Intelligent control device based on Lonworks electric power carrier communication

Abstract

The invention discloses an intelligent control device based on Lonworks electric power carrier communication, which comprises an electric power carrier communication substrate and a power electronic device monitoring controlling application plate. The electric power carrier communication substrate is in communication with a monitoring host through a Lonworks network. The electric power carrier communication substrate comprises a power supply module, a PL3120 communication control module and a coupling circuit. The power electronic device monitoring controlling application plate is in communication with the electric power carrier communication substrate through an input / output (IO) pin. The power electronic device monitoring controlling application plate comprises an over-current detection module and a thyristor drive output module which is directly connected with a controlled device. The intelligent control device based on Lonworks electric power carrier communication is capable of lowering construction cost of a monitoring system and reducing occupied space and difficulty in maintenance at a later stage, and is especially suitable for places where line laying-out cannot continue in civil air-defense construction or occasions when wall chiseling and pipe penetrating absolutely cannot occur after a structure is finished in civil air-defense construction.

Description

technical field [0001] The invention relates to an intelligent control device based on Lonworks power carrier communication, which belongs to the fields of civil air defense engineering and intelligent building equipment automation. Background technique [0002] Civil air defense projects and intelligent buildings are environmental places with relatively complex structures, and the internal equipment such as fans, electric valves, electric control doors, water pumps, etc., all need to realize automatic monitoring. Because it is extremely unsuitable for wireless communication in places with many floors and space occlusions, the automatic monitoring of equipment is realized by configuring a power distribution cabinet with contactors and relays, and adding a group of automated controller cabinets. of. However, this technology needs to lay separate communication cables, set up separate contactors, relay distribution cabinets, and automation controller cabinets. Communication c...

AI Technical Summary

Problems solved by technology

However, this technology needs to lay separate communication cables, set up separate contactors, relay distribution cabinets and automation controller cabinets, which not only costs a lot, takes up a lot of space, but also requires a lot of time for negotiation and negotiation between equipment suppliers. Communication can achieve compatibility between devices, which increases the difficulty of later maintenance

Moreover, this technology is not applicable in places where it is impossible to continue laying lines in civil air defense projects, or when the structure of civil air defense projects must not be cut through the wall after the completion of the pipe.
