Description

Technical Field

[0001] The present application relates to the field of computer software technology, and in particular to a method and system for user registration under a limited number of conditions. Background Art

[0002] In the application of various scientific and technological products, user registration is the first step for users to use a product or software. Only after registration can user operations and related information be retained in the product or software. As time goes by, users will retain more and more relevant information and data in the process of using products or software, occupying a certain amount of memory space. For the sake of lightweight design, some mobile or portable devices often have limited storage space and can accommodate a limited number of users. When the maximum number is exceeded, new users cannot be registered, which affects the registration of users to be registered and the use of corresponding devices. New users can only be registered after deleting existing users, and existing users often carry a large amount of user information. Direct deletion will lose user information. In addition, for the current users to be registered, they are often important users at the moment. If they are unable to register or need to wait to delete some users to make room for the current user to register, they often have to wait for a certain period of time, which also has a negative impact on the user experience. Therefore, how to quickly and conveniently ensure the successful registration of current users under limited quantity is an urgent problem to be solved.

[0003] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0054] The following will be combined with the implementation methods of this application to clearly and completely describe the technical solutions in the implementation methods of this application. Obviously, the described implementation methods are only part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] It should be understood that the terms used in this specification of the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present application. As used in the specification of the embodiments of the present application and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0057] In lightweight devices, in order to reduce the size of the device or the production cost, it is necessary to retain as much valid data as possible under limited memory conditions to prevent invalid data from occupying storage space for a long time. For example, the information of temporary users needs to be deleted in time, while the information of long-term users needs to be retained. In addition, the current user, that is, the user who needs to use the device at the moment, needs to be able to quickly register and display as the current user when using it. In the prior art, it takes a long time to register a new user, and if some invalid users are not clear, they will occupy the storage space of the device, which is not conducive to user management. For example, a blood pressure measurement activity launched by a community health hospital uses a blood pressure measuring instrument. In order to make the instrument light and low in cost, the data storage space of the instrument is limited, and the number of users that can be registered is also limited. The rapid registration or use of all personnel who meet the following conditions is required: some people in the community need to measure their blood pressure regularly, some people only measure it occasionally, and some only measure it once. How to ensure that the relevant information of long-term users is always saved, and the users who use it only once are cleared in time, and to ensure that new users can be quickly registered or the user information of the user end associated with the device can be quickly imported into the device to avoid memory fullness is the current problem.

[0058] In order to store more valid information of users and quickly register users, the first aspect of the present application is to provide a method for user registration under a limited number of conditions, such as Figure 1 As shown, the following steps are included:

[0059] S1. Set the maximum number of users M and the threshold value N according to the usage scenario, where M ≥ N;

[0060] S2. Determine the registration method and based on the number of existing users M a , the demarcation value N and the user attributes determine the user information of the user to be registered;

[0061] S3, completing the user information of the user to be registered, completing the registration and pushing it as the current user;

[0062] The demarcation value N is used to distinguish the user attributes, and the user attributes include formal users and temporary users;

[0063] The registration method includes device-side registration and user-side registration.

[0064] Furthermore, it is necessary to first set the maximum number of users M of the device and the demarcation value N between temporary users and formal users. The demarcation value N changes dynamically. It is also necessary to set a form for user information, as shown in Table 1. User information includes: serial number, user ID, user name, registration time, usage data, telephone number, etc. Among them, the serial number changes dynamically and is automatically sorted according to the registration date. For example, if there are 20 users at present, the original user information of No. 20 is deleted, and the serial number in the original user information of No. 21 is automatically changed, and the serial number is changed to 20. The other user information of the user remains unchanged.

[0066]

[0067]

[0068] Specifically, step S2, determine the registration method, and according to the number of existing users M a , the demarcation value N and the user attributes determine the information of the user to be registered, including the following steps:

[0069] S21, determining that the registration method is the device-side registration;

[0070] S22, based on the number of existing users M a and the demarcation value N to determine the serial number M of the user to be registered b and the user attributes, the serial number M of the user to be registered b ≤M;

[0071] S23. Obtain the user ID of the user to be registered and record the registration time.

[0072] Specifically, step S22, according to the number of existing users M a and the demarcation value N to determine the serial number M of the user to be registered b and properties, including:

[0073] S221, determining the number of existing users M a and the demarcation value N, so as to determine the user attribute of the user to be registered;

[0074] S222: Based on the number of existing users M a Calculate the serial number M of the user to be registered b , M b =M a +1.

