Method and system for data transmission by Internet of Things devices

Abstract

The invention relates to a method for transmitting data through an internet of things device. The method comprises the steps that current attribute data of the internet of things device is obtained, wherein the attribute data comprises attribute types and corresponding current attribute values thereof; a difference value of a current attribute value and an attribute default value of each attribute type is calculated to form an attribute difference value; on the basis of the internet of things, the attribute difference value is sent to a remote system which is in communication connection with the internet of things device, the remote system is combined with the attribute difference value and the corresponding attribute default value thereof, and the current attribute data of the internet of things device through calculation. Due to the fact that the attribute default value is configured for the internet of things device, when the attribute data is sent, the different value of the current attribute value and the attribute default value only needs to be sent, the transmission data size is greatly reduced, the network bandwidth is saved, and the communication cost is reduced.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and a system for transmitting data from an Internet of Things device. Background technique [0002] With the rapid development of the Internet of Things industry, more and more "things" are connected to the Internet through various connection technologies. Some states and attributes of these devices need to be reported regularly or irregularly. In many cases, the Internet of Things needs to monitor and manage these devices in real time. The frequency of reporting the status and attributes of the devices will be very high, and the number of messages reported each time will also be large. If each IoT device continuously sends device attributes to the remote system side at its own system time 1 to N, when the device status and attributes are complex and the reporting cycle is short, the traffic from the IoT device to the network side cannot be underestimated , and it...
