Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule 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 apparatus according to an exemplary embodiment of the present disclosure. As shown in fig. 1, 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 therebetween.
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, so that signal and data transmission between the indoor unit 101 and the outdoor unit 102 is realized. The indoor unit 101 operates according to indoor unit control parameters; the outdoor unit 102 operates according to the outdoor unit control parameters. Normally, 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 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 this problem, the present disclosure proposes a processing method of a control parameter, which is applied to a first device, which is one of an air conditioning indoor unit and an air conditioning outdoor unit. Referring to fig. 2, the method comprises the steps of:
Step S202, a first data acquisition instruction is sent to a second device, where the first data acquisition instruction is used to request to acquire a second control parameter of the second device.
Wherein the second device is the other of the air-conditioning indoor unit and the air-conditioning outdoor unit. Illustratively, if the first device is an air-conditioning indoor unit, the second device is an air-conditioning outdoor unit; if the first device is an air conditioning outdoor unit, the second device is an air conditioning indoor unit.
The air conditioner indoor unit and the air conditioner outdoor unit are respectively provided with corresponding control parameters. The control parameters of the indoor unit of the air conditioner may include, for example, but not limited to: control parameters related to the inner fan and the electronic expansion valve, and control parameters of the air conditioner outdoor unit may include, for example, but not limited to: and controlling parameters of a fan of the outdoor unit.
For ease 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.
The second device responds to the first data acquisition instruction, reads the locally stored second control parameter, and sends the second control parameter to the first device.
Step S206, storing the received second control parameter in the first memory.
Wherein the first memory serves as a buffer for the received second control parameter. The first memory may be, for example, a random access memory (random access memory, RAM).
Step S208, checking the second control parameter stored in the first memory.
The second control parameter received by the first device may not be consistent with the second control parameter transmitted by the second device, possibly due to some communication anomaly between the first device and the second device. Therefore, in order to confirm that the second control parameter received by the first device is the second control parameter transmitted by the second device, the accuracy and reliability of the subsequent data storage are ensured, and 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 in a second memory, where the second memory is a nonvolatile memory, and the second memory is different from the first memory.
When the second control parameter passes the verification, the second control parameter received by the first device is consistent with the second control parameter sent by the second device, and the second control parameter received by the first device can be considered to be accurate and valid, so that 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. The second memory may be a flash memory (flash), for example.
In the above technical solution, the first device requests to acquire the control parameters of the second device by sending a data acquisition instruction to the second device, buffers the received control parameters in the first memory, then checks them, and stores the control parameters in the second memory when the check passes. In this way, the control parameters of the second device are effectively stored in the first device, and the second device has the function of remotely backing up the control parameters, so that even if the second device fails to locally acquire the control parameters required by the second device when the second device is powered on next time, the second device still can acquire the control parameters required by the second device from the first device due to the redundant backup of the control parameters of the second device in the first device, and the second device can be ensured to normally operate. In addition, the received control parameters of the second device are cached first, then checked, and after the check 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 verification, so that the accuracy and the effectiveness of the control parameters of the second equipment stored in the first equipment can be ensured, and on the other hand, the verified control parameters are stored in the nonvolatile memory, and the safety of data storage can be improved by utilizing the characteristic that the nonvolatile memory has power failure and is kept.
In at least one embodiment, when the second control parameter fails the verification, step S202 may be re-performed, i.e. the first data acquisition instruction is re-sent to the second device. Or outputting communication abnormality information to prompt the user of communication abnormality between the first device and the second device. Or when the second control parameter check is not passed, step S202 may be re-executed, and when the second control parameter check is not passed after re-executing step S202 several times, the communication abnormality information may be 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 above-mentioned control parameter processing method may further include the following steps:
step S212, in response to receiving a second data acquisition instruction sent by a second device, reading a second control parameter from a second memory, where the second data acquisition instruction is used to request acquisition of the second control parameter of the second device;
step S214, transmitting the read second control parameter to the second device.
