According to definition of the present invention, the fault type of coordinate multipoint industry control acquisition system is divided into following five classes: node failure, node group fault, link failure, link group fault and whole link failure.Fault for each class has respectively corresponding fault judgment method and tracer technique.
According to the embodiment of the present invention, proposed a kind of coordinate multipoint industry control and gathered fault monitoring system, as shown in Figure 1, described monitoring system comprises industry control collecting unit, industry control transmission unit and CPU (central processing unit); Described industry control collecting unit comprises acquisition node, multichannel industry control collection plate and the Industrial Control Computer that distributes and manage according to coordinate multipoint; Described industry control transmission unit adopts multiplexing switch cascade to form, and comprises top layer switch and bottom switch; CPU (central processing unit) is that a computing machine that performance is high, computing power is strong forms.For guaranteeing the reliable of industry control transmission, the transport module that increases redundancy is arranged on Industrial Control Computer, each Industrial Control Computer all needs to expand redundant transmission module, while guaranteeing that the affiliated normal link of this Industrial Control Computer breaks down, data can be sent to CPU (central processing unit) place by redundant link.
Wherein, on industry control collecting unit, be responsible for image data from industry control collection plate, and carry out pre-service, encapsulation of data, and send to CPU (central processing unit) by Ethernet; In CPU (central processing unit), be responsible for collecting also analytic message, recombination data, and generate exploded view and analysis result; The intelligent fault monitoring that industry control collecting unit is carried out judges, monitors mainly for node and node group two class faults, and this information is sent to CPU (central processing unit); The intelligent fault monitoring that CPU (central processing unit) is carried out is mainly that the fault of different links is judged and monitored, and for all kinds of faults of whole system, staff is pointed out simultaneously.
For the determination methods of all kinds of faults, will describe one by one below.
(1) determination methods of node failure
On certain acquisition node, break down and be divided into two types, a kind of is that connection line between acquisition node and acquisition node group disconnects, now the data in acquisition node group are that (be now equivalent to link opens a way continuous ultimate value, the electric signal collecting is infinite, and changing into digital quantity is the ultimate value of range); Another is the phenomenon that virtual connection appears in acquisition node place, and the data that show as in acquisition node group are that normal data is to the continuous jump of ultimate value.Obtain after the abnormal data of this acquisition node, the acquisition node group that gathers this node data can be delivered to misdata in Industrial Control Computer, Industrial Control Computer carries out pre-service, analysis node fault type, and the information exchange of malfunctioning node is crossed to industry control transmission unit be delivered to CPU (central processing unit).
(2) determination methods of node group fault
When certain acquisition node group breaks down, data in this acquisition node group can not pass to normally and on Industrial Control Computer, do further processing, Industrial Control Computer does not collect this node group data, because each acquisition node group has numbering, therefore Industrial Control Computer can obtain the information of node group, and the information exchange of malfunctioning node group is crossed to industry control transmission unit is delivered to CPU (central processing unit).
(3) determination methods of link failure
When certain link occurs fault, Industrial Control Computer can not send to CPU (central processing unit) by gathering also packaged data message by industry control transmission equipment, shown in Fig. 1, have redundant link, so Industrial Control Computer can send data message by redundant transmission equipment; For CPU (central processing unit), what while there is link failure, receive is that redundant link passes the message information of coming, and by the analysis to data heading, CPU (central processing unit) is judged fault type.
(4) determination methods of link group fault
Link group fault refers on a plurality of links that belong to a switch and breaks down simultaneously.When one group of link occurs fault, all Industrial Control Computers that this group link connects all can not be sent to CPU (central processing unit) by data message by normal link, and the redundant link that at this moment CPU (central processing unit) receives this group Industrial Control Computer transmission passes the message information come.Now, because the quantity by message that redundant link transmits is more, in order to guarantee reliable industry control collection, while there is link group fault, each Industrial Control Computer need to be adjusted industry control acquisition strategies, as reduce sampling rate, implement the measures such as local storage, thereby avoid because of problems such as the caused industry control bust this of redundant link, resource contentions.
(5) determination methods of whole link failures
All link failure refers to that CPU (central processing unit) does not receive any data, and now fault is divided into two types: the one, and whole industry control acquisition system not yet starts, and only CPU (central processing unit) starts, and now in system, without any data, produces; Another kind of situation is that top layer switch place breaks down, no matter adopt normal transmission equipment or redundant transmission equipment, the data message that gathers and encapsulate on Industrial Control Computer all cannot send normally, at this moment, the data of whole system are all deposited on Industrial Control Computer, cause whole measuring system collapse.So, when whole link failures break down, the second situation especially, CPU (central processing unit) is not only sent five-star warning message, and in industry control collecting unit, carry out local datastore, and reduce the sampling rate of data, make as far as possible the extent of damage of data be down to minimum.
