This system took LPC2132 chip of PHILIPS as its main processor, including temperature pressure frequency and swing analog circuit and step motor driving module. By transplanting μC/OS-Ⅱ embedded real-time control system on hardware flat, it achieved real-time collection of several signals and display. This system is of high precision and efficiency. It meets users’need for ultrasonics dental descaler measuring well with wide market prospect.
