Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides an information processing scheme, which can determine a first transmission quality parameter and a second transmission quality parameter according to a signal received by first equipment, and further predict whether communication connection between the first equipment and the second equipment is about to be disconnected according to the first transmission quality parameter; under the condition that the communication connection is about to be disconnected, the prompt message of the communication connection about to be disconnected is output to realize disconnection early warning, so that a user is facilitated to prepare before the communication connection is disconnected, and the problems of communication data loss and the like caused by sudden disconnection of the communication connection are avoided. In addition, the prompt information can also include a reason that the communication connection is about to be disconnected, and a corresponding control scheme can be adopted to control the operation of the first equipment according to the reason included in the prompt information so as to avoid the disconnection of the communication connection, thereby reducing the probability of the disconnection of the communication connection and improving the operation safety of the first equipment or the second equipment.
Based on the above information processing scheme, the embodiment of the invention provides an information processing system. Referring to fig. 1, a schematic structural diagram of an information processing system according to an embodiment of the present invention is provided, where 101 represents a first device, 102 represents a second device, and 103 represents a communication link between the first device 101 and the second device 102. A communication connection is established between the first device 101 and the second device 102. The first device 101 may include any one of a movable platform or a control device, the second device 102 may include any one of a movable platform or a control device, and the first device 101 and the second device 102 are different devices, in fig. 1, it is assumed that the first device 101 is a movable platform, such as an unmanned aerial vehicle, and the second device 102 is a control device of the first device, such as a remote controller.
In the information processing system described in fig. 1, the second device 102 may send a control instruction, such as an instruction to control the first device 101 to fly or an instruction to collect an image, to the first device 101 based on the communication connection, and the first device 101 may send a service execution result, such as a collected image or voice, to the second device 102 based on the communication connection.
If the communication connection between the first device 101 and the second device 102 is broken, the first device 101 is in an out-of-step state, that is, the first device 101 cannot receive the control instruction sent by the second device 102, which easily causes a flight safety problem of the first device 101. Therefore, in the information processing system described in fig. 1, the scheme of the above information processing may be adopted to implement prediction of whether the communication connection is about to be disconnected, and in case that the communication connection is predicted to be disconnected, the prompt information carrying the reason of the disconnection is output so as to control the first device 101 to start a flight scheme for avoiding the disconnection of the communication connection according to the prompt information, thereby ensuring the flight safety of the first device 101.
Based on the above information processing system, the embodiment of the invention provides an information processing method. Referring to fig. 2, a flow chart of an information processing method according to an embodiment of the present invention is provided, where the information processing method shown in fig. 2 may be applied to a first device, a communication connection is established between the first device and a second device, and the first device and the second device may mutually transmit signals based on the communication connection. The information processing method described in fig. 2 may be executed by the first device, and in particular, may be executed by a processor of the first device, and the following steps are shown in fig. 2:
Step S201, determining a first transmission quality parameter and a second transmission quality parameter according to a signal received by the first device.
The signal received by the first device may include the signal sent by the second device, and the signal received by the first device may also include interference signals or noise of other devices. Alternatively, the first device may include a movable platform, such as a drone or a robot, and the second device may include a control device corresponding to the first device, such as a remote control of the movable platform. Alternatively, the second device may include a movable platform, and the first device includes a control device corresponding to the first device.
In one embodiment, the first transmission quality parameter may include any one or more of: packet error rate (Packet Error Rate, PER) and carrier to interference plus noise ratio (Carrier to Interference and Noise Ratio, CINR); the second transmission quality parameter may comprise any one or more of: a signal received strength indication (Received Signal Strength Indicator, RSSI) and a reference signal received power (Reference Signal Received Power, RSRP).
It should be understood that the signal received by the first device may include an effective signal and a noise signal (where the noise floor and the interference signals of other devices are collectively referred to as noise signals), the packet error rate PER may be understood as a proportion of all data packets included in the received signal that are erroneous, the reference signal power RSRP may be understood as a received power of the effective signal, the signal received strength indication RSSI may be understood as a strength of the received signal including the effective signal and the noise signal, and the carrier to interference and noise ratio CINR may be understood as a ratio of the received power of the effective signal to the received power of the noise signal.
In one embodiment, the determining the first transmission quality parameter and the second transmission quality parameter according to the signal received by the first device includes: and processing baseband information of the signal received by the first equipment by adopting a baseband information identification technology to obtain a first transmission quality parameter and a second transmission quality parameter.
Step S202, predicting whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter.
