In accordance with an embodiment of the present invention, there is provided a method embodiment of a data transmission method for a wireless device, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 2 is a flowchart of a data transmission method of a wireless device according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S202, determining the residual electric quantity of a plurality of wireless devices installed at a plurality of different positions;
step S204, adjusting the installation position of each wireless device according to the residual electric quantity of the plurality of wireless devices and the communication quality at different positions;

and step S208, controlling the non-target equipment to transmit the acquired data to the target equipment, and forwarding the data to the communication base station through the target equipment.
Determining the residual electric quantity of a plurality of wireless devices installed at a plurality of different positions; adjusting the installation position of each wireless device according to the residual electric quantity of the plurality of wireless devices and the communication quality at different positions; determining the wireless equipment at the position where the communication quality exceeds a preset threshold value as target equipment, and determining the wireless equipment at the position where the communication quality does not exceed the preset threshold value as non-target equipment; the non-target equipment is controlled to transmit the acquired data to the target equipment, and the wireless equipment with high communication quality and large residual electric quantity is arranged at the position with better signal in a mode of transmitting the data to the communication base station by the target equipment, is used as the target equipment, not only undertakes the data transmission of the self equipment and the communication base station, meanwhile, the wireless communication system is used as a transfer device for data transmission between non-target devices at other positions with poor signals and a communication base station, so that the aim of improving the communication quality of all the wireless devices of the whole system by adjusting the positions of the wireless devices and utilizing the adjusted target devices is fulfilled, thereby realizing the technical effects of reducing the loss of communication resources and improving the utilization rate of the communication resources, and further solve the technical problem that the communication loss is large due to poor signal quality of wireless equipment or low utilization rate in the related art.
The wireless equipment can be wireless monitoring equipment, collects monitoring video in real time, transmits the monitoring video to the communication base station in a wireless transmission mode, transmits the monitoring video to the network through the communication base station, and provides a remote terminal to check the monitoring video through the network. However, because the communication signal between the wireless device and the base station is unstable, the data transmission efficiency between some wireless devices and the communication base station is low, which results in transmitting the signal with a large transmission power for a long time and a large power consumption. Or some wireless devices have good communication signals and high data transmission efficiency, but the data volume is small, the service time is short, and the power consumption is wasted.
In this embodiment, the remaining power of a plurality of wireless devices installed at different locations may be used to determine the power consumption of the wireless device, and in short, the larger the remaining power, the longer the duration of data transmission at a higher transmission power. And adjusting the wireless equipment with larger residual power to the position with good communication quality according to the communication quality of the wireless equipment at each position. The target device with large residual electric quantity can transmit data of the device and other devices with good communication quality, and other non-target devices can communicate in a communication mode with small power consumption among wireless devices, so that the power consumption of other non-target devices with small residual electric quantity is saved, and high-quality communication between all wireless devices and a communication base station can be guaranteed.
The target device is a wireless device at a position where the communication quality exceeds a preset threshold, and the non-target device is determined as a non-target device at a position where the communication quality does not exceed the preset threshold. The number of the target devices may be one or more, and the specific number may be determined according to an average transmission rate of the total amount of data transmission of all the wireless devices. For example, the data transmission rates of a plurality of target devices and the communication base station are all a, the average transmission rate of the total data transmission amount of all the wireless devices is b, and b is greater than a, so that one target device cannot meet the transmission requirements of all the wireless devices, and at least two target devices need to be set to forward the data of all the wireless devices to the communication base station.
It should be noted that, if the communication quality of the target device exceeds the preset threshold, it may prove that the target device has a capability of continuously transmitting data to the communication device at a high power, but the number of devices with the transmission capability may be multiple, and the devices need to perform data forwarding may actually be only a part of the multiple target devices with the capability. Therefore, the target device with sufficient electric quantity can be preferentially selected as the forwarding device, and the data of other non-target devices can be forwarded to the communication base station.
Theoretically, the forwarding device can also forward data of other target devices, but the other target devices have good communication quality and sufficient residual electric quantity, and can completely meet the data transmission requirements of the forwarding device, so that the forwarding device only forwards the data of the non-target devices, the load and power consumption of the forwarding device can be reduced, and effective data transmission between all wireless devices and the communication base station can be ensured.
