Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application 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.
Example 1
Fig. 1 is a flowchart of steps of a data transmission method, which is applied to a gateway device in an internet of things system, where the internet of things system further includes: a first device, a second device, the method comprising:
step 101, receiving a network task sent by a first device.
In the embodiment of the application, the internet of things system is a device interaction system established based on the internet of things, and the internet of things is an information carrier based on the internet, a traditional telecommunication network and the like, so that all common physical objects which can be independently addressed form an interconnection network. The gateway device may be a gateway based on wireless or limited communication technology for relaying data uploaded and issued by the devices. The first device is an electronic device for generating and issuing tasks, and may be an electronic device such as a server or a computer, and the second device is an electronic device such as a server or a computer for receiving and executing network tasks. A network task refers to a task that a first device uses to instruct a second device to perform a specific operation.
The gateway device in the embodiment of the present application may implement the steps of the data transmission method provided in the present application by internally setting a functional module that may perform data transmission through HTTP or other data transmission protocols, and certainly, for a relatively huge internet of things system, a cloud server or a server with a certain storage space may also be used to operate the functional module. Typically, the first device will send the network task to the gateway device after generating the network task, and then the gateway device issues the network task to the second device designated by the network task, so that the gateway device may receive the network task sent by the first device.
Step 102, storing the network task and generating management information of the network task.
In this embodiment of the present application, the management information is related parameters used for managing the issuing and storing of the network task, for example, the effective time period, the source address, the target address, and the like of the network task, which may be specifically determined according to actual requirements, and is not limited herein.
When receiving the network task sent by the first device, the gateway device may store the task data in the network task as a binary file, and generate and store management information of the network task in a folder storing the binary file. In this way, even if the gateway device is connected with a plurality of second devices, the network tasks sent by different second devices can be stored and managed in a differentiated manner.
Step 103, receiving a heartbeat message sent by the second device.
In the embodiment of the application, the heartbeat message is used for monitoring the running state of the machine network memory. Typically the second device will send heartbeat messages to the gateway device at specific time periods to inform the gateway device that the second device is running.
And 104, when the heartbeat message is confirmed to be matched with the management information of the network task, the network task is sent to the second device.
In this embodiment of the present application, after receiving a heartbeat packet sent by a second device, a gateway device performs a query in management information of a stored network task, and matches the gateway task corresponding to the heartbeat packet, that is, queries a network task that is sent by a first device to the second device, and if the network task is currently valid, the gateway device will automatically issue the network task to the second device, and does not need to send a request to the first device to query the network task that needs to be issued to the second device.
For example, referring to fig. 2, the embodiment of the present application is applicable to an application scenario in which a wireless terminal device is connected to a server through a gateway device, where the server 3 sends a generated network task to the gateway device 2 for storage, and when the gateway device 2 receives a heartbeat message sent by the wireless terminal device 1, the gateway device sends the network task to the corresponding wireless terminal device 1.
According to the data transmission method, the storage and management tasks of the network tasks are transferred from the first equipment for generating the tasks to the gateway equipment, so that the network tasks with the management information matched with the heartbeat messages are issued to the second equipment when the heartbeat messages of the second equipment are received, the influence of bandwidth resources between the first equipment and the gateway equipment on network task query is avoided, and the efficiency of the network task query is improved.
Example two
Fig. 3 is a flowchart of steps of another data transmission method provided in the embodiment of the present application, which is applied to a gateway device in an internet of things system, where the internet of things system further includes: a first device, a second device, the method comprising:
step 201, receiving a network task sent by a first device.
This step is described in detail with reference to step 101, and will not be described here.
Step 202, storing the network task and generating management information of the network task.
This step may be described in detail with reference to step 102, and will not be described here again.
Optionally, the management information of the network task further includes: task status.
And step 203, deleting the network task and the management information when the current time is later than the task ending time, or the time difference between the current time and the latest heartbeat message receiving time is greater than a time threshold, or the task state is the ending state, wherein the latest heartbeat message receiving time is the last heartbeat message receiving time of the second device.
In this embodiment of the present application, the current time is a time point when the heartbeat packet is received, the task end time is the latest valid time of the network task, and the task start time is the earliest valid time of the network task. The task state is state information reflecting the execution phase of the network task, for example: setup, prepare, execute, end, suspend, etc. The duration threshold is the longest receiving interval between two heartbeat messages allowed by the second device in the process of being normally connected with the gateway device, and exceeding the duration threshold can be regarded as that the second device has disconnected the network connection of the gateway device.
