Description

Technology Field

[0001] The present invention relates to a system for managing a detachable portable gas detector, and more specifically, to a system for managing a detachable portable gas detector in which a main unit for processing gas detection data and a gas detection unit for detecting gas are manufactured separately so that they can be used as a detachable unit, and the gas detection unit is manufactured differently depending on the type of gas detection so that the type of gas detection of the portable gas detector can be freely changed. Background Technology

[0002] Generally, a portable gas detector is a device that prevents safety accidents by detecting gas leaks in advance, and it is a device that can detect gas leaks while being conveniently carried around.

[0003] Portable gas detectors offer the advantage of making inspections much easier than detecting gas leaks by soap bubbles or gas odors, and are used to conveniently detect gas leaks from gas appliances such as piping in gas-powered vehicles and automotive LPG storage systems, gas piping in homes or factories, and gas equipment such as heaters, boilers, or gas stoves.

[0004] These portable gas detectors are devices that detect five gases (oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), flammable gas (EX), and carbon dioxide (CO2)) as defined by the Industrial Safety and Health Act.

[0005] Depending on the industrial site (e.g., chemical complex) or factory facilities, only a few specific gases among the above five gases may be detected. To prepare for such cases, portable gas detectors are manufactured in various forms according to the type of gas. This results in the inconvenience of having to manufacture portable gas detectors separately depending on the type of gas to be detected, and also has the disadvantage of high manufacturing costs.

[0006] In addition, the gas detection sensor installed in the portable gas detector has a fixed lifespan, which may vary depending on usage time, and requires periodic calibration.

[0007] For calibration, the portable gas detector is delivered to a calibration company (or institution), or the calibration company transports equipment with a built-in calibration program to the company using the portable gas detector to perform on-site calibration and calibrate the gas detection sensor.

[0008] Consequently, this results in the disadvantage that calibrating portable gas detectors is inconvenient and requires a long time.

[0009] Therefore, there is a need for technology that facilitates the manufacturing of portable gas detectors, enables real-time calibration, automatically determines the sensor's lifespan, and notifies the user of the sensor replacement cycle, thereby ensuring precise gas detection at all times.

Specific details for implementing the invention

[0045] A detachable portable gas detector and a system for managing the same according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0046] The terms or words used in the present invention described below should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0047] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all technical concepts of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0048] FIG. 1 is a configuration diagram of a detachable portable gas detector according to a preferred embodiment of the present invention, FIG. 3 is a block diagram showing an embodiment of a detachable portable gas detector, and FIG. 5a to 5d are examples of using a gas detection part of a detachable portable gas detector in the present invention by replacing it according to the type of sensor.

[0049] The detachable portable gas detector (100) according to the present invention is divided into a main module (110) and a gas detection unit (120).

[0050] The main module (110) processes gas detection data and transmits the processed gas detection data to a remote monitoring server (500).

[0051] The gas detection unit (120) is detachably coupled to or separated from the main module (110) and serves to detect a target gas using gas detection sensors (121, 122).

[0052] The gas detection unit (120) may be variably equipped with gas detection sensors (121, 122) depending on the type of gas to be detected.

[0053] Preferably, the main module (110) may include a GPS module (111) for acquiring location information, a power supply unit (115) for supplying power, a function selection unit (114) for selecting a gas detection function, a control unit (117) for processing gas detection data detected by the gas detection unit (120) based on the gas detection function selected by the function selection unit (114) and storing it in a storage unit (116), controlling the transmission of the stored gas detection data through a communication unit (112), and controlling the transmission of status information of the gas detection unit (120), and a display unit (113) for displaying sensor replacement alarm information generated by the control unit (117) on a screen.

[0054] Preferably, when the control unit (117) receives calibration data for calibrating the gas detection sensor (121, 122), it calibrates the gas detection sensor or corrects the detection data of the gas detection sensor based on the calibration data, and when it receives sensor replacement data, it may generate an alarm for sensor replacement.

[0055] The operation of the detachable portable gas detector (100) configured in this way is specifically described as follows.

[0056] First, the user detecting the gas selects one of the gas detection units (120, 130, 140) according to the type of gas to be detected and mounts it on the main module (110) as shown in FIG. 5a.

