Wireless Sensor Network In Intelligent Household Data Acquisition System Application

In recent years, intelligent household in China development is rapid, permeate many aspects of daily life. For example, in lighting control, household appliances control, visible interphone system in intelligent household control technology, make living environment more comfortable and convenient, and the development of wireless sensor network for intelligent household's widespread popularization provides technical guarantee.This paper analyses the present situation and development of intelligent household, introduces the current trend of intelligent household common wiring way, expounds the related knowledge of wireless sensor network. On this basis, based on wireless sensor network design of intelligent household data acquisition system. This design intelligent household to indoor temperature and humidity control object, focusing on controlling tasks simpler situation, choose star-shaped network topology structure. In hardware, completed the design of wireless sensor network node, choose integrated temperature and humidity sensor complete data acquisition function, also with the function of frequency-field; Choose microcomputer as the microprocessor to collect data processing, and store up to complete the single-chip peripheral circuit design of interface circuit design, the keyboard, LCD display circuit, clocking circuit and reset circuit; Choose embedded wireless transceiver complete system of communication function, through logical interface circuit achieved with the MCU electrical compatible, completed the data communications between; This paper involves the device of power exists 3.3 V and 5V two power standard, choose different chips to achieve voltage transform, to reduce the overall equipment volume, the independent power design thought.
