Intelligent home system based on wireless control and communication anti-collision algorithm thereof

Abstract

The invention relates to an intelligent home system based on wireless control. The intelligent home system comprises a central control module, an intelligent access control module, an intelligent light control module, an intelligent water heater control module, a smoke sensor module, a wireless transmission module and a power module, wherein the intelligent access control module, the intelligent light control module, the intelligent water heater control module and the smoke sensor module are separately connected with the power module; the intelligent access control module, the intelligent light control module, the intelligent water heater control module, the smoke sensor module and the power module are separately integrated with a zigbee module chip, and communicate with the wireless transmission module; and the wireless transmission module exchanges data with the central control module via a UART (Universal Asynchronous Receiver / Transmitter) interface. By adopting the intelligent home system, users can enjoy a more humanized, high-quality and intelligent living mode and remotely control intelligent home furnishing in real time, the receiving problems of packet loss, collision error and the like in data transmission are reduced, and the data transmission is more reliable.

Description

[technical field] [0001] The invention relates to the technical field of communication electronics, in particular to a wireless control-based smart home system and a communication anti-collision algorithm thereof. [Background technique] [0002] With the rapid development of computer, communication and microelectronics technology and the improvement of people's living standards, people's requirements for the living environment are also pursuing the ideal goal of spiritual connotation, safety and comfort, convenience, intelligence and automation. The intelligent home environment is also Gradually attract people's attention. At present, in the existing smart home design, the connection between the control center and the terminal equipment is mostly based on the wired connection method based on the bus, such as 485, CAN, etc. This method is not only complicated in construction, but also extremely inconvenient in maintenance. In addition, although wireless communication is also...

Problems solved by technology

At present, in the existing smart home design, the connection between the control center and the terminal equipment is mostly based on the wired connection method based on the bus, such as 485, CAN, etc. This method is not only complicated in construction, but also extremely inconvenient in maintenance.

In addition, although wireless communication is also used, if multiple terminal devices are sending data to the control center at the same time, data collision and loss will occur
