[0016] Preferably, the back of the base plate 1 is provided with anti-slip pads 19 at intervals.

[0017] like Figure 4 and Figure 5 As shown, a high-precision foot shape detection track based on the aforementioned high-precision foot shape detection plate includes a foot shape detection plate 10, several data acquisition plates 20, and an inclined guide plate 30. The foot shape detection plate 10 and the several data acquisition plates 20 are connected sequentially by hinges 21. The inclined guide plate 30 is respectively disposed at both ends of the foot shape detection plate 10 and the several data acquisition plates 20. The data acquisition plate 20 includes a base plate, a PU surface, several pressure sensors, and a printed circuit board. The printed circuit board is laid on the surface of the base plate. The several pressure sensors are arranged in an array on the printed circuit board with a dot density greater than 12 per square centimeter. The PU surface is laid on the surface of the arrayed pressure sensors. The detection signals of the several pressure sensors of adjacent data acquisition plates are transmitted to the microprocessor control motherboard 5 of the foot shape detection plate 10 via a cascade interface 22.

[0018] Preferably, the cascading interface 22 is located on the side of the base plate of each data acquisition board 20.

[0019] The pressure sensor in this foot type detection plate is a 4096-level pressure sensitivity sensor with a dot density of more than 12 per square centimeter, which can capture micro-pressure changes (such as risk points for diabetic foot ulcers); the array layout of the pressure sensor forms a 3D pressure grid, and simultaneously generates 2D / 3D plantar pressure distribution maps.

[0020] The USB port enables high-speed data transmission; the power indicator, data acquisition indicator, and data transmission indicator use green, yellow, and red three-color LED indicators, with green indicating normal operation, yellow indicating data abnormality, and red indicating hardware failure, providing real-time status feedback.

[0021] The main body of this foot-type detection plate features an anti-slip frame design, a built-in pressure sensor array, and a microprocessor control motherboard integrated into the base plate, which connects to a USB port to transmit detection data; a three-color LED indicator is embedded in the side edge of the base plate.

[0022] This foot type detection board and track can perform static and dynamic detection modes respectively. In static mode, the arch index, foot length / width, and pressure balance can be calculated in 3 seconds to assist in the diagnosis of flat feet / high arches. In dynamic mode, gait analysis can be performed in real time to capture the peak pressure points during walking for sports injury prevention.

[0023] The walkway uses cascaded data acquisition boards and foot type detection boards connected in series. The data acquisition boards use cascaded interfaces to connect the pressure sensor detection signals and finally transmit them to the microprocessor control motherboard of the foot type detection board for dynamic mode detection. The cascaded mode can be 1+1, 1+2 or 1+3 cascades of data acquisition boards and foot type detection boards to adapt to various detection environments and detection needs.

[0024] The application of this foot type detection board and walkway increases detection efficiency by 300%, and can output a complete detection report (including pressure heat map, foot type classification, and health advice) within 10 seconds, with an accuracy rate of >95%. The array of pressure sensors identifies abnormal points through micro-current / voltage changes, improving detection accuracy.

[0025] During foot type detection, the user stands on the foot type detection board / walks on the path. The pressure sensor array collects pressure data, selects the detection mode, generates arch index / foot type parameters through static detection, and analyzes the pressure trajectory of the gait cycle through dynamic detection. The collected pressure data is transmitted to the microprocessor control motherboard via the printed circuit board. The microprocessor control motherboard generates a detection report through the foot pressure analysis program and outputs it to the host computer via the USB port. In practical applications, place the foot type detection board on a level, stable surface, ensuring the detection board and board surface are clean and free of debris. Connect the foot type detection board to the host computer using a USB data cable, turn on the power switch, and wait for the system to start. After powering on, the foot type detection board performs a power-on self-test. After the self-test is complete, it enters standby mode. In static mode, the subject removes their shoes and stands on the foot type detection board, maintaining a natural standing posture. The data acquisition indicator light flashes to indicate the start of pressure data acquisition. Maintain a still state for 10-15 seconds or complete the actions required for testing. Avoid body shaking during data acquisition. The acquired pressure data is transmitted via the printed circuit board to the microprocessor control motherboard. The microprocessor control motherboard uses its built-in foot pressure analysis program to generate a foot type detection report and transmits the acquired pressure data and foot detection report to the host computer for storage and printing via the USB port. During this process, the data transmission indicator light flashes; after the transmission is complete, the flashing stops and the light remains constantly on. During dynamic mode detection, the subject stands barefoot on the inclined guide plate at the front of the trail and walks along several cascaded data acquisition plates and foot shape detection plates to the inclined guide plate at the end of the trail. During this process, the pressure data collected by the cascaded data acquisition plates and foot shape detection plates are transmitted to the microprocessor control motherboard. The microprocessor control motherboard obtains a gait detection report through the built-in foot pressure analysis program and transmits it to the host computer for storage and printing via USB port.

[0026] This foot type detection board and walkway can be applied in the medical field to provide risk warnings for diabetic foot ulcers and other foot diseases (identified by uneven pressure distribution); when applied to the footwear customization industry, it can generate 3D models of shoes or insoles based on foot length, width, and pressure point data to achieve a perfect match between foot type and shoes or insoles.

[0027] This high-precision foot shape detection board and walkway is a professional foot pressure data acquisition and analysis device. It adopts a high-precision sensor array to collect real-time foot pressure distribution data for applications such as foot health assessment, gait analysis, and custom shoe insoles.
