The invention provides the communication failure diagnostic method in a kind of electric equipment, Fig. 1 is implemented according to the present invention first
Communication failure diagnostic method in the electric equipment of example, as shown in figure 1, this method includes steps S102 to step
S108：
Whether step S102, the network node detected in electric equipment there is communication abnormality.
Whether the network node in detection electric equipment, which communication abnormality occurs, includes：Communication from network node is replied
Information is detected；The time of communication reply message to being not detected by network node carries out timing；Judge whether continuously
The communication reply message of network node is not detected by one preset time；And if do not detected in the first preset time continuously
To the communication reply message of network node, it is determined that communication abnormality occurs in network node.
Electric equipment can be air conditioner or refrigerator.By taking air conditioner as an example, the network node in electric equipment can be
Controller or motor driving plate.
In electric equipment, normally communicated between each network node during normal work, come realize the transmission of signal and
The control of order, in order to find existing communication abnormality in electric equipment in time, it is necessary to reply the communication from network node
Information is detected.Such as between master controller and motor driving plate, when master controller sends control letter to motor driving plate
After breath, motor driving plate sends reply message to master controller, if not detecting that motor driving plate is sent out to master controller
The reply message sent, then now start timing.For another example between the two controllers, the first controller is sent out to second controller
Control information is sent, second controller sends reply message to the first controller, if not detecting second controller to the
The reply message that one controller is sent, then now start timing.Because in electric equipment, the communication of network node is not detected by
Reply message is probably caused by having several factors, it is possible to and the communication reply message of the network node has been sent from, but by
The radiation interference of frequency conversion equipment into surrounding environment etc., the transmission of signal of communication are affected or destroyed, signal of communication
Next network node is not communicated to intactly, therefore does not detect the communication reply message of the network node, in this feelings
Under condition, communicate and do not occur exception, also in the time of normal operation, often several seconds excessively between each network node, it is possible to
Communication reply message is detected, if not detecting the communication reply message of the network node once, is just immediately consider that appearance
Communication failure and report an error, then diagnostic result can be caused unreliable, increase is safeguarded and investigation cost, while largely influences
Consumer's Experience, therefore, it is necessary to judge whether not detecting that the communication of network node replies all the time within continuous certain time
Information, if not detecting the communication reply message of network node in the first preset time continuously, it is determined that network node
There is communication abnormality.
For example, between master controller and motor driving plate, when master controller to motor driving plate send control information it
Afterwards, motor driving plate sends reply message to master controller, if not detecting what motor driving plate was sent to master controller
Reply message, then now start timing, so that the first preset time is 3 seconds as an example, if not detecting within continuous 3 seconds that motor drives
The reply message that plate is sent to master controller, it is determined that communication abnormality occurs in motor driving plate network node.For another example at two
Between controller, the first controller have sent control information to second controller, and second controller sends to the first controller and answered
Complex information, if not detecting the reply message that second controller is sent to the first controller, now start timing, with
One preset time is exemplified by 5 seconds, if not detecting within continuous 5 seconds that second controller is believed to the answer that the first controller is sent
Breath, it is determined that communication abnormality occurs in second controller network node.
Step S104, if detecting that communication abnormality occurs in the network node in electric equipment, in interval preset time
Afterwards diagnostic data is sent to network node.
Sending diagnostic data to network node after preset time is spaced includes：There is communication abnormality from determination network node
Start timing；Judge to determine whether the time that communication abnormality occurs in network node reaches the second preset time；If it is determined that network
The time that communication abnormality occurs in node reaches the second preset time, then sends diagnostic data to network node.
Sending diagnostic data to network node after preset time is spaced includes：At interval of a preset time to network section
Point sends a diagnostic data；Whether detection network node has data to reply after diagnostic data is received includes：Judge sending out
Send whether the diagnostic data of preset times receives data answer afterwards, wherein, if sending the diagnostic data of preset times
Data answer is not received afterwards, it is determined that communication failure occurs in network node.
