The embedded memory standard specification of the products such as tablet personal computer.The MCU is provided with light-duty server, has part server work(
Can, the node data being attached thereto can be gathered and parse, acquisition parses data and corresponding messaging parameter and stored
In the EMMC memories being attached thereto.Also include the power supply module and power management chip being connected with MCU, be gateway of the present invention
Power supply is provided.
In addition, in order to realize the control function of the intelligent terminals such as mobile phone, the multifunctional intellectual LoRa gateways of this example also include
Ethernet interface and wireless communication module, the Ethernet interface and wireless communication module are connected with MCU.The radio communication mold
Block can be 4G/5G communication modules, bluetooth communication, the wait of WIFI communication modules.
As shown in Fig. 2 the gateway of this example has following function：
1st, data processing function
The MCU of this example is provided with light-duty server, and MCU processors can easily handle light-duty server programs, so as to using gently
Type server programs, the data come up to node collection parse, and acquisition parses data and corresponding messaging parameter
Index, light-duty server in EMMC memories, and provide data classified and stored to the API query interfaces of various data, intelligence
The application program of mobile phone can obtain current reception data and communications parameter by api interface.
2nd, manual configuration function
The multifunctional intellectual LoRa gateways of this example support that, by controlling terminal manual configuration, the parameter of the manual configuration includes opening
