Smart safety pole and manhole internal environmental monitoring system including it

[0001] The present invention relates to a smart safety pole and a manhole internal environment monitoring system including the same. The smart safety pole is detachably installed on one side of the inside of a manhole and is equipped with multiple sensors based on a BLE mesh network, thereby enabling a worker to recognize the internal environment of a manhole, thereby enabling the worker to prepare for a dangerous situation in advance before work or to respond to a dangerous situation occurring during work. The present invention relates to a smart safety pole and a manhole internal environment monitoring system including the same.

[0002] In general, manholes are formed so that workers can enter and exit to inspect, repair, or clean buried water pipes, sewer pipes, or wiring. These manholes are broadly classified into sewer manholes, water supply manholes, and electrical and communication manholes.

[0003] Sewer manholes are connected to underground sewer pipes. These sewer and wastewater pipes provide a path for sewage and wastewater from homes and buildings to be transported to a sewage treatment plant. Larger sewer pipes are accessible to personnel. For smaller pipes, an endoscope mounted on a robot, similar to an endoscope for gastroscopy, is used to inspect the pipe's condition.

[0004] Among these manholes, especially sewer manholes, the hydraulic characteristics (flow rate, flow velocity, etc.), water quality items (pH, COD, DO, etc.), and odor concentration inside the manholes should be temporarily measured when necessary.

[0005] In the past, when measuring odor, there was a problem in that the odor was released into the air the moment the manhole cover was opened and closed for measurement, making it difficult to accurately measure the odor because a worker had to enter the manhole.

[0006] Additionally, because workers must enter the manhole themselves, there is a risk of human casualties if toxic gases harmful to the human body exist inside the manhole.

[0007] Accordingly, in order to solve these problems, a system that can measure without the involvement of workers is required, but there is no system that can measure exclusively inside manholes and discharge odor reduction solutions.

[0008] The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a smart safety pole that is detachably installed on one side of the inside of a manhole and is equipped with multiple sensors based on a BLE mesh network, thereby enabling a worker to recognize the inside environment of a manhole, thereby enabling the worker to prepare for a dangerous situation in advance before work or to respond to a dangerous situation that occurs during work, and a manhole inside environment monitoring system including the same.

[0009] The present invention has the following features to solve the above problems.

[0010] The present invention comprises: a pole body formed in a longitudinal bar shape and detachably installed in a manhole; and a plurality of sensing units spaced apart from each other along the longitudinal direction of the pole body, each sensing unit generating desired sensing information and transmitting the sensing information to the outside; wherein the sensing unit comprises at least one of a carbon monoxide sensor, a carbon dioxide sensor, a hydrogen sulfide sensor, a methane sensor, and an oxygen sensor for detecting carbon monoxide, carbon dioxide, hydrogen sulfide, methane, and oxygen in the air in the manhole; at least one of a temperature sensor and a humidity sensor for detecting temperature and humidity in a set area in the manhole; a water level sensor, at least one of which is installed in a set area in the manhole, for detecting the water level of sewage in the manhole; and at least one of a 9-axis sensor and a radar sensor for detecting entry and exit and heart rate of a worker in the manhole, respectively.

[0011] Here, each sensor included in the sensing unit performs BLE communication with the outside, and each sensor is connected to the outside via a Bluetooth mesh network to transmit sensing information to the outside, and each sensor is formed so as to be attachable and detachable to a position set on the pole body.

[0012] In addition, an internal storage space is formed in the above-mentioned pole body to store a first battery, and the first battery is wired to a second battery stored within the manhole cover to supply power.

[0013] In addition, a manhole internal environment monitoring system according to one embodiment of the present invention includes: the smart safety pole; a manhole cover that receives sensing information from each sensor attached to the smart safety pole; a management server that receives sensing information from the manhole cover and generates status information of the manhole internal environment based on the received sensing information; and a worker terminal that receives sensing information from the manhole cover or receives status information of the manhole internal environment from the management server and outputs it to a user.

[0014] In addition, a biometric sensor is further included that is attached to a worker located in a manhole and transmits the worker's biometric information to the manhole cover, and the manhole cover includes a position sensor that detects whether the manhole cover has been removed from the manhole, and transmits sensing information generated from the position sensor to the management server or the worker terminal.

