Embodiment 1

[0022] Such as figure 1 As shown, the wireless sensory control network application system in the present invention consists of two major elements, namely the wireless sensory control node 101 and the wireless coordinator 102 . In the white monitoring area 103 in the figure, a large number of wireless sensing and control nodes are randomly distributed and deployed to form a network through self-organization. Each node can collect real-time data of its coverage area and transmit it hop by hop along other wireless sensing control nodes. During the transmission process, the monitoring data will be processed by multiple nodes and routed to the wireless coordinator after multiple hops . Node A in the figure realizes data forwarding through a multi-hop route of A-B-C wireless coordinator, and the situation of other sensing and control nodes can be deduced by analogy. The wireless coordinator is a special gateway node, which has relatively strong processing, storage and communicati...

Embodiment 2

[0024] figure 2 It is a schematic diagram of a typical wireless sensor control node system model, which describes the six major components of the wireless sensor control node, namely:

[0025] 1. (Central) processing unit 201

[0026] The (central) processing unit is responsible for controlling the operation of the entire wireless sensor control node, and provides simple encryption calculation processing and necessary buffer before sending for the data collected locally and the data forwarded by other nodes.

[0027] 2. Storage unit 202

[0028] The storage unit can record the real-time data collected by the sensing unit. Its function is to back up and store the data locally when the network connection is limited, and send the data to the original target device when the connection is restored.

[0029] 3. Radio frequency unit 203

[0030] The wireless radio frequency unit is mainly responsible for wireless communication with other wireless control network devices, including...

Embodiment 3

[0038] Such as image 3 As shown, in order to improve the use efficiency of power supply energy and maximize the working cycle of the wireless sensor control network, the working modes of the wireless sensor control nodes in the present invention are divided into four types, namely:

[0039] 1. Idle mode 301

[0040] Idle mode is set as the initial default working mode of this wireless sensor control node. When the node works in idle mode, it will always monitor the usage of the channel to check whether there is data sent to itself.

[0041] 2. Receive mode 302

[0042] When the wireless sensor control node in idle mode detects that there is data sent to the local, it will automatically switch the working mode to the receiving mode, and start receiving, processing and storing the corresponding data.

[0043] 3. Send mode 303

[0044] When the wireless sensing control node in the receiving mode confirms that the calculation and processing of the received data is completed, it...

Abstract

The invention discloses a wireless sensing control network system based on the Internet of Things. The wireless sensing control network system based on the Internet of Things is mainly composed of one or more wireless sensing control nodes and one or more novel wireless coordinators. According to the wireless sensing control network system based on the Internet of Things, the novel wireless coordinators are accessed to the Internet, an end user can sense and reversely control the surrounding environment by means of the wireless sensing control nodes in a wireless sensing network system, the user can remotely monitor the surrounding environment, such as the temperature, the humidity and the air pressure, of an inductor through the inductor integrated by the sensing nodes, and on the aspect of reverse control, manual remote control can be provided for the user by the wireless sensing control nodes or an automatic control scheme can be made according to the user. The wireless sensing control network system based on the Internet of Things has the advantages that due to the fact that the wireless sensing nodes form an integral micro embedded system on the aspect of the hardware architecture, the power consumption is low, the mobility is high, and the cost is low.

Description

technical field [0001] The invention relates to a control network system, in particular to a wireless sensor control network system based on the Internet of Things composed of a sensor controller, a wireless node and a wireless coordinator. Background technique [0002] The Internet of Things is an important part of the new generation of information technology. Its English name is "The Internet of things". Therefore, as the name suggests, "the Internet of Things is the Internet of things connected to each other". This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; exchange and communication. Therefore, the definition of the Internet of Things is to connect any item with the Internet through radio frequency identification RFID, infrared sensors, global positioning systems, laser scanners and other information sensing devices according to the agreed agreement,...
