Definitions

  • the present invention belongs to the technical field of washing machine, and more particularly to a method for washing machine failure detection and processing.
  • Only the door open/closed status signal is considered in processing in the traditional washing machine detection program.
  • two IO ports are used and the input ports receiving the signals are scanned and read every 10ms; if the signal is not changed in 100 ms continuously, the result by logic operation of NAND of the two IO ports output is being assigned to a buffer register. If the door open signal is detected by at least one of the IO port, the door is regarded in an open state and then the display chip and the power controller are in communication. If the display chip receives the signal indicating the door is opened or the communication with the power controller is failed longer than 3 seconds by means of CRC8 (Cyclic Redundancy Check 8-bit), the motor of the washing machine is being stopped.
  • CRC8 Cyclic Redundancy Check 8-bit
  • EP 1 186 695 is considered to be prior art and discloses a remote control system for a laundry appliance including a remote control device externally accessible via a communication network, the remote control device including a data base storing coping information used to cope with an abnormal condition occurring during operation of the laundry appliance, for every type of the laundry appliance, and a laundry appliance control device connected via the communication network to the remote control device so as to receive the coping information corresponding to the abnormal condition via the communication network from the remote control device when the abnormal condition has occurred in the laundry appliance.
  • the present invention is implemented by the following technical solution.
  • a method for detecting and processing washing machine failure comprising:
  • a Program Counter (PC) pointer detection step which includes:
  • step (13) after resetting the system, reading the current water level data from the water-level sensor and comparing the current water level against the preset water level data, if the current water level is higher than the preset water level, ignoring the water supply program and implementing the subsequent program; if the current water level is zero, implementing the spin-dry program.
  • the method includes a zero-crossing interrupt detection step, in which includes:
  • the method includes a fixed cycle interrupt detection step, in which includes: When it is detected that the upper cover of the washing machine is opened while the alarm fails to properly function and/or the procedure for terminating the current running subroutine is not timely executed, the fixed cycle interrupt error occurs, resetting the system.
  • the method includes a analog to digital conversion (DC) fault detection step of the RAM of the SCM (Single Chip Microcomputer), in which includes:
  • the method includes a SCM register error detection step, in which includes:
  • the method includes a ROM detection step, in which includes: calculating the CRC-16 checksum of the area code of ROM, and then comparing the result with the fixed CRC-16 checksum stored in the ROM, if a mismatch found, ROM error occurs and the exception handling is executed.
  • the ROM detection step calculating the CRC16 check value of a 32-bit data extracted from the ROM every time, and the CRC16 check value of all of the ROM areas are produced until the calculation of all of the data in the ROM is completed.
  • the method further includes the step for processing the special function register: periodically assigning set values repeatedly to the configuration registers of the functional modules used in the SCM.
  • the washing machine failure detection processing method of the present invention can prevent internal operation errors caused by the running programs algorithm of washing machine, and also prevent other faulty operation patterns such as water supply exceeded or washing time exceeded, thereby ensuring the safe operation of the washing machine and reducing the possibility of personal injury caused by the washing machine failures.
  • the present invention provides a washing machine failure detection processing method comprising the following steps: A PC pointer detection step, as shown in Fig.1 :
  • the PC pointer value always vectors to the address of the current executed program. If the PC pointer error occurs in runtime, the washing machine may maintain the current operation patterns because of the control failure, leading to errors as washing time exceeded, spin-dry time exceeded, or water supply exceeded. Those faults do not only damage the motor or other components, but also may further result in accidents and risk the safety of user.
  • the PC pointer detection can sense the runtime safety problems and implement proper process to correct, so that the errors as water supply exceeded or idling cased by internal operation algorithm error could be prevented, thereby ensuring the safety operation of washing machine and lower the possibility of personal injury.
  • the present embodiment after resetting the system in the step S13, in order to prevent repeatedly execute the same program, as example filling water, the present embodiment provides further procedures, in which including reading the current water level data from the water-level sensor and comparing the current water level with the preset water level, if the current water level is higher than the preset water level, ignoring the water supply program and implementing the subsequent program; if the current water level is zero, implementing the spin-dry program. Since at least one complete subroutine is executed through the step S11 and step S12, it is assumed that a complete water supply process is performed. If the current water level is zero, there is no need to perform the water supply program or the washing program repeatedly, the direct execution of the spin-dry program could save water and power and also shorten the operation time.
  • the present embodiment also includes a zero-crossing interrupt detection step, in which includes:
  • the electricity power frequency is 50Hz.
  • the external interrupt port of the SCM receives the electricity power signal through extra electricity circuit.
  • the interrupt generated is defined as the zero-crossing interrupt and the normal signal period is 20ms.
  • the comparison result between the signal period of the zero-crossing interrupt and the time set by the SCM timing controller is used in the program to determine whether the timing interrupt or the zero-crossing interrupt is regular. If a zero-crossing interrupt error occurs, the washing machine may be in a running pattern of continuous one-way rotation which is possibly neglect by the users.
  • the zero-crossing interrupt detection step could sense this zero-crossing error timely and execute system resetting to ensure the safety operation.
  • the present embodiment also includes fixed cycle interrupt detection step, in which includes: When it is detected that the upper cover of the washing machine is opened while the alarm fails to properly function and/or the procedure for terminating the current running subroutine is not timely executed, the fixed cycle interrupt error occurs, resetting the system.
  • the fixed cycle interrupt is used to detect sudden situations when the washing machine should be stopped, such as the upper cover of the washing machine is opened in normal operation, and also used to automatically terminate the running of the washing machine and send alarm signal for preventing users from hurting.
  • the occurrence of the fixed cycle interrupt error results in the situation that the alarm fails to properly function while the washing machine is still running regardless the upper cover is opened, which is a potential safety risk for users.
  • the embodiment is to use the fixed cycle interrupt to further ensure the safety of washing machine running.
  • a DC fault detection step of the RAM of the SCM is provided in this embodiment, in which including:
  • the embodiment includes a SCM register error detection step, in which includes:
  • the method further includes a ROM detection step, in which includes: calculating the CRC-16 checksum of the area code of ROM, and then comparing the result with the fixed CRC-16 checksum stored in the ROM, if a mismatch found, ROM error occurs and the exception handling is executed.
  • CRC is an error check code and characterized in that the bit length of the message and the bit length of the validity are selective.
  • the bits representing the input can be encoded by a polynomial selected and the result is appended with, in the receiving end, the same algorithm is executed to ensure the correctness and completeness of data communication.
  • the CRC-8 cannot meet the requirements for distributing the message length of the area code of ROM while the using of CRC-32 is redundant. Therefore, the CRC-16 is preferably selected to according to the requirements of the area code of ROM and the expected distribution of message length. The use of the CRC-16 can prevent errors written in the programs occurring, thereby ensuring the safe operation of washing machine with program correctness.
  • the ROM detection step calculating the CRC16 check value of a 32-bit data extracted from the ROM each time, and the CRC16 check value of the ROM area is produced until calculation with all ROM data completed.
