Problems solved by technology

[0008] The announcement date applied by the inventor is February 6, 2008, and the application number is 200720018952.1. The laser remote control receiver auxiliary device named laser remote control receiver device scatters the laser light through the photosensitive cover, so that the laser light can easily irradiate the photosensitive On the element, thereby greatly increasing the photosensitive area, but the photosensitive cover described in this patent requires the photosensitive element to be located behind the photosensitive cover, and the laser remote control receiving device described in this patent is an auxiliary device for laser remote control receivers, It is not a complete receiver and needs to be used in combination with the existing laser remote control. However, due to the shortcomings of the existing laser remote control, it can only be better applied to simple remote control, such as the switch of remote control appliances, and the control of electrical appliances. Complicated remote control is not suitable, and a photosensitive cover with a larger area is required, which affects the volume and appearance of existing electrical appliances

Embodiment 1

[0105] There are many kinds of remote control electric lights now, and the remote control electric lights include remote controllers, signal receivers, and electric lights.

[0106] The laser remote control signal transmitter is used as a remote control, and the laser remote control signal receiver is used as a signal receiver. For the structure of the astigmatism plate of the laser remote control signal receiver, refer to the following Figure 4 .

[0107] The diffuser plate 41 is a fan-shaped flat box made of translucent plastic. The upper layer of the diffuser plate 41 mainly scatters the optical signal, and the lower layer diffusely reflects the optical signal.

[0108] The phototransistor 42 is located at the top of the fan-shaped diffuser 41 and at the back of the side of the diffuser 41 that is irradiated by the laser light. Since light signals are everywhere in the diffuser plate 41 after scattering and diffuse reflection, the direction of the photosensitive surface...

Embodiment 2

[0121] refer to Figure 5 , The laser remote control signal receiver includes four filter channels 521, 522, 523, 524 and a photosensitive triode and a diffuser plate installed inside. The diffuser plate 525 uses a TV screen.

[0122] Each filter channel has the same basic structure, take the filter channel 521 as an example, refer to Image 6 To illustrate, the light transmission port of the filter channel 521 is equipped with a red glass 5212 to prevent dust from entering and to filter light, and a phototransistor with a photosensitive surface facing the red glass 5212 is installed in the filter channel 521 .

[0123] refer to Figure 5 , the filter channels 521, 522, 523, 524 are installed in the parts where the TV casing 526 is in contact with the outside of the TV screen 525, and are respectively located in the middle of the top, bottom, left, and right of the TV screen, and the photosensitive surface faces the diffuser plate 525 .

[0124] The signal processing devic...

Embodiment 3

[0147] refer to Figure 7 , the projector system has a projector 61 and a screen 62, and the laser remote control signal receiver uses the screen 62 of the projector system as a diffuser.

[0148] refer to Figure 8 , the two optical components 612, 613 of the laser remote control signal receiver are installed on the projector 61, and are respectively located at the left and right of the lens 611.

[0149] The working principle of the laser remote control signal receiver applied to the projector system is the same as that of the laser remote control signal receiver applied to the TV. The screen is divided into two parts by calculating the signal difference, and the action of the laser signal on the screen is used as the remote control signal information.

[0150] The laser remote control signal transmitter has at least two buttons, one button controls the laser to send out a non-controlled laser signal, which only serves as an indicator; one button controls the laser to send...

Abstract

The invention relates to a laser remote-controlled signal receiver and an assorted laser remote controlled signal transmitter pertaining to an optical signal receiving system, in particular to the laser remote controlled signal receiver and the laser remote controlled signal transmitter. By adopting a structure of a diffusion sheet, the laser remote controlled signal receiver has the advantages of large sensitization area, low cost and additional space-free; by adopting a signal processing device which is capable of performing a complicated signal processing, the laser remote controlled signal receiver has a function of receiving a laser actuating signal; the laser remote controlled signal transmitter has a ring-like fixed structure and is capable of cooperating with a hand of a people well and sending various control signals by utilizing a gesture of the people. By using the device suite of the invention, an electric apparatus within the line of sight can be remote controlled complicatedly by the gesture.

Description

technical field [0001] The invention relates to an optical signal control system, in particular to a laser remote control system. Background technique [0002] At present, the reception of optical signals, especially the reception of laser signals, mostly uses photocells as the receiving components of optical signals, such as automatic horizontal laser marking instruments and other equipment used for laser calibration, and some laser remote control equipment will also use photocells as optical cells. Optical signal receiving element. [0003] However, due to the higher price of photovoltaic cells, the price of these devices is also higher. Due to the high price of photocells, many devices that should use photocells as signal receiving components do not use photocells. For example, some laser remote control systems are now widely used with a photosensitive area of ​​about 0.04cm 2 A photoresistor or phototransistor, but if you want to receive the laser signal well, you sho...
