[0021] The following specific embodiments, in conjunction with the accompanying drawings, illustrate the implementation of the connection component disclosed in this invention. Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. However, the following disclosure is not intended to limit the scope of protection of this invention. Without departing from the spirit of the invention, those skilled in the art can implement this invention in other different embodiments based on different viewpoints and applications. In the drawings, the thickness of layers, films, panels, regions, etc., is enlarged for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected" to another element, it may be directly on or connected to the other element, or an intermediate element may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected" to another element, no intermediate element is present. As used herein, "connection" can refer to physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" can refer to the presence of other elements between two elements.

[0022] It should be understood that although the terms "first," "second," "third," etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, "first element," "component," "region," "layer," or "part" discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of this document.

[0023] Furthermore, relative terms such as "below" or "bottom" and "above" or "top" may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the system beyond those shown in the figures. For example, if the system in a figure is flipped, an element described as being "below" the other elements will be oriented "above" the other elements. Thus, the exemplary term "below" can include both "below" and "above" orientations, depending on the specific orientation of the figure. Similarly, if the system in a figure is flipped, an element described as being "below" or "below" the other elements will be oriented "above" the other elements. Thus, the exemplary term "below" or "below" can include both "above" and "below" orientations.

[0024] As used herein, “about,” “approximately,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” or “substantially” herein may be chosen based on the optical, etched, or other properties to select a more acceptable range of deviations or standard deviations, and may not require a single standard deviation to apply to all properties.

[0025] The embodiments of the present invention will now be described with reference to Figures 1 to 6. This description is not intended to limit the embodiments of the present invention, but rather to provide one example of an embodiment of the present invention.

[0026] As shown in the embodiments of Figures 1, 2, and 4, the novel radio frequency identification (RFID) signal transmission detection device 100 is used in conjunction with a traffic vehicle glass G covered with a heat-insulating film. The RFID signal transmission detection device 100 includes an RFID analog tag 1 and an RFID reading device 2. The RFID analog tag 1 stores analog tag identification information. As shown in the embodiment of Figure 3, the RFID reading device 2 includes an RFID reader 21 and a signal sensing and prompting unit 22. The RFID reader 21 sends a detection and identification signal, and the RFID analog tag 1 generates a response signal in response to the detection and identification signal from the traffic vehicle glass G covered with the heat-insulating film. The signal sensing and prompting unit 22 is electrically connected to the RFID reader 21 and outputs a normal transmission indication signal in response to the RFID reader 21 receiving the response signal from the traffic vehicle glass G covered with the heat-insulating film.

[0027] Furthermore, as shown in Figures 1, 2 and 4, a radio frequency identification signal transmission detection device 100 according to an embodiment of the present invention is used to detect whether a vehicle glass G with a heat insulation film attached blocks the transmission of radio frequency identification (RFID) signals.

[0028] As shown in Figures 1, 2 and 4, the radio frequency identification signal transmission detection device 100 includes: a radio frequency identification analog tag 1 and a radio frequency identification interpretation device 2.

[0029] In detail, the radio frequency identification analog tag 1 stores analog tag identification information to simulate the vehicle identification information of a specific vehicle as an Electronic Toll Collection (ETC) tag.

[0030] Specifically, according to an embodiment of the present invention, a radio frequency identification signal transmission detection device 100 is provided, wherein the radio frequency identification analog tag 1 is a passive radio frequency identification tag.

[0031] As shown in Figures 2 and 4, according to an embodiment of the present invention, a radio frequency identification (RFID) signal transmission detection device 100 has an adhesive surface for the RFID analog tag 1, which is reusable and removable, provided with a glass adhesive layer 11. The glass adhesive layer 11 is adhered to a vehicle glass G covered with a heat-insulating film, allowing the RFID analog tag 1 to be repeatedly applied and removed from the vehicle glass G. This allows the RFID signal transmission detection device 100 to repeatedly detect whether the vehicle glass covered with the heat-insulating film obstructs the transmission of RFID signals on multiple vehicles.

[0032] As shown in Figures 3 to 5 and Figure 6, the radio frequency identification (RFID) reading device 2 has an RFID reader 21 and a signal sensing and prompting unit 22 electrically connected to the RFID reader 21.

[0033] As shown in Figures 3 to 5 and Figure 6, a radio frequency identification (RFID) signal transmission detection device 100 according to an embodiment of the present invention includes an RFID reading device 2 with a portable housing 20. An RFID reader 21 and a signal sensing and prompting unit 22 are encapsulated within the portable housing 20.

[0034] As shown in Figures 3 to 5, in the specific embodiments disclosed in this invention, the radio frequency identification reader 21 and the radio frequency identification analog tag 1 are arranged in a manner that is spaced apart by a preset radio frequency identification distance and that their signal transmissions correspond to each other. A penetrating medium setting space is formed between the radio frequency identification reader 21 and the radio frequency identification analog tag 1 for setting the vehicle glass G with heat insulation film attached.

