Description

Technical Field

[0001] The utility model relates to the technical field of road identification, in particular to an RFID road stud. Background Art

[0002] With the rapid development of the automobile industry, vehicle warehouses, as important hubs connecting automobile manufacturers and dealers, have a direct impact on the smoothness of the entire automobile supply chain and customer satisfaction through their operational efficiency and management level. Compared with Western developed countries, my country's warehousing industry has shown some inherent characteristics in its development, such as large floor space, low degree of automation, and relatively backward software and hardware technology. Especially in the vehicle inventory process, the traditional warehousing management model is mainly manual operation, which is highly dependent on the experience and judgment of employees.

[0003] In the traditional vehicle warehouse management model, the vehicle inventory process is often carried out through manual input. This method can basically meet the needs when the workload is small, but once the workload surges, many problems will be exposed. For example, manual inventory is prone to increase error rate, decrease inventory accuracy, untimely information transmission and unclear responsibility definition. These problems not only increase the operating costs of enterprises, but also affect customers' trust in the reliability of the automotive supply chain.

[0004] Especially for warehouses with a long service life, the difficulty of inventory counting and the possibility of error are increased due to the fuzzy warehouse location lines and unclear warehouse location number identification. In this case, it is difficult to ensure the accuracy and reliability of inventory counting results by manual operation alone, and the inventory number often does not match the actual number of vehicles, which brings great trouble to the normal operation of the enterprise.

[0005] Therefore, an RFID road spike is proposed. Utility Model Content

[0037] Reference Figure 1 This specification provides an RFID road stud, comprising: an upper cover 1, an RFID middle piece 6, and a bottom cover 8, wherein the RFID middle piece 6 is fixed in the upper cover 1 through the bottom cover 8. The upper cover 1 is made of a new type of ABS reinforced resin material, which has the characteristics of high strength, pressure resistance, wear resistance, and non-deformation, and the material itself does not block the RFID signal and can avoid signal attenuation. The outer surface and four sides of the upper cover 1 are painted with wear-resistant reflective paint, which is effectively visible within 10 meters. The upper cover 1 has a hollow structure, which not only reduces the weight of the road stud, but also provides sufficient installation space for its internal components. The corners on multiple sides of the upper cover 1 are set as chamfers 5, which not only improves the aesthetics of the upper cover 1, but also enhances its structural strength and prevents damage or inconvenience during installation caused by sharp corners. The upper cover 1 is symmetrically provided with mounting holes 3 along an axis, and these mounting holes 3 are used to fix the RFID road stud on the road surface to ensure that it can remain stable under various weather and road conditions. The upper cover 1 is symmetrically provided with light guide holes 2 along another axis, and a visual window 4 is provided on one side of the upper cover 1 to facilitate daily inspection and maintenance.

[0038] Reference Figure 2, the RFID middleware 6 includes a pentahedral light-guiding RFID middleware 6, and the corners on multiple sides of the RFID middleware 6 are all set as chamfers 5, which not only improves the aesthetics of the RFID middleware 6, but also enhances its structural strength, and prevents damage or inconvenience during installation caused by sharp corners. The RFID middleware 6 is a hollow structure, and the RFID middleware 6 is provided with a raised light-guiding column 7 along the axis consistent with the upper cover 1. The design of the light-guiding column 7 is a key part of the cooperation between the middleware and the upper cover 1 and the bottom cover 8, ensuring the effective conduction of light and the stability of the overall structure. The upper raised portion of the light-guiding column 7 is tightly engaged with the light-guiding hole 2 of the upper cover 1, so that light can smoothly enter the light-guiding column 7 from the light-guiding hole 2, and then illuminate the visual window 4 inside the RFID middleware 6, enhancing visibility at night or in low-light environments. The lower raised portion of the light-guiding column 7 abuts against the bottom cover 8, which not only enhances the stability of the overall structure, but also prevents external factors such as dust and moisture from invading the internal components of the RFID middleware 6.

[0039] Reference Figure 3 The bottom cover 8 includes a rectangular bottom cover 8, which matches the size and shape of the bottom of the middle piece. The four sides of the bottom cover 8 are snap-fitted with the upper cover 1 and fixed by glue to ensure the stability and sealing of the overall structure, which not only simplifies the installation steps, but also improves the installation efficiency.

[0040] During installation, first put the RFID middleware 6 into the upper cover 1, engage the light guide column 7 with the light guide hole 2, and fix the bottom cover 8 with glue. Finally, fix the RFID road spike on the road surface through the mounting hole 3 of the upper cover 1. The entire installation process is simple and quick, without the need for complicated tools and steps, which greatly reduces the installation cost and time.

[0041] Reference Figure 4, the RFID middleware 6 has an RFID electronic tag built in, and the RFID electronic tag includes an analog radio frequency module Analog RF, a digital baseband module Digital control, and a storage module XLPM; the analog radio frequency unit Analog RF includes a matcher Matcher responsible for matching with the card reader Matcher to ensure stable signal transmission, a clock generating unit CLK providing a stable clock signal for the entire electronic tag, a reset unit Reset responsible for restoring the system to an initial state when an abnormality occurs in the system, a rectifier RECT that converts the received radio frequency signal into a DC power supply to provide power for the electronic tag, and a demodulator DEMOD and a modulator MOD that modulate the baseband signal generated by the digital baseband module Digital control into a radio frequency signal and sends it to the card reader Matcher; the demodulator DEMOD demodulates the signal sent by the card reader Matcher and transmits it to the digital baseband module Digital control; after the digital baseband module Digital control analyzes the signal sent by the card reader Matcher, it starts the internal state machine to execute commands one by one to complete the read, write, and erase operations on the storage module XLPM.

[0042] RFID electronic tags include KX2005XMP electronic tags, which comply with ISO / IEC 18000-6C (C1G2) protocol, have high reading sensitivity and multi-tag anti-collision performance, and can work stably in various harsh climates and complex working environments.

[0043] The outer surface of the upper cover 1 is provided with a QR code, which can be used to quickly identify the road spike information, perform equipment maintenance or interact with other smart devices.

[0044] The beneficial effects of the present invention are:

[0045] 1. The structure is simple and easy to install. The upper cover 1 and the bottom cover 8 are snapped together and fixed with glue, which increases the stability and durability of the device.

[0046] 2. The unique light-guiding design makes the connection between the RFID middleware 6 and the upper cover 1 and the bottom cover 8 tighter, while improving the efficiency of data transmission.
