Abstract
The present invention provides a field bus communication failure recording device which is connected with a field bus system in a slave station mode. The present invention comprises an address encoder, a failure recording device and an output device, wherein the output device is respectively connected with the address encoder and the failure recording device; the address encoder is provided with a receiving encoder and a sending encoder, wherein the receiving encoder is a full address encoder for receiving communication signals and only receives communication contents which are received and sent out by all the addresses in the field bus system; the sending encoder is provided with a sending communication address shield so that the sending encoder can not send out any information by using the addresses of other slave stations. Besides, the failure recording device can record the failure associated information of slave stations or main stations which generate communication failures; the output device is used for outputting failure records.
Description
Technical field
The present invention relates to the field bus communication field, particularly relate to a kind of field bus communication failure recording device.
Background technology
In the computer industry communication field, field bus communication has stronger technical advantage.But the electrical interference of industrial environment is the problem of aspects such as electromagnetic compatibility, often causes Communications failure, communicating interrupt.The problem that simultaneously different separately industrial environments brings for computer control and communication system also is various.What the technician was puzzled the most is the property a crossed fault that occurs at random, is difficult to catch, and also just is difficult to analyze, and takes some countermeasures.
In sum, need a kind ofly come captured information towards the field bus communication failure recording device.
Summary of the invention
The objective of the invention is to: propose a kind ofly to catch relevant information towards the field bus communication failure recording device.
Technical scheme of the present invention is: design a field bus communication failure recording device, can be connected in field bus system in the mode of substation, comprise address scrambler, the device of record trouble and output unit, wherein said output unit links to each other with the device of described address scrambler and described record trouble respectively, the method of its address interlock circuit and traditional substation is different, described address scrambler has the received code device and sends scrambler, described received code device is a full address scrambler that receives communication signal, receive only the Content of communciation that whole addresses receive and send in the system, described transmission scrambler; Have one and send address shielding device, make it can not send any information with the address of other substations; The device of described record trouble can write down the substation of communication failure or the fault relevant information of main website; Described output unit is used to export failure logging.
According to one embodiment of the present of invention: when the field bus communication failure recording device need give the correct time on main control computer by described field bus communication system network, described output unit just directly reports failure logging with communication modes, and at this moment described transmission address scrambler is that described output unit produces a unique transmission address.
According to one embodiment of the present of invention: but described output unit is the electronic recording equipment of an off line, and optionally device is similar devices such as " flash disk " mobile electron hard disk with UBS interface, floppy disk, hard disk, portable hard drive, compressible floppy disk ZIP dish, magnetic recording system.
According to one embodiment of the present of invention: described field bus communication failure recording device also has an onsite alarming device.
The invention has the advantages that the field bus communication failure recording device catches the communication failure relevant information.And can have online directly report and but the off-line of off line reports the function of analysis through field bus system, can fully catch accidental and communication failure that take place frequently.
Embodiment
Further specify technical scheme of the present invention below in conjunction with embodiment.

Embodiment 2: in this embodiment, when the field bus communication failure recording device need come to give the correct time on main control computer by the field bus communication system network, output unit just directly reports failure logging with communication modes.At this moment sending address scrambler is that output unit produces a unique address scrambler transmission address, promptly needs the transmission address when industrial control system reports Content of communciation.
Embodiment 3: in an embodiment, but output unit is the electronic recording equipment of an off line, and optionally device is similar devices such as " flash disk " mobile electron hard disk with UBS interface, floppy disk, hard disk, portable hard drive, compressible floppy disk ZIP dish, magnetic recording system.
Embodiment 4: in this embodiment, the field bus communication failure recording device also has an onsite alarming device.
Embodiment described herein can be made up under situation about not contradicting each other, and finishes the invention task better.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present invention; those skilled in the art can be under the situation that does not break away from invention thought of the present invention; the foregoing description is made various modifications or variation; thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
Claims (4)
