Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioners, and in particular to a detection remote controller with a dynamic password function and a control method thereof. Background Art
[0002] With the increasing popularity and sales of large-scale air conditioners, production volumes, engineering workloads, and user base are increasing, placing ever-higher demands on the stability and safety of these units. During operation, for various reasons (such as unit failures, service agreement expiration and renewal, operational errors, or operational safety issues), the unit may require password-based control via an air conditioner test remote control. Traditional air conditioner test remote controls typically use fixed passwords, which are convenient but have drawbacks such as low security and susceptibility to interception or tampering by unauthorized devices, resulting in unreliable test data.
[0003] Therefore, based on the above technical problems, this application proposes a control method for detecting a remote control with a dynamic password function that can periodically update passwords and has high security. Summary of the Invention
[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a control method for detecting a remote controller with a dynamic password function, which can periodically update passwords and has high security.
[0005] In order to achieve the above-mentioned purpose, the present invention provides a control method for detecting a remote controller with a dynamic password function: Step 1: Make the detection remote control randomly generate a new control password; Step 2: Determine whether the remote controller of the air conditioner satisfies the preset condition 1 or the preset condition 2; Step 3: When the determination result is no, return to step 1 and regenerate a random control password; conversely, when the determination result is yes, the detection remote controller stores the generated control password in the storage module; Step 4: Instruct the main program for detecting the remote control to calculate the control password in the storage module; Step 5 repeats step 2 to determine whether the control remote controller of the air conditioner meets preset condition 1 or preset condition 2; If the determination result in step 6 is negative, the process returns to step 4 and causes the main program of the remote control detection to recalculate the control password in the storage module. If the determination result in step 6 is positive, the process returns to step 3 and stores the control password generated by the remote control detection in the storage module. Step 7 counts the number of times the control password is displayed in step 6, and determines whether the relevant count value exceeds a preset value; In step 8, when the determination result is no, return to step 4 and store the control password generated by the detection remote control in the storage module; otherwise, when the determination result is yes, return to step 1 and let the detection remote control randomly generate a new control password.
[0006] Furthermore, the preset condition 1 is whether the number of power failures of the remote controller of the air conditioner is greater than a preset number, and the preset condition 2 is whether the cumulative usage time of the remote controller is greater than a preset number of days.
[0007] Furthermore, when the air conditioner is in the on state and its electronically controlled operating mode is consistent with the mode of the detection remote control, the air conditioner receives the control signal of the detection remote control; conversely, when the air conditioner is in the standby state and its electronically controlled operating mode is inconsistent with the mode of the detection remote control, the air conditioner does not receive the control signal of the detection remote control.
[0008] Furthermore, the detection remote control includes a dynamic password generation module, a communication module, a processor module, a storage module and an address coding module. The dynamic password generation module is used to randomly generate a new control password. The communication module is used to establish a communication connection with the air-conditioning equipment. The storage module stores the main program that drives the processor module to run. The address coding module is used to store multiple groups of address codes, and each address code corresponds to a specific test mode.
[0009] Furthermore, the storage module is preferably an electrically erasable programmable read-only memory.
[0010] Furthermore, the detection remote controller only sends a control signal for changing the control password to the air conditioner.
[0011] The present invention adopts the above-mentioned solution, and its beneficial effects are: Unlike traditional fixed static passwords, which are easy to be stolen or cracked, thus leading to illegal control of the device, in the detection remote control of this embodiment, different dynamic passwords are used periodically, which greatly increases the difficulty for attackers to obtain valid passwords, effectively preventing unauthorized personnel from operating the air-conditioning equipment in related places, and ensuring the security of the air-conditioning during the detection process and the detection results. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a schematic diagram of the interaction of detecting the remote control in this embodiment.
[0013] Figure 2 This is a control flow chart for detecting the remote controller in this embodiment. DETAILED DESCRIPTION
[0014] To facilitate understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the present disclosure.
