It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Referring to fig. 1, fig. 1 is a schematic flowchart of a multi-terminal joint control method based on a local area network according to an embodiment of the present invention. The method can be operated in terminals such as smart phones (such as Android phones, IOS phones and the like), tablet computers, notebook computers, smart devices and the like. The terminal is shown in fig. 1 by a series, and the steps of the method include steps S101 to S103.
Step S101, if a terminal control instruction initiated by a user is detected, the terminal control instruction is analyzed to determine the identification information of a target controlled terminal and the target control instruction.
In this embodiment, a user can initiate a target control instruction to a target controlled terminal through a control terminal, and the control terminal can control other terminals located in the same local area network as the control terminal after detecting the terminal control instruction initiated by the user. Specifically, a TCP standard communication protocol and a routing end in a local area network are adopted to realize the forwarding of control instructions, establish a connection channel, realize the transmission and the reception of various types of data packets and the like, namely, the joint control among a plurality of terminals in the same local area network is effectively realized. The local area network communication technology is a communication mode with wide application, high efficiency and low power consumption, and is particularly suitable for intercommunication with multiple terminals in a network in a small range.
For example, if the control terminal is a mobile terminal, such as a smart phone, and the controlled terminal is a smart television, the user can realize interconnection control between the mobile terminal and the smart television through a local area network networking communication technology, that is, the operation control mode is more flexible and convenient, the limitation of one-to-one matching between the smart television and an entity remote controller can be solved without an external internet, and the connection control between multiple terminals is directly realized through the local area network.
Generally, a user can initiate a terminal control instruction through a control terminal, where the terminal control instruction includes identification information of a target controlled terminal and a target control instruction, the identification information of the target controlled terminal refers to identification information of the controlled terminal, and generally, the identification information may be a name of the corresponding controlled terminal, or information such as a model; the target control instruction is a command for controlling the corresponding controlled terminal by the user, for example, a control instruction for starting up, changing channels, shutting down or adjusting volume is sent to the smart television in the same local area network through the smart phone.
Step S102, acquiring corresponding IP addresses and effective port information from a preset database according to the determined identification information of the target controlled terminal, wherein the preset database comprises at least one IP address, each IP address is correspondingly associated with corresponding effective port information, and different IP addresses are associated with different identification information.
In this embodiment, the preset database stores the pre-stored IP addresses and valid port information of different controlled terminals. In the local area network, a controlled terminal is usually provided with an IP address, and each controlled terminal is associated with an identification information, so in order to determine the IP address of each controlled terminal, different identification information is usually associated with different IP addresses. Generally, the identification information and the valid port information of the corresponding target controlled terminal can be determined from a preset database through the determined identification information of the target controlled terminal.
In general, the controlled terminal may include a plurality of port information, and when the control instruction needs to be sent, it needs to determine valid port information of a target controlled terminal, so as to implement accurate sending of the control instruction, where the valid port information may be one of the plurality of port information of the controlled terminal, and is not limited in this embodiment.
Step S103, the target control instruction, the acquired IP address of the target controlled terminal and the effective port information are sent to a routing end in a local area network, so that the routing end sends the target control instruction to the corresponding target controlled terminal according to the acquired IP address of the target controlled terminal and the effective port information, and the target controlled terminal is controlled.
In this embodiment, after the control terminal sends the target control instruction, the acquired IP address of the target controlled terminal, and the effective port information to the routing end in the local area network, the router can find the target controlled terminal according to the IP address, and send the target control instruction to the target controlled terminal through the effective port information of the corresponding target controlled terminal, so that the target controlled terminal realizes corresponding functional operation according to the target control instruction, that is, the control terminal controls the target controlled terminal located in the same local area network as the target controlled terminal.
In an embodiment, the method further comprises the steps of:
and step S104, if the controlled feedback information forwarded by the target controlled terminal through the router is not received within a second preset time threshold, displaying a prompt box for the user to select whether to initiate the terminal control instruction again.
In this embodiment, in order to further control the target controlled terminal, after the target controlled terminal executes the target control instruction, a corresponding controlled feedback message may be generated, and the controlled feedback message may be forwarded to the control terminal through the router, so that the user can know the control condition of the control terminal conveniently. If the terminal does not receive the controlled feedback information forwarded by the target controlled terminal through the router within the second preset time threshold, it indicates that a state that the control terminal and the target controlled terminal are not intercommunicated, that is, a signal disconnection state may exist at this time, and at this time, a prompt box may be displayed for the user to select whether to initiate the terminal control instruction again, so as to further initiate control on the target controlled terminal.
In summary, the embodiment of the present invention provides a multi-terminal joint control method based on a local area network. The method of the embodiment of the invention can realize more flexible and convenient interconnection control among different terminals, meet more functional operations and improve the use experience of users.
Referring to fig. 2, fig. 2 is a schematic flowchart of a multi-terminal joint control method based on a local area network according to another embodiment of the present invention. The steps of the method include steps S201a to S203. The related explanations and detailed descriptions of the steps similar to steps S101-S103 in the above embodiment are not repeated herein, and the following detailed descriptions are the added steps in this embodiment.
Step S201a, sending a detection packet to a controlled terminal in the local area network through a routing end in the local area network every a preset time range, so that the controlled terminal generates a response packet, where the response packet includes an IP address and port information of the controlled terminal.
