Technical Field

[0002] MQTT (Message Queuing Telemetry Transport) is an Internet of Things transmission protocol developed by IBM. It uses a lightweight subscription / publishing model for message transmission. MQTT has been specially optimized for low-bandwidth, low-computing, and unstable network environments. It is suitable for message push targeting embedded smart terminals and mobile terminals, and can effectively save terminal power consumption and traffic. However, in the prior art, when using an MQTT message server for message push, users are generally required to set message information subscription permissions for each object. Therefore, when the MQTT message server pushes messages, it needs to query the message information subscription permissions of each object. When there are many objects, the MQTT message server needs to traverse each object in turn to determine whether the user has information subscription permissions, which seriously reduces the efficiency of information push.

The various embodiments herein are described in a progressive manner, with each embodiment focusing on the differences from the other embodiments. Reference can be made to the common and similar parts between the various embodiments. For structures, products, etc. disclosed in the embodiments, the description is relatively simple because they correspond to the parts disclosed in the embodiments. For relevant parts, refer to the method description.

[0037] like Figure 1 As shown, Figure 1The present invention provides a flowchart of an information push method according to an embodiment of the present invention. The information push method according to an embodiment of the present invention can be executed by an information push device, which can be implemented by software and / or hardware. The information push device can be composed of two or more physical entities or a single physical entity. For example, the information push device can be a server or a host computer. In this embodiment, the information push device is described as a message server, and the message server is an MQTT message server. The information push method provided by the embodiment of the present invention includes the following steps:

[0038] Step 101: Receive the device information of each device pushed by the message parsing service in real time and save the device information.

[0039] In this embodiment, the MQTT message server pre-establishes a communication connection with the message parsing service, which then receives, in real time, the device information for each device pushed by the message parsing service. The message parsing service pre-establishes a communication connection with each device, receives and parses messages pushed by each device in real time, and obtains device information corresponding to each device. For example, this device information may include hardware information and the device's current status. After obtaining the device information, the message parsing service pushes the device information to the MQTT message server in real time. MQTT stores the device information for each device, either locally on the MQTT message server or in a database.

[0040] Step 102: In response to a connection request from the user terminal, connect to the user terminal and obtain user information of the user terminal.

[0041] In this embodiment, when a user needs to obtain device information, they can log in to their account through the application on the user terminal and control the user terminal to send a connection request to the MQTT message server through the application. The connection request is used to request a connection with the MQTT message server. After receiving the connection request, the MQTT message server responds to the connection request and establishes a communication connection with the user terminal that initiated the connection request. The MQTT message server then obtains the corresponding user information from the user terminal, that is, relevant information about the user currently using the user terminal. For example, the user information may be the user's account information.

[0042] Step 103: In response to the information acquisition request of the user terminal, query the database for information subscription rights corresponding to the user information; the information subscription rights are pre-stored in the database and updated in real time, and the information subscription rights of each user information include device information corresponding to devices in at least one granularity range, and the granularity range includes each device or all devices within a spatial range. All devices under the spatial range are pre-bound to the number corresponding to the spatial range, and the spatial range is pre-divided, and each spatial range corresponds to a number.

[0043] After the MQTT message server is connected to the user terminal, the user terminal can initiate an information acquisition request to the MQTT message server, where the information acquisition request is used to request the device information stored by the MQTT message server. After receiving the information acquisition request, the MQTT message server responds to the information acquisition request. First, the MQTT message server queries the database for the information subscription permissions corresponding to the user information on the user terminal. In this embodiment, the information subscription permissions corresponding to each user information are pre-set by the administrator and stored in the database, and the information subscription permissions are updated in real time based on the administrator's modifications.

[0044] It should be noted that, in this embodiment, the information subscription rights corresponding to the user information include device information corresponding to devices in at least one granularity range. The granularity range is used to characterize the number of devices to which the device information that can be obtained by the user terminal corresponding to the user information belongs. In this embodiment, the granularity range includes each device or all devices within a spatial range, wherein the spatial range can be divided in advance. For example, the administrator can divide a room or a house into a spatial range in advance, etc. The specific division method can be set according to actual needs, and this embodiment does not specifically limit it. After dividing a spatial range, the administrator needs to set a unique number for the spatial range, and bind all devices within the spatial range to the number corresponding to the spatial range. For example, when the spatial range is a residence, the device numbers of the television, air conditioner, water heater, washing machine, refrigerator and other equipment in the residence can be bound to the number of the spatial range, so that all devices within the spatial range can be found later according to the number of the spatial range.

