Detailed implementation manners
[0062] The following will clearly and completely describe the concept of the present invention and the technical effects produced in combination with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. If a certain feature is referred to as "set", "fixed", "connected", "installed" on another feature, it can be directly set, fixed, connected, or installed on another feature, or indirectly set, fixed, connected, or installed on another feature.

If it involves "first", "second", it should be understood as used to distinguish technical features, rather than indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0065] Currently, it is necessary to monitor and feedback on highway vehicles. Therefore, a professional monitoring and feedback system has emerged to guide road traffic conditions, and beacon devices are set up in traffic guidance to indicate road conditions. Since multiple beacon devices need to be set up on highways, in order to ensure the normal communication of the beacon devices, a wireless transmission control module is set up to receive remote control instructions and remotely send the detection information at that location to the background for monitoring. However, the current wireless transmission control module and beacon devices need to be started for a long time so that the wireless transmission control module can always receive remote control instructions and then send them to the beacon devices for control, so as to prompt the drivers through the beacon devices and improve traffic safety.
[0066] For this reason, the present application discloses a beacon control system. By separately starting the wireless transmission control module and the main control module, after the wireless transmission control module completes the transmission of the control instruction, it enters the sleep state to reduce the power consumption of the wireless transmission control module, thereby achieving the low-power effect of beacon control.
[0067] Refer to Figure 1, embodiments of the present invention disclose a beacon control system, including: a main control module 100, a power supply module 200, and a wireless transmission control module 300. The power supply module 200 is used to supply electrical energy to the main control module 100. The wireless transmission control module 300 is used to output a first control signal to cut off the power supply of the main control module 100 in the powered-on state. The wireless transmission control module 300 is further used to output a second control signal to close the power supply of the main control module 100 and enter the sleep state after completing network access.
[0068] Among them, a fixed processing chip is provided inside the wireless transmission control module 300, and the wireless transmission control module 300 automatically processes the network access procedure. The main work of the wireless transmission control module 300 is to perform network access, data packing, disassembly, and data sending and receiving. Among them, network access is equivalent to establishing a network connection, and after completing the network connection, it connects to the remote background through the network. The wireless transmission control module 300 packing data is equivalent to receiving the data sent by the main control module 100, packing it, and then sending it to the remote background. Disassembly is equivalent to the wireless transmission control module 300 disassembling the data packet sent by the remote background, and the disassembled data is sent to the main control module 100. After the wireless transmission control module 300 is powered on, it performs data processing. Since the main control module 100 does not need to receive and send data during the data processing of the wireless transmission control module 300, the wireless transmission control module 300 controls the main control module 100 to turn off. When the wireless transmission control module 300 completes data processing, the main control module 100 is started to control the main control module 100 to send or receive data. Moreover, after the main control module 100 receives or sends data, the wireless transmission control module 300 enters the sleep mode. Since generally the wireless transmission control module 300 needs to be started for a long time, but the wireless transmission control module 300 monitors the background and data sending and receiving for a long time, which consumes a large amount of electrical energy. By turning off the main control module 100 when the wireless transmission control module 300 is performing data processing and entering the sleep state after the wireless transmission control module 300 completes data processing, and then starting the main control module 100, therefore, by starting the wireless transmission control module 300 and the main control module 100 separately, electrical energy can be saved, and low power consumption of the entire beacon control system can be achieved.
[0069] In some embodiments, the wireless transmission control module 300 is electrically connected to a timing module. The timing module is used to preset a timing time and send a timing signal to the wireless transmission control module 300. The wireless transmission control module 300 starts according to the timing signal to receive data.
[0070] Among them, the timing module sends a timing signal to the wireless transmission control module 300 at a preset timing time. After receiving the timing signal, the wireless transmission control module 300 is activated to receive data sent from the main control module 100 or the remote background at regular intervals, thereby completing the data reception. When the wireless transmission control module 300 enters the sleep state when data reception is completed or there is no data reception, and is activated regularly to receive data. By setting the timing module, both data reception can be maintained and power can be saved.
[0071] In some embodiments, the beacon control system further includes: an indication module 400. The wireless transmission control module 300 is further configured to receive a control instruction and send the control instruction to the main control module 100; the main control module 100 receives and analyzes the control instruction and outputs a first main control signal. The indication module 400 is configured to receive the first main control signal and output an indication signal.
