Abstract

The utility model relates to an interface card between a digital control system and a flexible manufacturing system. One end is connected with an epigynous machine, and the other end is connected with the digital control system. A digital signal processor of the interface card is compiled to a bus through a buffer, a photocoupler and a transceiver to connect with the epigynous machine. The digital signal processor is connected with the digital control system through full-duplex serial ports. Consequently, the interface card realizes the connection of the digital control system into a real-time network. The epigynous machine is used for centralized management. Real-time communication is realized. Each digital control machine tool can automatically collect the working state of the machine tool in time to pass to the epigynous machine for carry out management. Consequently, the flexible manufacturing system is realized.

Description

The universal distributed numerical control interface card of digital control system
Technical field
The utility model relates to the interface arrangement of a kind of digital control system and flexible manufacturing system, particularly a kind of universal distributed numerical control interface card of digital control system that can significantly improve the service efficiency of digital control system by this interface arrangement.
Background technology
Numerically-controlled machine tool system is in the unit operation pattern mostly at present, can't utilize the advantage of flexible manufacturing system to improve the efficient of digital control system, thereby can't demonstrate fully the advantage of digital control system.The unit of more existing digital control systems networks each other, certain communication capacity can be provided, but generally only has the RS232 communication interface, therefore after these units are networked, also only can realize the transmission up and down of NC program, can not assume unified command of by host computer, can not satisfy the requirement of flexible manufacturing system, otherwise will adopt the method for man-machine interaction to realize the integrated of information.So it is untimely that the information of the unit duty of existing digital control system is transmitted, it is lower to have influence on its crudy and working (machining) efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of universal distributed numerical control interface card of digital control system that significantly improves digital control system crudy and working (machining) efficiency is provided, thereby realize numerically-controlled machine is linked to be a real-time network, manage concentratedly by host computer.
Solution of the present utility model is: the universal distributed numerical control interface card of a kind of digital control system, one termination host computer, one termination digital control system, the digital signal processor that is characterized in interface card is pooled to the bus interface host computer by impact damper, photoelectrical coupler and transceiver, and digital signal processor is assembled the bus interface digital control system by full twoport serial ports.
The utility model provides the DNC system interface unit to connect digital control system and DNC system host, the DNC system interface unit by with the interface of digital control system, digital control system is controlled and data acquisition.The DNC system interface unit passes through field-bus interface, accept the control of autonomous DNC system machine and upload the digital control system status data, by providing and digital control system and DNC system host hardware interface, the DNC system interface card can provide basic-level support for flexible manufacturing system.The employing photoelectrical coupler is realized the electrical equipment isolation between transceiver and the central processing unit, protection control system circuit.
Digital signal processor can adopt the TMS320F2812 chip in the solution of the present utility model, and this chip built-in has 128KwordFlash, the 2.0B standard of ecAN module and two SCI module support CAN buses, and the highest communication rate of support is 1Mbps.
The full duplex serial ports is for being provided with selector switch in the solution of the present utility model, and each selector switch connects 232 interfaces respectively, 485 interfaces and 422 interfaces.
Photoelectrical coupler adopts 6N137 in the solution of the present utility model, to satisfy the electrical response under top efficiency 1Mbps.The power supply of photoelectrical coupler adopts isolated form DC/DC module, to power to transceiver.
Advantage of the present utility model: the digital signal processor of the utility model interface card receives the host computer instruction by photoelectrical coupler to transceiver, and by full twoport serial ports connection digital control system, realization is linked to be real-time network to digital control system, is managed concentratedly by host computer.Correspondingly digital control system can be gathered automatically by the interface card function.Correspondingly make digital control system can gather the lathe self working state automatically by the interface card function, automatically finish processing situation statistics, can the self recording apparatus on time, job sequence working time, main shaft working time, finish the statistics etc. of equipment operation rate, utilization rate, operation ratio, main shaft operation ratio and utilization factor automatically.Also can receive simultaneously the control command of host computer, the flexible manufacturing system that the general NC lathe is formed has the said function of being made of flexible manufacturing system machining center as manufacturing equipment fully.
The utility model can further specify in conjunction with the accompanying drawings.
Fig. 1 is the utility model electrical block diagram,
Wherein: DSP-digital signal processor, G-photoelectrical coupler, TS-transceiver, DC-DC-insulating power supply BF-impact damper, PST-power supply, P-full duplex serial ports, K-selector switch.
Embodiment
The utility model embodiment as shown in the figure, digital signal processor DSP is pooled to the bus interface host computer by impact damper BF, photoelectrical coupler G1, G2 and transceiver TS, realization links to each other with host computer and accepts the input of host computer, and digital signal processor DSP connects digital control system by full duplex serial ports P.The DC-DC power supply is the insulating power supply of photoelectrical coupler, and power ps is the power supply of digital signal processor DSP, and the full duplex serial ports is provided with selector switch K1, K2, each selector switch of K3 is connected in 232 interface P1 respectively, 485 interface P2 and 422 interface P3.And control the corresponding interface is open-minded.Digital signal processor DSP adopts the TMS320F2818 chip, and photoelectrical coupler adopts 6N137, and the DC/DC power supply adopts IB0505LS-W75, and the 232P interface adopts MAX232.
