Means for Solving the Problems The present invention uses a sensor that detects electrocardiograms or heartbeats from a living body's chest, etc., and calculates calories burned per hour based on a relational formula written in advance between calories burned per hour and heart rate of the individual subject. This is a simple calorie consumption meter whose main components include a calorie consumption calculation circuit that calculates the calorie consumption and a circuit that integrates and displays the calorie consumption per time.

In a simple calorie consumption meter that uses heart rate measurement, data on the relational expression between an individual's calorie consumption and heart rate is measured in advance, and the heart rate is calculated into calorie consumption using the relational expression between calorie consumption and heart rate. Because of the processing, it is possible to measure one day's worth of measurements with high precision and without placing any physical strain on the subject under daily living conditions.

Embodiments Examples of the present invention will be described below with reference to the drawings. FIG. 2 is an implementation state diagram of a simple calorie consumption meter according to an embodiment of the present invention, which is composed of a main body 1 that calculates and displays calorie consumption, and a sensor 2 that detects heartbeat.
The main body 1 is usually inserted into a jacket pocket, and the sensor 2 is fixed to the chest.

FIG. 3 is an overall view of a simple calorie consumption meter according to an embodiment of the present invention, which includes a plurality of adjustment knobs 3 for writing data of a relational expression between the calorie consumption per hour and heart rate of an individual subject. , output pin 13 of sensor 2 that detects heart rate
a display board 6 for displaying the cumulative total of calories consumed for the current day, a display board 7 for displaying yesterday's calories consumed, and data on the dangerous calorie consumption value and the appropriate calorie consumption value per hour. It has a plurality of adjustment knobs 4 for writing, and two types of speakers 5 that emit a warning sound when the calorie consumption per hour reaches the dangerous calorie consumption value and a notification sound when it reaches the appropriate calorie consumption value. The main body 1 has a built-in terminal 9 that outputs data on calories burned per hour (the circuit configuration will be explained with reference to FIG. 3), a positive sensor 2a, a negative sensor 2b, and a ground 2c at both ends. Velcro tape 11
is fixed to a flexible band 1o sewn with
The output of the positive sensor 2a, the negative sensor 2b, and the ground 2c are output from the output pin 13 via the cord 12.

Figure 1 is a block diagram of the main body's 10 circuit configuration.
A biological heartbeat signal is detected by a sensor 2, and a heart rate calculation circuit 22 calculates a heart rate. A relational expression between the test subject's hourly calorie consumption and heart rate measured in advance with a gas analyzer is written in the data writing circuit 24, and the hourly calorie consumption is determined by the written data and the calculated heart rate. is calculated by the calorie calculation circuit 23. The memory/integration circuit 25 integrates the calculated changes in the calories burned per hour in conjunction with the timer 26 according to the memory, and the display 27 displays the accumulated calories burned for the current day and yesterday. .

In addition, the data of the dangerous calorie consumption value and the appropriate calorie consumption value measured in advance are adjusted in the set circuit B28, and the data and the calorie consumption per hour are compared in the comparison circuit 29, and the calorie consumption per hour is determined as the dangerous calorie consumption value. When the calorie consumption value is reached, the warning sound generation circuit 3o that generates a warning sound is activated, and when the appropriate calorie consumption value is reached, the notification sound generation circuit 31 that generates a notification sound is activated.

The output terminal 9 is a terminal for taking out the memory data of the calorie consumption per hour and the written data of the dangerous calorie consumption value and the appropriate calorie consumption value. Also, the set circuit A34 replaces the data writing circuit, and does not measure the relationship between each person's heart rate and calories burned per hour, but instead measures the heart rate and calories burned per hour based on average weight, gender, and age. It is set up to match the test subject.

FIG. 4 shows that the calorie consumption per hour, the dangerous calorie consumption value, and the appropriate calorie consumption value stored in the memory of the simple calorie consumption meter 1 are transferred to a personal computer 41, and a display 46 is displayed on a disk 44 in which processing software is written. Display in . In the display, the vertical axis 61 represents the calorie consumption level per hour, and the horizontal axis 49 represents the time. Incidentally, the dangerous calorie consumption value 51 and the appropriate calorie consumption value 5o are also displayed at the same time. By displaying the change 47 in the calorie consumption per hour on the above-mentioned chart, the change in the calorie consumption of the subject can be appropriately known.

Also, long-term data can be stored by storing it in memory on the disk 43.

Effects of the Invention The relationship between calorie consumption per hour and heart rate is measured in advance using a gas analyzer, and based on this data, the calorie consumption per hour is calculated and integrated based on the heart rate, so it does not cause physical pain to the subject. Furthermore, measurements can be carried out for a long time without interfering with daily life, and measurements can be made with high precision.
