Description
Technical field
The utility model relates to the control technology field of LED display, particularly relates to a kind of driving control system of intelligent LED display.
Background technology
LED display is spliced by multiple little display unit; each display unit; independently AC/DC electric supply system is all equipped with; the Switching Power Supply of substantial amounts; the moment started at the same time, dash current is very huge, often causes the phenomenons such as earth leakage circuit-breaker tripping operation; each power supply is positioned at single display unit inside simultaneously, also causes obstacle to subsequent maintenance.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of driving control system of intelligent LED display.
The utility model is achieved through the following technical solutions:
A kind of driving control system of intelligent LED display; outside three-phase ac-input power supply directly connects earth leakage circuit-breaker; earth leakage circuit-breaker is connected to multiple D.C. contactor; described multiple D.C. contactors are connected with MCU respectively; multiple D.C. contactor also turns DC power supply with multiple AC respectively and is connected; multiple AC turns DC power supply and is connected to multiple display unit, and described MCU is also connected with multiple display unit respectively.
The utility model has the advantages that: high pressure AC/DC power supply is concentrated and is positioned in power distribution cabinet by the utility model, by MCU unified management, set a suitable output voltage and export display casing to, power supply is provided with redundancy feature simultaneously, power supply output state is detected in real time by MCU, fault is had to switch at any time and failure problems is sent to control end in time, to arrange maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; a kind of driving control system of intelligent LED display; outside three-phase ac-input power supply 104 directly connects earth leakage circuit-breaker 101; earth leakage circuit-breaker 101 is connected to multiple D.C. contactor 102; described multiple D.C. contactors 102 are connected with MCU100 respectively; multiple D.C. contactor 102 also turns DC power supply 103 with multiple AC respectively and is connected; multiple AC turns DC power supply 103 and is connected to multiple display unit 201, and described MCU100 is also connected with multiple display unit 201 respectively.
Outside three-phase ac-input power supply directly accesses earth leakage circuit-breaker 101, by being connected to D.C. contactor 102 respectively after protection switch 101, the control signal of D.C. contactor 102 is exported by MCU100, MCU model is STC12C5A60S2, corresponding output port is L0, L1Ln (determine according to the quantity of direct contactor by output port, and each port successively the court of a feudal ruler time startup in about 3 seconds), when control terminal sends starting-up signal, port L0 exports high level, one of them direct contactor is opened, AC turns DC power supply 103 and exports a high direct voltage to display unit 200, this group display unit corresponding is started working, after port L0 exports 3 seconds, port L1 also exports a high level, and corresponding second group of display unit is started working, and it is wide that the rest may be inferred, thus reach the effect of timesharing startup.
We are provided with feedback signal A on each group display unit in addition, and by detection signal A, MCU judges that power supply exports the automatic switchover whether normally realizing power supply redundancy, and feed back to control terminal simultaneously.
In order to reduce the wastage, it is a high direct voltage that AC/DC conversion electric power 103 exports usually, and is directly placed in power distribution cabinet, and it has redundancy and warm connection function, is convenient for changing, and does not affect whole screen work.
