Description

Technical Field

[0001] This application relates to the technical field of security monitoring, and in particular to a mobile visual intelligent monitoring and alarm device. Background Technology

[0002] In the fields of hazardous chemicals, industrial and commercial enterprises, and shipbuilding, operations are frequently conducted in confined spaces such as storage tanks, reaction vessels, ship holds, pipelines, and pits. These spaces often have restricted access and poor ventilation, making them prone to accumulating explosive and toxic gases, potentially leading to oxygen deficiency and asphyxiation, resulting in frequent poisoning accidents. Statistics show that between 2013 and 2022, there were 95 major confined space accidents in the industrial and commercial sectors, resulting in 357 deaths, with poisoning and asphyxiation accidents accounting for 96.8% of these.

[0003] Currently, the main solutions for safety monitoring in confined space operations are as follows: 1. Traditional portable gas detectors, while easy to carry, cannot transmit data over long distances. In the event of an accident, the outside cannot promptly ascertain the internal situation, potentially leading to blind rescue efforts; 2. Combining explosion-proof recorders with gas detectors, but these are usually manufactured by different companies, and the video can only be stored locally and cannot be synchronized with gas concentration data; 3. Combining explosion-proof surveillance cameras with gas detectors, but video transmission is not smooth or even impossible in confined spaces, resulting in the inside and outside being isolated at the moment of an accident, preventing timely rescue; 4. Some mobile gas detection alarms only have a single gas detection function, or use an external host, pump sampling, and cable camera setup. The camera, gas sampling end, and host are usually fixed in arrangement and connection, making it difficult to flexibly adjust between integrated and separate arrangements according to the size and operating conditions of different confined spaces. In scenarios such as confined spaces and pits, there are problems with the overall deployment of the device or the limited front-end acquisition capabilities; most products on the market do not consider the need for regular calibration and third-party verification, raising questions about the accuracy of detection after long-term use.

[0004] Furthermore, in enclosed spaces (mostly steel structures), existing wireless transmission solutions cannot guarantee low-latency and stable transmission of video and data. Information cannot be synchronized between operators, supervisors, and back-end management personnel. There is a lack of effective two-way voice communication and multi-terminal collaborative alarm mechanisms, as well as a lack of intelligent analysis capabilities for video images. It is also impossible to proactively warn of abnormal situations such as personnel falls, violations of regulations, and smoke and fire. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to propose a mobile visual intelligent monitoring and alarm device, which overcomes the problems of poor safety, unstable transmission and information blockage in confined spaces, and blind rescue expansion caused by the lack of intelligent early warning in existing equipment by arranging lithium batteries and electronic components in separate chambers, integrating MESH self-organizing network, multiple wired and wireless network access, and intelligent video analysis.

[0022] In one embodiment of this application, a display module is provided on the cover plate;

[0023] A glass plate is provided on the cover, and the glass plate is positioned corresponding to the display module.

[0024] In one embodiment of this application, the display module and the main control component are electrically connected for displaying real-time gas concentration data and alarm information locally, for on-site calibration and third-party verification.

[0025] In one embodiment of this application, the gas detection component includes a combustible gas detection unit, and at least one of an oxygen detection unit, a carbon monoxide detection unit, and a hydrogen sulfide detection unit, and is provided with a gas detection expansion interface for connecting other target gas detection units.

[0026] The gas detection component uses two sampling methods: diffusion sampling and pump-suction sampling. When using pump-suction sampling, the gas to be detected is delivered to the corresponding gas detection unit by a sampling pump.

[0027] In one embodiment of this application, the main control component is provided with a video image intelligent analysis module, which is used to intelligently identify the video images acquired by the video acquisition component, and the identified content includes at least one abnormal situation among people falling, smoke and fire, and not wearing a safety helmet.

[0028] In one embodiment of this application, the communication component synchronously transmits the video data, the gas concentration data, and alarm information to the background safety management platform and the on-site monitoring terminal.

[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0049] The mobile visual intelligent monitoring and alarm device according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0050] like Figure 1 As shown in the figure, the mobile visual intelligent monitoring and alarm device of this application embodiment may include:

[0051] An explosion-proof housing 1, wherein the explosion-proof housing 1 has an explosion-proof cavity and a battery mounting cavity 2 isolated from the explosion-proof cavity, and both sides of the explosion-proof housing 1 are provided with covers 3; the structure of the explosion-proof housing 1 is as follows. Figure 2 As shown.

[0052] It should be noted that the cover 3 includes a front cover and a rear cover. The front cover and the rear cover are respectively sealed to the explosion-proof housing 1 by bolts and sealing rings, forming a sealed space inside the explosion-proof housing 1 that meets the explosion-proof requirements.

