Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a method and a system for controlling terminal equipment, which are used for solving the technical problem of network resource waste in the prior art.
In the prior art, there are several methods for controlling a terminal device:
1) short-distance point-to-point control based on Bluetooth;
2) controlling based on wifi of a local area network; for example: air conditioners, washing machines, refrigerators, televisions, etc.;
the prior art has the defects that:
terminal control based on bluetooth or wifi has the condition restriction of distance and environment, and more realize the point-to-point control function between the special equipment, and scalability is weak, can not reach platform nature access and management.
Therefore, in the technical field of internet of things, in order to realize remote multi-terminal device control, in the prior art, a cloud control terminal is used, but generally a relay device is required to relay and distribute a cloud instruction.
Specifically, in the prior art, the interaction mode between the transfer device and the terminal device is as follows: the transfer device receives a control instruction sent by the cloud to the terminal device, and the terminal device sends an instruction request to the transfer device to inquire whether the transfer device has the control instruction of the terminal device or not. However, when most of the terminal devices send requests, the terminal devices frequently send instruction requests to the relay device because the relay device does not have a control instruction of the terminal device, and the relay device frequently receives invalid instruction requests until the control instruction is obtained, so that the network resources are excessively occupied, and the network resources are wasted.
It can be seen from the analysis that the existing defects in the prior art are that the existing terminal devices all send request commands to the relay device through the short connection, and the network mechanism of the short connection determines that only the terminal devices can send command requests to the relay device to obtain the control commands.
In view of the defects of the prior art, the present application provides a method for controlling a terminal device through a relay device, and the following describes a technical solution of the present invention in detail with a plurality of embodiments.
Example one
According to the method for controlling the terminal equipment, a control instruction set is prestored in a cache of the transfer equipment; referring to fig. 1, the method specifically includes the following steps:
s101, generating a notification based on a target control instruction aiming at the terminal equipment in the control instruction set;
s102, sending the notification to the terminal equipment through a long connection channel, so that the terminal equipment sends an instruction request for requesting the target control instruction to the transfer equipment through a short connection channel after receiving the notification;
s103, after the instruction request is received, the target control instruction is sent to the terminal equipment through the short connection channel, so that the terminal equipment executes the operation matched with the target control instruction.
It should be noted that the control instruction set pre-stored in the cache of the transit device may be a set formed by control instructions for the terminal device, which are generated by cloud editing, and may include one control instruction or multiple control instructions. After caching, the transit device can generate a corresponding notification.
The transfer device interacting with the terminal in this embodiment may also be a cloud device or a cloud server, but at this time, the cloud device or the cloud server does not have a function of generating a control instruction, and can only receive the control instruction sent by the third party, perform caching, or distribute the control instruction to the terminal device. Therefore, in this embodiment, the device is defined as a relay device, but the device is not limited thereto.
The steps of the method of this embodiment are explained in detail below with reference to fig. 1.
First, S101 is executed to generate a notification based on a target control instruction for the terminal device in the control instruction set.
First, the notification is used to notify the terminal device that a target control command for the terminal device is in the relay device, and therefore, the notification must be generated based on the target control command for the terminal device in the control command set, and is purposefully sent to the corresponding terminal device.
Secondly, the notification can be based on the same control command, a notification is generated and sent to all the terminal devices; alternatively, a plurality of notifications may be generated based on different control commands and sent to different terminal devices.
Then, S102 is executed, and the notification is sent to the terminal device through the long connection channel, so that the terminal device sends an instruction request for requesting the target control instruction to the relay device through the short connection channel after receiving the notification.
It should be noted that, in the communication field, when the network communication uses the TCP protocol, before the actual read/write operation, a connection, i.e. a long connection and a short connection, must be established between the server and the client based on the protocol.
A long connection is a connection in which a plurality of packets can be transmitted continuously over one TCP connection, and if no packets are transmitted during the time that the TCP connection is maintained, both of them need to transmit a detection packet to maintain the connection. The connection mechanism is as follows: connection → data transfer → hold connection (heartbeat) → … … → close connection. This requires that long connections send data packets (heartbeats) at regular intervals when there is no data communication to maintain the connection; in the case of a long connection, the TCP connection between the client and the server for the HTTP data is not closed, and if the client accesses the web page on the server again, the already established connection is used again.
The short connection means that when two communication parties have data interaction, a TCP connection is established, and after the data transmission is completed, the TCP connection is disconnected (the management is simpler, the existing connections are all useful connections, and no additional control means is needed); the connection mechanism is as follows: connection → data transfer → close connection.
In the prior art, the command request defaults to the use of a short connection channel.
Since the long connection path has the connection holding function, it is not necessary to establish a connection path every time a notification is sent, and when there are a plurality of notifications, a plurality of notifications can be quickly sent to the terminal device and can be timely notified to the terminal device. After receiving the notification, the terminal device sends an instruction request for requesting the target control instruction to the transfer device through the short connection channel so as to acquire the target control instruction as early as possible, thereby improving the timeliness of terminal device management and avoiding the waste of cache space resources caused by overlong control instruction cache time.
Next, S103 is executed, and after receiving the instruction request, the target control instruction is sent to the terminal device through the short connection channel, so that the terminal device executes an operation matched with the target control instruction.
It should be noted that, unlike the prior art, the terminal device does not directly send the instruction request to the relay device, but sends the instruction request to the relay device in response to the notification sent by the relay device after receiving the notification, thereby avoiding many invalid instruction requests. And because the connection mechanism of the short connection is connection → data transmission → connection closing, that is, the connection is reestablished every time data is sent, the network response is slow, time is consumed, and the frequent and invalid instruction requests consume more network resources.
