Embodiment 1
As shown in Figure 1, a kind of method that the present embodiment provides LED lamp point current failure to get rid of, described method comprises and pre-sets step and set-up procedure, the current failure that can get rid of each LED lamp point by described method, make each LED lamp point before there is current failure, can find in time to occur the possibility of current failure, thereby the possibility breaking down is excluded, or, when there is current failure in each LED lamp point, prevent from resulting in greater loss, to guarantee to make each LED lamp point can be always in stable operating state.
Wherein, the described step that pre-sets comprises: in first step A, setting and external LED screen, each LED lamp is put current data cell list one to one, according to the quantity of each LED lamp point in external LED screen, and corresponding position arranges the current data cell list with each LED lamp point one-to-one relationship, wherein, described LED screen refers to various LED displays and various LED lamp decoration screen; And, input the normalized current data of each LED lamp point, described normalized current data can be the optimum current data of each LED lamp point work, can be a concrete numerical value, or, can be also a certain range values; Described current data cell list can arrange by software in the control unit of described LED screen, also can be by arranging with the PC of described control unit.
For example, before current data unit is set, can also be according to the ranks position of each LED lamp point place LED screen, set the coordinate figure of each LED lamp point, thereby by each lamp, put corresponding coordinate figure, set its corresponding described current data cell list, so, can make the setting of described current data cell list simpler, easy to use.
Second step B, after setting described current data cell list, also store described current data cell list, in order to calling, for example, can be by memory module is set, or arrange one movably memory store described current data cell list, by removable memory, can also facilitate movement and the replacing of data.
Described in carrying out, pre-set after step, also carry out described set-up procedure, comprising: the 3rd step C, actual current data while detecting a certain LED lamp point work, for example, detect in real time in described LED screen the current data of whole LED lamp points or the work of part LED lamp point, or, whole LED lamp points or part LED lamp point detected in described LED screen sometime or in current data sometime section; Wherein, can be according to actual needs, by detecting the current data of whole LED lamp point work in LED screen, can get rid of the current failure of each LED lamp point, or, by detecting the current data of part LED lamp point work in LED screen, can, by representative part LED lamp, analyze whether there is current failure or whether has current failure hidden danger of whole LED lamp points, thereby can simplify the operation of each step, each step operation is more prone to, also convenient.
Or, can also detect each LED lamp point and whether leak electricity, while there is electric leakage as each LED lamp point, export electric leakage signal, for example, by indicator light, siren generation alarm signal, or, also can export described electric leakage signal to described PC, by described PC, show and warn, thereby remind staff to have electric leakage accident, should process in time, avoid occurring critical failure, thereby described LED screen is damaged, or, affect the demonstration of each LED lamp point.
Carry out after the 3rd step C, continue to carry out the 4th step D, the actual current data of each LED lamp point detecting are contrasted with its corresponding normalized current data in described current data cell list, and, generate difference reduced value, and judge described in it whether difference reduced value is greater than a preset value, for example, the normalized current data that the actual current of a certain LED lamp point X is corresponding with LED lamp point X in described current data cell list contrast, generate difference reduced value, and judge described in it whether difference reduced value is greater than a preset value; Wherein, described difference reduced value refers to, the ratio of one difference and normalized current data, described difference is the difference of its actual current data and its normalized current data, for example, the actual current numerical value of LED lamp point X is 10.1mA, and LED lamp point X is 10mA in the normalized current data of described current data cell list, described difference is 0.1mA, and described difference reduced value is 1%.
Wherein, described preset value is, set according to actual needs, the operating current error amount that its normalized current data value allows relatively that is generally corresponding LED lamp point, for example, described preset value is 1%, 1.5%, 2%, 2.5% or 3%, or, described preset value can be also a range values, for example, is 0 to 1%, 0 to 1.5%, 0 to 2%, 0 to 2.5%, 0 to 3% etc.
When described difference reduced value is less than or equal to described preset value, illustrate that each LED lamp point is in metastable operating state, each LED lamp point no current fault, and, there is not the possibility that current failure occurs.
When described difference reduced value is greater than described preset value, perform step the 5th step E, according to the normalized current data of this LED lamp point in described current data cell list, adjust the input current of this LED lamp point, for example, can adjust by adjusting module is set the input current of each LED lamp point, wherein, particularly, can adjust by resistance is set the input current of each LED lamp point, or, by adjusting the voltage of each LED lamp point input, adjust the input current of each LED lamp point, thereby in the current value range of the input current that makes each LED lamp point in allowing, thereby get rid of the possibility that current failure occurs each LED lamp point.
An example is, in carrying out described set-up procedure, the 3rd step can specifically carry out C1, each actual current data when detecting respectively each row or being respectively listed as the work of LED lamp point, the actual current data in the time of can detecting respectively each LED lamp point work by branch or apportion, thereby can improve the efficiency of detection, reduce the difficulty detecting; And, the 4th step D1 carries out, respectively by each row or be respectively listed as LED lamp point actual current data separately and contrast with normalized current data corresponding in described current data cell list, thereby can generate respectively each row of each LED lamp point or respectively be listed as corresponding difference reduced value, and, judge respectively whether it is greater than described preset value, when described difference reduced value is greater than described preset value, carry out the 5th step E1, according to the normalized current data of each corresponding LED lamp point in described current data cell list, adjust the input current of each corresponding LED lamp point.
Another each example is, in carrying out described set-up procedure, the 3rd step can specifically be carried out C2, each actual current data while detecting each LED lamp point work of full screen, each actual current data while detecting each the LED lamp point work in LED screen, and the 4th step D2, respectively the actual current data separately of each the LED lamp point in LED screen are contrasted with normalized current data corresponding in described current data cell list, generate the difference reduced value of each LED lamp point, and then judge respectively whether it is greater than a preset value, when described difference reduced value is greater than described preset value, carry out the 5th step E2, according to the normalized current data of each corresponding LED lamp point in described current data cell list, adjust the input current of each corresponding LED lamp point.So, can complete detection described in the operating current state of each LED lamp point in LED screen, thereby can get rid of the current failure of each LED lamp point.
