Description

Radio remote control address programmable two-way communication digital lighting control device

Technical field

The utility model relates to a radio remote control device, in particular to a radio remote control address programmable two-way communication digital lighting control device.

Background technique

At present, the switch control of the light generally adopts a mechanical switch, which is fixedly installed on the wall, and its on or off state is controlled by pulling or pressing. The dimming of the light is composed of potentiometers, thyristors and other components, and the conduction angle of the thyristors is adjusted by rotating the potentiometers for dimming. There are also some dimmers with analog voltage 1-10V or 0-5V interface, and the dimming can be realized by adjusting the potentiometer to adjust the voltage. Products with wireless remote control and programmable timing to control lighting are rare. In the field of radio remote control, the common means of radio remote control are generally two kinds of infrared rays and radio. In the general control field, the encryption method of the radio remote control is to use a dedicated encoder and decoder integrated circuit, and its I/O port or address line is connected to the air or ground or connected to the power supply (three-state connection) according to different connection methods. To achieve, or by the dial to achieve address allocation. The I/O port or address line of the encoding integrated circuit of the transmitter and the I/O port or address line of the decoding integrated circuit of the receiver must be connected in the same way, which is a one-to-one correspondence. In many electronic products with radio remote control, the remote control (hereinafter referred to as the transmitter) controls the receiver by transmitting control signals. information to inform the remote control that the remote control is successful.

The on or off control technology of the above-mentioned lamp is simple, but because its installation position is fixed, you have to go to the switch when operating the switch, so it is very inconvenient to switch the lamp, and it is not easy to change its installation position once it is installed ;Potentiometer-type dimming is intuitive and easy to use, but the potentiometer has mechanical contact and mechanical wear after all, and it is easy to wear or even damage over time; the above encryption method uses encoder and decoder integrated circuits, which are costly and occupy a lot of I/O For port or address line resources, the number of passwords obtained is small, so passwords are prone to overlap and are easy to crack. Since the decoding integrated circuit on the receiver is paired with the encoding integrated circuit on the transmitter, that is, their three-state connections must correspond one by one, so the processing can only be one-to-one processing and packaging. Processing, production, and sales bring a lot of trouble. This password setting method, once the password is set, it is not easy for users who do not have professional tools to modify it. If one of the receiver or the transmitter is broken, both of them have to be scrapped (now There is such a product in the market), it is a kind of waste for users, so it cannot be promoted. Moreover, this point-to-point control method, when the receiver receives a valid signal, the receiver emits a sound or uses a light indicator to notify the received signal, so the remote control can only be used for remote control that is relatively close or within the range that people can perceive , If the remote control is far away or next door, it is difficult to know the result of the remote control.
