The main goal of this project is to design and implement an automated industrial monitoring and control system that can monitor the excess load, variations in temperature, and excess vibrations from the machines.
Industrial control system (ICS) is a general term that encompasses several types of control systems, including supervisory control and data acquisition systems, distributed control systems ( DCS ), and other smaller control system configurations such as skid-mounted Programmable .
ICSs are typically used in industries such as electrical, water, oil and gas, data. Based on information received from sensors, automated or operator-driven supervisory commands can be pushed to remote station control devices, which are often referred to as field devices.
Field devices control local operations such as opening and closing valves and breakers, collecting data from sensor systems, and monitoring the local environment for alarm conditions.
GPRS Based Industrial Monitoring project consists of the following blocks - GPRS module, transformers, sensors, microcontroller, relay circuits, amplifier, keypad and display (LCD).
The transformers are connected directly to the load. The transformers monitor the variations in the load. The current transformers and voltage transformer monitors the current and voltage respectively.
There output of the transformers is amplified and fed to the microcontroller. There are also temperature and vibration sensors that continuously monitor the temperature and vibrations respectively.
The sensors output are also fed to the microcontroller. The microcontroller is programmed using Embedded C and is designed to take actions based on the output of sensors and transformers.
The controller we use is a 16 bit 16F series PIC microcontroller. Based on the sensors and transformers output the controller drives the relay circuits. There is a LCD for display and keypad for input interfaced to the controller.
This system also offers extra features such that the commands from the system can be sent through the GPRS from the remote location. The user can log onto to the server from the distant location using his user name and password. As soon as he logs on the user is authenticated to send commands to the remote location for control. The backend sever design is built on the jsp platform. The GPRS module receives this data and makes necessary control mechanisms