[0015] In addition, the status information of the internal environment of the manhole includes at least one of manhole opening information, manhole loss information, manhole flooding information, manhole fire information, and worker risk information, and the management server generates the manhole opening information and manhole loss information based on sensing information received from the position sensor of the manhole cover, generates the manhole flooding information based on sensing information received from the water level sensor of the safety pole, generates the manhole fire information based on sensing information received from the temperature sensor and the radar sensor of the safety pole, and generates worker risk information based on sensing information received from the radar sensor of the safety pole and the biometric sensor.

[0016] In addition, the management server generates the expected flooding speed, the expected fire activation speed, and the hourly worker risk index based on the sensing information received from each sensor when generating the manhole flooding information, manhole fire information, and worker risk information, and transmits the generated information to the worker terminal and a preset external control server.

[0017] In addition, the management server generates safety precautions that are judged to be necessary for workers to be aware of while working in the current manhole environment based on at least one of the status information of the manhole internal environment, the expected submergence speed, the expected fire activation speed, and the hourly worker risk index, and transmits the generated safety precautions to the worker terminal.

[0018] According to the present invention, a smart safety pole is installed detachably on one side of the inside of a manhole and is equipped with multiple sensors based on a BLE mesh network, thereby enabling a worker to recognize the environment inside the manhole, thereby enabling the worker to prepare for a dangerous situation in advance before work or to respond to a dangerous situation that occurs during work.

[0019] In addition, manhole opening information, manhole loss information, manhole flooding information, manhole fire information, and worker risk information can be checked in real time, and when generating manhole flooding information, manhole fire information, and worker risk information, the expected flooding speed, expected fire activation speed, and hourly worker risk index can be generated based on the sensing information received from each sensor and provided to the worker terminal and a preset external control server, which has the effect of enabling a quick response to the occurrence of a risk.

[0020] Additionally, it has the effect of preventing the occurrence of risks at the source by providing workers with safety precautions that they should be aware of before starting work inside a manhole.

[0023] FIG. 3 is a block diagram schematically illustrating the configuration of a manhole internal environment monitoring system according to one embodiment of the present invention.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted to clearly explain the present invention, and the same reference numerals are used throughout the specification for identical or similar components. In addition, detailed descriptions of widely known and publicly known technologies are omitted.

[0025] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0026] FIG. 1 is a drawing showing a smart safety pole according to an embodiment of the present invention installed inside a manhole, and FIG. 2 is a block diagram showing the internal configuration of a smart safety pole according to an embodiment of the present invention.

[0027] Referring to the drawings, a smart safety pole (1000) according to one embodiment of the present invention is largely composed of a pole body (100) formed in the shape of a length bar and installed so as to be detachable within a manhole, and a sensing unit (200) that is installed in multiple pieces spaced apart along the length direction of the pole body (100) and generates each desired sensing information and transmits the sensing information to the outside.

[0028] Here, the above-mentioned pole body (100) may be configured to be attached to and detached from one side of the inside of the manhole, i.e., a ladder for a worker to descend into the manhole, as an example, or may be configured to be attached and detached vertically to the inside wall of the manhole as another example.

[0029] As an example, the detachable configuration of this foam body (100) may be configured such that a plurality of separate guide members are arranged vertically on the inner wall of the manhole, the lowermost guide member has a lower surface formed to support the pole body (100), and the remaining upper guide members have upper and lower portions open to allow the pole body (100) to be inserted or withdrawn.

[0030] In addition, the pole body (100) can be installed in various forms so as to be detachable inside the manhole, and the present invention is not limited thereto.

[0031] Accordingly, before a worker goes down into the manhole to detect the internal environment of the manhole, the pole body (100) can be withdrawn from the inside of the manhole, the sensing unit (200) can be installed, and then the pole body (100) can be repositioned inside the manhole.

[0032] Of course, depending on the settings, the sensing unit (200) composed of multiple sensors may be installed on the pole body (100) for a certain period of time, and the pole body (100) may be positioned inside the manhole.

