Description
Technical field
The utility model is a kind of to be provided with multi channel backboard, belongs to communication backplane technology field.
Background technology
Fast development along with informationization technology; And the arrival in Internet of Things epoch, the function that needs communication system to realize is more and more, therefore; In order to adapt to the market fast development; The advantage that the designing institute of backboard type embodies is more and more obvious, and the equipment of the original upgrading of this easy design client one-tenth that less input oneself has also improved client's competitive power simultaneously.
In the product of backboard type, the primary controller module is to come transfer instruction and receive the local function module information and come mutual through expansion bus and each functional module on the expansion backboard through the backboard communication channel.The communication system of this complicacy, accurately assign and the real-time monitoring of information of instruction rely on each functional module place backboard to be realized.This shows that the stability of backboard is the key point of the normal operation of total system.
Traditional parallel channel backboard takies more bonder terminal, and reliability is relatively poor, and the channel total length is limited, the functional module negligible amounts of support, and anti-interference is also relatively poor; Traditional low rate channel backboard, speed is low, can't satisfy multidata high-speed functions module; Existing high-speed serial bus backboard, system design are very complicated, and cost is higher.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: the communication that a kind of communication channel is various, signal terminal is few backboard is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind ofly be provided with multi channel backboard; Be disposed with power supply slot, primary controller slot, high speed communication module slot, High Speed I/O module slot, low speed I/O module slot and address setting device on the backboard from left to right; Backboard adopts high speed serialization channel and low-speed serial channel mixing communication modes; All be connected with the high speed serialization channel between said high speed communication module slot and High Speed I/O module slot and the primary controller slot, be connected with the low-speed serial channel between said low speed I/O module slot and the primary controller slot;
Said high speed serialization channel adopts USB 3.0 full-duplex communications, and said low-speed serial channel adopts the asynchronous CAN bus communication of 1Mbps half-duplex.
The low speed I/O module slot that is provided with between High Speed I on the said backboard/O module slot and the address setting device has five.
The utility model compared with prior art has following beneficial effect:
One, the utility model adopts serial channel communication, and signal terminal is few, and system reliability is high, adopts high, low speed serial communication channel Mixed Design, and the functional module kind of support is many, and dirigibility is strong;
Two, the used components and parts of the utility model backboard are few, and circuit design is simple, and cost is low, adopt passive mode, support the hot plug of each functional module, can conveniently realize on-line maintenance and upgrading;
Three, the utility model adopts passive backplane and differential channel, and it is little that backboard produces radiation, and Electro Magnetic Compatibility is higher.
