SOLUTION: A power source circuit 13 generates driving power by the electric power from a battery 12 for driving. A vibration sensor 10 is mounted on an object to be measured and detects the vibration thereof to generate a sensor output. The output is amplified 11 and A/D-converted 14 to be sent to a control circuit 20. A RAM 18 always receives a source power from a battery 19 for backing up, and stores a data related to the sensor 10. A circuit 2 measures the elapsed time to detect the presence of the output of the sensor 10 and judges whether detection time is reached or not from the elapsed time to send a direction to the circuit 13 to use the battery 12 by power of the battery 19 when the detection time is reached so that an operation is performed by a driving power of the battery 12 to calculate the time up to the subsequent detection and the results are stored in the RAM 18.

The control for accumulating the operating time of the DUT is performed based on the output from the.

The RTC 23 is constantly supplied with power from the backup battery 19. The RTC 23 counts clock pulses and measures elapsed time.

In this embodiment, the switch section includes an integrated circuit 31, diodes 32A to 32C, and a transistor 33.

The integrated circuit 31 of the power supply circuit 13 includes a battery 12
Power is always supplied from Then, the integrated circuit 31
Receives the signal a from the setting circuit 16. This signal a
Is temporarily set to the “H” level by the data input of the setting circuit 16, that is, the pressing operation (switch ON).
Upon receiving the signal a, the integrated circuit 31 applies the signal a to the diode 32A via the inverter 31A.

The integrated circuit 31 also receives the signal b from the PIO 17. This signal b is the output of the port of the PIO 17, and is continuously set to the “H” level by the software instruction by the pressing operation of the setting circuit 16. Upon receiving the signal b, the integrated circuit 31 applies the signal b to the diode 32B via the inverter 31B.

Further, the integrated circuit 31 includes the R of the CPU 21.

It is for pull-up connection to the input side of.

The transistor 33 includes inverters 31A to 31A.
When any one of the outputs of 31C becomes the "L" level, a current flows through the diodes 32A to 32C and the diodes are turned on. This causes the transistor 33 to connect the battery 12 to the converter 34.

When the battery 12 is connected by the transistor 33, the converter 34 converts the voltage of the battery 12 into the DC voltage 101 having a predetermined value.

Next, the operation of this embodiment will be described.

The RAM 18 and the RTC 23 are always operated by the built-in battery. An operator attaches the vibration sensor 10 to the motor, for example, to check the running time of the motor.

After that, when the operator operates the setting circuit 16, the signal a from the setting circuit 16 becomes "H" level.
As a result, the transistor 33 is turned on and the battery 1
2 is connected to the converter 34. The converter 34 starts its operation and supplies the DC voltage 101 to each circuit. As a result, the data integrating device is in the operating state.

After that, the signal a from the setting circuit 16 becomes "L" level, but the signal b from the PIO 17 becomes "H" level, so that the transistor 33 is continuously turned on. In this state, the operator operates the setting circuit 16 to set the interval time T of the pulse signal generated by the CPU 21, as shown in FIG.

Depending on the time measured by the RTC 23, the CPU 21
Generate each pulse of the pulse signal. The time when each pulse of the pulse signal is generated is the detection time for detecting the presence or absence of the output of the vibration sensor 10.

Between the pulse P1 and the pulse P2 of the pulse signal generated by the CPU 21, the signal a output from the setting circuit 16 and the signal b output from the PIO 17 are at "L" level and output from the CPU 21. Signal c
Is the "H" level. As a result, the transistor 33
Is turned off and the current from the battery 12 is supplied only to the integrated circuit 31. As a result, the consumption of the battery 12 is reduced.

When the pulse P2 is generated, the motor is running. At this time, the vibration sensor 10 produces a sensor output. The sensor output is amplified by the amplifier circuit 11 and converted into a digital signal by the A / D conversion circuit 14.
After that, the sensor output is sent to the CPU via PIO17.
21 added. Since the CPU 21 detects "presence" of the sensor output by the pulse P2, it sets the signal c to "H" level. Then, the transistor 33 is turned on, and the converter 34 generates the DC voltage 101. This allows
The data accumulator is in operation.

At the same time, the CPU 21 stores the interval time T until the next pulse in the RAM 18. This series of operations continues until the pulse P3.

When the pulse P4 is generated, the motor is stopped. At this time, since the CPU 21 detects "absence" of the sensor output, the signal c is set to "L" level. As a result, the supply of the DC voltage 101 is stopped. At the same time, the CPU 21 stops storing the interval time T.

As a result, the motor operating time T1, T2
Are stored in the RAM 18.

When the operator checks the operating time of the motor stored in the RAM 18, the setting circuit 16 performs a push-down operation related to data output. This turns on the transistor 33, and the converter 34 supplies a DC voltage to each circuit. The instruction to read the data is applied to the CPU 21 via the setting circuit 16 and the PIO 17. The CPU 21 reads out the data in the RAM 18,
This data is displayed on the LCD 15 via the PIO 17.

Thus, according to this embodiment,
The operating time of the DUT is accumulated and displayed. At this time, between the detection time and the next detection time, RAM 18 and R
Since only the TC 23 is supplied with electric power from the backup battery 19, it is possible to reduce the consumption of the battery 12. Thereby, the operation time can be measured for a long time.

In this embodiment, the setting circuit 16 sets the interval time. However, if this time is set in the ROM 22 in advance, the operation related to the setting can be made unnecessary.

Further, although the vibration sensor 10 is used as the sensor in this embodiment, it is not particularly limited to this. For example, even when the output of a temperature sensor, humidity sensor, etc. changes constantly,
Set the threshold. Then, the time when the sensor output is above the threshold value or below the threshold value may be integrated.

[0056]

As described above, the inventions of claims 1 to 6 limit the supply of electric power by the driving battery only to the detection time. As a result, the consumption of the driving battery can be reduced, and it becomes possible to integrate the operating time of the measured object for a long time even when driven by the battery.
