The Develop And Exploation Of NC Filming Machine

Varied filming machine,s requirement becomes bigger and bigger go with the rapid development of electron,architecture,chymistry,scientific research,accordingly filming machine appear. Nitrocellulose is called"NC".It is used wiedly in the domain of biology and medicine, especially it is important for experimentation of albumen snd nucleic acid. Nowadays, there are many kinds of filming machine in the market. It is critical for filming machine with the development of micro-electronics, MCU control technology and network technology especial for the stabilization and equality.This paper introduce the theory of filming machine. We chose the series of full-scale function AT89S52 MCU and some driving chip and other peripheral circuit. Carry through the PCB design and programming,achieve the control of motors commendably and filming steadily, improve the demand of fiming accuracy,make the filming machine have better reliability,offer reliable quality guarantee for consumer; solve the unsettled problem existed before radically.According to the system-designing method of modularization, we divide the hardware into some circuit modules and then testing and emulating the whole circuit. Similarly, we divide the software into some program modules. And then debug the program in a whole. Finally, we test the heat meter as a whole system in the functions.According to experiment, the system gets the purpose of filming steadily and accuracy. The structure is reasonable. Hardware and software are working steadily. For the future, we should pay more attention to multifunctional filming machine and the security of filming.
