Description

An intelligent switch control system

technical field

The invention belongs to the field of switch control, and relates to an intelligent switch, in particular to an intelligent switch control system.

Background technique

In recent years, the Internet of Things technology has continued to develop, becoming another major technological innovation after the Internet. The smart home has become an important application field of the Internet of Things. The concept of smart home originated in the United States in the early 1980s, and it is called Smart Home. It involves many fields, such as communication network, system integration, home appliances, medical treatment, sensor devices, automatic control, etc. The development of smart home has gone through 4 generations, and the requirements of the fourth generation are based on the Internet of Things technology to achieve personalized functions according to user needs. Compared with ordinary homes, IoT smart homes not only have traditional living functions, but also provide information interaction functions, enabling people to control home devices at any time, making home life safer and more comfortable.

With the continuous improvement of people's requirements for the safety and comfort of the home environment, the demand for the application of Internet of Things technology to home life is also increasing. At present, there are many home products such as smart switches that can be automatically controlled by mobile phones on the market. For example, Oribo's smart socket achieves the purpose of intelligent control by embedding a WiFi module in the socket, but the WiFi technology it uses consumes relatively large power. In the smart home world, low power consumption is important. For example, Philips' Hue Lights smart LED lights use ZigBee technology to control the switch status and color brightness of LED lights through smart terminal devices. But because ZigBee communication is not supported on the smart terminal at present, it cannot be directly controlled, but a relay device is needed, which not only increases the cost, but also brings inconvenience. Low-power Bluetooth 4.0 technology is a short-distance communication technology that has low data volume, strong response to communication bursts, and can be customized according to requirements. Using this technology, it can effectively form a low-cost, low-complexity wireless body area network and Wireless personal area network, and the current Bluetooth 4.0 technology has been widely used in smart phone devices. Compared with the traditional bluetooth device, it overcomes the restriction that the master device connects to 7 slave devices, and the transmission distance can reach 50-60m.

In addition, the installation of more and more smart switches will become children's new "toys". When the parents are not at home, children operate the smart switches casually, which will reduce the service life of the switches and even cause danger.
