Please join Fig. 5, it is electrically connected schematic diagram for the inside plate of data communication equipment shown in Figure 4.If in this figure, also show the situation that is electrically connected that exists under traditional business plate 13 situations, because the electric connecting mode of business board 13 is the same with tradition, thereby just no longer describe in detail, below set forth difference emphatically: the relevant connection relation of the master control borad of integrated business function with the existing communication device.
First master control borad 11 comprises that first main control module 112 (CPU or exchange chip) and first business module, 111, the first main control modules 112 and first business module 111 are electrically connected (the dotted line tabular form is by being electrically connected that backboard carries out among the figure) by backboard 10; Second master control borad 12 comprises that second main control module 122 (CPU or exchange chip) and second business module, 121, the second main control modules 122 and second business module 121 are electrically connected by backboard 10.In addition, main control module and business module between the different master control borads also are electrically connected, be electrically connected by backboard 10 between first main control module 112 and second business module 121, be electrically connected by backboard 10 between second main control module 122 and first business module 111.
From above-mentioned electric connecting relation as can be known, any one main control module respectively with two master control borads on business module be electrically connected, but need explanation, thisly be electrically connected that might not to represent between main control module and the business module must be path, the possibility that just has path only is in and main can controls business module on the different master control borads together with the main control module of state.So-called main control module is in the main state of use, and just the master control borad at its place is in and mainly uses state, and another master control borad is in standby holding state, and the main control module on it is also corresponding is in holding state.But it is noted that because any one main control module can be controlled two business modules on the master control borad simultaneously the business module that therefore is on the master control borad of stand-by state also is in running order.
For example, suppose that first master control borad 11 is in the main state of using, second master control borad 12 is in stand-by state, so at this moment, first main control module 112, first business module 111 and second business module 121 are all in running order, and above-mentioned two business modules are electrically connected by the backboard 10 and first main control module 112, are subjected to 112 controls of first main control module; If first master control borad 11 breaks down, behind the described communicator generation masterslave switchover, second master control borad 12 is in the master and uses state, and first master control borad 11 becomes stand-by state.At this moment, first business module 111 and second business module 121 are still in running order, but are subjected to 122 controls of second main control module.
This shows, any one main control module all with two master control borads on business module have electric connecting relation, but only be in mainly when using state at it, can control this two business modules.From another angle, each business module all has electric connecting relation with two main control modules, but only is in main master control module controls with state.
Because first master control borad 11 has identical internal structure with second master control borad 12, thereby be example only, highlight the integration mode of business module and master control borad with first master control borad at this.First business module 111 can be directly welded on the main first control plate 11, also can adopt the form of subcard to be installed on the master control borad 11.Need the explanation since first business module 111 not only with this master control borad 11 on first main control module 112 electric connecting relation is arranged, also need to be electrically connected by second main control module 122 on the backboard and second master control borad 12.Therefore, need connector between first business module 111 and the backboard 10, certainly, also need connector between remainder on first master control borad 11 (as first main control module 112) and the backboard 10.Preferably, above-mentioned two kinds of connectors can be arranged at same row (or row), separate each other, help saving the groove bit space of backboard 10 like this.
By the foregoing description as can be seen and since any one main control module all with two master control borads on business module have electric connecting relation, and be in mainly when using state at it, can control this two business modules.Therefore, in the data communication equipment disclosed by the invention, the business module on active and standby two integrated form master control borads can be worked simultaneously, and utilization rate can reach 100%, and obviously the utilization rate than prior art has improved a lot.
Further, owing to divide the main control module and the business module that are on the different master control borads, and the main control module and the business module that are in same master control borad, all be electrically connected, make that integrated business module and traditional separate traffic plate can be in full accord on implementation on the master control borad by backboard.Therefore the specific implementation of whole communicator is more simple.Certainly, be in the main control module and the business module of same master control borad, can also directly be electrically connected by the holding wire on this master control borad.