The target device with the highest residual electric quantity in the multiple target devices is determined as the forwarding device, and in implementation, the forwarding authority can be given to the target device to forward data of other non-target devices. When the forwarding device continuously works and consumes the power rapidly, the residual power of the forwarding device is detected, and when the residual power of the forwarding device is lower than that of other target devices with the capacity, the forwarding authority can be given to other target devices with the highest residual power. Therefore, the phenomenon that the wireless equipment of the forwarding equipment cannot work quickly due to long-time quick consumption of the forwarding equipment is avoided. Affecting the operation of the entire wireless device system.
Optionally, before adjusting the installation location of each wireless device according to the remaining power of the plurality of wireless devices and the communication quality at different locations, the method further includes: the method comprises the steps of collecting communication signals of each wireless device, and determining communication parameters corresponding to the communication signals, wherein the communication parameters at least comprise: signal-to-noise ratio and available resource percentage; and determining the communication quality of the position where each wireless device is positioned according to the communication mode and the communication parameters of each wireless device.
Before adjusting the installation location of each wireless device according to the remaining power of the wireless device and the communication quality at different locations, the communication quality at each location needs to be determined. Specifically, the method includes collecting communication signals of each wireless device, and determining communication parameters corresponding to the communication signals, where the communication parameters at least include: signal-to-noise ratio and available resource percentage; and determining the communication quality of the position where each wireless device is positioned according to the communication mode and the communication parameters of each wireless device. Since the plurality of wireless devices usually use the same type of wireless device in the same batch, the performance of the wireless devices is close, and the communication quality of the wireless device at the position can represent the communication quality at the position. Thereby determining the communication quality of the location based on the communication quality of the wireless device at each location before adjustment.
Specifically, determining the communication quality of the position where each wireless device is located according to the communication mode and the communication parameters of each wireless device includes: calculating communication quality by the following formula; q is a × b, where Q is communication quality, a is a quality coefficient of a communication mode of the wireless device at the location, b is a communication parameter of the wireless device at the location, b is x × r, x is a signal-to-noise ratio of a communication signal of the wireless device at the location, and x is a percentage of available resources of the communication signal of the wireless device at the location.
In the case that the wireless device is a wireless monitoring device, the operation modes of the wireless monitoring device may include a 5G-SA operation mode, a 5G-NSA operation mode, a 4G-FDD operation mode, a 4G-TDD operation mode, a 3G operation mode, a 2G operation mode, and a non-operation mode of NO signal NO SERVICE. The corresponding mass coefficients a are 0.95, 0.9, 0.7, 0.62, 0.4, 0.3 and 0, respectively.
The communication parameters are used for reflecting communication quality, and may also include parameters such as data transmission efficiency and frame loss degree of transmission. The communication quality may be determined in this embodiment based on the signal-to-noise ratio and the percentage of available resources. I.e. Q ═ a × x r.
Optionally, after controlling the non-target device to transmit the acquired data to the target device and forwarding the data to the communication base station through the target device, the method further includes: determining the number of target devices; monitoring the residual electric quantity of forwarding equipment with forwarding authority in the target equipment under the condition that the number of the target equipment is multiple, wherein the forwarding equipment is the target equipment with the maximum residual electric quantity in the multiple target equipment; and under the condition that the residual capacity of the forwarding equipment meets the replacement condition, taking the target equipment with the highest residual capacity as the updated forwarding equipment.
If the communication quality of the target device exceeds the preset threshold, it indicates that the target device has the capability of data forwarding, and there may be a plurality of target devices with the capability of data forwarding in the plurality of wireless devices. The target device with the largest remaining power among the plurality of target devices is selected as the forwarding device as described above. It should be noted that the number of the forwarding devices may be one or several target devices with the largest remaining power.
And monitoring the residual electric quantity of the forwarding equipment in real time, and taking the target equipment with the highest residual electric quantity as the updated forwarding equipment under the condition that the residual electric quantity meets the replacement condition so as to avoid the condition that the forwarding equipment cannot work due to long-time high-power-consumption work of the forwarding equipment.