[0045] When the granularity of the information subscription rights corresponding to user information is per device, the administrator can pre-set the information subscription rights for the user corresponding to the user information for each device, such as information subscription rights for air conditioner device information or television device information, and grant the corresponding information subscription rights to the user. When the granularity of the information subscription rights corresponding to user information is spatial, the administrator can pre-set the spatial scope for which the user corresponding to the user information has information subscription rights, such as information subscription rights for a residence or a classroom, and bind the user information to the spatial scope number, thereby granting the user information subscription rights for the device information corresponding to all devices within the spatial scope.

[0046] Step 104: When the granularity of the information subscription rights of the user information is per device, the target device for which the user terminal has information subscription rights is determined based on the information subscription rights, the target device information is determined based on the device information corresponding to the target device, and the target device information is pushed to the user terminal.

[0047] After the MQTT message server determines the information subscription rights corresponding to the user information, when the granularity of the information subscription rights of the user information is each device, the MQTT message server determines the target devices for which the user terminal has information subscription rights based on the information subscription rights, obtains the device information corresponding to the target device, and determines the target device information to be pushed based on the device information corresponding to the target device, and then pushes the target device information to the user terminal, which then visualizes the target device information, so that the user can view the target device information through the user terminal.

[0048] Step 105. When the granularity range of the information subscription rights of the user information is all devices belonging to a spatial range, determine the target spatial range in which the user terminal has the information subscription rights according to the information subscription rights, determine the target device within the target spatial range, determine the target device information according to the device information corresponding to the target device, and push the target device information to the user terminal.

[0049] When the MQTT message server determines that the granularity of the user's information subscription rights is a spatial range, the MQTT message server can determine the target spatial range for which the user terminal has information subscription rights based on the user's information subscription rights, and determine the bound target devices based on the target spatial range number, that is, all devices within the target spatial range. The MQTT message server then obtains the device information corresponding to the target device, determines the target device information to be pushed based on the device information corresponding to the target device, and further pushes the target device information to the user terminal for display.

[0050] The embodiment of the present application provides a kind of information push method, and the granularity range of information subscription right corresponding to each user information in the embodiment of the present application includes each device or all devices belonging to a space range.When the information subscription right corresponding to user information is a space range, only need to determine the target device that is bound in advance with the space range, and the target device information corresponding to target device is pushed to the user terminal corresponding to user information, it is not necessary to traverse each object in turn to determine whether the user has information subscription right, improve the efficiency of information push, solve the technical problem that the information push efficiency of MQTT message server is low in prior art when pushing information.In addition, in the embodiment of the present application, administrator only needs to bind the number corresponding to space range with user information when setting information subscription right corresponding to user information, without binding device in space range with user information one by one, also improve the efficiency of administrator to configure information subscription right.

[0051] On the basis of the above embodiment, the device information of each device pushed by the message parsing service in real time is received in step 101, including:

[0052] Step 1011, receive the login information sent by the message parsing service, verify according to the login information, and obtain the information push right corresponding to the login information after verification, the information push right is stored in local and is bound with the login information of different message parsing services.

[0053] In the embodiment, the message parsing service will send login information to the MQTT message server before pushing information to the MQTT message server, and the login information is used to log in to the MQTT message server, for example, the login information includes the login account and login password of the message parsing service.The MQTT message server verifies the login information after receiving the login information, and determines whether the login information is correct.In one embodiment, the login information of all message parsing services can be saved in the MySQL warehouse, and the MQTT message server matches the received login information with the login information in the MySQL warehouse after receiving the login information, and if it can be matched, the verification is passed, otherwise it cannot be verified.

[0054] If the verification is passed, the MQTT message server obtains the corresponding information push right according to the login information, and the information push right is the right to push different messages to the MQTT message server, and the information push right in the embodiment can be set by the administrator in advance and stored in the MQTT message server, and the login information of different message parsing services is bound with different information push rights.

[0055] Step 1012: Determine the first device information that the message parsing service can push based on the information push permission.

[0056] After obtaining the information push permission, the MQTT message server can determine the first device information that the message parsing service can push based on the push permission.

[0057] Step 1013: Receive the first device information pushed by the message parsing service.

[0058] After determining the first device information that can be pushed by the message parsing service, the MQTT message server only receives the first device information pushed by the message parsing service, and can ignore or reject other device information pushed by the message parsing service.

[0059] As described above, in the embodiment of the present invention, the information push device can only receive the first device information pushed by the message parsing service according to the preset information push authority, thereby avoiding receiving too much invalid information and occupying too many resources, thereby improving resource utilization.

[0060] Based on the above embodiment, the user information further includes a role type.