[0035] As shown in Figures 3 to 5 and Figure 6, the signal sensing and prompting unit 22 outputs a normal transmission indication signal based on the response signal received by the RFID reader 21 from the RFID analog tag 1. Specifically, the response signal is generated by the RFID analog tag 1 corresponding to the detection and identification signal sent by the RFID reader 21 and transmitted back to the RFID reader 21. The response signal is transmitted through the vehicle glass G, which is covered with a heat-insulating film.

[0036] In other words, this new invention, by placing a vehicle glass G with heat insulation film attached in the space of the penetrating medium, detects and confirms that the vehicle glass G with heat insulation film attached does not block the transmission of radio frequency identification (RFID) signals based on the output of the normal transmission indication signal.

[0037] Furthermore, in an embodiment of the present invention, the radio frequency identification signal transmission detection device 100 outputs a transmission abnormality indication signal when the radio frequency identification reader 21 does not receive a response signal from the radio frequency identification analog tag 1.

[0038] More specifically, in the embodiment shown in FIG5, the signal sensing prompt unit 22 includes an indicator light 220. The signal sensing prompt unit 22 emits a green light according to the normal transmission indication signal and emits a red light according to the abnormal transmission indication signal.

[0039] As shown in Figures 3 to 5 and 6, in an embodiment of the present invention, a radio frequency identification signal transmission detection device 100 includes a signal sensing prompting unit 22 further comprising a display screen 221. The display screen 221 is configured to display analog tag identification information included in the response signal of the radio frequency identification analog tag 1.

[0040] As shown in Figure 3, an RFID signal transmission detection device 100 according to an embodiment of the present invention includes an RFID reading device 2 having a battery unit 23. The battery unit 23 is detachably mounted on the RFID reading device 2. The battery unit 23 is configured to provide operating power to the RFID reader 21 and the signal sensing prompt unit 22.

[0041] As shown in Figures 3 and 4, according to an embodiment of the present invention, a radio frequency identification (RFID) signal transmission detection device 100 further includes an RFID reading device 2 with a control unit 24. The control unit 24 is electrically connected to the RFID reader 21 and the signal sensing prompting unit 22. The control unit 24 selects a detection signal with a predetermined output power suitable for a vehicle glass G with a heat-insulating film, based on the following: the RFID reader 21 sends a plurality of detection and identification signals with a predetermined output power, and a plurality of response signals are transmitted back to the RFID reader 21 by the RFID analog tag 1 within a predetermined signal sensing waiting time.

[0042] As shown in Figures 3, 5, and 6, an embodiment of the radio frequency identification (RFID) signal transmission detection device 100 according to the present invention includes an RFID reading device 2 further comprising an information transmission port 25. The information transmission port 25 is electrically connected to the control unit 24, the RFID reader 21, and the signal sensing and prompting unit 22. Furthermore, the information transmission port 25 is configured for communication connection to an external information processing device.

[0043] As described above, the novel radio frequency identification (RFID) signal transmission detection device 100, by placing a vehicle glass G with a heat-insulating film attached in the transmission medium space (located between the RFID reader 21 and the RFID analog tag 1), and by detecting and confirming that the vehicle glass G with the heat-insulating film does not obstruct the transmission of RFID signals based on the normal transmission indication signal from the signal sensing and prompting unit 22, can output a green light. Conversely, if the RFID reader 21 does not receive a response signal from the RFID analog tag 1, the signal sensing and prompting unit 22 outputs a transmission abnormality indication signal and can output a red light.

[0044] Furthermore, this novel device, by providing a reusable and removable glass adhesive layer 11 on the adhesive surface of the RFID analog tag 1, allows the RFID analog tag 1 to be repeatedly applied and removed onto the vehicle glass G covered with heat-insulating film. Therefore, the RFID signal transmission detection device 100 of this novel device can be applied to a wide variety of vehicles to repeatedly detect whether the vehicle glass covered with heat-insulating film obstructs the transmission of RFID signals.

[0045] Furthermore, this novel device displays analog tag identification information encompassed by the response signal from the radio frequency identification analog tag 1 via the display screen 221 of the signal sensing prompt unit 22.

[0046] On the other hand, in this novel radio frequency identification signal transmission detection device 100, the radio frequency identification reading device 2 further has an information transmission port 25, which allows the radio frequency identification reading device 2 to communicate with an external information processing device to perform subsequent information processing operations related to the radio frequency identification analog tag 1 (or electronic toll system tag).

[0047] This invention has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this invention. It must be noted that the disclosed embodiments do not limit the scope of this invention. Conversely, modifications and equivalent arrangements within the spirit and scope of the claims are included within the scope of this invention.