The notification is sent to the terminal device through the long connection channel, but cannot be sent to the terminal through the short connection of the prior art.
The foregoing has been used to explain the overall technical solutions, principles, and effects of the present invention, and after understanding the above solutions, it should be noted that there may be a plurality of terminal devices in the present invention, and the relay device may send the same control command to a plurality of terminal devices or send different control commands, and the following description is directed to two special cases.
In the first case:
n terminal devices are provided, wherein N is more than or equal to 2; the control instruction set comprises N control instructions which are respectively matched with each terminal device;
according to the method of the invention, firstly, based on the N control instructions, generating corresponding N notifications;
then, the N notifications are respectively sent to the corresponding N terminal devices through the long connection channel, so that the N terminal devices send corresponding N instruction requests to the transfer device through the short connection channel after receiving the notifications;
and finally, after the N instruction requests are received, the N control instructions are respectively sent to the N corresponding terminal devices through the short connection channel according to the characteristic parameters of each terminal device, so that each terminal device executes the operation matched with the received control instruction.
That is, the relay device sends different control instructions to different terminal devices.
In the second case:
the number of the terminal devices is N, N is more than or equal to 2, and the control instruction set comprises 1 control instruction matched with each terminal device;
then, according to the method of the present invention, first, based on the control instruction, the corresponding 1 notification is generated:
then, the notification is sent to each terminal device through the long connection channel, so that each terminal device sends an instruction request to the transfer device through the short connection channel after receiving the notification;
and finally, after the instruction request is received, sending the control instruction matched with the terminal equipment in the control instruction set to each terminal equipment through the short connection channel so that each terminal equipment executes the operation matched with the control instruction.
That is, the relay device transmits the same control instruction to different terminal devices.
In both the first and second cases, after receiving the command request, the control command matched with the terminal device needs to be selected from the control command set, so as to realize accurate control of different terminal devices.
In order to solve the above problem, as an optional implementation manner, the instruction request carries a characteristic parameter of the terminal device;
then, after receiving the instruction request, sending the target control instruction to the terminal device through the short connection channel, specifically including:
after the instruction request is received, determining the target control instruction from the control instruction set according to the characteristic parameters carried in the instruction request;
and sending the target control instruction to the terminal equipment through the short connection channel.
As mentioned above, in order to quickly send the notification to the terminal device, a long connection channel needs to be established, and for this reason, as an alternative implementation, the relay device and the terminal device have a long connection channel protocol therebetween;
before said sending said notification to said terminal device over said long connection channel, said method further comprises:
based on the long connection channel protocol, establishing a long connection channel with the terminal equipment;
as one of the cases, if the long connection path is successfully established, the step of sending the notification to the terminal device through the long connection path is performed.
As another situation, if the long connection path is failed to be established, the long connection path is continuously established with the terminal device according to a preset time interval until the long connection path is established.
It should be noted that a long connection, although having a connection holding function, does not permanently hold a connection, and it has a holding time that can be set in different server software (e.g., Apache).
Meanwhile, under the condition of bad network, the condition that the long connection channel cannot be established exists. Therefore, in order to realize quick transmission of the notification, if the long connection channel is failed to be established, the long connection channel is continuously established with the terminal device according to a preset time interval until the long connection channel is established.
In addition, in order to ensure that the control instruction can be sent to the terminal device when the long connection path cannot be established, as an optional implementation manner, after the long connection path is established with the terminal device based on the long connection path protocol, the method further includes:
and if the long connection channel is failed to be established, receiving the instruction request through the short connection channel.
As an optional implementation manner, after the receiving the instruction request, sending a control instruction matched with the terminal device in the control instruction set to the terminal device through the short connection channel, so that the terminal device performs an operation matched with the control instruction, the method further includes:
and receiving result data and/or state data of the terminal equipment executing the operation through the short connection channel.
The operation result data and/or the operation state data can be sent to the cloud end to be displayed, and data analysis can also be carried out by downloading, so that the analysis of the terminal equipment is facilitated.
As an optional implementation manner, after the receiving result data and/or status data of the terminal device performing the operation, the method further includes:
and storing the result data and/or the state data of the operation in the transfer equipment.
The operation result data and/or the operation state data can be sent to the cloud end to be displayed, and data analysis can also be carried out by downloading, so that the analysis of the terminal equipment is facilitated.
The technical scheme provided in the embodiment of the application at least has the following technical effects or advantages:
the method of the embodiment is used for transfer equipment, wherein a control instruction set is prestored in a cache of the transfer equipment; a long connection channel protocol is arranged between the transfer equipment and the terminal equipment; the method comprises the following steps: generating a notification based on a target control instruction for the terminal device in the control instruction set; sending the notification to the terminal device through the long connection channel, so that the terminal device sends an instruction request for requesting the target control instruction to the transfer device through the short connection channel after receiving the notification; and after receiving the instruction request, sending the target control instruction to the terminal equipment through the short connection channel so that the terminal equipment executes the operation matched with the target control instruction. Because the transfer equipment sends a notice to the terminal equipment through the long connection channel based on the control instruction in the cache to inform the terminal equipment that the control instruction belonging to the terminal equipment is cached in the transfer equipment, the terminal equipment sends an instruction request to the transfer equipment after receiving the notice, and the transfer equipment sends the cached instruction to the terminal equipment through the short connection after receiving the instruction request. Therefore, the instruction request of the terminal equipment can not be frequently received no matter whether the relay equipment has the control instruction belonging to the terminal equipment or not, as in the prior art, so that the invalid instruction request can be prevented from being frequently received, and the network resource can be saved.
