Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Fig. 1 is a schematic view of an application scenario of an air conditioning device according to an exemplary embodiment of the present disclosure. As shown in figure 1 of the drawings, in which, the air conditioner may include an indoor unit 101 and an outdoor unit 102. The indoor unit 101 may establish a communication connection with the outdoor unit 102 to implement information interaction, signaling control, and the like between the two.
For example, the indoor unit 101 may include an indoor unit controller, such as an indoor unit micro control unit MCU, and the outdoor unit 102 may include an outdoor unit controller, such as an outdoor unit micro control unit MCU. The indoor unit controller and the outdoor unit controller can be communicatively coupled to each other, so as to realize transmission of signals and data between the indoor unit 101 and the outdoor unit 102. The indoor unit 101 operates according to indoor unit control parameters; the outdoor unit 102 operates according to outdoor unit control parameters. Typically, the indoor unit control parameters are stored locally in the indoor unit 101 and the outdoor unit control parameters are stored locally in the outdoor unit 102. If the control parameters required by each of the indoor unit 101 and the outdoor unit 102 cannot be read normally from the local area, the normal operation of the air conditioner is affected.
In order to solve the problem, the present disclosure proposes a method for processing a control parameter, which is applied to a first device, where the first device is one of an indoor unit and an outdoor unit of an air conditioner. Referring to fig. 2, the method includes the steps of:
step S202, sending a first data obtaining instruction to a second device, where the first data obtaining instruction is used to request to obtain a second control parameter of the second device.
Wherein, the second equipment is the other one in air conditioning indoor set and the air condensing units. Exemplarily, if the first device is an air conditioner indoor unit, the second device is an air conditioner outdoor unit; and if the first equipment is the air conditioner outdoor unit, the second equipment is the air conditioner indoor unit.
The air-conditioning indoor unit and the air-conditioning outdoor unit respectively have corresponding control parameters. The control parameters of the indoor unit of the air conditioner may include, but are not limited to: the control parameters related to the internal blower and the electronic expansion valve, and the control parameters of the outdoor unit of the air conditioner may include, but are not limited to: and controlling parameters of a fan of the outdoor unit.
For the sake of convenience of distinction, in the present disclosure, the control parameter of the first device is referred to as a first control parameter, and the control parameter of the second device is referred to as a second control parameter.
Step S204, receiving the second control parameter sent by the second device.
And the second equipment responds to the first data acquisition instruction, reads the second control parameter stored locally and sends the second control parameter to the first equipment.
And step S206, storing the received second control parameter into a first memory.
Wherein the first memory acts as a buffer for the received second control parameter. Illustratively, the first memory may be a Random Access Memory (RAM).
Step S208, verifying the second control parameter stored in the first memory.
The first device and the second device may be abnormal in communication, so that the second control parameter received by the first device may not be consistent with the second control parameter sent by the second device. Therefore, in order to verify that the second control parameter received by the first device is the second control parameter sent by the second device, and ensure the accuracy and reliability of the subsequent data storage, in step S208, the second control parameter buffered in the first memory is checked.
Step S210, in response to the verification passing, storing the second control parameter stored in the first memory into a second memory, where the second memory is a nonvolatile memory and is different from the first memory.
When the second control parameter check passes, it indicates that the second control parameter received by the first device is consistent with the second control parameter sent by the second device, and it may be considered that the second control parameter received by the first device is accurate and valid, and therefore, the second control parameter is stored in the second memory. The second memory is a nonvolatile memory, and the nonvolatile memory has a power-down holding function, so that the safety of data storage can be improved. Illustratively, the second memory may be a flash memory (flash).