[0057] The types of gases to be detected here include the five gases prescribed by the Industrial Safety and Health Act (oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), flammable gas (EX), and carbon dioxide (CO2), and up to six gases can be detected by detecting additional gases to be detected.

[0058] FIG. 5b is an example of using a gas detection unit (120) equipped with two gas detection sensors (121, 122) on a main module (110), FIG. 5c is an example of using a gas detection unit (130) equipped with four gas detection sensors (131, 132, 133, 134) on a main module (110), and FIG. 5d is an example of using a gas detection unit (140) equipped with six gas detection sensors (141, 142, 143, 144, 145, 146) on a main module (110).

[0059] As such, the present invention has the advantage of preventing the inconvenience of individually manufacturing gas detectors for each type of gas and the waste of manufacturing costs by manufacturing the gas detection unit (120, 130, 140) in the form of a module equipped with an appropriate gas detection sensor according to the type of gas, and selectively mounting it on the main module (110) through a mounting part according to the type of gas to be detected. In particular, in the past, companies felt burdened by the cost of purchasing gas detectors because multiple portable gas detectors for each type of gas had to be provided to detect various gases; however, if the gas detection unit is used as a replaceable type according to the type of gas as in the present invention, the cost of purchasing portable gas detectors can be reduced.

[0060] In the present invention, as an example of an embodiment, a gas detection unit (120) equipped with two gas detection sensors (121, 122) as shown in FIG. 5b is to be described as being used by mounting it on the main module (110), but it is not limited to this, and it will be obvious to a person with ordinary knowledge in the art that a gas detection unit (130) equipped with four gas detection sensors (131-134) as shown in FIG. 5c, or a gas detection unit (140) equipped with six gas detection sensors (141-146) as shown in FIG. 5d, can be used by mounting it.

[0061] When a gas detection unit (120) is mounted on the main module (110), data and power supply are provided to both ends in the form of a connector.

[0062] Subsequently, when the user operates the power button of the power unit (115) to the ON state to supply power for operation to the detachable portable gas detector (100), the control unit (117) performs initialization and then acquires sensor information transmitted from the gas detection unit (120) and stores it in the storage unit (116). Here, the sensor information may include usage information of the sensor and registration information for registering the sensor. To this end, it is assumed that the gas detection unit (120) is equipped with a sensor status detection function capable of internally storing sensor information, counting and storing sensor usage time information, and detecting sensor status information.

[0063] Afterward, when the user selects the gas detection function through the function selection unit (114), the control unit (117) performs the gas detection operation through the gas detection unit (120) and obtains location information and time information through the GPS module (111).

[0064] The gas detection unit (120) detects the gas to be measured and the gas concentration using the installed gas detection sensors (121) (122), converts this into gas detection data, and transmits it to the main module (110) through the connector.

[0065] The control unit (117) of the main module (110) receives gas detection data through the data receiving unit, maps the received gas detection data with location information, and stores it in the storage unit (116).

[0066] Next, gas detection data is displayed through an indicator (113) so that the user can recognize the gas status at the corresponding location, and additionally, gas detection data stored in the storage unit (116) is transmitted to the monitoring server side through the communication unit (112) according to the transmission cycle of the gas detection data or the user's transmission command.

[0067] The monitoring server collects gas detection data remotely and stores it in a database for analysis, enabling administrators to monitor the status of gas detection.

[0068] FIG. 2 is a configuration diagram of a system for managing a detachable portable gas detector (100) as described above, and may include a detachable portable gas detector (100), a gateway (200), a wireless data collector (300), a monitoring server (500), and a sensor management server (400).

[0069] A detachable portable gas detector (100) includes a main module (110) that processes gas detection data and transmits the processed gas detection data to a remote monitoring server (500), and a gas detection unit (120) that is detachably coupled to or separated from the main module (110) and detects a target gas using a gas detection sensor, and can be carried and moved by a user and performs the function of detecting gas at a desired location.

[0070] The configuration of this detachable portable gas detector (100) is the same as the configuration of FIG. 3, and its operation is also the same.

[0071] However, when the control unit (117) receives calibration data for calibrating the gas detection sensors (121, 122), it calibrates the gas detection sensors based on the calibration data or corrects the detection data of the gas detection sensors, and when sensor replacement data is received, it generates an alarm for sensor replacement and displays it through the indicator (113).