[0072] Since the main control module 100 sends traffic data about traffic information to the remote background through the wireless transmission control module 300, the remote background forms a corresponding control instruction according to the traffic data, and the remote background sends the control instruction to the main control module 100 through the wireless transmission control module 300. The main control module 100 analyzes the control instruction to generate a first main control signal for controlling the start or stop of the indication module 400. By controlling the indication module 400 to output a corresponding indication signal to prompt the driver of the current traffic situation, so that the driver can master the current traffic situation, improve traffic safety, and reduce traffic accidents.
[0073] In some embodiments, the beacon control system further includes: a detection module 500. The detection module 500 is configured to detect the traffic situation to form a detection signal. The main control module 100 is further configured to output a third main control signal to control the start or stop of the detection module 500.
[0074] Specifically, the main control module 100 outputs a third main control signal to the detection module 500 according to the control instruction to control the detection module 500 to start. Then the detection module 500 detects the traffic situation and outputs a detection signal to the main control module 100. By controlling the main control module 100 to start or stop the detection module 500, it is convenient to start or stop the detection module 500 according to actual needs, without the detection module 500 starting all the time, reducing the power consumption of the detection module 500, thereby realizing the low power consumption of the system.
[0075] Refer to together Figure 1 and Figure 2In some embodiments, the power module 200 includes: an external charging unit 210, a solar energy conversion unit 220, an energy storage unit 230 and a power control unit 240; the external charging module is used to receive the first electric energy of external charging; the solar energy conversion unit 220 is used to convert solar energy into the second electric energy; the energy storage unit 230 is used to store the first electric energy and the second electric energy to output electric energy; the power control unit 240 is used to receive the first main control signal and the third control signal to control the power supply of the indication module 400; the second power control unit 240 is also used to receive the third main control signal to control the power supply of the detection module 500.
[0076] Among them, multiple power control units 240 are set, and the main control module 100 controls the startup or shutdown of the detection module 500 through the power control unit 240, and the main control module 100 is connected to the power control unit 240 through SPI_POWER_EN management and RM_POWER_EN management, so that the operation of controlling the startup or shutdown of the power control unit 240 is simple.
[0077] Among them, the external charging unit 210 is USB charging, and the USB charging is input to the energy storage unit 230 with a voltage of 4.2V. The solar energy conversion unit 220 is two solar panels with a power of 0.65W, which convert solar energy into the second electric energy through the solar panels, and the solar panels output a voltage of 5.5V to the energy storage unit 230. In this embodiment, the energy storage unit 230 is a military-grade 18650 wide-temperature lithium-ion battery, and the capacity of the lithium-ion battery is 5200mAh. After storing energy through the lithium-ion battery, the electric energy is output to the main control module 100, the indication module 400, the detection module 500 and the wireless transmission control module 300 to provide electric energy to the main control module 100, the indication module 400, the detection module 500 and the wireless transmission control module 300, so that the main control module 100, the indication module 400, the detection module 500 and the wireless transmission control module 300 are started normally.
[0078] The circuit connection structure of the external charging unit 210 is specifically referred to Figure 3 , and the external charging unit 210 includes a charging chip U7, and the model of the charging chip U7 is EMC5754. The power input from the USB interface is converted into a first electrical energy of 4.2V through the charging chip U7, and sent to the energy storage unit 230 for storage.
[0079] The circuit connection structure of the solar energy conversion unit 220 is specifically referred to Figure 4 Two solar panels are provided, and a diode is connected to the output end of each solar panel, and rectification is performed by the diode to isolate the reverse current, so that the electric energy input to the energy storage unit 230 is stable.
[0080] Output the first electric energy to the lithium-ion battery through USB charging, and then convert solar energy into the second electric energy through the solar panel and store it in the lithium-ion battery. The lithium-ion battery stores the first and second electric energies and then outputs electric energy to the main control module 100, the indication module 400, the detection module 500, and the wireless transmission control module 300 to enable the normal startup of the main control module 100, the indication module 400, the detection module 500, and the wireless transmission control module 300.
[0081] In some embodiments, the power supply module 200 further includes: a conversion unit 250, which is used to convert electric energy into an output voltage matching the main control module 100, the indication module 400, and the detection module 500. Therefore, through the conversion unit 250, the voltage stored in the energy storage unit 230 can be converted into an output voltage matching the main control module 100, the indication module 400, the detection module 500, and the wireless transmission control module 300.
