These temperature data measured by sensors are transmitted to the base stations via 2.45GHz ISM band wireless channel periodically. The base station will save and record these data. The host machine will periodically poll the base stations in roll via wired network connections over RS-485 bus (or CAN); Upon polling each base station will transmit the temperature data to the host through the network connection. Then the host will process and save these temperature data. By comparing the relative temperature rises between the equipment and the enviroment, between indoor air and outdoor air, the host machine can detect possible overheat situation and produces Early Warning Signal to alert operators to handle the situation. The host can further communicate with a backend control station on Ethernet, through IEC 61850 standard protocol; and the host can also use a standard relay to send the alerting signal to public measurement/control panel. Product Part III Application Examples 3.1 Temperature monitoring system in the Electric Power Substation Equipment monitoring points can be: cable connector, knife switch contact, switch contact, copper bar junction, reactor, arc suppression coil, capacitor etc.. 3.2 Switch cabin and equipment in steel plants Monitoring temperatures differences between inside and outside cabin. 3.3…