[0061] In this embodiment, the user information also includes a role type, where the role type is used to characterize the identity of the user corresponding to the user information. For example, the role type can be an administrator, visitor, or operation and maintenance personnel, etc. The role type is applied for when the user registers or can be assigned by the administrator.

[0062] In step 104 and step 105, the target device information is determined based on the device information corresponding to the target device, and the target device information is pushed to the user terminal, including:

[0063] Step 1051: Determine the role type based on the user information, and determine the permission level based on the role type.

[0064] In one embodiment, after obtaining the device information of the target device, the MQTT message server will not directly push the device message of the target device to the corresponding user terminal, but will further determine the role type corresponding to the user information based on the user information of the user terminal. After determining the role type, it is also necessary to further determine the permission level corresponding to the role type, where different role types correspond to different permission levels. For example, the administrator corresponds to the highest level of permission, corresponding to the first permission level; the operation and maintenance personnel have the second highest permission level, corresponding to the second permission level; the visitor has the lowest permission level, corresponding to the third permission level. In this embodiment, the permission level limits the content of the device information of each target device that can be obtained by different role types.

[0065] Step 1052, according to the permission level, target sub-device information of which the user terminal has information subscription permission is determined from the device information corresponding to the target device. The device information of one device includes multiple sub-device information.

[0066] After determining the permission level corresponding to the user information, the MQTT message server can determine the target sub-device information of which the user terminal corresponding to the user information has information subscription permission from the device information corresponding to the target device according to the permission level. In the embodiment, the device information of one device includes multiple sub-device information, for example, the sub-device information of the target device includes hardware information, state information, network connection information and device identification information. For the administrator, the administrator can obtain all the sub-device information of the target device, that is, the target sub-device information includes all the sub-device information. For the operation and maintenance personnel, the operation and maintenance personnel can obtain the sub-device information of the target device as the hardware information, the state information and the network connection information, that is, the target sub-device information includes the hardware information, the state information and the network connection information. For the visitor, the visitor can only obtain the sub-device information of the target device as the state information, that is, the target sub-device information only includes the state information.

[0067] Step 1053, the target sub-information is taken as the target device information and is pushed to the user terminal.

[0068] After determining the target sub-device information of which the user terminal has information subscription permission, the target sub-information is taken as the target device information and is pushed to the corresponding user terminal for display.

[0069] In the above embodiment, when the information pushing device pushes the device information to the user terminal, the role type corresponding to the user terminal is determined according to the user information, the corresponding permission level is determined according to the role type, and the target sub-information pushed to the user terminal is determined according to the permission level. In the embodiment, by configuring the role type corresponding to different user information, the device sub-information that can be obtained by different user information can be flexibly configured, the flexibility of configuring the user permission is further improved, and the information security is improved to avoid information leakage.

[0070] On the basis of the above embodiment, before the target sub-information is taken as the target device information and is pushed to the user terminal, the following steps are further included:

[0071] Step 1054, it is determined whether the permission level is within a preset permission level range, and the preset permission level range includes at least one permission level.

[0072] In one embodiment, after determining the target sub-information, before using the target sub-information as target device information and pushing it to the user terminal, it is also necessary to determine whether the permission level corresponding to the user information is within the preset permission level range. The preset permission level range includes at least one permission level. Exemplarily, in one embodiment, the preset permission level range can be set to include a third permission level, that is, if the role type corresponding to the user information is a visitor, then the permission level of the user information is within the preset permission level range.

[0073] Step 1055: If yes, send a verification message to the target user terminal corresponding to the target user information, where the target user information is user information corresponding to the role type with the target authority level.

[0074] If the permission level is within the preset permission level range, the MQTT message server also needs to send a verification message to the target user terminal corresponding to the target user information, where the target user information is the user information corresponding to the role type with the permission level of the target permission level. For example, in this embodiment, the target permission level can be set to the first permission level, that is, the verification message is sent to the target user terminal whose user information is administrator. In addition, in this embodiment, the verification message is used to inquire whether it is allowed to push the target device information to the user terminal corresponding to the permission level within the preset permission level range.

[0075] Step 1056: Determine whether to push the target device information to the user terminal based on the verification pass message fed back by the monitored target user terminal. The verification pass message is generated when the target user terminal determines to push the target device information to the user terminal.

[0076] After the MQTT message server sends a verification message to the target user terminal, the target user terminal will respond to the verification message, for example, the target user terminal will display a confirmation box locally, and the confirmation box allows the administrator to confirm whether to allow the target device information to be pushed to the user terminal. If the administrator confirms, the target user terminal determines to push the target device information to the user terminal and feedbacks a verification pass message to the MQTT message server. The MQTT message server can then determine whether to push the target device information to the user terminal based on the verification pass message it monitors. In one embodiment, the MQTT message server can determine whether to push the target device information to the user terminal based on the number of verification pass messages it monitors within a preset time period.

