Description

Pipe leak detection device using RFID pad The present invention relates to a leak detection device, and more specifically, to a device that detects leaks in pipes without a separate power supply by utilizing a jacket equipped with passive RFID. Structures through which liquids, such as tap water and chemicals, flow are implemented in a wide variety of forms and applications. Leakage sensors are used to detect liquid leakage in such structures. Passive RFID leakage sensors, which do not require a separate power supply and fail to communicate properly when a leak occurs, are disclosed in Korean Registered Patent No. 10-1961537 and others. In actual field applications, it is difficult to supply power to RFID leakage sensors due to the complexity of the power supply structure. Accordingly, passive RFID leakage sensors that do not require a power supply are highly useful. Piping comes in a wide variety of shapes depending on the type. Specifically, pipe types include elbows, micro pipes, straight pipes, reducers, and tees, and are equipped with joints, flow meters, and pressure gauges. However, conventional RFID leak sensors have limitations in effectively mounting on pipes of various shapes while maintaining proper detection capabilities. FIG. 1 is a drawing illustrating an example of a detection system that detects a leak using a leak detection unit according to the present invention. Figure 2 is a drawing for explaining the leak detection unit of Figure 1. Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The embodiments described below may be modified in various different forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. In the drawings, exaggerated representations have been used for convenience of explanation. Meanwhile, terms indicating positions, such as top, bottom, front, etc., are related only to what is shown in the drawings. In practice, the sensing device can be used in any optional direction, and in actual use, the spatial direction changes depending on the direction and rotation of the sensing device. An embodiment of the present invention presents a pipe leak detection device that utilizes an RFID pad to effectively attach to various types of pipes while maintaining proper detection capabilities. To this end, the structure of the RFID pad will be examined in detail, and the process of verifying the presence of a pipe leak using the RFID pad will be explained in detail. The leak sensor according to an embodiment of the present invention detects the leakage of liquid in a structure through which liquids, such as tap water or chemicals, flow. Here, in order to maintain the internal temperature of the pipe at a specific temperature, the pipe is wrapped with a heater jacket in which a heating wire is embedded. FIG. 1 is a drawing for explaining an example of a detection system (100) that detects a leak using a leak detection unit (50) according to an embodiment of the present invention. However, it is not a drawing in the strict sense, and for convenience of explanation, there may be components not shown in the drawing. According to FIG. 1, the detection system (100) transmits detection information detected by the leak detection unit (50) to the control unit (102) via the collection antenna (101). The control unit (102) transmits the detection information to a wireless communication device (103), such as a mobile phone, or a wired communication device (104), such as a server. At this time, communication with the wireless communication device (103) may be carried out by the wired communication device (104) rather than the control unit (102). Here, although the collection antenna (101) and the control unit (102) are described as being connected via wired connection, the communication method in the detection system (100) can be varied in many ways within the scope of the present invention. For example, the collection antenna (101) and the control unit (102) may be connected wirelessly. The leak detection unit (50), which will be explained in detail later, checks for leaks in the piping (PL, see FIG. 2). At this time, the leak detection unit (50) includes an RFID pad (20), and the RFID antenna (23) on the RFID pad (20) is exposed to the outside. To ensure directionality, the externally exposed RFID antenna (23) can be positioned to face the collection antenna (101). It is preferable to exclude the placement of conductive materials, such as stainless steel, around the collection antenna (101) so as not to interfere with the collection of the detection information. FIG. 2 is a drawing for explaining the leak detection unit (50) of FIG. 1. At this time, the detection system (100) is to refer to FIG. 1. According to FIG. 2, the leak detection unit (50) includes an RFI
