Description
TECHNICAL FIELD
[0001] The utility model relates to door and window section bar especially relates to a roll type timing carpet. BACKGROUND
[0002] In the current sports event timing system, the application of RFID technology mainly realizes data acquisition function through the timing carpet laid on the ground. The athletes need to wear disposable RFID electronic tags, when they pass through the timing carpet coverage area, the radio frequency identification module built-in the carpet will obtain the tag information in real time, and through wired / wireless transmission mode, the data is synchronized to the background timing control system, and after analysis and processing, the accurate event timing result is generated. Most of the timing carpets on the market are spliced carpets, each carpet is about 80cm-100cm long, and the carpets are spliced through joints. For the most widely used urban roads (such as marathon events) and standard tracks in sports venues (various track and field events), generally 6-8 meters of road surface need to be covered, and even 10 meters or more width need to be covered at the starting and finishing points of the marathon event. In order to obtain higher recognition rate, two carpets are generally laid at the same time, so that the number of carpets laid at each timing position is dozens to dozens, and the carpets need to be spliced manually. It takes 20-30 minutes to lay an average carpet. The recovery process is similar, each carpet needs to be disassembled and arranged, which consumes a lot of manpower and time, especially for marathon events, a regular marathon event often needs to lay ten such timing points, which consumes more time and manpower. For events with time limit requirements such as marathon or track and field, it is very important to save the arrangement time of timing equipment. However, the existing mainstream products mostly adopt split type splicing structure, which needs to connect and fix the carpet units manually, resulting in long time-consuming and long process of laying and recovering, and there are hidden dangers such as easy dislocation of joint and edge warping, which seriously restricts the deployment efficiency and use convenience in large-scale event scenarios.

[0018] The present application will be further described in detail below in combination with the drawings and specific embodiments.
[0019] Embodiment 1:
[0020] As Figure 1As shown, the present embodiment provides a roll type timing carpet, which comprises an upper granular rubber layer 1, a lower granular rubber layer 4, and a plurality of UHF RFID antennas 2 evenly spaced along the length direction in the middle layer. The feed line 6 of the antenna is drawn from the same side, which is convenient for quick connection with the timing control device. The antenna is filled with a foamed silica gel layer 3, which is sealed and adhered to the upper and lower rubber layers by environmentally friendly glue. The width range of the upper granular rubber layer 1 and the lower granular rubber layer 4 is 300-500 mm, and the length range is 2-10 m. In the present embodiment, the width of the upper and lower rubber layers is 400 mm, and the length is 8 meters. The filling thickness of the foamed silica gel layer 3 is in the range of 5-8 mm. In the present embodiment, the thickness of the foamed silica gel layer is 6 mm.
[0021] In the present embodiment, the integrated rubber layer and the foamed silica gel filling not only ensure flexibility, but also achieve sealing protection, avoiding the intrusion of moisture or dust. The unified feed line simplifies the connection steps and reduces the on-site debugging time. This structure can be directly rolled into a cylinder with a diameter of about 500 mm, occupying a small space for transportation and storage. When laid, it only needs to be rolled out. It takes 5 seconds to deploy a 6-meter length, significantly improving efficiency.
[0022] Embodiment 2:
[0023] Based on embodiment 1, the present embodiment adds a beveled body 5 to both sides of the carpet. The beveled edge 5a has an inclination angle of 35°, and the surface is provided with anti-slip particles. The beveled edge 5a of the beveled body 5 extends obliquely from the edge of the upper granular rubber layer 1 to the ground, the first right angle edge 5b of the beveled body is flush with the bottom surface of the lower granular rubber layer 4, and the second right angle edge 5c is aligned with the side edge of the carpet. The beveled body is made of soft silica gel material with the same thickness as the foamed silica gel layer.
[0024] In the present embodiment, the beveled body design makes the carpet edge smoothly transition to the ground, eliminating the risk of joint warping of traditional spliced carpets and avoiding tripping of athletes. The anti-slip particles enhance the friction between the beveled edge and the ground, ensuring that the carpet can still be closely attached to the concave and convex road surface. This design is particularly suitable for marathon tracks or uneven ground, with a safety improvement of more than 30%.
[0025] Embodiment 3:
[0026] The distance between the two adjacent UHF RFID antennas 2 is in the range of 0.5-1.5 m. In the present embodiment, the distance between the UHF RFID antennas 2 is set to 1.0 meter, the width of the upper and lower rubber layers is 350 mm, the length is 10 meters, and the thickness of the foamed silica gel layer is 5 mm. The antenna uses a PCB antenna with a side length of 140 mm, covering the frequency band of 860-960 MHz.