Wherein the second device may first obtain the second control parameter locally when powered on. If the local acquisition of the second control parameter fails, the second device may send a second data acquisition instruction to the first device to request acquisition of the second control parameter 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, and then send the read second control parameter to the second device, because the second control parameter is stored in the second memory. In this way, the second device can acquire the control parameters required for itself from the first device and operate based on the second control parameters acquired from the first device.
Through the technical scheme, under the condition that the second equipment fails to locally acquire the second control parameters, the second control parameters 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 flowchart illustrating a method of processing control parameters according to an exemplary embodiment. As shown in fig. 4, before step S202, the method may further include:
Step S216, receiving second verification information sent by the second device, where the second verification information may include at least one of the following: the product serial number of the second device, the first check value of the second control parameter.
Wherein the second device may first read its own product serial number (i.e., SN number) upon power-up. If the second equipment reads the own product serial number, the target control parameter matched with the own product serial number can be obtained as the second control parameter required by the second equipment 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 the own product serial number, it may still read a third memory provided on its own side, so as to obtain the second control parameter from the third memory. The second control parameters used by the second device may be stored in a third memory, which is a non-volatile memory, for example a flash, before it was last powered down. Therefore, when the second device is powered on this time, if the product serial number of the second device is not read, the second device can continue to read the second control parameter from the third memory, so that the redundancy backup of the second control parameter in the local area of the second device is improved. After the second control parameter is read 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 may be a cyclic redundancy check code algorithm, a hash encryption algorithm, or the like.
The second device may send second verification information to the first device after reading its own product serial number or after calculating the first verification value of the second control parameter, the second verification information may include at least one of: the product serial number of the second device, 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 verification information.
After receiving the second check-up information, the first device may determine whether the second control parameter needs to be acquired from the second device according to the second check-up information.
For example, the first device determines that the second control parameter is to be acquired from the second device in response to any of the following conditions being met:
the second control parameter is not stored in the second memory;
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 operate normally, the nonvolatile memory on the self side can store the product serial number of the opposite party, the control parameter of the opposite party and the check value of the control parameter of the opposite party. 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 because of equipment replacement or other reasons, the equipment for carrying out information interaction at this time is possibly different from the last time, for example, the second equipment is replaced, and then the product serial number of the original second equipment and the check value of the second control parameter of the original second equipment currently stored in the second memory of the first equipment are not matched with the current second equipment, so if the product serial number in the received second check information is not consistent with the product serial number of the second equipment stored in the second memory, or the first check value in the received second check information is not consistent with the check value of the second control parameter stored in the second memory, the first equipment determines that the second control parameter of the current second equipment needs to be acquired from the second equipment.
When it is determined that the second control parameter needs to be acquired from the second device according to the second check information, the first device transmits the first data acquisition instruction to the second device, that is, performs step S202 described above.
By means of the technical scheme, the fact that the last valid second control parameter of the second device is always stored in the second memory of the first device can be ensured, and therefore when the second device reversely acquires the second control parameter from the first device, the first device provides the last valid second control parameter for the second device.
In at least one embodiment, the first device may store the received second calibration information in the first memory after receiving the second calibration information. That is, the second check information is first cached in the first memory.
The first device may then 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;
And in response to the first check value being consistent with the second check value, determining that the second control parameter stored in the first memory passes a check.
In an example, 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, the first device also buffers the second verification information sent by the second device into the first memory after receiving the second verification information. Wherein the second check information comprises 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, according to the second control parameter stored in the first memory and a preset verification algorithm, a second verification value of the second control parameter is calculated. The check algorithm used by the first device when obtaining the second check value is the same as the check algorithm used by the second device when obtaining the first check value, and the two devices can preset the same check algorithm used. When the first check value stored in the first memory is consistent with the second check value calculated by the first device, the second control parameter received by the first device is consistent with the second control parameter sent by the second device, at the moment, the second control parameter stored in the first memory is determined to pass 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, the second control parameter received by the first device is inconsistent with the second control parameter sent by the second device, and at the moment, the second control parameter stored in the first memory is determined to not pass the check.
