The UE may be a terminal device such as a smart phone, a tablet computer, a notebook computer, a personal digital assistant (Personal Digital Assistance, PDA), etc.
Next, a processing method of the micro control unit of the air conditioner external unit provided by the present application will be described.
Fig. 1 shows a schematic flow chart of a processing method of a micro control unit of an air conditioner external unit according to the present application, and as shown in fig. 1, the processing method of the micro control unit of the air conditioner external unit according to the present application may specifically include the following steps:
step S101, a virtual EEPROM is obtained through virtualization processing in a first storage space on a flash configured by a micro control unit, and the virtual EEPROM is used for simulating the function of an entity EEPROM;
step S102, when the target operation parameters are read from the EEPROM in a triggering manner, the micro control unit reads the target operation parameters from the operation parameters stored in the virtual EEPROM;

step S104, the micro control unit acquires a target running code of a target processing task corresponding to the target running parameter from the second storage space;
in step S105, the micro control unit loads the target running code and the target running parameter to execute the target processing task.
The micro control unit can be seen from the embodiment shown in fig. 1, aiming at the maintenance of the EEPROM of the air conditioner external unit, the application framework of the novel EEPROM is provided, a virtual EEPROM is arranged on the flash of the micro control unit, when the target operation parameter is read from the EPPROM, the micro control unit can read the target operation parameter from the virtual EEPROM, thus, the micro control unit can load the target operation parameter and acquire the target operation code corresponding to the target processing task from the other storage space of the flash, the target processing task is executed, and in the process, due to the fact that the virtual EEPROM is introduced, the replacement of the entity EEPROM can be avoided when the EEPROM of the air conditioner external unit is maintained, the efficiency and the stability of the micro control unit when the operation parameter is fetched from the EEPROM are greatly improved from the virtual perspective, the maintenance time of the EEPROM is shortened to a certain extent, and the maintenance cost of the EEPROM is reduced.
The following will further describe in detail the steps shown in fig. 1 and the specific embodiments that may be adopted in practical applications:
in the present application, it can be understood that, in combination with a schematic diagram of a scenario of the entity EEPROM in the prior art shown in fig. 2, compared with the configuration of the entity EEPROM on the electric control board of the air conditioner external unit in the prior art, the present application adopts a virtual EEPROM mode to realize the normal operation of the air conditioner external unit.
The virtual EEPROM virtually obtains the virtual EEPROM in the specific storage space by dividing a part of the storage space in the flash storage space, and the virtual EEPROM can simulate the working mechanism of a normal EEPROM on the data layer through the configuration of an interface and restore the working scene of an entity EEPROM, so that the working of the EEPROM can be completed more quickly and stably on the basis of the virtual EEPROM because of the characteristics of a communication link on data under the condition of ensuring the realizable working of the complete entity EEPROM.
When the virtual EEPROM is in a maintenance scene of the EEPROM, the operation parameters related to the virtual EEPROM are updated on a data layer, or the updated operation parameters are stored into the virtual EEPROM, so that the virtual EEPROM works in consideration of the characteristics of rapidness and stability, the debugging can be more efficiently completed, the maintenance time of the virtual EEPROM is shortened, and the maintenance cost of the virtual EEPROM is reduced.
Specifically, in the maintenance process of the operation parameters on the virtual EEPROM, the operation parameters to be updated can be transmitted to the micro control unit in a wireless communication mode, so that the micro control unit updates the operation parameters on the virtual EEPROM according to the received operation parameters, and the operation parameters to be updated can be transmitted to the micro control unit in a wired communication mode.
It can be understood that if the wireless communication mode adopted, for example, the air conditioner indoor unit is generally deployed in an urban environment, the wireless communication mode has the characteristics of easy touch and approach, so that wired/wireless connection is easy to be established with the UE at hand of the user, and the operation parameters needing to be updated can be wirelessly transmitted to the air conditioner outdoor unit through the air conditioner indoor unit.
