[0001] The present application relates to the technical field of communication, in particular to a data transmission method, device and storage medium. BACKGROUND

[0002] In the existing Internet of Things framework, in order to improve the reliability of the terminal device executing tasks, the terminal device needs to be monitored. When it is found that the terminal device stops serving, other terminal devices in normal operation need to be monitored and determined to obtain the target terminal device, and the control instruction transmission path is modified and the control instruction is sent to the terminal device in normal operation, so that the terminal device executes the control instruction. For example, when it is monitored that the terminal device A executing the control instruction stops serving, the terminal device B in normal operation is monitored, the control instruction transmission path is modified, and the task to be executed is sent to the terminal device B, so that the terminal device B receives and executes the task to be executed. This control instruction transmission method has low reliability and low efficiency, and additional costs are increased.

[0003] Therefore, how to improve the reliability and efficiency of control instruction transmission is a problem to be solved at present. SUMMARY

[0004] The main purpose of the present application is to provide a data transmission method, device and storage medium, which aims to improve the reliability and efficiency of control instruction transmission.

[0005] In a first aspect, the present application provides a data transmission method applied to a central control device, wherein the central control device has established a soft bus channel with a plurality of terminal devices, and the data transmission method comprises the following steps:

[0006] Obtaining a task to be executed;

[0007] According to the preset device routing information and the soft bus channel, the task to be executed is sent to each terminal device in turn, and after sending the task to be executed to each terminal device, a data transmission response feedback by the terminal device is received;

[0008] When the data transmission response feedback by any terminal device is that the task to be executed has been received, it is determined that the task to be executed has been successfully transmitted and the sending of the task to be executed is stopped.

[0009] In a second aspect, the present application further provides a central control device, which comprises a processor, a memory and a computer program stored in the memory and executable by the processor, wherein when the computer program is executed by the processor, the steps of the data transmission method described above are realized.

[0010] Thirdly, this application also provides a computer-readable storage medium storing a computer program, wherein when the computer program is executed by a processor, it implements the steps of the data transmission method described above.

[0011] This application provides a data transmission method, device, and storage medium. The method involves acquiring a task to be executed; sending the task to each terminal device in a polling manner according to preset device routing information and a soft bus channel; and receiving a data transmission response from each terminal device after sending the task. When a data transmission response from any terminal device confirms receipt of the task, the method determines that the task has been successfully transmitted and stops polling. This solution significantly improves the reliability and efficiency of task transmission by polling the terminals and determining successful transmission upon receiving feedback from a terminal device that the task has been received.

[0021] This application provides a data transmission method, device, and storage medium. The data transmission method can be applied to a central control device, which can be an electronic device such as a router, switch, mobile phone, tablet computer, laptop computer, or desktop computer. For example, the central control device is a router. The router has established a soft bus channel with multiple terminal devices. The router obtains tasks to be executed; it sends the tasks to be executed to each terminal device in a polling manner according to preset device routing information and the soft bus channel; and after sending the tasks to each terminal device, it receives a data transmission response from that terminal device. When it receives a data transmission response from any terminal device indicating that the tasks to be executed have been received, it determines that the tasks to be executed have been successfully transmitted and stops polling to send more tasks.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a data transmission method provided in an embodiment of this application.

[0024] like Figure 1 As shown, the data transmission method includes steps S101 to S103.

[0025] Step S101: Obtain the task to be executed.

[0026] The central control device and the plurality of terminal devices establish a soft bus channel, the terminal devices can be selected according to actual conditions, and embodiments of the present application do not make specific limitations thereon, for example, the terminal devices can be mobile phones, computers, switches, desktop computers, notebook computers and the like, and it should be noted that the plurality of terminal devices are hot standby devices, the plurality of terminal devices can execute the to-be-executed task, and the plurality of terminal devices can be the same plurality of devices or a plurality of different devices, for example, the plurality of terminal devices include four mobile phones, and for another example, the plurality of terminal devices include one mobile phone, two desktop computers and two notebook computers.

[0027] It should be noted that the to-be-executed task is a task that can be executed by each terminal device, and the to-be-executed task can be set according to actual conditions, and embodiments of the present application do not make specific limitations thereon, for example, the to-be-executed task can be a device A start instruction.

[0028] In an embodiment, the to-be-executed task sent by an upstream device is acquired. The upstream device is a device that sends the to-be-executed task, and the device can be selected according to actual conditions, and embodiments of the present application do not make specific limitations thereon, for example, the upstream device can be a server (a cloud server, a rack server, a blade server, a tower server and a cabinet server and the like), a gateway device (a base station and a router and the like) and a terminal device (a mobile phone, a notebook computer, a desktop computer and a tablet computer and the like). The to-be-executed task can be accurately acquired by receiving information transmitted by the upstream device.

[0029] In an embodiment, an authentication request for establishing a soft bus channel is sent to each terminal device, so that each terminal device receives the authentication request and performs identity authentication according to the authentication request, and a terminal device that feeds back that the identity authentication is passed establishes a soft bus channel with the central control device. The identity authentication of each terminal device can improve the security of task transmission.

[0030] In an embodiment, the central control device listens to the terminal device, and after listening to the terminal device, sends an authentication request to the terminal device. After the terminal device receives the authentication request, it is determined whether the authentication request is located in a preset identity library. When the identity information is located in the preset identity library, the central control device is fed back that the identity authentication is passed, and when the identity information is not located in the preset identity library, the central control device is fed back that the identity authentication is not passed. The identity information can be set according to actual conditions, and embodiments of the present application do not make specific limitations thereon, for example, the identity information can be a device ID and account information and the like. According to whether the identity information is located in the preset identity library, it can be accurately known whether the identity authentication is passed, greatly improving the efficiency and accuracy of the establishment of the soft bus channel.

[0031] For example, the authentication request is sent to the terminal device 1, the terminal device 2, the terminal device 3, the terminal device 4 and the terminal device 5, and the identity authentication pass information fed back by the terminal device 1, the terminal device 3 and the terminal device 5 is received, and the soft bus channel is established with the terminal device 1, the terminal device 3 and the terminal device 5.

[0032] In an embodiment, the authentication request for establishing the soft bus channel sent by each terminal device is acquired, identity authentication is performed on the authentication request sent by each terminal device, and the soft bus channel is established with the terminal device corresponding to the identity authentication pass of the authentication request. By performing identity authentication on each terminal device, the security of task transmission can be improved.

[0033] In an embodiment, the identity authentication on the authentication request sent by each terminal device can be performed in the following manner: whether the identity information of the terminal device is located in a preset identity library is determined, if the identity information of the terminal device is located in the preset identity library, it is determined that the identity authentication of the terminal device is passed, and the soft bus channel is established with the terminal device. The identity information can be set according to actual conditions, which is not limited in the embodiment of the present application. For example, the identity information can be a device ID and account information. According to whether the identity information is located in the preset identity library, it can be accurately known whether the identity authentication is passed, and the efficiency and accuracy of the establishment of the soft bus channel are greatly improved.

[0034] For example, the identity information A sent by the terminal device 1, the identity information B sent by the terminal device 2, the identity information C sent by the terminal device 3, the identity information D sent by the terminal device 4 and the identity information E sent by the terminal device 5 are received, and the identity information B of the terminal device 2, the identity information D of the terminal device 4 and the identity information E of the terminal device 5 are located in the preset identity library, and the soft bus channel is established with the terminal device 2, the terminal device 4 and the terminal device 5.

[0035] In an embodiment, the message routing information interface and the sending byte extension interface are set, the message routing information interface is used for data interaction with the device sending the to-be-executed task, and the sending byte extension interface is used for data interaction with each terminal device through the soft bus channel. The selection of the message routing information interface and the sending byte extension interface can be set according to actual conditions, which is not limited in the embodiment of the present application. For example, the message routing information interface can be a setMessageRouteinfo interface, and the sending byte extension interface can be a SendBytesExt interface.

