Abstract
The paper has studied the water and water heat transfer unit's design question, This plate heat exchanger units collect heat interchanger, monolithic integrated circuit, sensor, monitor, frequency changer, circulating water pump in a body. It Completes data gathering, processing, the demonstration, and can through change the water pump’ current capacity in a time side, controls return pipes the water temperature in two time side, enables its temperature to achieve the industry the demand value.It has studied unit's intelligence control system with emphasis. This topic research goal is realizes the unit in the situation which nobody value defends, may according to the different operating mode condition and user's daily schedule, the reasonable movement, achieves the best heating and the energy conservation effect. topic design hardware electric circuit including four big modules: (1) The data acquisition module: Realizes related temperature signal gathering and the enlargement, and carries on the mold --number to the signal to transform, forms the digital signal; (2) monolithic integrated circuit regulation module: The logarithm carries on analysis processing according to the gathering partial outputs digital signal, according to the related procedure which establishes has formed the regulative signal, transmits are partial to the implementing agency; (3) person and machine interactive module: Realizes the correlation temperature signal real time display, is advantageous for the real-time monitor ;(4) regulation carries out the module: Accepts the monolithic integrated circuit regulation partial outputs the regulative signal, realizes under the monolithic integrated circuit control to the related current capacity regulation.
Key words: Sensor, monolithic integrated circuit, monitor, frequency changer
