[0057] Before further describing the embodiments of the present invention in detail, the nouns and terms involved in the embodiments of the present invention are described. The nouns and terms involved in the embodiments of the present invention are applicable to the following interpretations:

[0058] Contactless Radio Frequency Identification (RFID): is an automatic identification technology that uses radio waves to identify and track tags attached to objects. RFID technology allows data to be read without physical or visual contact.

[0059] Near Field Communication (NFC): is a short-range high-frequency radio technology that allows devices to perform wireless data transmission at close range. NFC technology is an integration of contactless radio frequency identification (RFID) and interconnection technology.

Devices using NFC technology can exchange data when they are close to each other.

[0060] Time-of-Flight (TOF) sensor: A distance measurement technology that determines the distance by emitting infrared light pulses and measuring the time from the emission to the reflection of these light pulses by the target object. The TOF sensor consists of an infrared transmitting tube and a receiving tube, where the transmitting tube is responsible for emitting light signals and the receiving tube captures the reflected light signals. Based on the speed of light and the flight time of the light pulse, the TOF sensor can accurately calculate the distance to the target object.

[0061] Gantry: In the context of drone racing, the word “gantry” is borrowed to describe a specific obstacle or goal that a drone needs to traverse.

[0062] In drone competitions, contestants can get a certain score by controlling the drone to cross the target obstacle along a preset path. The target obstacle can be a through hole with openings at both ends, or a through hole of a specific shape. In related technologies, manual recognition is mainly used to determine whether the drone has successfully crossed the target obstacle, and the contestants are scored accordingly. Scoring can be understood as recording the score. However, this scoring method is easily affected by human subjective judgment, making the scoring results inaccurate, thereby affecting the results of the competition.

[0063] Based on this, an embodiment of the utility model provides an automatic scoring circuit, which can realize automatic scoring and improve the accuracy of scoring.

[0064] Please refer to Figure 1 , Figure 1 It is a module schematic diagram of an automatic scoring circuit provided by an embodiment of the utility model. This automatic scoring circuit is used to score the process of a drone passing through a target obstacle. The target obstacle includes a target exit. The automatic scoring circuit is arranged on the inner surface of the target exit. The automatic scoring circuit includes a tag reading module 100, a laser ranging module 200 and a control module 300. Among them, the tag reading module 100 is used to collect the first tag information of the drone within a preset collection range; the laser ranging module 200 is used to emit a measuring laser, and when the drone runs to the target exit, the distance information between the laser ranging module and the drone is determined according to the measuring laser; the control module 300 is connected in communication with the tag reading module 100 and the laser ranging module 200, and the control module 300 is used to receive the first tag information and the distance information to determine the target score of the drone according to the first tag information and the distance information.

[0065] When the drone runs into the preset collection range, the tag reading module 100 will collect the first tag information of the drone; when the drone runs to the target exit, the laser ranging module 200 emits a measuring laser, and determines the distance information between the laser ranging module 200 and the drone according to the measuring laser; the control module 300 is connected to the tag reading module 100 and the laser ranging module 200 in communication, and the control module 300 is used to receive the first tag information and the distance information, so as to determine the target score of the drone according to the first tag information and the distance information. The automatic scoring circuit realizes automatic recording of the target score of the drone through the tag reading module 100, the laser ranging module 200 and the control module 300, which can avoid the situation of human scoring errors and improve the accuracy of scoring when the drone passes the target obstacle.

[0066] It should be noted that in drone competitions, in order to effectively distinguish between participating drones and their corresponding contestants, an NFC electronic tag is attached to a prominent position on the fuselage of each participating drone for quick identification during the competition. In addition, each NFC electronic tag has a unique ID number. This ID number can be used to distinguish different drones and ensure that each drone can correspond one-to-one with its designated contestant. Before the competition begins, the organizer will use an NFC reader to scan the NFC electronic tag on each drone, record the ID number of each NFC electronic tag, and associate it with the information of the corresponding contestant. The NFC electronic tag on the drone usually contains a microchip and an antenna. The microchip is used to store information, such as the drone's ID number or other identification data. The model of the NFC electronic tag is not specifically limited here. For example, the RFID high-frequency electronic tag 14443A can be used as the NFC electronic tag on the drone, and its operating frequency is 13.56MHz.

[0067] It should be noted that the tag reading module 100 can read the NFC electronic tag on the drone, the preset collection range can be the effective working distance of the tag reading module 100, and the first tag information can be the ID number of the NFC electronic tag on the drone. When the drone enters the preset collection range, the tag reading module 100 will emit high-frequency radio waves to activate the NFC electronic tag on the drone. After receiving the radio waves, the NFC electronic tag will send the information stored in its microchip (such as the ID number) back to the tag reading module 100 through its antenna.

