Problems solved by technology

In these remote operations, there are a large number of regular repetitive actions (such as repeated channel search), recording operations (for easy reproduction), and random operations (such as looking for BUG), which are quite labor-intensive.

Embodiment Construction

[0021] Such as figure 1 As shown, the remote control data code generating device is a PC (computer), the remote control signal generating device is an MCU (micro processing unit), and the infrared signal transmitting device includes a triode Q1, an infrared light-emitting diode D1, resistors R1, R2, and one end of the resistor R2 is connected to The emitter of the transistor Q1 is grounded at one end; the anode of the infrared light-emitting diode D1 is connected to the power supply, and the cathode is connected to the collector of the transistor Q1; the base of the transistor Q1 is connected to one end of the resistor R1, and the other end of the resistor R1 is connected to a 5V power supply. The MCU used in this example is a single-chip microcomputer that conforms to the MCS-51 standard. P3.0 / RXD (data input pin), P3.1 / TXD (data output pin) are connected to the PC through the RS232 serial port to obtain the 8-bit remote control data code DATA, After processing by the MCU, th...

Abstract

The invention provides a method for automatically emitting infrared remote control signals and a system thereof, wherein the method is capable of simulating infrared TV remote control signals emission. The method comprises the following steps: a, a remote control digital code generation device records the remote control operation and generates operation subscripts to memorize, and sends digital codes to a remote control signal generation device based on the operation subscripts; b, the remote control signal generation device receives the data codes sent by the remote control data code generation device, simulates to generate the remote control signals by controlling time length of outputted carrier electric signals or low electric level signals matched with carrier frequency of the infrared remote control signals, and sends the remote control signals to an infrared signal emission device; and c, the infrared signal emission device converts the received electric signals to the infraredsignals to emit. The method only programs remote control commands on the remote control data code generation device, and then sends the remote control commands to the remote control signal generationdevice so as to automatically remote control test the television.

Description

technical field [0001] The invention relates to remote control technology, in particular to the TV remote control signal transmission technology. Background technique [0002] Whether in design, production or large-scale use, most of the control operations such as testing and setting of media products such as TVs are completed by manual remote controls. The dedicated remote control chip in the remote control generates a specific infrared signal to form a TV remote control signal by shorting the buttons. The commonly used infrared signal code is NEC code. There are a large number of regular repetitive actions (such as repeated station search), recording operations (easy to reproduce) and random operations (such as looking for BUG) in these remote operations, which are quite labor-intensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an infrared remote control signal automatic transmitting method and its syst...
