Internet of Things technology in the evolution of campus information technology is divided into several stages, we call it the pre-IoT stage, the transition stage, and the current campus IoT stage.
The traditional classroom is part of the era of central control, most of the classrooms still exist, may use RS232, RS485 and other interfaces, as well as, for example, infrared, there are some obvious shortcomings, one is wired to connect the workload of operation and maintenance is very large. The second is the requirement of equipment in the same LAN, three is not uploaded to the cloud, difficult to do statistical analysis, four is the IOT is to the classroom as a unit, detached from the classroom is very difficult to control. Some new devices, slowly has not supported this interface, so its expandability will be very poor, you may take a new device, he may not be able to control.
In recent years, some of the short-range wireless IOT solutions have gradually entered the people’s field of vision, such as Bluetooth and other short-range wireless solutions, but they have some obvious shortcomings relative to the previous, that is, it is more limited, the classroom can not let the data on the cloud to do analysis.
With the arrival of 5G technology, slowly formed 5G, NB-IoT, LoRa and other long-distance wireless interconnection programme, they have some obvious advantages, first, wireless communication does not need to go to the wiring or transform the existing environment of the line layout.
Two, local control and cloud control are combined.
Thirdly, things are connected to each other through the IoT cloud, can no longer be limited to the classroom scene, can be very convenient to carry out some scene linkage, the transformation of the existing equipment is also very simple, can be teaching information technology equipment and traditional environmental equipment, application data seamlessly through. Like this long-distance wireless IOT programme, its penetration capability is very strong. For example, a gateway, a building may only need to deploy 3-4 has been able to cover very well. 5G this piece in fact slowly formed a number of industrial alliances, we are in the unified communications specifications, and the equipment is able to interconnect.
In order to build IoT smart classrooms with other manufacturers in the future, XIVO will adopt different solutions in the use of IoT technology solutions, for example, there are some traditional central control solutions in the classroom, through our intelligent podium, the traditional serial port, infrared connection of the equipment connected together, and then the intelligent podium through the LoRa technology and the cloud connection, to achieve the traditional and the existing new technology is very well combined. together.
