Problems solved by technology

[0002] The effective control distance of ordinary infrared remote control is mostly 7m. It can only control the electronic equipment within the direct sight range. If the distance is greater than 7m or the controlled object is not within the visible line range, the ordinary infrared remote control will be powerless.

Embodiment Construction

[0013] According to the manual attached figure 1 The present invention can be realized by implementing the working principle diagram of the circuit shown and the description of the accompanying drawings and the technical requirements described below.

[0014] Parameters and selection requirements of components

[0015] IC1 is a MOSFET operational amplifier. The model is CA3140. It is an 8-pin dual-in-line DIP package. It uses a MOSFET as an input operational amplifier. Its input impedance is as high as 1.5TΩ and it has a very low input current (10PA). Very suitable for weak signal amplification;

[0016] D1 is a silicon photodiode. The infrared wavelength response range of the silicon photodiode is 400-1100 μm. It can receive or be compatible with all infrared signals. The silicon photodiode in the transponder receiving circuit is commonly used as the SFH2030 silicon photodiode. Its performance is very sensitive and It has the characteristics of wide frequency response range...

Abstract

The invention relates to an infrared remote control signal repeater. The signal repeater consists of a 12V DC (direct current) power source, an infrared signal receiving circuit, a signal comparison, amplification and positive feedback circuit, a power amplification, emission and work state indicating circuit, wherein an operation amplifier IC1 in the signal comparison, amplification and positivefeedback circuit is selected from the type of CA2140. The infrared remote control signal repeater can remotely control an infrared control device upstairs or in another room through an infrared remote controller in a room, and actually the signal repeater is an infrared remote control signal relay device. When a television set in the bedroom is connected with a satellite receiver in another room,the infrared remote control signal repeater can achieve long-distance (larger than 15 m) or nonlinear transmission of infrared remote control signal by relay amplification.

Description

technical field [0001] The invention belongs to the field of electronic technology and infrared control technology, and relates to an infrared remote control signal transponder. Background technique [0002] The effective control distance of ordinary infrared remote control is mostly 7m, and it can only control the electronic equipment within the direct sight range. If the distance is greater than 7m or the controlled object is not within the visible line range, the ordinary infrared remote control is powerless. The invention can be used for an infrared remote controller to remotely control infrared remote control equipment in another room or upstairs in one room, and in fact it is a relay amplifier for infrared remote control signals. For example: If the TV in one bedroom is connected to the signal of the satellite receiver in another room, then when you need to remotely change the TV channel of the satellite receiver, you can use the remote control of the satellite receive...
