Problems solved by technology

However, since the current signals collected by each data acquisition terminal are directly transmitted to the monitoring host, due to the large amount of data, congestion may occur, resulting in data transmission failure, which further reduces the reliability of the current monitoring system

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] According to the current monitoring method of enterprise electrical equipment based on distributed network in this embodiment, the current system based on distributed network used is such as figure 1 As shown, it specifically includes: several sub-nodes, a main node and a main server, and the sub-nodes are connected to electrical equipment. Sub-nodes include AC signal acquisition module, signal processing module and ZigBee wireless transmission module. The total node includes data buffering and processing module, ZigBee wireless receiving module and EtherCAT communication module. The AC signal acquisition module in this embodiment is a Hall-type current sensor, which can directly collect the AC current of the electrical equipment and output a DC signal.

[0027] The working process of the current monitoring method of the enterprise ele...

Abstract

The invention discloses a current monitoring method for enterprise electric equipment based on a distributed type network. Child nodes in the current monitoring method collect currents of the corresponding electric equipment, so that alternating current signals are obtained, and AC-DC conversion is performed on the alternating current signals to obtain direct current signals. A ZigBee wireless transmission technology is adopted for transmitting the direct current signals to a parent node, after the parent node performs buffering and screening on the direct current signals, and the direct current signals are uploaded to a parent server by the adoption of a wire transmission technology and used for monitoring the currents of the electric equipment. In the current monitoring method, due to the facts that the parent node performs the data buffering and screening on the current signals, collected by the child nodes, of the electric equipment, and the wire transmission technology is adopted for transmitting the current signals to the parent node, the probability of data transmission failure caused by transmission congestion is reduced, through the data screening, the incorrect current signals are removed, so that the data transmission quantity is effectively reduced, and the rate and the reliability of the data transmission are effectively improved.

Description

technical field [0001] The invention relates to the field of current monitoring, in particular to a distributed network-based current monitoring method for enterprise electrical equipment. Background technique [0002] With the development of modern technology, industrial and civilian high-power electrical appliances are used more frequently, and the current in the circuit also increases with the increase of power. When the current in the circuit becomes larger, the heat generated by the wire will also increase. , There are certain potential safety hazards, which may easily cause loss of life and property. Therefore, it is necessary to monitor the current in the circuit in real time. When the current exceeds a certain safety threshold, the power can be manually or automatically reduced to reduce the current below the safety threshold. At the same time, how to reasonably allocate resources in modern industry is also a thorny issue. It is often seen that in a company, some ma...