[0033] Accordingly, it is possible to monitor the inside environment of a manhole in real time at any time without any work by a worker, and the worker can pull out the pole body (100) outside the manhole to perform tasks such as combining the pole body (100) of the sensing unit (200) or replacing or additionally installing a specific sensor, and then reinsert it into the manhole after the intended task and install it.

[0034] In addition, a certain accommodation space is formed inside the pole body (100) to accommodate a first battery (110) that supplies power to a plurality of sensors attached to the pole body (100).

[0035] This first battery (110) can be wired to supply power to a second battery (1110) within a manhole cover (1100) provided to open or close a manhole according to settings or requests.

[0036] Meanwhile, the sensing unit (200) is installed in multiple numbers spaced apart from each other along the length direction of the pole body (100) and is provided to generate target sensing information and transmit the sensing information to the outside. The sensing unit (200) is configured with at least one of a carbon monoxide sensor (210), a carbon dioxide sensor (211), a hydrogen sulfide sensor (212), a methane sensor (213), and an oxygen sensor (214) that detect carbon monoxide, carbon dioxide, hydrogen sulfide, methane, and oxygen in the air inside the manhole, at least one of a temperature sensor (220) and a humidity sensor (230) that detect the temperature and humidity of a set area inside the manhole, at least one water level sensor (240) that is installed in a set area inside the manhole and detects the water level of sewage inside the manhole, and at least one of a 9-axis sensor (250) and a radar sensor (260) that detect the entry and exit and heart rate of a worker inside the manhole, respectively.

[0037] Each sensor included in this sensing unit (200) performs BLE communication with the outside, and each sensor is connected to the outside via a Bluetooth mesh network to transmit sensing information to the outside, and each sensor is formed so that it can be attached or detached to a position set on the pole body (100).

[0038] In one embodiment of the present invention, each sensor constituting the sensing unit (200) is connected to the BLE communication unit (1120) of the manhole cover (1100), and each sensor is connected to a Bluetooth mesh network. This Bluetooth mesh network is basically a mesh network that connects each sensor and the BLE communication unit (1120) using Bluetooth technology.

[0039] Each of these sensors operates on the basis of BLE (Bluetooth Low Energy), and the Bluetooth chip mounted on each sensor must be configured as Bluetooth v4.0 or higher to enable Bluetooth mesh networking.

[0040] Meanwhile, each of the sensors described above, i.e., carbon monoxide sensor (210), carbon dioxide sensor (211), hydrogen sulfide sensor (212), methane sensor (213), oxygen sensor (214), temperature sensor (220), humidity sensor (230), water level sensor (240), 9-axis sensor (250), and radar sensor (260), can be set and removed by the worker according to the characteristics of the inside of the manhole to be monitored or worked on, and a microphone sensor (270) can be additionally installed to enable smooth communication between the worker and an external manager.

[0041] In addition, the above 9-axis sensor (250) is equipped to enable tracking of the worker's motion through measurements of acceleration, gyro, geomagnetism, etc., and the radar sensor (260) enables measurement of the worker's heart rate through the Doppler effect and generates environmental information inside the manhole, enabling detection of worker entry and exit and falling accidents during work.

[0042] FIG. 3 is a block diagram schematically illustrating the configuration of a manhole internal environment monitoring system according to one embodiment of the present invention.

[0043] Referring to the drawings, a manhole internal environment monitoring system (2000) according to an embodiment of the present invention is largely composed of the aforementioned smart safety pole (1000), a manhole cover (1100) that receives sensing information from each sensor attached to the pole body (100) of the smart safety pole (1000), a management server (1200) that receives sensing information from the manhole cover (1100) and generates status information of the internal environment of the manhole based on the received sensing information, a worker terminal (1300) that receives sensing information from the manhole cover (1100) or receives status information of the internal environment of the manhole from the management server (1200) and outputs it to a user, and a biometric sensor (1400) that is attached to a worker located in a manhole and transmits biometric information of the worker to the manhole cover (1100).

[0044] Here, the smart safety pole (1000) is configured as described above, and the sensing unit (200) installed in the pole body (100) transmits sensing information to the BLE communication unit (1120) of the manhole cover (1100).