[0068] Please refer to Figure 2 The automatic scoring circuit includes a tag reading module 100, a laser ranging module 200, a control module 300, a signal transmission module 400 and a power supply module 500. The signal transmission module 400 is electrically connected to the control module 300, and the signal transmission module 400 is used to generate a scoring signal according to the tag information and the distance information, and send the scoring signal to a preset terminal. The automatic scoring circuit also includes a power supply module 500, which is respectively connected to the tag reading module 100, the laser ranging module 200, the control module 300 and the signal transmission module 400, and the power supply module 500 is used to provide power to the tag reading module 100, the laser ranging module 200, the control module 300 and the signal transmission module 400.

[0069] It should be noted that the preset terminal can be a computer terminal, and the signal transmission module 400 generates a scoring signal according to the tag information and the distance information, and sends the scoring signal to the computer terminal, which performs the scoring operation and displays the target score; or, the control module 300 generates a scoring signal according to the tag information and the distance information to obtain the target score of the drone, and sends the scoring signal to the signal transmission module 400. The signal transmission module 400 transmits the scoring signal to the computer for scoring, and the computer terminal displays the target score.

[0070] Please refer to Figure 3 , Figure 3 It is a structural schematic diagram of a target obstacle provided by an embodiment of the utility model. The target obstacle is in the shape of an inverted cylinder, and two openings are respectively provided at both ends of the target obstacle to form a passage for crossing. The two openings correspond to each other in function, and are respectively called the target exit and the target entrance. In practical applications, the concepts of exit and entrance are relative, and there is no requirement to strictly distinguish or define them. During the competition, the contestant can control the drone to cross the target obstacle according to a preset path, that is, the drone needs to enter the target obstacle from the target entrance and then fly out from the target exit to successfully score. The target obstacle can be a gantry. The automatic scoring circuit is arranged on the inner surface of the target exit. When the drone enters the preset collection range, the tag reading module 100 can scan the NFC electronic tag of the drone to identify the ID number of the NFC electronic tag.

[0071] The laser ranging module 200 emits a measuring laser, which can be an infrared light pulse. When the infrared light pulse encounters the drone, part of the light will be reflected back. The laser ranging module 200 receives the infrared light pulse reflected from the drone, and calculates the distance between the automatic scoring circuit and the drone based on the total time from the emission to the reception of the light pulse (i.e., the flight time). When the drone does not fly to the target exit, the laser ranging module 200 emits a measuring laser and detects the distance as the diameter of the target obstacle (ignoring the volume of the automatic scoring circuit at this time). The laser ranging module 200 converts the detected distance information into an electrical signal, and then transmits it to the control module 300 to determine and score whether the drone has successfully crossed the target obstacle.

[0072] The control module 300 distinguishes the increase or decrease of the distance value by reading the numerical change of the electrical signal corresponding to the distance information. Assuming that the diameter of the target obstacle is 60 centimeters (cm), when the distance information satisfies a specific change pattern, that is, the distance value is initially stabilized at 60cm, then the value decreases, and finally returns to 60cm. This continuous change can be interpreted as the drone has successfully crossed the set target obstacle. Specifically, the initial stable stage of the distance value reflects that the drone has not entered the spatial range of the automatic scoring circuit (that is, the target exit); the subsequent distance reduction indicates that the drone begins to enter the spatial range of the automatic scoring circuit; finally, when the distance value returns to 60cm, this indicates that the drone has completely passed the target exit, that is, the drone has completely passed the target obstacle. At the same time, the control module 300 determines the target score of the drone through the received first tag information.

[0073] It should be noted that in the drone competition, if the drone loses control and falls into the obstacle due to an operational error while trying to cross the target obstacle, it is deemed that the crossing has not been successfully completed. In this case, although the drone is located inside the target obstacle, according to the competition rules, the drone does not meet the conditions for effectively passing the target obstacle, so it will not get the corresponding score. However, it is worth noting that even if the drone falls inside the obstacle, the tag reading module 100 may still be able to detect the NFC electronic tag attached to the drone and obtain the first tag information. At this time, the first tag information does not indicate that the drone has successfully crossed the obstacle, and the first tag information can only indicate that the drone is within the preset collection range. In order to avoid the possible misjudgment caused by relying solely on the tag reading module 100 detection, the present application also uses the laser ranging module 200 to emit infrared light pulses and measure the time required for these pulses to reflect back to accurately calculate the distance. If the drone falls during flight, the distance information received by the control module 300 at this time will not meet the aforementioned specific change mode, that is, the process of decreasing from the initial stable distance value and then increasing to the stable distance value again. Therefore, in order to ensure accurate judgment of whether the drone has successfully crossed the obstacle, the control module 300 must combine the first tag information of the tag reading module 100 and the distance information of the laser ranging module 200 to comprehensively judge whether the drone has successfully crossed the target obstacle. Only when the distance information indicates that the drone has crossed the target obstacle and the first tag information exists at the same time, can the drone be deemed to have completed an effective crossing, and thus automatically scored. This dual detection method improves the accuracy of automatic scoring and ensures the fairness of the competition.

