Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
Communication channel of the present invention each other between standby plate device for switching be exactly with the communication channel backup that solves prior art and two kinds of birth defects that pattern had of manual switching, be implemented in and carry out the communication channel switching between standby each other plate A and plate B automatically, no longer need communication channel backup or manual switching, promptly from the service of connection devices, the communication channel annexation of this equipment and the service of connection devices without any physics change, the just annexation of this equipment self inside that changes, but communication traffic still can normally carry out, only need between standby plate each other external physical communication passage is provided on a certain block of plate such as plate A to satisfy, need not on plate B, to carry out again external physical communication passage backup.
Communication channel of the present invention switches between standby plate each other can save communication interface, and need not the service of connection devices the communication channel backup functionality is arranged, automatically realize, finish communication channel and between standby each other plate A and B, switch, also need not manual intervention, have good real-time performance and economy.
Fig. 1 is the installation drawing that communication channel of the present invention is automaticallying switch between standby plate each other, as shown in Figure 1, communication channel of the present invention is a kind of brand-new device at the device that automaticallyes switch between standby plate each other, wherein select control register 110, hardware control logic 120 and switch controller 130 by programming device (CPLD, realize that complex programmable logic device) reader also can make otherwise and realize.This device is provided with result and two hardware input signals according to CPU to selection control 110: standby plate is active and standby with signal 121 and this plate communication channel on off operating mode 122 each other, divides following two kinds of situations to carry out the switching of communication channel.
Situation 1: by CPU selection control is set and carries out the communication channel gating, following 3 kinds of configurations can be set:
1. gating " this plate switching system＜-〉 this plate communication channel " is shown in Figure 2;
2. gating " this plate switching system＜-〉 backplane interface " is shown in Figure 3;
3. gating " backplane interface＜-〉 this plate communication channel " is shown in Figure 4.
Situation 2: can't help CPU is provided with selection control gating communication channel, is carried out communication channel by table 1 and switches with signal and communication channel on off operating mode are intelligentized according to active and standby by hardware fully:
Table 1
| Activestandby state | This plate communication channel state | The gating relation | |
| 1 | Main using | Logical | This plate switching system＜-this plate communication channel, shown in Figure 2 |
| 2 | Main using | Disconnected | This plate switching system＜-backplane interface, shown in Figure 3 |
| 3 | Standby | -- | Backplane interface＜-this plate communication channel, shown in Figure 4 |
Cpu subsystem is made of CPU, data storage, program storage and network interface chip and other additional device, mainly finishes functions such as being provided with of running software, local control, remote network management and selection control.
Selection control is provided with by cpu subsystem, except being set, switch controller works in software setting passage gating or the automatic control channel gated mode of hardware, also will be when working in software setting passage gated mode when switch controller, the work of control switch controller, guarantee switch unit correct carry out the passage gating.
The state of hardware control logic is determined jointly by the input logic of " this plate activestandby state incoming line " and " this plate communication channel state incoming line ", when switch controller works in the automatic control channel gated mode of hardware, hardware control logic must guarantee that switch controller correctly controls switch unit, finishes the normal gating of passage.
Switch controller is finished the switching controls of switch unit and the mutually normal gating between realization " this plate switching system ", " this plate communication channel " and " backplane interface " according to the setting of selection control and the state of hardware control logic.
For more specifically setting forth communication channel in the principle of automatic switching control equipment between standby plate each other, be the device schematic diagram with Fig. 1, respectively lift an example in two kinds of situation and describe.
When being provided with selection control by CPU, standby each other plate A and plate B carry out the communication channel gating, plate A is the communication channel that the master uses and this plate is connected with, when plate B is standby, plate A gating " this plate switching system＜-〉 this plate communication channel " is set, as shown in Figure 2, plate B gating " backplane interface＜-this plate communication channel ", as shown in Figure 4; When mechanical A of some time becomes communication channel standby and that this plate is connected with, plate B become main with but this plate when not being connected with communication channel is provided with plate A gating " backplane interface＜-〉 this plate communication channel ", as shown in Figure 4, plate B gating " this plate switching system＜-backplane interface ", as shown in Figure 3.
Standby each other plate A and plate B selection control be set carry out the communication channel gating when can't help CPU, switch with signal and the intelligentized communication channel that carries out of communication channel on off operating mode according to active and standby by hardware fully, plate A is the communication channel that the master uses and this plate is connected with, when plate B is standby, the automatic gating of plate A " this plate switching system＜-this plate communication channel ", as shown in Figure 2, the automatic gating of plate B " backplane interface＜-this plate communication channel ", as shown in Figure 4; When mechanical A of some time becomes communication channel standby and that this plate is connected with, plate B become main with but this plate when not being connected with communication channel, the automatic gating of plate A " backplane interface＜-this plate communication channel " as shown in Figure 4, the automatic gating of plate B " this plate switching system＜-backplane interface ", as shown in Figure 3.
The present invention compared with prior art, obtained and to have carried out the progress that communication channel automaticallyes switch each other between standby plate, reached and saved communication interface resource and cost, real-time, intelligent effect, save the requirement of communication channel backup or manual intervention, improved the on-road efficiency and the efficient of whole system.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
