Problems solved by technology
[0003] However, this technology has the following unavoidable power consumption problems: the functions of the processing unit include receiving control signals, sleeping, waking up, judging the correctness of the control signal information, analyzing the information contained in the control signal and sending the corresponding operation signal, The function of the connection with the signal receiving unit and the external drive circuit is relatively complicated, so that the circuit is able to allow the receiving unit to receive signals at any time, so as to wake up most of the main body of the processing unit in a dormant state. It will consume a considerable amount of power, and it is indeed a big test for devices that use battery power

Embodiment Construction
[0043] Please refer to FIG. 2 , which is a schematic diagram of the circuit structure of the present invention, which mainly includes a signal receiving unit 210 , a first processing unit 220 and a second processing unit 230 . The first processing unit 220 is connected to the signal receiving unit 210 and the second processing unit 230 .
[0044] The first processing unit 220 at least includes a power-saving control circuit 221, a voltage output circuit 222 and a signal transmission and reception circuit 223. The power-saving control circuit 221 is connected to the voltage output circuit 222 and the signal transmission and reception circuit 223, and automatically switches between the two A working mode includes a startup mode with a short execution time (for example, 1 / 9T, where T represents a time unit) and a sleep mode with a long execution time (for example, 8 / 9T). During the startup mode, the power saving control circuit 221 provides power to start the voltage output circu...

The invention discloses a wireless remote-control circuit and method of double-disposing unit, which comprises the following parts: signal receiving unit, first disposing unit and second disposing unit, wherein the first disposing unit connects the signal receiving unit to time and switch between starting pattern and rest pattern; the second disposing unit connects the first disposing unit at pre-rest pattern; the first disposing unit provides a voltage starting signal receiving unit during starting pattern, which obtains the control signal to transmit the arousing signal; the second disposing unit receives the arousing signal into the starting pattern, which enters into rest pattern after finishing logical circuit starting. The invention can simplify the complexity of single disposing unit circuit, which avoids the circuit from wasting large amount of power.
Description
technical field [0001] The invention relates to a wireless remote control receiving circuit, in particular to a remote control receiving circuit which utilizes double processing units to achieve performance division and has power saving function. Background technique [0002] Please refer to FIG. 1, which is a known remote control circuit designed by utilizing a single processing unit. This circuit has a signal receiving circuit 101, a processing unit 102 with a sleep function and an external drive circuit 103. The signal receiving circuit 101 is used To receive a wireless signal, and after receiving the wireless signal, convert it and send a control signal, the processing unit 102 is connected to the signal receiving circuit 101 and enters a sleep state after initialization, and then proceeds when receiving the control signal The operation of waking up from the dormant state first judges whether the information of the control signal is correct after waking up, and then send...
