The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The features of the following examples and embodiments may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a method of identifying an attack on a first mobile platform according to an embodiment of the present invention. As shown in fig. 1, on the first mobile platform side, the attack identification method may include the steps of:
s101: after transmitting the current attack and the identity information of the first movable platform to the target movable platform, receiving broadcast information sent by the second movable platform, wherein the broadcast information carries the identity information of an attack transmitting end hitting the second movable platform;
it should be noted that the second movable platform may be the target movable platform, and may also include the target movable platform and other movable platforms (not the first movable platform).
In this embodiment, the first movable platform transmits the current attack and the identity information thereof in the same time period, and optionally, in some embodiments, the first movable platform transmits the current attack and transmits the identity information of the first movable platform in a synchronous manner, so as to implement one attack. That is, the first movable platform transmits the current attack and the identity information thereof to the target movable platform at the same time, so as to realize one attack on the target movable platform.
In some embodiments, the first movable platform transmits the current attack and transmits the identity information of the first movable platform in a sequential manner to implement a one-time attack. In this embodiment, the first movable platform may transmit the current attack first, and then transmit the identity information of the first movable platform; the first movable platform can also transmit the identity information of the first movable platform before transmitting the current attack. In this embodiment, when the first movable platform implements an attack, a time interval between transmitting the current attack and the identity information of the first movable platform is less than or equal to a second preset time duration. The second preset duration may be set as needed, for example, the second preset duration may be set to 1ms, 2ms, 3ms, 4ms, or 5 ms.
The attack mode can include, but is not limited to, a projectile attack, an optical signal attack, and the like, and the identity information is a wireless signal, such as an optical signal or other types of wireless signals. As a feasible implementation manner, the current attack is a shot attack, and the identity information is an optical signal. Wherein the first movable platform may attack the target movable platform by shooting a water projectile or other type of projectile; the first movable platform can emit one or more shots when carrying out one-time attack; the identity information can be an infrared light signal, a laser signal or other types of light signals; when the first movable platform attacks once, the duration of the emitted infrared light signal is preset duration.
As another possible implementation, the current attack is an optical signal attack, and the identity information is an optical signal. Optionally, the current attack and identity information are different types of optical signals, for example, the first movable platform attacks the target movable platform based on laser, and then transmits an infrared light signal carrying the identity information to the target movable platform, that is, the current attack is a laser signal, and the identity information is an infrared light signal; optionally, the current attack and the identity information are optical signals of the same type, and the content of the optical signal corresponding to the current attack is different from the content of the optical signal corresponding to the identity information. When the first movable platform attacks once, the duration of the optical signal attack signal and the duration of the identity information are both preset durations, and the two durations can be equal or unequal.
It should be noted that, in the embodiment of the present invention, the identity information is a non-broadcast signal, because if the first movable platform transmits its own identity information in a broadcast manner, the accuracy of attack identification is low. For example, the movable platform a launches a water bomb and informs all the movable platforms in a broadcasting manner that the first movable platform a launches the water bomb and identity information of the first movable platform a at the time T1; then, at the time T2, the second movable platform B is attacked, and it needs to be determined whether the attack on the second movable platform B at the time T2 is from the water bomb launched by the first movable platform a at the time T1, and a relatively accurate way is to determine the relative distance between the first movable platform a and the second movable platform B and the speed of launching the water bomb by the first movable platform a; if the attack on the second movable platform B at the time T2 comes from the water bomb launched by the first movable platform A at the time T1, calculating the time difference between the time when the first movable platform A launches the water bomb and the time when the second movable platform B detects the water bomb (T2-T1-the communication delay time between the first movable platform A and the second movable platform B), wherein the communication delay time between the first movable platform A and the second movable platform B is shorter and can be ignored; if the identity information is transmitted based on a broadcasting mode, the relative distance between the first movable platform A and the second movable platform B cannot be determined, so that attack matching is inaccurate; and the relative distance between the first movable platform A and the second movable platform B can be determined based on the identity information transmitted in a non-broadcast mode, such as an optical signal mode, so that the accuracy of attack matching is ensured.
Referring to fig. 2, the first movable platform may include a first optical signal emitting mechanism 120, the first optical signal emitting mechanism 120 for emitting identity information. Wherein, the angle range of the emitted light signal of the first light signal emitting mechanism 120 is less than or equal to the first preset angle, and with the first light signal emitting mechanism 120 with a narrow angle (i.e. the angle range is less than or equal to the first preset angle), the identity information emitted by the first movable platform is as close as possible to the attack range of the current attack emitted by the first movable platform, so that the target movable platform can be matched with the attack source accurately, and the identity information emitted by the first movable platform can be better oriented to the target movable platform. Correspondingly, the second movable platform may include a first optical signal receiving mechanism, the second optical signal receiving mechanism is configured to detect the optical signal carrying the identity information of the first movable platform and transmitted by the first optical signal transmitting mechanism 120, and the second optical signal receiving mechanism may be disposed on the body and/or the cradle head of the first movable platform. Optionally, the first optical signal emitting mechanism 120 is an infrared emitting sensor, and the first optical signal receiving mechanism is an infrared receiving sensor; optionally, the first optical signal transmitting mechanism 120 is a laser transmitting sensor, and the first optical signal receiving mechanism is a laser receiving sensor. The first preset angle may be 1 °, 2 °, 3 °, or the like.
In addition, the identity information of this embodiment may be an ID, or may be other identification information for characterizing the identity of the first movable platform.
Furthermore, the identity information of each movable platform needs to be ensured to be unique, and the identity positioning of the attack transmitting terminal is realized.
In some embodiments, as shown in fig. 2, a plurality of movable platforms of the competitive game are networked based on a local area network, and the networking based on the local area network can ensure that the identity information of each movable platform is unique. The mobile platforms realize networking based on a wireless local area network mode such as wifi, Bluetooth or other wireless modes. For the broadcast information of this embodiment, the second movable platform sends the broadcast information based on the local area network, which may be specifically referred to the description in the second embodiment below. In the embodiment, the identity information of each movable platform is unique through the local area network, and the attacked parameter information and the identity information of the attack transmitting terminal hitting the second movable platform are broadcasted through the local area network, so that the attack transmitting terminal can judge whether the attack transmitting terminal hits or not, and the implementation process is simple.
In some embodiments, the first movable platform is provided with a second optical signal receiving mechanism, the second movable platform is provided with a second optical signal emitting mechanism, and the angle range of the light signal emitted by the second optical signal emitting mechanism is greater than or equal to a second preset angle. The broadcast information of this embodiment is broadcast by the second movable platform based on the second optical signal transmitting mechanism, and is detected by the second optical signal receiving mechanism. The second optical signal transmitting mechanism with a wide angle (namely, the angle range is greater than or equal to a second preset angle) is used, so that the second movable platform can transmit signals in a large range, and the purposes of broadcasting parameter information of attacks (attacks received by the second movable platform) and hitting identity information of an attack transmitting end of the second movable platform under the condition of no networking are achieved. Optionally, the second preset angle is 360 °, so that the second movable platform also has a function of transmitting broadcast information in all directions without networking. As a feasible implementation mode, the two sides of the machine body of the second movable platform are respectively provided with a second optical signal receiving mechanism with a wide angle, so that the second movable platform can realize the omnibearing broadcast information transmission. Further, the attack identification method may further include the steps of:
(1) when the first movable platform is powered on, allocating identity information to the first movable platform;
in this step, the first movable platform assigns a random identity information to itself when it is powered on and started.
(2) When the current identity information is received, if the identity information of the first movable platform which is currently distributed is the same as the current identity information and the first movable platform does not transmit the identity information of the first movable platform within a third preset time length before the moment of receiving the current identity information, distributing a new identity information for the first movable platform.
