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.

Embodiment 1

[0033] Embodiment 1 of the present invention: an intelligent control device for controlling fans based on Lonworks power carrier communication, its structural diagram is as follows figure 1 As shown, it includes: power carrier communication substrate and power electronic device monitoring and control application board. The power carrier communication substrate communicates with the monitoring host through the Lonworks network. The monitoring and control application board communicates with the power carrier communication substrate through the 1O pin. The power electronic device monitoring and control application board includes an overcurrent detection module and a thyristor drive output module. The thyristor drive output module directly communicates with the controlled device.

[0034] 1. Power module:

[0035] The power module adopts a two-stage power conversion circuit, and the first-stage power conversion circuit converts the 220V or 380V AC voltage on the power line into V ...

Embodiment 2

[0051] Embodiment 2 of the present invention: an intelligent control device for controlling electric valves based on Lonworks power carrier communication, which differs from Embodiment 1 only in the circuit part of the monitoring and control application board of the power electronic device. Since the power of electric valves is generally very small, and the forward and reverse running time is only tens of seconds at most, the time is very short; and considering the size of the combination with the valve body, there is no intelligent control device for electric valves. Overcurrent detection module.

[0052] The thyristor drive output module receives the power carrier data output by the PL3120 communication control module. The Neuron controller in the PL3120 chip controls the thyristor on and off, realizes the conduction and shutdown of the motor of the controlled equipment, and can also realize timing control. The essence is Time-sharing conduction, the control method is phase ...

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...
