low cost solution!Zigbee DTU Modem for street lighting system

  1. Overview

KB3072 ZTU (Zigbee Data Terminal Unit) is enhanced Zigbee module that using high-reliability 8051 CPU core and IEEE 802.15.4 compatible wireless transceiver. Compared with similar products, it transmission distance farther, anti-jamming capability stronger and more flexible networking.

2. Product Features

•  Standard industrial products, EMC anti-jamming design, strong adaptiveness.

•  Independent research and development, the use of the classic 8051 kernel, mature, stable.

•  Embedded Watchdog chip, provide multiple Reset mechanism, can be controlled by software, achieve  

   industrial security  mechanism perfectly.

•  Work frequency 2.4GHz, transmit stable and reliable.

•  Advanced and strict data communication protocol, with the function of correction and encryption. Never lose

   package when data transmission, can achieve pictures over than 100K and Flash animation files  

   transmission, no Mosaic happened.

•  Powerful, supporting three node types: Coodinator, the Router and terminal.

•  Support three transmission modes: broadcast, master-slave, point-to-point;

•  Support variety of Auto networking: point-to-point, multipoint-to-point, point-to-multipoint, multipoint-to-

   multipoint; combined with our other product, you can set up a large cross-regional system network;

•  Plug and play function: After parameters configured and electricity turned on, the ad-hoc network is built.

   communication between control centre and devices is successfully realized through docking serial port;

•  Low power consumption: just two AA batteries can be driven;

•  Remote modify ZTU parameters: Support remote modify the parameters, after the product install, if you

   need to adjust the parameters, simply use software control terminal remote configuration the parameters;

•  Support the serial port baud rate: 1200 bps to 115200 bps, support 7, 8 data bits, one stop bit, odd parity,even parity, no parity;

•  Working temperature range: -40°C-80°C, communication is not effected at -40°C.

3. Basic Function

•  Embedded Z-Stack protocol stack;

•  Powerful, supporting three node types: Coodinator, the Router and terminal.

•  Support three transmission modes: broadcast, master-slave, point-to-point;

•  Support variety of Auto networking: point-to-multipoint, multipoint-to-point, , multipoint-to-multipoint;

   combined with our other product, you can set up a large cross-regional system network;

•  Remote modify ZTU parameters: Support remote modify the parameters, after the product install, if you

   need to adjust the parameters, simply use software control terminal remote configuration the parameters;

•  Support the serial port baud rate: 1200 bps to 115200 bps, support 7, 8 data bits, one stop bit, odd parity,

   even parity, no parity.

4. Product Application 

Based on the Zigbee network of data transmission is stable, reliable and data relay, KB3072 ZTU combined with KB3030, has been widely used in the field of unattended, remote equipment monitoring, remote data acquisition, remote meter reading and remote scheduling. 

KB3072 ZTU is widely used in electric power automatic system, remote meter reading, industry monitoring, traffic management, atmosphere, pro-environment, pipe network monitoring, finance, securities departments and so on.

4.2 KB3072 Work with Other Device

Due to Zigbee transmission as a short distance data transmission, if user's terminal equipment is scattered, how to utilize KB3072 organize a large SCADA across the region? Here we simply introduce another item KB3030, it can transmit COM data to a remote server of internet by using cellular network, based on this advantage, if connect the Zigbee Coodinator COM port to KB3030, then the internet data of Zigbee can be transmitted to internet, meanwhile, internet data can be downloaded to Zigbee network via network package. This mutual utilization of internet, realized transmission across the region, and realized the real intelligent internet of things. Topological graph is showing as below:
