Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the present invention provides a method for automatically recovering an operation of a device, which specifically includes the steps of: the method comprises the following steps that the hot water machine is installed and debugged for the first time, an automatic recovery system mode is started after normal operation of the hot water machine is debugged, parameter setting and system parameters corresponding to the parameter setting in the operation of the hot water machine are detected, and the parameter setting and the system parameters in a preset time period of normal operation are backed up; when the system of the equipment is in an abnormal state, the current parameter setting of the system is restored to the parameter setting backed up in the last preset time period, if a user carelessly enters a test mode, the frequency of a compressor in the parameter setting is adjusted to be large at the moment of starting up, so that more pipeline gas is gathered, the unit is likely to have repeated high-voltage protection, the parameter setting of the unit for starting up the unit to automatically restore the last normal work is reduced, and the unit is enabled to automatically restore the normal work.
In a particular embodiment, the abnormal condition includes a high pressure protection of the water heater.
And after the reduction parameters are set, judging whether the abnormal times of the system in a second preset time period are greater than the preset times, if so, indicating that the system fails, stopping the system from running, and starting a fault removal program.
The troubleshooting procedure includes the steps of: comparing the system parameters in the abnormal state with the system parameters backed up in the previous preset time period, finding out abnormal parameters with the deviation larger than the corresponding preset deviation, determining an abnormal module according to the module corresponding to the abnormal parameters, comparing the abnormal module with the corresponding abnormal parameters with a preset fault comparison table, judging whether the fault caused by the abnormal module is a maskable fault, and if so, continuing to operate the shielding abnormal module.
Maskable faults include: and when the fault is the fault which can be indirectly shielded, the associated system parameters corresponding to the abnormal parameters are found out according to the fault comparison table, and the normal system parameters of the abnormal parameters are calculated and recorded according to the associated system parameters.
The preset fault comparison table stores the classification and damage grade of various module faults, for example, the manual operator can directly shield the faults, the water consumption of a user can be ensured to be normal due to the damage of the manual operator, the unit cannot receive data (system parameters) returned by the manual operator in a fixed time period, so that the parameters are abnormal, but other parameter settings of the system are normal with the system parameters, and the manual operator can be directly shielded after the faults occur. For example, the water outlet temperature sensing bulb is abnormal and can indirectly shield faults, the water outlet temperature is required to be known by a user, but the system parameters recorded by the water outlet temperature sensing bulb are abnormal when the water outlet temperature sensing bulb is abnormal, the system parameters of the module related to the water outlet temperature sensing bulb are recorded in the preset fault comparison table, the normal system parameters of the abnormal module can be calculated according to the normal system parameters of the related module and displayed to the user, and if the module related to the water outlet temperature sensing bulb is an exhaust temperature sensing bulb, a water tank temperature sensing bulb and a water inlet temperature sensing bulb, the normal system parameters of the abnormal module can be calculated and displayed.
The specific mode of the abnormal shielding module is as follows: the communication between the system and the abnormal module is shielded, and the fault is prompted by alarming, so that a user can timely know that the module fault is processed as early as possible.
If the fault is not maskable fault, the corresponding abnormal module and abnormal parameters cannot be found from the preset fault comparison table, or the preset safety level of the abnormal module is high, if the direct operation causes serious fault or endangers the safety of a user, the system directly stops operating and gives an alarm to prompt the fault, so that the loss of the user is reduced.
The alarm prompting mode comprises the following steps: voice prompt, buzzer prompt or indicator light prompt.
The invention also provides a water heater, which comprises a storage chip for storing backup data, and the water heater prevents abnormal shutdown by using the method for automatically recovering the operation of the equipment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
