This program uses the NXP JN518X series of the Daba Group Agent Zigbee 2.4 G wireless RF chip, compared to market similar products, JN5189 has higher performance, lower power, lower prices, and more complete technology development materials And the better application development technical support provided by the Daba Group. NXP as a chip manufacturer in the infiltration Zigbee field, and its JN series ZigBee chip has been welcomed by the industry. The mainstream JN5169 series has been the first choice for many large smart equipment manufacturers.
This program uses NXP's latest JN518X series chip, compared to previous generation products JN5169, whether it is performance or power consumption, with great improvement, with NXP stable Zigbee underlying protocol stack and perfect application layer architecture, let customers only A zigbee project can be quickly completed simply to apply a zigbee project, which greatly reduces the project development cycle. This program is a router with relay function based on JN5189. As a relay route, it can also be used as a wisdom lantern to add color to smart home. With the big tree clouds and mobile apps of the Dacheng Group, you can remotely control the open lights, control other smart home equipment connected to the relay route, no matter whether your smart home equipment is in your home. The corner can be completely covered, let you enjoy the opening of the door, it is the warm light.
Transmission technology problem solved in this program
With the improvement of consumption levels, more and more people have started using smart home equipment, and more and more we are familiar with the manufacturers began to enter the intelligent home area. To manage less than 2-3 per family, more than 100 - 200 smart home devices require a huge data transmission network, transfer each device to the user's mobile app for management.
Current mainstream wireless transmission technology: Zigbee, Ble, WiFi, is used in smart home field, but BLE and WIFI have more or less in smart home applications. BLE only supports point-to-point transmission, which cannot transmit so large multi-node data, only suitable for some functions, need to directly connect to the application of mobile phone, short transmission distance, can not top the extent. WiFi significantly exceeds BLE and ZIGBEE technology, which has an advantage in transmitting large traffic, but it is not suitable for data traffic, small power consumption demand, and a battery requires a year of smart devices. However, ZigBee has since its birth, low power, self-assembled network, topological extension, is its advantage. The relay route application of this program will be easily extended for a few hundred meters, covering every corner of the home, while as a wisdom lantern, controlling everything in the home by mobile phone.
Usage scenarios
This trunk routing scheme provides a relay node to some smart devices from home gateways, so that these smart devices can be successfully linked to home gateways, allowing users to stably use smart devices.
The rough application scenario is as follows: A 3-storey villa, the home gateway is typically placed in the three-layer room placed in a smart light A, because the transmission environment is affected by the wall and distance, the smart light A may be difficult Link to the home gateway. The user wants to fail the remote opening. At this point, the routing repeater of this program is placed on the second layer, allows the smart light A to the repeater, the repeater is linked to the home gateway to forward the control information, so that the user can successfully turn the light. At the same time, the lanterns on the routing relay can also be controlled by the user, so that the second layer can also be open.
