Smart home open source hardware development platform

Smart home products have been quickly integrated into our lives, such as being woken up by soothing music in the morning, smart lights that can be controlled at will, central control, a system that turns on lights when people arrive and turns off lights when people leave, smart door locks, visual Intercom, etc., these all play an important role in our lives. Smart home can usually be set as a comprehensive management system, which has the characteristics of intelligence, informationization, energy saving and humanization.

At present, the more famous smart home systems include the Mijia system launched by Xiaomi (centered on smart hardware and mobile APP made by Xiaomi), Apple’s HOME⁃KIT (authorized third-party manufacturers to produce compatible smart hardware) and so on. Large companies such as Xiaomi and Apple have strong technological advantages, and their smart home products have initially formed a certain market size. In recent years, a large number of open source programs for controlling home appliances have appeared in the field of network open source hardware. Using the built-in class library, you can develop a simple mobile phone to control LED lights or realize remote control of air conditioners with mobile phones; there are many in the smart home community forum. Smart home reference case. However, the means of realization are varied and fragmented. As far as communication methods are concerned, there are Bluetooth communication, WiFi communication, zigbee communication, serial communication and so on. This paper selects an open source platform for network hardware, thereby reducing the difficulty of programming and quickly realizing an intelligent smart home system.

This article will focus on building a home appliance control platform, using an open source hardware platform to control indoor lighting, temperature, humidity and other parameters through mobile APP. Smart home is currently a nascent industry with development potential. In the future, with the further implementation of the promotion and popularization of smart home products, consumer demand will become more diversified and intelligent. Therefore, the consumption potential of the smart home market must be huge, and the industry has a bright future.

Smart home control system based on hardware open source platform

The smart home system integrates various conventional technologies (such as intelligent control technology, linear system technology, wiring technology, network technology, audio intelligence technology, etc.) to implement organic integration, and continuously improves the simplicity and convenience of the smart home system. The main technical solution of the smart home control system based on the hardware open source platform designed in this paper is to first complete the construction of the network open source hardware platform, and at the same time write the open source control program and the control software for the mobile phone. The hardware composition of the system is: control board, sensor module, household appliances, relay/wireless switch/smart socket module (for controlling non-infrared remote control appliances), infrared signal transmitting module (for controlling infrared remote control appliances), bluetooth module ( Used to build a Bluetooth intranet), sensor module (to collect indoor information), WiFi module (to connect to the external network). The working principle of the whole product is: the sensor collects indoor information and transmits it to the main board, interacts with the mobile phone through the external network, returns command information, and transmits the information to the infrared information emission module and relay/wireless switch/smart socket module through the Bluetooth internal network, thereby controlling home appliances . The Bluetooth intranet consists of the main board (upper computer), lower computer, and HC-05 Bluetooth module. The open source hardware platform and the Bluetooth module are connected through a serial port, and wireless communication is performed between the Bluetooth modules. For different functions, rationally use the open source class library on the network. When developing the mobile terminal, we will carefully study the design of the humanized operation interface, try to make the software easy to use, better control the cost of software and hardware, and easily achieve low price and high performance. Superior smart home system.

The smart home system based on the open source hardware platform designed in this paper has many advantages and characteristics, as follows: 1) Using the network open source hardware development platform, the cost is lower, the development cycle is shorter, the program modification and debugging are easier, and the development of new functions is also relatively easy. Convenience, less difficulty in later software maintenance. For example, if the open source board of the product's development hardware breaks down, users don't even need electronic technology foundation, just follow the prompts to buy a new board and burn the program to the board according to the instructions. 2) The combination of long-distance communication and short-distance communication, wired communication and wireless communication can flexibly adjust the number of lower computers and upper computers, and improve the indoor network structure. Avoid security issues caused by a single communication method. 3) There is no need to purchase expensive supporting smart home appliances, which has strong adaptability and greatly reduces consumer spending, especially when there are many electrical appliances in the residence. Not only can it be controlled on the mobile phone, but also can be controlled by accessing the website through the computer. Compared with the Mijia system and the HOMEKIT system, it is more flexible and convenient.

epilogue

This paper designs a smart home system based on an open source hardware platform, and realizes a new home life experience through networked comprehensive intelligent control and management. According to the new-generation artificial intelligence development plan issued by the State Council, by the end of 2020, China's main industrial value in artificial intelligence (AI, Artificial Intelligence) related core fields will reach 1 trillion yuan, driving the scale of related industries to exceed 10 trillion yuan. Among them, home furnishing, as one of the industries most closely related to the daily life of the public, is undoubtedly a focus of the development of the artificial intelligence industry. Smart home products have now become an important trend in the development of the home industry. The continuous improvement of the technology level of smart home products and the continuous accumulation of installation technology can allow more users to see the high-quality performance of smart products.
