One-chip computer multi--distance warm and humidity
control system design
Abstract: In this paper, the inspecting system has the functions of temperature and humidity measurement.
This system is controlled by a two-level computer, and it is a distributed inspecting system with a principal and subordinate structure. It takes Personal Computer as the main computer and Ling yang single-chip micro-controller as the subordinate frame. The fore part of data acquisition is including: (1) adopting 1-wire digital thermometer DS181B20 to measure temperature; (2) adopting capacitive humidity sensor HSI101 to measure humidity. Show that uses the liquid crystal module of 16 words of 2 lines partly. Pronunciation report part utilize SPCE061 one-chip computer have pronunciation report function is it realize to come. Executive body through control air blower or relay of dehumidifier achieve the goal of controlling the temperature and humidity part.
The subordinate computers communicate with the main computer through the serial bus.
The system software uses the design of software engineering to realize the structure of the program and the modularity of the functions.
Key words: single-chip micro-controller；temperature and humidity measurement；system
