Various mechanical equipment, such as semiconductor manufacturing equipment, is connected to the liquid piping to receive various liquids necessary for the process. Liquid piping is standardized to a given diameter, thickness and length. In accordance with the layout of the mechanical equipment, a plurality of liquid pipes are arranged at multiple locations in the working space where the mechanical equipment is installed. The plurality of liquid pipes are connected to each other by fittings (also referred to as'pipe connection portions') (see Patent Document 1).

If liquid leaks from the fittings while operating a machine, it can adversely affect the process. In addition, the liquid used in the process often contains components harmful to the environment. Therefore, it is important to quickly detect the liquid leaking from the fitting (referred to as'leakage').

Conventionally, after a long installation of a sensing sensor (also referred to as a'leak sensor') in the form of a film or wire at the bottom of a work space along a liquid pipe (hereinafter referred to as'piping'), the control circuit is A sensing sensor is wiredly connected to the built-in main body (also referred to as a'terminal'), and leaks leaked from the fittings are detected at the bottom of the work space and the results are confirmed in the main body.

In this case, it is difficult to install the detection sensor on the floor of the work space, avoiding the part where the mechanical equipment is installed. In addition, there is a complexity in that the sensing sensor and the main body must be wired to avoid the part where the mechanical equipment is installed. In addition, there is a waste of installing a sensing sensor to an unnecessary portion to cover the entire area where leakage of liquid is expected to fall. In addition, since the detection sensor is installed at the bottom of the work space and spaced apart from the fitting, there is a problem in that it is difficult to quickly detect a small amount of leakage with the detection sensor.

The technology underlying the present invention is published in the following patent documents.

Specifically, when the leaked liquid leaks from the gap between the pipe connecting portion 20 and its peripheral portion, the first detection member 210 can detect the leaked liquid. In addition, when the leaked liquid leaking from the gap between the pipe connecting portion 20 and its periphery flows along the outer circumferential surface of the pipe 10 due to viscosity, the second detection member 220 may detect the leaked liquid.

Diagnostic equipment according to an embodiment of the present invention, piping unit inspection devices respectively installed in a plurality of piping units, a repeater (not shown) capable of receiving a wireless signal output from the piping unit inspection devices, piping through the repeater It includes a terminal (not shown) that is connected to the sub-inspection devices in parallel and manages whether or not leakage occurs in a plurality of piping parts by giving a management number to the piping inspection devices.

Piping unit inspection devices may be installed together with the piping unit in a working space where the mechanical equipment is installed. Plumbing inspection devices may correspond to the number of piping. For example, if there are dozens of piping parts, the piping inspection devices may be provided in dozens, and may be installed in respective piping parts. The terminal may be provided in a predetermined space separated from the work space, for example, an office, and a repeater may be provided at a position to wirelessly connect the terminal and the pipe inspection devices.

The terminal can diagnose the leakage from the piping section in real time and output a diagnosis result. To this end, the terminal receives wireless signals, generates status information, and stores the status information for each management number, the output unit that receives status information from the storage unit and outputs it to the screen, and prioritizes a plurality of piping units. It may include, and may include a terminal control unit for controlling the output method of the output unit according to the priority.

The management number may be a set of numbers that can indicate the location of the piping portion, the type of liquid to be transported, and the type of connected mechanical equipment.

The storage unit may have a built-in diagnostic application and receive wireless signals from piping inspection devices to generate status information. For example, when a leak detection signal is output from a pipe inspection device, it may be input and store a management number and a leak detection state of the corresponding pipe section as a diagnostic history.

At this time, the output unit may group adjacent management numbers and output them together on the screen. Here, adjacent may mean that the positions of the piping portions are adjacent.

The terminal control unit may give priority to a plurality of piping units. The methods of prioritization may vary. For example, depending on the flow rate of the liquid, it is possible to give a relatively high priority to the piping for transferring a large amount of liquid. Alternatively, a relatively high priority may be given to a pipe part that transports a toxic liquid.

The terminal control unit may control the output method of the output unit variously so that when the leakage is simultaneously detected in the plurality of pipe units, the state information of the pipe unit having a high priority is highlighted.

It may further include a cartridge device (not shown) formed to be able to. The configuration of the cartridge device may vary. For example, the cartridge device is attached to a conveying sheet and a conveying sheet that is mounted in a predetermined position of the main body 100 and communicates with the piping part receiving space, is embedded in the cartridge body and is formed to pass through the piping part receiving space. It may include a detection member. At this time, a plurality of detection members are attached to the transport sheet, and a dummy member may be mounted between the detection members. The dummy member absorbs and removes liquid remaining in the piping accommodation space when the detection member is replaced. The transport sheet may be provided on the outer circumferential surface of the roller to be supplied to the piping section accommodating space in a roll-to-roll manner, or may be provided on the rail to be supplied to the piping section accommodating space in a slide manner.

In this case, after the initial leak is detected, the control unit of the piping inspection apparatus uses the cartridge device to quickly replace the detection member and waits until the next leak is detected. Then, when the next leak is detected, the leak rate of the leak may be calculated using the initial detection time of the leak and the next detection time, and transmitted to the terminal. The terminal may modify the priority of the piping portion so that the piping portion having a faster leak rate has a higher priority.

The above embodiments of the present invention are for the purpose of describing the present invention and not for the limitation of the present invention. It should be noted that the configurations and methods disclosed in the above embodiments of the present invention may be modified in various forms by combining or crossing each other, and such modified examples can be seen as the scope of the present invention. That is, the present invention will be implemented in a variety of different forms within the scope of the claims and equivalent technical spirit, and various embodiments are possible within the scope of the technical spirit of the present invention. Will be able to understand.
