[0030] III. Beneficial Effects

[0031] As can be seen from the above technical solution, the present invention has at least one of the following beneficial effects compared to the prior art:

[0032] ① Cane triggering reduces false alarm frequency

[0033] In this invention, the triggering condition is limited to "the signal emitted by the cane", rather than simple stepping or gravity triggering, which significantly reduces false alarms (passersby and wheels running over the can trigger existing pressure-based voice bricks).

[0034] Specifically, a "point-to-point" recognition relationship is established using proximity sensing (magnetic, metallic, radio frequency) to achieve "the brick only responds when a visually impaired person carrying a cane arrives"; this selective triggering suppresses the broadcast overload caused by scene noise (raindrops, footsteps, strollers, etc.), thereby avoiding information fatigue and urban noise pollution.

[0035] ② The cavity design of "box-shaped structure + top cover" improves reliability and maintainability.

[0036] In this embodiment, the box structure and the top cover together form a closed cavity, which improves reliability and maintainability: the cavity design of "box structure + top cover" isolates the sensing device from the external environment, making it easy to maintain in a waterproof, dustproof, and impact-resistant manner, while allowing the internal electronic modules to be replaced or repaired without damaging the floor tiles.

[0037] ③ Modular functionality, suitable for standardized mass production and later upgrades:

[0038] By separating the triggering and sensing functions and connecting them via signals, the electronic devices are packaged in a standardized manner. Modules can be replaced according to different scenarios (such as upgrading to a network module or a higher brightness light), which aligns with the trend of smart city expansion.

[0039] ④ Dual sound and light alerts enhance safety.

[0040] The dual audio-visual prompts serve two types of users simultaneously: those with hearing and those with peripheral vision / vehicle recognition. They not only alert blind people but also alert surrounding vehicles / pedestrians to the blind person's location, thus improving pedestrian safety.

[0041] ⑤ Multiple components work together to provide comprehensive guidance for visually impaired individuals.

[0042] In this invention, the white cane body, the triggering device body, the tactile paving brick body, the sensing device body, and the top cover work together. When a visually impaired person stops on the top of the tactile paving brick body and the top cover, the triggering device of the white cane triggers the tactile paving brick sensing device. The sensing device body, in conjunction with the voice broadcaster, emits a voice reminder based on the current traffic light changes and the number of seconds, thus conveniently reminding the visually impaired person whether they can walk.

[0043] ⑥ Introduce warning lights to provide a warning to other road users besides visually impaired individuals.

[0044] In this invention, by setting up the white cane body, triggering device body, tactile paving brick body, sensing device body, warning light and transparent protective plate, when a visually impaired person stops and waits on the top cover and the top of the tactile paving brick body at night, the triggering device of the white cane will trigger the tactile paving brick sensing device in conjunction with the white cane. Its warning light can emit a warning light source around the top cover, thereby facilitating observation by external vehicles and effectively reminding people. Attached Figure Description

[0050] Figure 6 for Figure 5 The diagram shows the structure of the triggering device in a trigger-type white cane. Detailed Implementation

[0051] Traditional gravity-triggered tactile paving is prone to false alarms when pedestrians or vehicles pass by. This invention changes the triggering mechanism to a two-way collaborative sensing system between the cane and the tactile paving, achieving a triple effect of accurate triggering, false alarm suppression, and communication extension. The cane acts as the active triggering unit, and the tactile paving acts as the passive receiving unit. Short-range inductive communication (such as magnetic induction, metal induction, radio frequency, or near-field communication) is established between the two. When a visually impaired person actually enters the tactile paving area, the system automatically identifies and triggers voice prompts and warning lights.

[0052] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0053] A first aspect of the present invention provides a trigger-operated white cane. In one exemplary embodiment of the present invention, a trigger-operated white cane is provided. Figure 5 This is a schematic diagram of the trigger-type white cane according to an embodiment of the present invention. Figure 6 for Figure 5 The diagram shows the structure of the triggering device in a trigger-type white cane. As shown in the attached figure, the trigger-type white cane of this embodiment includes: a white cane body 14; and a triggering device body 15, which is disposed on the upper part of the tip of the white cane body.

[0054] Those skilled in the art should understand that the cane in this embodiment includes both canes used by blind people and assistive canes used by visually impaired people with partial visual impairment, and are collectively referred to as "canes" in this invention.

[0055] In this invention, the triggering device and the white cane interact with each other through one of the following methods: magnetic induction triggering, metal induction triggering, and radio frequency induction triggering.

[0056] In this embodiment, the triggering device and the white cane interact via magnetic induction. Specifically, the triggering device body 15 contains an electronic trigger 16. The electronic trigger 16 includes a microcontroller, a transmitting coil, a metal induction plate, or an NFC transmitting chip. The electronic trigger 16 is powered by a rechargeable lithium battery and contains a low-power control chip. This electronic trigger 16 actively emits magnetic field signals.

[0057] During use, when the tip of the cane is less than 20 cm from the ground or touches the surface of the tactile paving bricks, the electronic component trigger 16 emits a periodic trigger signal with a frequency of 10–30 kHz (magnetic induction) or 13.56 MHz (NFC).

[0058] Corresponding to the side of the white cane, on the side of the tactile paving, a triggering device electrically connected to the sensing device is embedded in the four corners or center of the top cover. This device could be an induction receiving coil or a metal sensing plate. When a magnetic field disturbance or identification code packet is detected from the trigger-type white cane, the triggering device sends a trigger signal to the sensing device; the sensing device then activates the voice broadcast unit to indicate the current traffic light status or countdown; if it is nighttime, a warning light will illuminate simultaneously.

[0059] In this embodiment, the trigger module on the side of the tactile paving bricks only responds when a specific identification code or a signal pattern of a metal piece on a white cane is detected, preventing accidental triggering caused by pedestrians carrying metal objects. Furthermore, the interaction design employs a sensing area with a short-range effective radius ≤0.5 m, ensuring that it only responds when triggered at close range by the white cane.

[0060] In this invention, the triggering condition is limited to "the signal emitted by the cane," rather than simple stepping or gravity triggering, significantly reducing false alarms (pedestrians and vehicle wheels can trigger existing pressure-based voice bricks). Specifically, a "point-to-point" recognition relationship is established using proximity sensing (magnetic, metallic, radio frequency), ensuring that "the brick only responds when a visually impaired person carrying a cane arrives." This selective triggering suppresses the broadcast overload caused by scene noise (raindrops, footsteps, strollers, etc.), thereby avoiding information fatigue and urban noise pollution.

[0061] A second aspect of the present invention provides a sensor-activated tactile paving brick. In one exemplary embodiment of the present invention, a sensor-activated tactile paving brick is provided. Figure 1 This is a schematic diagram of the overall structure of the sensor-activated tactile paving bricks according to an embodiment of the present invention. Figure 2 for Figure 1 The diagram shows the disassembled structure of the sensor-activated tactile paving bricks. Figure 3 for Figure 1The diagram shows the structure of the top cover in the sensor-activated tactile paving bricks. Figure 4 for Figure 1 The diagram shows the structure of the sensing device body in the sensor-operated tactile paving brick. As shown in the figure, the sensor-operated tactile paving brick in this embodiment includes:

[0062] The tactile paving brick body 1 has a cavity inside, including: a box-shaped structure with an upward opening; and a top cover 7 that fits into the upper opening of the box-shaped structure, the two forming a cavity.

[0063] The triggering device is installed on the tactile paving brick itself and receives the triggering signal emitted by the white cane;

[0064] A sensing device, whose signal is connected to a triggering device, emits a warning signal by sound and / or light after the triggering device receives a trigger signal.

[0065] In this embodiment, the box structure and the top cover together form a closed cavity, which improves reliability and maintainability: the cavity design of "box structure + top cover" isolates the sensing device from the external environment, making it easy to maintain in a waterproof, dustproof, and impact-resistant manner, while allowing the internal electronic modules to be replaced or repaired without damaging the floor tiles.

[0066] In this embodiment, the box-shaped structure of the tactile paving brick body is a cubic box-shaped structure; the top cover is rectangular. In the tactile paving brick body, the top cover 7 has reinforcing ribs arranged at equal intervals inside, and a tactile sensing protrusion 10 is provided in the middle of the top surface of the top cover 7.

[0067] In this invention, the triggering device and the white cane interact via one of the following methods: magnetic induction triggering, metal induction triggering, radio frequency induction triggering, or near-field communication. In this embodiment, triggering devices 13 are positioned at the four corners of the top surface of the top cover. The triggering devices 13 interact with the electronic component trigger 16 in the white cane via radio frequency induction triggering. For details, please refer to the previous description; it will not be repeated here.