[0027] In this embodiment, the 1.0-meter antenna spacing takes into account the identification accuracy and cost, and is suitable for standard track and field race tracks and other scenarios. The 10-meter length meets the starting and finishing point coverage requirements of large-scale events, and the width of 350mm is convenient for uniform stress when rolling. The small size of the PCB antenna ensures that there is no damage when rolling, and the 5mm thick foamed silica gel provides sufficient cushioning and can withstand vehicle crushing without deformation.
[0028] Embodiment 4:
[0029] The overall thickness of this embodiment is optimized to 10mm, and the thickness of the upper and lower rubber layers is 2mm each. The thickness of the foamed silica gel layer is 6mm. The inclination angle of the inclined edge of the inclined edge body ranges from 30° to 45°. In this embodiment, the inclination angle of the inclined edge body is 45°, and the density of the surface anti-slip particles is increased by 20%.
[0030] In this embodiment, the ultra-thin design reduces the self-weight of the carpet, making it easy to roll up and operate by one person. The 45° inclined edge further reduces the height difference of the edge, and the dense arrangement of anti-slip particles enhances the grip in wet environments. This embodiment is particularly suitable for school physical fitness tests or short-distance races, and after laying, it is almost flush with the ground, reducing the interference with the athletes' gait.
[0031] The working principle of the roll-type timing carpet is that the timing control device supplies power to the UHF RFID antenna through the feeder, and the antenna radiates radio frequency signals to cover the carpet area. When the RFID chip worn by the athlete enters the coverage area, the antenna captures the chip information and transmits it to the background system, generating accurate timing data. The rolling mechanism is the synergistic effect of the soft particle material of the upper and lower rubber layers and the elasticity of the foamed silica gel, which allows the carpet to be rolled repeatedly without cracking. When rolling, the antenna has no stress concentration due to the small size design and uniform spacing arrangement, and the feeder is fixed along the side edge to avoid entanglement.
[0032] Compared with the traditional spliced carpet, the roll-type structure improves the laying efficiency by 4-5 times, shortens the recovery time to 1 / 4, prolongs the service life with integrated sealing design, and reduces the maintenance cost. The flexible material adapts to complex terrain, expanding the application scenarios.
[0033] In summary, the roll-type timing carpet disclosed in the present utility model has the following core advantages:
[0034] Efficient deployment and recovery, significantly saving labor and time cost, the roll-type structure allows the carpet to be rolled out directly like a normal carpet, and a 6-meter length only takes 5-6 seconds to lay, which is 4-5 times more efficient than the traditional spliced carpet (which takes 15-20 minutes). When recovering, it can be rolled up directly, and the 6-meter carpet takes only 2-3 minutes to recover, while the traditional method takes 8-10 minutes to disassemble and splice the units, which is more than 4 times more efficient. It is especially suitable for marathons and other events that require multiple timing points, greatly shortening the preparation time before the race and the cleaning time after the race.
[0035] Integrated sealing design, enhanced durability and environmental adaptability, upper and lower rubber and foamed silica gel layer are sealed by environmentally friendly adhesive, effectively blocking moisture and dust, prolonging the life of the antenna and internal components. The foamed silica gel layer (thickness 5-8mm) provides cushioning and can withstand vehicle crushing without damage, suitable for urban roads or mixed use sites. Soft granular rubber material allows the carpet to adhere to uneven ground, reducing the risk of warping and expanding the application scenarios to complex terrains such as off-road races and mountain races.
[0036] Safety optimization, reducing sports risks, the carpet is equipped with 30°-45° inclined edge on both sides, the surface contains anti-slip particles, eliminating the height difference of the edge to avoid tripping. The upper and lower rubber particle surfaces (front anti-slip, back grip) work together with the inclined edge anti-slip particles to ensure stability on wet or slippery surfaces, with safety improved by more than 30%.
[0037] Modular customization, flexible adaptation to diverse needs, carpet length supports 2-10 meter customization, width 300-500mm, meeting different event coverage needs (such as 10-meter long coverage for marathon start and finish). Antenna spacing optimization, UHF RFID antenna spacing 0.5-1.5m adjustable, balancing identification accuracy and cost, suitable for standard track and field tracks (1.0m spacing) or high-density identification scenarios (0.5m spacing). Ultra-thin and lightweight: overall thickness can be optimized to 10mm (2mm for each rubber layer, 6mm for foamed layer), reducing self-weight and facilitating single-person operation, rolling and transportation.
[0038] Economic and maintenance cost advantage, reducing labor dependence, no need for splicing and complex debugging, single person or small team can complete deployment, reducing labor costs. Long-life design, integrated structure reduces joint wear, sealed protection reduces component failure rate, maintenance cost is reduced by more than 50% compared with traditional spliced carpet.
[0039] The above embodiments are not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the technical solutions of the present application also belong to the protection scope of the present application.
