[0029] Embodiment one

[0030] Figure 1A flowchart of an encryption method of a heat pump unit is provided for Embodiment One of the present application. The present embodiment can be applied to the encryption of a heat pump unit. The method can be executed by an encryption device of the heat pump unit, which can be realized in the form of hardware and / or software, and can be configured in the heat pump unit. As shown in FIG. 1, the method comprises the following steps. Figure 1

[0031] S110, reading the unique identification code of the heat pump unit at the first power-on before the heat pump unit is shipped.

[0032] The unique identification code of the heat pump unit can be understood as an identification code capable of uniquely identifying the heat pump unit. For example, the unique identification code of the heat pump unit can include the heat pump unit shipment barcode, the heat pump unit control panel ROM ID number, and the product heat pump unit networking module IME number, etc. It can also include a unique identification code formed by permutation and combination of at least two types of identification codes mentioned above, or a self-defined identification code with unique identification function.

[0033] Specifically, after the heat pump unit is completed and manufactured, it will be powered on one or more times before being shipped for testing. At the first power-on before the heat pump unit is shipped, the unique identification code of the heat pump unit is obtained through the control panel of the heat pump unit.

[0034] S120, generating the boot encryption password and the test encryption password according to the unique identification code and the multi-factor password generation algorithm, and respectively encrypting the heat pump unit according to the boot encryption password and the test encryption password.

[0035] The multi-factor password generation algorithm is a password generation algorithm used to generate the password required for encryption or decryption. Since the password generation algorithm is determined by multiple password factors based on specific password calculation logic, it is called a multi-factor password generation algorithm. The boot encryption password is a password for the boot mode entered by the offline user for the mirror use of the heat pump unit. The test encryption password is a password for the test state entered for the test of the heat pump unit before being shipped.

[0036] Specifically, the unique identification code of the heat pump unit is input into the multi-factor password generation algorithm to obtain the boot encryption password and the test encryption password respectively. The boot encryption password is used to encrypt the parameters or software systems used in the boot mode of the heat pump unit. The test encryption password is used to encrypt the parameters or software systems used in the test state of the heat pump unit.

[0037] ​When decryption of the heat pump unit is required, the responding decryption password can be selected according to the actual application scenario to decrypt the heat pump unit. Specifically, the start-up decryption password can be selected to decrypt the heat pump unit in the start-up working mode, so that the heat pump unit enters the start-up working mode, facilitating normal use of the heat pump unit by the user; or the test decryption password can be selected to decrypt the heat pump unit in the test state, so that the heat pump unit enters the test state, facilitating pre-shipment testing of the heat pump unit.

[0038] For example, the start-up encryption password and the test encryption password can be generated according to the unique identification code and the multi-factor password generation algorithm. The start-up encryption password and the test encryption password can be generated by inputting the unique identification code of the heat pump unit into the same multi-factor password generation algorithm, so that the same start-up encryption password and test encryption password are obtained. Alternatively, the unique identification code of the heat pump unit can be input into a first multi-factor password generation algorithm to obtain the start-up encryption password, and the unique identification code of the heat pump unit can be input into a second multi-factor password generation algorithm to obtain the test encryption password. The start-up encryption password and the test encryption password are different.

[0039] S130, setting the unit encryption and decryption flag stored in the memory of the heat pump unit to an encryption state.

[0040] The unit encryption and decryption flag can be understood as a flag for identifying whether the heat pump unit is currently in an encryption state or an unencrypted state. The unit encryption and decryption flag is stored in the memory inside the heat pump unit.

[0041] Specifically, after the heat pump unit is encrypted by the start-up encryption password and the test encryption password, the unit encryption and decryption flag stored in the memory of the heat pump unit is set to an encryption state, indicating that the heat pump unit is currently in an encryption state.

[0042] For example, the unit encryption and decryption flag is F_unlock_password_ok. F_unlock_password_ok can be set to 0 to indicate that the heat pump unit is currently in an encryption state, or F_unlock_password_ok can be set to 1 to indicate that the heat pump unit is currently in a decryption state. Alternatively, F_unlock_password_ok can be set to 0 to indicate that the heat pump unit is currently in an encryption state, F_unlock_password_ok can be set to 1 to indicate that the heat pump unit is currently in a test decryption state, and F_unlock_password_ok can be set to 2 to indicate that the heat pump unit is currently in a start-up decryption state.

