Intellegent transmitter receiver system and its operation method
First Claim
1. An intelligent transmitter receiver system comprising:
- a CPU (central processing unit) adapted to control instructions for the actions of code-transmitting mode and copy-learning mode;
a data-entry keys input circuit adapted to input signal into said CPU;
a DC battery circuit adapted to provide the necessary working power supply;
a DC voltage rectifier circuit adapted to electrically connect a DC battery circuit and convert the output power of the DC battery circuit into the necessary working voltage;
a memory adapted to store code data obtained by said CPU and the center frequency value of said digital-to-analog converter;
an indicator lamp circuit adapted to indicate current operation mode subject to the instruction of said CPU by maintaining indicator lamp means thereof constantly on when at the code-transmitting mode, or flashing said indicator lamp means when at the copy-learning mode;
a digital-to-analog converter adapted to convert digital (parallel) signal into analog signal subject to the instruction of said CPU, so as to further drive a voltage-control type high-frequency transmitting circuit to change output oscillation frequency;
a voltage-controlled type high frequency transmitting circuit adapted to transmit an oscillation frequency subject to the control of said CPU and said digital-to-analog converter;
a bandwidth extension switching circuit adapted to extend the bandwidth of said voltage-controlled type high frequency transmitting circuit;
a mixer circuit adapted to mix the wave from said internal high-frequency transmitting circuit with the wave from an external remote controller, enabling the signal to be outputted only when wave mixing achieved;
a signal amplifier adapted to amplify signal from said mixer circuit and signal from a full-channel receiving circuit into a digital serial signal receivable to said CPU; and
a full-channel signal receiving circuit adapted to receive external series signal and to output received series signal to said CPU for rapid center frequency correction.

Abstract
An intelligent transmitter receiver system is constructed to include a CPU, a data-entry keys input circuit, data-entry keys function switch, a DC battery circuit, a DC voltage rectifier circuit, a memory, an indicator lamp circuit, a digital-to-analog converter, a voltage-controlled type high frequency transmitting circuit, a bandwidth extension switching circuit, a mixer circuit, a signal amplifier, a full-channel signal receiving circuit, and a power supply circuit. The bandwidth extension switching circuit extends the working range of the transmitter receiver system. Frequency auto-correction is operated after reading of external code signal so that the efficiency of the system is improved.
