[0002] In the field of rail transit, such as subways and trains, anti-slip flooring and safety monitoring are crucial. Traditional anti-slip pads primarily focus on providing slip resistance by using materials with a high coefficient of friction to increase the friction between the ground and the sole of the shoe, thereby preventing slips and falls. However, with the increasing demands for intelligence and safety, simply providing anti-slip functionality is no longer sufficient to meet the needs of modern rail transit.

[0003] In practical applications, the door areas of rail transit vehicles are the main passageways for passengers to board and alight, and also high-risk areas for slip-and-fall accidents. To ensure passenger safety, in addition to flooring materials with good anti-slip properties, a device is also needed to monitor passenger flow and the placement of heavy objects in real time, so that appropriate safety measures can be taken when necessary.

[0004] Furthermore, due to the unique operating environment of rail transit vehicles, anti-slip stickers also need to have good waterproof performance. During rainy or snowy weather, or during cleaning, water can easily accumulate on the ground. If the anti-slip stickers are not waterproof, moisture may seep into them, damaging electronic components and affecting their normal use. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a pressure-sensitive anti-slip sticker, such as... Figures 1-3 As shown, the device includes a base plate 1, with an anti-slip layer 3 installed on top of the base plate 1. A pressure sensor 2 is installed inside the base plate 1 at the bottom surface of the anti-slip layer 3. A signal line 4 is connected to one side of the pressure sensor 2, which is then connected to a backend device. Waterproof partitions 11 are installed on both sides of the pressure sensor 2 inside the base plate 1. The pressure sensor 2 is positioned near the front of the rail transit vehicle door. The base plate 1 serves as the basic support structure for the entire anti-slip patch, ensuring its stability and durability. The anti-slip layer 3, installed on top of the base plate 1, is made of a high-friction material, effectively increasing the friction between the ground and the shoe sole, significantly improving anti-slip performance. The pressure sensor 2, installed inside the base plate 1 at the bottom surface of the anti-slip layer 3, can monitor the pressure changes on the anti-slip patch in real time, providing reliable data support for safety monitoring. The signal line 4 connected to one side of the pressure sensor 2 is used to transmit the signal detected by the pressure sensor 2, facilitating subsequent data processing and analysis. The waterproof partition 11 installed inside the bottom plate 1 on both sides of the pressure sensor 2 effectively prevents moisture from seeping into the bottom plate 1, protects the pressure sensor 2 and other electronic components from moisture, and ensures the long-term stable operation of the anti-slip pad.

[0025] In this embodiment, a pad 14 is provided between the bottom of the pressure sensor 2 and the inner wall of the bottom plate 1. The pad 14 effectively isolates the pressure sensor 2 from direct contact with the inner wall of the bottom plate 1, avoiding wear or uneven pressure distribution problems that may occur due to direct contact, ensuring the stability and accuracy of the pressure sensor 2, and also facilitating the installation and replacement of the pressure sensor 2. The pressure sensor 2 is a strain gauge pressure sensor. This type of sensor is a sensitive device that converts the strain change on the measured object (such as the pedestrian pressure borne by the anti-slip sticker) into an electrical signal, and is one of the main components of a piezoresistive strain sensor. The working principle of the strain gauge pressure sensor is based on the resistance strain effect. When a metal conductor (such as a resistance strain gauge) is subjected to an external force, its length and cross-sectional area will change, thereby causing a change in the resistance value. Specifically, if the metal wire is stretched by an external force, its length increases and its cross-sectional area decreases, and the resistance value will increase; conversely, if the metal wire is compressed by an external force, its length decreases and its cross-sectional area increases, and the resistance value will decrease.

[0026] In this invention, when a pedestrian walks on a treadmill equipped with anti-slip pads, the pressure on the treadmill is transmitted to the strain gauge pressure sensor 2. The resistive strain gauges inside the sensor deform accordingly, causing a change in resistance. This change in resistance is usually small; therefore, the strain gauges are typically arranged in a strain bridge circuit and amplified by a subsequent instrumentation amplifier. The amplified electrical signal is transmitted to an external device for digital processing and then sent to the intelligent control center.

[0027] Specifically, a water collection chamber 12 is provided on the side of the waterproof partition 11 away from the pressure sensor 2. A drain hole 13 is provided at the top of the water collection chamber 12, and a drain outlet is provided on one side of the water collection chamber 12. A sealing plug 121 is installed at the drain outlet. The design of the water collection chamber 12 provides a collection space for moisture that seeps into the bottom plate 1, effectively preventing moisture from corroding electronic components such as the pressure sensor 2. The drain hole 13 allows moisture to enter the water collection chamber 12, while the combination of the drain outlet and the sealing plug 121 facilitates the drainage of accumulated water and sealing maintenance, ensuring the waterproof performance of the anti-slip pad.