[0082] Since the energy storage unit 230 generally outputs a voltage of 4.2V, and the conversion unit 250 is a DC-DC conversion chip, the 4.2V voltage is converted into an output voltage of 3.3V through the DC-DC conversion chip to meet the voltage startup requirements of the main control module 100, the indication module 400, the detection module 500, and the wireless transmission control module 300.
[0083] Among them, the circuit connection structure of the conversion unit 250 specifically refers to Figure 5 , and the model of the DC-DC conversion chip U8 is TPS6274XD. The DC-DC conversion chip U8 is connected with an output capacitor, and the output capacitor satisfies low output ripple, thereby realizing the requirement of low noise in power output, so as to be applicable to occasions with high requirements for output voltage ripple. When the voltage of the energy storage unit 230 is close to the output voltage, the DC-DC conversion chip U8 outputs in a 100% ripple-free mode. At the same time, the DC-DC conversion chip U8 supplies power to other modules according to the main control signal output by the main control module 100. Therefore, the main control module 100 controls whether the DC-DC conversion chip U8 outputs or not, and can control the startup or shutdown of other modules, making the on-off control of other modules simple. The main control module 100 is connected to the DC-DC conversion chip U8 through the wireless transmission control module 300, and the wireless transmission control module 300 controls whether the DC-DC conversion chip U8 outputs electric energy to the main control module 100 to control the startup or shutdown of the main control module 100, making the on-off control of the main control module 100 simple.
[0084] In some embodiments, the power supply module 200 is electrically connected with a total switch module 600, and the total switch module 600 is used to control the startup or shutdown of the power supply module 200, and controls whether the power supply module 200 outputs electric energy to realize the power-on and power-off operations of the entire system.
[0085] Among them, the main switch module 600 is mainly composed of a ball switch J10, an eighteenth MOS transistor Q18, and a nineteenth MOS transistor Q19. The circuit connection structure of the ball switch J10, the eighteenth MOS transistor Q18, and the nineteenth MOS transistor Q19 specifically refers to Figure 6 . When the ball switch J10 is disconnected, the gate of the nineteenth MOS transistor Q18 outputs a high level, and the drain outputs a low level, then the nineteenth MOS transistor Q19 is started, and the eighteenth MOS transistor Q18 is started, and then the entire power supply module 200 starts to output electric energy to each module. If the ball switch J10 is conducting, the nineteenth MOS transistor Q19 is turned off, and the eighteenth MOS transistor Q18 is also turned off to control the power supply module 200 not to output electric energy externally, so as to achieve the purpose of powering off the entire system. Therefore, by setting the control of the ball switch J10, the eighteenth MOS transistor Q18, and the nineteenth MOS transistor Q19, the startup and shutdown operations of the entire system are simple, so as to cut off the power supply in case of an emergency.
[0086] In some embodiments, the wireless transmission control module 300 can be any one of a LORA module, a WIFI module, a Bluetooth module, and a GPRS module. In this embodiment, the wireless transmission control module 300 is a LORA module, and the specific circuit connection structure of the LORA module refers to Figure 7 , and the LORA module is composed of a LORA chip U5. The model of the LORA chip U5 is TPS6274XD, and the LORA chip is connected to the DC-DC conversion chip through the CPU_POWER_ON / OFF pin, and is connected to the main control module 100 through the LPUART1_TX and LPUART1_RX pins. When the wireless transmission control module 300 is in the powered-on state, the CPU_POWER_ON / OFF pin of the LORA chip U5 outputs a low level, and the CPU_POWER_ON / OFF pin of the LORA chip U5 is connected to the conversion unit 250 to output a low level to the DC-DC conversion chip U8 to cut off the DC-DC conversion chip U8 and the main control module 100, thereby cutting off the power supply of the main control module 100. If the wireless transmission control module 300 completes network access and receives a system power-on command, the CPU_POWER_ON / OFF pin of the LORA chip U5 outputs a high level, then the connection between the DC-DC conversion chip U8 and the main control module 100 is turned on, thereby realizing the normal startup of the main control module 100. Then, after the wireless transmission control module 300 and the main control module 100 complete data transmission, they enter the sleep state to save the electric energy of the wireless transmission control module 300.
[0087] In some embodiments, the main control module 100 includes: a data transceiver unit 110 and a parsing unit 120. The data transceiver unit 110 is configured to receive detection data and send the detection data to the wireless transmission control module 300. The parsing unit 120 is configured to receive a control instruction and parse the control instruction to output a first main control signal, a second main control signal, and a third main control signal.
[0088] Since the main control module 100 does not need to participate in the data processing of the wireless transmission control module 300, the main control module 100 only needs to report the status of the main control chip and the processed detection signal, and parse the control instructions sent by the wireless transmission control module 300. During other times, it enters the sleep and standby states, thereby reducing power consumption. Data reception and transmission are performed through the data transceiver unit 110, and the parsing unit 120 parses the control instructions sent by the wireless transmission control module 300 and then transmits them to the indication module 400, and then enters the sleep state to save the power consumption of the main control module 100 and achieve low power consumption of the system.
[0089] The main control module 100 is composed of a main control chip U1 and a peripheral circuit, and the connection structure of the main control chip U1 and the peripheral circuit is specifically referred to Figure 8 and the model of the main control chip U1 is STM32G071CB. Data processing is performed through the main control chip U1 to output a first main control signal, a second main control signal, and a third main control signal for controlling each module.
[0090] In some embodiments, the main control module 100 is further configured to output a second main control signal for adjusting the brightness of the indication module 400. The indication module 400 includes: a driving unit 410, a brightness adjustment unit (not marked in the figure), and an indication unit 430. The driving unit 410 is configured to receive the first main control signal and output a driving signal. The brightness adjustment unit (not marked in the figure) is configured to receive the second main control signal and output a brightness adjustment signal. The indication unit 430 is configured to receive the driving signal and the brightness adjustment signal and output an indication signal.
[0091] Through the driving unit 410, the brightness adjustment unit (not marked in the figure), and the indication unit 430, it is convenient to output an indication signal to prompt the driver of the traffic situation, thereby improving traffic safety.
[0092] Among them, two indication modules 400 are provided, and the two indication modules 400 are respectively located in two different directions of the road to distinguish the colors seen by vehicles on the highway when driving forward and in reverse, so as to remind the driver.
[0093] The indicating unit 430 receives a driving signal to start lighting, and receives a brightness adjustment signal to adjust the brightness. The indicating unit 430 includes 4 indicator lights, and the circuit connection structure of the indicating unit 430 is specifically referred to Figure 9 , through Figure 9 it can be seen that the 4 indicator lights are D3 to D6, and the 4 indicator lights are connected to each other and connected to the driving unit 410 through three pins.
[0094] The driving unit 410 includes: a driving chip U2 and several triodes. The model of the driving chip U2 is specifically WS2811, and the connection of the driving chip U2 and several triodes is specifically referred to Figure 9 . Among them, a pin of the indicating unit 430 is connected to the driving chip U2 through two triodes. Therefore, the driving unit 410 cleverly uses 2 types of triodes in cooperation with each other, so that one driving chip U2 can drive 4 or more indicator lights at the same time, reducing the current consumption of the driving chip U2.
[0095] Among them, the driving chip U2 is connected to the main control chip U1 through the RGB_LED1 pin, so that the driving chip U2 can receive the driving signal through the RGB_LED1 pin. The driving unit 410 is connected to the indicator lights through the LED1R-, LED1G-, LED1R- pins to control the lighting or extinguishing of the indicator lights.
[0096] In some embodiments, the wireless transmission control module 300 is further configured to output a third control signal. The indicating module 400 further includes: a logic gate unit 440, which receives the third control signal and the second main control signal and outputs a judgment signal; the power supply module 200 is configured to receive the judgment signal to control the power supply of the indicating unit 430.
[0097] Specifically, the logic gate unit 440 outputs a judgment signal to the power control unit 240, and the power control unit 240 receives the judgment signal to control the opening and closing of the indicating unit 430. The logic gate unit 440 is connected to the main control module 100 through the MCU_PWM pin to receive the second main control signal through the MCU_PWM pin, and the logic gate unit 440 is connected to the wireless transmission control module 300 through the LORA_POWER_EN pin to receive the third control signal through the LORA_POWER_EN pin.
[0098] Among them, the power control unit 240 is a MOS transistor, the logic gate unit 440 is a NAND gate, and the second main control signal output by the main control module 100 is a PWM signal. Therefore, the NAND gate receives the second main control signal and the third control signal to output a judgment signal, and then the power control unit 240 controls the start or shutdown of the indication unit 430 according to the judgment signal. Since the PWM signal and the third control signal control the switching of the MOS transistor after passing through the NAND gate to achieve the brightness and on / off control of the indicator light, ensuring the synchronization of the blinking frequency and brightness information of the indicator light, so that when adjusting the brightness, the light emitted by the indicator light will not affect the driver, further improving traffic safety.
[0099] For the specific connection of the logic gate unit 440 and the power control unit 240, refer to Figure 10 , through Figure 10 it can be known that multiple power control units 240 are provided, and multiple conversion units 250 are also provided. For the conversion unit 250 connected to the logic gate unit 440, specifically refer to Figure 10 . The power control unit 240 connected to the logic gate unit 440 is composed of the twentieth MOS transistor Q20, and for the circuit connection structure of the power control unit 240, specifically refer to Figure 10 . When the NAND gate outputs a high level, the twentieth MOS transistor Q20 conducts, and then the DC-DC conversion chip U9 outputs a voltage to the indication unit 430 to control the on / off of the indicator light, making the on / off control of the indicator light simple.
[0100] In the state where the indicator light is off, a high level is input to the LED_POWER_EN pin of the NAND gate to cut off the power supply of the indicator light. For the brightness and switch adjustment of the indicator light, the PWM duty cycle of the MCU_LED_PWM pin and the high / low level of the LORA_LED_ON - OFF pin of the NAND gate are used to adjust the brightness and blinking frequency of the indicator light, making the regulation of the indicator light simple.
[0101] In some embodiments, the detection module 500 includes: a geomagnetic detection unit 510, a battery detection unit 520, a temperature detection unit 530, and a light brightness detection unit 540.

[0102] Among them, the geomagnetic detection unit 510 can detect the geomagnetic field change of the current environment to generate a first detection signal, and a geomagnetic algorithm is provided in the main control chip. After receiving the first detection signal output by the geomagnetic detection unit 510, noise filtering is performed, the geomagnetic threshold is adjusted, and then the information and driving conditions of the vehicle passing through the geomagnetic detection unit 510 are judged. The vehicle information includes: driving direction, vehicle type, and the driving conditions include: driving the vehicle in reverse, speeding, low speed, parking, etc. By judging the current traffic conditions based on the vehicle information and driving conditions, and then reporting this situation to the remote background through the wireless transmission control module 300, so that the background can send control instructions according to the current traffic conditions to control the lighting and extinguishing of the indicator lights, so that the driver can master the current traffic conditions and improve traffic safety.
[0103] Among them, the geomagnetic detection unit 510 is composed of a geomagnetic chip U4, and the connection structure of the geomagnetic chip and its peripheral circuit is specifically referred to Figure 11 and the geomagnetic chip U4 is connected to an isolation circuit to prevent current backflow. The geomagnetic chip U4 receives the analog signal formed by the geomagnetic detector detection, and then outputs the analog signal to the main control chip U1 to judge the current traffic conditions of the environment through the main control chip U1.

[0105] The temperature detection unit 530 is mainly used to detect the temperature of the device, that is, to detect the temperature of the indicator light. After the temperature detection unit 530 detects the temperature of the indicator light, it outputs a second detection signal to the main control module 100. The main control module 100 judges whether the current temperature of the indicator light is too high and then reports it to the remote background, so that the remote background can monitor and debug the indicator light to ensure the normal operation of the indicator light.
[0106] Among them, the battery detection unit 520, the temperature detection unit 530 and the light brightness detection unit 540 are respectively connected with an AD conversion unit.

Since the thermistor detects the temperature and outputs an analog signal, the analog quantity is converted into a digital quantity by the AD conversion unit and input to the main control module 100, which is convenient for the main control module 100 to perform data processing.
[0107] The battery detection unit 520 is used to detect the power of the power supply module 200, that is, to detect the power of the lithium-ion battery, so as to judge whether the current power is sufficient. Therefore, after the battery detection unit 520 detects the power of the lithium-ion battery, a third detection signal is formed. The main control module 100 receives the third detection signal to judge the current power of the lithium-ion battery and then reports it to the remote background, so that the remote background can master the current power of the lithium-ion battery and charge the lithium-ion battery to ensure that the system keeps working.

