Embodiment one, the present embodiment propose a kind of washing machine fault detection processing method, comprising the following steps:
PC pointer detecting step, as shown in Figure 1:
S11, each operational process of washing machine is detected respectively, the corresponding sub- journey of each operational process of washing machine
Sequence is initially respectively logic register assignment in each subprogram activation, and the operational process includes at least the injecting process, washed
Journey, dehydration；
Whether S12, the current value for detecting logic register respectively after each subprogram activation are identical as assignment, if working as
Preceding value is different from assignment, then is judged as PC pointer failure, and which fortune that current failure comes across washing machine recorded according to assignment
Row process；
S13, when being judged as PC pointer failure, waiting time t1, and continue to test logic register current value whether
It is identical as assignment, if they are the same, then the subprogram is continued to execute, system reset is otherwise executed.
The value of PC pointer always points at the address of the operating point of present procedure, in washing machine operational process, if program occurs
PC pointer is abnormal, control failure, and a certain operational process, which can occur, for washing machine persistently carries out, and such as washs more than；Or dehydration is more than；
Or it intakes phenomena such as more than.Above-mentioned failure gently then damages motor or other hardware, and severe one causes an accident, and threatens and uses
Family personal safety.This washing machine fault detection processing method is detected by PC pointer, can detect operational safety problem in time,
And corresponding processing is taken, washing machine algorithm internal operation mistake is prevented, more than, the empty barrel state into water is caused to be washed always
Equal error runnings mode occurs, and has ensured the safe operation of washing machine, reduces and brings injury to the person because of washing machine failure
Possibility.
In the present embodiment, in the step S13, after the execution system reset, the journey that had executed in order to prevent
Sequence repeats, and if the injecting process is just not necessarily to fill the water again if being already filled with, prevents from further resulting in new failure generation,
Therefore, in the present embodiment by read water level sensor detection current level value, by current level value and setting water level value into
Row compares, if current level value is greater than or equal to setting water level value, skips the injecting process, executes next mistake of the injecting process
Journey, if in the washing condition and current level value is zero, executing dehydration.Due to undergoing step S11 and step S12, until
A complete subprogram is run less, therefore, it is possible to judge that the injecting process has at least been executed, if current level value is zero, just
It no longer needs to fill the water again, wash, directly execution dehydration, avoid the waste of water resource and electric energy, and save and wash
Wash the time.
Further include that zero passage interrupts detecting step as a preferred embodiment, in the present embodiment:
S21, setting T1 zero passage interrupt cycle, practical T zero passage interrupt cycle of detection load signal on motor；
S22, compare T whether in [T1- △ t1, T1+ △ t1] interval range, if so, it is judged as that zero passage is interrupted normally,
Otherwise, it is judged as zero passage abnormal interruption；
S23, when being judged as zero passage abnormal interruption, then execute system reset.
City's frequency power frequency is 50Hz, and city's electric signal is guided on single-chip microcontroller external interrupt mouth using hardware circuit, in this
Disconnected is that zero passage is interrupted, and the signal period is normally 20ms, when being exactly the timer using this signal period and single-chip microcontroller in program
Between be compared, to judge that it is whether normal that timer interruption or zero passage are interrupted.If zero passage, which is interrupted, exception occurs, it is embodied in washing machine
Operation aspect may be lasting rotating forward or lasting reversion, it is not easy to be found in time by user, the washing machine failure of the present embodiment
Detection processing method can detect zero passage abnormal interruption in time, and control execution system reset, protect washing machine operational safety.

When detecting that washing machine opens upper cover in the process of running, it is not carried out alarm and/or stops current operation
The step of program, is then judged as Interruption exception, executes system reset.
In washing machine operational process, Interruption opens washing machine top case complete machine for detecting when washing machine operates normally
When appearance is uncapped or other are not suitable for the emergency situations that washing machine continues to run, it can control and shut down in time, and alarm,
To prevent from damaging user, if Interruption goes wrong, will lead to as opened upper cover not when washing machine operates normally
It alarms and does not shut down, there are security risks.The present embodiment further ensures that washing machine is run by detecting Interruption
Safety.