[0077] On the basis of the above embodiment, determining whether to push the target device information to the user terminal according to the verification pass message fed back by the monitored target user terminal includes:

[0078] Step 10561: When the number of target user terminals that monitor the feedback verification pass message within the first preset time period exceeds a preset ratio, determine to push the target device information to the user terminal.

[0079] In one embodiment, after sending a verification message to a target user terminal, if the number of target user terminals that have monitored feedback verification pass messages within a first preset time period exceeds a preset ratio among all target user terminals, it is determined that the target device information is pushed to the user terminal. The first preset time period can be set according to actual needs, for example, it can be set to 3 minutes or 5 minutes, etc., which is not specifically limited in this embodiment. The preset ratio can also be set according to actual needs, for example, the preset ratio can be set to 50%. If the number of target user terminals that have monitored feedback verification pass messages within the first preset time period exceeds 50% (not rounded to an integer) of the number of all target user terminals, it is determined that the target device information is pushed to the user terminal.

[0080] Step 10562: When the number of target user terminals that receive feedback verification pass messages within the first preset time period is less than a preset ratio and greater than zero, if device information has been pushed to the user terminal corresponding to the user information in the past, determine to push the target device information to the user terminal.

[0081] When the number of target user terminals that have monitored feedback verification pass messages within the first preset time period is less than a preset ratio and greater than zero, it can be determined whether device information has been pushed to the user terminal corresponding to the user information in the past, thereby determining whether the user information has been trusted in the past. If device information has been pushed to the user terminal corresponding to the user information in the past, it means that the user information is a trusted user, and it can be determined that the target device information will be pushed to the user terminal. In other cases, it can be determined not to push the target device information to the user terminal. In one embodiment, the process of determining whether to push the target device information to the user terminal is as follows: Figure 2 shown.

[0082] Based on the above embodiment, the following further aspects are included:

[0083] Receive the permission modification instruction sent by the target user terminal.

[0084] A first spatial range corresponding to target user information of a target user terminal is determined, and the granularity range of information subscription authority is determined to be within the first spatial range, and the first user information whose authority level is less than the target authority level.

[0085] Determine the first target user information pointed to by the permission modification instruction.

[0086] The information subscription authority corresponding to the first target user information is modified in the database.

[0087] In one embodiment, for the target user corresponding to the target user information with the target permission level, the target user terminal can also be used to send a permission modification instruction to the MQTT message server to modify the granularity of the information subscription permission to the information subscription permission of the user information with a lower permission level within the same spatial range. Specifically, after the target user modifies the information subscription permission of the user information with a lower permission level on the target user terminal, the target user terminal sends a permission modification instruction to the MQTT message server. When the MQTT message server receives the permission modification instruction sent by the target user terminal, the MQTT message server determines the first spatial range that has the information subscription permission for the target user information of the target user terminal. After determining the first spatial range, it further determines that the granularity of the information subscription permission is within the first spatial range, and the first user information with a permission level less than the target permission level.

[0088] After determining the first user information, the first target user information pointed to by the permission modification instruction is further determined in the first user information, and then the information subscription permission corresponding to the first target user information can be modified in the database according to the permission modification instruction. It can be understood that in this embodiment, the granularity range of the information subscription permission is that users with the target permission level within the same spatial range can only modify the information subscription permission of user information with a lower permission level within the spatial range, and cannot modify the information subscription permission of user information in other spatial ranges. In addition, when the granularity range of the information subscription permission corresponding to the target user information is each device, the target user terminal cannot modify the subscription permission of other user information, and the MQTT message server can reject the permission modification instruction.

[0089] Based on the above embodiment, the database updates the information subscription rights in real time according to the addition or deletion of the information subscription rights. The method further includes:

[0090] 106. When it is detected that the information subscription authority is modified, new target device information that the user terminal can subscribe to is re-determined based on the modified information subscription authority, and permission modification information is generated at the same time.

[0091] 107. Push the new target device information and permission modification information to the user terminal.

[0092] In another embodiment, after the MQTT message server pushes the target device information to the user terminal, the MQTT message server will monitor the changes in the information subscription permissions in the database in real time. If the administrator modifies the information subscription permissions of the user information corresponding to the user terminal in the database, such as adding or deleting the information subscription permissions, the database will update the information subscription permissions in real time, and the MQTT message server can detect the changes in the information subscription permissions in the database. At this time, the MQTT message server will re-determine the new target device information that the user terminal can subscribe to based on the modified information subscription permissions, and generate permission modification information at the same time, and push the new target device information and permission modification information to the user terminal for display, where the permission modification information is used to prompt the user using the user terminal that the information subscription permissions have been modified.