[0080] Please refer to Figure 5 , Figure 5It is a circuit structure diagram of the laser ranging module provided by the embodiment of the utility model. The laser ranging module 200 includes a ranging unit 201 and a filtering unit 202. The ranging unit 201 includes a laser ranging chip, which is used to emit a measuring laser, and when the UAV runs to the target exit, the distance information between the laser ranging module 200 and the UAV is determined according to the measuring laser; it should be noted that the laser ranging chip can be a fourth chip U4. The filtering unit 202 is connected to the ranging unit 201, and the filtering unit 202 is used to filter out the voltage ripple input to the ranging unit 201. The laser ranging module 200 is connected to the control module 300 via the serial port I2C1.

[0081] In drone competitions, the tag reading module 100 can automatically collect the first tag information of the drone within a preset collection range, and the laser ranging module 200 measures the distance information between the drone and the drone when the drone passes through the target exit. When only one drone passes through the target obstacle at any time, the control module 300 can directly associate the received first tag information with the distance information to determine the target score of the drone. If the drone falls due to an operational error within the preset collection range, the control module 300 can clear the received first tag information if the control module 300 fails to receive the distance information that does not meet the aforementioned specific change pattern within a preset period of time after receiving the first tag information collected by the tag reading module 100.

[0082] It should be noted that when multiple drones pass through the target exit almost at the same time, the control module 300 can simultaneously receive multiple first tag information and multiple distance information. At this time, the control module 300 cannot directly correspond the received multiple first tag information and multiple distance information one by one according to the time relationship, thereby failing to ensure the accurate matching of the drone and the distance information, thereby affecting the scoring of the drone. Therefore, in other embodiments, the laser ranging module 200 may also include a tag measurement unit for collecting the second tag information of the drone when the drone runs to the target exit; wherein the control module 300 is also used to receive the second tag information and compare the first tag information with the second tag information to determine the target score of the drone based on the result of the information comparison and the distance information.

[0083] In one embodiment, the tag measurement unit may be an NFC reader. When the drone runs to the target exit, the drone is within the collection range of the tag measurement unit, and the second tag information may be the ID number corresponding to the NFC electronic tag of the drone. When multiple drones run to the target exit almost at the same time, the distance measurement unit 201 may determine the distance information between the laser ranging module 200 and each drone, and the tag measurement unit may scan the NFC electronic tag on each drone when the drone is within the collection range to obtain the second tag information. Because the first tag information is the ID number corresponding to the NFC electronic tag on the drone read by the tag reading module 100, the control module 300 may check whether the ID number corresponding to the first tag information and the ID number corresponding to the second tag information are consistent, and it can be determined which drone the multiple distance information belongs to. The control module 300 determines which drone the multiple distance information recorded by the laser ranging module 200 belongs to by comparing the ID numbers in the first tag information and the second tag information. This verification process ensures the accuracy of the scoring and avoids confusion caused by multiple drones passing through the target obstacle almost at the same time. Furthermore, after determining the corresponding drone, the control module 300 can associate the matching first tag information with the distance information to determine the target score of the drone.

[0084] In another embodiment, the tag measurement unit can also be a camera. In this way, when the drone runs to the target exit, the tag measurement unit can collect the image information of the drone, and the second tag information can be the image information of the drone. Before the game starts, the organizer will use a camera to collect images of each drone, record the image information of each drone, and associate it with the ID number of the corresponding NFC electronic tag of each drone. When multiple drones run to the target exit almost at the same time, the distance measurement unit 201 can determine its distance information with each drone, and the tag measurement unit can collect the second tag information of each drone. The control module 300 determines which drone the multiple distance information recorded by the laser ranging module 200 belongs to by comparing the ID number corresponding to the first tag information and the image information in the second tag information to ensure the accuracy of the scoring.

A capacitor with a large capacitance value usually has a large equivalent inductance, so its self-resonant frequency is small, so it is more suitable for filtering out low-frequency interference noise. A capacitor with a small capacitance value usually has a small equivalent inductance, so its self-resonant frequency is large, so it is suitable for filtering out high-frequency interference noise. In order to compensate for the deficiency of a capacitor with a large capacitance value under high frequency conditions, a capacitor with a small capacitance value is usually connected in parallel to provide a bypass for high-frequency interference signals, so that the filtering unit 202 can reduce the coupling interference of the outside world to the fourth chip U4.
