Problems solved by technology

[0005] Due to the different collection objects of the connected information collectors, these node modules are usually set in different locations on site, for example, three node modules are in workshop A, three node modules are in workshop B, and some node modules are outdoors. The communication environment between the node modules will be different. In addition, whether it is in the workshop or outdoors, the environment at different times is also changing, and these differences and changes will affect the wireless communication between the node modules.
[0006] However, each node module has fixed the transmission power of the device during each communication when it leaves the factory or is installed. When the transmission power value is high and the communication environment is good, the power consumption of the node module will be large, resulting in waste of resources. ; and when the transmission power value is low and the communication environment is poor, data loss or packet loss will occur, and reliable communication cannot be guaranteed

Embodiment 1

[0031] figure 1 It is a schematic structural diagram of the Internet of Things communication system in the first embodiment of the present invention.

[0032] like figure 1 As shown, the IoT communication system 1000 includes a greenhouse 100 , an IoT communication subsystem 200 , and a user terminal 300 .

[0033] In the first embodiment, the entire greenhouse 100 is used for agricultural production. In order to make the crops or plants in the space formed by the greenhouse 100 grow well, a carbon dioxide sensor 110 , a humidity sensor 120 , a light sensor 130 , an air quality sensor 140 , a temperature sensor 150 , a carbon monoxide sensor 160 , and an irrigation collection control system are installed in the greenhouse 100 . The valve 170 and the ethylene sensor 180, these eight sensors are used as information collection and control devices, used for real-time collection of carbon dioxide concentration information, humidity information, light information, air quality info...

Embodiment 2

[0095] In the second embodiment, the same symbols are given to the same structures as those in the first embodiment, and the same descriptions are omitted.

[0096] Figure 4 It is a schematic structural diagram of the Internet of Things communication system in the second embodiment of the present invention.

[0097] like Figure 4 As shown, the IoT communication system 1000' includes a greenhouse 100, an IoT communication subsystem 200', and a user terminal 300.

[0098] The IoT communication subsystem 200' includes eight communication nodes 210', a gateway 220, and a cloud processing terminal 230 communicatively connected.

[0099] In order to facilitate the distinction, the eight communication nodes 210' are sequentially associated with the carbon dioxide sensor 110, the humidity sensor 120, the light sensor 130, the air quality sensor 140, the temperature sensor 150, the carbon monoxide sensor 160, the irrigation collection control valve 170 and the ethylene sensor 180. ...

Abstract

The invention provides a communication node capable of automatically adjusting transmission power according to communication quality, and a communication system of internet of things, including the communication node. The communication node is characterized by comprising a storage unit, a communication quality acquisition unit for acquiring real communication quality value between the communication node and a transmission end communication node, a judgment generation unit for judging whether the real communication quality value is in a standard quality range, a calculation unit for calculating a power adjustment value if the real communication quality value is not in a standard quality range, a communication unit for transmitting the power adjustment value to the transmission end communication node, receiving information after the transmission power is adjusted by the transmission end communication node, and also receiving the power adjustment value transmitted by a receiving end communication node, and a power adjustment unit for performing corresponding adjustment on the transmission power of the communication unit according to the received power adjustment value.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a communication node that can automatically adjust the transmission power according to the communication quality and an Internet of Things communication system including the communication node. Background technique [0002] As an important part of the new generation of information technology and an important product of the information age, the Internet of Things has been used in smart homes, factory intelligent monitoring and other fields, providing great opportunities for people to remotely monitor, manage and control various smart devices. convenience. [0003] The Internet of Things mainly includes two parts: node modules and gateway devices. In the Internet of Things, there are usually multiple node modules, and these node modules are respectively connected with the information collectors of each smart device, and can receive the operation data information s...