It should be appreciated that the first device and the second device transmit signals based on a communication connection between the first device and the second device. For example, the first device is an unmanned plane, the second device is a control device, and the second device may send a control signal to the first device, such as a signal for controlling the second device to fly, based on a communication connection between the two devices; similarly, the first device may send a real-time graphical signal of the drone to the second device based on the communication connection between the two. If the communication connection between the first device and the second device is disconnected, the first device cannot receive the control signal, and the second device cannot receive the real-time image transmission signal, so that flight safety is easily affected. Therefore, in order to ensure the safe operation of the equipment, the embodiment of the invention can predict whether the communication connection is about to be disconnected according to the first transmission quality parameter, and if the communication connection is about to be disconnected, the prompt information about the connection to be disconnected can be output so as to enable the first equipment to start an automatic relief scheme or remind a user of the first equipment or the second equipment to take relief measures, thereby reducing the probability of disconnection of the communication connection and ensuring the operation safety of the equipment.
In one embodiment, the first transmission quality parameter includes a packet error rate PER, and predicting whether the communication connection between the first device and the second device is about to be broken according to the first transmission quality parameter includes: predicting whether the communication connection between the first device and the second device is about to be disconnected according to the packet error rate set in the target time. The target time may be any time period specified by the first device.
As an optional embodiment, said predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of packet error rates within the target time comprises: acquiring a first number of packet error rates greater than a packet error rate threshold among a plurality of packet error rates included in the packet error rate set; if the first number is greater than or equal to a first number threshold, predicting that a communication connection between the first device and the second device is about to be disconnected.
The first number threshold may be determined by a proportion of the tolerable packet error rate in the set of packet error rates greater than the packet error rate threshold in the case of communication connection. Assuming that the proportion of the packet error rate greater than the packet error rate threshold in the preset packet error rate set is 70%, the communication connection between the first device and the second device is predicted to be disconnected. The first number threshold may be determined based on a total number of packet error rates included in the set of packet error rates and a proportion of the packet error rates greater than the packet error rate threshold of 70%. For example, if the total number of packet error rates included in the packet error rate set is 100, the first number threshold may be 100×70+=70.
Alternatively, the tolerable packet error rate varies for different transmission services, and thus the packet error rate threshold varies according to the transmission services.
Alternatively, the packet error rate greater than the packet error rate threshold may be the packet error rate at consecutive time instants, or may not be the packet error rate generated at consecutive time instants. For example, the set of packet error rates includes 5 packet error rates, PER1, PER2, PER3, PER4, and PER5 in order of time generated by the packet error rates, and assuming that the first number of packet error rates greater than the packet error rate threshold is 3, the 3 packet error rates may be packet error rates at consecutive times such as PER1, PER2, PER3; alternatively, the 3 packet error rates may not be the packet error rates of consecutive instants such as PER2, PER4, and PER5.
As another alternative embodiment, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of packet error rates in the target time includes: performing differential processing on a plurality of packet error rates included in the packet error rate set to obtain the packet error rate increasing speed in the target time; and if the packet error rate increasing speed is greater than or equal to a first speed threshold, predicting that the communication connection between the first equipment and the second equipment is about to be disconnected. The first speed threshold may be preset, and the first speed threshold may relate to an environment where the first device and the second device are located and a communication channel condition between the first device and the second device, which are not specifically described in the embodiments of the present invention.
Optionally, the differentiating the packet error rates included in the packet error rate set may refer to a first-order differentiating process or a second-order differentiating process, and in a specific implementation: dividing the target time into a plurality of time periods, such as t, dividing t into a plurality of equal-length time periods deltat 1 ,Δt 2 ,Δt 3 And the like, the specific division of the time periods into a plurality of time periods can be set according to actual needs, and the embodiment of the invention is not limited; calculating an average value of PER (or a filtered value similar to an averaging process) during each time period; if there are n adjacent time periods, the average of n PERs can be expressed as y 3 Δper { n }; for y 3 Second order differentiation processing is performed on Δper { n }, so that the packet error rate increase rate in the target time can be obtained.
In step S203, if the communication connection is about to be disconnected, a prompt message of the communication connection is about to be disconnected is output, and the prompt message carries a reason of the communication connection about to be disconnected.
It should be appreciated that in the event that a determination is made that the communication connection is about to be broken, a prompt carrying the reason for the impending break is output so that a relief solution is initiated based on the reason in the prompt to avoid the communication connection being broken. For example, the first device is a movable platform, and the second device is a control device, and if it is predicted that the communication connection between the first device and the second device is about to be disconnected in step S202, the first device may control the movable platform to perform a deceleration, ascent, hover, or original return operation according to a reason why the communication connection is about to be disconnected.
In an embodiment, the reason for the impending disconnection of the communication connection carried in the prompt message may be determined according to the second transmission quality parameter in step S201. Optionally, the second transmission quality parameter includes a reference signal received power, and the method further includes: and determining the reason that the communication connection is about to be disconnected according to the reference signal received power set in the target time.
