Introduction • STMS – Surface Temperature Monitor Surveillance • Hardware specifications for RFQ task • 1Wire/EPICS Integration IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012
STMS – Surface Temperature Monitor Surveillance • 1-wire system • 1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012
STMS – Surface Temperature Monitor Surveillance • Hardware solution for IFMIF RFQ test bench: • Network Interface: LinkHub-E ethernet interface • manage up to 4 sensor lines • Temperature sensors: T-String Temperature Sensor • 6 temperature sensors • total length: 2.44 m (8 ft) • temp range: -55/+125°C • accuracy: ±0.5°C in [-10,+85] °C • resolution: 12 bit • conversion time: up to 720 ms • No signal time propagation and communication problems will be affected in this configuration IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012
