Embodiment Construction
[0017] In order to understand the present invention more clearly, the present invention will be further described and illustrated below in conjunction with the accompanying drawings.
[0018] figure 1 It is a structural diagram of a large-scale equipment safety monitoring wireless sensor network. Attitude detection node 1 and acousto-optic detection node 2 are deployed at multiple points on large-scale equipment. Attitude detection node 1 collects acceleration, inclination, and speed parameters, and acousto-optic detection node 2 collects sound and light. Attitude detection node 1 and acousto-optic detection node 2 are equipped with long-distance radio frequency modules. The network adopts a two-layer cluster structure and uses multi-channel to resist interference. The cluster head accumulates the data in the cluster and forwards the data to the sink node in the form of multi-hop. The sink node is equipped with a highly sensitive antenna to receive long-distance data. The sin...

The invention discloses a safety monitoring wireless sensor network for large equipment, and the network provided by the invention is suitable for working state detection and operation safety monitoring of various large manufacture equipment. The monitoring network comprises an attitude detection node, an acousto-optical detection node, a cluster node and the like, wherein the attitude detection node collects gradient, displacement and acceleration parameters; the acousto-optical detection node collects sound and light of a working area; and a plurality of detection nodes configured on the large equipment send collected data to a monitor computer through the cluster node for fusing, so that attitude, abnormal acousto-optical information and other information of the equipment are acquired. The safety monitoring wireless sensor network is of a multi-channel clustering network structure, and adaptively selects a channel according to the field environment and link quality to reinforce the communication interference resistance, wherein the communication distance among the nodes can be 1,000m, and the average transmission delay of the cluster node is less than or equal to 10ms. By utilizing a plurality of cheap attitude and acousto-optical detection nodes, the safety monitoring wireless sensor network can be used for realizing the safety monitoring on the large equipment.
Description
technical field [0001] The invention relates to the fields of production process state detection and operation safety, and provides a wireless sensor network system for safety monitoring of large-scale equipment. Background technique [0002] If various large-scale equipment fails during operation, it may cause huge loss of life and property, so the safety monitoring of large-scale equipment is very important. Traditional industrial monitoring communication networks are basically based on wired networks, which require wiring during installation. In addition, traditional wired monitoring networks are also inconvenient in mobile workplaces; on the other hand, the cost of wired monitoring networks Also relatively high. Wireless sensor networks do not require on-site wiring. They have the characteristics of self-organization, low cost, low power consumption, and good mobility. They can greatly reduce construction costs. Using wireless sensor networks to monitor large-scale equi...
