[0030] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0031] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and shall not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. They are only for the convenience of describing the present invention and simplifying the description, and shall not indicate or imply that the referred device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they shall not be understood as limiting the present invention.

[0032] like Figure 1 As shown in the system logic block diagram, the present application provides a system for collecting and transmitting weather information for an event, comprising a main control module 1, a data collection module 2, and a display screen 3. The main control module 1 is communicatively connected to a host computer 4 via a first transmission module 5 and a second transmission module 6, and the host computer 4 is connected to the main control module 1; the data collection module 2 is connected to the main control module 1 for collecting weather information; the display screen 3 is connected to the main control module 1 for displaying weather information; and the host computer 4 includes a judgment module for comparing the data transmitted by the first transmission module 5 and the second transmission module 6, intercepting the data transmitted by both when the data are inconsistent, and displaying the data transmitted by both on the display screen 3 when the data are consistent.

[0033] In one specific embodiment, data acquisition module 2 collects meteorological information about the playing field, including but not limited to temperature, humidity, wind direction, wind volume, and rainfall. This information is then transmitted to main control module 1, which then transmits the data to host computer 4 via first and second transmission modules 5 and 6. First transmission module 5 transmits data via wired transmission, while second transmission module 6 transmits data via wireless communication. The system is also connected to a display screen 3 for intuitive display of meteorological data.

[0034] More specifically, during an event, data collection is set to occur every 2 seconds, or 30 times per minute. The judgment module compares the data transmitted by the two channels in real time to ensure that only consistent data is further processed and displayed. If there are three instances of inconsistency between the data transmitted by the first transmission module 5 and the second transmission module 6, only the 27 instances of consistent data will be recorded. This prevents erroneous data from interfering with the statistical database and enhances data accuracy. Accurate data enables event organizers to make more informed decisions, such as adjusting the schedule based on weather changes or implementing emergency measures, thereby improving the quality of event management.

[0035] In addition, through two independent transmission modules, the system can provide fault tolerance during data transmission. Even if one module fails, is interfered with or other factors cause it to stop working, the other module can still ensure data transmission, thereby greatly improving the stability and flexibility of the entire system.

[0036] refer to Figure 2 The main control module 1 includes a single-chip microcomputer chip U2 of type STC8H8K64U, and the first serial port of the single-chip microcomputer chip U2 (such as Figure 1 Serial port 1) is used as the configuration port, and the second serial port (such as Figure 1 The serial port 2) is connected to the data acquisition module 2, and the third serial port (such as Figure 1 The serial port 3) is connected to the first transmission module 5, and the fourth serial port (such as Figure 1 The serial port 4 is connected to the second transmission module 6. The use of the single-chip microcomputer chip STC8H8K64U can quickly process the collected meteorological data. The single-chip microcomputer provides multiple serial ports, which can achieve effective communication with the data acquisition module 2, the first transmission module 5 and the second transmission module 6, making data transmission more reliable and efficient.

[0037] refer to Figure 1 and Figure 2 Data acquisition module 2 includes a MAX481 transceiver chip U4 and several sensors. The MAX481 transceiver chip features low power consumption and high transmission speeds, making it suitable for extended outdoor events. It also boasts strong anti-interference capabilities and protection features, enhancing the reliability and stability of data acquisition module 2. The MAX481 supports multiple device connections and can connect to multiple sensors.

[0038] refer to Figure 1 and Figure 2 , several sensors use the MODBUS-RTU protocol to communicate with the STC8H8K64U microcontroller chip U2 mentioned above. Through the MODBUS-RTU protocol, the system can achieve standard serial communication. This protocol is widely used in industrial environments and has strong stability and anti-interference capabilities. The last two digits of the MODBUS-RTU standard format data are the CRC16 check bits of the valid data. According to this protocol, the data is packaged and transmitted, and combined with the checksum comparison of the host computer 4 software system to ensure the accuracy of the acquired data. At the same time, it also makes the subsequent increase and decrease of sensor types and data acquisition simple and clear. By not connecting the corresponding sensor, unused data can be obtained without changing the microcontroller program, making this system highly versatile and flexible.

[0039] In a specific embodiment, the above-mentioned sensors include temperature and humidity sensors, wind speed sensors, wind direction sensors, air quality sensors, ultraviolet sensors, and rainfall sensors, and all use the RS485 interface. RS-485 allows multiple devices to be connected to the same bus, enabling multi-point communication, and the RS-485 interface supports long-distance and high-speed data transmission. It can usually maintain reliable communication within a range of several hundred meters, which is suitable for the layout of weather stations at large event venues. Furthermore, the sensors are all equipped with dustproof and waterproof structures to adapt to harsh environments and improve reliability. In addition, sensors such as dust sensors can also be set up.

[0040] The baud rate of the above sensors is uniformly set to 9600, which can simplify the communication configuration and debugging process of the system. As a common serial communication rate, 9600 baud rate helps compatibility between different devices and facilitates subsequent data processing and storage.

[0041] refer to Figure 1 and Figure 2 It also includes a button SW to clear rainfall data, allowing users to reset rainfall calculations at a specific time point, making it easier to record and analyze periodic data, especially for the collection and recording of meteorological data for multiple events.

[0042] like Figure 2 As shown, in this system, the first transmission module 5 includes a transceiver chip U3 of model SP3232e and its peripheral circuit, and the output end of the peripheral circuit is connected to the above-mentioned host computer 4; the second transmission module 6 includes a wireless transmission chip U1 of model ESP8266 and its peripheral circuit.

[0043] As an extension, the system also has a built-in Web server (not shown in the figure), allowing users to monitor real-time meteorological data through their mobile phones or mobile terminals.

[0044] Alternatively, a 32-bit STM32 microcontroller (such as the STM32F103C8T6) could be used to replace the existing microcontroller. The STM32 microcontroller is based on an ARM core and offers enhanced processing performance. Furthermore, this solution uses a variety of sensors with I2C communication interfaces to collect meteorological data, but waterproofing is difficult to achieve. I2C communication is typically suitable for short distances and may affect the stability and reliability of communication for sensors requiring long-distance communication.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