In a specific implementation, the determining, according to the reference signal received power set in the target time, a reason that the communication connection is about to be disconnected includes: performing differential processing on a plurality of reference signal received powers included in the reference signal received power set to obtain a first change rate of the reference signal received power in the target time; comparing the first change rate with a theoretical value of the first change rate, and obtaining a first difference value between the first change rate and the theoretical value of the first change rate; and if the first change rate is smaller than the theoretical value of the first change rate and the first difference value is larger than a first difference value threshold, determining that the reason that the communication connection is about to be disconnected is that the communication link is blocked.
The theoretical value of the first change rate is calculated under the transmission link model condition that the communication link between the first device and the second device is assumed to be free space. The free space transmission link model refers to a wireless large space filled with uniform and linear isotropy ideal medium, and is an ideal condition. Propagation in free space is free of any attenuation and no blocking. In a specific implementation, an embodiment of the calculation of the theoretical value of the first rate of change may include: calculating the relative distance information between the first device and the second device in real Time by a global positioning system (Global Positioning System, GPS) or Round Trip Time (RTT); calculating the height information of the first equipment in real time through a GPS; acquiring the transmitting power of a signal transmitted by second equipment and the antenna receiving gain of first equipment; a theoretical value of the first rate of change in free space is calculated based on the above-mentioned relative distance information, altitude information, transmit power, and antenna reception gain of the first device. It should be noted that, the theoretical value of the first rate of change may also be calculated based on other transmission link models, and a person skilled in the art may select a corresponding transmission link model according to an actual application scenario, for example, a ground bijective propagation link model may also be used.
In one embodiment, the differentiating the plurality of reference signal received powers included in the reference signal received power set may refer to a first order differentiating. In a specific implementation, the implementation method for differentiating the plurality of reference signal received powers included in the reference signal received power set to obtain the first rate of change of the reference signal received power in the target time may include: dividing the target time into a plurality of time periods, such as t, dividing t into a plurality of equal-length time periods deltat 1 ,Δt 2 ,Δt 3 Etc., the value of each time period can be 10ms-1000ms; calculating an average value of RSRP (or a filtered value similar to an averaging process) over each time period; if there are n adjacent time periods, the average value of n RSRPs can be expressed as y 1 =Δrsrp { n }; for y 1 The first-order differential process is performed on Δrsrp { n }, so as to obtain a first rate of change in the target time.
Let pair y 1 The processing result of =Δrsrp { n } after the first-order differentiation processing, i.e., the first rate of change, can be expressed as y' 1 The theoretical value of the first rate of change is expressed as Y' 1 The first difference threshold is denoted as TL rsrp . Will y' 1 And Y' 1 Comparing, if y' 1 <Y′ 1 And |y '' 1 -Y′ 1 |>TL rsrp The reason for the impending disconnection of the communication connection may be determined to be occluded. Referring to fig. 3, a schematic diagram of a change of reference signal received power with time when being blocked is provided in an embodiment of the present invention, 301 in fig. 3 represents a schematic diagram of a change of reference signal received power theoretical in a target time, 302 represents a schematic diagram of a change of reference signal received power actually measured in the target time, and it can be seen in fig. 3 that in the target time t, a first change rate is smaller than a theoretical value of the first change rate.
In one embodiment, the first difference threshold may be determined by referring to attenuation coefficients of different materials, or may be obtained by training through different shielding materials in advance, for example, the types of common shielding may include any one or more of plants, concrete buildings, wooden buildings, metal buildings, human bodies, plastic objects and the like. Setting corresponding first difference thresholds for different types of shields, so that the first device judges the type of the shield which causes the communication connection to be disconnected according to the magnitude relation between the first difference and the first difference thresholds, for example, the first difference thresholds are set for a human body by referring to the shield, and when the first difference is smaller than the first difference thresholds, the first device and the second device indicate that the communication connection between the first device and the second device is affected by the shield, and the type of the shield is the human body. Therefore, when the reason why the communication link is about to be disconnected is that the communication link is blocked, the prompt message in step S103 may further include a type of the blocking object, where the type of the blocking object may include a human body, a plant, or a building, and the building may include any one or more of a concrete building, a wooden building, and a metal building.
In one embodiment, the step of determining the reason why the communication connection is about to be disconnected based on the second transmission quality parameter may be performed in synchronization with the step of predicting whether the communication connection between the first device and the second device is about to be disconnected based on the first transmission quality parameter, and outputting the reason why the communication connection is about to be disconnected if the communication connection is predicted to be disconnected.
