Secured Multi Channel Wireless Temperature Monitoring and Controlling System for Moulding Process

In this paper we achieved the secured automation in temperature control and also power wastage diminishing in heater coils of electric heater based machineries. In this concern we handled the technique in shell molding machineries. The most important considerations in this paper are low cost, long life and high efficiency. In this work the system uses a single temperature controller with four channels and K type thermocouple for measurement. Moreover the system uses Zigbee for secure communication between the system and the server. This method achieves a temperature error of plus or minus 6 degree Celsius, and the acceptable range for the foundry industries is plus or minus10 degree Celsius. This system provides temperature monitoring and controlling of the process and provides the means to evaluate the equipment's current condition and detect the failures in thermocouples and the heater coils at an early stage. The system software at the server can be used to monitor and control the temperature set point, temperature upper and lower limits with authorized access.