[0075] Specifically, Figure 2 and 3 As shown, step S221, the determination of the number of existing users M aand the size of the demarcation value N to determine the user attributes of the user to be registered, including:

[0076] When M a <N, the attribute of the user to be registered is set to the formal user or temporary user;

[0077] When M a =N, then the user attribute of the user to be registered is set as a temporary user;

[0078] like Figure 2 As shown, when M a =N+1, deleting the existing temporary user, setting the user attribute of the user to be registered as a temporary user, and replacing the position of the existing temporary user;

[0079] Or, if Figure 3 As shown, when M a = N + 1, the user attribute of the temporary user is modified to a formal user, and the user attribute of the user to be registered is set to the temporary user, until the number of existing users is M a = Maximum number of users M.

[0080] Specifically, step S23, obtaining the user ID of the user to be registered, includes:

[0081] S231, obtaining at least one of the identity card and passport of the user to be registered as the user ID;

[0082] or S232, automatically generating a unique symbol composed of letters, symbols, and numbers as the user ID;

[0083] The user ID is used to confirm whether the user to be registered exists in the existing user information.

[0084] Specifically, the user information includes the user ID, the serial number, the user name, the registration date, the user attributes, and the login password;

[0085] The serial number is dynamically changed and is sorted according to the registration date; the dynamic change refers to deleting a serial number M c After the registered user, the original serial number is M cThe serial numbers of the registered users after the registered user are automatically filled in sequence. The serial numbers change dynamically. For example, there are 21 users in total currently, and the original user information of No. 20 is deleted. The serial number in the original user information of No. 21 is automatically filled, and the serial number is changed to 20, and the other user information of the user remains unchanged. The operation of deleting users can be manual deletion, or automatic deletion under certain conditions can be set, such as automatically deleting user information of users who have only been used once within a preset time, or automatically deleting user information of temporary users within a preset time. The setting of dynamic change of serial numbers is used to quickly determine how to set the user attributes of the users to be registered based on the maximum number of users M and the delimiter value N.

[0086] For example, in one embodiment, the maximum number of users M of the blood pressure monitor is set to 100, and the delimiter value N changes dynamically from 1 to 100. The user information is set to include: user name, registration time, usage data, and telephone number. The initial delimiter value N0=20 is set, which means that 20 formal users and 1 to 80 temporary users can be registered. When registering a new user, it is first necessary to determine whether the user ID of the new user exists in the existing user information. If so, the user ID is directly set as the current user without registration. If the current user ID does not overlap with the user ID of the existing user information, the user needs to be registered.

[0087] When the first user is registered, there are already M users a = 0, and the delimiter value N0 = 20. The serial number of the first registered user is 1, and the user attributes can be set as a formal user or a temporary user. The user attributes are set manually by the user.

[0088] When registering the 2nd to 20th user, the number of existing users is M a <N, the user attributes can be freely set as a formal user or a temporary user.

[0089] When the number of existing users M a =N0=20, the user attributes of the 21st user are automatically set to a temporary user.

[0090] When M a =N0+1=21, then there is at least one temporary user, assuming the sequence number of the 21st user is M 21 , there are several options when registering the 22nd user:

[0091] The first is the static adjustment method: Figure 2 As shown, N0=20 remains unchanged, the attribute of the 22nd user is automatically set to a temporary user, and the serial number is automatically generated as M 21+1, and the 23rd to 100th users can be set later, and the subsequent new users are automatically set as temporary users. In order of registration time, a total of 20 formal users and 80 temporary users can be registered. When the total number of users reaches 100, it will prompt "Registered users are full, please delete infrequent users before registering new users." You need to manually adjust the delimiter value N1 to any value from 21 to 100 to select user attributes when registering a new user.

[0092] The second is the dynamic adjustment method: Figure 3 As shown, first determine whether there is a temporary user. If so, the user attribute of the 22nd user is automatically set to a temporary user, delete the user information of the original temporary user, and automatically generate the serial number of the 22nd user as M 21 , replace the original temporary user with a new temporary user, obtain the user ID, record the registration time, and after completing other information in the user information, push the temporary user as the current user.

[0093] In the dynamic adjustment method, there is only one temporary user, and each newly added temporary user will replace the existing temporary user and become the current user, which can ensure quick registration without waiting when there is only one current user. However, the disadvantage is that if there are multiple new users to be registered, the user information of multiple temporary users cannot be retained at the same time. The solution is to dynamically adjust the demarcation value N or user attributes. Dynamic means automatically adjusting the demarcation value N or user attributes.

