Abstract
A system is used to test whether a device works normally in a preset frequency range. The system presets a frequency range, and controls a frequency generator to send a test frequency signal to the device according to each of a predetermined number of frequencies of the frequency range, and tests whether the device and electronic parts of the device can work normally to obtain test results.
Claims10
A system for testing whether a device can work normally in a preset frequency range, the system comprising:
- a frequency generator;
- and
- a test device comprising:
- a frequency setting module to preset a frequency range, and provide an initial test frequency of the frequency range to the frequency generator to make the frequency generator output a test frequency signal to the device;
- a power control module to control a power supply to provide power to the device;
- a determining module to determine whether the determining module receives a response signal from the device in a time period, and whether the device can normally boot up at the test frequency signal in response to the determining module receiving the response signal from the device in a time period;
- a detecting module to determine whether electronic parts of the device can work normally at the test frequency after the device boots up, wherein the detecting module sends a test instruction to the device to test whether a corresponding one of the electronic parts of the device can work normally, after finishing testing the corresponding electronic part of the device, the detection module gets test results, the detection module sends a shutoff signal to the power control module to power off the device in response to the test results indicating all the electronic parts can work normally;
- and
- a frequency adjusting module to determine whether the test frequency is beyond the frequency range, add a preset constant to the current test frequency to obtain a new test frequency, and send the new test frequency to the frequency generator to do a next test in response to the test frequency being not beyond the frequency range.

A method for testing whether a device can work normally in a preset frequency range, the method comprising:
- presetting a frequency range, and providing an initial test frequency of the frequency range to a frequency generator;
- outputting a test frequency signal to the device;
- controlling a power supply to provide power to the device;
- determining whether a test device connected to the device receives a response signal from the device, wherein when the device cannot boot up at the test frequency signal in response to the test device not receiving the response signal, controlling the power supply to power off the device;
- determining whether electronic parts of the device can work normally at the test frequency after the device boots up, sending a test instruction to the device to test whether a corresponding one of the electronic parts of the device can work normally, getting test results after finishing testing all the electronic parts of the device, and sending a shutoff signal to power off the device in response to the test results indicating all the electronic parts can work normally;
- and
- determining whether the test frequency is beyond the frequency range, adding a preset constant to the current test frequency to obtain a new test frequency, sending the new test frequency to the frequency generator to do a next test in response to the test frequency being not beyond the frequency range, and returning to the step of outputting a test frequency signal to the device.
