Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used may be interchanged under appropriate circumstances such that the embodiments of the invention described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those expressly listed steps or units, but may include other units of steps not expressly listed or inherent to these processes, methods, products or devices.

The present invention provides a specific embodiment of a method for configuring a power-on password for a precision air conditioner. It should be noted that the steps shown in the flowcharts of the accompanying drawings may be executed in a computer system, such as a set of computer-executable instructions, and, although a logical sequence is shown in the flowcharts, in some cases, Steps shown or described may be performed in an order different from that herein.

Referring to FIG. 1, it is a flow chart of a specific embodiment of the method for configuring a power-on password of a precision air conditioner disclosed in the present invention. As shown, the following steps are included.

Step S101, a first controller set in the precision air conditioner establishes communication with a second controller set in a control terminal, and the first controller stores the original serial number. Specifically, the first controller (101 shown in FIG. 5 ) is preferably provided in the indoor unit of the precision air conditioner (100 shown in FIG. 5 ), preferably implemented by a control chip in a traditional precision air conditioner. For precision air conditioners, the control terminal (103 shown in Figure 5) is preferably a wired controller, and in some specific cases, it may also be a remote intelligent terminal, and a second controller is provided in the control terminal (see Figure 5). 105), the second controller may be a single-chip microcomputer, or a similar integrated circuit that can realize the same function. Set the set temperature point, set humidity point and air conditioning operation mode of the unit through the wire controller, and strictly control the precision air conditioning unit to operate according to the temperature point, set humidity point and operation mode set through the wire controller. The wired controller outputs the power-on command, the precision air-conditioning unit runs, and the wired controller outputs the shutdown command, and the precision air-conditioning unit stops running. In this embodiment, the first controller and the second controller establish communication. Different from the traditional precision air conditioner, a specific storage unit is preset in the first controller, and the original serial number is stored in the storage unit. The original serial number preferably defaults to all bits being 0.

Step S102, the second controller receives a trigger signal, the second controller generates a boot sequence number according to the generation time of the trigger signal, and outputs the boot sequence number to the first controller to iterate the original sequence number. Specifically, the trigger signal is preferably generated through the human-computer interaction interface (104 shown in FIG. 5 ) set in the control terminal. For example, if the user manually presses the on-off button of the wired controller and keeps it for a certain period of time, the trigger is generated by the on-off button. signal and output to the second controller. The second controller generates the boot sequence number according to the generation time of the trigger signal, and outputs the generated boot sequence number to the first controller to iterate the original sequence number, and the first controller stores the boot sequence number to complete the initialization process.

Step S103 , establish communication with the server (102 shown in FIG. 5 ), and the server receives the boot serial number and generates a boot password according to the boot serial number. Specifically, the second controller can establish two-way communication with the server, and transmit the boot serial number to the server by means of remote transmission. Another optional way is that the boot serial number is displayed through the human-computer interaction interface set on the control terminal. After seeing the boot serial number, the user calls the background service personnel and transmits the boot serial number to the server through remote input. The server receives the power-on serial number and generates a power-on password based on the power-on serial number.

Step S104, the second controller receives and stores the power-on password. Specifically, in the same way, the second controller can establish two-way communication with the server, and transmit the power-on password to the second controller through remote transmission. Input the power-on password to the second controller through the man-machine interface. The second controller stores the power-on password after receiving the power-on password. Under the condition of receiving the trigger signal, the second controller is preferably configured not to output a power-on command by default.

Step S105, after the first controller and the second controller are powered on again, the first controller transmits the boot sequence number to the second controller.

Step S106, the second controller generates a verification password according to the received boot serial number and determines whether the verification password is consistent with the boot password. Preferably, the algorithm for generating the verification password is the same as the algorithm for generating the power-on password, so as to synthesize the set time information of the initial power-on stage to determine whether the current first controller and the second controller match.

Step S1071, if it is determined that the verification password and the power-on password are the same, it means that the first controller and the second controller match, and the operation flow conforms to the normal procedure. The second controller outputs a power-on command. The precision air conditioning unit is controlled to start working according to the temperature set point, humidity set point and working mode set by the second controller.

