Problems solved by technology

) test equipment mainly includes lightning surge generators, electrical fast transient burst generators, electrostatic discharge generators, damped oscillatory wave generators, ringing wave generators, voltage drop simulators, etc., but most of them are based on different test items A single test and single control method is adopted, that is, each device only completes its specific test function, and the test devices of different projects are not compatible with each other, and an integrated test system is not formed, which ultimately hinders the host computer control of the EMS test system Technology Research and Development

Embodiment

[0014] The invention controls and coordinates the equipment required by each test item through a single control unit. Each device is connected with the control unit through the bus, so as to replace or expand the test equipment. And through the control unit, you can set the required parameters of each test item and monitor the running status of the equipment. Connect the host computer with the control unit to complete the exchange of various test data.

[0015] A. The user selects the corresponding test equipment according to the test items, during which the control unit will automatically judge whether the working status of the equipment selected by the user is normal or not.

Abstract

The invention relates to an EMS test method and test device; the test method comprises the following steps that: (1) a control unit sends instructions to each test device to inquire whether the device is connected or not; if so, whether the operation of the connected device is normal or not is judged; if the operation is normal, the step (2) is executed; if the operation is not normal, the control unit sends instruction to the test device again; if the device is not connected, the control unit sends instruction to the test device again; (2) the control unit receives parameter setting values of the test devices input by users; (3) the control unit sends the parameter setting values to the corresponding test devices; and (4) the test devices test the to-be-tested devices and send the test data to the control unit; and the upper computer reads the test data in the control unit and generates test report. Compared with the prior art, the EMS test method and test device provided by the invention have advantages of reducing cost input of users in upgrading devices and strengthening the expansibility of the test projects.

Description

technical field [0001] The invention relates to the field of electromagnetic susceptibility testing, in particular to an EMS testing method and testing device. Background technique [0002] At present, EMS (Electromagnetic Susceptibility electromagnetic susceptibility. Refers to the ability of devices, equipment or systems to avoid performance degradation in the presence of electromagnetic disturbances.) The test equipment mainly includes lightning surge generators, electrical fast transient burst generators, Electrostatic discharge generators, damped oscillatory wave generators, ringing wave generators, voltage drop simulators, etc., but most of them adopt a single test and single control method according to different test items, that is, each device only completes its specific test function, The test equipments of different projects are not compatible with each other, and an integrated test system is not formed, which finally hinders the research and development of the hos...
