It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a data transmission method according to an embodiment of the present invention, which is applicable to a case where a non-networked device automatically transmits data. The method may be performed by a data transfer device, which may be implemented in hardware and/or software, integrated in a controller in the edge gateway. Wherein the edge gateway comprises a built-in memory with dual interfaces. The edge gateway can be connected with the external device through a first interface of the internal memory.
As shown in fig. 1, the method may include the steps of:
and S110, responding to a data storage instruction sent by the server, supplying power to the first interface so that the external device stores the device data into the internal memory through the first interface in the power-on state.
The data storage instruction may refer to that the edge gateway receives a request sent by the server to store the device data in the external device in an internal memory in the edge gateway. The first interface may be an interface, e.g. a USB interface, that is externally present on the edge gateway surface. An external device may refer to a non-networked device disposed outside of the edge gateway. Wherein, the external device can automatically inquire the connected internal memory. An edge gateway may refer to a gateway deployed at the edge side of a network. The built-in memory may refer to a memory integrated in the edge gateway having a dual USB function. For example, the first interface of the internal memory is connected to the external device through a USB data line.
Specifically, the edge gateway may supply power to the first interface when receiving a data storage instruction sent by the server, and at this time, the external device connected to the first interface of the internal memory becomes a controller of the internal memory, so that the external device may automatically store the generated device data in the internal memory through the first interface in the power-on state.
And S120, if the preset data sending condition is met currently, powering off the first interface, supplying power to the second interface of the built-in memory, and sending the equipment data stored in the built-in memory to the server through the second interface in the power-on state.
Wherein the second interface may be an internal interface built into the edge gateway. The second interface may be connected to a module in the edge gateway that sends data over the network. The preset data transmission condition may be a trigger condition for transmitting data, which is set in advance. For example, the preset data transmission condition may refer to that the storage of the generated device data is completed each time, or a data acquisition instruction transmitted by the server is received or the current time reaches the timing.
Specifically, in the process of storing the device data into the internal memory, the edge gateway detects whether the current state of the internal memory meets a preset data sending condition. If the current state of the built-in memory does not meet the preset data sending condition, the first interface is kept in the power-on state, and at the moment, the external device is still a controller of the built-in memory in the edge gateway until the current state of the built-in memory meets the preset data sending condition. If the current state of the internal memory meets the preset data sending condition, the first interface is powered off, and the second interface of the internal memory is powered on, so that a controller of the internal memory is switched from the external device to the edge gateway, the edge gateway can automatically send the device data stored in the internal memory to the server through the second interface in the power-on state, the automatic transmission of the device data of the non-networking device is achieved, manual participation is not needed, and the data transmission efficiency is improved.
For example, in S120, "if it is detected that the preset data transmission condition is currently met, power is supplied to the first interface, the second interface of the internal memory is powered off, and the device data in the internal memory is transmitted to the server through the second interface in the powered-on state" may include: and responding to a data acquisition instruction sent by the server or detecting that the current timing time is reached, powering off the first interface, supplying power to the second interface of the built-in memory, and sending the equipment data in the built-in memory to the server through the second interface in the power-on state.
The data obtaining instruction may refer to that the server sends the data obtaining instruction after the external device completes at least one data update. The timing time may refer to a timing interval that needs to be greater than a maximum length of time required for a single time that the device data is stored in the built-in memory.
Specifically, after the device data is stored in the internal memory, the edge gateway may power off the first interface by responding to a data acquisition instruction sent by the server or detecting that the current time reaches a set time, so that the internal memory may store the device data for multiple times, and supply power to the second interface of the internal memory, so that a controller of the internal memory switches from the external device to the edge gateway, and automatically sends the device data stored in the internal memory for multiple times to the server through the second interface in a power-on state, thereby implementing batch uploading of the device data, and saving data transmission resources.
