Remote controller test system and method

Abstract

The invention discloses a remote controller test system and method thereof; the remote controller test system comprises a computer, a remote control code collection device and a remote controller, and is characterized in that the remote control code collection device comprises a simulation keyboard and a microcontroller, wherein the microcontroller of the remote control code collection device receives the control instruction from the computer, controls the simulation keyboard for implementing keying action on the remote controller, and uploads the collected waveform data of the remote controller to the computer. The test method for the remote controller realizes automatic keying of the remote controller and the collection of waveform data by a computer program, can also compare the collection result with the design requirement, and thus improves the test efficiency of the remote controller.

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 preset remote controller emerges as the times require. Preset multi-functional remote control is to pre-set different remote control codes (generally dozens to hundreds of sets) of simple remote ...

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
