Background technology

Current light fixture circuit controls major part is to use time controller and A.C. contactor to combine and be timed on-off control, if changing timing, the position that must arrive in-site installation time controller is modified the time, very inconvenient like that, lost labor's expense, safeguard also not in time, it is impossible to the quality of detection time controller。

Utility model content

The purpose of this utility model is to provide a kind of light fixture loop control system, and it, without carrying out relevant setting to scene, uses more convenient。

To achieve these goals, this utility model adopts the following technical scheme that

Light fixture loop control system, including host computer, Centralized Controller, terminal controller, A.C. contactor and light fixture；Host computer and Centralized Controller are bi-directionally connected, and are communicatively coupled wirelessly between Centralized Controller and terminal controller, and A.C. contactor and light fixture are sequentially connected to the outfan of terminal controller；

Described terminal controller includes power module, MCU control unit, current/voltage collecting unit, controls dimming unit, power line carrier unit and overload protection unit；Working power is provided for whole terminal controller by power module; current/voltage collecting unit is connected to the Gather and input end of MCU control unit; power line carrier unit and MCU control unit are bi-directionally connected; control dimming unit and overload protection unit are connected to the corresponding output end of MCU control unit; the outfan controlling dimming unit connects the input of above-mentioned A.C. contactor, and controls to be provided with the timing controller controlling light fixture work schedule in dimming unit。

After adopting such scheme, light fixture loop control system of the present utility model, the lamp switch time can be set by host computer or light fixture is dimmed, Centralized Controller and host computer carry out information exchange, and communicated by the MCU control unit of the power line carrier unit of terminal controller Yu terminal controller, the timing controling signal of light fixture or dim signal are conveyed to the MCU control unit of terminal controller, MCU control unit exports corresponding control signal to controlling dimming unit, by controlling dimming unit, light fixture is carried out brightness adjustment control, simultaneously, the break-make of A.C. contactor is controlled to realize lighting or extinguishing control of light fixture by controlling the timing controller in dimming unit, thus realizing the control of lamp switch time。Light fixture loop control system of the present utility model, it is not necessary to arrange to scene, uses easily。And, timing controller communicates with host computer in real time, if communication disruption, then illustrates that timing controller breaks down, such that it is able to detect the quality of timing controller in real time, so that timing controller is safeguarded by staff in time。

Detailed description of the invention

Light fixture loop control system of the present utility model, as it is shown in figure 1, include host computer 1, Centralized Controller 2, terminal controller 3, A.C. contactor 4 and light fixture 5；Host computer 1 and Centralized Controller 2 are bi-directionally connected the information of carrying out exchange, are communicatively coupled wirelessly between Centralized Controller 2 and terminal controller 3, and A.C. contactor 4 and light fixture 5 are sequentially connected to the outfan of terminal controller 3。

As in figure 2 it is shown, terminal controller 3 includes power module 31, MCU control unit 32, current/voltage collecting unit 33, controls dimming unit 34, power line carrier unit 35 and overload protection unit 36。

Working power is provided for whole terminal controller 3 by power module 31。

Current/voltage collecting unit 36 is connected to the Gather and input end of MCU control unit 32; overload protection unit 36 is connected to the corresponding output end of MCU control unit 32; power line carrier unit 35 and MCU control unit 32 are bi-directionally connected, and Centralized Controller 2 is communicated by power line carrier unit 35 with MCU control unit 32。

Current/voltage collecting unit 36 is in order to gather the parameters such as the voltage of light fixture 5, electric current, power, and MCU control unit 32 detects the voltage of light fixture 5, electric current, the value of power in real time and by power line carrier unit 35, testing result is uploaded to Centralized Controller 2。When MCU control unit 32 detects the value off-rating of the voltage of light fixture 5, electric current, power, MCU control unit 32 sends overload protection signal to overload protection unit 36, overload protection unit 36 action, and protection light fixture 5 is not burned。

Controlling dimming unit 34 and be connected to the corresponding output end of MCU control unit 32, the outfan controlling dimming unit 34 connects the input of A.C. contactor 4, and controls to be provided with the timing controller controlling light fixture 5 work schedule in dimming unit 34。

As shown in Figure 3, R, S, T, N represents the input of three-phase electricity and zero line respectively, QF1, QF2 all represents chopper, KM1, KM2 represents A.C. contactor respectively, OUT represents terminal controller, SB1, SB2, SB3, SB4 represents the button of distribution box respectively, when terminal controller exports 220V voltage, A.C. contactor KM1, the coil electricity of KM2, A.C. contactor KM1, KM2 closes, its main contact and auxiliary contact all electric adhesive, overall circuit energising, light fixture 5 is made to open, when terminal controller 3 does not have output voltage, A.C. contactor is in open-circuit condition, light fixture is closed。

Light fixture loop control system of the present utility model, during work, host computer 1 can be passed through arrange the lamp switch time or light fixture is dimmed, Centralized Controller 2 and host computer 1 carry out information exchange, and communicated by the MCU control unit 32 of the power line carrier unit 35 of terminal controller 3 with terminal controller 3, the timing controling signal of light fixture or dim signal are conveyed to the MCU control unit 32 of terminal controller, MCU control unit 32 exports corresponding control signal to controlling dimming unit 34, by controlling dimming unit 34, light fixture 5 is carried out brightness adjustment control, simultaneously, the break-make of A.C. contactor 4 is controlled to realize lighting or extinguishing control of light fixture 5 by controlling the timing controller in dimming unit 34, thus realizing the control of lamp switch time。Light fixture loop control system of the present utility model, it is not necessary to arrange to scene, uses easily。And, timing controller communicates with host computer in real time, if communication disruption, then illustrates that timing controller breaks down, such that it is able to detect the quality of timing controller in real time, so that timing controller is safeguarded by staff in time。