Of course, the UE at hand of the user can also directly establish wireless communication connection with the external air conditioner, and transmit the operation parameters to be updated to the external air conditioner through the wireless communication connection.
Or, the air conditioner external unit can also have an independent wireless communication function, so that the operation parameters needing to be updated can be obtained from the cloud server.
Compared with the wireless communication mode, the wired communication mode has faster and more stable transmission quality and low application cost in data transmission, so the wired transmission mode is still adopted as much as possible in consideration of the fact that the maintenance of the EEPROM of the air conditioner external unit and the updating of the operation parameters on the virtual EPPROM are less in the practical application.
The wired transmission mode may be understood as a communication transmission mode implemented through a physical interface, that is, not only may be a communication transmission mode based on a physical interface and a transmission line, for example, a wired communication connection is configured between the physical interface configured by the micro control unit and a device (UE or other type of device) with an operation parameter that needs to be updated stored outside by using the transmission line; the communication transmission mode based on the physical interface can also be used, for example, equipment with transport parameters needing to be updated stored outside can be directly connected with the physical interface configured by the micro control unit to construct wired communication connection.
The device, which is suitable for practical implementation, stores the operation parameters to be updated in the device when obtaining the operation parameters to be updated based on the wired transmission mode, and may be specifically an entity EEPROM, it may be understood that in the prior art, the operation parameters on the entity EPPROM are updated directly by replacing the entity EEPROM whenever there is an update requirement of the operation parameters.
It can be understood that the entity EPPROM is still adopted as a storage medium of the operation parameters to be updated, so that the entity EPPROM can be transplanted into the maintenance system of the original air conditioning equipment more smoothly in practical application, the maintenance efficiency can be improved, the risk is reduced under the condition of conforming to the updating mode of the original user, the original hardware resource can be utilized to realize, the entity EEPROM is recycled, and the occupation of additional communication resources and hardware resources is avoided, so that the entity EPPROM has higher application value.
For this maintenance scenario, the micro-control unit may be specifically configured to: when the micro control unit monitors that the physical EEPROM is configured, the operating parameters stored by the physical EEPROM are written into the virtual EEPROM.
When the configuration of the entity EEPROM is monitored, the operation parameters stored in the entity EEPROM can be considered as the operation parameters which need to be updated currently, and the operation parameters can be written into the virtual EEPROM for debugging and subsequent application.
Correspondingly, the virtual EEPROM can be directly configured in the flash configured by the micro control unit when the factory is set, and the virtual EEPROM can also be configured in the flash configured by the existing micro control unit, for example, during maintenance, the virtual EEPROM can be deployed in the flash of the original micro control unit which is not configured with the virtual EEPROM and updated, so that the virtual EEPROM works based on the virtual EPPROM and the debugging of operation parameters and the like in the subsequent application.
Correspondingly, when the micro control unit monitors that the physical EEPROM is configured and the virtual EEPROM is not configured, the virtual EEPROM can be obtained by carrying out virtualization processing on the first storage space of the flash of the micro control unit, and the operation parameters stored by the physical EEPROM are written into the virtual EEPEOM.
Wherein, for being more suitable for practical application, the following can be specifically defined: when the micro control unit monitors that a new entity EEPROM is configured, the operating parameters stored by the entity EEPROM are written into the virtual EEPROM.
For example, when a newly configured entity EEPROM (e.g., entity EPPROM when switching from a state without configuration EPPROM to a state with configuration EPPROM) occurs, a entity EEPROM that has not been configured for a historic period of time (e.g., a device identification of entity EPPROM with no configuration record is detected to occur) may be identified as a new entity EEPROM.
Therefore, the operation of continuously writing the running parameters stored in the configured entity EEPROM into the virtual EPPROM can be avoided, repeated processing is reduced, meanwhile, the operation of continuously scanning the entity EPPROM can be avoided, the data processing amount is further reduced, and the effective data processing is improved.
