technical field

The utility model relates to a switch, in particular to a remote intelligent timing control switch based on a GSM network, which belongs to the technical field of the Internet of Things.

Background technique

The intelligent control of home appliances has become a new trend of social demand, and the intelligent home appliances based on the microcomputer control system make our life more convenient. And whether it can realize the switch control of remote home appliances has become an increasingly interesting research direction. Household electrical appliances have entered a mature and stable period, and the market size is steadily increasing. However, competition is becoming increasingly fierce. The performance and quality of its core components, namely controllers, have a great impact on enterprise products. At the same time, with the rapid economic development, people have higher and higher requirements for the comfort of family life, especially in the convenience of home appliances. In this context, the home appliance control system that can be controlled independently has gradually shown its competitiveness, which is also in line with the objective needs of the development of the times. With the rapid and steady growth and rapid development of China's economy, home appliance manufacturers are increasingly aware of the importance of home appliance controllers, which are called "chips" for home appliances. Therefore, they have cooperated with professional R&D companies or manufacturers to develop industry-leading controllers that meet market demand. At present, there are many research and design proposals on home appliance controllers, such as: infrared remote control, voice recognition and so on. However, there are generally disadvantages such as small controlled distance or space (limited to indoor or outdoor environments with very limited coverage) and difficult voice recognition, so the use efficiency is low.

The existing ordinary switch can only realize the switching function by directly touching its control terminal; although the radio frequency switch has realized a certain remote control function, it is limited by a certain space and does not have the advantages of remote control and timing control; at present, professional timing switch control at home and abroad The main implementation methods of the controller are simple timing controllers based on special timing ICs, or using PLCs to form industrial equipment timing controllers. Nowadays, most merchants use microcomputers (that is, single-chip microcomputers) to control them by touch. Design the power switch program to realize the timing switch control. With the increasing data processing and storage capacity of single-chip microcomputers and the mature application of liquid crystal display technology, the functions of various timing controllers on the market are also constantly improving, and the degree of intelligence is also getting higher and higher!

The Internet of Things technology is a research hotspot of next-generation network technology, and has been promoted to the national strategic level by the Chinese government to give key support. Due to the limitations of technology and cost control, the Internet of Things technology is not yet fully mature, but various local and small-scale Internet of Things technologies emerge in endlessly and develop rapidly.

In view of the above situation, whether it can be combined with the Internet of Things technology to design and produce a new type of remote timing control switch has opened up a new way of thinking for those skilled in the art.
