FMS star networking technology is the equipment monitoring system (Facilities Monitoring System) technology developed by Yibaite based on LoRa spread spectrum technology. E53-470FMS22S and E53-GW (470FMS22R) are a new generation of FMS star networking transmission modules and gateways, which have strong anti-interference capabilities, making wireless communication more stable and reliable in industrial applications, supporting ultra-large network capacity, and the gateway can access thousands of nodes at most, which is suitable for large-scale IoT application scenarios such as smart home, smart building, security system, photovoltaic, logistics, etc.
FMS star network topology
The star network of Yibaite FMS is composed of gateways and nodes, which is simple to build and easy to use. At the same time, the equipment monitoring system supports ultra-large network capacity, and the gateway can access up to 1200 nodes, which is suitable for large-scale IoT product applications.
Features:
(1) High anti-interference
The FMS star network adopts advanced LoRa modulation mode, which has the advantages of long distance and anti-interference, which greatly improves the coverage of the entire network.
(2) Ad hoc network
The gateway connects multiple node modules to achieve a star network topology, and only needs to add a 64-bit EUI node to the gateway to network, and the node automatically joins the network after powering on.
(3) Customize the dynamic allocation of network channels
The FMS system operates on multiple channels, monitors the environmental signal interference in real time, dynamically replaces the communication channel, avoids the overlap of the communication channel with the DTV (digital television) channel, and ensures the stability of the communication signal.
(4) The configuration is simple and easy to use
The E53 series can quickly realize parameter configuration through host computer or AT commands, simplify the complex, greatly simplify the complex development process of wireless products, and truly achieve simple and easy configuration, so that your products can be quickly put into the market.
(5) Network self-healing
The faulty network node module automatically joins the network after it is restored to normal operation.
(6) Encrypted transmission
AEX128 encryption algorithm is used during data transmission to ensure data security.
(7) Relay networking
The FMS network can expand the communication range by joining the slave gateway, so as to realize the trunk networking application. The gateway can be configured as a master gateway and a slave gateway, the master gateway is the core device of the network, and only one master gateway is allowed to exist in a device monitoring system network. The slave gateway interacts with the master gateway via the RS485 bus.
(8) Long communication distance
In a clear and open environment, the antenna gain is 3.5dBi, the antenna height is 2.5 meters, and the air rate is 5.4Kpbs, and the measured communication distance can reach 3Km.
Application scenarios of FMS star networks
(1) Photovoltaic power station application
In the application of photovoltaic power station, we can access the FMS network node module at the photovoltaic panel data collector, and the FMS gateway equipment can be added to the control center of the photovoltaic power station, and the node is used to collect and report the data information of the photovoltaic panel voltage, current, inverter status, temperature and humidity, irradiation, etc., and the FMS gateway receives the data reported by the node, and the photovoltaic power station control center summarizes and sorts out the status information of the photovoltaic panel, which is convenient for users to understand the photovoltaic panel power generation data and fault information in real time.
(2) Smart building applications
In the application of smart buildings, we can access the FMS network node module in the smoke sensor, temperature sensor, humidity sensor, flow sensor, and liquid level sensor, and the building control center joins the FMS gateway device, which is used to collect and report the data information of the sensor temperature, humidity, flow, smoke, etc., and the FMS gateway receives the data reported by the node, and the building control center summarizes and sorts out the information of each sensor, so that users can understand the data and alarm information of each area in real time.
In addition, it can also be widely used in scenarios such as smart agricultural greenhouses, smoke sensors and smart security.
