Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

As shown in figure 1, a kind of anti-infringement control adapter includes control signal input circuit 10, control signal process circuit 20 and control signal output circuit 30, the signal input part of the control signal input circuit 10 is used as this control adapter Signal input part, the signal input part of the signal output part connection control signal process circuit 20 of control signal input circuit 10, The signal input part of the signal output part connection control signal output circuit 30 of the control signal process circuit 20, the control The signal output part of signal output apparatus 30 as this control adapter signal output part.

As shown in Fig. 2 the control signal input circuit 10 includes two structure identical control signal input blocks, two The signal input part of the individual control signal input block is as the signal input part of this control adapter, two controls The signal output part of signal input unit is all connected with the signal input part of control signal process circuit 20.

As shown in Fig. 2 the control signal output circuit 30 includes two structure identical control signal output units, two The signal input part of the individual control signal output unit is all connected with the signal output part of control signal process circuit 20, two institutes The signal output part of control signal output unit is stated as the signal output part of this control adapter.

The control signal process circuit 20 includes fpga chip, the altera corp of the model U.S. of the fpga chip The EP1C12Q240I7N chips of the Cyclone series of production, the chip price is cheap, is adapted to be applied to some simple sequential In operation.

Two control signal input blocks, control signal output unit are U.S. Integrated Device The IDT74FCT164245TPV chips of Technology companies production；The input port number of IDT74FCT164245TPV chips is 16, therefore corresponding delivery outlet number is also 16, the chip is powered using 3.3V with 5V, wherein 3.3V supply ports and fpga chip It is connected, 5V supply ports are connected with external interface, and the signal of IDT74FCT164245TPV chips is moved towards by two control signals Respectively DIR1 and DIR2 is controlled.

The utility model when in use, can coordinate to be used with software of the prior art.With reference to existing Software in technology is described to operation principle of the present utility model, it must be noted that be：Match with the utility model The software of conjunction is not innovative part of the present utility model, nor part of the present utility model.

Signal input part of the TTL input signals respectively with two control signal input blocks is connected, due to TTL input signals It is 5V, TTL input signals is connected to the B ports of IDT74FCT164245TPV chips, therefore IDT74FCT164245TPV cores The A ports of piece export 3.3V signals to EP1C12Q240I7N chips, and the data flow direction of IDT74FCT164245TPV chips is From B ports to A ports, so needing for the OE enable signals of two control signal input blocks to be set to low level, believing DIR1 Number set same with DIR2 signals is low level.It is damaged in order to prevent fpga chip from permanent high level occur in programming program His device, because the permanent high level for now exporting is not to be directly output to device, but is first input into this anti-infringement control switching Device, therefore when TTL input signals reach EP1C12Q240I7N chips by control signal input block, EP1C12Q240I7N Chip needs, when permanent high level is detected, to be set to low level and exported again, therefore will not caused damage other devices.By In EP1C12Q240I7N chips output signal level be 3.3V, it is therefore desirable to by the two paths of signals of EP1C12Q240I7N chips Output is respectively connecting to two signal input parts of control signal output unit, as control signal output unit A ports, two The signal output port of control signal output unit is configured to 5V output ports, and as B ports power for 5V, so two controls The data flow direction of signal output unit is from A ports to B ports, so needs make the OE of two control signal output units Energy signal is set to low level, is high level by the set same with DIR2 signals of DIR1 signals.

In sum, the utility model can imitate and avoid being damaged because fpga chip permanent high level occurs in programming program Evil other devices, so that for related device provides effectively protection.