The method is suitable for a method that the first movable platform transmits the identity information of the first movable platform based on the optical signal when one attack is realized, and if the first movable platform transmits the optical signal to an obstacle due to the reflection condition of the optical signal, the optical signal transmitted by the first movable platform can be received due to reflection. Therefore, if the current identity information received by the first movable platform is the same as the currently allocated identity information, it is further determined that the first movable platform itself does not transmit the identity information within a third preset time period (e.g., 50ms) before the time when the current identity information is received, and if the first movable platform itself does not transmit the identity information within the third preset time period before the time when the current identity information is received, it indicates that the identity information of other movable platforms and the identity information of the first movable platform conflict with each other.
Through the steps (1) and (2), the uniqueness of the identity information of the plurality of movable platforms is realized under the condition that a local area network is not established.
S102: and matching the identity information of the first movable platform with the identity information of the attack transmitting terminal in the broadcast information to determine the attack result of the current attack.
In this embodiment, if the identity information of the first movable platform is the same as the identity information of the attack transmitting end in the broadcast information, it is determined that the attack result of the current attack is successful.
The broadcast information is received by the first movable platform within a first preset time after the current attack to the target movable platform is transmitted. In this embodiment, if the first movable platform does not receive the broadcast information within a first preset time after transmitting the current attack to the target movable platform, it is determined that the attack result of the current attack is a failure. The first preset time period can be set as required, and the first preset time period can be 50ms or other.
It can be understood that, since there may be a mutual attack between multiple movable platforms in the same time period, the first movable platform may receive multiple broadcast messages within a first preset time period after transmitting the current attack to the target movable platform.
As shown in fig. 3, when the first movable platform receives a plurality of broadcast messages within a first preset time after transmitting the current attack to the target movable platform, the implementation process of step S102 specifically includes: and according to the time sequence of the first movable platform for receiving the plurality of broadcast messages, sequentially matching the identity information of the first movable platform with the identity information of the attack transmitting terminal in the plurality of broadcast messages, and determining the attack result of the current attack. In this embodiment, if the identity information of the first movable platform is the same as the identity information of the attack transmitting terminal in any broadcast information, it is determined that the attack result of the current attack is successful; and if the identity information of the first movable platform is different from the identity information of the attack transmitting end of each piece of broadcast information in the plurality of pieces of broadcast information, judging that the attack result of the current attack is failure.
In some embodiments, determining the attack result of the current attack specifically includes: and outputting the attack result of the current attack, so that the user is prompted after the target is hit. The attack result of the current attack may be output based on any form of sound, text, light, or a combination thereof.
In addition, in some embodiments, the broadcast information also carries parameter information of an attack hitting the second movable platform. The parameter information may include, but is not limited to, at least one of: strength, orientation information and action position. Wherein, the intensity of force can include the intensity of force that the fuselage of second movable platform and/or cloud platform received the attack. The orientation information may include a direction of a source of an attack on the second movable platform, or a direction of a force of the attack on the second movable platform, or a position of the attack indicating the acting position of the attack. The active position may comprise a specific position on the body of the second movable platform upon which the attack is made and/or a specific position on the head upon which the attack is made.
Corresponding to the attack identification method in the foregoing embodiment, an embodiment of the present invention further provides a movable platform, where the movable platform in this embodiment is a first movable platform, and referring to fig. 4, the first movable platform may include a storage device and a processor.
Wherein the storage device is used for storing program instructions;
one or more processors, which call the program instructions stored in the storage device, and when the program instructions are executed, the one or more processors are individually or collectively configured to receive broadcast information sent by a second movable platform after transmitting a current attack and identity information of the first movable platform to a target movable platform, wherein the broadcast information carries identity information of an attack transmitting end hitting the second movable platform; matching the identity information of the first movable platform with the identity information of an attack transmitting terminal in the broadcast information to determine the attack result of the current attack; wherein the second movable platform comprises other movable platforms in the athletic competition except the first movable platform.