[0072] The gateway (200) relays gas detection data and gas sensor status information transmitted from the detachable portable gas detector (100), and transmits calibration data and alarm data for sensor replacement to the detachable portable gas detector (100). This gateway (200) can be described as a relay device that relays data.

[0073] The wireless data collector (300) separates the gas detection data and gas sensor data received from the gateway (200), transmits the separated gas sensor data to the sensor management server (400), and transmits the separated gas detection data to the monitoring server (500).

[0074] The monitoring server (500) plays the role of monitoring gas detection data transmitted from the wireless data collector (300).

[0075] The sensor management server (400) extracts sensor information based on gas sensor data transmitted from the wireless data collector (300) and registers it in a database, processes the sensor data to generate calibration data and transmits it to the wireless data collector (300), and generates alarm data for sensor replacement and transmits it to the wireless data collector (300).

[0076] Preferably, the sensor management server (400) may include, as illustrated in FIG. 4, a sensor registration unit (401) that extracts sensor information based on gas sensor data transmitted from the wireless data collector (300) and registers it in a database (410), a sensor data collection unit (402) that collects the gas sensor data, a sensor data processing unit (403) that processes the sensor data collected by the sensor data collection unit (402), and a calibration data generation unit (404) that performs calibration using a calibration program stored in the database based on the processed sensor data and generates calibration data based on the calibration results.

[0077] Additionally, the sensor management server (400) may include a sensor replacement data generation unit (405) that determines whether a sensor needs to be replaced based on sensor information registered in the database (410) and generates sensor replacement data when a sensor replacement is due; an alarm generation unit (406) that generates alarm data based on the sensor replacement data generated by the sensor replacement data generation unit (405); and a communication unit (407) that transmits the calibration data and alarm data to a wireless data collector (300).

[0078] The operation of the system for managing a detachable portable gas detector according to a preferred embodiment of the present invention configured as described above is specifically explained as follows.

[0079] First, the user detecting the gas selects one of the various gas detection units (120, 130, 140) according to the type of gas to be detected, as shown in FIG. 5b to 5d, and mounts it on the main module (110) as shown in FIG. 5a.

[0080] The types of gases to be detected here include the five gases prescribed by the Industrial Safety and Health Act (oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), flammable gas (EX), and carbon dioxide (CO2), and up to six gases can be detected by detecting additional gases to be detected.

[0081] FIG. 5b is an example of using a gas detection unit (120) equipped with two gas detection sensors (121, 122) on a main module (110), FIG. 5c is an example of using a gas detection unit (130) equipped with four gas detection sensors (131, 132, 133, 134) on a main module (110), and FIG. 5d is an example of using a gas detection unit (140) equipped with six gas detection sensors (141, 142, 143, 144, 145, 146) on a main module (110).

[0082] As such, the present invention has the advantage of preventing the inconvenience of individually manufacturing gas detectors for each type of gas and the waste of manufacturing costs by manufacturing the gas detection unit (120, 130, 140) in the form of a module equipped with an appropriate gas detection sensor according to the type of gas, and selectively mounting it on the main module (110) through a mounting part according to the type of gas to be detected. In particular, in the past, companies felt burdened by the cost of purchasing gas detectors because multiple portable gas detectors for each type of gas had to be provided to detect various gases; however, if the gas detection unit is used as a replaceable type according to the type of gas as in the present invention, the cost of purchasing portable gas detectors can be reduced.

[0083] In the present invention, as an example of an embodiment, a gas detection unit (120) equipped with two gas detection sensors (121, 122) as shown in FIG. 5b is to be described as being used by mounting it on the main module (110), but it is not limited to this, and it will be obvious to a person with ordinary knowledge in the art that a gas detection unit (130) equipped with four gas detection sensors (131-134) as shown in FIG. 5c, or a gas detection unit (140) equipped with six gas detection sensors (141-146) as shown in FIG. 5d, can be used by mounting it.

[0084] When a gas detection unit (120) is mounted on the main module (110), data and power supply are provided to both ends in the form of a connector.

[0085] Subsequently, when the user turns the power button of the power unit (115) to the ON state to supply power for operation to the detachable portable gas detector (100), the control unit (117) performs initialization and then acquires sensor information transmitted from the gas detection unit (120) and stores it in the storage unit (116). Here, the sensor information may include usage information of the sensor and registration information for registering the sensor. To this end, it is assumed that the gas detection unit (120) is equipped with a sensor status detection function capable of internally storing sensor information, counting and storing sensor usage time information, and detecting sensor status information.

