GSM BASED SCADA IMPLEMENTATION USING MICROCONTROLLER PDF

This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay. This Relay gets activated whenever the electrical parameters exceed the predefined values. The Relay can be used to operate a Circuit Breaker to switch off the main electrical supply. User can send commands in the form of SMS messages to read the remote electrical parameters. This system also can automatically send the real time electrical parameters periodically based on time settings in the form of SMS.

The Relay can be used to operate a Circuit Breaker to switch off the main electrical supply. User can send commands in the form of SMS messages to read the remote electrical parameters. This system also can automatically send the real time electrical parameters periodically based on time settings in the form of SMS.

This also can be designed to send SMS alerts whenever the Circuit Breaker trips or whenever the Voltage or Current exceeds the predefined limits.

This project makes use of an onboard computer which is commonly termed as micro controller. This onboard computer can efficiently communicate with the different sensors being used. The controller is provided with some internal memory to hold the code. This memory is used to dump some set of assembly instructions into the controller.

And the functioning of the controller is dependent on these assembly instructions.

GSM based SCADA implementation using Microcontroller

Microcontrollers are also used in scientific, high technology, and aerospace projects. Microcontrollers are designed for small or dedicated applications. Some microcontrollers may operate at clock rate frequencies as low as 4 kHz, as this is adequate for many typical applications, enabling low power consumption mill watts or microwatts Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, remote controls, office machines, appliances, power tools, and toys. A microcontroller can be considered a self-contained system with a processor, memory and peripherals and can be used with an embedded system. Microcontrollers must provide real time response to events in the embedded system they are controlling.

Microcontrollers are also used in scientific, high technology, and aerospace projects. Microcontrollers are designed for small or dedicated applications. A microcontroller can be considered a self-contained system with a processor, memory and peripherals and can be used with an embedded system. Microcontrollers must provide real time response to events in the embedded system they are controlling. When certain events occur, an interrupt system can signal the processor to suspend processing the current instruction sequence and to begin an interrupt service routine ISR, or "interrupt handler". Embedded processors are usually used to control devices, they sometimes need to accept input from the device they are controlling.