[0043] The technical scheme of the embodiment of the present application comprises the following steps: reading the unique identification code of the heat pump unit when the heat pump unit is powered on for the first time before leaving the factory; generating a start-up encryption password and a test encryption password according to the unique identification code and a multi-factor password generation algorithm, and respectively encrypting the heat pump unit according to the start-up encryption password and the test encryption password; and setting the unit encryption and decryption flag stored in the memory of the heat pump unit to an encryption state. The multi-factor password generation algorithm is used to automatically generate the start-up encryption password and the test encryption password, which solves the problem that the encryption method of the existing heat pump unit is relatively complex and is not convenient for users to use when offline and to test when leaving the factory. Meanwhile, the method is compatible with double encryption control of users and production, which not only guarantees the market security encryption control requirement, but also meets the convenience of internal product production, testing, installation and debugging, etc., and realizes the safety of the heat pump unit while improving the portability of the heat pump unit encryption and decryption.

[0044] Embodiment two

[0045] Figure 2A A flowchart of an encryption method of a heat pump unit provided by the second embodiment of the present application, the embodiment further limits step S120 between the above-mentioned embodiments to "the generation of the start-up encryption password and the test encryption password according to the unique identification code and the multi-factor password generation algorithm comprises: generating the start-up encryption password according to the unique identification code and a first multi-factor password generation algorithm; and generating the test encryption password according to the unique identification code and a second multi-factor password generation algorithm; wherein the first multi-factor password generation algorithm and the second multi-factor password generation algorithm are different".

[0046] As shown in Figure 2A , the method comprises the following steps:

[0047] S210, reading the unique identification code of the heat pump unit when the heat pump unit is powered on for the first time before leaving the factory.

[0048] S220, generating a start-up encryption password according to the unique identification code and a first multi-factor password generation algorithm.

[0049] The first multi-factor password generation algorithm is used to generate the start-up encryption password.

[0050] Specifically, the unique identification code is input into the first multi-factor password generation algorithm to obtain the start-up encryption password Real_code.

[0051] S230, generating a test encryption password according to the unique identification code and a second multi-factor password generation algorithm.

[0052] The second multi-factor password generation algorithm is used to generate the test encryption password, and the first multi-factor password generation algorithm and the second multi-factor password generation algorithm are different. Therefore, the start-up encryption password and the test encryption password are different.

[0053] Specifically, the unique identification code is input into the second multi-factor password generation algorithm to obtain a test encryption password Test_code. Since the first multi-factor password generation algorithm and the second multi-factor password generation algorithm are different, the boot encryption password and the test encryption password are also different, so that the encryption of the boot working mode and the test state of the heat pump unit is independent of each other, and the passwords are not communicated with each other. The safety of the test and use of the heat pump unit is improved.

[0054] S240, the heat pump unit is encrypted according to the boot encryption password and the test encryption password.

[0055] S250, the unit encryption and decryption flag stored in the memory of the heat pump unit is set to an encryption state.

[0056] The technical scheme of the embodiment of the application comprises the following steps: reading a unique identification code of a heat pump unit when the heat pump unit is powered on for the first time before leaving the factory; generating a boot encryption password according to the unique identification code and a first multi-factor password generation algorithm; wherein the first multi-factor password generation algorithm and a second multi-factor password generation algorithm are different; generating a test encryption password according to the unique identification code and the second multi-factor password generation algorithm; encrypting the heat pump unit according to the boot encryption password and the test encryption password; and setting a unit encryption and decryption flag stored in a memory of the heat pump unit to an encryption state. The boot encryption password and the test encryption password are automatically generated by using different multi-factor password generation algorithms, which solves the problem that the encryption method of the existing heat pump unit is relatively complex and is not convenient for use by a user offline and for testing when leaving the factory, further improves the safety of the heat pump unit, and improves the portability of the encryption and decryption of the heat pump unit.

[0057] After the unit encryption and decryption flag of the heat pump unit is set to the encryption state, the heat pump unit can also be decrypted by using a decryption password. The encryption process of the heat pump unit is described in the following embodiments.

[0058] Optionally, after the unit encryption and decryption flag stored in the memory of the heat pump unit is set to the encryption state, the method further comprises the following steps:

[0059] S261, reading the unit encryption and decryption flag stored in the memory when the heat pump unit is powered on after leaving the factory.

[0060] Specifically, the heat pump unit is powered on in a scenario where the heat pump unit leaves the factory and a user needs to boot the heat pump unit for use. After the heat pump unit is powered on, the control board of the heat pump unit reads the unit encryption and decryption flag F_unlock_password_ok stored in the internal memory of the heat pump unit to check whether the heat pump unit is currently in an unencrypted state, i.e., an encryption state.

