Description

IoT-based safety diagnosis and risk prediction sensor device for multi-use energy facilities

[0001] The present invention relates to an IoT-based safety diagnosis and risk prediction sensor device for multi-use energy facilities, and more specifically, to an IoT-based safety diagnosis and risk prediction sensor device for multi-use energy facilities that is portable or movable and can be installed anywhere within industrial facilities using high-risk gases such as hydrogen to conduct gas leak and safety diagnosis in real time.

[0002]

[0003] There is a high risk of explosion accidents at high-risk gas facilities caused by defects in the on-site system itself.

[0004] Therefore, in order to prevent damage to gas facilities caused by such explosion accidents, only products that have obtained explosion-proof certification in accordance with the High Pressure Gas Act are required to be installed at these sites.

[0005] In industrial sites where toxic gases, including carbon monoxide, that can lead to death by suffocation upon inhalation are used, poisoning accidents frequently occur during processes and maintenance.

[0006] As gas leak accidents at such high-risk gas facilities occur frequently, causing massive economic and human losses, there is an urgent need to develop a smart safety management system capable of initial response by facility or zone.

[0007]

[0008] The present invention was developed to improve upon the aforementioned problems and aims to provide an Internet of Things-based safety diagnosis and risk prediction sensor device for multi-use energy facilities that is portable or movable within industrial facilities using high-risk gases such as hydrogen, and can be installed anywhere to conduct real-time gas leak and safety diagnoses.

[0009]

[0010] To achieve the above objectives, the present invention may provide an IoT-based safety diagnosis and risk prediction sensor device for a multi-use energy facility, characterized by comprising: a base detachably attached to a structure inside a multi-use energy facility; a communication module embedded with an IoT-based PCB provided on the base and capable of communicating with a control center and server of the facility; and a sensor module provided on the base for measuring gas concentration inside the facility.

[0011] Herein, the invention is characterized by further including a warning module that is provided on the base and electrically connected to the communication module and the sensor module, and detects when the gas concentration detected by the sensor module deviates from a normal range preset to the control center and the server, thereby notifying in real time that there is an emergency situation including a gas leak or fire.

[0012] At this time, the communication module is characterized by comprising: a first casing formed on the upper surface of the base and housing the PCB; an antenna provided on one side of the first casing, electrically connected to the PCB and capable of communicating with the control center and the server; and a transmitter provided on one side of the first casing, which outputs the level of vibration, temperature, humidity, or noise inside the facility in real time.

[0013] In addition, the communication module further comprises a pivot elbow provided between the first casing and the tip of the antenna, which rotatably connects the antenna to the first casing.

[0014] In addition, the sensor module comprises a second casing provided on the upper surface of the base, a cover detachably coupled to the open front of the second casing to close the open front, a gasket provided between the open front of the second casing and the cover, and a plurality of gas sensors embedded in the second casing and electrically connected to the PCB embedded in the first casing of the communication module provided on the upper surface of the base.

[0015] Additionally, the sensor module further comprises a connecting bolt body protruding from the side of the second casing and having male threads formed along its outer surface so as to be screw-coupled to a connecting port provided on the side of the first casing, and a sealing nut coupled to the outer surface of the connecting bolt body to prevent the connecting bolt body from being screw-separated from the connecting port.

[0016] In addition, it is characterized by further including an installation module comprising a mounting groove to which the base is fixed and a clamp to which the structure is detachably fixed.

[0017]

[0018] According to the present invention with the above-described configuration, the following effects can be achieved.

[0019] First, the present invention has the distinct advantage of being portable or movable within industrial facilities using high-risk gases such as hydrogen, and being able to install it anywhere to conduct real-time gas leak and safety inspections, thereby ensuring the safety of workers from suffocation accidents and enabling the prevention of explosion and fire accidents caused by gas leaks and a rapid response.

[0020] In particular, the present invention is highly efficient in that it enables continuous monitoring of high-risk facilities and equipment at an efficient cost over large areas of city gas, petrochemical, and gas plants managed under the three gas laws.

[0051] That is, the batteries (710) inside the explosion-proof enclosure (700) are arranged in parallel to supply power to the communication module (200), sensor module (300), and warning module (500) described later in stages, so that power can be supplied for a period of, for example, about 6 months per battery (710) and the remaining batteries (710) can supply power for an additional period, so that there is no disruption in power supply for a long period even without receiving power from the outside.

[0076] Additionally, the clamp (602) may include a first clamping tooth (661) having a repeating pattern of protruding peaks and recessed grooves along the inner surface of the lower part of the first clamp bar (660), and a second clamping tooth (671) having a repeating pattern of protruding peaks and recessed grooves along the inner surface of the lower part of the second clamp bar (670).

[0077] Additionally, the clamp (602) may include a first contact pad (662) that is fixed to a first clamp bar (660) to cover a first clamping tooth (661) and contacts the outer surface of the structure (400), and a second contact pad (672) that is fixed to a second clamp bar (670) to cover a second clamping tooth (671) and contacts the outer surface of the structure (400).

[0078]

[0079] Meanwhile, if the structure (400) is a solid or hollow column as shown in FIG. 4, the first and second clamp bars (660, 670) of a fixed structure can be used, but if the structure (400) has a cross-section formed in the shape of an “H” or “I” as shown in FIG. 5, it is preferable for the clamp (602) to be equipped with a rotational structure as follows.
