Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to the field of testing technology, and more particularly to an automated test tool for siren. BACKGROUND

[0002] In some test scenarios, tests need to be performed from different angles. For example, when testing a siren, the siren is installed in a test room, and after a test is performed from one orientation, a test personnel adjusts the angle of the siren and then repeats the test. During the entire test process, the test personnel needs to walk back and forth to adjust the angle of the siren. Based on such test environment, the work efficiency is reduced, the orientation angle is not accurate, and time is wasted and data is deviated. Therefore, it is necessary to provide an automated test work to assist the test personnel to efficiently complete the test work. SUMMARY

[0006] a motor disposed on the box, the motor configured to drive the mounting plate to rotate; and

[0007] a controller in communication with the motor to control the motor to rotate, thereby changing the angular orientation of the mounting plate and the siren mounted thereon.

[0008] According to an embodiment of the present disclosure, the automated test tool further comprises a scale dial fixed on the box for determining the angle of the mounting plate.

[0009] According to an embodiment of the present disclosure, the scale dial has a middle rotating platform, the mounting plate is fixed on the rotating platform, and the motor is configured to drive the rotating platform to rotate.

[0010] According to an embodiment of the present disclosure, the automated test tool further comprises a motor driver coupled between the controller and the motor.

[0011] According to an embodiment of the present disclosure, the automated test tool further comprises a user interface communicatively coupled with the controller.

[0012] According to an embodiment of the present disclosure, the automated test tool further comprises a sound tester disposed independently of the box.

[0013] According to an embodiment of the present disclosure, the automatic test tool further comprises a remote controller, which is electrically connected with the controller to send instructions to the controller.

[0014] According to an embodiment of the present disclosure, the motor comprises a stepping motor.

[0015] According to an embodiment of the present disclosure, the automatic test tool further comprises a voltage converter, which is electrically connected with the motor and the driver to convert an external voltage into a voltage suitable for driving the motor and the controller.

[0016] According to an embodiment of the present disclosure, the box comprises an openable door, and the user interface is arranged on the door, and the user interface comprises a touch screen.

[0017] The automatic test tool provided by the present disclosure has higher precision, higher automation, and more comprehensive test angles compared with conventional test devices. In addition, the angle can be automatically identified, manual adjustment is avoided, errors are avoided, and the azimuth angle consistency is good. In addition, through the man-machine interface, multiple interfaces can be provided for the user, such as five interfaces of automatic, manual, parameters, programs, and IO, which are convenient for the user to adjust and select the working mode.