[0061] S262, in the case that the unit encryption and decryption flag indicates that the heat pump unit is in an encryption state, when the start-up decryption password is obtained, the start-up decryption password is used to unlock the start-up operation mode of the heat pump unit. The start-up decryption password is generated by the server according to the unique identification code and a first multi-factor password generation algorithm. The unique identification code is determined by the server according to the heat pump unit information uploaded by the terminal device.

[0062] In the embodiment, the heat pump unit can be connected with the server to realize information interaction between the heat pump unit and the server, so as to facilitate complex calculation on the server. The server can be a cloud server or other type of server, and the embodiment of the present application does not limit this. The heat pump unit can also be connected with the terminal device to facilitate information interaction between the user and the heat pump unit through the terminal device. The terminal device can be a mobile phone, a tablet computer or a smart gateway, and the embodiment of the present application does not limit this. The connection mode between the heat pump unit and the server and the terminal device can be a wired mode, or a local area network, Bluetooth, WIFI or other wireless connection mode, and the embodiment of the present application does not limit this.

[0063] Specifically, if it is determined according to the unit encryption and decryption flag that the heat pump unit is currently in an encryption state, the heat pump unit requests the server to obtain a start-up decryption password, and the server requests the terminal device to obtain a unique identification code of the heat pump unit after receiving the request. After obtaining the unique identification code sent by the terminal device, the server inputs the unique identification code into a first multi-factor password generation algorithm to generate a start-up decryption password SET_code, and sends the start-up decryption password to the heat pump unit or the terminal device.

[0064] If the start-up decryption password is sent to the heat pump unit, the heat pump unit can directly obtain the start-up decryption password and use the start-up decryption password to unlock the start-up operation mode of the heat pump unit; if the start-up decryption password is directly sent to the terminal device to display the start-up decryption password to the user, the heat pump unit can obtain the start-up decryption password input by the user or sent by the terminal device through the control panel of the heat pump unit, and use the start-up decryption password to unlock the start-up operation mode of the heat pump unit.

[0065] It should be noted that, since the same first multi-factor password generation algorithm is used to generate the start-up decryption password SET_code and the start-up encryption password Real_code, the start-up decryption password and the start-up encryption password are the same.

[0066] The unique identification code of the heat pump unit is determined by the server according to the heat pump unit information uploaded by the terminal device. The specific method can be that the server receives the heat pump unit information uploaded by the user to the heat pump unit through the terminal device, and determines the unique identification code of the heat pump unit by performing information recognition and analysis on the heat pump unit information.

[0067] Exemplarily, the server can send the start-up decryption password to the terminal device in the following manners: through a specific communication frequency band, using a short message verification code, remote control, or other manners to send the start-up decryption password to the client of the terminal device for decryption.

[0068] Exemplarily, the manner of unlocking the start-up operation mode of the heat pump unit by using the start-up decryption password can be that the terminal device directly sends the start-up decryption password to the heat pump unit; after receiving the decryption password SET_code, the heat pump unit compares the decryption password SET_code with the start-up encryption password Real_code. If they are the same, the heat pump unit determines that the decryption password SET_code is the start-up decryption password, and uses the start-up decryption password SET_code to unlock the start-up operation mode of the heat pump unit, so that the heat pump unit enters a normal operation state.

[0069] Optionally, the heat pump unit information includes: a heat pump unit installation site map, a heat pump unit factory bar code, and heat pump unit use reserved use information.

[0070] The heat pump unit installation site map refers to a site map of installing the heat pump unit by the user, and the heat pump unit factory bar code refers to

[0071] Specifically, the user uploads the heat pump unit installation site map, the heat pump unit factory bar code, and the heat pump unit use reserved use information to the server through the terminal device. The server audits whether the heat pump unit is installed correctly according to the heat pump unit installation site map to ensure the safety of the heat pump unit installation; determines the type of the heat pump unit and other information according to the heat pump unit factory bar code, and then obtains the pre-set unique identification code of the heat pump unit, and audits whether the actual use information of the heat pump unit and the recorded heat pump unit use information are consistent according to the heat pump unit use reserved use information, to ensure the subsequent updating, regular maintenance and repair work of each heat pump unit.

[0072] S263、In the unlocked start-up operation mode of the heat pump unit, the unit encryption and decryption flag is set to a decryption state.

[0073] Specifically, after the start-up operation mode of the heat pump unit is unlocked, the unit encryption and decryption flag of the heat pump unit is set to a decryption state, so that after the heat pump unit is powered off and powered on again, the unit encryption and decryption flag is in the decryption state, and therefore the heat pump unit can directly enter the working state without decryption again.

[0074] Optionally, after setting the unit encryption and decryption flag stored in the memory of the heat pump unit to an encryption state, the method further includes:

[0075] S271, when the heat pump unit is powered on, reading the unit encryption and decryption flag stored in the memory.