The processor may implement the attack recognition method according to the embodiment shown in fig. 1 and fig. 3, and the movable platform of this embodiment will be described with reference to the attack recognition method according to the above embodiment.
Example two
Fig. 5 is a flowchart of a method of attack recognition on the second mobile platform side in an embodiment of the invention. As shown in fig. 5, on the second movable platform side, the attack identification method may include the steps of:
s501: detecting that the second movable platform is attacked, and acquiring parameter information of the attack;
the attack detection mode is determined according to a specific attack mode, for example, in some embodiments, the attack mode is a contact attack, such as a shot attack, and armors are arranged on the body and/or the holder of the second movable platform and can sense external attacks. Armor may be disposed at one or more positions of the second movable platform according to actual requirements, for example, the armor may be disposed at the left side, the right side, the front side, the right side of the body of the second movable platform and/or other positions of the body, and the armor may also be disposed at the left side, the right side of the pan-tilt and/or other positions of the pan-tilt.
In some embodiments, the attack mode is a contactless attack, such as a light emission attack. Optionally, an infrared receiver is arranged on the body or the cradle head of the second movable platform, and the infrared receiver can be mounted on an outer frame of the body, so that infrared light sent by the first movable platform can be conveniently detected, and external attacks can be sensed. The infrared receiver can receive infrared light sent by the first mobile platform at 360 degrees and detect omnibearing attacks.
In this step, the parameter information includes at least one of: strength, orientation information and action position. Wherein, the intensity of force can include the intensity of force that the fuselage of second movable platform and/or cloud platform received the attack. The orientation information may include a direction of a source of an attack on the second movable platform, or a direction of a force of the attack on the second movable platform, or a position of the attack indicating the acting position of the attack. The active position may comprise a specific position on the body of the second movable platform upon which the attack is made and/or a specific position on the head upon which the attack is made.

Optionally, in some embodiments, the second movable platform detects the attack and the identity information synchronously, and transmits the current attack and transmits the identity information of the first movable platform according to the synchronous manner corresponding to the first movable platform, so as to implement a case of one attack.
In some embodiments, the second movable platform detects the attack and the identity information based on the sequence, and transmits the current attack and transmits the identity information of the first movable platform corresponding to the first movable platform in a sequential manner, so as to implement the situation of one attack. Correspondingly, the second movable platform detects the attack firstly and then detects the identity information; the second movable platform may also detect the identity information first and then detect the attack. In this embodiment, the time interval between the attack detection and the identity information detection of the second movable platform is less than or equal to a fourth preset time. In this manner, the second movable platform can be considered to detect attacks and identity information approximately simultaneously. The size of the fourth preset time period can be set as required, for example, the fourth preset time period can be set to 1ms, 2ms, 3ms, 4ms or 5 ms. Optionally, the fourth preset duration is equal to the second preset duration.
S503: and sending broadcast information to trigger the transmitting terminal to determine an attack result of the attack according to the broadcast information, wherein the broadcast information carries attack parameter information and identity information of the first movable platform.
The process of determining the attack result of the attack according to the broadcast information by the transmitting end is similar to the implementation process of step S102 in the first embodiment, and is not described here again.
As shown in fig. 6, the process of the second movable platform transmitting the broadcast information may include the steps of:
s603: adding the parameter information of the attack and the identity information of the first movable platform into the same broadcast information;
the parameter information of the attack and the identity information of the first movable platform can be added into different fields of the same broadcast information, and the parameter information of the attack and the identity information of the first movable platform can be distinguished conveniently.
S602: broadcast information is broadcast.
The manner in which the second movable platform broadcasts the broadcast information may include, but is not limited to, the following two:
first, as shown in fig. 2, a plurality of movable platforms of an athletic competition are networked based on a local area network, and identity information of each movable platform is unique; the broadcast information is sent over a local area network for the second movable platform.
