Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] figure 1 It is a schematic flowchart of a method for duplicating signals transmitted by a wireless remote controller provided by an embodiment of the present invention, as shown in figure 1 As shown, the method for copying the signal transmitted by the wireless remote controller provided in this embodiment includes:

[0026] Step 10: The control module reads the level change of the I / O port corresponding to the key, and determines the key operation type. The specific control module is the controller in the target remote controller, which is usually a single-chip microcomputer, and of course it can also be other microprocessors.

[0027] The single-chip microcompu...

Abstract

The invention discloses a copying method and a device for wireless remote control transmitting signals. The copying method for the wireless remote control transmitting signals includes that a control module reads level fluctuation of an I / O (Input / Output) port which is corresponding to a key; if a key operation type is copying, then the control module sends a control command to enable a modulation mode of a radio frequency receiving and transmitting integrated chip to be set into an amplitude-shift keying mode, so that the radio frequency receiving and transmitting integrated chip can scan and detect whether signal power of frequency points achieves a preset threshold value or not within a frequency band range; if the signal power of one frequency point achieves the preset threshold value, then the radio frequency receiving and transmitting integrated chip detects whether a signal at the frequency point has a preset rule or not; if the signal at the frequency point has the preset rule, then the first frequency point is recorded, and accordingly the purpose of copying source wireless remote control key data is achieved, users are not needed to buy special devices, the cost is reduced, the operation process get simple, and the users can perform operation of copying the source wireless remote control key data.

Description

technical field [0001] The invention relates to the technical field of wireless remote controllers, in particular to an automatic search method and device for signals transmitted by wireless remote controllers. Background technique [0002] A wireless remote control is a device that controls a machine through a wireless system. Modern wireless remote controllers are mainly composed of integrated circuit boards and buttons used to generate different messages. In practical applications, users usually need to back up wireless remote controllers. In the specific prior art, copy-type wireless remote controllers are usually used to copy The key data of the source wireless remote control. Under the existing conditions, to copy the data of the source wireless remote control to the copy-type wireless remote control, it is necessary to know the parameters of the signal transmitted by the source wireless remote control in advance, including the carrier frequency and modulation method. ...
