The measures and controls Power source
with Microprocessor protection
ABSTRACT:This text has introduce the principle of observing and controlling that the Single Chip Microcomputer protects, has carried on the designs of concrete hardware and software, aim at realizing the intellectual control and management of relay protection of the electric power system.
This system regards intelligent chip AT89C51 of ATMEL Company as the key processor on the hardware, carry on to is it deal with with various kinds of trouble protecting to gather in real time data mainly. Hardware adopt module design method, hardware circuit chooses standardization , module typical circuit as as possible, in order to expand..
System adopt many task operating system so as to ensure each PRI different tasks can the orderly execution in the order of priority on software design. Have guarantee the dependability and stability of the software, has met the real-time character demand for power system. The establishment of the software adopts the module programming method , every module is relatively independent, finish a certain specific function, easy to maintain and add the new function.
Finally , on AT89C51 one duplexing SCI serial mouth and EPROM all that itself have , propose computer and communication method of PC, in order to solve the system and external communication problem , the automatic control and centralized management of the implementation system.
Keywords: microprocessor protection real-time many task operating system relay protection Automatic control.
