What are the five wireless technologies commonly used in smart homes?
1. Bluetooth
Bluetooth can enable the terminal to actively release, acquire and process information. With the development of Bluetooth technology, Bluetooth can control all information devices through remote control, and even share useful information among Bluetooth information appliances. The Bluetooth module uses the Bluetooth transmission module of Bluetooth wireless technology, the communication network environment of the Bluetooth module, and the contact with the operating system. It plays a very important role in the smart home system, and its development process has attracted great attention in the industry. The demand for smart home appliances is constantly increasing, and the demand for Bluetooth modules is rapidly increasing.
2. ZigBee
Generally speaking, the intelligent home appliance control system using ZigBee technology includes ZigBee coordinator, ZigBee infrared control terminal and home gateway. There are two functional modules in the ZigBee network, one is the ZigBee coordinator for the establishment and management of the ZigBee network, and the other is the ZigBee terminal node. The control is mainly to connect the ZigBee network and the learning infrared remote control module. The ZigBee coordinator communicates with the home gateway through the RS232 serial port to realize the connection between the wireless control network and the control host.
At present, most of the products on the market are home smart Wi-Fi wireless networking technology to realize the intelligent control of home appliances. The main principle is that the program instructions are issued by the user's own mobile phone, and the unattended system module in the house receives the appropriately processed information, and transmits the processing results to the single-chip microcomputer through Wi-Fi, and the single-chip microcomputer issues corresponding control according to the control commands. Instructions and other information to complete the user at the same time, and also return the final result to the client. The main function of the client is the intelligent control of home appliances, that is, the client sends control information to the server through the Wi-Fi network, and then feeds the information back to the client through the server.
4. Infrared
Red transmission, traditional household appliances, are basically used in infrared transmission. With the development of smart appliances, large refrigerators, small electrical outlets, all labels are attached to the smart moment. Infrared is also a way to realize the intelligent upgrade of home appliances, mainly relying on wireless infrared transponders. The wireless infrared transponder is a built-in infrared transceiver module. It has infrared signal learning and memory functions, and can learn and memorize intelligent products of various infrared devices. It can be a ZigBee wireless transceiver module, the correlation of wireless signals and infrared signals, household appliances are controlled by mobile smart terminals using any infrared remote control, through wireless infrared repeaters, home applications provide users with smart applications in any Mobile phone, remote control of multiple electrical equipment, and realization of various infrared remote control functions.
5. RF
RF contains RFID tags, which is a non-contact automatic identification technology, and obtains relevant data, and uses radio frequency signals to identify objects without manual intervention. As a wireless version of the barcode, the barcode technology RFID is not waterproof, antimagnetic, and durable High temperature, long service life, large reading distance, data on the label can encrypt the storage capacity of the data, and the freedom of storing information is more advantageous. RFID RFID tags are considered to be widely used in smart refrigerators, eventually replacing the bar codes that need to be used today. Each RFID tag represents a unique number for each product, rather than tracking the product as a barcode for the entire product. You can connect the processing data to the network through the rfid reader to determine the product name, manufacturer, validity and all other relevant project information.