In the above technical solution, the first device sends a data obtaining instruction to the second device to request to obtain the control parameter of the second device, and caches the received control parameter in the first memory, and then verifies the received control parameter, and when the verification passes, stores the control parameter in the second memory. Therefore, the control parameters of the second device are effectively stored in the first device, the second device plays a role in remotely backing up the control parameters, even if the second device is powered on next time and locally acquires the required control parameters, the second device can still acquire the required control parameters from the first device due to the fact that redundant backup of the control parameters of the second device is carried out in the first device before, and normal operation of the second device is guaranteed. In addition, the received control parameters of the second device are firstly cached, then verified, and after the verification is passed, the control parameters are stored in the nonvolatile memory. Therefore, on one hand, the control parameters of the second equipment are stored in the nonvolatile memory after passing the verification, so that the accuracy and the validity of the control parameters of the second equipment stored in the first equipment can be ensured, on the other hand, the control parameters passing the verification are stored in the nonvolatile memory, and the safety of data storage can be improved by utilizing the characteristic of power failure retention of the nonvolatile memory.
In at least one embodiment, when the second control parameter fails to be verified, step S202 may be executed again, that is, the first data acquisition instruction is sent to the second device again. Or outputting communication abnormity information to prompt the user that the communication between the first device and the second device is abnormal. Or, when the second control parameter check fails, step S202 may be executed again, and after step S202 is executed again for several times, the second control parameter check still fails, and then the communication abnormality information is output.
FIG. 3 is a flow chart illustrating a method of processing control parameters according to an exemplary embodiment. As shown in fig. 3, the method for processing the control parameter may further include the following steps:
step S212, in response to receiving a second data obtaining instruction sent by a second device, reading a second control parameter from a second memory, where the second data obtaining instruction is used to request to obtain a second control parameter of the second device;
step S214, sending the read second control parameter to the second device.
When the second device is powered on, the second control parameter may be obtained locally first. If the local acquisition of the second control parameters fails, the second device may send a second data acquisition instruction to the first device to request acquisition of the second control parameters from the first device. Accordingly, after receiving the second data acquisition instruction, the first device may read the stored second control parameter from the second memory because the second control parameter is previously stored in the second memory, and then send the read second control parameter to the second device. In this way, the second device may acquire the control parameter required by itself from the first device and operate based on the second control parameter acquired from the first device.
Through the technical scheme, under the condition that the second equipment fails to locally acquire the second control parameter, the second control parameter backed up in the first equipment can be acquired from the first equipment, so that the second equipment can still normally operate.
FIG. 4 is a flow diagram illustrating a method of processing control parameters in accordance with an exemplary embodiment. As shown in fig. 4, before step S202, the method may further include:
step S216, receiving second check-up information sent by the second device, where the second check-up information may include at least one of the following: the product serial number of the second device and the first check value of the second control parameter.
Wherein, when the second device is powered on, the second device may first read its own product serial number (i.e., SN number). If the second device reads the product serial number of the second device, the target control parameter matched with the product serial number of the second device can be obtained as the second control parameter required by the second device by inquiring the corresponding relation between the product serial number and the second control parameter according to the product serial number. At this time, the second device may calculate a first check value of the second control parameter based on the second control parameter and a preset check algorithm.
Or, if the second device does not read its own serial number, it may still read a third memory provided on its own side to obtain the second control parameter from the third memory. Before the second device was last powered down, the second control parameters it used may be stored in a third memory, which is a non-volatile memory, such as a flash. Therefore, when the second device is powered on at this time, if the product serial number of the second device is not read, the second device can continuously read the second control parameter from the third memory, so that the local redundancy backup of the second control parameter in the second device is improved. After reading the second control parameter from the third memory, the second device may calculate a first check value of the second control parameter based on the second control parameter and a preset check algorithm.
The check algorithm can be a cyclic redundancy check code algorithm, a hash encryption algorithm, and the like.
After reading the product serial number of the second device or after calculating the first check value of the second control parameter, the second device may send second check information to the first device, where the second check information may include at least one of the following: the product serial number of the second device and the first check value of the second control parameter.
Step S218, determining whether the second control parameter needs to be acquired from the second device according to the second check information.
After receiving the second check information, the first device may determine whether the second control parameter needs to be acquired from the second device according to the second check information.
