Description

An optical signal receiving device and sand table model

technical field

The invention relates to the technical field of model control, in particular to an optical signal receiving device and a sand table model.

Background technique

At present, there are three main ways to realize model control:

1. Wired control mode, realize the switch with economical and practical physical buttons, such as household lighting switches, most of which are wired control methods. There will be differences in shape and function, but they all have the advantages of being cheap and easy to use. At the same time, they also have the disadvantage that the output signal type is single and cannot control the controlled object in a certain area.

2. Wireless remote control, this method is economical and practical in wireless control, and is widely used in the automotive industry; it is mainly used for the switch lock of the car, which can be operated flexibly and conveniently at any nearby location, but there are also single output signal types. And control points are limited defects.

3. Wireless WIFI/GPRS remote control, using mobile phone/tablet/computer as the control source, not only the output signal types are various, but also the control quantity is high and technical content is high, so there is high production cost, high requirements for professional technical level, and complicated control An operating manual is also required.

There is also a relatively novel model control method: laser pointer control. The use of lasers is ubiquitous in the manufacturing industry. In addition, safe and low-light laser pointers have become children's toys and scientific and educational tools such as engineering and education. At present, there are similar light-sensing modules on the market, which are mainly used to control street lamps or industrial intelligent indoor lighting, and realize automatic lighting at night and no lighting during the day. When it is applied to the light control system, the following problems will occur.

First, the light-sensing receiving point is too small, and the operator needs to aim accurately, otherwise it is difficult to quickly and accurately use the laser as the signal input for triggering.

Second, it will receive all visible light, so sunlight, lighting, camera flash, etc. will affect it and cause false output.

Third, the signal strength it outputs is too weak and single, and cannot be directly used for external output. It needs to be amplified during application. Even after amplification, it is just a switch signal and cannot interact with other signals. There are a total of 26 areas from A to Z, and each area has a group of lights, which are all bright at first. When introducing the A area, the laser pointer hits the receiver in the A area and outputs a signal. The A group of lights are all bright, and the other groups of lights are on. Turning into a semi-bright state for a few minutes and then returning to the original state to make its group A stand out. This is one of the linkage interactions, such as lighting and video or dynamic mechanism lifting and rotating synchronous interaction.

This technology is based on the principle that street lamps work according to the different brightness of day/night, and obtains a novel model control method. While changing the traditional model control, several technical difficulties arise. Based on the problems in the prior art, the present invention proposes an optical signal receiving device, which can effectively improve the problems of the prior art, such as small light sensing receiving point, easy interference by other natural light, weak signal strength and single signal.

Invention principle:

The main function of the housing 20 in the present invention is to increase the laser receiving area, and the second is to reduce some disturbing light. In the selection of materials, the light transmission, concentrating and astigmatism of the materials are comprehensively considered, and the astigmatism is the most favorable for receiving. Among them, the main principle of material selection is light scattering: the light beam passes through an uneven medium, and part of the light beam deviates from the original direction and spreads, and the light can also be seen from the side.

In addition, light intensity is a physical term that refers to the luminous flux of visible light received per unit area, referred to as illuminance. The illuminance of the laser pointer used in the embodiment of the present invention is slightly weaker than that of the sun in winter. Therefore, it is necessary to let the light of the laser pointer reach the photosensitive electronic element 31 to realize the conversion of optical signals into electrical signals and transmit them to the programmable controller. The laser pointer is However, since the photosensitive electronic element 31 is very sensitive to light, in order to reduce the interference of other light, the thickness of the shell 20 can be thickened. The weight of each receiving device is reduced; the filter that matches the light species of the laser pen is used to screen the effective light species among the seven colors of light. Among them, the filter uses different colors of light with different wavelengths to select the light species. There are seven colors of visible light: red, orange, yellow, green, indigo, blue, purple, corresponding to the wavelength range of 625-740nm, 590-610nm, 570-585nm, 492-577nm, 420-440nm , 440-475nm, 380-420nm, choose the filter according to the light color of the laser pointer, which can greatly reduce the interference of other light.