In other embodiments, the step of determining the reason for the imminent disconnection of the communication connection based on the second transmission quality parameter may also be performed after predicting that the communication connection between the first device and the second device is imminent disconnection based on the first transmission quality; or, determining the reason that the communication connection is about to be disconnected may be performed before predicting whether the communication connection is about to be disconnected, and when the communication connection is predicted to be disconnected, the reason that the communication connection is about to be disconnected is carried in the prompt information to output.
The embodiment of the invention determines the first transmission quality parameter and the second transmission quality parameter by processing the signal received by the first equipment, and then predicts whether the communication connection between the first equipment and the second equipment is about to be disconnected according to the first transmission quality parameter; when the communication connection between the first device and the second device is predicted to be disconnected, outputting prompt information of the communication connection to be disconnected, wherein the prompt information can comprise the reason of the communication connection to be disconnected, and the reason of the communication connection to be disconnected is determined according to the second transmission quality parameter. The prompting information output by the embodiment of the invention can prompt that the communication connection is about to be disconnected and indicate the reason that the communication is about to be disconnected, thereby improving the operation safety of the first equipment or the second equipment.
Based on the above information processing method, the embodiment of the present invention further provides another information processing method, and referring to fig. 4, a flow chart of another information processing method provided by the embodiment of the present invention is shown.
The information processing method shown in fig. 4 is applied to a first device, a communication connection is established between the first device and a second device, and the first device and the second device can mutually transmit signals based on the communication connection. The information processing method described in fig. 4 may be executed by the first device, and in particular, may be executed by a processor of the first device. The information processing method shown in fig. 4 may include the steps of:
step S501, determining a first transmission quality parameter and a second transmission quality parameter according to a signal received by the first device.
In one embodiment, some possible implementations included in step S501 may refer to descriptions of related steps in the embodiment shown in fig. 2, which are not described herein.

In one embodiment, the first transmission quality parameter may include a carrier to interference plus noise ratio CINR, and predicting whether a communication connection between the first device and the second device is about to be broken based on the first transmission quality parameter comprises: predicting whether a communication connection between the first device and the second device is about to be disconnected according to a carrier-to-interference-and-noise ratio set in a target time.
As an optional embodiment, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of carrier-to-interference-and-noise ratios within the target time includes: acquiring a second number of carrier-to-interference-plus-noise ratios smaller than a ratio threshold among a plurality of carrier-to-interference-plus-noise ratios included in the carrier-to-interference-plus-noise ratio set; and if the second number is greater than or equal to a second number threshold, predicting that the communication connection between the first device and the second device is about to be disconnected.
The second number of thresholds may be determined based on a proportion of carrier to interference noise in the set of tolerable carrier to interference noise ratios that is less than the carrier to interference noise ratio threshold if the communication connection remains connected. Assuming that the proportion of the carrier-to-interference noise ratio in the carrier-to-interference noise threshold value in the preset carrier-to-interference noise ratio set is w%, the communication connection between the first device and the second device is predicted to be disconnected. The second number threshold may be determined according to the total number of carrier to interference plus noise ratios included in the carrier to interference plus noise ratio set and the proportion w% of carrier to interference plus noise ratios greater than the carrier to interference plus noise ratio, for example, w=60, and if the total number of all carrier to interference plus noise ratios included in the carrier to interference plus noise ratio set is 100, the second number threshold may be 60% ×100=60.
Alternatively, the carrier-to-interference-plus-noise ratio less than the carrier-to-interference-plus-noise ratio threshold may or may not be the carrier-to-interference-plus-noise ratio generated at consecutive times. For example, the carrier-to-interference-and-noise ratio set includes 5 carrier-to-interference-and-noise ratios, CINR1, CINR2, CINR3, CINR4, and CINR5 in order of time in which the carrier-to-interference-and-noise ratios are generated, and it is assumed that the second number of carrier-to-interference-and-noise ratios smaller than the carrier-to-interference-and-noise ratio threshold is 3, and the 3 carrier-to-interference-and-noise ratios may be consecutive times, such as CINR1, CINR2, CINR3; alternatively, the 3 carrier to interference plus noise ratios may not be consecutive times, such as CINR2, CINR4, and CINR5.
As another optional implementation manner, predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of carrier-to-interference-and-noise ratios in the target time includes: performing differential processing on a plurality of carrier-to-interference-plus-noise ratios included in the carrier-to-interference-plus-noise ratio set to obtain a carrier-to-interference-plus-noise ratio reduction speed in the target time; and if the carrier-to-interference-plus-noise ratio reduction speed is greater than or equal to a second speed threshold, predicting that the communication connection between the first device and the second device is about to be disconnected. The second speed threshold may be preset, and the second speed threshold may relate to an environment where the first device and the second device are located and a communication channel condition between the first device and the second device, which are not specifically described in the embodiments of the present invention.
