Extremely accurate real-time clock chip DS3231 and its application in multi-rate Watt-hour meter;

application of real-time clock chip in Real-time Monitoring System;

Serial Real-time Clock Chip S-3530A and Its Application In51Single Chip Microcomputer System;

Application system design with DS1306 real time clock and PIC microcontroller

The power manager unit and the node s sleep period are controlled by an RTC(real time clock) chip.

At present time-controlling is used extensively in most of application system,this paper discusses the timing, alarm clock and the square wave exporting functions of DS12C887 combining with the type and the characteristic of the RTC(real time clock)chip and the applicative circuit.

High Performance Crystal Oscillator for RTC;

The RTC module is a typical char device as well as an important part of Industrial Control System.

The real-time measurement of the tuning fork forced vibrations by computer;

Real-time measurement of the object angular vibration by laser speckles;

To avoid these defects,using elliptic fitting technique,a non-contact real-time measurement system based on grid strain was established.

Power system operation reliability evaluation system based on real time measure;

This paper makes an inquiry into realizing a method to real time measure wantonly many spot field intensity of space symmetrical dynamic field with a small number of sensors.