[0015] See attached Figure 2 As shown, in this embodiment, a control method for detecting a remote controller with a dynamic password function is provided: Step 1: Make the detection remote control randomly generate a new control password; Step 2 determines whether the remote control of the air conditioner satisfies preset condition 1 or preset condition 2, wherein preset condition 1 is whether the number of power failures of the remote control of the air conditioner is greater than 5 times (preset number of times), and preset condition 2 is whether the cumulative usage time of the remote control is greater than 60 days (preset number of days); Specifically, unlike traditional fixed static passwords that are easily stolen or cracked, resulting in illegal control of the equipment, in this embodiment, the security of the control password is determined based on multiple preset conditions, which can effectively prevent unauthorized personnel from operating the air-conditioning equipment in related places, thereby ensuring the security of the air-conditioning during the detection process and the detection results; secondly, when the current password of the control remote control becomes invalid due to power failure or standby timeout, the user needs to provide feedback to the administrator based on the flashing information on the air-conditioning LCD screen. The administrator will determine based on the needs whether to provide a new password to the user and restore the operation of the control remote control.
[0016] Step 3: When the determination result is no, return to step 1 and regenerate a random control password; conversely, when the determination result is yes, the detection remote controller stores the generated control password in the storage module; Step 4: The main program for detecting the remote controller calculates the control password in the storage module, thereby replacing the original control password of the air conditioner to improve security. Step 5 repeats step 2 to determine whether the control remote controller of the air conditioner meets preset condition 1 or preset condition 2; If the result of step 6 is negative, the process returns to step 4 and causes the main program of the remote control detection to recalculate the control password in the storage module; otherwise, if the result of step 6 is positive, the process returns to step 3 and stores the control password generated by the remote control detection in the storage module; Step 7 counts the number of times the control password is displayed in step 6, and determines whether the relevant count value exceeds a preset value; In step 8, when the judgment result is no, return to step 4 and store the control password generated by the detection remote control in the storage module; conversely, when the judgment result is yes, return to step 1 and let the detection remote control randomly generate a new control password. By periodically changing the dynamic password, the safety of the air-conditioning place can be improved.
[0017] Furthermore, when the air conditioner is in the on state and its electronic control operation mode is consistent with the mode of the detection remote control, the air conditioner receives the control signal of the detection remote control; conversely, when the air conditioner is in the standby state and its electronic control operation mode is inconsistent with the mode operated by the detection remote control, the air conditioner does not receive the control signal of the detection remote control, that is, when the air conditioner is turned on and runs in cooling mode, the air conditioner only receives data for the cooling test mode; when the air conditioner is turned on and runs in heating mode, the air conditioner only receives data for the heating test mode; in addition, when the air conditioner enters the relevant test mode, it exits the test mode when it receives any button operation electronic control or remote control code from the detection remote control or the control remote control.
[0018] In this embodiment, see the attached Figure 1 As shown, the detection remote control includes a dynamic password generation module, a communication module, a processor module, a storage module and an address coding module. The dynamic password generation module is used to randomly generate a new control password. The communication module is used to establish a communication connection with the air-conditioning equipment. The storage module stores the main program that drives the processor module to run. The address coding module is used to store multiple groups of address codes, and each address code corresponds to a specific test mode. Among them, the correspondence between the air-conditioning related test mode and the data set by the detection remote control requires querying the address coding comparison table, thereby ensuring the safety of the air-conditioning during the detection process and the accuracy of the detection results.
[0019] Furthermore, the storage module is preferably a powered erasable programmable read-only memory. The powered erasable programmable read-only memory can store data for a long time after power failure and does not require continuous power supply. This can better ensure the normal operation of the detection remote control and extend the service life of the detection remote control.
[0020] Furthermore, the detection remote control only sends a control signal for changing the control password to the air conditioner, and does not perform functions such as power on and off, mode switching, etc. Through independent function design, the mixed use of the control remote control and the detection remote control can be avoided, thereby improving the independence of the detection remote control in this embodiment and relatively reducing the production cost of the detection remote control.
[0021] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art who, without departing from the scope of the technical solution of the present invention, utilizes the technical content disclosed above to make more possible changes and modifications to the technical solution of the present invention, or modifications are all equivalent embodiments of the present invention. Therefore, any equivalent and equivalent changes made in accordance with the ideas of the present invention without departing from the content of the technical solution of the present invention should be included in the scope of protection of the present invention.
