【正文】 s ability to control, so in the design of household appliances infra red remote control, wireless remote control as unnecessary, each set (transmitters and receivers) have different frequency or remote coding (Otherwise, wall will control or interference with neighbors household appliances), all similar products in the infrared remote control, The same can control the frequency or coding, and no remote control signal drop. This universal infrared remote control provides a great convenience. Infrared to visible light, is very subtle and confidentiality, therefore, the security, Alert and other security devices have been widely used. Infrared remote control is simple in structure and easy, lowcost, antiinterference capability, high reliability are a number of advantages, is a closeup remote control, especially in indoor remote control optimized manner. Conclusion Infrared remote control system based on protocol of infrared remote control technology is widely used in various household appliances and entertainment facilities based, provide convenient means of control for the user. But ordinary infrared remote control system has two shortings: (1) the remote controller is specially, and the use of remote control protocol, instruction oriented protocol is simple, not suitable for systems with plex protocol。 Highspeed mode : The maximum rate of 16 Mbps. Also according to the size chip power consumption can be divided into low power consumption and standard two categories, lowpower type normally used 3 V power supply, transmission distance closer to about 0 30cm, which is monly used standard 5V power supply, transmission distance away at least 1m above. infrared remote control transmitters of the status quo at home and abroadInfrared Infrared munication technology in the development stage and there are several infrared munication standards, between different standards for infrared equipment can not infrared munication. To have all the infrared equipment to interoperability in 1993 by more than 20 large manufacturers initiated the establishment of an Infrared Data Association (IRDA) unified the infrared munication standards , which is currently widely used in infrared data munication protocols and standards, also known as the IRDA standard. Since 1993 IRDA since the establishment of the Infrared Data Association members have developed to more than 150. IRDA standards of the industry has been widely recognized and supported. Has been developed with the infrared munications equipment have been as many as 100 species. IR module, ins