Due in electric equipment, some exceptions are can be with self-healing, such as the network section of some application program controllings
Point, may during program updating or reconnect can self- recoverage, can in order to further improve diagnostic result
By property, it is necessary to by diagnostic data come judge the network node in electric equipment whether failure, detecting in electric equipment
After communication abnormality occurs in network node, diagnostic data is sent to network node again after certain interval of time, institute's interlude is used
In the communication abnormality self- recoverage for waiting network node, that is, the timing since determining that communication abnormality occurs in network node, judge
Determine whether the time that communication abnormality occurs in network node reaches the second preset time, if it is determined that it is different that communication occurs in network node
The normal time reaches the second preset time, illustrates that communication abnormality does not have self- recoverage, then sends diagnostic data to network node.
Alternatively, the diagnostic data sent to network node whether there is communication failure for diagnostic network node.With
Two preset times be 10 seconds exemplified by, in electric equipment, if detect that communication abnormality occurs in the network node in equipment, such as
Between master controller and motor driving plate, after master controller sends control information to motor driving plate, motor driving plate
Reply message is sent to master controller, if not detecting within continuous 3 seconds that motor driving plate is believed to the answer that master controller is sent
Breath, it is determined that communication abnormality occurs in motor driving plate network node, after it's 10 seconds pasts timing determining communication abnormality occur
Diagnostic data is sent to the motor driving plate again, wherein, diagnostic data includes but is not limited to the abnormal position of deagnostic communication, communication
The time that abnormal type and communication abnormality occur.
Preferably, diagnostic data sends multiple, the network section for exceptional communication occur to confirm diagnostic data to be successfully sent to
Point.
Whether step S106, detection network node have data answer after diagnostic data is received.
After detecting that communication abnormality occurs in the network node in electric equipment, to network node after preset time is spaced
Diagnostic data is sent, after this, whether detection network node has data answer after diagnostic data is received.
Alternatively, in order to reduce influence of the radiation interference of the frequency conversion equipment in surrounding environment etc. to diagnostic result, diagnose
Data can be transmitted by multi-signal type, as long as detecting that network node receives after receiving diagnostic data to any one
To diagnostic data carried out data answer, be considered as network node has data answer after diagnostic data is received.
If receiving data answer, it is considered that the network node is not communication failure, for going out in network node
Existing communication abnormality, it may be possible to temporary transient, often reparation easier than communication failure problem, for example, some communication abnormalities can be with
Repaired by refreshing or restarting, recover normal by selfreparing as far as possible in this case, to reduce carrying for communication failure
Show number, to improve the reliability of diagnostic result.
Step S108, if be not detected by network node has data answer after diagnostic data is received, it is determined that network
There is communication failure in node.
If after detecting that communication abnormality occurs in the network node in electric equipment, to network after preset time is spaced
Node sends diagnostic data, and after this, whether detection network node has data answer after diagnostic data is received, if do not had
Detect that network node has data answer after diagnostic data is received, it is determined that communication failure occurs in network node.It is preferred that
Ground, a diagnostic data is sent to network node at interval of certain time；Detect network node is after diagnostic data is received
It is no to have data answer.
Preferably, in order to reduce the prompting number of communication failure, the treatment effeciency of communication failure is improved, is being not detected by net
After having data answer after receiving diagnostic data, method also includes network node：The direction of the AB lines of network node is carried out
Exchange；Judge after being exchanged to the direction of the AB lines of network node, it is extensive whether network node communicates in the 3rd preset time
It is multiple normal；If network node communication recovery in the 3rd preset time is normal, it is determined that network node selfreparing；And such as
Fruit network node communicates in the 3rd preset time does not recover normal, it is determined that network node communication failure.
In addition to communicating and breaking down really, if AB lines are reversed, also occur that network node is receiving diagnosis number
The situation of data answer can not be carried out after, and it is relatively common the problem of AB lines are reversed, in order to ensure the reliability service of communication,
Network node is not detected by after having data answer after receiving diagnostic data, in software to the side of the AB lines of network node
To being exchanged, after being exchanged to the direction of AB lines, judge whether network node recovers after the 3rd preset time
Normally.
That is, after detecting that communication abnormality occurs in the network node in electric equipment, to net after preset time is spaced
Network node sends diagnostic data, does not detect that network node has data answer after diagnostic data is received, then to network section
The direction of the AB lines of point is exchanged；So that the 3rd preset time is 1 minute as an example, after 1 minute, whether network node is judged
Communication recovery is normal, if network node communication recovery in 1 minute is normal, it is determined that network node selfreparing, if net
Network node communicated also normal without recovery after one minute, it is determined that network node communication failure.