For example, the first device determines that the second control parameter needs to be obtained from the second device in response to any one of the following conditions being met:
the second memory does not store the second control parameter;
the received product serial number of the second device is inconsistent with the product serial number of the second device stored in the second memory;
the received first check value is inconsistent with the check value of the second control parameter stored in the second memory.
When the first device and the second device normally operate, the nonvolatile memory on the self side can store the product serial number of the other side, the control parameter of the other side and the check value of the control parameter of the other side. If the second control parameter is not stored in the second memory on the first device side, the first device determines that the second control parameter needs to be acquired from the second device.
Or, due to device replacement or other reasons, the device performing information interaction this time may be different from the previous device, for example, if the second device is replaced, the product serial number of the original second device currently stored in the second memory of the first device and the check value of the second control parameter of the original second device may be mismatched with the current second device, and therefore, if the product serial number in the received second check information is inconsistent with the product serial number of the second device stored in the second memory, or the first check value in the received second check information is inconsistent with the check value of the second control parameter stored in the second memory, the first device determines that the second control parameter of the current second device needs to be acquired from the second device.
Determining from the second check-up information when the second device acquires the second control parameter, the first device sends the first data acquisition instruction to the second device, that is, the step S202 is executed.
Through the technical scheme, the second control parameter which is valid last time of the second equipment can be ensured to be always stored in the second memory of the first equipment, so that when the second equipment reversely acquires the second control parameter from the first equipment, the first equipment provides the second control parameter which is valid last time to the second equipment.
In at least one embodiment, the first device may store the received second check-up information in the first memory after receiving the second check-up information. That is, the second check-up information is cached in the first memory.
Thereafter, the first device may verify the second control parameter stored in the first memory by:
determining a second check value of the second control parameter according to the second control parameter stored in the first memory;
determining that the second control parameter stored in the first memory passes the check in response to the first check value being consistent with the second check value.
Illustratively, after the first device sends the first data acquisition instruction to the second device, the first device receives the second control parameter returned by the second device and caches the second control parameter in the first memory. In addition, after receiving the second check-up information sent by the second device, the first device also caches the second check-up information in the first memory. Wherein the second check information includes a first check value of the second control parameter. In this way, the first device may verify the second control parameter stored in the first memory with the first verification value stored in the first memory. For example, a second check value of the second control parameter is calculated according to the second control parameter stored in the first memory and a preset check algorithm. The verification algorithm used by the first device when obtaining the second verification value is the same as the verification algorithm used by the second device when obtaining the first verification value, and the two devices can preset the same type of verification algorithm used. When the first check value stored in the first memory is consistent with the second check value calculated by the first device, it indicates that the second control parameter received by the first device is consistent with the second control parameter sent by the second device, at this time, it is determined that the second control parameter stored in the first memory passes the check, and then, the second control parameter is stored in the second memory. When the first check value stored in the first memory is inconsistent with the second check value calculated by the first device, it indicates that the second control parameter received by the first device is inconsistent with the second control parameter sent by the second device, and at this time, it is determined that the second control parameter stored in the first memory fails to be checked.
In at least one embodiment, the first device may delete the second check-up information stored in the first memory when the second control parameter stored in the first memory fails to pass the check-up.
In at least one embodiment, the method for processing the control parameter may further include:
storing the second check-up information stored in the first memory into the second memory in response to a check-up pass.
That is, when it is determined that the second control parameter stored in the first memory passes the verification, the first device stores the second verification information cached in the first memory into the second memory. Therefore, after the first device is powered off, the latest product serial number and/or the check value of the second control parameter of the second device can still be effectively stored in the second memory.
In at least one embodiment, the method for processing the control parameter may further include:
sending first verification information to a second device, the first verification information including at least one of: the product serial number of the first device and a third check value of the first control parameter of the first device.
