Online monitoring system for wind turbines
1) High reliability
Fully Integrated structure:integrates with signal conditioning,power supply,data processing and communication module, the heat emission of hardware has been decreased significantly, without wearing parts such as hard disk, fan.IP65 Protection grade:Dustproof, defending greasy dirt, robust casing for industrial and hard everyday use.Design of the lower consumption:Application of ARM industrial chip, helping to sharply reduce the heat emission of hardware, can work in high temperature industrial field without cooling fan assembly. Avoid temperature rise too much in case of adopting some add-in cards such as PC104 ad so on.Hardware protection:Application of firmware and watch dog, guarantee system is more stable; avoid the damage of computer viruses.Completed self-checking function: Modularity application design, can inspect every independent part of the condition, and present the exceptional report to the software system promptly.2) Accurately and completely data collection.
Widely dynamic range:24bit A/D converter, plus 2048 times amplifier in signal conditioning, so system gain is greater than 110 dB. Ensured the accurate collection of mV level signal.Widely analysis frequency span, powerful calculation capability: maximal analysis frequency is 20 KHz, and independent of channel number. RH1000 capable of implementing high computational burden algorithms such as FFT processing, maximal lines is 6400.Plentiful modulation function: Acceleration transducer can obtain the signal of acceleration, velocity, displacement after once or twice integral to the original signal.“black boxes”:Systems offers multi event trigger for record function, any data user cares about can be recorded; user can specify the data length before and after activating triggers.3) Realize synchronous sampling at any two channels
4) Good scalability