[0086] Afterward, when the user selects the gas detection function through the function selection unit (114), the control unit (117) performs the gas detection operation through the gas detection unit (120) and obtains location information and time information through the GPS module (111).

[0087] The gas detection unit (120) detects the gas to be measured and the gas concentration using the installed gas detection sensors (121) (122), converts this into gas detection data, and transmits it to the main module (110) through the connector.

[0088] The control unit (117) of the main module (110) receives gas detection data through the data receiving unit, maps the received gas detection data with location information, and stores it in the storage unit (116).

[0089] Next, gas detection data is displayed through an indicator (113) so that the user can recognize the gas status at the corresponding location, and additionally, gas detection data stored in the storage unit (116) is transmitted to the monitoring server side through the communication unit (112) according to the transmission cycle of the gas detection data or the user's transmission command. Here, the gas detection data may include gas detection data, gas sensor registration data, and gas sensor data. In the case of a gas sensor being used for the first time, the gas sensor registration data is used to determine the lifespan of the gas sensor by considering the usage time, and the gas sensor data may include the usage time and status information of the gas sensor.

[0090] The gateway (200) relays gas detection data transmitted from the detachable portable gas detector (100) to the wireless data collector (300).

[0091] The above wireless data collector (300) separates the gas detection data received from the gateway (200) into gas sensor registration data and gas sensor data, transmits the separated gas sensor registration data and gas sensor data to the sensor management server (400), and transmits the separated gas detection data to the monitoring server (500).

[0092] The monitoring server (500) collects gas detection data remotely and stores it in a database so that it can be analyzed, allowing an administrator to monitor the status of gas detection.

[0093] In addition, the sensor management server (400) registers the gas sensor information in the database (410) based on the gas sensor registration data through the sensor registration unit (401).

[0094] Here, since the gas sensor registration data includes identification information that can distinguish the gas sensor, the corresponding gas sensor is registered in the database (410) based on this. Once the gas sensor is registered, its lifespan is managed based on the time of registration.

[0095] In addition, the sensor data collection unit (402) collects gas sensor data transmitted from the wireless data collector (300) and transmits it to the sensor data processing unit (403).

[0096] The sensor data processing unit (403) processes the sensor data collected by the sensor data collection unit (402) and stores the processed sensor data in the database (410). Here, sensor data processing refers to functions such as separating sensor status data and sensor usage time information included in the sensor data.

[0097] These sensor data are periodically acquired while the detachable portable gas detector (100) is in operation and can be accumulated and stored in a database (410) based on sensor identification information.

[0098] When the sensor data is registered in the database (410), the calibration data generation unit (404) analyzes the sensor status data using a calibration program stored in the database (410) to perform calibration, generates calibration data based on the calibration results, and transmits it to the wireless data collector (300) through the communication unit (407).

[0099] Conventional sensor calibration for gas detectors involves moving equipment equipped with a calibration program to the site to calibrate the portable gas detector sensor, or moving the portable gas detector to a location where equipment storing the calibration program is stored to calibrate the sensor. This method has the disadvantages of being not only complex but also lacking real-time capability and requiring a significant amount of time.

[0100] To solve this, the present invention transmits only the gas sensor status data to the sensor management server (400) via a network, and the sensor management server (400) automatically generates calibration data using a calibration program and transmits the calibration data to the detachable portable gas detector (100) in real time via the network, thereby enabling the gas sensor to be calibrated, which not only facilitates the calibration of the gas sensor but also enables the gas sensor to be calibrated in real time.

[0101] That is, the wireless data collector (300) transmits calibration data received from the sensor management server (400) to the detachable portable gas detector (100) through the gateway (200).

[0102] The communication unit (112) of the above-mentioned detachable portable gas detector (100) receives this and transmits it to the control unit (117).

[0103] The control unit (117) stores the received data in the storage unit (116) if it is sensor calibration data, and transmits the calibration data to the gas detection unit (120) at a time when the gas detection unit (120) does not detect gas.

[0104] The above gas detection unit (120) automatically calibrates the gas detection sensor by adjusting the sensitivity, etc. of the gas detection sensor based on the transmitted calibration data.

