Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearer, referring to accompanying drawing alsoFor embodiment, the present invention is described in more detail.
Refer to Fig. 1, in one embodiment, path switching device 30 comprises:
The first switch unit 31, has of first network equipment 11 and the first checkout equipment 21 conductingsOne gear 31a and by the second gear 31b of first network equipment 11 and the second checkout equipment 22 conductings;
The second switch unit 32, has of second network equipment 12 and the first checkout equipment 21 conductingsThree gear 32a and by the fourth speed position 32b of second network equipment 12 and the second checkout equipment 22 conductings;
Logical block 33, by gathering power supply signal S1 and second checkout equipment of the first checkout equipment 2122 power supply signal S2 detects the state of the first checkout equipment 21 and the second checkout equipment 22, for example,Logical block 33 can be by the USB (Universal of the first checkout equipment 21 and the second checkout equipment 22SerialBus, USB) interface gathers respectively power supply signal S1 and S2;
And logical block 33 is according to testing result control the first switch unit 31 and the second switch unit32 switch gear makes to form guiding path between first network equipment 11 and second network equipment 12.
Above-mentioned switching gear can be understood as, and the first switch unit 31 and the second switch unit 32 are cut respectivelyChange to the first gear 31a and third gear 32a, or, the first switch unit 31 and the second switch unit32 switch to respectively the second gear 31b and fourth speed position 32b, that is, and and first network equipment 11 and the second netNetwork equipment 12 and same checkout equipment conducting.
Correspondingly, as shown in Figure 2 a, when the first switch unit 31 and the second switch unit 32 switch respectivelyDuring to the first gear 31a and third gear 32a, between first network equipment 11 and second network equipment 12Can form guiding path P1 by the first checkout equipment 21; As shown in Figure 2 b, when the first switch unit31 and second switch unit 32 while switching to respectively the second gear 31b and fourth speed position 32b, first networkBetween equipment 11 and second network equipment 12, can form guiding path P2 by the second checkout equipment 22.
Visible, in this embodiment, logical block 33 detects and establishes according to the first checkout equipment 21 and secondStandby 22 state, can control the gear switch of the first switch unit 31 and the second switch unit 32, withSupport checkout equipment to dispose by the active and standby switching between the first checkout equipment 21 and the second checkout equipment 22High reliability.
And, right to realize in order to identify the state of the first checkout equipment 21 and the second checkout equipment 22The control of gear switch, logical block 33 can gather the first checkout equipment 21 and the second checkout equipment 22Power supply signal S1 and S2, and do not need to depend on first network equipment 11 and second network equipment 12,Therefore, the first checkout equipment 21 and the second checkout equipment 22 can be by first network equipment 11 and secondThe network equipment 22 perception.
Thereby, can avoid the high reliability subordinate of checkout equipment and the unaware of checkout equipment and transparentThe characteristic entering is runed counter to.
In the first checkout equipment 21 and the second checkout equipment 22, can default setting the first checkout equipment 21 beHost apparatus, correspondingly:
When the state of the first checkout equipment 21 is while being normal, logical block 33 can not considered the second detectionEquipment 22 state now, and logical block 33 can be controlled the first switch unit 31 and second and cutChange unit 32 and switch to respectively and the first gear 31a and the third gear 32a of the first checkout equipment 21 conductings,, state as shown in Figure 2 a;
When only having the state of the second checkout equipment 22 to be in the first checkout equipment 21 and the second checkout equipment 22When normal, logical block 33 can control the first switch unit 31 and the second switch unit 32 switches respectivelyTo with the second gear 31b and the fourth speed position 32b of the second checkout equipment 22 conductings, that is, as shown in Figure 2 bState.
Refer to Fig. 3, for the path switching device 30 shown in Fig. 1, can adopt following modeBe achieved:
