Therefore, a transmission link for independently transmitting the first data does not need to be maintained, so that interfaces needing back-end maintenance can be reduced, and workload and labor cost are reduced.
Referring to fig. 2, fig. 2 is a block diagram of the transmission apparatus 100 in fig. 1. The transmission device 100 may include a memory 110, a processor 120, and a communication unit 130.

For example, the memory 110 stores the data transmission device 300, and the data transmission device 300 includes at least one software functional module which can be stored in the memory 110 in the form of software or firmware (firmware). The processor 120 executes various functional applications and data processing, i.e., implements the data transmission method in the embodiment of the present application, by running software programs and modules stored in the memory 110, such as the data transmission device 300 in the embodiment of the present application.
The communication unit 130 is used to establish a communication connection between the transmission apparatus 100 and another communication terminal through a network, and to transceive data through the network.
It should be understood that the configuration shown in fig. 2 is merely a schematic configuration of the transmission apparatus 100, and that the transmission apparatus 100 may also include more or fewer components than shown in fig. 2, or have a different configuration than shown in fig. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 3, fig. 3 is a schematic flowchart of a data transmission method according to an embodiment of the present application. The method may be applied to the transmission apparatus 100. The specific flow of the data transmission method is described in detail below. The method may include steps S110 to S130.
Step S110, first data is obtained.
Step S120, inserting the first data into the second data to be transmitted, to obtain third data.
Step S130, sending the third data to the first device through the transmission link corresponding to the second data.
In this embodiment, the transmission device 100 may determine the first data and the second data to be transmitted to the first device in any manner. Optionally, the first data and the second data may be both data that needs to be transmitted in real time, or may not be data that needs to be transmitted in real time, and may be determined specifically according to an actual situation. The first data and the second data are of different types, where the different types refer to that, when one type of data is transmitted by using a transmission link, the transmission links corresponding to the first data and the second data are different.
And under the condition that the first data and the second data are determined, inserting the first data into the second data to obtain the third data. And then, transmitting the third data to the first equipment by using the transmission link corresponding to the second data. The first device 200 may obtain the first data and the third data by analyzing the third data.
Therefore, the existing interface is not required to be changed, one transmission link can transmit two different types of data simultaneously, the transmission link for independently transmitting the first data is not required to be maintained, the interface required to be maintained by the rear end can be reduced, and the workload and the labor cost are reduced.
In this embodiment, the transmission device 100 may be communicatively coupled to a second device. The transmission apparatus 100 may obtain the first data through the second apparatus. For example, the second device may send the first data to the transmission device, so that the transmission device obtains the first data.
The second device may be a device for data acquisition, for example, the second device is a device including a sensor, and data may be collected by the transmitter to obtain the first data. For example, the second device may be a liquid level meter comprising a liquid level sensor by which liquid level data may be collected to obtain said first data. The first data obtained by the transmission device 100 may be in a first preset format, and the first preset format may be a format supported by the first device 200, for example, a json format, which may be specifically determined by the first device 200.
Alternatively, the second device may summarize and summarize the collected data, arrange the summarized and summarized data into first data in a predetermined format, and then send the first data to the transmission device 100. Alternatively, the summarized and summarized data is arranged into the first data of the prescribed format by the transmission device 100. The prescribed format may be a first preset format supported by the first device 200.
The transmitting device 100 may select another data to be transmitted as the second data. And then converting the format of the first data from the first preset format into a second preset format, and further inserting the first data in the second preset format into the second data to obtain the third data. The second preset format is a format used by the second data, that is, a format used when the second data is transmitted through a transmission link corresponding to the second data. The second predetermined format may be determined by the specific second data, for example, hexadecimal. Therefore, the first data and the second data are mixed together conveniently and are sent through the transmission link corresponding to the second transmission.
Optionally, when inserting the first data, a preset mark may be inserted into the second data together with the first data as a whole, so as to identify the position of the first data in the third data. The specific insertion positions of the preset mark and the first data can be set according to actual requirements. For example, the preset mark and the first data are sequentially inserted at the end of the second data, so that when the first device 200 parses the preset mark, it is determined that the subsequent data is the first data. Wherein the preset mark comprises at least one character string. To avoid mistakenly taking other data as the first data, the preset flag may include a plurality of character strings, for example, when the second preset format is hexadecimal, the preset flag may be: 0x7b, 0x0a, 0x09, 0x22, 0x64, 0x61, 0x74, 0x61, 0x 22.
Optionally, as a possible implementation manner, the first data in the second preset format may be divided to obtain a plurality of data subsets. The specific division manner can be determined by actual conditions. Such as an average score, or otherwise. After the division, each data subset and a preset mark may be sequentially inserted into the second data to obtain the third data. Wherein each data subset and the preset mark are inserted into the second data as a whole. The insertion location of each subset of data is different. Thus, when it is inconvenient to insert the first data into the second data as a whole, the first data can be inserted into the second data in the above-described manner.