[0105] Another method for calibrating the gas detection sensor is to receive calibration data from the control unit (117) and store it in the storage unit (116), and when gas detection data is transmitted from the gas detection unit (120), the gas detection data is automatically calibrated based on the calibration data, and then the calibrated gas detection data is stored in the storage unit (116). Calibration means correcting the detection value of the gas detection data by compensating it with the calibration value included in the calibration data. The accuracy of the actual gas detection sensor decreases with continued use compared to when it was first used. Therefore, to prevent such a decrease in accuracy, it is necessary to calibrate the sensor, and this is done based on calibration data through a network.

[0106] Meanwhile, the sensor replacement data generation unit (405) of the sensor management server (400) determines whether the sensor needs to be replaced based on the sensor information registered in the database (410), and when the sensor replacement is due, generates sensor replacement data and transmits it to the alarm generation unit (406).

[0107] Here, gas detection sensors have a defined lifespan depending on the type of sensor. If used after their designated lifespan has elapsed, it may be difficult to accurately detect gas even after calibration. In such cases, it is advisable to replace the gas detection sensor.

[0108] Accordingly, the sensor replacement data generation unit (405) determines the time for sensor replacement based on the usage time, calibration cycle, and number of calibrations of the corresponding gas detection sensor registered in the database (410). Here, when determining the time for sensor replacement, the highest weight is given to the usage time of the gas detection sensor, and the calibration cycle and number of calibrations are given lower weights compared to the usage time, so that the usage time is given significant consideration in determining the time for gas detection sensor replacement.

[0109] When sensor replacement data is generated in this way, the alarm generation unit (406) generates alarm data based on the generated sensor replacement data and transmits it to the communication unit (407).

[0110] Here, the alarm data may include sensor replacement data and identification information of the corresponding sensor.

[0111] The above communication unit (407) transmits the alarm data generated by the alarm generation unit (406) to the wireless data collector (300) through a set communication method.

[0112] The above wireless data collector (300) transmits the received alarm data to the detachable portable gas detector (100) through the gateway (200).

[0113] The communication unit (112) of the above-mentioned detachable portable gas detector (100) transmits alarm data to the control unit (117) when it receives it.

[0114] The above control unit (117) stores the transmitted alarm data in the storage unit (116) and displays the alarm data through the indicator (113).

[0115] The alarm data displayed here may be gas sensor identification information and sensor replacement timing information. The sensor replacement timing information may indicate how much usage is required before replacing the sensor.

[0116] Therefore, a user of the detachable portable gas detector (100) checks the alarm data displayed on the indicator (113) and replaces the gas detection sensor at the time of sensor replacement to maintain continuous gas detection.

[0117] In other words, since users cannot determine the replacement time for the gas detection sensor, the conventional method involves replacing the sensor if it fails to detect gas during operation, assuming it has malfunctioned or reached the end of its lifespan. In this case, a problem occurs during the gas detection process; because the sensor cannot be replaced in real-time on-site unless it is carried separately at all times, a problem arises where the gas detection operation stops.

[0118] To solve this problem, the present invention monitors a gas sensor in real time based on the status data and registration information of the gas sensor, and automatically notifies the user when the time for replacing the gas detection sensor is approaching, thereby enabling the user to replace the gas detection sensor in advance before a sudden failure occurs, thus ensuring continuity in gas detection.

[0119] According to the present invention described above, convenience in using a gas detector is provided by manufacturing a main unit that processes gas detection data and a gas detection unit that detects gas separately, and making them detachable. Additionally, by manufacturing the gas detection unit differently depending on the type of gas detection, the type of gas detection of the portable gas detector can be freely changed and used.

[0120] In addition, according to the present invention, the status of the gas detection sensor of a portable gas detector is analyzed in real time through a network to generate calibration information, and calibration of the gas detection sensor can be performed remotely through the network, thereby providing convenience and real-time capability for the calibration of the gas sensor.

[0121] In addition, according to the present invention, the lifespan of a gas detection sensor mounted on a portable gas detector is analyzed based on usage information to automatically generate replacement information, and an alarm is generated based on the generated gas detection sensor replacement information to notify the user, thereby enabling the user to always manage the portable gas detector optimally.

[0122] Although the invention made by the inventors has been specifically described according to the above embodiments, it is obvious to those skilled in the art that the invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof.