In this embodiment, since only terminals in the same lan can implement communication interconnection and control, in order to ensure that the terminals can implement joint control, the control terminal needs to send a detection packet to a controlled terminal in the lan at intervals of a preset time range. The preset time range may be set according to a requirement of a user, for example, may be any one of 2min, 3min, or 4min, and is not limited in this embodiment. In addition, other terminals than the control terminal, which are located in the local area network where the control terminal is located, may also be used as the controlled terminals. After the controlled terminal receives the detection data packet distributed by the router in the local area network where the controlled terminal is located, a corresponding response data packet can be generated. The response packet may include an IP address of the controlled terminal and port information, where the IP address of the controlled terminal refers to a unique address of the controlled terminal in the local area network, and the IP address is used to determine the location of the controlled terminal, and the port information refers to a related port of the controlled terminal. For example, for 192.168.0.1:8899, the IP address is 192.168.0.1, and the port information is 8899, through which the sending of the command to the controlled terminal can be realized.
Step S201b, it is determined whether a response packet forwarded by the controlled terminal through the routing end is detected within a first preset time threshold.
In this embodiment, in order to determine that the detection packet sent by the control terminal is received by the controlled terminal, it needs to be determined whether a response packet forwarded by the controlled terminal through the routing end is detected within a first preset time threshold. The first preset time threshold may be set according to a requirement of a user, for example, the first preset time threshold may be 2min, may also be 3min, and may also be 4min, which is not limited in this embodiment.
Meanwhile, if the response packet forwarded by the controlled terminal through the routing end is not detected within the first preset time threshold, it indicates that the controlled terminal is not turned on or is not in the local area network, so it may choose to return to the step S201a for reconnection.
Step S201c, if a response packet forwarded by the controlled terminal through the routing end is detected within a first preset time threshold, parsing the response packet to obtain identification information of the controlled terminal and IP address and port information associated with the identification information.
In this embodiment, if the control terminal detects a response packet forwarded by the controlled terminal through the routing terminal within the first preset time threshold, it indicates that the control terminal and the controlled terminal at this time are located in the same local area network, and joint control may be implemented. After receiving the response data packet, the control terminal can parse the response data packet, so as to obtain the identification information of the controlled terminal and the IP address and the port information associated with the identification information, so as to perform subsequent operations.
Step S201d, storing the acquired identification information of the controlled terminal and the IP address and port information associated with the identification information into a preset database, so as to establish joint control with the controlled terminal.
In this embodiment, the number of the controlled terminals may be set according to an actual situation, so that in order to facilitate a user to select a controlled terminal to be controlled, the acquired identification information of the controlled terminal, and the IP address and the port information associated with the identification information may be stored in a preset database, so as to facilitate an effect of implementing an associated control between the control terminal and the controlled terminal.
Step S201, if a terminal control instruction initiated by a user is detected, the terminal control instruction is analyzed to determine the identification information of the target controlled terminal and the target control instruction.
Step S202, acquiring corresponding IP addresses and effective port information from a preset database according to the determined identification information of the target controlled terminal, wherein the preset database comprises at least one IP address, each IP address is correspondingly associated with corresponding effective port information, and different IP addresses are associated with different identification information.
In one embodiment, as shown in fig. 3, the step S202 includes:
step S301, obtaining the corresponding IP address from the preset database according to the determined identification information of the target controlled terminal.
In this embodiment, the control terminal can obtain the IP address associated with the determined target controlled terminal from the preset database according to the determined identification information of the target controlled terminal, where the preset database usually includes the IP address of the controlled terminal, and since the controlled terminal may be multiple, the IP address at this time may also be multiple.
Step S302, obtaining corresponding port information according to the IP address.
In this embodiment, since the IP address is provided with a plurality of corresponding port information, that is, each controlled terminal is provided with a plurality of port information, in order to prevent the joint control between the controlled terminal and the control terminal from being affected, it is usually selected to select and use valid port information from the port information to implement the transmission of data such as instructions. Therefore, the control terminal can obtain the corresponding port information according to the IP address so as to execute the following steps.
Step S303, selecting one of the port information from the port information as valid port information according to a preset random selection rule.
In this embodiment, the control terminal may select one of the port information as the valid port information from the port information according to a preset random selection rule, where the preset random selection rule may be a random selection function rand (), and of course, the specific implementation is not limited in this embodiment.
In an embodiment, step S301 of the method further includes the following steps:
step S301a, it is determined whether the preset database includes the identification information of the determined target controlled terminal.
In this embodiment, since there may be a situation that data is cleared in the preset database of the control terminal, before acquiring the IP address corresponding to the determined target controlled terminal from the preset database according to the determined identification information of the target controlled terminal, it is further required to determine whether the preset database includes the determined identification information of the target controlled terminal. If the preset database does not include the identification information of the determined target controlled terminal, the step S201a is returned, that is, the interconnection between the control terminal and the controlled terminal is reestablished. If the preset database includes the determined identification information of the target controlled terminal, the step S301 is executed.
Step S203, sending the target control instruction, the acquired IP address of the target controlled terminal, and the effective port information to a routing end in a local area network, so that the routing end sends the target control instruction to a corresponding target controlled terminal according to the acquired IP address of the target controlled terminal and the effective port information, and implements control of the target controlled terminal.
It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), or the like.
