WSN (Wireless Sensor Network) based cluster state monitoring system and method

Abstract

The invention relates to a WSN (Wireless Sensor Network) based cluster state monitoring system; a wireless sensor network formed by a plurality of wireless sensor nodes arranged on equipment is connected with a sink node, the sink node is connected with a data management and analysis platform, the data on all the wireless sensor nodes is directly transmitted to the sink node or is transmitted to the sink node in a hop-by-hop manner, the sink node is a sensor mode for enhancing data processing function or is gateway equipment only provided with a wireless communication interface. The invention provides the WSN based cluster state monitoring system and a method; the working state information of construction equipment can be accurately acquired by the wireless sensor network, and a fault diagnostic system constructed based on the virtual instrument technology can timely find the fault type and the fault part, and can gives an alarm at the key moment, so as to avoid inadequate maintenance and excessive maintenance of the equipment, prolong the service life of the equipment, reduce the maintenance cost of the equipment and ensure the construction safety.

Description

technical field [0001] The invention relates to the field of state monitoring of machine clusters in construction projects such as water conservancy and hydropower and transportation hubs, in particular to a WSN-based machine cluster state monitoring system and method. Background technique [0002] In recent years, water conservancy, hydropower, and transportation hub construction projects have a large amount of work, tight schedules, and strict requirements for project quality, which must be completed with highly modernized construction machinery and equipment. In a sense, construction machinery plays a decisive role in the quality of project construction. Since the construction equipment is mostly open-air operations, affected by wind, rain, sun, atmosphere, dust and erosion, the working environment is very harsh and failures are frequent; and the characteristics of construction production determine that they work on various construction sites, with large dispersion and st...

Problems solved by technology

Since the construction equipment is mostly open-air operations, affected by wind, rain, sun, atmosphere, dust and erosion, the working environment is very harsh and failures are frequent; and the characteristics of construction production determine that they work on various construction sites, with large dispersion and strong mobility , which brings great difficulties to the timely elimination of faults

However, real-time monitoring of traditional manufacturing production equipment requires laying a large number of cables or optical fibers to form a transmission network. For occasions with harsh working environments (such as rotating parts, compressors, etc.), wiring and power supply will be limited, and the cost of monitoring network construction and maintenance will be limited. very high

With the increase in the complexity and automation of mechanical equipment, traditional maintenance technologies (such as downtime inspection and planned maintenance) are difficult to meet the needs of maintenance cost and efficiency, and more reasonable and efficient equipment operation status monitoring and diagnosis technologies are needed to reduce downtime. , reduce operation and maintenance costs, and extend the service life of equipment
