electrocardiogram signal into a digital signal by the ADC, generates an electrocardiogram waveform, detects the heart rate from the electrocardiogram waveform, and stores the detected heart rate in the memory 158. At this time, the DSP 159 executes the heart rate detection program to generate the electrocardiogram waveform, and can detect the accurate R-peak from the electrocardiogram waveform even during operation.

The DSP 159 determines the presence or absence of the driver's movement using the acceleration signal measured by the acceleration sensor 155, corrects the error rate of the electrocardiogram signal using the determined motion presence / absence result, and then detects the R-peak can do.

More specifically, the DSP 159 analyzes the measured acceleration signal and, when the driver's walking is detected, measures the walking speed of the driver and the time when the driver's walking is detected using the electrocardiogram signal measured before the driver starts walking The error rate of the electrocardiogram signal can be corrected. That is, when a walk is detected, the heart rate of the driver suddenly increases, so that the DSP 159 can compare the electrocardiogram signal of the walking time with the electrocardiogram signal measured when there is no motion.

Thereby, the DSP 159 may not misunderstand that an abnormality has occurred in the driver's health with respect to the electrocardiogram signal (or the detected heart rate) corresponding to the time when the walking (i.e., excessive motion) is detected.

The motion of the driver includes general motions such as walking and running, and can be determined using a variety of known motion detection algorithms or using new algorithms. The motion detection algorithm will be briefly described. The number of steps is measured using the zero crossing detection algorithm for data acquired using the accelerometer of the driver (for example, vertical acceleration data obtained in the motion state) Step length and distance can be calculated.

In addition, the DSP 159 may control the Bluetooth interface 157 to periodically or continuously transmit information about the multiple bio-signals and basic information to the user terminal 200.

Referring to FIG. 7, the GUI screen shows the number of steps, heart rate, body temperature, etc. of the driver.

The DB processor 320 processes the received information on the multiple bio-signals and basic information to be stored in the DB 330 and transmitted to the monitoring communication interface unit 410. The DB processor 320 can control and manage the overall operation of the DB server 300.

The DB 330 can store information on the multiple bio-signals received from the user terminal 200 for each driver using the identification information included in the basic information.

In addition, the monitoring communication interface unit 410 can transmit information and basic information about the multiple bio-signals received from the DB communication interface unit 310 to the monitoring processor 420.

The monitoring processor 420 may analyze the heart rate and the body temperature of the driver at normal times or analyze the heart rate and the body temperature in a drinking state to set a drinking determination reference value and store the reference value in a memory (not shown). The monitoring processor 420 executes a drinking state determination algorithm using the bio-signal to compare the heart rate (electrocardiogram, pulse rate) and body temperature of the multiple bio-signals received from the DB communication interface unit 310 with the alcohol discrimination reference value It is possible to determine whether the driver is drinking or health abnormality. For example, if the monitoring processor 420 detects that the pulse number and the body temperature are higher than the alcohol discrimination reference value, it can be determined that the alcohol is in the drinking state.

In addition, the monitoring processor 420 may analyze the heart rate and body temperature of the driver at a normal time, set a drowsiness discrimination reference value, and store the drowsiness discrimination reference value in a memory (not shown). The monitoring processor 420 executes a drowsiness state discrimination algorithm using the biological signal to compare the heart rate (electrocardiogram, pulse rate) and body temperature of the multiple biological signals received from the DB communication interface unit 310 with the drowsiness discrimination reference value It is possible to determine whether the driver is driving in a drowsy state or is about to enter a drowsy state. For example, when drowsy occurs, the body temperature is increased and the heart rate is lowered, so that the monitoring processor 420 can determine that the heart rate is drowsy if the measured heart rate and the difference between the body temperature and the drowsiness discrimination reference value are greater than the threshold value.

If it is determined that the driver's health is abnormal or is in a drunk state or a drowsy driving state, the monitoring processor 420 sounds an alarm or transmits a warning message to the manager's smartphone, A warning screen can be generated together with the current position of the driver.

The user interface unit 430 may provide an interface path between the monitoring integrated management server 400 and the administrator, and may include an alarm sounding device that sounds an alarm sound, and a monitor that displays a warning screen. This allows the administrator to monitor the health status of the driver in real time.