Optionally, when the number of the target devices is multiple, monitoring the remaining power of the forwarding device having the forwarding right in the target devices includes: determining the consumption electric quantity of the current electric quantity of the forwarding equipment relative to the initial electric quantity, wherein the initial electric quantity is the residual electric quantity when the forwarding equipment is started to be used; determining that the residual electric quantity of the forwarding equipment meets a replacement condition under the condition that the consumed electric quantity reaches a preset difference value; or, determining the current residual capacity of the forwarding equipment; and under the condition that the current residual capacity of the forwarding device is lower than the wireless device with the highest residual capacity in the target device, determining that the residual capacity of the forwarding device meets the replacement condition.
For example, the remaining capacities of two target devices having the highest remaining capacity among the plurality of target devices are 10000mAh and 8000mAh, respectively, and the number of the forwarding devices is one, the target device having the remaining capacity of 10000mAh is set as the forwarding device.
If the power consumption is 3000mAh and meets the replacement condition, and if it is monitored that the remaining power of the forwarding device is 6500mAh, the power consumption is 10000 and 6500, i.e., 3500mAh and greater than 3000mAh, the replacement condition is met, the forwarding authority of the forwarding device is transferred to the target device of 8000mAh, and the target device is used as a new forwarding device.
Or, when the current remaining power of the forwarding device is 7800mAh and is smaller than 8000mAh with the highest remaining power of other target devices, it can be determined that the forwarding device meets the replacement condition, the forwarding authority of the forwarding device is transferred to the target device with 8000mAh, and the target device is used as a new forwarding device.
Optionally, controlling the non-target device to transmit the acquired data to the target device, and forwarding the data to the communication base station through the target device includes: determining whether the buffer amount of the data of the non-target equipment reaches a preset threshold value; and under the condition that the buffer amount of the data of the wireless equipment reaches a preset threshold value, the buffered data is packaged and transmitted to the target equipment, and the data is sent to the communication base station through the target equipment.
The communication mode between the non-target device and the target device may be D2D communication, and in order to ensure communication quality and reduce power consumption, data collected by the non-target device may be cached locally first, and when the replacement quantity of the cached data reaches a preset threshold, the data may be transmitted to the target device once again, and the data may be forwarded to the communication base station by the target device. Therefore, transmission can ensure that the power consumption of the non-target equipment is reduced, the non-target equipment is not required to continuously send data, and the target equipment needs to forward the data of a plurality of non-target equipment, so that the non-target equipment transmits at intervals, the interference generated by data transmission with other non-target equipment is avoided, and the error probability of data transmission is reduced.
Optionally, adjusting the installation position of each wireless device according to the remaining power of the plurality of wireless devices and the communication quality at different positions includes: determining the wireless equipment to be replaced, the residual electric quantity of which is not matched with the installation position, according to the communication quality at different positions; determining a replacement position matched with the wireless equipment to be replaced according to the sequence of the residual electric quantity of the plurality of wireless equipment and the sequence of the communication quality; according to the wireless device to be replaced and the replacement position, the wireless device to be replaced is prompted to be replaced to the replacement position, so that all the wireless devices are installed on the matched positions.
When the position is adjusted, the communication qualities of a plurality of positions can be sorted according to the quality of the communication qualities, the optimal front is arranged, the worst rear is arranged, the residual electric quantities of a plurality of wireless devices are sorted according to the residual electric quantities, the most front is arranged, the least rear is arranged, so that the positions and the wireless devices can be matched, the positions where the positions are located and the matched positions are determined to be not in line with the wireless devices, and the wireless devices are installed on the matched positions.
Specifically, under the condition that the wireless device and the position are not matched, the prompting lamp of the wireless device is controlled to flicker. Meanwhile, the indicator light of the wireless device which is installed at the current position matched with the wireless device is controlled to flash, so that an operator is prompted to replace the wireless device and the wireless device, the wireless device is installed at the matched position, the wireless device which is installed at the matched position is controlled to send out another prompt for installing the wireless device at the matched position, for example, the green light is controlled to be normally on, the operation is circulated until all the wireless devices are normally on, and all the wireless devices are also installed at the matched position.
It should be noted that the present application also provides an alternative implementation, and the details of the implementation are described below.
In this embodiment, a method and a system for reducing power consumption and cost of a 5G device are used to reduce overall power consumption of a cellular module, and a main design method is as follows:
