Abstract
The utility model provides a test mainboard with multi -programming is compatible, including the plate body and set up in the master control IC of plate body, still include with a plurality of toggle switch of master control IC electric connection, toggle switch has two gears, corresponds high level gear, low level gear respectively. The beneficial effects of the utility model are that: change toggle switch's state combination, transfer a test program who saves promptly in it to correspond the test of product, satisfy the test of a test mainboard to the fecund article.
Description
Technical field
The utility model relates to LED screen display technique field, particularly a kind of testing host with multiprogram compatibility.
Background technology
The production line of LED screen, it produces a product respective production one program test plate; When another product changed by needs, then need separately to make a program test plate, or, change another program, then just can carry out the test of product.Therefore, present production line, namely change product needs change program test plate or change test procedure.
Utility model content
In order to solve above-mentioned existing technical matters, the utility model provides a kind of testing host with multiprogram compatibility, changes the combinations of states of toggle switch, namely calls the test procedure stored in it, thus carry out the test of corresponding product, meet a testing host to the test of multi-product.
The utility model solves above-mentioned existing technical matters, provides a kind of testing host with multiprogram compatibility, comprises plate body and is arranged at the master control IC of described plate body, also comprise the multiple toggle switches be electrically connected with described master control IC; Described toggle switch has two gears, respectively corresponding high level gear, low level gear.
The utility model further improves as described below.
Described toggle switch has supply voltage contact, digitally or in analog contact.
The topworks of described toggle switch connects supply voltage contact, and corresponding described toggle switch is high level gear.
The topworks of described toggle switch connects digitally or contact in analog, and corresponding described toggle switch is low level gear.
The quantity of described toggle switch is greater than 3.
Compared to prior art, the beneficial effects of the utility model are: the combinations of states changing toggle switch, namely call the test procedure stored in it, thus carry out the test of corresponding product, meet a testing host to the test of multi-product.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the testing host of multiprogram compatibility.
| Plate body 11 | Master control IC12 |
| Toggle switch 13 |
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, a kind of testing host with multiprogram compatibility, the multiple toggle switches 13 comprising plate body 11, be arranged at the master control IC12 of plate body 11, be electrically connected with master control IC12; Toggle switch 13 has two gears, respectively corresponding high level gear, low level gear.Change the combinations of states of toggle switch 13, namely call the test procedure stored in it, thus carry out the test of corresponding product, meet a testing host to the test of multi-product.
The utility model toggle switch 13 has supply voltage contact, digitally or in analog contact.The topworks of toggle switch 13 connects supply voltage contact, and corresponding toggle switch 13 is high level gear.The topworks of toggle switch 13 connects digitally or contact in analog, and corresponding toggle switch 13 is low level gear.
The quantity of the utility model toggle switch 13 is greater than 3.Suppose, the quantity of its toggle switch 13 is 4, is respectively 1,2,3,4, and when toggle switch 131,2,3,4 is all low level gear, control IC judges that combinations of states is 0000; When toggle switch 131 is high level gear, 2,3,4 when being low level gear, and control IC judges that combinations of states is 0001; In like manner, when toggle switch 131,2,3,4 is all high level gear, control IC judges that combinations of states is 1111.Master control IC12 receives corresponding combinations of states, can judge the program that district office needs, to recall corresponding test procedure, thus reach compatible effect by IF statement contrast.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
Claims (5)
1. there is a testing host for multiprogram compatibility, comprise plate body and be arranged at the master control IC of described plate body, it is characterized in that:
