1. FAULT ALERTING AND MAXIMUM DEMAND
CONTROLLER FOR INDUSTRIES
ABSTRACT
In this fast forwarded world we are trying to reduce the manpower and trying to
automate all the systems to improve the speed and also the accuracy. Here is an
excellent means of automation, where we are trying to measure the parameters such as
temperature, object identifier, and light intensity etc. For example, different
parameters are not only measured but also a message is announced through loud
speaker when there is a fault. The different sensors are placed in different zones in an
industry or it can be any place where you are interested to measure and maintain the
parameters. The sensed parameters are applied to the controller through transistor
logic where we can monitor all the parameters.
The monitored parameters are compared with the threshold values and the required
controlling done through the controller. Whenever the values of the given parameters
are exceeded when compared to the threshold level then the concerned parameter
value is high (suppose, if the temperature is exceed to 50 degrees, which is a threshold
value. Then the message, “temperature is high” delivered through the loud speaker)
message is delivered through the loud speaker.