In at least one embodiment, the first device may delete the second verification information stored in the first memory when the second control parameter stored in the first memory fails to pass the verification.
In at least one embodiment, the method for processing control parameters may further include:
and storing the second verification information stored in the first memory into the second memory in response to verification passing.
That is, the first device stores the second check information cached in the first memory into the second memory when determining that the second control parameter stored in the first memory passes the check. Therefore, after the first device is powered down, the latest product serial number of the second device and/or the check value of the second control parameter can be still effectively stored in the second memory.
In at least one embodiment, the method for processing control parameters may further include:
Transmitting first verification information to a second device, the first verification information including at least one of: a product serial number of the first device, a third check value of a first control parameter of the first device.
After the first device is powered on, the first control parameter required by the first device is acquired locally. As described above, the first device and the second device may perform redundant backup of control parameters for 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 may first read its own product serial number (i.e., SN number) upon power-up. If the first equipment reads the own product serial number, the target control parameter matched with the own product serial number can be obtained as the first control parameter required by the first equipment 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 check value of the first control parameter based on the first control parameter and a preset check algorithm.
Or if the first device does not read the own product serial number, it may still read the second memory set on the own side, so as to obtain the first control parameter from the second memory. The first control parameters 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 this time, if the product serial number of the first device is not read, the first device can continue to read the first control parameter from the second memory, so that the redundancy backup of the first control parameter in the local area of 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 may be a cyclic redundancy check code algorithm, a hash encryption algorithm, or the like.
The first device may send first verification information to the second device after reading its own product serial number or after calculating a third verification value of the first control parameter, where the first verification information may include at least one of: the product serial number of the first device, the third check value of the first control parameter.
After receiving the first verification information sent by the first device, the second device may determine, according to the first verification information, whether to obtain the first control parameter from the first device and how to verify the first control parameter by using the first verification information, in the same manner how the first device determines, according to the second verification information, whether to obtain the second control parameter from the first device and how to verify the first control parameter by using the first verification information, which are described above, and will not be described in detail herein.
In at least one embodiment, the method for processing control parameters may further include:
When the first device is powered on, reading a first control parameter of the first device from a second memory in response to not reading a product serial number of the first device;
in response to the first control parameter not being read, sending a third data acquisition instruction to the second device, 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 equipment;
And controlling the first equipment to operate according to the first control parameter.
As described above, the first device will preferably read the locally recorded product serial number of the first device when powered on. 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 memory due to the abnormal reading or the storage fault, the first device may call for help to the second device, and request to acquire the first control parameter by sending a third data acquisition instruction to the second device. After receiving the third data acquisition instruction, the second device acquires the first control parameter of the first device locally, for example, reads the first control parameter from a third memory on the local side. The second device then transmits the first control parameter of the first device to the first device. 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 locally acquire the first control parameters required by the first device, the first device can acquire the first control parameters of the redundant backup in the second device from the second device, so that the first device can be ensured to normally operate.
In at least one embodiment, the method for processing control parameters may further include: and storing the received first control parameters into the second memory.
That is, the first device may store the first control parameter into the second memory after acquiring the first control parameter of the first device from the second device. In this way, once the product serial number of the first product is not read when the power is 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 acquire the first control parameter required by the operation locally.
It should be noted that the above-described processing method applied to the control parameter of the first device side is equally applicable to the second device. That is, the first device and the second device involved in the above-described method are swapped, and the first control parameter and the second control parameter are swapped, the first memory is replaced with the nonvolatile memory on the second device side, that is, the third memory, and the second memory is replaced with the fourth memory (for example, RAM) on the second device side, which is different from the third memory, so that the processing method applied to the control parameter on the second device side can be realized. The detailed flow is not described here.
