Internet of Things gateway for perceiving wild environment and data transmission method thereof

Abstract

The invention discloses an Internet of Things gateway for perceiving wild environment and a data transmission method thereof. The gateway comprises a SinkNode module, a core advanced RISC machines (ARM) control module, a general packet radio service (GPRS) module, a third generation telecommunication (3G) module and a power supply module, the SinkNode module, the GPRS module, the 3G module are respectively connected with the core ARM control module, and the power supply module is connected with other modules. The method includes that node acquisition data of a monitored region is sent to the SinkNode module, the SinkNode module sends the data to the core ARM control module, the data is classified and sent to the GPRS module and the 3G module by the core ARM control module, the GPRS module sends sensing data to a remote server, and the 3G module sends image data to the remote server. The gateway uploads the perception data of the wild environment to a data base of the remote server through the GPRS network and 3G network on the Internet of Things gateway, so that a monitoring center can real-timely receive the data and can further process the data in the data base of the remote server, and the data remote supervision by the monitoring center is achieved.

Description

technical field [0001] The invention belongs to the field of wireless sensor networks, and in particular relates to an Internet of Things gateway for sensing a field environment and a data transmission method thereof. The gateway is used for long-term supervision of node data in the field environment, remote real-time data transmission, and reliable data monitoring . It can be mainly used in field environmental scientific research, exploration, investigation, animal protection and other fields. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) consists of large-scale deployment of micro-sensor nodes, these simple nodes have information perception capabilities, real-time communication capabilities and simple computing capabilities. Each micro-node distributed in the sensor network cooperates to monitor, sense and collect environmental data in real time, realize the communication between wireless sensor network nodes through the ZigBee proto...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned typical gateways have the following deficiencies: serial PC gateway MIB510, USB PC gateway MIB520, and Ethernet PC gateway MIB600 are all gateways connected to PCs, which can only be used after they are connected to PCs. There is no PC in the environment, so this kind of gateway cannot be used; the NB100 embedded wireless sensor network gateway has a great improvement over the above gateway, but it does not solve or propose a complete energy supply problem in the wild environment, and in It is almost impossible to find Ethernet access points in the wild environment, and there is no good solution to the access problem of Ethernet

First of all, simply using GPRS to transmit data can only transmit simple sensing data, and it is impossible to realize the image transmission of the field environment for real-time observation of the field environment; secondly, the pure use of 3G to transmit data, although It can solve the problem of remote image transmission, but it brings 1) the 3G module cannot distinguish whether the data is image data or sensor data when the server receives the data; 2) sensor data and image data cannot be sent at the same time, This will increase the packet loss rate of data, affect the quality of data links, receive no data due to unsatisfactory 3G signal coverage, and high power consumption (frequent switching between 2 / 3G networks will increase power consumption), etc. a series of serious problems

In summary, the existing gateway technology cannot meet our requirements for IoT gateways in the wild
