Description
Technical field
The present invention relates to the wiring of backboard slot position and the communications fields, and in particular to multi-groove interactively communicates on a kind of backboard
Method and device.
Background technique
Currently, with the development of communication network, the running environment of communication equipment is increasingly complicated, therefore the backboard of communication equipment
Upper slot position is also more and more.Currently, the communication means with slot positions all on backboard are as follows: by 1 signal interaction line respectively with back
All slot positions communication on plate.
But the above method has the following deficiencies:
When slot position on backboard is more, the complex distribution of slot position, different slots bit distribution is in different positions, to 1
Signal interaction line is connect with each slot position, then needing to carry out extremely complex cabling, (such as 1 signal interaction line can wind, is curved
Folding is repeatedly etc.), and then do not only result in that cabling process is comparatively laborious, and electrical characteristic is poor, and 1 signal wire be difficult to meet it is all
The temporal characteristics requirement of slot position information transmission；Such as major trough position, the information of the slave slot position farthest apart from major trough position is adopted
Collection and transmission range are longer, and it is larger that this will lead to away wire delay, so that being difficult to transmit letter according to normal timing from slot position
Breath.
Summary of the invention
In view of the deficiencies in the prior art, present invention solves the technical problem that are as follows: when the slot position on backboard is more,
How while line process is walked in simplification, the electrical characteristic of physical bus is improved, the temporal characteristics for meeting the transmission of slot position information are wanted
It asks.
To achieve the above objectives, multi-groove interactively communicates method, the backboard in this method on backboard provided by the invention
Upper includes 1 major trough position and at least ten from slot position, method includes the following steps:
S1: by major trough position by multiple groups physical bus, connecting with all from slot position, and every group of physical bus and 1 group are from slot position
It corresponds, every group of physical bus is connect with 1 group from each of slot position from slot position, goes to S2；
S2: after major trough position generates clock signal and synchronization pulse, by clock signal and synchronization pulse, by every
One group of physical bus is transmitted to every group from each of slot position from slot position, goes to S3；
S3: major trough position and it is all from slot position according to synchronization pulse and clock signal, after generating respective time slot, major trough
Position and it is all from slot position according to respective time slot, respective slot position information is inserted into the physical bus being attached thereto.
Based on the above technical solution, further include following below scheme before S1: by backboard it is all from slot position according to
Position distribution is grouped, and every group is at least 5 from the quantity of slot position.
Based on the above technical solution, the process of S3 includes: after major trough position generates synchronization pulse, according to clock
Signal generates the time slot of itself, and major trough position information is inserted into every group of physical bus according to the time slot of itself by major trough position；From slot position
After receiving synchronization pulse and clock signal, the time slot of itself is generated according to clock signal, from slot position according to itself time slot
The physical bus being attached thereto will be inserted into from slot position information.
Based on the above technical solution, further comprising the steps of after S3: S4: major trough position and all logical from slot position
Coupled physical bus is crossed, after receiving all slot position information, all slot position information are carried out according to the sequencing of time slot
Storage.
Based on the above technical solution, major trough position described in S4 and all pass through coupled physics from slot position
Bus, the process for receiving all slot position information includes: major trough position by every group of all slot position information of physical bus reception, from slot position
All slot position information are received from the physical bus of slot position group by affiliated.
Based on the above technical solution, every group of physical bus in S1 includes 1 clock data line, 1 synchronous arteries and veins
Rush data line and 1 root information interaction data line.
Based on the above technical solution, major trough position described in S2 by clock data line by clock signal transmission to every
It is a from slot position, synchronization pulse is transmitted to by synchronous pulse data line each from slot position；Major trough position described in S3 and institute
Have from slot position according to respective time slot, respective slot position information is inserted into the interactive data information line being attached thereto.
Multi-groove interactively communicates device on the backboard provided by the invention for realizing the above method, including is provided with 1 master
Slot position and at least 2 groups of backboards from slot position, described 2 groups are at least 10 from the sum of quantity of slot position, and major trough position passes through multiple groups object
