The invention is applicable in the technical field of remote control and provides a remote control transmitting and decoding system and implementation method thereof. The remote control transmitting system comprises a control device and an adapter plate, wherein the control device is used to generate a remote control code waveform corresponding to the remote control code edited or selected by a user and to send the remote control code waveform to the adapter plate, and the adapter plate is used to convert the remote control code waveform to a remote control signal and then send out the signal. The remote control transmitting and decoding system can transmit the standard remote control code or the remote control code edited by the user according to needs so as to conveniently finish the transmission of user defined remote control code as well as to identify and decode the remote control code. The remote control transmitting and decoding system can also be used in automatic testing equipment to replace manpower to transmit remote control signals and be used as a simple remote controller testing device. The remote control transmitting and decoding system has the advantages of low cost, high accuracy and easy operation.
Description
technical field [0001] The invention belongs to the technical field of remote control, in particular to a remote control transmitting and decoding system. Background technique [0002] The remote control is an indispensable accessory for many electrical equipment. The remote control is often used in the research and development and testing of electronic products. In the process of research and development of electronic products, a lot of remote controls are often accumulated. Differentiate the type of code sent by each remote control, and do not know the key value of the remote control button. In this case, you can only try the remote control one by one, use an oscilloscope to measure the waveform, and analyze the key value of each key. , is more troublesome and takes a certain amount of time. [0003] In addition, sometimes it is necessary to use various remote control codes to test the system, but the types of remote controls are limited, and the specified remote control ...
