Controlled by the Android OS-based APP "KC Smart Helmet" 4.2.1. APP installation The KC-N901 Smart Helmet can be controlled by the Android OSbased APP "KC Smart Helmet". 1) Download APP： A.
Figure 10. The product identification card on the side of the carrying bag B. Go to the official website of KC Smart Helmet (https://www.kcwearable.com) and download it from the "Support" section. 2) Name of the installation package: “AI_PHONE_v1.1.33.2-15_2_release.apk” 4.2.2. Bluetooth Connection These steps need to be executed only for the first time connection between the smart phone and the smart helmet; 1) Turn on bluetooth on the smart phone 2) Open “KC Smart Helmet” App.
Figure 11. Bluetooth pairing pop-up dialog box and parameter setting page 5) If the connection failed, please try the following: A. Inspect the start-up state of the helmet and device and ensure that the Bluetooth is enabled and is not connected to other Bluetooth device. B. Press and hold the Bluetooth button on the left of the helmet, and click “Pair”again. C. If the problem is still unresolved, please restart the helmet and “KC Smart Helmet” APP and try it again.
Step 1: Open “KC Smart Helmet” App and connect the helmet through bluetooth; Step 2: The calibration assisting person stands 1 meter in front of the thermal imager. Step 3: Adjust the center of the screen to target the ears or forehead of the assisting person, and click “One-Click Calibration”. The quick calibration is completed as complete” prompting on the screen. Figure 12.
Temperature measurement can be started till 5~10 minutes after the boot when the measurement accuracy has already been stabilized. When the thermal imaging module is calibrated, it clicks every few seconds, which may be accompanied by a short-time video lag. During the whole calibration process, the center of the screen must be targeted at the uncovered forehead or ears of the assisting person. Otherwise, the calibration result may leave a large margin error.
Figure 13. Parameter setting interface of manual calibration Note: Temperature measurement can be started till 5~10 minutes after the boot when the measurement accuracy has already been stabilized.
Figure 14. Rainbow mode VS Iron Gray mode 4.2.6. Working modes The KC-N901 basic version provides only two working mode of temperature measurement mode” and “large-crowd “single-person temperature measurement mode”. While the AI version implements nine additional modes. The specific working mode can be confirmed through the "Mode" setting page in the APP. Figure 15.

Figure 21. Single-person temperature measurement mode The default warning range is 37.3 °C ~ 42 °C. When the highest temperature detected in the center of the screen locates in this range, it will trigger an audible and visual alarm. This mode can be used for accurate temperature measurement in all scenarios, particularly suitable for the fast temperature measurement outdoors at daytime or in environment with complicated thermal radiation sources.
Figure 22. Large-crowd temperature measurement mode Note： The thermal imaging module could not distinguish the properties of the imaging objects at current version. If the lamp box, water cup or metal parts exposed to direct sunlight appear in the screen, the temperature value of these parts may be displayed and the readings will be affected. Therefore, single-user mode is recommended for the complicated environment. 4.4.3.

5. Cautions 5.1. Battery Usage Under any circumstances, please do not modify the built-in battery by yourself to avoid causing damage to the battery. Do not put the battery into fire or any other high temperature place, otherwise it will cause fire or explosion of the battery. The battery cannot be used for other purposes. Do not use any damaged charger or battery.
6. Frequently Asked Questions 6.1. Hardware FAQ 6.1.1. Unable to boot 1) Make sure the battery is installed correctly. 2) Connect the power cord to charge. If the power indicator is on, charge the helmet for at least 20 minutes to ensure that the battery has enough power to power on. If the power indicator does not light on after power cable connection, the power supply module may be damaged. 3) Press and hold the power button to try to power on.
6.1.5. Short battery life Under normal circumstances, the battery life of helmet is up to 5 hours for temperature measurement ; and the battery life will be shortened to 3 hours in heavy load modes when the visible light camera and infrared thermal imaging module work at the same time, e.g. in the license plate recognition or QR code recognition mode. A possible cause for the significant shorter battery life is that the battery is not fully charged.
6.2.3. Questions about wearing adjustment 1) Q: How many places can I adjust when wearing the smart helmet? A: A. Strap Length B. The optical waveguide AR glasses are installed on the safety goggles, and the AR glasses position can be adjusted by adjusting the AR glasses arm. (As the space for extending and retracting of the AR glasses is limited, large-range adjustment of the AR glasses on the safety goggles should be avoided).
