Adopting Dorun self-developed (independent intellectual property rights) high-performance embedded software real-time operating system, it is applied to water and electricity, gas and heat information collection, and its uplink communication method and downlink communication method can be compatible with a variety of devices.
It also supports the combined use of four meters in one, wireless meters and wired meters, and can be used as the acquisition terminal of other devices.
AMR (Automatic Metering Reading), the maximum quantities of meters controlled, read and recorded by each concentrator is 400pcs. Automatic storing daily quantity of resource consumptions and time of metering reading.
Support remote or local software online upgrade to set and query meter reading scheme.
Wall mounted structure and indoor installation.
160*160 dot-matrix large LCD screen to easily query the concentrator’s running status.
Concentrator with a mass storage flash, freezing data and saving it at fixed time so that decrease the times of flash data write. All data will be saved automatically exclusive of data on a real-time basis after power off and the preservation time exceed 10 years.
Daily timing error ≤±0.5s/d, capable of master station remote time synchronization for concentrator and concentrator radio timing as well as assigned time synchronization for water meter devices.
The concentrator is capable of self-detection on a real-time basis, record and alarm of fault and abnormal events timely and report to master station and display. Record some important data at the site when all the abnormal occurrence for the purpose of analysis and deal with it.
