| Abstract: | This design, taking STC89C52RC single-chip with ISP function as the core, constitutes the smallest system by using the most popular devices, converts chip ADC0809 by external extended modulus and acquisits temperature by adopting temperature sensor ADS90. It collects changes of electromotive force through the method of motor opposite connect sensing coils so as to measure the elec- trical air gap and reserves all interfaces by jumpers. The entire experiment board structure is clear and the function is practical, which has the advantages of high performance-price ratio and simple use. Also, the design contains the modules such as analog input, digital input, human-computer interaction, serial communication, power supply module circuit, LCD liquid crystal display circuit and so on. It is a good choice to apply to the intelligent monitoring of power transformer. |
