The utility model is used for numerical control systems, and discloses a bus substation communication circuit board for a numerical control system. The circuit board is provided with bus physical-layer interface chips, a field-programmable gate array chip, and a processor chip. The number of the bus physical-layer interface chips is two, and the two bus physical-layer interface chips are in bidirectional connection. The two bus physical-layer interface chips are respectively connected with the field-programmable gate array chip through an RMII interface, and the field-programmable gate array chip is in bidirectional connection with the processor chip. According to the utility model, hardware, which achieves the ZEXBUS bus substation communication, is integrated into one independent communication module, and there is no need of processing any content related to a ZEXBUS bus protocol physical layer or an MAC layer, and an upper layer. The related processing are all achieved by the communication module, thereby simplifying the design of a substation, reducing the design difficulty, and reducing the cost of manufacture and maintenance of the substation.

Description

A kind of bus substation communicating circuit plate for digital control system
Technical field
The utility model relates to digital control system, has related in particular to a kind of bus substation communicating circuit plate for digital control system.
Background technology
In kinetic control system, network substation often has different functions, such as the additional panels substation in Control System of NC Machine, lathe input and output substation, servo-driver substation etc., and each substation needs to design ZEXBUS bus interface part.The bus interface partial function of each substation is similar, but needs again independent design, and therefore its design and maintenance cost are all higher, and versatility is also poor, has affected to a certain extent using and promoting of bus.
Summary of the invention
The utility model is all higher for design and maintenance cost in prior art, and also poor shortcoming of versatility provides a kind of reduction to design and the bus substation communicating circuit plate for digital control system of maintenance cost.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of bus substation communicating circuit plate for digital control system, bus substation communicating circuit plate is provided with bus physical layer interface chip, field programmable gate array chip and processor chips, bus physical layer interface chip is two, the two-way connection of double bus physical layer interface chip chamber, double bus physical layer interface chip is all connected with field programmable gate array chip by RMII interface, and field programmable gate array chip is connected with processor chips are two-way.In field programmable gate array chip, there is ZEXBUS bus MAC layer and process the software that relevant process software is relevant with user interface process; In processor chips, there is ZEXBUS bus upper-layer protocol and process relevant software; Bus physical layer interface chip is responsible for processing ethernet physical layer signal, input/output signal is encoded and processed, it uses RMII interface and field programmable gate array chip to communicate, after physical layer signal on ethernet line is processed, deliver to field programmable gate array chip and process, after the data processing of sending here for field programmable gate array chip, become ethernet physical layer signal and be sent on circuit simultaneously.Field programmable gate array chip is realized the MAC layer related protocol of ZEXBUS bus, because the mac-layer protocol of ZEXBUS bus is different from the mac-layer protocol of general network interface card, therefore needs to use field programmable gate array chip to process.Meanwhile, field programmable gate array chip is also realized user interface, i.e. the interface relevant to final function, as in the function of the output output function of additional panels, lathe input and output, servo driving with the functions such as communicating by letter of digital signal processor (DSP).Processor chips realize the upper-layer protocol of ZEXBUS bus, deliver to field programmable gate array chip, for user after transceiving data is processed again.ZEXBUS bus, based on ethernet physical layer, has proprietary mac-layer protocol and upper-layer protocol, can realize 50 delicately with interior communication cycle, and network substation can reach more than 32.
As preferably, left part and the right part of bus substation communicating circuit plate are equipped with user interface socket, and user interface socket is connected with field programmable gate array chip is two-way.
As preferably, bus physical layer interface chip is connected with ethernet line is two-way.
As preferably, field programmable gate array comprises configurable logic module, output load module and interconnector.
The utility model is by the hardware integration to of realizing ZEXBUS bus substation communication independently in communication module, ZEXBUS bus substation based on this Communication Module Design, do not need to process any and ZEXBUS bus protocol Physical layer or MAC layer, any content of upper-layer protocol, relevant treatment is all realized by this communication module, and leave the interface that can accept other part controls of substation, additional panels substation so, lathe input and output substation, servo-driver substation etc. can be used same communication module, thereby simplify the design of substation, reducing design difficulty and substation manufactures, maintenance cost, therefore, for the entity or individual that does not possess abundant ZEXBUS bus substation development Experience, use this module to set up cost of development and the efficiency of ZEXBUS bus substation higher, it is more convenient to realize, and more reliable and more stable.
