Abstract: | The design and implementation method of a digital frequency-voltage emergency control equipment is presented in this paper, in order to improve the reliability and measurement accuracy,32-hit embedded microcontroller are used as the core control chip in the equipment, dual-voltage circuit are designed for voltage measurement, hardware and software are combining for the frequency measurements, a number of different conditions are setting for any failure judgment and decision-making, multi-locking mechanisms are used to prevent malfunction and refused to move effectively. Voltage, frequency and other information are display on large-screen LCD in real time. Embedded network communication interface are using international standard communication protocol or aecording to customer requirement. |
