Method for detecting equipment failure

Abstract

The invention discloses a method for detecting equipment failure. For the inherent advantage that the wireless sensor network nodes themselves are capable of information communication in a distributedwireless sensor network, the information between adjacent nodes is interacted, a set of distributed wireless sensors in a given area collect data, and the use of the neighbor equipment and the equipment is reasoned based on the data of perception nodes of neighbor nodes, thereby increasing the probability of detecting hidden failures, and greatly reducing the probability of major accidents. Whenthe wireless sensing nodes detect local abnormal data, the wireless abnormal data control center is used to trigger all the equipment self-checking commands. At the same time, in the normal detectionprocess of the wireless sensor network, even if not perceiving that the parameter abnormity control center randomly command and timely command all the sensing nodes to upload the data, the detection effectiveness and reliability of the wireless sensor network are improved.

Description

technical field [0001] The invention relates to a method for detecting equipment faults in an industrial process equipment chain based on a distributed wireless sensor network. Background technique [0002] As an important component of the manufacturing industry, the industrial process has the characteristics of scattered space, complex structure and high degree of automation in the equipment chain of the industrial process. Different from the discrete manufacturing industry, its products are assembled from multiple parts through discontinuous processes, and the failure of a single device will not affect the entire manufacturing process; the mechanism of industrial process changes is driven by material balance and energy balance, which affects the entire process. The smooth operation of the online industrial process equipment chain has high requirements. Once a certain equipment fails, the entire process operation will be stopped. Therefore, it is necessary to detect the op...

Problems solved by technology

At present, wireless sensor networks are used for equipment detection, and most of them use a single sensor node to sense parameters and upload them to the working mode of the data processing unit. The data processing unit makes data judgments. When the device has a hidden fault, the single sensor node senses the parameters. Normal, the probability of equipment failure cannot be reduced through failure prediction, so by the time a single sensor node perceives parameters to indicate equipment failure, a major accident has often occurred
