The safe processor, the general-purpose processor and the core area are all arranged on the PCB of the motherboard. The safe processor is arranged in the core area. The multimedia-POS-based heat-radiation-optimized motherboard is characterized in that the general-purpose processor is arranged on one side of the PCB of the mother board, which is opposite to the safe processor. The multimedia-POS-based heat-radiation-optimized motherboard has a remarkable heat radiation effect and settles a problem of inferior heat radiation in the existing multimedia POS motherboard and the terminal.
Description
Technical field
The utility model relates to a kind of mainboard and terminal of the optimizing thermal solution based on multimedia POS.
Background technology
Multimedia POS payment terminal for example, for example, by general processor (Cortex A8) and safe processor (MAXQ1850) as equipment master chip, the application programs such as general processor operation displaying of graph and image, safe processor is responsible for the anti-invasion function of whole POS terminal, general processor is responsible for displaying of graph and image, if cross the authentication of POS terminal security, traditional interior layout is that general processor and safe processor all will be placed on and have in the nucleus that intrusion detection circuit PCB surrounds, and prevents that liquid crystal display content is tampered.General processor needs heat radiation in when work, is placed in the nucleus that PCB surrounds the object that is unfavorable for reaching heat radiation due to narrow space and closure.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of mainboard and terminal of the optimizing thermal solution based on multimedia POS, solves existing multimedia POS mainboard and the bad problem of heat dissipation of terminal.
The utility model is achieved in that
A kind of mainboard of the optimizing thermal solution based on multimedia POS, comprise safe processor, general processor and there is the nucleus that intrusion detection circuit PCB surrounds, described safe processor, general processor and nucleus are all arranged on the PCB of mainboard, described safe processor is inner at nucleus, and described general processor is arranged on the upper side contrary with safe processor of PCB of mainboard.
Further, the central axis of described general processor is in nucleus.
Further, the central axis of described general processor is in safe processor surface.
Further, the central axis of described general processor is in safe processor centre of surface place.
Further, described general processor is BGA encapsulation.
Further, described general processor surface is provided with heat radiator.
And the utility model also provides a kind of terminal of the optimizing thermal solution based on multimedia POS, include a mainboard, card-brushing groove, display screen and keyboard, described mainboard is the mainboard of above-mentioned any one optimizing thermal solution based on multimedia POS.
The utility model has the advantage of: general processor is placed on the safe processor back side, be not subject to the covering of the intrusion detection circuit PCB on nucleus, be in the space of not sealing, the heat sending during chip operation has larger space heat elimination.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
Refer to shown in Fig. 1, below will be elaborated to the utility model.
A kind of mainboard of the optimizing thermal solution based on multimedia POS, comprise safe processor 1, general processor 2 and there is the nucleus 3 that intrusion detection circuit PCB surrounds, safe processor 1, general processor 2 and nucleus 3 are all arranged on the PCB(printed circuit board of mainboard) on 4, safe processor 1 is in nucleus 3 inside, and general processor 2 is arranged on the upper side contrary with safe processor 1 of PCB4 of mainboard.General processor 2 is arranged on to the area of dissipation that nucleus 3 outsides have increased general processor 2 greatly, has avoided the accumulation of heat in nucleus 3.
Because safe processor 1 itself has temperature detecting function, once temperature overruns, can cause mainboard lock machine.The central axis of general processor 2 is in nucleus 3, the temperature of general processor 2 is because heat is delivered to safe processor 1.When mainboard moves, the high temperature of safe processor 1 and low temperature measuring ability are opened, can be realized the temperature detection to general processor 2.In order to realize better detection effect, preferably the central axis of general processor 2 is in safe processor 1 surface.In the situation that PCB layout allows, the central axis that most preferably is general processor 2 is in safe processor 1 centre of surface place, and general processor 2 and safe processor 1 are placed on TOP face and the overlapped position of BOTTOM face of mainboard PCB4.
In order to strengthen the security of general processor 2, the encapsulation of general processor 2 adopts BGA encapsulation.The PIN pin of general processor 2 is hidden in chip package the inside like this, and the external world can not survey.In order further to strengthen the radiating effect of general processor 2, the surface of general processor 2 is provided with heat radiator (Fig. 1 is not shown).
And the utility model also provides a kind of terminal of the optimizing thermal solution based on multimedia POS, include a mainboard, card-brushing groove, display screen and keyboard, described mainboard is the mainboard of the above-mentioned optimizing thermal solution based on multimedia POS.Card-brushing groove, display screen and keyboard are all connected with mainboard respectively.Adopt the terminal of the mainboard of the above-mentioned optimizing thermal solution based on multimedia POS to there is good radiating effect.
To sum up, the utlity model has good heat dissipation effect, can guarantee the safety of general processor 2 again simultaneously.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