[0028] Furthermore, notches are provided at the bottom of both sides of the anti-slip layer 3, and sponge pads 31 are adhered inside the notches, covering the top of the drainage holes 13. The sponge pads 31 not only cover the drainage holes 13, maintaining the flatness of the anti-slip patch surface, but also have good water absorption, absorbing and guiding the infiltrated water into the water collection tank 12, further improving the waterproof effect of the anti-slip patch.

[0029] Furthermore, a warning sign 32 is installed on the top side of the anti-slip layer 3. The warning sign 32 visually reminds people of the presence of the anti-slip pad and its safe use, enhancing the practicality and safety of the product. The warning sign 32 is particularly effective in areas with high pedestrian traffic or potential safety hazards.

[0030] Furthermore, the bottom of the baseboard 1 is coated with an adhesive layer, which fixes the baseboard 1 to the ground. The adhesive layer allows the baseboard 1 to be easily and firmly fixed to the ground without the need for additional fasteners or tools, improving construction efficiency and the stability of the anti-slip tape.

[0031] Furthermore, the anti-slip layer 3 is made of rubber, and the gaps between the sides and bottom of the anti-slip layer 3 and the sponge pad 31 are filled with waterproof adhesive. The rubber material of the anti-slip layer 3 provides excellent elasticity and wear resistance, resulting in superior anti-slip performance. The waterproof adhesive effectively seals the gaps between the anti-slip layer 3 and the sponge pad 31, preventing moisture penetration and further enhancing the waterproof performance of the anti-slip pad.

[0032] Furthermore, a waterproof layer is fitted over the outside of signal line 4. This waterproof layer provides additional protection for signal line 4, preventing moisture from corroding and damaging it, and ensuring the stability and reliability of signal transmission.

[0033] When using this pressure-sensitive anti-slip patch, the bottom plate 1 serves as the basic support structure, ensuring the stability and durability of the patch. The anti-slip layer 3 installed on top of the bottom plate 1 is made of a high-friction material. When a person or object steps on the patch, the anti-slip layer 3 effectively increases the friction between the ground and the sole of the shoe or the bottom of the object, significantly improving the anti-slip performance and preventing slipping accidents.

[0034] A pressure sensor 2, installed inside the bottom plate 1 on the bottom surface of the anti-slip layer 3, can monitor changes in pressure on the anti-slip pad in real time. When a person or object steps on the anti-slip pad, the pressure sensor 2 senses the pressure change and converts it into an electrical signal. A signal line 4 connected to one side of the pressure sensor 2 is used to transmit the signal detected by the pressure sensor 2. The signal line 4 transmits the electrical signal generated by the pressure sensor 2 to subsequent data processing and analysis equipment, providing reliable data support for safety monitoring.

[0035] Waterproof partitions 11 installed inside the bottom plate 1 on both sides of the pressure sensor 2 effectively prevent moisture from seeping into the bottom plate 1, protecting the pressure sensor 2 and other electronic components from moisture and ensuring the long-term stable operation of the anti-slip pad. A water collection chamber 12 is located on the side of the waterproof partition 11 away from the pressure sensor 2, and a drain hole 13 is provided at the top of the water collection chamber 12. When moisture seeps into the anti-slip pad, it enters the water collection chamber 12 through the drain hole 13. A drain outlet is provided on one side of the water collection chamber 12, and a sealing plug 121 is installed at the drain outlet. When a certain amount of water accumulates in the water collection chamber 12, the sealing plug 121 can be opened to drain the water, facilitating water treatment and sealing maintenance, and ensuring the waterproof performance of the anti-slip pad.

[0036] The anti-slip layer 3 has notches on both sides at the bottom, and a sponge pad 31 is adhered inside the notches. The sponge pad 31 not only covers the perforation 13, maintaining the flatness of the anti-slip patch surface, but also has good water absorption. When water seeps into the anti-slip patch, the sponge pad 31 absorbs the water and guides it through the perforation 13 into the water collection tank 12, further improving the waterproof effect of the anti-slip patch.

[0037] A warning sign 32 is installed on the top side of the anti-slip layer 3. The warning sign 32 visually reminds people of the presence of the anti-slip sticker and its safe use, enhancing the product's practicality and safety. The bottom of the base plate 1 is coated with an adhesive layer. The base plate 1 is easily and firmly fixed to the ground by the adhesive layer, without the need for additional fasteners or tools, improving construction efficiency and the stability of the anti-slip sticker.

[0038] The anti-slip layer 3 is made of rubber, possessing good elasticity and wear resistance. Waterproof adhesive is used to fill the gaps between the bottom edge of the anti-slip layer 3 and the sponge pad 31. This waterproof adhesive effectively seals the gaps between the anti-slip layer 3 and the sponge pad 31, preventing moisture penetration and further enhancing the waterproof performance of the anti-slip pad. A waterproof layer is also fitted over the signal cable 4. This waterproof layer provides additional protection for the signal cable 4, preventing moisture from corroding and damaging it, and ensuring the stability and reliability of signal transmission.