[0094] Specifically, in one embodiment, for example, a dynamic adjustment method is adopted, when the 22nd user is registered, the user attribute of the existing temporary user is automatically or manually modified to a formal user, and the demarcation value N is automatically adjusted to 21, and so on, 100 formal users can be set in sequence. Automatic adjustment is faster and more convenient, without waiting.

[0095] In another embodiment, step S2, determine the registration method, and according to the number of existing users M a , the demarcation value N and the user attributes determine the information of the user to be registered, and further comprises the following steps:

[0096] S24, determining that the registration method is registration of the user terminal, and obtaining the user information of the user terminal;

[0097] S25. Check whether the user ID in the acquired user information exists in the existing user information:

[0098] If it exists, call the existing user information and push it as the current user;

[0099] If it does not exist, register the user according to the method of S21-S23.

[0100] Specifically, in S24, obtaining the user information of the user terminal refers to importing the user information in the user terminal into the device terminal, which can be imported through Bluetooth connection, wireless network connection, wired network connection, etc. First, it is determined whether the user ID of the user terminal exists in the device terminal. If it does, the user information is directly called and pushed as the current user through the user ID. If it does not exist, it means that there is no such user in the device terminal, and the user needs to be re-registered on the device terminal. The user registration method is as described above.

[0101] Specifically, Figure 4 As shown, the second aspect of the present application is to provide a system for user registration under a limited number of conditions, comprising a device end 20 and a user end 10, wherein the device end 20 obtains user information of the user end 10 from the user end 10;

[0102] The device end 20 includes:

[0103] A setting module 21, used to set the maximum number of users M and the threshold value N according to the usage scenario, where M≥N;

[0104] The registration module 22 determines the registration method and determines the number of existing users M. a , the demarcation value N and the user attributes determine the information of the user to be registered;

[0105] The user management module 23 completes the user information of the user to be registered, completes the registration and pushes it as the current user;

[0106] The demarcation value N is used to distinguish the user attributes, and the user attributes include formal users and temporary users;

[0107] The registration method includes device-side registration and user-side registration.

[0108] Specifically, the device side can obtain the user information of the user side through any of the following methods: Bluetooth connection, wireless network connection and wired network connection. The data structure of the user information of the user side and the device side is consistent, and the structure of the user information form is consistent, including serial number, user ID, user name, registration time, usage data, telephone number, etc. Among them, the user IDs share a cloud database or share the same set of naming rules to make any user ID unique, such as automatically generating a unique identification code formed by a combination of numbers, letters and numbers as the user ID. Or the user ID of the user side is regenerated when it is imported into the device side to ensure that the user ID on the same device side is not repeated, but this method does not use the underlying database shared by multiple device sides to ensure that the user ID is not repeated. At the same time, the user information on the device side can also be updated to the user side through the cloud database, which is convenient for a single user to view.

[0109] In one embodiment, for example, the device end is a blood pressure measuring instrument, and the user end is a corresponding blood pressure measuring APP or a corresponding website. The user information in the APP can be imported into the blood pressure measuring instrument through any one of Bluetooth connection, wireless network connection and wired network connection.

[0110] A third aspect of the present application is to provide a storage medium, which is a non-transitory computer-readable storage medium and stores a program of a method for user registration under a limited number of conditions, and when the program is executed by a processor, the following steps are implemented:

[0111] S1. Set the maximum number of users M and the threshold value N according to the usage scenario, where M ≥ N;

[0112] S2. Determine the registration method and based on the number of existing users M a , the demarcation value N and the user attributes determine the information of the user to be registered;

[0113] S3, completing the user information of the user to be registered, completing the registration and pushing it as the current user;

[0114] The demarcation value N is used to distinguish the user attributes, and the user attributes include formal users and temporary users;

[0115] The registration method includes device-side registration and user-side registration.

[0116] In summary, the present application provides a method for user registration under a limited number of conditions, comprising the following steps: setting a maximum number of users M and a threshold value N according to a usage scenario, where M ≥ N; determining a registration method, and according to the number of existing users M a , the demarcation value N and user attributes determine the information of the user to be registered; complete the user information of the user to be registered, complete the registration and push it as the current user; wherein, the demarcation value N is used to distinguish the user attributes, and the user attributes include formal users and temporary users; the registration method includes device-side registration and user-side registration. The dynamic registration method of the present application solves the problems of long waiting time for user registration and cumbersome registration under limited quantity, and provides a convenient and efficient user registration method.
