Abstract: This paper introduces the design and research process of wireless remote control transmitting and receiving devices. In wireless remote control transmitting and receiving devices, the traditional method is to use dedicated wireless remote control transmitting and receiving chips, such as NB2262 and NB2272, but with various restrictions, so directly The EM78 series single-chip microcomputer is used to replace the two types of chips to form a wireless remote control transmitting and receiving device. On the other hand, as the main controller of the lighting system, a new type of intelligent lighting system is formed on the basis of this, and finally the software identification wireless is given. The method of remote key code and the corresponding program flow chart.
1 Introduction
Lighting systems are closely related to people's lives, but most of today's lighting systems use all kinds of ordinary switches to turn on and off the lamps. The brightness adjustment of the lights is also adjusted by ordinary dimming switches. Every time the lighting system is operated, it must go to the switch to complete, and a switch can only correspond to one luminaire, which requires a lot of switches to be installed. Therefore, it is very necessary to produce a wireless remote control transmitter that integrates dimming and switching. The receiver, which will allow people to switch and dim the lighting system freely from anywhere, based on this idea, the author's research institute and MasterCard Switch Company jointly designed a new type of wireless remote control intelligent lighting. System, the following is a detailed introduction to the research and design process of several important components of this system.
2. Research and design of wireless remote control transmitter
In recent years, integrated chips for various wireless remote control transmitters have been produced, such as the NB2262 produced by Ningbo Jingjing Co., Ltd. However, remote controllers using such chips have many disadvantages, such as a fixed number of address codes, which are prone to occur. Repeated transmit signals, in addition to using the chip, it is more difficult to transmit continuous signals. Due to the above shortcomings, the general transmitting chip is not suitable for the remote control of the intelligent lighting system. Therefore, the EM78P153 single-chip microcomputer of Yilong Company directly adopts the remote controller of the intelligent lighting system, and its schematic diagram is shown in FIG.

Exhaust Fan, driven by the fan to rotate the air flow, so that indoor and outdoor air exchange of a class of air-conditioning appliances. Also known as ventilation fan. The purpose of the exhaust is to remove the indoor dirty air, adjust the temperature, humidity and sensory effects. Exhaust fans are widely used in homes and public places.
Exhaust fan, also known as negative pressure fan, negative pressure fan and so on. Is the use of air convection can make the room has been in a negative pressure state, the formation of a suction, a steady stream of outdoor air, and exhausted indoor hot air, so as to achieve ventilation and ventilation, cooling effect.