[0076] Specifically, the test personnel may need to test the heat pump unit before the heat pump unit is shipped, the user or the sales personnel may need to experience or test the heat pump unit before the heat pump unit is sold, and the after-sales installer may need to test the heat pump unit after the heat pump unit is sold. In the above scenarios, the heat pump unit needs to be temporarily decrypted. When the heat pump unit is powered on, the control panel of the heat pump unit reads the unit encryption and decryption flag F_unlock_password_ok stored in the internal memory of the heat pump unit, and checks whether the heat pump unit is currently in an unencrypted state, i.e., an encrypted state.

[0077] S272, in the case where the unit encryption and decryption flag indicates that the heat pump unit is in an encrypted state, when the test decryption password is obtained, it is determined whether the test decryption password is within a valid period according to the cumulative time of the heat pump unit entering the test operation mode.

[0078] The valid period is set to different times according to different test conditions and other information of the heat pump unit.

[0079] Specifically, if it is determined according to the unit encryption and decryption flag that the heat pump unit is currently in an encrypted state, when the decryption password is received, the decryption password and the test encryption password Test_code are compared. If they are the same, the heat pump unit determines that the decryption password SET_code is the test decryption password, and determines whether the test decryption password is within a valid period according to the cumulative time of the heat pump unit entering the test operation mode.

[0080] The way of determining whether the test decryption password is within a valid period according to the cumulative time of the heat pump unit entering the test operation mode is: obtaining the cumulative time of the heat pump unit entering the test operation mode, if the cumulative time is less than or equal to a preset time, it is determined that the test decryption password is within a valid period; if the cumulative time is greater than the preset time, it is determined that the test decryption password is not within a valid period.

[0081] Optionally, the test decryption password directly input by the user is obtained through the control panel or the terminal device of the heat pump unit.

[0082] Optionally, the test decryption password is generated by the server according to the unique identification code sent by the terminal device and the second multi-factor password generation algorithm.

[0083] Specifically, the server obtains the unique identification code of the heat pump unit input on the terminal device, or obtains the unique identification code of the heat pump unit through the heat pump unit information uploaded by the terminal device; inputs the unique identification code of the heat pump unit into the second multi-factor password generation algorithm for generating a test encryption password, obtains a test decryption password same as the test encryption password, and delivers it to the terminal device or the heat pump unit.

[0084] S273, if within the validity period, then based on the test decryption password, the test state of the heat pump unit is decrypted to make the heat pump unit enter the test running mode;

[0085] Specifically, if the test decryption password is within the validity period, the test decryption password SET_code is used to unlock the test state of the heat pump unit, so that the heat pump unit enters the test running mode. Because the test decryption password can also be considered as a temporary decryption password of the heat pump unit.

[0086] S274, when the heat pump unit exceeds the validity period or the heat pump unit is powered off, the heat pump unit is controlled to exit the test running mode and still remains in the encrypted state.

[0087] It should be noted that after the test state of the heat pump unit is unlocked, the heat pump unit can enter an independent test state for pre-shipment, pre-installation and post-installation tests of the heat pump unit. However, the heat pump unit is only in a temporary decryption state, and the encryption and decryption flag F_unlock_password_ok of the unit still remains in the encrypted state. After the heat pump unit exceeds the validity period or is powered off, the heat pump unit is controlled to exit the current test running mode and still remains in the encrypted state. That is, after the heat pump unit exits the current test running mode, the test decryption password needs to be provided next time the heat pump unit is powered on to decrypt the test state of the heat pump unit.

[0088] The present application adopts a multi-factor multi-encryption algorithm, combines a server, an APP background of a terminal device and other Internet platforms for decryption control, strengthens the anti-deciphering mechanism, improves the safety and reliability of the heat pump unit, ensures the safety of user information, and optimizes the intelligent integrated heat pump unit control technology.

[0089] Optionally, the multi-factor password generation algorithm comprises:

[0090] Step 1: generating a password factor according to the unique identification code of at least one type of heat pump unit.

[0091] Illustratively, the password factor is generated by the unique identification code UNIT_CODE of at least one type of heat pump unit. The password factor can be composed of a single unique identification code of the heat pump unit, for example, (1) the password factor 1 is the product heat pump unit factory bar code; (2) the password factor 2 is the product heat pump unit control panel ROM_ID number; (3) the password factor 3 is the product heat pump unit networking module IME number; (4) the password factor 4 is a self-defined unique identification code. The password factor can be composed of a sequence of multiple unique identification codes arranged and combined; the password factor 5 is a sequence of multiple unique identification codes (such as: product heat pump unit factory bar code + product heat pump unit control panel ROM_ID number).

