Systems and method for testing remote controller

Abstract

The invention discloses systems and a method for testing a remote controller. One system testing a remote controller is characterized by comprising a computer, a remote control code collecting device, a remote controller and a sample remote controller. The other system for testing a remoter controller is characterized by comprising a computer, a remote control code collecting device, a remote controller and a code-sending device, a microcontroller of the remote control code collecting device receives control instructions form the computer to control a simulation keyboard to implement the keying operation of the remote controller and uploads the collected waveform data of the remote controller to the computer. The remoter controller test method is characterized in that the computer controls and realizes the automatic keying and waveform data collection of the remote controller and can automatically compare collecting results with the design requirements.

Description

technical field [0001] The invention relates to the field of remote controllers, in particular to the field of testing remote controllers. Background technique [0002] At present, home appliances are mostly controlled by remote controllers. Due to the different types and manufacturers of home appliances and remote controllers, the carrier frequency and encoding format of the remote control codes of various remote controllers are also different. The simple remote controllers currently on the market generally only control one type of home appliance. With the development of science and technology and the increase of types of home appliances, the number of remote controllers in the family is also increasing. In order to solve the troubles of users facing the many remote controllers, a multi-functional remote controller has emerged as the times require. Multi-function remote controllers include preset remote controllers and learning remote controllers. The preset type remote c...

Problems solved by technology

[0008] The biggest shortcoming of the remote control testing methods and tools listed above is that they do not solve the problems of cumbersomeness, low efficiency, poor repeatability, poor consistency, and error-prone problems caused by manual keys.

Due to the use of manual buttons, the waveform data obtained by each test collection is not easily comparable. Therefore, automatic comparison between the collected data and the design requirements cannot be realized, resulting in poor credibility of the test report. In fact, it is still difficult to draw a clear Test Results

In addition, receiving the code of the remote control purely through infrared rays is greatly affected by the angle, distance and ambient brightness, the accuracy is not high, and the correct carrier duty cycle cannot be obtained, so that the remote control code analysis tool cannot analyze the waveform. It is easy to make mistakes when obtaining data, obtaining remote control code parameters, and displaying waveform graphics