Exchanged by the direction of the AB lines to network node, a number of communication failure can be repaired, improved
The efficiency of communication failure processing, while the reliability of communication failure diagnosis is also improved, it ensure that communication reliability of operation.
Preferably, it is determined that sending failure message information after communication failure, message information can be sent to presets
User, for example, by short message, either the mode such as application message is sent to user mobile phone or computer to phone, can also be at itself
Shown on display, message information includes malfunction and type, and being judged whether according to malfunction and type can be certainly
Repair.
As can be seen from the above description, the present invention is by detecting whether the network node in electric equipment leads to
Letter is abnormal, if detecting that communication abnormality occurs in the network node in electric equipment, to network section after preset time is spaced
Point sends diagnostic data, and whether detection network node has data answer after diagnostic data is received, if being not detected by network
Node has data answer after diagnostic data is received, it is determined that communication failure occurs in network node, solves in electric equipment
Communication failure diagnosis it is inaccurate the problem of.
Fig. 2 is the communication failure diagnostic method in electric equipment according to a second embodiment of the present invention, as shown in Fig. 2 should
Method includes steps S201 to step S207：
Step S201：Judge communication abnormality whether more than 3 seconds.
In electric equipment, during normal work, real-time Communication for Power is being carried out between each network node, to realize the transmission of signal
With the control of order, in order to find existing communication abnormality in electric equipment in time, it is necessary to answer the communication from network node
Complex information is detected.Such as between master controller and motor driving plate, controlled when master controller is sent to motor driving plate
After information, motor driving plate sends reply message to master controller, if not detecting motor driving plate in certain time
The reply message sent to master controller, then illustrate now to communicate to be likely to occur exception.For another example between the two controllers,
First controller have sent control information to second controller, and second controller sends reply message to the first controller, if
The reply message that second controller is sent to the first controller is not detected, then illustrating now to communicate is likely to occur exception.Cause
It is probably caused by having several factors in electric equipment, to be not detected by the communication reply message of network node, it is possible to should
The communication reply message of network node has been sent from, but by the radiation interference of the frequency conversion equipment in surrounding environment etc., communication
The transmission of signal is affected or destroyed, and signal of communication is not communicated to next network node intactly, therefore does not examine
The communication reply message of the network node is measured, in this case, communication does not occur exception, is gone back between each network node
In the time of normal operation, often several seconds excessively, it is possible to detect communication reply message, it is therefore desirable to wait the communication abnormality to be
It is no to continue the regular hour, such as 3 seconds, if the communication abnormality duration more than 3 seconds, perform step S202, determine network
Node communication abnormality.If the communication reply message of the network node was detected within 3 seconds, then it is assumed that network node does not have
There is communication abnormality, if the duration of communication abnormality is not above 3 seconds, perform step S205, communication recovery is normal.Deng
The time for treating 3 seconds be in order to etc. self- recoverage to be communicated, increase the reliability of diagnostic result, certainly, 3 seconds simply one embodiment,
Time herein can also be other preset times, for example, 5 seconds or 2 minutes, according to specific network node difference
Difference, the communication reply message of network node is not still detected only after more than preset time, just determine network node
There is communication abnormality.
Step S202：Communication abnormality.
Specifically, exemplified by the communication between master controller and motor driving plate, when master controller is sent out to motor driving plate
After sending control information, motor driving plate sends reply message to master controller, if not detecting motor driving plate to master
The reply message that controller is sent, then now start timing, do not detect still motor driving plate to master control if having spent 3 seconds
The reply message that device processed is sent, it is determined that communication abnormality occurs in motor driving plate network node.For another example two controllers it
Between, the first controller have sent control information to second controller, and second controller sends reply message to the first controller, such as
Fruit does not detect the reply message that second controller is sent to the first controller, then now starts timing, if spent 3 seconds according to
So the reply message that second controller is sent to the first controller is not detected, it is determined that second controller network node occurs
Communication abnormality.
Step S203：A frame diagnostic data frame is sent out again.
Due in electric equipment, some exceptions are can be with self-healing, such as the network section of some application program controllings
Point, may during program updating or reconnect can self- recoverage, can in order to further improve diagnostic result
By property, it is necessary to by diagnostic data come judge the network node in electric equipment whether failure.For example, it is determined that in electric equipment
Network node there is communication abnormality after, then to network node a frame diagnostic data frame is sent, for the logical of diagnostic network node
Whether letter breaks down, the diagnostic data in diagnostic data frame i.e. first embodiment in the present embodiment.