[0036] For example, as shown in FIG. 6, the message routing information interface and the sending byte extension interface are set, the message routing information interface is used for data interaction with the device sending the to-be-executed task, and the sending byte extension interface is used for data interaction with each terminal device through the soft bus channel. Figure 2As shown, the server 10 establishes a communication connection with the central control device 20, and the central control device 20 sends an authentication request for establishing a soft bus channel to the terminal device A 31, the terminal device B 32 and the terminal device C 33 in turn, and each of the terminal device A 31, the terminal device B 32 and the terminal device C 33 receives the authentication request and authenticates the authentication request, generates an identity authentication pass response when the authentication request is passed, and sends the identity authentication pass response to the central control device 20, and the central control device 20 receives the identity authentication pass responses sent by each of the terminal devices, and establishes a soft bus channel with the terminal device A 31, the terminal device B 32 and the terminal device C 33 respectively, and obtains a soft bus channel diagram as shown. Figure 2

[0037] In step S102, the preset device routing information and the soft bus channel are used to pollingly send the to-be-executed task to each of the terminal devices, and a data transmission response fed back by each terminal device is received after the to-be-executed task is sent to the terminal device.

[0038] In an embodiment, as shown in Figure 3 Step S102 includes sub-step S1021 to sub-step S1022.

[0039] In an embodiment, the preset device routing information sent by an upstream device is acquired, and the preset device routing information is stored. The storage of the preset device routing information can improve the efficiency and accuracy of the forwarding of the to-be-executed task.

[0040] In sub-step S1021, the to-be-executed task is parsed to generate a target to-be-executed task.

[0041] After the to-be-executed task is acquired, the to-be-executed task is parsed to generate a target to-be-executed task, and the target to-be-executed task can be directly executed by the terminal device. It should be noted that the manner of parsing the to-be-executed task can be selected according to actual conditions, and the embodiment of the present application does not make a specific limitation thereon. For example, the data packet of the to-be-executed task is parsed to generate the target to-be-executed task. The to-be-executed task is parsed to accurately generate the target to-be-executed task.

[0042] In sub-step S1022, the preset device routing information and the soft bus channel are used to pollingly send the target to-be-executed task to each of the terminal devices.

[0043] The preset device routing information includes a random polling transmission routing strategy, a designated transmission routing strategy and a historical transmission routing strategy, etc.

[0044] ​In an embodiment, when the preset device routing information comprises a random polling transmission routing strategy, the target task to be executed is sent to each terminal device according to the random polling transmission routing strategy through the soft bus channel, and a data transmission response fed back by the terminal device is received after the task to be executed is sent to each terminal device. According to the random polling transmission routing strategy, the target task to be executed is sent to each terminal device, which greatly improves the efficiency of sending the target task to be executed.

[0045] For example, the terminal devices which have established the soft bus channel with the central control device comprise terminal device A, terminal device B, terminal device C and terminal device D. The task to be executed is sent to the terminal device C according to the random polling transmission routing strategy, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the task to be executed is sent to the terminal device A, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the task to be executed is sent to the terminal device B. When the data transmission response fed back by the terminal device B based on the task to be executed is received, and the data transmission response is that the task to be executed is not received, the task to be executed is sent to the terminal device D. When the data transmission response fed back by the terminal device D based on the task to be executed is received, and the data transmission response is that the task to be executed is not received, it is determined that the transmission of the task to be executed fails.

[0046] For example, the terminal devices which have established the soft bus channel with the central control device comprise terminal device A, terminal device B, terminal device C and terminal device D. The task to be executed is sent to the terminal device C according to the random polling transmission routing strategy, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the task to be executed is sent to the terminal device A, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is received, it is determined that the transmission of the task to be executed succeeds and the task to be executed is stopped from being sent.

[0047] In an embodiment, when the device routing information comprises a specified transmission routing strategy, the target task to be executed is sent to each terminal device according to the specified transmission routing strategy through the soft bus channel, and a data transmission response fed back by the terminal device is received after the task to be executed is sent to each terminal device. The specified transmission routing strategy can be a priority routing strategy. According to the specified transmission routing strategy, the target task to be executed is sent to each terminal device, which greatly improves the efficiency of sending the target task to be executed.

