In this embodiment, the first hit area detector and the second hit area detector are the same device, the first slave controller and the second slave controller are the same device, the first slave fencing control button and the second slave fencing control button are the same device, and the first slave wireless communicator and the second slave wireless communicator are the same device. The following takes the first hit area detector, the first slave controller, the first slave fencing control button and the first slave wireless communicator as examples to describe the concrete implementation of each component.
In this embodiment, the fencing athlete connects to the first wireless communicator through a dedicated hand line for double-edged swords, the double-edged swords and the swords are international universal swords, the hand line is the international universal hand line, and the first hitting area detector determines the hitting area after hitting the fencing athlete of the opposite side through a signal transmitted back through the hand line after the sword body hits the opposite side. In this embodiment, the first in-collision region detector includes a first electromagnetic inductor and/or a first capacitive inductor, that is, the first in-collision region detector may be the first electromagnetic inductor or the first capacitive inductor, and in order to improve the detection accuracy, the first in-collision region detector may further include the first electromagnetic inductor and the first capacitive inductor at the same time. Wherein, first electromagnetic inductor is used for realizing the detection of hitting the region through the electromagnetic induction principle, specifically: according to the electromagnetic induction principle, when one fencing player hits a certain area of the other fencing player, the first slave controller receives a hitting signal, sends an electromagnetic detection signal to the sword point of the sword through a hand line, simultaneously detects the signal in real time through the first electromagnetic inductor, generates an eddy current effect after the sword point contacts a metal object, converts the magnetic field strength in a loop into analog voltage by the first slave controller, dynamically judges whether the sword point contacts the object according to the analog voltage value, judges whether the object in contact is metal or other objects according to the magnetic field strength when the sword point contacts the object, and can identify the size of the metal object according to the eddy current response of the metal if the object is metal so as to identify the hitting metal floor, the metal clothing worn with the person or the fencing hand protection disc of the sword. The first capacitive sensor realizes detection of a hit area by adopting a capacitive sensing principle, and specifically comprises: according to the capacitance change effect of a human body or other conductive objects or non-conductive objects when contacting the sword tip, the capacitance change value is converted into analog voltage and sent into the first slave controller, the first slave controller can accurately identify and judge the characteristics (skin or metal or non-metal) of the contact object according to the analog voltage value, and whether a hitting signal occurs or not is analyzed in real time according to fencing training rules.
Similarly, the second hit area detector includes a second electromagnetic sensor and/or a second capacitive sensor, and is configured to detect whether the hit object and the hit are valid.
The first slave controller and the master controller can be the same control chip, such as an MCU, a single chip microcomputer, etc.
The first slave fencing control button is used for controlling the starting and the shutdown of the first slave, and can also be used for selecting a slave prompting mode and selecting a fencing type.
The master wireless communicator is in wireless signal connection with the first slave wireless communicator and the second slave wireless communicator. The first slave wireless communicator and the second slave wireless communicator may be the same wireless communication device as the master wireless communicator, such as: the master wireless communicator is in 2.4G wireless communication with the first slave wireless communicator and the second slave wireless communicator.
It should be understood that the effective hit areas for different fencing categories are typically different, such as: the effective hitting areas corresponding to the double sword mode and the foil mode are different. Therefore, two kinds of data are set in the first slave controller and the second slave controller, one is a valid hitting area and an invalid hitting area corresponding to the double sword mode, and the other is a valid hitting area and an invalid hitting area corresponding to the foil mode. After one fencing type is selected through the main fencing type selection button, the main controller sends the fencing type to the two slave controllers, the slave controllers can determine corresponding effective hitting areas and invalid hitting areas according to the selected fencing type, and then whether the hitting area of the opposite fencing athlete hit is an effective hitting area or not is judged according to whether the hitting area detected by the hitting area detector is an effective hitting area, namely whether a hitting signal detected by the hitting area detector is an effective signal or an invalid signal is judged.
In this embodiment, the first slave further includes a first slave state prompt unit, and the first slave state prompt unit is in wired signal connection with the first slave controller. The first slave state prompting unit is used for prompting related states, such as fencing types and displaying whether the hitting signal is a valid signal or an invalid signal, and can be a conventional LED prompting screen. The second slave machine also comprises a second slave state prompting unit which is in wired signal connection with the second slave controller.