[0053] In one embodiment of this application, the battery mounting cavity 2 is placed inside the explosion-proof housing 1, and the two ends of the battery mounting cavity 2 are through, as shown below. Figure 3 As shown, cover plates are provided on both sides of the battery mounting cavity 2 to seal the battery mounting cavity 2 and isolate the battery mounting cavity 2 from the explosion-proof cavity.

[0054] As one possible scenario, the two side covers of the battery mounting cavity 2 are fixedly connected to the battery mounting cavity 2 by bolts and sealed by sealing rings to close the battery mounting cavity 2.

[0055] Video capture component 4, such as Figure 4 As shown, the system includes an explosion-proof camera and a camera mounting interface 11 located on the top of the explosion-proof housing 1, used to collect video information about the working environment. The explosion-proof camera can be configured to operate in either an integrated or separate configuration depending on the working environment.

[0056] In the integrated working state, the explosion-proof camera is installed on the camera mounting interface 11 and forms a mechanical connection and a detachable electrical connection with the explosion-proof housing 1; in the split working state, the explosion-proof camera is detached from the camera mounting interface 11 and is separated from the explosion-proof housing 1 by an external explosion-proof cable.

[0057] In one embodiment of this application, reference is made to Figure 10 The explosion-proof camera is detachably connected to the explosion-proof housing 1 via a thread (camera mounting interface 11), which is used to mechanically fix the explosion-proof camera in an integrated working state. A sealing structure is provided at the connection point between the explosion-proof camera and the camera mounting interface 11 to ensure the sealing performance of the connection point.

[0058] As one possibility, the camera mounting interface 11 may be provided with a first multi-contact connection part, and the connection end of the explosion-proof camera may be provided with a second multi-contact connection part (not shown in the figure). The first multi-contact connection part and the second multi-contact connection part are respectively provided with corresponding power supply contacts and signal contacts, and can be connected to each other by magnetic attraction.

[0059] When the explosion-proof camera is screwed onto the camera mounting interface 11, the threaded connection structure mechanically fixes the explosion-proof camera. At the same time, the first multi-contact connection part and the second multi-contact connection part approach each other and complete the engagement of the corresponding contacts under the magnetic attraction. The power supply contact is used to establish the power supply path of the explosion-proof camera, and the signal contact is used to establish the video signal transmission path between the explosion-proof camera and the main control component 9.

[0060] Therefore, in the integrated working state, there is no need to lay out an exposed connecting wire between the explosion-proof camera and the explosion-proof housing 1 to complete the mechanical installation, power supply and video data transmission of the explosion-proof camera.

[0061] When the confined space is relatively small or it is necessary to separate the video acquisition position from the host placement position, the explosion-proof camera can be unscrewed from the camera mounting interface 11 to separate the first multi-contact connection part from the second multi-contact connection part, and a connection between the explosion-proof camera and the explosion-proof housing 1 can be established through an external explosion-proof cable, thereby forming a split-type working state.

[0062] It should be noted that, in one embodiment of this application, in the split-type working state, the detached explosion-proof camera is connected to the split-type acquisition base, thereby forming a front-end acquisition component with a volume smaller than the whole machine.

[0063] The split-type acquisition base is equipped with a gas sampling interface, which is connected to one end of a sampling tube. The other end of the sampling tube is connected to a gas detection component 10 mounted on the explosion-proof housing 1. Thus, the gas to be detected in the area where the front-end acquisition component is located can be transported to the gas detection component 10 via the gas sampling interface and the sampling tube.

[0064] The front-end acquisition component is also connected to the explosion-proof housing 1 via an explosion-proof cable. The explosion-proof cable is used to establish an electrical connection between the front-end acquisition component and the explosion-proof housing 1, so that the explosion-proof camera can obtain power and transmit the acquired video data to the main control component 9.

[0065] In this split-type layout, only the smaller front-end acquisition component can be placed inside the confined space, while the explosion-proof housing 1, main control component 9, communication component 5, and power supply component 6 can be placed outside the confined space. The explosion-proof camera acquires video information from inside the confined space, and the gas sampling interface on the split acquisition base acquires the gas to be detected at the corresponding location, thus simultaneously acquiring video and gas information from the same working area.

[0066] In a preferred embodiment, the camera mounting interface 11 can use an M20×1.5 standard thread. After the explosion-proof camera is removed from the camera mounting interface 11, an explosion-proof plug adapted to the M20×1.5 standard thread can be used to seal the camera mounting interface 11.

[0067] Furthermore, the charging port on the side of the explosion-proof housing 1 can be a multi-contact connector; when the device is charging, the multi-contact connector is connected to an external charging device. In the split-type working state, the multi-contact connector can also be connected to a dedicated explosion-proof cable to provide power supply and communication connection for the front-end acquisition component.

