Modulation model:GFSK
Wireless transfer rate:9600bps,8E1
Wireless working way:Ad-Hoc
Amr water meter data collector, water meter wireless router collector, water meter router collector
Description:
The wireless data collector for AMR water meter applies one kind short distance, low power, high speed transmission,
high reliability two-way wireless communication technology. It is
one special form of mobile Ad-Hoc.
Ad-Hoc is new type wireless network frame; it is different as any
traditional wire & wireless network. Wireless Ad Hoc is
regarded as the combination of WLAN & Ad-Hoc; it involves both
advantages and has special Excellency.
Product characteristic
1.Network independence
Wireless Ad-Hoc network can quickly establish one mobile
communication network at any time and in any place without support
from hardware & basic network facility. It has strong
independence.
2. Dynamical changing network topology
In Ad-Hoc network, host computer at the same time is router, so
movement can make network topology structure change continuously.
It can extend collector & concentrator according so to meet
users’ increasing, and then can finish AMR system. No needs
additional network wiring & re-construction etc.
3.Network distributed characteristic
In Ad-Hoc network there is no centre control point, host computer
interconnects by distributed protocol, once one point or some
points of the network happen fault, other points still can work
properly. The network can appoint one gateway, through the gateway
it can interconnect with other wireless network or wired network,
so it can realize flexible and big scale networking.
3.Good robustness
All hardware & software designed for industrial field
environment, all wireless intelligent water meters inside the
system can be read by short distance wireless channel, one-time
successful reading rate is more than 99.5%
3.Anti-interference & safety
Since applied high frequency adaptive mechanism, it reduces
affection of data communication caused by nearby wireless signal
crosstalk & other wireless interference source. The air
wireless data of short distance wireless Ad-Hoc network uses
special data encryption, dynamic frequency hopping and adaptive
frequency hopping, it has high security.
4.High speed data transmission
Single data package transfers big valid data. In any single
communication period, end to end whole course data communication,
it uses 2-grade 32 bits CRC calibration, which makes total residual
error rate to be 0.
Applications:
It is bi-directional communication link between wireless concentrator and wireless electronic AMR water meter inside the complete AMR network system, and it is core part of the underlying network.
