Problems solved by technology

[0002] At present, the gasoline engine inverter industry mostly uses some separate equipment for manual testing or semi-automatic testing. The testing process requires more personnel to participate, such as manual loading, manual switching of equipment or fixtures, and more personnel participation leads to low efficiency. Judging whether the product is qualified is prone to misjudgment, missed judgment, etc., including equipment manufacturers that do not have a fully automatic test system to provide

Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0019] Such as figure 1 and figure 2 Shown: a gasoline engine inverter automatic testing method, the following steps are used:

[0020] Step 1: Initialize the test system and turn on the power;

[0021] 1.1 Initialize the driver;

[0022] 1.2 Turn on the low-voltage power supply;

[0023] 1.3 Turn on the three-phase main power supply.

[0024] Step 2: Read the output voltage and THD value of the inverter to be tested through the test instrument. If it is correct, go to step 3, and if it is wrong, go to step 7;

[0025] Step 3: Increase the speed of the magneto to 4800RPM, and connect the load to the inverter to be tested;

[0026] Step 4: ...

Abstract

The invention provides an automatic testing method and an automatic testing system for a gasoline engine inverter, wherein the automatic testing method comprises the steps of respectively acquiring the voltage, the current and the THD value of an inverter in states such as idle state and loaded state by means of the automatic testing system, automatically generating a testing report, printing a testing label, and realizing automatic testing function of the inverter. The testing system comprises a to-be-tested inverter and a main controller. The automatic testing method and the automatic testing system are characterized in that the information input end of the main controller is connected with the information output end of a tester; the first input end of the tester is connected with the output end of the to-be-tested inverter; the control output end of the main controller is connected with the input end of a driver; the first output end of the driver is connected with the frequency modulation control end of a power supply; the power supply is connected with the power input end of the to-be-tested inverter; and the communication end of the main controller is connected with the debugging end of the to-be-tested inverter. The automatic testing method and the automatic testing system have advantages of simple structure and high operation reliability.

Description

technical field [0001] The invention relates to the technical field of generator inverters, in particular to a gasoline engine inverter automatic testing method and system. Background technique [0002] At present, the gasoline engine inverter industry mostly uses some separate equipment for manual testing or semi-automatic testing. The testing process requires more personnel to participate, such as manual loading, manual switching of equipment or fixtures, and more personnel participation leads to low efficiency. Judging whether the product is qualified or not is prone to misjudgment, missed judgment, etc., including equipment manufacturers that do not have a fully automatic testing system. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a gasoline engine inverter automatic testing method and system that is simple in structure, convenient in testing, and capable of automatic testing and judgment. The specific ...
