Vibration monitoring system, vibration monitor for wind power station(Version for Wind power station)
1) High reliability
- Fully Integrated structure:integrates with signal conditioning,power supply,data processing and communication module, without wearing parts such as hard disk and fan.
- IP65 Protection grade:The on site collection box of RH1000 has dustproof and waterproof protection grade IP65, ensured the collection box can be used on industrial site for long time, defended influence of dust and smeary.
- Design of the lower consumption:Application of industrial ARMl chip, greatly reduced the heat emission of hardware, can work in high temperature industrial field without cooling fan assembly. Avoid the situation of much high temperature caused by PC104.
- Hardware protection:Application of firmware and watch dog circuit, ensured system stability; avoid the damage of computer viruses
- LCD: System implemented 5.7 inches LCD, users can browse the working status and data dynamic display of system on site, .
- Completed self-checking function:Modularity application design, can inspect every independent part of the condition, and present the exceptional report to the software system in time.
2) Accurately and completely data collection.
3) Realize synchronous sampling at any two channels
