Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0053] According to an embodiment of the present invention, a sensor network for monitoring the environment of cultural relics exhibition is provided.

[0054] Compared with the general indoor environment monitoring, the monitoring of cultural relics exhibition environment has its particularity. First of all, the cultural relics exhibition environment is relatively harsh due to the shielding of visitors, electromagnetic noise from air-conditioning equipment and security equipment, etc., and the packet loss rate is high and fluctuating. Secondly, due to the needs of security and maintaining temperature and humidity, the exhibition Most of the exhibited cultural relics are placed in airtight glass cabinets, which require the nodes of the sensor network to have a longer survival time, so that during the entire exhibition period, there is no need ...

Abstract

The invention provides a sensor network for environmental monitoring. The sensor network comprises one or more sensing nodes, a plurality of routing nodes and a center node, wherein the sensing node is used for acquiring sensing data and transmitting a sensing data packet to the plurality of routing nodes; the routing node is used for receiving the sensing data packet, setting delayed forwarding time for the received sensing data packet, and forwarding the sensing data packet to a parent node of the routing node at the delayed forwarding time under the condition that the sensing data packet is not forwarded by another routing node at a current moment; the parent node is the center node or another routing node; the delayed forwarding time is randomly selected; and the center node is used for summarizing the sensing data packets. The invention also provides a corresponding data transmission method. By the sensor network and the method, the problem of over-high 'hotspot' energy consumption speed in the network is effectively solved, thereby prolonging the service life of the network. The outdegree of each sensing node is far more than 1, so data loss can be completely avoided.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things and the technical field of target monitoring, in particular, the present invention relates to a sensor network and a data transmission method for environmental monitoring. Background technique [0002] With the rapid development of microelectronics technology, computing technology, sensing technology and wireless communication technology, wireless sensor network has received more and more attention, and has shown great application value in both civilian and military fields. The wireless sensor network is composed of a large number of cheap micro-sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network system through wireless communication. information and send it to observers. Wireless sensor networks have the characteristics of convenient deployment, self-organizing network, low cost, close application integration, reliability and scalabi...
