example 1

[0020] Example 1: When the switch S1 is closed, the control circuit of the wireless remote control hearing player enters the working state. Press the No. 1 key in the schematic diagram of the device, that is, the sending end sends out the corresponding wireless frequency f1, and the green light-emitting diode in the control circuit of the sending end lights up. The photocoupler U2 in the control circuit of the receiving end can receive the wireless signal with frequency f1, and at the same time the green light-emitting diode is on, that is, the No. 4 key in the device diagram is on. Then the signal of the photocoupler U2 is sent to the single-chip microcomputer U1, and the single-chip microcomputer U1 sends a signal at pin 33 to operate the play key of the hearing playback device, and the hearing playback device plays voice.

example 2

[0021] Example 2: When the switch S1 is closed, the control circuit of the wireless remote control hearing player enters the working state. Press the No. 2 key in the schematic diagram of the device, that is, the sending end sends out the corresponding wireless frequency f2, and the red light-emitting diode in the control circuit of the sending end lights up. The photocoupler U3 in the control circuit of the receiving end can receive the wireless signal with frequency f2, and at the same time, the red light-emitting diode is on, that is, the No. 5 key in the device diagram is on. Then the signal of the photocoupler U3 is sent to the single-chip microcomputer U1, and the single-chip microcomputer U1 sends a signal at pin 7 to operate the pause key of the hearing playback device, and the hearing playback device pauses the voice.

example 3

[0022] Example 3: When the switch S1 is closed, the control circuit of the wireless remote control hearing player enters the working state. Press the No. 3 key in the schematic diagram of the device, that is, the sending end sends out the corresponding wireless frequency f3, and the yellow light-emitting diode in the control circuit of the sending end lights up. The photocoupler U4 in the control circuit of the receiving end can receive the wireless signal with frequency f3, and the yellow light-emitting diode is on at the same time, that is, the No. 6 key in the device diagram is on. Then the signal of the optocoupler U4 is sent to the single-chip microcomputer U1, and the single-chip microcomputer U1 sends a signal at pin 27 to operate the reverse key of the hearing playing device, and the hearing playing device is reversed.

Abstract

The invention provides a wireless-remote-control listening player control device which is formed by a receiving-end control circuit and a sending-end control circuit. The receiving-end control circuit transmits signals received from different photoelectric couplers to a single-chip microcomputer, and the single-chip microcomputer performs different control operations on the exterior; the receiving-end control circuit is provided with the three photoelectric couplers which are green, red and yellow light emitting diodes; when the green light emitting diode lights up, the single-chip microcomputer controls an external listening player to play; when the red light emitting diode lights up, the single-chip microcomputer controls the external listening player to stop playing; when the yellow light emitting diode lights up, the single-chip microcomputer controls the external listening player to play back; the sending-end control circuit can send out three different frequencies, and the three different signal frequencies are respectively substituted by the green light emitting diode, the red light emitting diode the yellow light emitting diode.

Description

technical field [0001] The invention relates to a wireless remote control device, which is mainly used for controlling the playback of speech and listening in schools, and belongs to the technical category of intelligent control of speech and listening playback. Background technique [0002] At present, many school teachers need to manually operate when playing listening teaching. The manual operation is usually on the podium, so teachers often cannot walk around to explain to students during listening teaching. Teachers hope to have a device that can only control the voice playback equipment when they are taking voice and listening classes. Teachers teach better. Contents of the invention [0003] The object of the present invention is to provide a wireless remote control hearing player control device. [0004] A wireless remote control hearing player control device, including a receiving end control circuit and a sending end control circuit, characterized in that: the ...