[0109] The light brightness detection unit 540 mainly detects the light where the solar panel is located to judge the current conversion rate of solar energy into electrical energy. Therefore, after the light brightness detection unit 540 detects the optical fiber, a fourth detection signal is generated and sent to the main control module 100. The main control module 100 judges the solar conversion rate according to the fourth detection signal and the power of the lithium-ion battery, and reports the calculation result to the remote background, which is convenient for the remote background to master the conversion situation of the solar panel.

[0112] The following is a reference to Figure 1 and Figure 2 A beacon control system according to an embodiment of the present invention will be described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the invention.
[0113] The solar panel converts solar energy into second electric energy, outputs first electric energy after USB charging, stores the first electric energy and the second electric energy in the lithium-ion battery, and converts the 4.2V voltage in the lithium-ion battery into a 3.3V output voltage through the DC-DC conversion chip U8. When the LORA chip U5 starts to work, after receiving the control instruction from the remote background, it sends it to the main control chip U1. After the main control chip U1 finishes receiving the control instruction, the LORA chip U5 enters the sleep state to save power. The main control chip U1 parses the control instruction into a first main control signal and sends it to the driving unit 410, and parses it into a second main control signal and sends it to the NAND gate U10. When the main control chip U1 finishes sending data, it also enters the sleep state to save power. The second main control signal is a PWM signal. The driving unit 410 converts the first main control signal into a driving signal to drive the indicator light to light up. The NAND gate U10 receives the PWM signal and the third control signal sent by the LORA chip. That is, if the LORA chip U5 sends a high level, the indicator light will not change regardless of the PWM signal. If the LORA chip U5 sends a low level, the indicator light will adjust its brightness according to the PWM signal to synchronize the flashing frequency and on / off of the indicator light. Through the control of the indicator light, the driver is prompted about the current traffic situation, so that the driver can master the current traffic situation and improve traffic safety.
[0114] The main control chip U1 sends a third main control signal to the detection module 500, then the temperature detection unit 530, the geomagnetic detection unit 510, the battery detection unit 520, and the light brightness detection unit 540 are started. The geomagnetic detection unit 510 detects the geomagnetic environment of the current environment and outputs a first detection signal value to the main control chip U1. The main control chip U1 judges the current traffic situation and vehicle information according to the first detection signal, and reports the judgment result to the remote background through the LORA chip U5, so that the remote background can always master the current traffic situation. Moreover, the temperature detection unit 530 detects the temperature of the indicator light, the battery detection unit 520 detects the power of the lithium-ion battery, the light brightness detection unit 540 detects the light, and the main control chip U1 reports the detection signals of each detection unit to the remote background through the LORA chip U5, so that the remote background can master the current traffic, indicator light, power, and light conditions, and output accurate control instructions to improve the safety of beacon control.

[0117] S200. After the wireless transmission control module completes network access, it outputs a second control signal to close the connection between the main control module and the power supply module.
[0118] By controlling the startup or shutdown of the main control module by the wireless transmission control module in different states, the wireless transmission control module and the main control module are started separately to save the power consumption of the main control module and the wireless transmission module, thereby achieving low power consumption of the system.
[0119] In some embodiments, the beacon control method further includes:
[0120] S300. The wireless transmission control module receives and sends a control instruction to the main control module;
[0121] S400. The main control module analyzes the control instruction to output a first main control signal and a second main control signal;

[0123] S600. The indication module is started according to the first main control signal;
[0124] S700. The indication module adjusts the opening / closing and brightness according to the second main control signal and the third control signal.
[0125] Wherein the second main control module is a PWM signal to adjust the brightness of the indication module through the PWM signal, and the startup or shutdown of the indication module is controlled through the third control signal, thereby controlling the blinking frequency of the indication module. Therefore, by inputting the second main control signal and the third control signal to the indication module, the indication module controls the startup and brightness adjustment of the indication module according to the second main control signal and the third control signal, so that the blinking frequency and brightness adjustment of the indication module are synchronized. Among them, the specific operation process of a beacon control method specifically refers to the beacon control system in the first aspect, which will not be elaborated here.