According to the technical scheme of the embodiment of the invention, the edge gateway is additionally provided with the built-in memory with double interfaces, and the edge gateway is connected with the non-networked external equipment through the first interface of the built-in memory, so that the external equipment realizes automatic transmission of equipment data through the edge gateway. Specifically, the edge gateway may supply power to the first interface when receiving a data storage instruction sent by the server, so that the external device may control the internal memory, and the external device may automatically store the device data into the internal memory through the first interface in the power-on state. If the edge gateway detects that the preset data sending condition is met currently, the first interface is powered off, and power is supplied to the second interface of the built-in memory, so that a controller of the built-in memory is switched from the external device to the edge gateway, the edge gateway can automatically send the device data stored in the built-in memory to the server through the second interface in the power-on state, the automatic transmission of the device data of the non-networking device is achieved, manual participation is not needed, and the data transmission efficiency is improved.
On the basis of the above technical solution, after S120 "transmitting the target device data in the built-in memory to the server", the method further includes: and powering off the second interface to stop the data transmission operation of the edge gateway.
Specifically, the edge gateway may automatically send the target device data in the internal memory to the server, and then power off the second interface to stop the data sending operation of the edge gateway, where the first interface and the second interface are both in a power-off state, so as to avoid uninterrupted data sending operation by the edge gateway, further save data transmission resources, and ensure validity of data transmission.
Example two
Fig. 2 is a flowchart of a data transmission method according to a second embodiment of the present invention, where in this embodiment, further optimization is performed on the step "if it is detected that a preset data sending condition is currently met, power is supplied to the first interface, the second interface of the internal memory is powered on, and the device data in the internal memory is sent to the server through the second interface in the powered on state. Wherein explanations of the same or corresponding terms as those of the above-disclosed embodiments are omitted. As shown in fig. 2, the method may include the steps of:
s210, responding to a data storage instruction sent by the server, supplying power to the first interface, so that the external device stores the device data into the internal memory through the first interface in the power-on state.
And S220, if the current data storage is detected to be finished, powering off the first interface, supplying power to the second interface of the built-in memory, and sending the device data stored in the built-in memory at the current time to the server through the second interface in the power-on state.
Specifically, in the process of storing the device data into the built-in memory, the edge gateway may detect whether the data storage of the built-in memory is completed. If the current data storage is not completed, the first interface is kept in a power-on state, and at the moment, the external device is still a controller of an internal memory in the edge gateway until the current data storage is completed, so that the condition that the device data is uploaded to a server without being completely stored in the internal memory is avoided, the device data is prevented from being damaged, and the accuracy and the integrity of the device data are further ensured. And if the data storage is finished at the current time, powering off the first interface and supplying power to the second interface of the built-in memory, so that a controller of the built-in memory is switched from the external device to the edge gateway, and automatically transmitting the device data stored in the built-in memory to the server through the second interface in a power-on state.
Exemplarily, the "detecting that the current data storage is completed" in S220 may include: acquiring electrical frequency data corresponding to a first interface; and if the electric signal in the electric frequency data is detected to be weakened to zero, determining that the data storage is finished at the time.
The electrical data may be used to determine a data transmission status of the corresponding interface. For example, when data starts to be transmitted, the electrical signal in the electrical frequency data starts to be enhanced from zero; when the data transmission is about to end, the electric signal in the electric frequency data is weakened to zero.
Specifically, the edge gateway may obtain the electrical frequency data corresponding to the interface through the functional module connected to the first interface, and determine that the data storage is completed at this time if it is detected that the electrical signal in the electrical frequency data is weakened to zero, thereby avoiding an error caused by manually confirming whether the data transmission is completed, and further improving the accuracy of the data transmission.
According to the technical scheme, whether the data storage of the built-in memory is finished or not can be detected through the edge gateway, if the data storage of the built-in memory is finished, the first interface is powered off, and the second interface of the built-in memory is powered on, so that a controller of the built-in memory is switched to the edge gateway from the external device, and the equipment data stored in the built-in memory is automatically sent to the server through the second interface in a power-on state, the condition that the equipment data are uploaded to the server when not completely stored in the built-in memory is avoided, the equipment data are not damaged, the accuracy and the integrity of the equipment data are further ensured, meanwhile, the equipment data generated at each time are uploaded to the server in time, and the timeliness of the data is ensured.