[0093] As described above, before pushing target device information to a user terminal, the embodiment of the present invention will send a verification message to the target user terminal if the user terminal's authority level is within the preset authority level range. If the number of target user terminals that receive feedback verification pass messages exceeds a preset ratio within a first preset time period, or if device information has been pushed to the user terminal corresponding to the user information in the past, the target device information will be pushed to the user terminal. The embodiment of the present invention determines the target device information to be pushed to the user terminal only after querying the user terminal corresponding to the role type of the target authority level, thereby further improving information security and preventing device information from being obtained by untrusted users.

[0107] Based on the above embodiment, the message server 202 is specifically configured to, before sending the target sub-information as target device information to the user terminal 204, further:

[0108] Determine whether the authority level is within the preset authority level range, which includes at least one authority level; if so, send a verification message to the target user terminal 204 corresponding to the target user information, where the target user information is the user information corresponding to the role type with the target authority level; based on the verification pass message fed back by the monitored target user terminal 204, determine whether to push the target device information to the user terminal 204, and the verification pass message is generated by the target user terminal 204 when it determines to push the target device information to the user terminal 204.

[0109] Based on the above embodiment, the message server 202 is specifically used to determine to push the target device information to the user terminal 204 when the number of target user terminals 204 that have listened to the feedback verification pass message within the first preset time period exceeds a preset ratio; when the number of target user terminals 204 that have listened to the feedback verification pass message within the first preset time period is less than the preset ratio and greater than zero, if device information has been pushed to the user terminal 204 corresponding to the user information in history, it is determined to push the target device information to the user terminal 204.

[0111] Based on the above embodiment, the database is specifically used to update the information subscription rights in real time according to the addition or deletion of information subscription rights;

[0112] The message server 202 is also used to, when detecting that the information subscription authority has been modified, re-determine the new target device information that the user terminal can subscribe to based on the modified information subscription authority, and generate authority modification information at the same time; and push the new target device information and authority modification information to the user terminal.

[0113] Based on the above embodiment, the following further aspects are included:

[0114] The monitoring module 206 is used to monitor the running status, information subscription status and performance parameters of the message server 202.

The performance parameters include various parameters related to the performance of the current message server 202. The monitoring module 206 monitors the message server 202 in real time and promptly issues an alarm and notifies the administrator when an anomaly occurs in the message server 202. In one embodiment, the monitoring module can be selected from the EMQX console.

[0116] Based on the above embodiment, the following further aspects are included:

[0117] The terminal service module 207 is used to respond to the login request of the user terminal 204, connect with the user terminal 204 and send a first token to the user terminal 204; and to receive the second token sent by the user terminal 204, and when the first token matches the second token, send a target token to the user terminal 204.

[0118] The user terminal 204 is also used to initiate a login request to the terminal service module 207, and after the terminal service module 207 is connected, it is used to receive the first token sent by the terminal service module 207 and feedback the first token to the terminal service module 207, and is used to receive the target token sent by the terminal service module 207 and send a connection request to the message server 202, where the connection request carries the target token.

[0119] The message server 202 is also used to connect with the user terminal 204 after authenticating the target token.

[0120] In this embodiment, Figure 6As shown, the information push system also includes a terminal service module 207. When the user terminal 204 needs to connect to the message server 202, the user terminal 204 needs to obtain a target token from the terminal service module 207 to prove the legitimacy of its identity. Specifically, the user terminal 204 first needs to initiate a login request to the terminal service module 207. The login request is used to request to log in to the terminal service module 207. After receiving the login request, the terminal service module 207 connects with the user terminal 204 and sends a first token to the user terminal 204. After receiving the first token, the user terminal 204 resends the first token to the terminal service module 207. The terminal service module 207 then receives the second token sent by the user terminal 204 and compares the first token with the second token. When the first token matches the second token, the identity authentication of the user terminal 204 is passed, and the terminal service module 207 then sends the target token to the user terminal 204. For example, the target token can be a JWTTOKEN.

[0121] After obtaining the target token, the user terminal carries the target token in the connection request and sends the target token to the message server. The message server receives the connection request and parses the target token in the connection request. It then authenticates the target token. If the authentication is successful, it connects to the user terminal. If the authentication fails, it does not connect to the user terminal. The terminal service module of the embodiment of the present invention can verify the identity of the user terminal by sending a first token to the user terminal, receiving a second token fed back by the user terminal, and matching the first token with the second token, thereby preventing untrusted user terminals from connecting to the message server and further improving the security of information.