In the process of storing the network task, the gateway equipment can query the stored management information of the network task at regular time, can query whether the current time is compared with the task ending time of the network task at first, if the current time exceeds the task ending time, can determine that the network task has failed, and delete the network task and the management information; if the current time does not exceed the task ending time, the task state of the network task can be further inquired; if the task state is the ending state, determining that the network task has failed, and deleting the network task and the management information; if the task state is not the ending state, inquiring the time difference between the latest heartbeat message receiving time and the current time of the network task; if the time difference is greater than the time length threshold, determining that the second device has disconnected the network connection with the gateway device, and deleting the network task and the management information; if the time difference is smaller than or equal to the time length threshold value, the network task is determined to be effective, and the network task and the management information are kept continuously.
The above-mentioned judgment logic is only illustrative, and the judging sequence of the task ending time, the task state and the latest heartbeat message receiving time can be arbitrarily replaced, so long as whether the network task is effective or not can be judged according to the task ending time, the task state and the latest heartbeat message receiving time, and the judgment logic is not limited herein.
Step 204, receiving a heartbeat message sent by the second device.
This step is described in detail with reference to step 103, and will not be described here.
Optionally, the management information of the network task includes at least: designating equipment identification, task starting time and task ending time, wherein the heartbeat message at least comprises: and (5) identifying the target equipment.
And step 205, when the target device identifier is the same as the designated device identifier, the current time is later than the task start time, and the current time is earlier than the task end time, confirming that the heartbeat message is matched with the management information of the network task, and sending the network task to the second device.
In this embodiment of the present application, the designated device identifier is a unique identification identifier for indicating the second device, which may be a terminal number, a device number, a network number, or the like, and may specifically be determined according to actual requirements, which is not limited herein. The target device identifier is similar to the designated device identifier, except that the target device identifier is carried by a heartbeat message sent by the second device. Thus, based on this embodiment, the packets of the network task may be configured in the manner of table 1 below:
| preamble code | Data object ID | Data Source ID | Data | Check bit |
| N byte | A byte | A byte | N byte | 2byte |
The preamble is a delimiter for marking the end of timing information, the data target ID is a designated device identifier, the data source ID is a device identifier of the first device, the data is task data, and the check bit is a code for verifying whether a data packet of a network task is legal or not.
Of course, the manner in which the packets of the network task described above are structured indicates an exemplary illustration, so long as the fields in the packets can identify the identity of the second device.
After receiving the heartbeat message sent by the second device, the gateway device may extract the target device identifier of the second device from the heartbeat message, and may determine whether there is a network task that needs to be issued to the second device through the following logic:
comparing the current time with the task ending time; if the current time exceeds the task ending time, confirming that the network task does not exist; if the current time does not exceed the task ending time, comparing the target equipment identifier with the appointed equipment identifier; if the target equipment identifier is different from the designated equipment identifier, confirming that the network task does not exist; if the target equipment identifier is the same as the designated equipment identifier, comparing the current time with the task starting time; if the current time does not exceed the task starting time, confirming that the network task does not exist; and if the current time exceeds the task starting time, confirming that the network task exists, and issuing the network task to the second equipment.
The above-mentioned judgment logic is only illustrative, and the judging sequence of the task ending time, the task starting time and the designated device identifier can be arbitrarily replaced, so long as the judgment of whether the task to be issued to the second device network exists according to the task ending time, the task starting time and the designated device identifier can be performed, and the judgment is not limited herein.
Of course, the management information may also include a task sequence number, a data sequence number, and the like, which may be specifically determined according to actual requirements, and is not limited herein.
And 206, when the sending record corresponding to the network task does not exist, generating the sending record of the sending task corresponding to the network task.
In the embodiment of the application, after each time the network task is sent to the second device, a corresponding sending record may be generated for the second device.
Step 207, when the transmission record corresponding to the network task exists, updating the transmission record according to the current transmission task corresponding to the network task.
In the embodiment of the present application, if there is a transmission record that is transmitting a network task to the second device or a transmission record that last transmits a network task to the second device, the existing transmission record may be overlaid, so as to update the transmission record.
Step 208, transmitting the transmission record to the first device, so that the first device stores the transmission record.