[0045] In addition, the manhole cover (1100) is equipped to receive sensing information from the sensing unit (200) attached to the pole body (100) of the smart safety pole (1000) and transmit the same to the management server (1200) or the worker terminal (1300). The manhole cover (1100) is configured with a second battery (1110) that supplies power to components within the manhole cover, a BLE communication unit (1120) that performs BLE-based networking with the sensing unit (200) and the biometric sensor (1400) of the smart safety pole (1000), a second communication unit (1130) that performs LoRa communication or LTE communication with the management server (1200) or the worker terminal (1300), and a position sensor (1140) that detects whether the manhole cover (1100) has been removed from the manhole.

[0046] Here, the sensing information generated from the position sensor (1140) is transmitted to the management server (1200) or the worker terminal (1300) to provide information on whether the manhole cover (1100) has moved from its original position. This departure information can be classified into opening information indicating whether the manhole cover has moved to a short distance from the manhole and opened, and loss information indicating whether the manhole cover has moved to a long distance from the manhole and been lost.

[0047] Meanwhile, the management server (1200) is provided to receive sensing information from the manhole cover (1100) and generate status information of the internal environment of the manhole based on the received sensing information. The status information of the internal environment of the manhole is composed of at least one of manhole opening information, manhole loss information, manhole flooding information, manhole fire information, and worker risk information.

[0048] To this end, the management server (1200) generates manhole opening information and manhole loss information based on sensing information received from the position sensor of the manhole cover (1100), generates manhole flooding information based on sensing information received from the water level sensor (240) of the smart safety pole (1000), generates manhole fire information based on sensing information received from the temperature sensor (220) and radar sensor (260) of the smart safety pole (1000), and generates worker risk information based on sensing information received from the radar sensor (260) of the smart safety pole (1000) and the biometric sensor (1400).

[0049] In addition, the management server (1200) generates the expected flooding speed, the expected fire activation speed, and the hourly worker risk index based on the sensing information received from each sensor when generating the manhole flooding information, manhole fire information, and worker risk information, and transmits them to the worker terminal (1300) and a preset external control server.

[0050] Here, the management server (1200) can train an AI-based machine learning model using the sensing information of each sensor collected when generating an hourly worker risk index, the manhole flooding information, manhole fire information, and worker risk information generated through the same, and the flooding expected speed and fire expected activation speed generated through the same as input data.

[0051] These machine learning models are generated through machine learning by receiving each of the above information as an input data set containing labels according to object class, and are configured to enable more accurate object detection by further segmenting the object class and assigning weighted labels as well as result value labels.

[0052] Here, the weighted label is learned by assigning weights to each object class described above in the learning process for the machine learning model to generate the hourly worker risk index. For example, the weight with the highest weight corresponds to the biometric information received from the biometric sensor (1500) according to an example of the present invention, and next, the expected flooding speed and the expected fire activation speed can be applied.

[0053] For example, biometric information can be set to 1, expected flood speed and expected fire activity information can be set to 0.7, and each other sensing information can be set to 0.4.

[0054] Meanwhile, the external control servers set above may include fire control and police servers for fire suppression or worker rescue.

[0055] In addition, the hourly worker risk index can be used to predict future changes in the worker's body weight on an hourly basis based on the worker's biometric information and the manhole interior environmental information, and can be provided to the worker as well as firefighters dispatched to rescue the worker.

[0056] In addition, the management server (1200) can generate safety precautions that are judged to be necessary for workers to be aware of when working in the current manhole environment based on the status information of the manhole internal environment, the expected submergence speed, the expected fire activation speed, and the hourly worker risk index, and transmit the generated safety precautions to the worker terminal (1300). The worker terminal (1300) that receives the safety precautions provides the safety precautions to the user, so that the worker can be aware of the current manhole internal environment before working and check the necessary safety precautions before working, thereby preventing the occurrence of danger.

[0057] Meanwhile, in the manhole internal environment monitoring system (2000) of the present invention, a BLE-based smart meter (1500) is installed separately in a meter placed inside the manhole, so that the manhole cover (1100) receives metering information from the smart meter (1500) without the need for the worker to check it daily, and the management server (1200) and the worker terminal (1300) can check it in real time.

[0058] While preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. That is, those skilled in the art to which the present invention pertains may make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications should be considered equivalents and fall within the scope of the present invention.
