Embodiment
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model has disclosed a kind of LED display electric power controller, comprise the panel box of controlling LED display, also comprise remote control, be connected the power-supply controller of electric that is used for distribution control box work with panel box, be connected with power-supply controller of electric and be used for completing the radio communication device of communicating by letter between remote control and power-supply controller of electric.For the safety of communicating by letter, also be provided with in described power-supply controller of electric be used to receive the steering order signal and verify authentication module.
In the present embodiment, use PC as remote control, use the GPRS/3G module as radio communication device.PC arrives the GPRS/3G module by Internet connection, communicates by letter thereby set up with power-supply controller of electric.Considering that PC and GPRS/3G module setting up when communicating by letter, is all to seek the other side by the IP address.In general, during GPRS/3G wireless access internet, the IP address of each network allocation is all unfixed, and the access way majority of the PC accessing Internet that the keeper uses is all fixing IP, so can set up communication by the mode that the GPRS/3G module is initiatively sought PC.In fact, PC may be also the mode accessing Internet by dialing, its IP is also Random assignment, all the problem of not fixing IP in order to solve communicating pair, can adopt the mode of DDNS to set up communication, be DDNS of PC configuration, thereby the GPRS/3G module can be sought PC by the DDNS of PC and sets up with PC and communicate by letter.
After setting up communication, operating personnel's PC sends to steering order Ctr on power-supply controller of electric by the Internet, power-supply controller of electric receives after instruction the correctness by its authentication module checking (can by modes such as check code or passwords) steering order Ctr, if steering order Ctr is by verifying power-supply controller of electric send Ctr signal (low level or high level) to panel box according to command content (opening or closing) changes steering order otherwise abandon.
As shown in Figure 2, described panel box comprises the light current switch module that is connected to power-supply controller of electric, and the forceful electric power switch module that is connected to the forceful electric power circuit by main breaker 3, the control that the light current switch module is realized the forceful electric power switch module by light-current relay 12; Described light-current relay comprises and is connected in light current switch module light-current relay coil 121 and is arranged at forceful electric power switch module light-current relay normally opened contact to 122.
Described light current switch module comprises triode 11, and triode 11 emitters connect an end of light-current relay coil 121, and base stage connects power-supply controller of electric, grounded collector by resistance 13; Light-current relay coil 121 other ends are connected with power supply.Described forceful electric power switch module comprise a plurality of A.C. contactors of being connected to and being used for controlling LED display with and a plurality of time relays 22 that are used for controlling A.C. contactor that connect one to one with A.C. contactor, A.C. contactor is by 122 pairs of light-current relay normally opened contacts and forceful electric power connection.Described A.C. contactor comprise the ac contactor coil 23 that is connected with the time relay 22 and the A.C. contactor normally opened contact controlled by ac contactor coil 23 to 24, the A.C. contactor normally opened contact is to 24 1 ends and forceful electric power connection, the other end is connected to LED display, and power-supply controller of electric is finally realized the break-make control of LED display power supply by the working power of control time relay 22 and light-current relay 12 and then control A.C. contactor.And be provided with A.C. contactor isolating switch 26 between 24 pairs of A.C. contactor normally opened contacts and forceful electric power road.
In the present embodiment, panel box adopts the three-phase five-wire mode mode to power, and L1, L2, L3 are three live wires of three-phase electricity, and N is zero line, and PE is ground wire.Main breaker 3(three-phase air switch) as master switch, be kept closed.
The Ctr signal is controlled the base stage of triode 11 by resistance 13.When instruction was " opening ", Ctl was low level, triode 11 conductings, and the light-current relay coil 121 of light-current relay 12 produces electric adhesives, thereby drives the light-current relay normally opened contact to 122 closures.The light-current relay normally opened contact to 122 closures after, electric current flows to the time relay 22 and pilot lamp through protective tube F1.Its normally open contacts of time closing after the time relay 22 energising make the ac contactor coil 23 electric adhesive of rear generation that powers on after closure, the A.C. contactor normally opened contact is to 24 closures, thereby power to display screen.
Because LED display generally all is comprised of a plurality of LED modules, also might have simultaneously such as the electrical appliances such as air-conditioning equipment that are used for heat radiation, so can arrange according to actual needs a plurality of A.C. contactors with and the time relay one to one, be each different electrical appliances power supply, its principle of work is amateurish above-mentioned identical.When being provided with a plurality of time relay, can be set respectively the time-delay pickup time of each time relay, thereby time segment can reduce to the power supply of each different LED module the impact that large power-consuming equipment brings to building and electrical network like this.
In order to prevent thunderbolt or the phenomenons such as surge, be provided with also that an end and main breaker are connected in series, the lightning protection device of other end ground connection 4, when having thunderbolt to occur, its is understood relate to the surge voltage that produces on circuit and is put in the PE the earth, has ensured the safety of whole electric power system.
Simultaneously, also be provided with and be connected to the forceful electric power circuit for the one or more hand switches 5 that use to other electrical appliance equipment, each hand switch 5 all connects (also can directly use separately switch disconnector 6) by hand switch isolating switch 6.Hand switch can be connected to the electrical appliance of the interior ventilating system of LED display, illuminator, maintenance use etc.When LED display need to be overhauled, operating personnel can use these hand switches to complete service work.
The present embodiment is more excellent embodiment of the present utility model; need to prove; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection domain of the appended claim of the utility model.
