Description

Technical Field

[0001] The present invention relates to the technical field of equipment management, and in particular to a child lock management system and system based on data technology. Background Art

[0002] Child lock refers to a safety feature or mechanism used to prevent potential dangers caused by children's curiosity or misoperation. It is different from a lock in the ordinary sense. Its characteristic is that it takes into account the needs of "difficult for children to open, but easy for adults to open". The adult group here usually refers to unspecified adult individuals, unless in some specific usage scenarios, it will be restricted to family members, members, etc. Data technology can be understood as a series of technical methods and tools for processing, managing and analyzing data. Therefore, combining data technology to manage child locks can effectively prevent children from coming into contact with potentially dangerous items or environments due to curiosity or unintentional operation, thereby reducing the occurrence of accidental injuries.

[0003] Patent application No. 201610290136.X and publication No. CN 105808995 A disclose a password prompt method, device and terminal, which include: receiving a password prompt instruction, the password prompt instruction is used to instruct the terminal to display the historical passwords used by the current account, the historical passwords used by the current account refer to the passwords that have been set for the current account except the password currently in use; display the historical passwords used by the current account to provide a password input prompt. This patent displays the historical passwords used for password input prompts, so that the user will no longer enter the historical password after seeing the historical password, thereby effectively reducing the probability of the user entering the wrong password, avoiding the account being locked and unable to be used normally due to the user entering the wrong password, and improving the user experience of the terminal. However, this patent is only used to display the historical passwords used;

[0004] Patent application No. 201810001440.7 and authorization announcement No. CN 108229134 B disclose a password prompt method and electronic device, the method comprising: responding to a power-on command; initializing a non-volatile memory of an electronic device, wherein the non-volatile memory stores at least operating system data that needs to be loaded onto the volatile memory; when the non-volatile memory is provided with a password lock, a first prompt message for prompting a user to enter a password is displayed on the screen of the electronic device, and a second prompt message for prompting a user to enter a password is outputted through a first component of the electronic device. However, it is only used in scenarios where the user cannot remember the proprietary password and does not involve a child lock.

[0005] At present, the method of child lock management is mainly physical locking mechanism, which is to prevent children from opening household appliances, medical equipment, medicine boxes, etc. by using physical devices such as child safety locks, door locks, and lid locks. This method is easy to be cracked by children due to its relatively simple management mode and simple operation, and it cannot be applied to all types of equipment, resulting in the inability to effectively ensure the safety of children. In addition, the technology for child lock password unlocking is relatively mature. The common ones are: unlocking by electronic identification, unlocking by complex action combination, unlocking by action requiring greater force, unlocking by hidden action, and unlocking by password; second, the solution of unlocking by electronic identification, such as NFC matching, fingerprint recognition, Bluetooth matching, etc., is relatively expensive, and is usually restricted to a single user, and other adults cannot use it, rather than just prohibiting children from using it; third, the solution of unlocking by complex action combination or by action requiring greater force, while restricting children from opening the device, also brings inconvenience to adult users. However, there are problems with the above unlocking schemes when used for child lock purposes:

[0006] (1) When the unlocking passwords of different devices, such as the number of consecutive draws and presses, are the same, adult users need to remember them. However, once children know them, they can easily unlock the device, making the solution ineffective. For example, if a certain type of device generally uses the method of pressing a button five times in a row to turn it on, then once children know the password "5", they can open the child locks of a large number of similar products;

[0007] (2) If different unlocking passwords are set for devices of different manufacturers, specifications, and models in order to circumvent problem (1), adult users also need to remember the corresponding passwords, which affects the operation experience. If it is a public device, it also involves the operation of password information transmission, making the entire application more complicated.

[0008] Therefore, due to the above problems, the current control effect of child lock management is relatively poor, so there is an urgent need for a solution that can improve the precise control effect of child lock management. Summary of the invention

[0163] In order to further understand the implementation process of the above-mentioned child lock management system based on data technology, the following two application scenarios are further explained.

[0164] For application scenario 1, please refer to Figure 3-5FIG. 1 is a schematic diagram of the structure of a microwave oven device provided by the present invention, wherein: Figure 3 A schematic diagram of the appearance of a microwave oven. Figure 4 This is a schematic diagram of the password prompt area and button area. Figure 5 This is a schematic diagram of the buckle design on the back of the microwave oven panel. Specifically, for microwave ovens sold in China, in order to prevent children under 5 years old from getting burned when taking out hot food from the oven, a child lock is added to the microwave oven. The specific implementation process is as follows:

[0165] Prompt information design: Considering that most 5-year-old children in China have not learned English arithmetic, when the password prompt information is designed as "nine minus five" and the corresponding password is "4", 5-year-old children generally cannot understand it.

[0166] The prompt message says: In the "Password Hint" area, put a label containing the words "nine minus five"

[0167] Password input: After the adult user understands that the password is "4", he / she presses the button 4 times in succession. Children cannot enter the password correctly because they cannot understand the password prompt.

[0168] Switch mechanism: After the control circuit board receives the information of four consecutive presses from the button, it compares it with the password "4" stored in advance. If the two match, the buckle is tightened so that it is no longer stuck on the main body. The microwave door can be opened to take out the heated food.

[0169] For application scenario 2, please refer to Figure 6-7 FIG. 1 is a schematic diagram of the structure of a household medicine box provided by the present invention, wherein: Figure 6 This is a schematic diagram of the appearance of a household medicine cabinet. Figure 7 This is a schematic diagram of the password prompt and password input of a household medicine box. For example, for household medicine boxes sold in China, a child lock is added to prevent children under 3 years old from opening the medicine box and touching the medicine. The specific implementation process is as follows:

[0170] Prompt information design: Taking into account the Chinese and English proficiency of 3-year-old children in China, the password prompt information is set to "Quail is a kind of", and the corresponding password is "bird".

[0171] The prompt message shows: In the "Password Hint" area, put a label containing the words "Quail is a kind of"

[0172] Password input: After the adult user understands that the password is "bird", he or she turns the password dial to display the letters "bird". A 3-year-old child usually does not know "quail" or the English spelling of bird "bird", so he or she cannot turn the password dial to the correct position.

[0173] Switch mechanism: When the password dial is in the correct position, the lock buckle mechanism is released and the medicine box can be opened. If the password dial is incorrect, the buckle will be tightened normally and cannot be opened.

[0174] The embodiment of the present invention can set a more complex and difficult-to-guess password by creating password prompt information for the smart child lock, thereby improving the security of the smart child lock, and at the same time guiding the user to enter the password correctly, reducing the difficulty of unlocking due to forgotten passwords, and displaying the password prompt information of the smart child lock in the password prompt area can provide users with a more natural and intuitive interaction method, thereby improving the affinity and ease of use of the product; the embodiment of the present invention performs the unlocking process of the smart child lock after comparing the input child lock password with the preset password for consistency, and can accurately determine whether the password input by the user matches the preset password, and can ensure that only verified passwords can trigger unlocking, thereby enhancing the security of the system, and at the same time reducing the potential risks of the device to children. Therefore, the present invention can improve the precise control effect of child lock management.

[0180] When the matching degree is not greater than a preset threshold, a notification of a failed unlocking of the smart child lock is displayed in the password prompt area; when the matching degree is greater than the preset threshold, the voice password is converted into an electrical signal of the smart child lock based on the communication module, and the electrical signal is converted into an unlocking instruction of the smart child lock using the control module, and then the unlocking process of the smart child lock is executed.