After being powered on, the first device also obtains the first control parameter required by the first device from the local. As described above, the first device and the second device may perform redundant backup of the control parameters with each other. That is, the second device may store the first control parameter of the first device, the check value of the first control parameter, and the product serial number of the first control parameter in the third memory on its own side.
The first device, when powered on, may first read its own product serial number (i.e., SN number). If the first device reads the product serial number of the first device, the target control parameter matched with the product serial number of the first device can be obtained as the first control parameter required by the first device by inquiring the corresponding relation between the product serial number and the first control parameter according to the product serial number. At this time, the first device may calculate a third verification value of the first control parameter based on the first control parameter and a preset verification algorithm.
Or, if the first device does not read its product serial number, it may still read a second memory provided on its own side to obtain the first control parameter from the second memory. The first control parameter used by the first device may be stored in the second memory before it was last powered down. Therefore, when the first device is powered on at this time, if the product serial number of the first device is not read, the first device can continuously read the first control parameter from the second memory, so that the local redundancy backup of the first control parameter in the first device is improved. After the first control parameter is read from the second memory, the first device may calculate a third check value of the first control parameter based on the first control parameter and a preset check algorithm.
The check algorithm can be a cyclic redundancy check code algorithm, a hash encryption algorithm, and the like.
After reading the product serial number of the first device or after calculating the third check value of the first control parameter, the first device may send first check information to the second device, where the first check information may include at least one of the following: the product serial number of the first device and the third check value of the first control parameter.
After receiving the first check information sent by the first device, the second device may determine, according to the first check information, whether the first control parameter needs to be acquired from the first device and how the first device checks the second control parameter by using the second check information in the same manner as described above, that how the first device determines whether the second control parameter needs to be acquired from the second device according to the second check information, and how the first device checks the second control parameter by using the second check information, which is not described in detail herein.
In at least one embodiment, the method for processing the control parameter may further include:
when the first equipment is powered on, responding to the product serial number which is not read to the first equipment, and reading a first control parameter of the first equipment from the second memory;
responding to the condition that the first control parameter is not read, and sending a third data acquisition instruction to the second equipment, wherein the third data acquisition instruction is used for requesting to acquire the first control parameter;
receiving the first control parameter sent by the second device;
and controlling the first equipment to operate according to the first control parameter.
As described above, when the first device is powered on, the locally recorded product serial number of the first device is preferentially read. If the local record is empty or the product serial number of the first device is not successfully read, the first control parameter of the first device is read from the second memory. If the first control parameter is not successfully read from the second storage due to abnormal reading or storage failure, the first device may ask the second device for help by sending a third data acquisition instruction to the second device to request acquisition of the first control parameter. After receiving the third data obtaining instruction, the second device obtains the first control parameter of the first device from local, for example, reads from the third memory of the local side. And then, the second equipment sends the first control parameter of the first equipment to the first equipment. After receiving the first control parameter sent by the second device, the first device may control the first device to operate according to the first control parameter.
Therefore, even if the first device fails to obtain the first control parameter required by the first device from the local, the first device can also obtain the first control parameter of the redundant backup in the second device from the second device, and the first device can be ensured to normally operate.
In at least one embodiment, the method for processing the control parameter may further include: storing the received first control parameter in the second memory.
That is, after acquiring the first control parameter of the first device from the second device, the first device may store the first control parameter in the second memory. Therefore, once the product serial number of the first product is not read when the first device is powered on next time, the first control parameter used in the previous operation can also be read from the second memory, so that the first device can successfully obtain the first control parameter required by the operation locally.
It is worth mentioning that the above described processing method applied to the control parameter on the side of the first device is equally applicable to the second device. That is, by swapping the first device and the second device involved in the above-described method, swapping the first control parameter and the second control parameter, replacing the first memory with a nonvolatile memory on the second device side, that is, a third memory, and replacing the second memory with a fourth memory (for example, a RAM) on the second device side, which is different from the third memory, the processing method applied to the control parameter on the second device side can be implemented. The detailed flow is not described herein.
