Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be done to simple introduction below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Embodiment
Below by specific embodiment, the utility model is further described.
The remote LED display screen self diagnosis control system of the present embodiment, comprise long-range main control end computer or mobile phone, GPRS communication module 7, current transducer 2, solid-state relay 3, single-chip microcomputer 4, LED display, LED display comprises Switching Power Supply group 1, control card 5 and LED display cell board 6, control card 5 connects single-chip microcomputer 4, single-chip microcomputer 4, control card 5 are connected with GPRS communication module 7 respectively, and the output terminal of control card 5 also connects LED display cell board 6; 7 Information Monitorings of GPRS communication module also send to long-range main control end computer or mobile phone by mobile gprs system.Single-chip microcomputer 4 connects solid-state relay 3 and current transducer 2, and current transducer 2 is connected with Switching Power Supply group 1.Single-chip microcomputer 4 connects temperature sensor 8, and is connected with radiator fan 9 by solid-state relay 3.
Remote LED display screen self diagnosis control system adopts single-chip microcomputer 4 to control, and by sending instruction to control card 5, obtains the state of control card 5, if having to respond, represents that control card 5 is in good condition, if do not responded, represents that control card 5 damages; Single-chip microcomputer 4 sends the specific display of corresponding LED display cell board 6 to control card 5, by control card 5, sending to LED display shows, and gather the working current of the different pattern of LED display cell board 6, according to the variation of electric current, judge the fault of LED display cell board 6.By GPRS communication module 7, send information to long-range main control end computer or mobile phone, notify the show state of staff's LED display, also can long-rangely by information, open or close display screen.The temperature that single-chip microcomputer 4 is measured in LED display casing by temperature sensor 8, if surpass design temperature, opens radiator fan 9 and lowers the temperature, and guarantees the safety of equipment, avoids unnecessary fault.
For large LED display screen, because power supply generally adopts Switching Power Supply, to open moment and belong to capacitive load, dash current is larger, so the general power lead thickness of selecting is than large one or several rank of actual needs.In remote LED display screen self diagnosis control system, Switching Power Supply group 1 is comprised of the Switching Power Supply of several 200W, and wherein the quantity of Switching Power Supply is determined by the size of LED display; Each current transducer 2 is measured the electric current of corresponding Switching Power Supply group 1, can be according to the quantity of the quantity increase and decrease current transducer of Switching Power Supply group 1; System adopts single-chip microcomputer 4 to control, and can sequentially open each Switching Power Supply group 1, avoids the impact of larger Current on Grid, makes the inlet wire of power supply select to approach the actual power that uses, and reduces costs, and avoids waste.
Applied specific embodiment herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
