Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
First embodiment of the invention relates to a kind of communication failure detection method, is used for smart machine communication looped network.Comprise the smart machine (IED) under a main control device and the control thereof in the communication looped network, main control device comprises at least two PORT COM, each smart machine comprises at least one PORT COM, each smart machine under the described main control device control is connected in series by its PORT COM, two PORT COM of described main control device connect the PORT COM of two smart machines at two ends respectively, form a communication looped network, as shown in Figure 2.
The idiographic flow that communication failure detects under this looped network as shown in Figure 3.
In step 301, main control device sends wheel by first PORT COM and surveys order, sends to each smart machine that connects on the communication link in proper order along this looped network, and receives the response message that each smart machine returns.If at the appointed time do not receive the response message of all smart machines in the interval, then enter step 302; Perhaps behind the Preset Time interval send the order of wheel side by first PORT COM after, directly enter step 302.
In step 302, main control device sends wheel by second PORT COM and surveys order, sends to each smart machine that connects on the communication link along this looped network backward inspection, and receives the response message that each smart machine returns.By control and adjustment, guarantee that the wheel survey that two PORT COM are carried out can not clash to the time interval.
In step 303, main control device is taken turns the response message of side order and the response message of backward wheel side order in proper order according to this, determines to exist in the communication looped network smart machine or the communication link zone of fault.
Specifically, if in the step 301, main control device is received the response message of order top n smart machine in the looped network, and in the step 302, main control device is received the response message of preceding M the smart machine of backward in the looped network, determine that then the link between this N smart machine and this M smart machine breaks down M+N≤smart machine sum.
If in the step 301, main control device is not received the response message of at least one smart machine in the looped network, this at least one smart machine is discontinuous, and among the described step B, main control device is not received the response message of identical smart machine, then determines at least one smart machine fault of this no answer information.
For example, main control device sends wheel by PORT COM 1 and surveys order among Fig. 2, check the communication state of IED1 in the passage, IED2......IEDn successively, send wheel by PORT COM 2 subsequently and survey order, check the communication state of IEDn......IED2 in the passage, IED1 successively.As by 1 response message of receiving IED1 and IED2 of PORT COM, and do not receive the response message of IED thereafter, and receive that by 2 of PORT COM IED3 reaches the response message of IED thereafter, and do not receive the response message of IED2 and IED1, can judge that then communication line interrupts, and interruptions is between IED2 and IED3.Perhaps, as receiving the response message of all IED except that IED3 by PORT COM 1, and receive the response message of all IED except that IED3 equally, can judge that then IED3 equipment breaks down by PORT COM 2.
In actual applications, main control device can regularly send the order of wheel side by first PORT COM and second PORT COM, detects in the communication looped network whether have fault.
By this mode, main control device can be according to two rightabout testing results, obtain unique corresponding detection result, the zone of breaking down in directly definite looped network, very convenient, need not to investigate possible failure cause one by one, also need not manually investigate, reduced the maintenance cost of smart machine by equipment.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