Optionally, when the data subsets are inserted, the data subsets and the preset marks may be inserted into the second data in sequence according to positions of the data subsets in the first data. For example, if the first data sequentially includes the data subset 1, the data subset 2, and the data subset 3, the data subset 1 and the preset mark may be inserted into the position a of the second data, then the data subset 2 and the preset mark may be inserted into the position b of the second data, and finally the data subset 3 and the preset mark may be inserted into the position c of the second data. Where b is located between a and c, and reaches a, b, and c in order when performing analysis. Therefore, the complete first data can be reconstructed quickly after analysis.
Optionally, if the second data is video data, the predetermined flag and the data subset may be inserted into the end of a frame of data, so as to facilitate subsequent fast capture of the first data.
After the insertion is completed, the transmission apparatus 100 may transmit the third data to the first apparatus 200. The first device 200 may analyze the third data based on an analysis manner corresponding to the second data in the second preset format to obtain the first data and the second data. And when analyzing, the first data and the second data can be analyzed from the third data according to the preset mark.
Since the format of the directly parsed first data is the second preset format, the first device 200 may further convert the format of the directly parsed first data from the second preset format to the first preset format, so as to obtain the first data in the first preset format.
In this embodiment, in a possible implementation manner, the first data is non-video data, for example, data that needs to be transmitted in real time and is acquired by the second device; the second data is video data, for example, RTSP (real time streaming protocol) video stream. Therefore, the non-video data and the video data can be transmitted simultaneously through the transmission link corresponding to the video data.
In this implementation, the transmission device 100 may sequentially insert each data subset and the preset flag into the end of a partial frame in the second data to obtain the third data; and then exchanging data through an interface to send the third data to the first device. The first device 200 may parse each frame of data in the third data, and when parsing that one frame of data includes the preset mark, may intercept data from the preset mark until the end of the frame of data; and repeating the operation on each frame of data to obtain the intercepted data. For example, in the hexadecimal data included in each frame of data, data beginning with 0x7b, 0x0a, 0x09, 0x22, 0x64, 0x61, 0x74, 0x61, 0x22 may be searched, and if the data is found, data interception is performed from the data point of 0x7b until the end of the frame of data; after the third data is processed, the intercepted data corresponding to the first data can be obtained.
All intercepted data in the second preset format obtained from the third data in the mode are first data in the complete second preset format. Then, the format of the first data obtained by data interception can be converted from the second preset format to the first preset format through format conversion. As shown in fig. 4, the first data of the first preset format shown in fig. 4 may be finally obtained.
Under the condition of obtaining first data in a first preset format and second data in a second preset format, the first device 200 may update the display content in the display interface according to an actual requirement by combining the first data and the second data.
For example, the second device may obtain the first data as real-time data through data acquisition, for example, the second device may acquire sensor data included in the real-time data at a certain acquisition frequency to obtain the first data; in case the first data, which is real-time data, is obtained, the first data may be forwarded to the first device 200 via the transmitting device 100. The first device 200 may extract key data (for example, at least a part of the sensor data) in the obtained first data in the first preset format, and assign a value to a place where the data needs to be displayed in the display interface according to the key data, so as to display the key data in real time. For example, the sensor data may include liquid level data obtained by a liquid level sensor, and as shown in fig. 5, the liquid level data as key data may be assigned to a place where the liquid level needs to be displayed, so as to display the liquid level in real time. Therefore, the first device 200 can update the display content in the display interface in real time by combining the real-time data sent by the second device, so as to realize real-time display of the data, thereby achieving the effect of optimizing the user experience.
Therefore, when the first data is real-time data which needs to be transmitted by using a socket long link and the second data is an RTSP video stream, the first data can be inserted into the second data to be transmitted by the above mode of the application, so that the live stream and the data stream are simultaneously supported on the basis of not changing the existing interface, the purpose of long-time real-time data transmission can be achieved, and a plurality of interfaces do not need to be maintained.

In step S240, the first device 200 parses the received third data to obtain the first data and the second data.
Optionally, in this embodiment, the third data may include a preset mark corresponding to the first data, where the preset mark is used to identify a position of the first data, and the preset mark includes at least one preset character string. The first device 200 may parse the first data and the third data from the third data according to the preset mark.
Optionally, in this embodiment, the second data is video data in a second preset format. The first device 200 parses each frame of data in the third data, and when parsing a frame of data includes the preset mark, may intercept data from the preset mark until the end of the frame of data to obtain intercepted data. And then carrying out format conversion on the intercepted data in the second preset format obtained from the third data to obtain first data in the first preset format.
