Problems solved by technology

[0012] In the application, the device nodes of the network are composed of a large number of sensors, and it is impractical to set up a large number of base stations in it to form a direct wireless coverage. These sensors only need to send a small amount of data intermittently, for example, Zigbee or IEEE802.15.4 Standard etc. network structure, sending 50-100 bytes every 5 minutes (up to once a day), is inefficient and requires a pre-installation phase process or on-site configuration
The system installation process can be challenging for electricians and power meter field installers

Embodiment Construction

[0054] The network of sensor devices of the present invention is a recursive grid tree network communicating on a wireless narrow frequency band. The sensor devices have a very simple radio which is arranged between the sensor devices to form a link. Centralized command and control of all processes regarding the network of sensor devices comes from the cloud server, except the alarm function originates from the sensor devices in the mesh tree network.

[0055] Network configuration is accomplished by passing information from a cloud-based central provisioning server. A central provisioning server in relation to the cloud refers to a network of remote servers hosted on the Internet (Internet) for storing, managing, and processing data, rather than local servers or personal computers. Linking within the network is accomplished by linking sensor devices. Each sensor device node maintains basic device identification information, and the basic device identification information is...

Abstract

A narrow-band wireless data network includes a central provisioning server that is configured for providing command and control data to the network, to retain the mesh-tree structure of the network, and to manage and retain all sensor data and new connection requests. A gateway device is connected to the central provisioning server for communicating with the network through a first and a second radio receiver / transmitter that is configured to send and receive data on at least one frequency channel. Multiple device nodes that control and communicate with associated sensor devices for collectingsensor data. The device nodes interpret and execute commands transmitted from the gateway device or other device nodes on the network addressed to individual device nodes. The commands are executed with no acknowledgment.

Description

technical field [0001] The present invention relates to a network architecture, in particular to configuring a recursive grid tree network, and even to a communication protocol capable of automatically configuring a recursive grid tree network. Background technique [0002] A sensor network is an interconnected network of elements that sense or measure events occurring in the physical world. Sensors provided by these components include electric and magnetic field sensors, frequency modulation sensors, optical sensors, photoelectric sensors, infrared sensors, radar, laser, position / navigation sensors, seismic and pressure wave sensors, environmental parameter sensors (e.g. wind, humidity, heat), and national security-oriented biochemical sensors. The detected phenomena are digitized and retained in electronic storage, then transmitted on command via a wireless network to a central processing system. [0003] The sensor elements are low-cost, low-power, unlimited multi-funct...