[0048] The terminal devices which have established the soft bus channel with the central control device include terminal device A, terminal device B, terminal device C and terminal device D. The transmission routing strategy is a priority routing strategy. The order of the priority levels in the priority routing strategy is terminal device C, terminal device B, terminal device A and terminal device D. The terminal device C is sent a task to be executed, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device B is sent the task to be executed, and a data transmission response fed back by the terminal device B based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device A is sent the task to be executed, and a data transmission response fed back by the terminal device A based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device D is sent the task to be executed, and a data transmission response fed back by the terminal device D based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, it is determined that the transmission of the task to be executed fails.

[0049] The terminal devices which have established the soft bus channel with the central control device include terminal device A, terminal device B, terminal device C and terminal device D. The transmission routing strategy is a priority routing strategy. The order of the priority levels in the priority routing strategy is terminal device C, terminal device B, terminal device A and terminal device D. The terminal device C is sent a task to be executed, and a data transmission response fed back by the terminal device C based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device B is sent the task to be executed, and a data transmission response fed back by the terminal device B based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device A is sent the task to be executed, and a data transmission response fed back by the terminal device A based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, the terminal device D is sent the task to be executed, and a data transmission response fed back by the terminal device D based on the task to be executed is received. When the data transmission response is that the task to be executed is not received, it is determined that the transmission of the task to be executed fails.

[0050] In an embodiment, when the device routing information is a historical transmission routing strategy, at least one target terminal device of historical transmission is acquired according to the historical transmission routing strategy; and the target task to be executed is sent to each terminal device through the soft bus channel in a polling manner. The target task to be executed is sent to each terminal device in a polling manner according to the historical transmission routing strategy, which greatly improves the efficiency of sending the target task to be executed.

[0051] According to the historical transmission routing strategy, at least one target terminal device of historical transmission is acquired, the target terminal device includes terminal device A, terminal device B, terminal device C and terminal device D, the to-be-executed task is sent to the terminal device C, and the data transmission response fed back by the terminal device C based on the to-be-executed task is received; when the data transmission response is that the to-be-executed task is not received, the to-be-executed task is sent to the terminal device A, and the data transmission response fed back by the terminal device C based on the to-be-executed task is received; when the data transmission response is that the to-be-executed task is not received, the to-be-executed task is sent to the terminal device B; and when the data transmission response fed back by the terminal device B based on the to-be-executed task is received, the to-be-executed task is sent to the terminal device D when the data transmission response is that the to-be-executed task is not received, and the data transmission response fed back by the terminal device D based on the to-be-executed task is received; when the data transmission response is that the to-be-executed task is not received, it is determined that the to-be-executed task transmission fails.

[0052] In step S103, when the data transmission response fed back by any terminal device is that the to-be-executed task is received, it is determined that the to-be-executed task has been transmitted successfully, and the polling transmission of the to-be-executed task is stopped.

[0053] In an embodiment, when the data transmission response fed back by any terminal device is that the to-be-executed task is received, it is determined that the to-be-executed task has been transmitted successfully, and the polling transmission of the to-be-executed task is stopped.

[0054] As shown in the example, Figure 4 As shown in the example, the server 41 transmits the to-be-executed task to the central control device 42, the central control device 42 acquires the to-be-executed task, sends the to-be-executed task to the terminal device A, the terminal device A 43 feeds back the data transmission response according to whether the to-be-executed task is received, when the central control device 42 receives the data transmission response of the terminal device A 43, the data transmission response is that the transmission fails, the to-be-executed task is sent to the terminal device B 44, the terminal device B 44 feeds back the data transmission response according to whether the to-be-executed task is received, when the central control device 42 receives the data transmission response of the terminal device B 44, the data transmission response is that the transmission succeeds, and it is determined that the to-be-transmitted task transmission succeeds.
