Abstract
The utility model provides a dimming actuator based on bus communication. The dimming actuator comprises a power supply electricity-taking filter module, a controller power supply module, a controller, a strong and weak electricity buffer circuit, a dimming actuation circuit, which are sequentially connected; also comprises a message receiving module connected with the controller, a message sending module and a debugging interface. The single multi-core cable is used to replace the traditional separated control cable and the electric power cable, and the switches are ensured to mutually send the control command, thus the bus cable is laid in the linear type, the tree type or the star type, thus the bus cable is conveniently expanded and modified. The element intelligence can change the function of the element by programming, thus the operations such as switch, control and monitor are independently accomplished, and can also be differentially combined according to requirements. Compared with the traditional mounting way, the function multiplication is realized without increasing the number of the elements, therefore the dimming actuator based on bus communication has features of high openness, high reliability, low energy consumption, and high ratio of performance to price.
Description

The utility model relates to the device based on bus, especially based on the device of KNX bus communication, particularly, relates to the light modulation executor based on bus communication.
Background technology
The integrated sophisticated technologies such as modern communication technology, microelectric technique in the intelligent building.The application of these technology, not only brought heavy construction cost pressure to building, its operation and maintenance cost also day by day increases, and simultaneously intelligent construction constantly proposes higher requirement to aspects such as the fail safe of the convenience of construction, use, economy, comfortablenesses.For adapting to such demand, the field bus technique standard europe installation bus of building field---EIB (Europeaninstallation Bus) just arises at the historic moment
The EIB technology is once breakthrough revolution for the conventional electrical mounting technique, and it has the core advantage of field bus technique, and such as full decentralized control, design, installation, easy to maintenance etc. are the very outstanding standard for Fieldbus of current technical field of buildings.EIB is the distributed bus system of an event based control.System adopts that serial data communication is controlled, monitoring and status report.All bus units all connect (being bus) mutually exchange message by the serial transmission of sharing.Transfer of data is carried out according to the determined rule of bus protocol, the information that needs to send is packed first, form standard transmission formats (being message), then be sent to one or more final controlling elements (order recipient) by bus from a sensing device (order sender).The transfer of data of EIB and the power supply of bus unit (DC 24V) share a cable, and message is modulated on the direct current signal
The utility model content
For defective of the prior art, the purpose of this utility model provides a kind of light modulation executor based on bus communication.
According to an aspect of the present utility model, a kind of light modulation executor based on bus communication is provided, it is characterized in that, comprise the power supply power taking filtration module, controller supply module, controller, strong and weak electricity buffer circuit, the light modulation executive circuit that connect successively, also comprise the message receiver module, message sending module, the debugging interface that connect described controller.
Preferably, the model of the central processing unit that comprises of described controller is STM32F103.
Preferably, also comprise the KNX bus, described power supply power taking filtration module, message receiver module and message sending module all connect described KNX bus.
Preferably, also comprise preset mode download interface, address and the preset mode memory cell that connects described controller.
Preferably, also comprise the zero-detection circuit that connects described controller.
Preferably, also comprise the forceful electric power protective circuit that connects described light modulation executive circuit.
The utility model has substituted control cables and the power cable of traditional separation by single multicore cable, and guarantees the mutually transmission control instruction processed of each switch, so bus cable can with line style, tree type or star-like laying, make things convenient for dilatation and repacking.The intellectuality of element makes it change function by programming, but both work such as complete independently such as switch, control, supervision also can be carried out different combinations as requested.Compare with the conventional mounting mode, the utility model does not increase number of elements and has realized the function multiplication, thereby has had the flexibility of height, has the advantages that opening is high, reliability is high, energy consumption is low, cost performance is high.
