Attached drawing, the present invention is described in more detail.
Referring to Fig. 1, for the flow chart of the method for the switching terminal use state provided in one embodiment of the invention.With
In lower step explanation, secondary user terminal refers to student terminal, and primary user end refers to teacher's terminal.Under normal circumstances, primary user end can
PC teacher side and PAD teacher side each one are set, and the quantity at Duplicate user end is not particularly limited.
As an embodiment of the present invention, the method for the switching terminal use state includes:
Step 101, the first user terminal is connected to network MQTT server, and subscribes to MQTT service theme message.
Wherein, MQTT (Message Queuing Telemetry Transport, the message queue telemetering transmission) clothes
Theme message of being engaged in includes the first theme message and second theme message, corresponds respectively to class state and after class state.Therefore, on
The theme message of class and theme message after class are different, respectively the first theme message and second theme message, the present invention
Embodiment uses different theme messages to distinguish class state and after class state.
It should be pointed out that the title of the first theme message and second theme message can be preset, such as first main
The title of topic message can be set as/class/begin, and the title of second theme message can be set as/class/end, with
Different theme messages is chosen convenient for user, to distinguish class state and after class state.
Optionally, the first user terminal is connected to network MQTT server, and subscribes to MQTT service theme message automatically,
Described in network MQTT server include Cloud Server or thin cloud server.Optionally, the first user terminal in step 101
It can be secondary user terminal, such as student terminal, secondary user terminal can have multiple.
As yet another embodiment of the present invention, the step of the first user terminal is connected to network MQTT server, includes:
When the starting of the first user terminal, UDP (User Datagram Protocol, User Datagram Protocol are sent to current local area network
View) broadcast, if receiving the UDP response of thin cloud server within a preset time, the IP address sent by thin cloud server,
The MQTT service being connected on thin cloud server.
Therefore, when the first user terminal starts, udp broadcast is sent to current local area network, if current local area network exists
There is thin cloud server, then when thin cloud server receives the udp broadcast of the first user terminal transmission, response udp broadcast is indicated micro-
The presence of Cloud Server.So the first user terminal obtains the IP address of thin cloud server, is then provided by MQTT program
Contiguous function is connected to the service of the MQTT on thin cloud server.
Further, the method also includes: if the first user terminal is within a preset time (such as 3 seconds or 5 seconds)
The UDP response of thin cloud server is not received, and the judgement of the first user terminal currently has internet, then takes by cloud MQTT
The domain name and port numbers of business are connected to the MQTT service in cloud.In this embodiment, the MQTT service can be deployed to such as
Ali's cloud or Tencent's cloud.
It should be pointed out that will start a thread when starting of the first user terminal, constantly to current local
Net sends udp broadcast, it is therefore an objective to the presence of oneself is broadcasted, if current local area network environment is with the presence of thin cloud server, thin cloud
Server can reply a udp broadcast when receiving the udp broadcast of the first user terminal, indicate the presence of thin cloud server.So
First user terminal can obtain the IP address of thin cloud server, to be connected to by the contiguous function that MQTT program provides micro-
MQTT service above Cloud Server.
Therefore, when the first user terminal is in internet environment, the theme message that the first user terminal issues will be sent out
The MQTT to Cloud Server is sent to service.When the first user terminal is in LAN environment, what the first user terminal issued
Theme message services the MQTT being sent on thin cloud server.
It should be pointed out that thin cloud server is with Cloud Server, there are following differences:
The placement location of the two is different, and Cloud Server can be generally arranged in the computer room of operating side；And thin cloud server meeting
It is arranged in field of employment, such as classroom；
Thin cloud server and Cloud Server all can provide network data resource service, Cloud Server be to provide total data and
Resource, and thin cloud server is the subset of Cloud Server resource；
Cloud Server is the server in internet, and thin cloud server is the server in local area network；
Cloud Server be it is shared, all line personnels can be used, and thin cloud server be comparatively it is dedicated, limit
It just can be used in the crowd of particular range, for example be placed in the indoor thin cloud server of religion, be then only limited to indoor in the religion
Personnel (Faculty and Students) use, and the personnel outside classroom are not available then.
Optionally, thin cloud server is mounted in a classroom, other classrooms are not available the thin cloud server.Every religion
Room is installed by one thin cloud server.
Step 102, the selection of second user terminal currently needs state to be used, and the corresponding MQTT service of the state is led
Topic message is sent to network MQTT server.
It should be pointed out that the MQTT service theme that the corresponding MQTT service theme message of the state and step 101 are subscribed to
Message is the same, such as corresponding first theme message of class state or the corresponding second theme message of state after class.?
