Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0034] figure 1 Among them, the distributed harmonic online detection system based on the construction equipment Internet of Things includes several harmonic detection terminals 1, several wireless network / Ethernet gateways 2, servers (including application server 3, database server 4 and WEB server 5 ).

[0035] According to needs, multiple harmonic detection terminals 1 can be installed on the sockets of each important electrical equipment that users care about, or they can be installed only on distribution branches such as lighting, air conditioning, or power, or only one on the outlet side of the transformer. Harmonic detection terminal 1. Harmonic detection terminal 1 is responsible for collecting voltage and current signals of corresponding equipment or lines, and calculating harmonics and effective values ​​of voltage and current. The harmonic detect...

Abstract

The invention relates to a distributed type on-line harmonic detecting system based on Internet of construction equipment. The distributed type on-line harmonic detecting system comprises a plurality of harmonic detecting terminals, a plurality of wireless network/Ethernet gateways and a plurality of servers, wherein the respective harmonic detecting terminals are connected with the servers through corresponding wireless network/Ethernet gateways; the respective harmonic detecting terminals are used for acquiring voltage signals and current signals of corresponding equipment or circuits and calculating effective values and respective harmonics of voltage and current; the wireless network/Ethernet gateways are used for realizing the bidirectional forwarding of information between a wireless network and an Ethernet network; and the server comprises an application server, a database server and a WEB server, and is used for realizing the display, storage, off-limit alarm and WEB release of harmonic data. When the distributed type on-line harmonic detecting system is adopted, large-capacity information storage, more attractive interface and more convenient operation are realized; as the data is released through the Internet, the purposes of realizing on-line monitoring and giving an alarm in time can be achieved; and therefore the distributed type on-line harmonic detecting system can be used for detecting harmonic conditions in a building, and can be applied to other occasions with higher requirements for the quality of electric energy.

Description

technical field [0001] The invention relates to a distributed harmonic online detection system based on the internet of things of construction equipment. Background technique [0002] In recent years, with the rapid development of modern science and technology, major changes have taken place in the structure of power loads in civil building power distribution systems, and loads such as semiconductor rectifiers, thyristor voltage regulators, and frequency conversion adjustment devices have developed rapidly. On the one hand, these modern electrical equipment have higher requirements on power quality than traditional equipment, and are vulnerable to impact; on the other hand, these equipment based on power electronics technology and computer technology have load nonlinearity, impact and unbalanced power consumption. The characteristics make the waveform distortion of the power distribution system of civil buildings more and more serious, and the interference or pollution to th...
