Abstract

본 발명은 마이컴을 사용하여 시스템의 동작을 제어하는 전기기기에 관한 것으로서, 종래에는 메모리부는 전기기기 외부에서의 동작제어 프로그램 변경이 불가능하며, 전기기기 분해후 상기 메모리부의 고체를 통해 동작제어 프로그램의 변경이 가능하므로서, 생산성 동작 제어프로그램이 일부 기억 영역에 내장되어 상기 메모리부(2)의 효율이 떨어지며, 상기 전기기기가 제작된 시점에서 결정된 제어 프로그램의 수명이 다할때까지 사용해야 하는 불편한 문제점이 있었다.The present invention relates to an electric device that controls the operation of the system using a microcomputer, and in the related art, the memory unit cannot change an operation control program outside the electric device. Since it is possible to change, the productivity operation control program is embedded in a part of the storage area, so that the efficiency of the memory unit 2 is reduced, and there is an inconvenient problem of using it until the life of the control program determined at the time when the electric device is manufactured. .

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 마이컴을 사용하여 시스템의 동작을 제어하는 전기기기의 내부 프로그램을 전기기기의 분해나 메모리의 교체없이 변경될 수 있도록 전기기기에 외부의 연결단자를 연결하여 시스템에 동작제어 프로그램을 변경 또는 수정시키고, 상기 동작 제어 프로그램을 생산성 제어 프로그램의 일부 기억 영역에 우선적으로 기억시켜 제품을 생산하므로서, 전기기기의 출하시 시스템의 목적에 적합한 프로그램의 변경이 가능하며 메모리의 효율이 향상되고, 전기기기의 선생산후에 시스템의 기능을 가변시킬 수 있어 제품의 개발기간을 충분히 얻을 수 있는 동작체계(SYSTEM) 가변형 전기기기 장치 및 전기기기의 내부 프로그램 변경방법이다.Accordingly, the present invention is to solve the above problems, the internal program of the electrical device to control the operation of the system using a microcomputer to be changed without disassembling or replacing the memory of the electrical device, the external connection terminal to the electrical device By connecting or changing the operation control program to the system, and producing the product by first storing the operation control program in some storage areas of the productivity control program, it is possible to change the program suitable for the purpose of the system at the time of shipment of the electric equipment. In addition, the efficiency of memory is improved, and the function of the system can be changed after the production of electrical equipment, so that the development time of the product can be sufficiently obtained.
