The sensors M1, M2, ..., MN may be touch sensors that detect the presence of a human body in the bedding 1, or temperature sensors that detect the temperature of each part of the bedding 1, Other sensors may be used as long as they can detect the posture of the human body with respect to the bedding 1. Further, each of the sensors M1, M2, ..., MN is electrically connected to the monitor means 2 to enable mutual communication.

FIG. 2 shows the internal circuit configuration of the monitor means 2, which has a main switch for turning the power on and off, a mode switch for selecting a mode such as a time alarm mode and a notification mode for the posture of the human body. Switch unit 21, temperature sensors M1 and M2 inside the bedding 1 ...
・ The temperature sensor output signal from MN is input, and the detection signal corresponding to the temperature is time-divided based on each sensor output signal.
(Analog-to-digital) Temperature detection circuit 22 for outputting to conversion circuit 29, and CPU as arithmetic means and control means
20 and a RAM 23 as a memory for inputting / outputting data to / from the CPU 20. Reference numeral 24 denotes a frequency divider circuit, which receives the oscillation frequency signal from the oscillator circuit 25 and outputs a clock signal T obtained by dividing the frequency signal to the CPU 20. Further, reference numeral 26 is a display unit such as an LCD for visually displaying contents such as time and selection mode. Reference numeral 27 is a drive circuit connected to the CPU 20, and when a drive signal is input from the CPU 20, it drives a notification unit 28 such as a buzzer, a speaker or a vibrator. Thereby, the notification unit 28
Is notified by sound, vibration or other means. In this case, the notification unit 28 selectively notifies the time alarm, the bedding off, and the like with different sounds or the like depending on the selection mode in the switch unit 21. In addition, the temperature detection circuit 22,
The AD conversion circuit 29 operates under the control of a signal from the CPU 20, and the CPU 20 receives the digitized temperature data from the AD conversion circuit 29.

FIG. 3 shows the internal structure of the RAM 23, which is a memory means, and includes a "display register" for storing display data displayed on the display unit 26 (see FIG. 2) and a "timekeeping register" for storing the current time. , An “alarm time register” that stores the alarm time, an “L” register that stores the mode selected by the switch unit 21, an “FO” register that stores ON / OFF of the time alarm, and a human body detection for the bedding. It is provided with a "F1" register for storing ON and OFF and a "C" register for storing a timer time such as 10 minutes. Further, the temperature of the "M1 register", "M2 register", ... "MN register", etc. for storing the temperature data detected by the sensors M1, M2, ..., MN arranged in the bedding 1 respectively. It has a register and a "P" register that specifies the address temperature register.

FIG. 4 is a flow chart of processing by the CPU 20, and FIG. 5 is a flow chart of detection processing for bedding incorporated in this flow chart. In FIG. 4, step S0 indicates a waiting state, and if there is a timing signal, step S0
When there is a time counting process of 2 and a key input, the process proceeds to the key process of step S1. The key processing (step S1) is to perform mode setting and change such as time display mode and time alarm on mode. Further, in the timekeeping process of (step S2), a signal is input to the "timekeeping register" of the RAM 23 at a timing of every second to measure the time. Then, in step S3, it is detected whether "1" is stored in the "FO" register of the RAM 23. If "1" is stored, the alarm is sounded at the alarm time. In the time alarm ON mode, the current time is compared with the set alarm time in this mode (step S4), and when these coincide with each other, the CPU 20 outputs a drive signal to the drive circuit 27, which causes the notification unit 28. Is activated to sound the alarm time (step S5). On the other hand, if "0" is input to the "FO" register, the process proceeds to step S6 without shifting to the time alarm mode. Step S6 is a step of determining whether or not the detection mode is for the bedding 1, and when the "F1" register of the RAM 23 is "1", the detection processing shown in FIG.
7), and if it is "0", display processing (step S
Go to 8). In the latter display process, the display unit 26 displays data according to the selection mode.

On the other hand, in the former detection process, as shown in FIG. 5, a signal every 1 second is added to the "C" register of the RAM 23 to perform the timer operation (step S11), and the timer in the "C" register is set. It is determined whether the data has reached 10 minutes (step S12). When this data matches (when 10 minutes have elapsed in the illustrated example), C
The PU 20 drives the temperature detection circuit 22 and the AD conversion circuit 29 to convert the sensor signals from the sensors M1, M2, ... MN of the bedding 1 into digital signals, and the corresponding "M1 register", "M2 register" of the RAM 23, ... Each is stored in the "MN register". For this storage, the "P" register of the RAM 23 is first set to "O", the detected temperature of the sensor M1 is stored in the "M1 register" of the RAM 23, and then the "P" register is set to "1" to detect the sensor M2. The temperature is stored in the "M2 register", and thereafter, the address of the P register is updated to store up to the MN register to store the detected temperature of the corresponding sensor in the corresponding register. The CPU 20 determines whether or not the sleeping human body is detached from the bedding 1 based on the data in these registers (step S14). Such a determination is made, for example, by detecting at least one of the following criteria. That is, (1) it is determined that the human body is protruding from the bedding 1 when the temperature detected by the plurality of sensors arranged in a line at the outer side of the sensors arranged in the bedding 1 is 25 ° C. or higher. (2) In addition to the determination in 1 (1) above, when the number of detected temperatures from all the sensors is 25 ° C. or more and less than a predetermined number or less, it is determined that the bedding 1 is protruding. (3) A temperature distribution map of the bedding 1 in a normal sleeping state (for example, a distribution of 25 ° C. or higher) is stored and stored in advance in a ROM or the like, and the number of detected temperatures greatly decreases with respect to this temperature distribution map. If the human body is out of the bedding 1, it is determined that the human body is protruding from the bedding 1.

When the CPU 20 determines that the human body is protruding by the above determination, the drive circuit 27 causes the alarm unit 28 to perform an alarm operation (step S15). The alarm sound in the alarm unit 28 is different from the alarm sound of the time alarm, and thereby the alarm corresponding to the sleeping person or the people around is performed. Therefore, by the above operation, it is automatically monitored whether or not the human body of the sleeping person is protruding from the bedding 1, and when it is protruding, a notification is given, so that the person stays in the state of protruding from the bedding 1 for a long time. It is possible to prevent a cold and to prevent a cold.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, as the bedding 1,
In addition to futons, blankets, and blankets, electric blankets and electric blankets may be used. Further, the detection and determination of the posture of the human body at bedtime may be performed based on other criteria, and data other than temperature, for example, pressure fluctuation data or data for detecting contact with a human body may be used. Further, the protrusion of the human body may be determined based on the temperature data comparison of each sensor.

[0013]

As described above, according to the present invention, the protrusion of the human body from the bedding at bedtime is automatically monitored and notified, so that a disease such as a cold caused by the protrusion can be prevented.
