Abstract

PURPOSE:To enable power on/off test to be performed automatically by transmitting a command for turning off and on after a specified time lapse from power on and power off of a tested device. CONSTITUTION:Power off of a tested device 3 is monitored by a power on circuit 1 and power is turned on after a specified time lapse by an internal timer after power-off is detected. Also, power-on of the device 3 is monitored by a power-off circuit 2 and power is turned off after a specified time lapse by the internal timer after power-on is detected. Thus, after the circuits 1 and 2 are connected to the device 3, a switch for start/stop is turned on, power-off and power-on are repeated at each specified time corresponding to operation. The cycle for on and off of the timer at this time is set to 1,000 times for every 48 hours. If no abnormality is found as a result, it indicates that the test is passed, thus enabling power on/off test to be performed automatically.

The test apparatus is characterized by comprising a power-on control means for transmitting a power-on command after a predetermined time from when the power to the device under test is turned off.

Another power on/off device according to the present invention is a power on/off test device that performs a power test on a device under test that controls power on and off of its own device according to an external command, and which controls an external line. The present invention is characterized by comprising a power-off control means for sending out a power-off command after a predetermined period of time after the device under test is powered on.

Example Next, the present invention will be explained with reference to the drawings.

FIG. 4 is a block diagram showing the configuration of an embodiment of the power on/off testing device according to the present invention.

In the figure, a power-on circuit 1 has an internal timer (not shown), and is a circuit that sends a power-on command 10 after a predetermined period of time from the time when the power-off state of the device under test is detected. Further, the power cutoff circuit 2 has an internal timer (not shown), and is a circuit that sends out a power cutoff command 20 after a predetermined period of time from the time when the power-on state of the device under test is detected. By connecting these circuits 1 and 2 to the device under test as described later, power on/off tests can be automated.

Hereinafter, with reference to FIGS. 1 to 3, the power-on and
Explain how to use the cutting test device.

FIG. 1 is a block diagram showing the case where the power-on/off test apparatus of this embodiment performs power-on control and power-off control of the device under test 3, and parts equivalent to those in FIG. 4 are indicated by the same reference numerals. There is. In the case shown in the figure,
The power-on circuit 1 monitors the power-off of the device under test 3, and after detecting the power-off, the power is turned on after a predetermined period of time has elapsed based on an internal timer. At the same time, the power-off circuit 2 monitors the power-on of the device under test 3, and after the power-on is detected, the power is turned off after a predetermined period of time has elapsed based on an internal timer.

Therefore, after connecting the device of this embodiment to the device under test 3,
When a start/stop switch (not shown) is turned on, the power is repeatedly turned off and turned on at predetermined time intervals in response to this operation. In this case, the cycle of power-on and power-off by the timer is, for example, 1000 times in 48 hours.
If there are no abnormalities such as smoke, the test will be passed. In addition, you can change the timer time as necessary.

Note that if the device under test 3 is provided with a function to store and hold the operation history of the device itself, it is also possible to judge pass/fail based on the history after the test is completed.

Further, FIG. 3 is a block diagram showing a case where the power-on/off test apparatus of this embodiment performs power-on control of the device under test 3, and the power-off control is performed by the device under test itself. Equivalent parts are designated by the same reference numerals. In the case shown in the figure, the power-on circuit 1 monitors the power-off of the device under test 3, and after detecting the power-off, the power is turned on after a predetermined time has elapsed based on an internal timer. At the same time, the device under test 3 itself turns off the power.

In this case, an automatic power on/off device (not shown) in the device under test 3 powers off the device itself.

Note that the power cutoff circuit 2 is not used in this example.

Therefore, if the above-mentioned operation history function is provided in the device under test 3, it is possible to perform a start-up confirmation test in which the test device of this embodiment repeats power-on and power-off by the device under test itself. That is, if the device under test starts up correctly, the power is automatically turned off, and this is detected by the test device of this embodiment, and the power is turned on again. If the device under test does not start up due to an abnormality, the power on/off operation will stop, making it possible to detect the abnormality.

On the other hand, if the device under test continues to start up correctly, confirmation can be made based on its operation history after the test is completed.

Furthermore, Fig. 2 shows that the device under test 3 is controlled by external line control.
FIG. 4 is a block diagram showing a case in which the device under test turns on the power and controls the power off by the device under test itself, in which parts equivalent to those in FIG. 4 are indicated by the same reference numerals. In the case shown in the figure, power is turned on by an external control device (not shown) via a wired or wireless line 30. Then, this power-on is monitored by the power-off circuit 2, and after the power-on is detected, the power is turned off after a predetermined time period based on an internal timer has elapsed.

In this case, power-on circuit 1 is not used.

According to such a test, it is possible to test whether the power is turned on by remote control and the power is turned off correctly by the power on/off test device of this embodiment.

Note that if information regarding the power-on/off status of the device under test 3 is sent to the control device connected via the external line, the power will be turned on again via the external line after the power-off operation by the power-off circuit 2. It is also possible to make an investment. In this case, if the device under test 3 is provided with the above-mentioned operation history function, it is possible to check the history of repeated operations of power-on by external line control and power-off by power-off circuit 2. In this case, a circuit having the same function as the power-on circuit 1 may be provided on the external control device side.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention provides a circuit that sends out a power-off command a predetermined time after power-on of a device under test, and a circuit that sends a power-on command a predetermined time after power-off of a device under test.
