With the continuous development of sensors and communication technologies, the Internet of Things industry is in the ascendant, and business links involve data collection, communication connections, data storage, data visualization, insights, and action decisions . However, during the implementation process, the fragmented device-side communication connection problems often hinder the project implementation process.
Today, this article summarizes the cloud connection solutions for different device scenarios for your reference.
Resource-rich equipment
With the development of high-performance hardware, many smart devices have complete Linux, Android, Arduino and other operating systems. At the operating system level, the differences between different communication modules are resolved. The hardware-side applications only need to integrate the IoT SDK of the cloud platform , or integrate The open source MQTT SDK can establish a long connection communication link with the cloud.
Resource-constrained equipment
In the Internet of Things scenario, a large proportion of devices are resource-constrained, running ROTS systems, or even without operating systems, using MCU + communication modules to realize remote collection of device data.
There are many suppliers of cellular module (NB-IoT/2G/3G/4G) in the market, such as Quectel, SIMCom, Hezhou, Youfang Technology, Guanghetong, Sunsea Intelligent, Gosuncn, etc. The AT commands of different companies are also different, which brings great difficulty to the development of device-side applications.
According to the different degree of module integration, several scenarios are subdivided:
Local communication equipment
In the Internet of Things scenario, there are a large number of devices that only have local local communication capabilities, such as Bluetooth devices, ZigBee devices, LoRa devices, and Modbus devices, without Internet access protocol stack support. In this case, DTU/gateway devices , proxy The device converts the local protocol into the MQTT protocol to realize data collection and uploading to the cloud.
The local system goes to the cloud as a whole
In scenarios such as industrial and commercial complexes, there is often a mature system locally that realizes the centralized collection of equipment data. Due to the unified management of the group's business, it is necessary to collect data from various places on the cloud.
Faced with this kind of scenario, it is possible to use its own system integration and generalization SDK through the HTTP/2 protocol to efficiently realize the rapid upload of massive data to the cloud without modifying the equipment.