As a further implementation manner suitable for practical use, the monitoring of the entity EEPROM may be implemented specifically by the identifier carried by the entity EEPROM, it may be understood that a preset field may be configured in the EEPROM, where the configuration of the preset field may be understood as being implemented on the basis of the storage space of the entity EEPROM, and the preset field may be an original field of the EEPROM or a field obtained by additional configuration, where the entity EEPROM is located may be identified by the content of the field.
For example, the field contents of "0" and "1" may be configured to identify non-physical EEPROM and physical EEPROM, respectively; alternatively, the field contents of "non-physical EEPROM" and "physical EEPROM" may be directly configured to identify the non-physical EEPROM and the physical EEPROM, respectively.
As a preferred policy, referring to a schematic view of a scenario in which the preset field is configured in the present application shown in fig. 3, the present application may be specifically configured to: in the last address bit of the memory space of the physical EEPROM, a preset parameter date, such as any legal 2-byte 16-ary parameter other than 0x0000 and 0xFFFF, is configured.
In connection with the embodiment shown in fig. 3, reference may be continued to a schematic view of a scenario in which the preset field is applied in the present application shown in fig. 4, to understand the subsequent application of the preset field.
When the preset parameter date is detected, it is obvious that the current connection device can be considered as the entity EEPROM, otherwise, the current connection device is not the EEPROM, under the setting, the rewriting and the configuration of the preset field can be realized to the entity EEPROM more simply, and the current connection device has higher scanning efficiency in practical application, so that the current connection device can be put into practical application better.
Correspondingly, the micro-control unit monitors whether the entity EEPROM is configured, and the method can comprise the following steps:
the micro control unit monitors whether the connected components scan preset identifiers carried by the entity EEPROM, the preset identifiers are configured in a storage space of the entity EEPROM, and the preset identifiers are identifiers configured for the entity EEPROM in advance.
If yes, the micro-control unit determines that the physical EEPROM is configured.
In addition, in addition to storing the operation parameters in the currently accessed EPPROM to the virtual EEPROM in the case of maintenance with the operation parameters that currently need to be updated, another specific application scenario is also disclosed.
In the process of considering updating the original task processing based on the entity EEPROM into the task processing based on the virtual EEPROM, a certain degree of updating risk may exist, and the updating risk may be an artificial updating risk, for example, an air conditioner enterprise pauses the updating of an air conditioner external unit of a certain model, or may also be an updating risk of a machine itself, for example, the entity EEPROM is a newly configured device, and has better service performance and is not obviously affected by long-distance entity routing, so that a more gentle transplanting mechanism may be considered to be introduced when the application is transplanted, for example:
when the micro control unit monitors that the physical EEPROM is abnormal or damaged, the micro control unit triggers the target operation parameters to be read from the virtual EEPROM when the target operation parameters are read from the EEPROM.
It can be understood that the operation parameters in the physical EEPROM may be stored in the virtual EEPROM in advance, and at this time, the backup function of the operation parameters is mainly played, and the specific processing of the processing task of the air conditioner external unit by using the operation parameters in the virtual EEPROM is not implemented yet, which may be understood as the preparation processing for updating the original physical EEPROM into the virtual EEPROM in advance.
Subsequently, when the situation that the entity EEPROM is abnormal or damaged is monitored, namely when the entity EEPROM is difficult to normally finish the work, the original task processing based on the entity EEPROM is updated to the task processing based on the virtual EEPROM, so that the transplanting speed can be effectively slowed down under the condition that the processing task required to be processed can be normally finished, and the updating risk mentioned above is avoided.
In addition, under the setting, if the real-time updating requirement appears, the original task processing based on the entity EEPROM can be updated into the task processing based on the virtual EEPROM in time through an instruction or manual triggering.
The above is an explanation of the processing method of the micro control unit of the air conditioner external unit, and in order to facilitate better implementation of the processing method of the micro control unit of the air conditioner external unit provided by the application, the application also provides a processing device of the micro control unit of the air conditioner external unit.