Step S1072, if it is determined that the verification password and the power-on password are inconsistent, it means that the first controller and the second controller do not match, and the second controller outputs a trigger request signal to require the user to regenerate the trigger signal.

Through the above method, the operation of the unit equipment without strict inspection can be effectively avoided, causing unnecessary failures or unsatisfactory cooling and heating effects. The power-on password can ensure the normal operation of the unit, and can effectively avoid Under abnormal conditions, users set up different units and controllers to use interchangeably, causing unnecessary system failures.

In order to further protect the equipment and avoid the malfunction of the unit due to power failure memory when replacing the control terminal, the following steps are specially designed in the method for configuring the power-on password of the precision air conditioner disclosed in the present invention. If the power-on passwords are inconsistent, the second controller inquires about the power-down memory working state of the precision air-conditioning indoor unit. If the working state of the power-off memory is the power-on state, the second controller outputs a trigger request signal and a shutdown command at the same time, preventing the precision air conditioner from working due to the power-off memory when the verification password and the power-on password are inconsistent.

Referring to FIG. 2, a preferred method for generating a boot serial number is shown. Specifically, the following steps are included.

Step S201, firstly, the generation time of the trigger signal is converted into hexadecimal one by one according to the digits of year, month, day, hour, minute and second.

Step S202, then, generate the boot serial number according to the following formula:

Boot serial number=second*A+minute*B+hour*C+year*D+month*E+day+F, where A, B, C, D, E, and F are any hexadecimal numbers.

Referring to FIG. 3, a preferred method for generating a power-on password according to the power-on serial number is shown. Specifically, the following steps are included.

Step S301, on the server side, firstly, convert the boot serial number transmitted by the user through the phone or by the second controller into a binary number.

Step S302, the low N ₁ bits of the boot serial number converted into binary numbers are shifted left by N ₂ bits to obtain the first intermediate verification code, and the high N ₃ bits of the boot serial number converted into binary numbers are shifted to the right by N ₄ bits to obtain the first intermediate verification code. Two intermediate verification codes. Preferably, N ₂ and N ₄ have the same number of digits.

In step S303, the first intermediate verification code and the second intermediate verification code are bitwise ORed to obtain a third intermediate verification code.

Step S304, take a plurality of information code segments in the third intermediate verification code, such as the A'-H' bit, the B'-G' bit, the I'-R' bit of the third intermediate verification code, and generate multiple information code segments. The CRC check code of each information code segment is arranged in the order of the information code segment to generate the power-on password. The method for generating the CRC check code of the information code segment can be in the form of checking the low byte table of the CRC check, and the CRC check code can also be obtained by other methods known in the prior art, which will not be repeated here.

Similarly, generate an authentication password by following the steps below.

After the first controller and the second controller are powered on again, the first controller transmits the boot serial number to the second controller. The second controller converts the received boot serial number into a binary number. The second controller shifts the low N ₁ bits of the boot serial number to the left by N ₂ bits to obtain the first intermediate verification code, and shifts the high N ₃ bits of the boot serial number to the right by N ₄ bits to obtain the second intermediate verification code. Preferably, N ₂ and N ₄ have the same number of digits. The third intermediate verification code is obtained by bitwise ORing the first intermediate verification code and the second intermediate verification code. Take multiple information code segments in the third intermediate verification code, if it is consistent with the server, take the A'-H' bits, B'-G' bits, I'-R' bits in the third intermediate verification code Bit, generate the CRC check codes of multiple information code segments, arrange the CRC check codes in the order of the information code segments to generate the check password, and the method of generating the CRC check codes of the information code segments can also be used to check the low CRC check code. In the form of a byte table, the CRC check code can also be obtained by other methods known in the prior art, which will not be repeated here. The power-on password is stored in the second controller, and the obtained verification password is compared with the power-on password to obtain whether the two match. If it matches, the second controller outputs a power-on instruction, and controls the unit to operate according to the temperature point, humidity point and control mode set by the second controller.
