Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] Such as figure 1 As shown, a LoRa core network system of the present invention includes: a gateway, a data distribution server, a network management server, an application management server and a database server.

[0061] (1) The gateway regularly reads the message received by the gateway radio frequency module from the wireless interface, encapsulates the read message and sends it to the data distribution server, and performs time synchronization with the data distribution server; The data distribution server pulls the message that the data distribution server needs to deliver, parses the message, and then sends it to the sensor with the help of the gateway radio frequency module.

[0062] (2) After the data distribution server receives the message from the gateway, it receives, verifies, parses and encapsulates the message from the gateway,...

Abstract

The invention relates to a LoRa core network system and a realization method. According to functions of designed gateway, network management server, application management server, data distribution server and database server, a task of operating and managing a LoRa network can be finished. The designed application management server based on Nginx, TCP connection is taken over by Nginx, and parameters of request service are borne by a body in an HTTP message. A service request module is docked with an Nginx module. The realization complexity resulting from managing the TCP connection by an Epoll model is avoided, the system expansibility is improved, and the maintainability is relatively high. A request preprocessing mode accesses the rapid processing and blacklist filtering LoRa network based on a UDP, requests are rapidly transmitted to the data distribution server through the UDP, through blacklist filtering, illegal requests are prevented from entering the application management server through the data distribution server, and the system security and reliability are ensured.

Description

technical field [0001] The invention relates to a LoRa core network system and an implementation method, and belongs to the technical fields of the Internet of Things and low-power wide-area wireless networks. Background technique [0002] The concept of the Internet of Things has been proposed for almost 15 years, and a large number of products have emerged. Summarizing the main requirements, we can find the main characteristics of the Internet of Things products: data collection, small amount of control, small amount of single data, and low collection frequency , The real-time requirements are not strong, and some applications have reliability requirements; the number of collection nodes is large, it may be very dense, and it may be very scattered; the nodes have low computing and storage capabilities, long-term deployment, and no mains conditions. These requirements mainly focus on low speed, large capacity, wide coverage, low power consumption, and low cost. [0003] In...
