in view of the substation equipment temperature measuring work, the existence of low accuracy of temperature measurement, data real-time performance, large work volume on manual operation, the temperature of the wireless sensor monitoring technique, the 2.4 GHZ wireless network technology, build a wireless temperature monitoring system, substation equipment temperature and the temperature rise of accurate, reliable and real-time on-line monitoring. Real-time monitoring data, intuitive display are in tabular and graphical form. Have the equipment temperature measurement data, temperature change trend analysis, data query and management, over temperature alarm to remind, etc. Real-time temperature data can be convenient access to the substation set control center, to ensure safe and reliable operation of the transformer substation, for substation monitoring and maintenance of equipment operation to provide data support, effectively prevent substation equipment oxidation, burning and other accidents.

In this paper, a temperature monitoring system for glass manufacturing process is proposed by using Fibre Bragg Grating (FBG) approach. This system can be done by using OptiSystem simulation. FBG was used as it allows a reflects a wavelength of light that shifts according to variations in temperature. Generally, FBG sensors can be easily installed, it has higher accuracy, longer stability, small in size, immunity to electromagnetic interference (EMI) and the ability to measure ultra-high and speed events. The results indicated that wavelength shifting is depended on thermal expansion coefficient and thermo-optic coefficient of materials, from simulation results it was seen that, Tungsten DiSulfide(WS2) has a better sensitivity than Silica, Poly Methyl Methacrylate(PMMA) and Lead Sulfide(PbS).
