However, the reference voltage signal of the armor plate signal lights is 5V, while the microcontroller pin's default maximum output is only 3.3V, so this signal amplification circuit is designed to amplify the 3.3V voltage to 5V.

[0030] Furthermore, such as Figure 1 As shown, the microcontroller is an STM32F103C8T6.

[0033] Furthermore, such as Figure 3 As shown, the dart signal guide light circuit includes a resistor R21. One end of the resistor R21 is electrically connected to the microcontroller, and the other end of the resistor R21 is electrically connected to the gate of the MOSFET Q4. The source of the MOSFET Q4 is electrically connected to the ground terminal. A resistor R23 is placed between the gate and source of the MOSFET Q4.

[0034] Furthermore, the MOSFET Q4 is model AO3400A.

[0035] Furthermore, such as Figure 5As shown, the signal amplification circuit includes a signal amplification module U6. Pin 1 of the signal amplification module U6 is electrically connected to the +5V input terminal. Pin 19 of the signal amplification module U6 is electrically connected to the ground terminal. Pin 20 of the signal amplification module U6 is electrically connected to the +5V input terminal. One end of capacitor C25 and capacitor C26 connected in parallel is electrically connected to pin 20 of the signal amplification module U6, and the other end of capacitor C25 and capacitor C26 connected in parallel is electrically connected to the ground terminal.

[0036] Furthermore, the signal amplification module U6 is model number 74HC245D.

[0037] Furthermore, such as Figure 6 As shown, the signal amplification circuit is electrically connected to the signal light control circuit. The microcontroller controls the signal light control circuit through the signal amplification circuit, and then controls the armor plate signal light that is electrically connected to the signal light control circuit.

[0038] Furthermore, such as Figure 8 As shown, the base shield and health control circuit based on RS485 bus also includes a Type-C interface circuit, which is electrically connected to the microcontroller.

[0039] Furthermore, such as Figure 7 As shown, the base shield and health control circuit based on RS485 bus also includes an external Flash storage circuit, which is electrically connected to the microcontroller.

[0040] Furthermore, the storage control module U1 of the external Flash storage circuit is model W25Q32JVSIQTR.

[0041] Furthermore, such as Figure 4 As shown, the base shield and health control circuit based on RS485 bus also includes a power conversion circuit, which includes a power conversion module U3, model number XL1509-5.0E1.

[0042] The working process of the base shield and health control circuit based on RS485 bus is as follows:

[0043] The working process of this invention involves two core components: armor plate control and blood volume control, which achieve information transmission and linkage via an RS485 bus. The specific working process is as follows:

[0044] First, after the system starts up, the pressure sensors on the armor plate become active, ready to receive attacks from the player. Simultaneously, the STM32 control board for health control completes initialization, including configuring the RS485 communication module and the WS2811 LED strip driver module, ensuring the entire system is in standby mode.

[0045] When a player strikes the armor plate, a pressure sensor detects the impact force in real time and converts it into an electrical signal. After processing the signal, the sensor sends the impact data to the STM32 control board in the health control section via a built-in RS485 communication module. The use of the RS485 bus ensures the stability and anti-interference capability of the data during transmission.

[0046] After receiving the impact data, the STM32 control board calculates the reduction in blood loss based on a preset algorithm. Then, the control board sends control commands to the WS2811 LED strip via the SPI protocol. The LED strip displays the corresponding color and brightness based on the blood loss reduction value, visually reflecting the degree of damage to the armor plate.

[0047] Throughout the game, the armor plates and health control system maintain constant communication. Whenever the armor plates are hit, the impact data is transmitted to the STM32 control board in real time, and the control board updates the LED display accordingly to ensure that the player receives immediate health feedback.

[0048] In addition, the STM32 control board also has a monitoring function, which monitors the RS485 communication status and the LED strip display in real time. Once an anomaly is detected, such as a communication interruption or LED strip failure, the control board will immediately take corresponding measures, such as re-establishing the communication connection or switching to a backup LED strip, to ensure the smooth running of the game.

[0049] When the game ends, the armor plate sends an end signal to the STM32 control board. Upon receiving the signal, the control board turns off the WS2811 LED strip and restores it to its initial state, preparing for the next game. Simultaneously, the control board stores the game data for analysis, providing a basis for device optimization.

[0050] In summary, this invention tightly connects the armor plates and the health control unit via RS485 bus, achieving an efficient and stable gaming experience. This allows players to intuitively understand the damage status of the armor plates during interaction, enhancing the game's fun and realism.

[0051] In summary, the base shield and health control circuit based on the RS485 bus provided in this embodiment, which collects armor plate impact information through the RS485 bus to achieve real-time monitoring and linkage control of the base's health, has the following advantages: Stable data transmission: The bus is a stable communication protocol that can achieve long-distance data transmission and is suitable for bridging various complex circuit systems; Strong real-time performance: The bus can achieve real-time data transmission, making the system react faster and more suitable for application scenarios requiring rapid response; High reliability: The bus has high anti-interference capability and fault tolerance, which can ensure the stable operation of the system in complex environments; Easy maintenance: The circuit system based on the RS485 bus has a high degree of modularity, is easy to diagnose and repair, and reduces the maintenance cost and difficulty of the system.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
