Background

A Base Station (BS), i.e., a public mobile communication Base Station, is a form of a radio Station, which refers to a radio transceiver Station for information transmission with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area.

Long Range radio (long Range radio) is a low power consumption local area network wireless standard created by semtech corporation, low power consumption is generally difficult to cover long distance, and long distance is generally high in power consumption. The LORA is characterized in that the LORA has a longer propagation distance than other wireless modes under the same power consumption condition, realizes the unification of low power consumption and long distance, and has an expanded distance by 3-5 times compared with the traditional wireless radio frequency communication under the same power consumption condition. LoRa and LoRaWan are easily confused. LoRa is a subset of LoRaWan, which includes only the physical layer definition, and also the link layer.

The technical scheme of the existing LORA base station is mainly developed based on a 4G module of a ground network, the base station is downward compatible with 2/3G and the like (4G full network communication), part of products simultaneously support Ethernet connection, the LORA node uploads data to the LORA base station in a wireless mode, the base station transmits the data to a server through a public network (4G network), the server transmits the data to a cloud platform, and a user can remotely monitor the real-time state of downstream equipment connected with the downstream LORA node through the cloud platform. The existing LORA base station scheme has the following disadvantages: first, the communication method mainly uses the ground network technology, and is limited by the coverage of the ground base station. Because the base station has high construction cost and needs power supply and maintenance, the coverage range of the ground network base station is actually very limited at present, most of the coverage areas cover cities and towns, and the base station covers vast places without ground network signal coverage such as mountains, outdoors, seas and the like. Second, there are data security issues.

Example (b): a heaven-earth integrated dual-mode LORA base station mainly comprises five parts:

the first is a core data processing unit of a base station: the memory comprises a main control chip MT7620A and a DDR local storage unit. The main control chip adopts a forwarding technology MT7620A, and integrates an 802.11n Wi-Fi transceiver, a 580MHz central processing unit, a high-speed Ethernet port physical layer, a HNAT, a memory accelerator, a USB2.0 and a plurality of slow input/output (I/O). The DDR is purple DDR 2-SCN 18T1G160 AF.

Second, the LORA radio frequency front end: the baseband chip adopts SX1301 (or SX1308) of a Semtech original factory, and the SX1301 digital baseband chip is a huge digital signal processing engine and is specially designed for providing breakthrough gateway capability in the global ISM frequency band. The radio frequency driver selects 2 SX1255/SX1257 matched baseband chips, and the SX1255/SX1257 can be flexibly matched (the frequency bands of the two drivers are different). Support standard LoRaWAN protocol: ClassA, ClassB, ClassC. Defaulting to 8 uplink channels and 1 downlink channel (the number of uplink channels supports extension to satisfy hanging more downstream LORA nodes).

And thirdly, an uplink channel part of the base station. The uplink channel part is subdivided into a satellite communication unit and a ground network communication unit. Considering the practical problems of the number of nodes supported by LORA networking, networking real-time performance, concurrency and the like, the OGI satellite communication module is selected by the satellite communication unit in priority, and the module is directly connected with the main control chip through a UART port. The ground communication unit selects a 4G module M8321 of the transfer Internet of things. Meanwhile, the main control chip MT7620A supports ethernet output and WIFI.

And fourthly, a satellite positioning unit. The unit adopts an Ublox MAX-M8 GNSS module, the module is miniaturized and has low power consumption, and can simultaneously receive up to three GNSS systems: GPS/Galileo, Beidou, or GLONASS. The MAX-M8 module can identify multiple constellations simultaneously, providing excellent positioning accuracy in urban canyons or weak signals. These modules provide high performance even at low power consumption levels. For better and faster positioning improvement, the MAX-M8 module supports QZSS, IMES enhancements along with WAAS, EGNOS, MSAS, GAGAN. The base station can report the local GPS information to the server and the platform, so that the base station management and the global deployment are facilitated.

And fifthly, an external interface unit. The external interface unit comprises a WIFI/USB interface for connecting the handset and upgrading the firmware of the base station, and two WIFI/USB interfaces are reserved in consideration of different installation scenes. The external interface unit also comprises an Ethernet port for supporting the reporting of Ethernet data.

The main communication flow of the base station is divided into two flows, one is from a downstream LORA node of the base station to the LORA base station; one is the LORA base station to the server or platform (core of the present invention). After the data reported by the downstream LORA node is completely transmitted to the base station, the base station encrypts and stores local hardware, and uploads the encrypted data (including GPS data of the base station) to a server or a cloud platform through a satellite network or a ground network. Considering that the cost of the satellite network is relatively expensive, the ground network is preferentially adopted for data reporting in the default state of the system, and the system is automatically switched to the satellite communication mode when the ground network communication signals cannot be detected or the ground network signals are poor.