Alternatively, in electric equipment, if detect that communication abnormality occurs in the network node in equipment, such as in master control
Between device and motor driving plate processed, after master controller sends control information to motor driving plate, motor driving plate is to master control
Device processed sends reply message, if continuous 3 seconds do not detect the reply message that motor driving plate is sent to master controller, really
Determine motor driving plate network node and communication abnormality occur, at this point it is possible to send a frame diagnostic data to the motor driving plate immediately
Frame, the regular hour can also be waited, such as a frame diagnostic data frame is sent to the motor driving plate again after 10 seconds, wherein,
Diagnostic data frame includes but is not limited to the abnormal position of deagnostic communication, the time of type and the communication abnormality generation of communication abnormality.
Alternatively, diagnostic data frame sends a frame at regular intervals, to confirm that diagnostic data frame is successfully sent to occur
Whether the network node of exceptional communication, after this, detection network node have data answer after diagnostic data frame is received.
Alternatively, in order to reduce influence of the radiation interference of the frequency conversion equipment in surrounding environment etc. to diagnostic result, diagnose
Data frame can be transmitted by multi-signal type, as long as detecting network node after diagnostic data frame is received to any one
The diagnostic data frame that kind receives has carried out data answer, and be considered as network node has data to answer after diagnostic data is received
It is multiple.
Step S204：Judge whether to recover proper communication.
It is determined that network node occurs sending diagnostic data frame to network node after communication abnormality, whether detection network node
There is data answer, if receiving data answer, then it is assumed that the network node recovers proper communication, not communication failure, network
The communication abnormality occurred in node is probably temporary transient, often reparation easier than communication failure problem, for example, some communications are different
It can often be repaired by refreshing or restarting, recover normal by selfreparing as far as possible in this case, to reduce communication event
The prompting number of barrier, to improve the reliability of diagnostic result.
If not detecting that the data of network node reply, illustrate that network node does not recover proper communication, perform step
Rapid S206.
Step S205：Communication recovery is normal.
If after detecting that communication abnormality occurs in the network node in electric equipment, diagnostic data is sent to network node
Whether frame, after this, detection network node have data answer after diagnostic data is received, if detecting that network node exists
There is data answer after receiving diagnostic data, it is determined that network node recovers proper communication.
Step S206：Software inverts to communication.
In order to reduce the prompting number of communication failure, the treatment effeciency of communication failure is improved, if network node is receiving
There is no data answer after to diagnostic data frame, communication is inverted using software, that is, the side of the AB lines to network node
To being exchanged；Judge after being exchanged to the direction of the AB lines of network node, whether communication recovery is normal for network node；If
Communication recovery is normal after network node inverts to communication, it is determined that network node selfreparing；If network node is not extensive
It is multiple normal, it is determined that network node communication failure.
In addition to communicating and breaking down really, if AB lines are reversed, also occur that network node is receiving diagnosis number
The situation of data answer can not be carried out after, and it is relatively common the problem of AB lines are reversed, in order to ensure the reliability service of communication,
Network node is not detected by after having data answer after receiving diagnostic data, in software to the side of the AB lines of network node
To being exchanged, after being exchanged to the direction of AB lines, judge whether network node recovers normal.Preferably, to AB
After the direction of line is exchanged, judge whether network node recovers normal again after spending the regular hour, for example, spending 1 minute again
Judge whether network node recovers normal.
Step S207：Judge whether communication recovers.
After sending diagnostic data frame to network node, if not detecting that the data of network node reply, to network
The direction of the AB lines of node is exchanged, and after 1 minute exchanged to the direction of AB lines, judges whether network node communicates
Recover normal, if network node communication recovers normal, it is determined that network node has been repaired, if network node is after one minute
Communication is also normal without recovery, it is determined that network node communication failure.
Exchanged by the direction of the AB lines to network node, a number of communication failure can be repaired, improved
The efficiency of communication failure processing, while the reliability of communication failure diagnosis is also improved, it ensure that communication reliability of operation.
It should be noted that can be in such as one group of computer executable instructions the flow of accompanying drawing illustrates the step of
Performed in computer system, although also, show logical order in flow charts, in some cases, can be with not
