TECHNICAL FIELD

[0001] The present application relates to the field of orienteering timing technology, in particular to a smart clock-in terminal device supporting WiFi and Bluetooth wireless communication. BACKGROUND

[0002] Orienteering is a sport that relies on a map and compass to find checkpoints in the wild. During the competition, athletes need to visit each checkpoint in turn and clock in on the clock-in device to complete the competition timing.

[0003] The current orienteering clock-in device on the market mainly uses the following technical solutions:

[0004] Clock-in function: using RFID radio frequency identification technology to record visit information by reading the RFID card carried by the athlete;

[0005] Data transmission: export the clock-in data to the computer through wired mode (such as USB data line);

[0006] Time synchronization: using a special time calibration device or manual method to calibrate the time of each clock-in point;

[0007] Score output: print the competition results by connecting a wired printer.

[0008] The above prior art solutions have the following disadvantages: inconvenient data transmission, manual collection of data from each clock-in point after the competition, wired export, low efficiency; difficult to calibrate time, scattered field points, difficult to unify the time of each device, affecting the fairness of the competition; complicated score output, need to carry a printing device and a data line, complex on-site operation; dependent on a transfer device, some solutions need to develop an additional transfer device to realize wireless transmission, increasing cost and complexity. SUMMARY

[0009] In view of the deficiencies of the prior art, the present application provides an orienteering smart clock-in terminal, which integrates WiFi and Bluetooth wireless communication functions to realize convenient transmission of clock-in data, automatic time calibration and wireless printing, and improve the organization efficiency and user experience of orienteering competition.

[0010] The technical solutions of the present application are as follows:

[0011] An intelligent check-in terminal for orienteering includes: a main control module, employing an embedded processor supporting dual-mode WiFi and Bluetooth communication, responsible for overall control and data processing; an RFID identification module, used to read the RFID cards carried by athletes, identify the athletes, and record the check-in time; a WiFi communication module, used to connect to a wireless network to achieve SNTP network time synchronization and remote data transmission; a Bluetooth communication module, used to connect to a Bluetooth printer to achieve wireless printing of competition results; a power management module, providing power supply and charging / discharging management functions; and an audio-visual prompt module, providing operation feedback to the user through a buzzer and LED lights. Core Functions

[0012] WiFi Time Synchronization Function: The device connects to a network time server (NTP / SNTP) via WiFi to automatically obtain standard time for synchronization, ensuring consistent and accurate times at all check-in points. It also supports mobile hotspot AP mode, allowing time synchronization even in environments without a fixed network connection.

[0013] WiFi data transmission function: Check-in data can be uploaded to the grade statistics system in real time via WiFi, supporting both local area network grade statistics system and cloud grade statistics system modes, eliminating the need for manual data collection.

[0014] Bluetooth printing function: Supports connection to Bluetooth portable printers for on-site wireless printing of competition results, without the need for data cables or additional equipment.

[0015] Management Mode Functions: Access management mode by swiping a specific management card. In management mode, you can perform operations such as WiFi network configuration, time synchronization, uploading grade data, and downloading configuration files. Management mode supports automatic exit by swiping the management card again or upon completion of the task. Attached Figure Description
