[0028] The following combination Figures 1-2 The embodiments shown illustrate the technical solution of this utility model:

[0029] This utility model provides a three-antenna wireless transmitter, including: a housing 1; an MCU main control board, which is fixedly installed inside the housing 1, and the MCU main control board adopts a low-latency anti-collision algorithm; a wireless serial port module, which is integrated on the MCU main control board, and the MCU main control board integrates three wireless serial port modules with different frequency bands; and a switch button 2, which is installed on the outer surface of the housing 1 and is electrically connected to the MCU main control board.

[0030] It is understood that this utility model provides a three-antenna wireless transmitter. By integrating a wireless serial port module with three frequency bands on the MCU main control board, it has strong anti-interference performance and improves the reliability of the transmitter in electromagnetic interference environment. The MCU main control board adopts a low-latency anti-collision algorithm, which greatly improves the accuracy of the two transmitters.

[0031] In this utility model, the outer shell 1 of the trigger is made of aluminum alloy, which is sturdy and drop-resistant. The shape of the outer shell 1 is rectangular, and the edges of the outer shell 1 are rounded. At the same time, the edges of the outer shell 1 are also thickened to ensure the stability of the outer shell 1. The overall structure of the trigger body is relatively flat. The body of the trigger is used to attach the instruction manual, which improves the practicality of the wireless trigger.

[0032] This utility model also includes an MCU main control board, which is fixedly installed inside the housing 1. The MCU main control board is the core component of the wireless trigger. The MCU main control board adopts a low-latency anti-collision algorithm, which is an existing algorithm. It is programmed on the MCU main control board to improve the accuracy of the timing device in receiving the trigger's instructions. The MCU main control board is installed inside the trigger to facilitate the protection of the MCU main control board.

[0033] This invention also includes a wireless serial port module, which is integrated on the MCU main control board. The wireless serial port module has three frequency bands. The transmission of the three wireless serial port modules is controlled by the low-latency anti-collision algorithm adopted by the MCU main control board, which greatly improves the accuracy and reliability of the timing device in receiving commands in the case of electromagnetic interference in the operating environment.

[0034] This utility model is provided with a switch button 2, which is located on the outer surface of the housing 1. The switch button 2 penetrates the housing 1 and is electrically connected to the MCU main control board. By operating the switch button 2, the starter can be controlled to perform timing.

[0035] According to the three-antenna wireless transmitter provided by this utility model: a battery compartment 3 is provided inside the outer shell 1, a battery is provided inside the battery compartment 3, and the battery compartment 3 is electrically connected to the MCU main control board.

[0036] In this invention, a battery compartment 3 is provided inside the outer casing 1. The embedded battery compartment 3 improves the aesthetics of the wireless transmitter. The battery compartment 3 is adjacent to the MCU main control board. A battery is removably housed within the battery compartment 3, and the shape of the battery compartment 3 matches the shape of the battery. This invention uses a 9V square battery, which has a large capacity, is readily available, and can be replaced when the battery is depleted. The battery compartment 3 is electrically connected to the MCU main control board, and the battery serves as the power source for the MCU main control board.

[0037] According to the three-antenna wireless transmitter provided by this utility model, the connection between the battery compartment 3 and the outer shell 1 can be opened.

[0038] In this invention, the connection between the battery compartment 3 and the outer shell 1 can be opened. The openable part is the cover of the battery compartment 3. After opening the cover of the battery compartment 3, the depleted battery can be removed, and after replacing it with a fully charged battery, the cover can be closed to replace the battery installed in the battery compartment 3. This ensures that the wireless transmitter can still be used continuously when the power is off. Since the wireless transmitter has a synchronous timing function, in order to avoid the wireless transmitter suddenly losing power during use, the battery can be replaced regularly, which improves the practicality of the wireless transmitter.

[0039] If the wireless transmitter is not needed for an extended period, open the battery compartment 3 cover, remove the built-in battery, and store it. This will reduce battery wear and extend the lifespan of the wireless transmitter.

[0040] According to the three-antenna wireless transmitter provided by this utility model: a protective cover 201 is provided on the surface of the switch button 2, and the protective cover 201 is rotatably connected to the surface of the outer shell 1.

[0041] In this utility model, a protective cover 201 is provided on the surface of the switch button 2 to prevent accidental contact with the switch button 2. The protective cover 201 is rotatably connected to the surface of the outer shell 1. The protective cover is made of transparent acrylic material. When the wireless transmitter is not in use, the protective cover 201 is fastened to the switch button 2 to prevent dust from entering the inside of the wireless transmitter through the gaps between the switch buttons 2 and causing unnecessary damage to the electronic components inside the outer shell 1. When using the wireless transmitter, simply rotate to open the protective cover 201 to operate the switch button 2.

[0042] According to the three-antenna wireless transmitter provided by this utility model: the MCU main control board integrates a short-press button module and a long-press button module. The short press of switch button 2 is used for timing, and the long press of switch button 2 is used to reset to zero.

[0043] In this invention, the MCU main control board integrates a short-press button module and a long-press button module. When the switch button 2 is pressed briefly, the switch button 2 sends a timing command. When the switch button 2 is pressed long, the switch button 2 sends a zeroing command. The operation is simple and reduces the difficulty of operating the wireless transmitter. It can work with just one button.

[0044] According to the three-antenna wireless transmitter provided by this utility model: the MCU main control board also integrates a power alarm module and a power off prompt module, and the surface of the housing 1 is embedded with a power alarm indicator light, which is electrically connected to the MCU main control board.

[0045] In this invention, the MCU main control board also integrates a power alarm module and a power-off prompt module. A power alarm indicator light is embedded on the surface of the housing 1, and the power alarm indicator light is electrically connected to the MCU main control board. When the battery power is critically low, the power alarm module sends an activation command to the power alarm indicator light; that is, when the power alarm indicator light is activated, it indicates that the battery power is low and needs to be replaced or charged.

[0046] The working principle of this utility model is as follows: Open the cover of the battery compartment 3, put the battery in the battery compartment 3, and then rotate the protective cover 201. If you need to time, press the switch button 2 briefly; if you need to reset to zero, press the switch button 2 for a long time. After use, close the protective cover 201. If the power alarm indicator light is on, it means that the battery power is low and you can replace the battery.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