[0068] In this embodiment, the sensing device includes: a sensing device body 2, disposed within a cavity; an electronic component receiver 3, fixed to the sensing device body and connected to a triggering device; an alarm mechanism, connected to the electronic component receiver; and a battery pack, disposed within the sensing device body, for providing power to the electronic component receiver 3, the alarm mechanism, etc. Upon receiving a trigger signal, the electronic component receiver 3 controls the alarm mechanism to emit an alarm signal using sound and / or light. The alarm mechanism includes a voice alarm mechanism and an optical alarm mechanism.

[0069] It should be noted that in this embodiment, the trigger and sensing are separated and connected by signals, so that the electronic device is packaged in a standardized manner. The module can be replaced according to different scenarios (e.g., upgraded to a network module or a higher brightness light), which is in line with the trend of smart city expansion.

[0070] Regarding the voice warning mechanism, the electronic component receiver 3 is connected to the intersection traffic light system. It receives current traffic light status information from the system, such as the change from red to green and the remaining seconds. The electronic component receiver 3 then communicates this information to visually impaired individuals via the voice warning mechanism. Furthermore, the electronic component receiver also sends a "Visually impaired person, please cross" message to the intersection traffic light system. The traffic light system uses this message to adjust the traffic light logic, facilitating passage for visually impaired individuals.

[0071] Specifically, voice announcers 4 are fixedly installed on both sides of the sensing device body 2. A connector 5 is provided in the center of the top surface of the voice announcer 4. A power cord 6 is installed inside the connector 5, and one end of the power cord 6 is electrically connected to one side of the electronic component receiver 3. Through the setting of the power cord 6 and the connector 5, when the sensing device body 2 has completed data detection, its power cord 6 can transmit the data to the inside of the voice announcer 4, making it convenient for the voice announcer 4 to provide prompts to visually impaired users.

[0072] Those skilled in the art will understand that, in this embodiment, two voice players are provided on the side of the sensing device body. However, in other embodiments of the present invention, one, three, four, or more voice players may be provided, and the positions of the voice players may be adjusted as needed.

[0073] Regarding the optical warning mechanism, a top cover 7 is snapped onto the top surface of the tactile paving brick body 1, and a continuous receiving groove is formed on the top edge of the top surface of the top cover 7. A warning light 8 is embedded in the receiving groove. The warning light is a strip-shaped warning light that extends within the receiving groove. A transparent protective plate 9 is provided at the edge of the top surface of the warning light 8, covering the receiving groove.

[0074] Reference Figures 1 to 4 A sealing strip 11 is provided at the edge of the top surface of the boxed structure. A waterproof membrane is attached to the outer surface of the sealing strip 11. A protective plate 12 is provided on the outer surface of the tactile paving brick body 1. An anti-oxidation coating is attached to the side surface of the protective plate 12. The protective plate 12 and the sealing strip 11 facilitate external waterproofing of the tactile paving brick body 1 by personnel.

[0075] Specifically, by setting up the tactile paving brick body 1, the warning light 8 and the transparent protective plate 9, when visually impaired people stand and wait on the top of the cover 7 and the tactile paving brick body 1 at night, the warning light 8 can emit a warning light source around the top cover 7, thereby facilitating observation by external vehicles and effectively reminding people.

[0076] Working principle: When a visually impaired person uses the sensor-activated tactile paving bricks, as they walk along the remaining tactile paving to the top surface of the tactile paving brick body 1, the triggering device senses the periodic trigger signal emitted by the electronic component trigger 16 in the white cane. The sensing device body 2 can detect the current traffic light countdown and status, and the voice broadcaster 4 can then provide a prompt on the current traffic light status. Furthermore, when a visually impaired person walks to the top of the cover 7 at night, the warning light 8 can emit a light source on the top of the cover 7, which in turn can emit a light source under the feet of the visually impaired person, thus conveniently reminding passing vehicles and pedestrians at night.

[0077] A third aspect of the present invention provides a tactile paving coordination system. In an exemplary embodiment of the present invention, the tactile paving coordination system includes: a trigger-type white cane, which is the trigger-type white cane in the previous embodiment; and a prompting tactile paving brick, which is the inductive tactile paving brick in the previous embodiment.
