Description
Technical field
The utility model relates to a kind of test fixture, relates in particular to a kind of GTMU maintainability test fixture.
Background technology
Existing GTMU maintainability test is the slot of GTMU being put into BBU3900 machine box.The circuit board of putting into rear GTMU there is no the part that leaks outside, and cannot measure it with test pencil, can only see that the pilot lamp of outside rule of thumb carrys out failure judgement point when maintenance, and therefore trouble spot judging accuracy rate is extremely low, affects production efficiency, is unfavorable for cost-saving.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of GTMU maintainability test fixture.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises GTMU, interface board circuit, power module, blower module and DC48V power supply, the power output end of described DC48V power supply is connected with the power input of described power module, the power output end of described power module is connected with the power input of described interface card, the power output end of described interface card is connected with the power input of described GTMU, the signal output part of described GTMU is connected by bus with the signal input part of described interface card, the signal output part of described interface card is connected with the signal input part of described blower module.
The beneficial effects of the utility model are:
The utility model realized convenience, intuitively, GTMU maintainability test mode efficiently, realized the important technology of GTMU method for maintaining and broken through; The utlity model has simple to operate, maintainability test rapid and convenient and the high advantage of cost poor benefit.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of GTMU maintainability test fixture described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises GTMU, interface board circuit, power module, blower module and DC48V power supply, the power output end of described DC48V power supply is connected with the power input of described power module, the power output end of described power module is connected with the power input of described interface card, the power output end of described interface card is connected with the power input of described GTMU, the signal output part of described GTMU is connected by bus with the signal input part of described interface card, the signal output part of described interface card is connected with the signal input part of described blower module.
Principle of work of the present utility model is as follows:
The utility model maintainability test fixture is established DC-48V input port and GTMU test socket, power work status indicator lamp, fan work status indicator lamp.Power module becomes the DC-48V direct current of input DC12V direct current and delivers in interface card through inner DC-DC DC converting circuit, interface card converts 12V direct current to DC5V by the DC-DC change-over circuit in plate, again 12V and 5V are delivered in GTMU and blower module and gone, GTMU and fan obtain the rear each self-starting of power supply, and GTMU controls the rotating speed of fan by control bus.
Those skilled in the art do not depart from essence of the present utility model and spirit, can there is various deformation scheme to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalent structure that all utilization the utility model instructionss and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
