TH1390C3 - Automatic remote control broadcasting system - Google Patents

Abstract

Automatic remote control system, both wireless Or a transmitted signal cable consists of 2 parts: the receiver and the transmitter Which the transmitter is able to control the exposure to the receiver farther away Power on and broadcast automatically by encoding and decoding on the same frequency DTMF, FSK, PSK, CTCSS

Claims (1)

Disclaimer (all) which will not appear on the advertisement page: 1 The automatic remote broadcasting controller consists of a transmitter or host and receiver or distant client. Its characteristic is that the transmitter consists of a keyboard (7) as a command entry unit. Where to take commands from the user And will be sent to the central processing unit (5) to send the open command signal to the encoder (3) before sending the signal to the receiver - transmitter (1) to send the signal to the receiver. According to the machine, open the circuit in preparation for receiving the broadcast signal via radio waves or a cable. And when the receiver that the user wants to open the circuit Will send a signal back to the server The receiver-transmitter (1) sends a signal to the decoder (2) to decode the client's response. Before sending it to the central processing unit (5) to process the signal and send the signal to the display (6) to display it, it is used to know the status of the receiver used as the desired client. In the meantime The central processor (5) sends a control signal to the switch (9) to direct the switch (9) to receive the signal from the signal source (10) to be broadcasted to the receiver-transmitter (1). To continue transmitting to the receiver, the receiver contains a coding sector (17) to determine the code for each receiver. When the receiver-transmitter (11) receives the encoded signal from the transmitter The received signal will be sent to the decoded sector (12) and then sent to the central processing unit (15) to compare it with the code set by the coding sector (17) and will send a response signal. Go to encoded sector (13) to respond to the server that it has received a command and that the circuit is open and ready to broadcast. The central processor (15) sends a control signal to the switch (19) to direct the switch (19) to be ready to send the broadcast signal received via the receiver (11) to the amplifier. Signal (20) to amplify the audio signal before broadcasting through the speakers. And will show the results of the receiver on the display (16) to show the working status of the receiver 2 Remote control system automatic remote broadcasting according to item 1, which both the transmitter and receiver also consist of Sound Detection (VOX) section (4,14) where Will the sound signal being broadcasted In the event that there is no signal within the specified time VOX (4,14) sends a signal to the central processor (5,15) to direct the switch (9,19) to turn off the receiving or transmitting of the audio to be broadcasted. 2 where the audio sensing (VOX) section (14) of the receiver It sends a signal to the central processing unit (15) to instruct the receiver to shut down and be in a standby state from the host or restart state. When there is no audio signal broadcast within the specified time 4, the automatic remote control system controls 1-3, according to clause 1-3. Where the encoding or decoding will be DTMF, FSK, PSK, or CTCSS.