If there are DC failures by single-chip microcontroller RAM, causes single-chip microcontroller write-in different from the value read, cannot be held according to setting program
Row, therefore it, further includes the DC failure detection steps of single-chip microcontroller RAM in the present embodiment that washing machine, which can not work normally:
Chessboard method cycle detection periodically is used to all addresses single-chip microcontroller RAM；
The numerical value of test address is first Saved and Closed interruption before detection, is to examine the numerical value preservation of test address
After survey, it, by not closing interruption, is to detect in order to prevent that still recovery routine is operated normally according to the numerical value of original write-in
When generate interruption, the test value write into RAM is handled as normal value in interrupt routine, first to first test
Location assignment 0x55 perhaps one of value in 0xaa while to other one in next test address assignment 0x55 or 0xaa
A value, then respectively by reading data in two test addresses, and be compared with the data of write-in, if differing, then it is assumed that RAM is asked
Topic carries out abnormality processing；If equal, other test addresses are detected in the same way, until by all test ground
Location detection finishes.Wherein, 0x55 write-in numerical value i.e.: 01010101,0xaa write-in numerical value are as follows: 10101010, the present embodiment
By the way that 0x55 and 0xaa is assigned to two adjacent address rams simultaneously respectively, the two is distinguished using the difference of numerical value, is prevented
Only two addresses are assigned same value and judge incorrectly, realize while detecting to two addresses, improve detection
Efficiency.After all address detecteds are finished, it is also necessary to which since first address, re-writing the address does not have
Another value of write-in, for example, illustrate can only there is part position to be written with 1 if first address assignment 0x55 first, because
This, second time assignment when, answers the position of assignment 0xaa namely first pass assignment 0 to be assigned a value of 1 at second time, and realizing can will
It is effectively detected all positions.
Further in the present embodiment, further include to single-chip microcontroller register failure detection steps:
Chessboard method cycle detection periodically is used to all registers；
It is read again after one of value that each register is written in 0x55 or 0xaa one by one, and compares the value of reading
It is whether consistent with the value of write-in, it is read again after another value being then written in 0x55 or 0xaa, and compare the value of reading
It is whether consistent with the value of write-in, when only comparison result is consistent twice, obtain the normal conclusion of the register, otherwise the deposit
Utensil is faulty, reports register failure, executes system reset step.The present embodiment is by respectively examining each register
It surveys, and takes the mode for being respectively written into 0x55 and 0xaa numerical value, realizing can effectively be detected all positions of register.
Further include the steps that detecting ROM, calculate ROM area code CRC-16 verification and, and will calculate in structure and ROM
The CRC-16 of the fixation of storage is verified and is carried out compared with if inconsistent, then it is assumed that ROM is problematic, carries out abnormality processing.CRC is one
Kind error check code, it is characterized in that the length of information field and check field can be arbitrarily selected.Data can be carried out multinomial
Formula calculates, and obtained result is attached to behind frame, and receiving device also executes similar algorithm, to guarantee data transmission just
True property and integrality.In the present embodiment, since ROM area code length is longer, 8 CRC are unable to satisfy its length needs, and 32
CRC will cause calculating waste again, therefore 16 CRC checks and detection are preferably used in the present embodiment to ROM area code,
That is CRC-16, CRC-16 verification and detection can prevent the program being written into the area ROM from mistake occur, and washing machine is only being protected
Normal under the premise of card program is correct, safety operation.
Specifically in the present embodiment, in the step of detecting to ROM, the data of 32 bytes in ROM is taken to carry out CRC- every time
16 are calculated a check value, until all data in ROM have been calculated, obtain the CRC-16 check value in all areas ROM.
The washing machine fault detection processing method of the present embodiment further includes the steps that special function register processing: the period
Property the functional module that single-chip microcontroller is used configuration register according to setting value carry out repeated assignment of values.Specified register is generally controlled
The input of single-chip microcontroller processed, delivery outlet, there is mistake in the process of running in input, delivery outlet defined in program in order to prevent, such as
Input port becomes delivery outlet or delivery outlet becomes input port, will lead to and mistake occurs, and therefore, this method is not by stopping to assign
Even there is mistake in pilot process in the mode of value, can in time accordingly by the repeated assignment of values right value of this method
Correction comes, and does not influence the safe operation of program.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
