Advanced Water Irrigation System
This paper represents a Mechatronics system used for advancedwater irrigation. This system is integratedwith three basic elements namely,sensing unit, controlling unit and actuating unit. Sensing unit consists of YL-69 water sensorsalong with YL-38 bridge circuits.Controlling unit consists of 8 bit microcontroller and SIM-900 GSM module. Actuation unit consists of DC motor operated valves assistedwith driver circuits. Thisautomatedwater irrigation system can be operated remotely usinga mobile phone. The information about the required field to be irrigated can be sent through a registered mobile number,in the form of SMS. GSM module receives a message and there after sends set of instructions to microcontroller through MAX-232 communication device. Microcontroller is so programmed that,on receiving the instructions from GSM module, it decides which valve to be operated usingcorresponding DC motor
Feedback Assisted Closed Loop Inspectioncontrol System
This paper is intended to focus on the advanced measurement system, developed for accurate measurements of, dimensions of, a valve guide of an engine. Snap gauges, pneumatic comparators, dial gauges, micrometers, etc are traditional instruments used for inspection. These methods may lead in inaccurate job inspection. So, to overcome the drawbacks associated with traditional equipments, one can develop an advanced measurement system using sensors, actuators and control system. The sensing unit of this system consists of two LVDT probes. Control unit is a programmable logic controller (PLC), while actuation unit has electromagnetic relay and a display. Along with this, a mechanical fixture mounted with LVDT probes is used to hold the job to be inspected. A job to be inspected has to be kept on mechanical fixture. Two LVDT probes which are fixed on fixture displaces as per the job profile. These LVDT sensors are integrated with control unit though an amplifier. Control unit is also integrated with display and a relay. Depending upon the signal received from LVDT, control unit decides which data has to be displayed and whether a relay is energized or not. The relay has control over the machine cycle
