The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the data transmission control method provided in the embodiment of the present application is generally executed by an internet of things terminal, and accordingly, the data transmission control device is generally configured in the internet of things terminal.
Referring to fig. 1, fig. 1 shows an embodiment of a data transmission control method.
It should be noted that, if the result is substantially the same, the method of the present invention is not limited to the flow sequence shown in fig. 1, and the method includes the following steps:
s1: and if the data transmission failure is monitored, acquiring the current signal information of the terminal equipment, wherein the signal information comprises signal strength and signal-to-noise ratio.
In the embodiment of the present application, in order to more clearly understand the technical solution, the internet of things terminal related to the present application is described in detail below.
The Internet of things terminal comprises a Micro Control Unit (MCU) and a data transmission unit, wherein the micro control unit controls data acquisition, data transmission and other behaviors of the data transmission unit, and is connected with the data transmission unit through a serial port to realize data transmission behaviors such as uploading and downloading of data. The data transmission unit is a communication module, a communication public board or a data transmission terminal and is connected with the micro control unit through a serial port. Meanwhile, the data transmission unit can collect data and can also acquire the network signal intensity and the signal-to-noise ratio of the current terminal equipment through an attached network.
Specifically, if the data transmission unit does not receive the confirmation information within the preset time, it indicates that the data transmission is failed. The reason for the data transmission failure is often related to the signal strength and the signal-to-noise ratio of the current internet of things terminal, so that if the data transmission failure is monitored, the current signal information of the internet of things terminal is obtained. The SIGNAL-to-NOISE RATIO is called SNR or S/N (SIGNAL-to-NOISE RATIO), which is also called SIGNAL-to-NOISE RATIO, and refers to the RATIO of SIGNAL to NOISE in an electronic device or electronic system.
Referring to fig. 2, fig. 2 shows an embodiment of step S1, which is described in detail as follows:
s11: and if the data transmission failure is monitored, recording the data transmission failure times.
Specifically, by recording the number of data transmission failures, it is convenient to determine whether the data needs to be retransmitted. If the data transmission failure times are too large, the current network environment is not suitable for transmitting data, and the data transmission is stopped.
S12: and attaching the network through a data transmission unit to acquire the current signal strength and signal-to-noise ratio.
Specifically, the data transmission unit is attached to the network, so that the current signal strength and signal-to-noise ratio of the terminal device are obtained, the current network environment is judged, and the retransmission time threshold value is conveniently obtained.

S1A: and sending a data uploading instruction to the data transmission unit through the micro control unit.
S1B: and collecting data based on the data transmission unit and transmitting the data.
S1C: and monitoring the data transmission state corresponding to the data.
Further, the data transmission according to the embodiment of the present application satisfies an Automatic Repeat reQuest (ARQ) protocol, where the ARQ protocol is an Automatic Repeat reQuest (ARQ) protocol that automatically issues a reQuest for retransmitting an error frame when a receiving station receives a message (frame) containing error data. In the embodiment of the application, data is transmitted, after transmission fails, a retransmission time threshold is obtained, and the data is retransmitted within the retransmission time threshold until the data is transmitted successfully or the retransmission time reaches the retransmission time threshold. Therefore, in the embodiment of the application, when data is transmitted, whether the data is transmitted successfully is judged by monitoring the data transmission state.
Specifically, because thing networking terminal includes little the control unit and data transmission unit, should be for the control unit can send data upload instruction to data transmission unit, after data upload instruction was received to data transmission unit, by data transmission unit collection data to transmit data. Meanwhile, in the data transmission process, the transmission state of the data is monitored. According to the embodiment, data collection and transmission are achieved, the data transmission state is monitored, the data transmission state is obtained, and follow-up retransmission of data transmission failure is facilitated.
Referring to fig. 4, fig. 4 shows an embodiment of step S1C, which is described in detail as follows:
and S1C1, if the data transmission unit is monitored to receive the confirmation information within the preset time, the data transmission is successful.
And S1C2, if the data transmission unit does not receive the confirmation information within the preset time, the data transmission fails.
Specifically, the acknowledgement message is also called an ACK message, which is a part of a communication protocol in a computer network, and is a message sent by a device or a process to reply to a received data; acknowledgement messages are used in ARQ (automatic repeat request) protocols, where acknowledgement frames are numbered in coordination with received frames and sent back to the terminal device, which knows whether there are any missing packets. In the embodiment of the application, since the terminal of the internet of things generates the confirmation message when receiving the data and feeds the message back to the data transmission unit, whether the terminal of the internet of things sends the confirmation message to the data transmission unit is monitored to realize monitoring of the transmission state of the data.
Specifically, if the data transmission unit receives the confirmation information within the preset time, it indicates that the internet of things terminal has received complete data at this time, the data transmission is successful, and if the data transmission unit does not receive the confirmation information within the preset time, the data transmission is failed.
The preset time is set according to actual conditions, and is not limited herein. In one embodiment, the predetermined time is 5 minutes.
Specifically, whether the data transmission unit receives the confirmation information or not is monitored by the monitor within the preset time so as to confirm the data transmission state, and therefore whether data needs to be retransmitted or not is judged, and the data transmission success rate is increased.
S2: and acquiring a retransmission time threshold value based on the comparison result of the signal information and a preset retransmission relation table.
The preset retransmission relation table is set according to actual conditions, and is not limited here. In one embodiment, the table of predetermined retransmission relationships is shown in table 1 below:
| signal strength RSRP | SNR | Threshold of number of retransmissions |
| -105dBm and above | 3db and above | 2 |
| -105dBm to-115 dBm | -2 to 0db | 3 |
| -115dBm and below | -2db to-3 db | 4 |
