Application of Microprocessors
Microprocessor microcontroller based systems may be used in almost every filed of life and their applications are increasing day by day at a very fast rate. For example it can be used to control the temperature of a furnace pressure of a boiler speed of an electric motor automatic control of generator voltage fuel control of furnace in a power plant military equipments like radars tanks etc lift control robot control etc.
The other uses of computer system need not to be discussed here as all of us utilise them in our daily life in banks schools colleges hospitals shops library hotels laboratory offices etc. The aim of this article is to explore the uses of simplest microprocessor like 8085.
Microprocessor deal with digital signals and the real world has analog singles . to interface microprocessor with the real world analog to digital converter and dice versa are required ( these converters are explained in chapter 10 in derail.)
Suppose for example we want to control the temperature of furnace using microprocessor ( see the block diagram shown in ). For this purpose we can use a sensor/ transducer which can sense the temperature of the device and convert it into electrical quantities like current or voltage ( analog signal). This analog signal is converted to its equivalent digital signal using analog to digital converter. This digital value of the temperature is then read by the microprocessor where it is checked by predefined values by the program running on the microprocessor. Then microprocessor may generate a control signal if the digital value of temperature is not within the predefined limit. This control signal may be converted to equivalent analog signal if required and corrective action will be taken by the control systems to bring the temperature within the predefined limit by controlling the factors affecting the temperature of the device.