[0092] Step 2: splitting the password factor to obtain a plurality of calculation factors based on a preset factor bit splitting mode.

[0093] For example, the calculation factors are obtained by splitting the password factor by bit, such as: (1) password factor 1 is split to obtain 16 calculation factors of bit0,...bit15; (2) password factor 2 is split to obtain 2 calculation factors of bit0~bit7 and bit8~bit15; (3) password factor 3 is split to obtain 4 calculation factors of bit0~bit3, bit4~bit7, bit8~bit11 and bit12~bit15; (4) password factor 4 is split to obtain n1(n1≥2) calculation factors; (5) password factor 5: the permutation sequence of the multiple unique identification codes is split to obtain n2(n2≥2) calculation factors.

[0094] Step 3: inputting each of the calculation factors into a preset calculation formula to obtain a password; the password includes an encryption password or a decryption password.

[0095] The preset calculation formula is a formula for generating a password based on a password factor, which can be a CRC, MD5, accumulation, or other calculation formula, or a self-defined calculation formula.

[0096] For example, each of the calculation factors obtained by splitting the password factor by bit is input into the preset calculation formula to obtain the password.

[0097] It should be noted that the steps of the multi-factor password generation algorithm can be applied to generate the encryption password or the decryption password required by any of the above embodiments, including: a boot encryption password, a boot decryption password, a test encryption password, and a test decryption password. Therefore, the multi-factor password generation algorithm can be a first multi-factor password generation algorithm for generating a boot encryption password and a boot decryption password, or a second multi-factor password generation algorithm for generating a test encryption password and a test decryption password.

[0098] Figure 2B is a flowchart of a decryption method of a heat pump unit according to an embodiment of the present application. In a specific example, as shown in Figure 2BAs shown, the heat pump unit reads the unit encryption and decryption flag F_unlock_password_ok in the memory through the control panel; it is judged whether the unit encryption and decryption flag indicates that the heat pump unit is in an encrypted state, for example, it is judged whether F_unlock_password_ok == 1, which indicates that the heat pump unit is in an encrypted state, then the display panel of the heat pump unit displays the unencrypted interface, reminding the user to decrypt. And when the server reads the unique identification code of the heat pump unit, based on the unique identification code and the multi-factor password generation algorithm, the corresponding decryption password SET_code is generated, and the decryption password is sent to the terminal device in various ways such as SMS verification code, remote control, etc. The terminal device acquires the decryption password SET_code and sends the decryption password SET_code to the heat pump unit. The heat pump unit judges whether the decryption password SET_code is consistent with the test encryption password Test_code If consistent, the decryption password SET_code is used to decrypt the test mode of the heat pump unit, and the heat pump unit is controlled to enter the test mode. If not consistent, it is further judged whether the decryption password SET_code is consistent with the start-up encryption password Real_code; if not consistent, the unencrypted state is maintained, the display panel displays the unencrypted interface, and the user is reminded to decrypt; if consistent, the decryption password SET_code is used to encrypt the start-up working mode of the heat pump unit, and the heat pump unit is controlled to enter the start-up working mode. In addition, F_unlock_password_ok = 1 is also set and stored in the internal memory of the control panel, so that the heat pump unit remains in the decrypted state.

[0099] Figure 2C is a flowchart of a decryption method of a test state of a heat pump unit provided by Embodiment Two of the present application. In another specific example, as shown in Figure 2C In the case where the unit encryption and decryption flag indicates that the heat pump unit is in an encrypted state, when the test decryption password is acquired, the heat pump unit reads the validity period Test_run_time of the test decryption password in the memory through the control panel, that is, it is judged whether the cumulative time of the heat pump unit entering the test running mode is greater than the validity period (for example, 3 hours). If yes, it indicates that the test decryption password exceeds the validity period, the heat pump unit exits the test running mode, the control panel returns to the interface waiting for decryption again, and the test decryption password is invalid. If not, it indicates that the test decryption password is within the validity period, then the heat pump unit is decrypted based on the test decryption password, enters and remains in the test running mode. It is judged whether the heat pump unit is powered off in the test running mode, if the heat pump unit is powered off, the heat pump unit exits the test running mode, remains in the unencrypted state, and the control panel returns to the interface waiting for decryption again. If the heat pump unit is not powered off, the heat pump unit is decrypted, enters and remains in the test running mode; at the same time, the cumulative time of the heat pump unit entering the test running mode is acquired, and the cumulative time is stored in the internal memory for reading.
