Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is module machine system architecture figure of the invention.
Fig. 2 is module machine system failure processing method flow chart of the invention.
Specific embodiment
The principle and embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows system module figure of the invention, which is made of multiple module machines, and each module machine can be independent
Operation, dereliction takes second place point between modules machine, can transmit status information between each module machine mutually and completion is cooperateed with to give
Operational objective.
Fig. 2 shows the flow charts of troubleshooting of the present invention, have specifically included breakdown judge, troubleshooting and failure and have reported
Three aspects.
During system operation, the operating status of modules machine cycle detection itself and transmission, while module machine
The operating status of itself is stored, the operating status of storage can judge this mould after the fault detection of next cycle
Block machine fault-free is discharged again.
After the storage of completion status data, module machine first determines whether itself with other module machines communication failure occurs, when
When having the confirmation of module machine and other module machines not to communicate, it is also possible to the discovery of other module machines and is not communicated with some module machine
When, the operating load information of itself can not be sent to other normal module machines by the module machine that communication failure has occurred, then
Need the operational objective and other normal currently running state energy of module machine of other normal module machine Conjoint Analysis systems
What kind of operational effect enough reached, i.e., the operating status of normal module machine joint given operational objective and each normal module machine is come
Calculate the operating load that should share.
If other failures other than communication failure, as temperature sensing package failure (i.e. temperature sensor fault), compressor fault,
(protection belongs to the prior art, and existing auxiliary hot apparatus overheat Shi Douhui has protection mechanism, and air-conditioning system can for auxiliary blocking under warming protection
To detect protection signal that auxiliary hot equipment is triggered) etc..When judging whether the duration of other failures is more than or equal to default
Between, if so, there are other failures in determination module machine, if it is not, being then normal by other fault verification.For example, continuous 3 seconds detect
To other failures, then the presence of other failures is determined, which sends the operating load information of itself to by communication network
Other module machines, reduce the consumption of other module machines computing system operational objective and other existing operational effects of normal mode block when
Between, generally than there is communication failure when calculating speed improve.When fault verification is normal by module machine, time of failure is counted
Number, the report of user when the number of failure reaches preset times.In specific application if repeated detection was to other of discontented 3 seconds
Failure, then illustrating the module machine itself, there are the risks of failure, need timely report of user to issue corresponding warning and remind user
Timely maintenance and inspection, and send self-operating information on load and give other normal module machines, allow other normal module machines to share this
Operating load；If can be confirmed system temporarily without there is any event without other failures within repeated detection to 3 seconds
Barrier, whole system keep operating normally.
When there is the failure of module machine in system (communication failure or other failures), other normal module machines calculate because
The operating load that the needs that the failure generates solve needs to calculate each normal module machine should increase how much fortune in other words
The operational objective that row load could maintain system given, in the present embodiment, the part operation that each normal module machine is shared are negative
Lotus be the operating load that needs to solve caused by failure divided by the quantity of normal module machine obtain share out equally after operation
Load.
After by calculating, normal module machine judges whether that the operating load shared can be undertaken, if can be to mention
Operating load is risen, system is made to reach original operational objective again.Divided if each normal module machine finds that itself can not undertake
When the operating load at booth, report of user issues the user with the warning for being unable to complete operational objective, and each of system is normal
Module machine is exported with maximum operating load, specifically, reducing system fortune to greatest extent with the output of maximum safe operation load
Gap between row effect and given operational objective.And issuing the user with for systems stay up to standard can not alert, and remind user
Close or modify in time operational objective.
After system improving operating load, whether system detection communication failure restores.If communication failure does not restore,
Then there is the module machine of communication failure to reporting of user, and closes the module machine of communication failure；If communication failure has restored,
Then restore original operating status, retains the module machine and the record of communication failure but not report of user occurred.
Detect communication recovery followed by detects the module machine for other failures occurred, if detecting that failure does not have still
There is recovery, then to reporting of user malfunctioning module machine and closing fault module machine；If detecting that failure has been restored, system restores former
The operating status come retains the module machine and the record of failure but not report of user occurred, and subsequent system keeps operating normally simultaneously
Into the detection in next period.
In the present invention, system report of user is especially by sending information to the addressable terminal of user, such as sends letter
It ceases to the display screen etc. of user.Other than module machine system is by the way of sharing come influence caused by handling failure,
He can also attempt by the way of sharing come handling failure air-conditioning system.The operational objective of signified system of the invention is specific
It can be the total refrigerating capacity of system either heating capacity.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
