Description
Technical field
The utility model relates to a kind of interface control module, particularly relates to a kind of based on magnetic-coupled interface controller.
Background technology
Current existing Ethernet turns RS-232 communication interface controller, be mostly Ethernet turn single channel RS-232 interface or turn two-way RS-232 interface, and institute has RS-232 interface and does not usually possess isolation characteristic, even if there is isolation characteristic, is also generally that the mode of Phototube Coupling realizes.Because industry spot has the data much with RS-232 interface instrument to need to gather usually, if use Ethernet to turn single channel or two-way RS-232 interface controller, need multiple equipment, increase equipment investment; Simultaneously because industry spot interference source is many, the feature that interference magnitude is large, does not have electrical isolation RS-232 interface to be easy to interfering signal to introduce device interior, thus causes equipment cisco unity malfunction.
Utility model content
Technique effect of the present utility model can overcome above-mentioned defect, and provide a kind of based on magnetic coupling isolated form ethernet interface controller, it realizes the transition of communications of Ethernet to 5 road RS-232 interfaces.
For achieving the above object, the utility model adopts following technical scheme: it comprises ethernet communication module, primary processor, RS-232 communication module, magnetic coupling isolation module, power module, communicate between primary processor with ethernet communication module, primary processor is communicated with magnetic coupling isolation module by RS-232 communication module, magnetic coupling isolation module connects ancillary equipment, and power module is electrically connected with ethernet communication module, primary processor, RS-232 communication module, magnetic coupling isolation module respectively.
Preferably, described RS-232 communication module arranges 5 tunnels.Because module support reaches 5 road Asynchronous Serial Interfaces, different interfaces is determined in order to correctly distribute, each serial line interface has an independent port numbers, when changing mutually between Ethernet protocol and asynchronous serial communication protocol, by primary processor, information discriminating is classified, the port numbers that comformed information is corresponding, then determine to realize changing between which serial line interface and Ethernet according to port numbers.
Preferably, described primary processor adopts LM4F232 model.This isolated form Ethernet turns 5 road RS-232 communication interface controllers, with up-to-date 32 level controllers of American TI (TIX) for control core, realize the transition of communications of Ethernet to 5 road RS-232 interfaces, adopt magnetic coupling technology to realize 5 road RS-232 electrical isolation simultaneously.Reduce the input cost of the data acquisition equipment of industry spot, improve the communication reliability of system, add the stability of equipment work.
By SPI interface communication between primary processor and ethernet communication module.
Described ethernet communication model calling data center server.
Because the electric parameter of external equipment is complicated, directly by serial ports and external device communication, very likely cause the electric parameter of inside modules abnormal, therefore module asynchronous serial port arranges photoelectric isolation module, realizes the electrical isolation of the external communication interface of 5 road Asynchronous Serial Interfaces.Support the isolated form RS-232 interface on nearly 5 tunnels, reduce the quantity of industrial field data collecting device, thus reduce cost input, simultaneously owing to adopting magnetic coupling isolation technology, stop the large interference of industry spot and noise enters system by RS-232 interface, improve the stability of system works.
Accompanying drawing explanation
Fig. 1 is modular structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, of the present utility model based on magnetic coupling isolated form ethernet interface controller, comprise data center server, ethernet communication module, primary processor, RS-232 communication module, magnetic coupling isolation module, power module, by ethernet communication module communication between data center server and primary processor, primary processor is communicated with magnetic coupling isolation module by RS-232 communication module, magnetic coupling isolation module connects ancillary equipment, power module respectively with data center server, ethernet communication module, primary processor, RS-232 communication module, magnetic coupling isolation module is electrically connected.
Described primary processor adopts LM4F232 model, and by SPI interface communication between primary processor and ethernet communication module, described RS-232 communication module arranges 5 tunnels.
Primary processor is communicated with ethernet controller by SPI interface, and the ethernet communication function of realization and data center server, communication protocol is ICP/IP protocol.Data center server is needing to send to the Command encapsulate of instrument of industry spot in ICP/IP protocol, and with specific tcp port number, primary processor is sent to by Ethernet, primary processor parses the order that data center server sends from the data received, and order is sent to and receives tcp port number RS-232 interface one to one, realize the transmission of data center server to the teleinstruction of instrument.After the instrument of industry spot receives orders, the data needing to return to data center server are sent to primary processor by RS-232 interface, primary processor is again the data received, be packaged into ICP/IP protocol, return to data center server by Ethernet, thus achieve with EPA be core data center server directly and the two-way reliable data communication of the RS-232 interface instrument of industry spot.