In the step, according to actual needs, selection currently needs state to be used to second user terminal, and by the corresponding MQTT of the state
Service theme message is sent to the MQTT server on network server.Optionally, the second user terminal in step 102 can be with
It is primary user's terminal, such as teacher's terminal.
As another embodiment of the invention, before step 102, the method also includes: second user terminal connects
It is connected to network MQTT server.I.e. when second user terminal starts, udp broadcast is sent to current local area network, if default
The UDP response of thin cloud server is received in time, then the IP address sent by thin cloud server is connected on thin cloud server
MQTT service.
Specifically, when second user terminal starts, udp broadcast is sent to current local area network, if current local area network is deposited
There is thin cloud server, then when thin cloud server receives the udp broadcast of second user terminal transmission, response udp broadcast is indicated
The presence of thin cloud server.So second user terminal obtains the IP address of thin cloud server, is then provided by MQTT program
Contiguous function be connected to the MQTT on thin cloud server service.
Further, the method also includes: if second user terminal is within a preset time (such as 3 seconds or 5 seconds)
The UDP response of thin cloud server is not received, and the judgement of second user terminal currently has internet, then takes by cloud MQTT
The domain name and port numbers of business are connected to the MQTT service in cloud.In this embodiment, the MQTT service can be deployed to such as
Ali's cloud or Tencent's cloud.
It should be pointed out that will start a thread when starting of second user terminal, constantly to current local
Net sends udp broadcast, it is therefore an objective to the presence of oneself is broadcasted, if current local area network environment is with the presence of thin cloud server, thin cloud
Server can reply a udp broadcast when receiving the udp broadcast of second user terminal, indicate the presence of thin cloud server.So
Second user terminal can obtain the IP address of thin cloud server, to be connected to by the contiguous function that MQTT program provides micro-
MQTT service above Cloud Server.
Therefore, when second user terminal is in internet environment, the theme message that second user terminal issues will be sent out
The MQTT to Cloud Server is sent to service.When second user terminal is in LAN environment, what second user terminal issued
Theme message services the MQTT being sent on thin cloud server.
As yet another embodiment of the present invention, thin cloud server can be added in classroom to provide local area network clothes
Business.In LAN environment, the first user terminal, second user terminal all operation and response pass through thin cloud server
It is completed in local area network, when major and minor user terminal needs to be attached to internet, transfer can also be carried out by thin cloud server.
After adding thin cloud server, the first user terminal, second user terminal need the MQTT by receiving the transmission of thin cloud server
Client service response udp broadcast obtains the IP address of thin cloud server, the MQTT service being connected on thin cloud server.
Step 103, network MQTT server disappear the MQTT service theme that the second user terminal received issues
Breath is sent to the first user terminal, and first user terminal uses shape according to the MQTT service theme message switching received
State.
When use state be upper class hour, can set limited for the function of the application program of the first user terminal, such as
Do not allow to download, the application program that installation and opening are unrelated with classroom.It is possible to further be arranged to not allowing open application
The icon of program locks, and when use state is switched to lower class hour, cancels these limitations automatically.
It, can also be by the way that MQTT message white list be arranged, so that the first user is whole as yet another embodiment of the present invention
It can be with dynamic opening, closing application program when holding state at school.Such as first user terminal be mounted with that a default is attended class shape
Open application program is not allowed when state, when the state of the first user terminal is class state, default icon is locked, and first uses
Family terminal is not available the application program.But the first user terminal can be set as opening from the background, and apply journey this is opened
The instruction of sequence is sent to network MQTT server, and such first user terminal allows to open the message of the application program receiving
Afterwards, icon, which reforms into, does not lock, and the application program then can be used in the first user terminal.
Specifically, it pre-defines one and applies white list theme, for example be "/hitecloud/iclass/applist ",
First user terminal can subscribe to this theme message.It can be arranged in second user terminal using white list, second user
This then can be pushed to network MQTT server using white list theme and using white list by terminal.And network MQTT is serviced
This message can be pushed to the first user terminal having subscribed using white list theme message by device automatically.First user terminal receives
After PUSH message, parses the application packet name in message and corresponding application program is unlocked.
In order to control the use state of the first user terminal, the first user terminal can be set, and to be unable to manual switching upper and lower
Class mode, only second user terminal can carry out state switching.
It can be seen that the method for switching terminal use state provided in an embodiment of the present invention passes through different theme message areas
Point class state and after class state, guarantee student of upper class hour can only do and attend class related thing, and Auto-Sensing is gone to school and left school
State simultaneously automatically switches class state and after class state, easy to use, efficiently, greatly improves user experience.User only needs
