Automatic test method for microwave oven logic functions

Abstract

An automatic test method for microwave oven logic functions is characterized in that upper computer software, a control and acquisition system and a microwave oven controller are included, and the control and acquisition system comprises a control module, a UART communication module and an acquisition module; the control module is in electric control connection with the microwave oven controller;the acquisition module is electrically connected with the upper computer software through the UART communication module, so that the microwave oven controller is controlled by the upper computer software, and the acquisition module is electrically connected with the microwave oven controller and is electrically connected with the upper computer software through the UART communication module, so that information acquisition of the microwave oven controller by the upper computer software is realized; the automatic test method comprises the following operations: generating a test case, analyzingthe test case, executing the test case, acquiring microwave oven load state information, judging data and outputting a result. Through the improvement of the structure, the automatic test method has the characteristics of simplicity, reasonableness, excellent performance, accuracy in test, small error, easiness in implementation, safety, reliability and the like, and is high in practicability.

Description

technical field [0001] The invention relates to an automatic testing method for the logic function of a microwave oven. Background technique [0002] At present, there are many schemes for the automatic test of the logic function of the controller, but the judgment mode in the automatic test process is to use real-time judgment, that is, every time a piece of data is collected, it is compared with the expected result once, and then the next one is collected. The data is then compared, and the comparison is carried out continuously until the end of the current test case cycle; this method is alternately executed for collection and judgment, and the collection accuracy is poor. When the measured load status changes frequently or the judgment accuracy is high, this method Can't meet demand. [0003] At the same time, because microwave ovens mainly have loads such as numbers, icons, relays, and buzzers, these loads may have various states such as hold, flash, periodic cycle cha...

[0002] At present, there are many schemes for the automatic test of the logic function of the controller, but the judgment mode in the automatic test process is to use real-time judgment, that is, every time a piece of data is collected, it is compared with the expected result once, and then the next one is collected. The data is then compared, and the comparison is carried out continuously until the end of the current test case cycle; this method is alternately executed for collection and judgment, and the collection accuracy is poor. When the measured load status changes frequently or the judgment accuracy is high, this method Can't meet demand

[0003] At the same time, because microwave ovens mainly have loads such as numbers, icons, relays, and buzzers, these loads may have various states such as hold, flash, periodic cycle change, and digital tube digital increment and decrement under one trigger condition, and the load changes The accuracy is at the millisecond level, and the real-time judgment in the current technical solution can no longer meet the test requirements of microwave ovens. Therefore, how to realize the automatic judgment of the load action of the microwave oven at the millisecond level is a technical difficulty currently existing
