The data application server module is to third-party application platform propelling data and the subscription that gives out information, wherein institute Stating LoRa server includes LoRa network management server module and data application server module.
Specifically, system supports that upper level applications receive data in a manner of http post or MQTT and notice disappears Breath.LoRa network management server module is also known as Network Server, is responsible for management LoRa terminal node and LoRa net The software module of pass.Such as Fig. 3, in order to simplify user installation and use, LoRa ad hoc network is by LoRa network management server module It is integrated in a physical gateway equipment, operates on the high-performance embedded mainboard of Atom and (also run data on the mainboard to answer With server module, the two software modules can also be deployed to cloud).
NS is mainly responsible for:
The connectivity management of 1.LoRa terminal node, authentication management, grouping management (supporting multicast and broadcast application) etc.；
The realization of 2.LoRaWAN agreement；
3. the integrity check that terminal user applies data；
4. the forwarding that terminal user applies data；
The configuration of 5.LoRa gateway.
The software module provides a user the graphical configuration interface UI, and user is facilitated to carry out terminal and gateway management.
It is specific how the management of being attached property, authentication management, grouping management, integrity check, gateway configuration, can use Whether general method carries out in the communications field, for example, authenticated by password comparison, according to authenticating by deciding whether Allow terminal node to be attached, management is grouped to terminal node by the position or application characteristic of terminal node, is passed through The CRC check for sending message carries out integrity check etc., the present embodiment not reinflated discussion to this.
Data application server module becomes Application Server, is responsible for the encryption and decryption using data, and to the Tripartite's application platform provides various data push services and message subscribing issuing service.User can pass through standard HTTP POST User data is obtained with MQTT network protocol, sends user's control signaling.
Such as Fig. 3, in order to simplify user installation and use, LoRa ad hoc network will be integrated in one using data server module In physical gateway equipment, operating on the high-performance embedded veneer host of Atom (can also be deployed to cloud).Ethernet can be passed through Or the connection of 4G LTE network and third-party platform communicate.
When application side subscribes to message, system is given out information with following subject pattern:
application/[applicationID]/node/[devEUI]/rx
Example: following order indicates to subscribe to the end that devEUI is 373138357837820e in the application that ID is 3 The uplink message at end