[0068] A gas detection component 10 is disposed on the explosion-proof housing 1 and is used to detect the concentration of one or more target gases in the working environment;

[0069] In one embodiment of this application, such as Figure 8 As shown, the gas detection component 10 includes a combustible gas detection unit, and at least one of an oxygen detection unit, a carbon monoxide detection unit, and a hydrogen sulfide detection unit.

[0070] For example, the combustible gas detection unit and the toxic and harmful gas detection units for oxygen, carbon monoxide, and hydrogen sulfide can be gas sensors, which can draw the gas in the working environment into the detection chamber for real-time detection through a built-in sampling pump.

[0071] In this embodiment, the sensor module includes at least one combustible gas detection unit (such as a catalytic combustion or infrared methane sensor), one oxygen detection unit (such as an electrochemical oxygen sensor), one carbon monoxide detection unit (such as an electrochemical carbon monoxide sensor), and one hydrogen sulfide detection unit (such as an electrochemical hydrogen sulfide sensor).

[0072] The gas detection component 10 may also be provided with a gas detection expansion interface, which is used to connect gas detection units for other target gases. Depending on the types of target gases required for detection in different operating environments, corresponding expansion gas detection units can be connected in addition to the basic gas detection unit, thereby forming a gas detection combination corresponding to the specific operating environment.

[0073] In one embodiment of this application, the gas detection component 10 uses two sampling methods: diffusion sampling and pump-suction sampling. When pump-suction sampling is used, the gas to be detected is delivered to the corresponding gas detection unit by a sampling pump.

[0074] When using diffusion sampling, the gas to be detected in the working environment diffuses naturally into the sensor cavity through the vent on the sensor cavity cover and comes into contact with the corresponding gas detection unit to complete the concentration detection.

[0075] When using pump-suction sampling, the gas detection component 10 uses a sampling pump to generate negative pressure, which transports the external gas to be detected through the sampling channel to the corresponding gas detection unit for concentration detection.

[0076] When the device is in the split-type working state, the sampling pump can be connected to the gas sampling interface on the split-type acquisition base through the sampling tube, and extract the gas to be detected at the location of the front-end acquisition component through the gas sampling interface.

[0077] The bottom of the explosion-proof housing 1 is provided with a sensor cavity cover, which is detachably connected to the explosion-proof housing 1 by threads. A sealing ring is provided at the connection between the sensor cavity cover and the explosion-proof housing 1 to ensure sealing performance. When it is necessary to maintain, replace or calibrate the sensor of the gas detection component 10, only the sensor cavity cover needs to be removed to take out the sensor module, without disassembling the entire explosion-proof housing 1.

[0078] Meanwhile, the sensor cavity cover is equipped with vent holes, which are covered with a waterproof and breathable membrane. This ensures that external gas can enter the sensor cavity and be detected by the sensor module when using diffusion sampling, while preventing moisture and dust from entering the sensor cavity.

[0079] The main control component 9 is located inside the explosion-proof cavity and is electrically connected to the video acquisition component 4 and the gas detection component 10. It is used to receive and process video data and gas concentration data. The main control component 9 includes a main control board, which is installed in the explosion-proof cavity inside the explosion-proof housing 1. The main control component 9 is also electrically connected to the communication component 5, the power supply component 6 and the alarm component 7.

[0080] The display module 8 is electrically connected to the main control component 9 and is used to display real-time gas concentration data and alarm information locally for on-site calibration and third-party verification.

[0081] In one embodiment of this application, the main control component 9 is provided with a video image intelligent analysis module, which is used to intelligently identify the video images acquired by the video acquisition component 4, and the identified content includes at least one abnormal situation among people falling, smoke and fire, and not wearing a safety helmet.

[0082] For example, when a person falls, it is determined that the person's physical condition is abnormal and an early warning signal is generated; when smoke or flames are detected in a video image, it is determined that the environment is abnormal and an early warning signal is generated; when a worker is not wearing a safety helmet, it is determined that this is a violation and an early warning signal is generated.

[0083] When the video image intelligent analysis module identifies the aforementioned anomaly and generates an early warning signal, the main control component 9 controls the alarm component 7 to issue an alarm signal. Simultaneously, the main control component 9 transmits the early warning signal and the corresponding video image to the backend security management platform via the communication component 5. The video image intelligent analysis module enables the mobile visual intelligent monitoring alarm device of this application to upgrade from passive monitoring to proactive early warning.

[0084] Communication component 5 is disposed inside the explosion-proof cavity and electrically connected to the main control component 9, and is used to transmit the video data and gas concentration data to the outside in a wireless and / or wired manner.

[0085] In one embodiment of this application, the communication component 5 includes a serial communication module, a serial network module, and a multi-port Ethernet switch.

[0086] As one possibility, the serial communication module can be a USR-T2 serial-to-Ethernet module, used to convert the serial data output by the main control component 9 into Ethernet data and connect it to the multi-port Ethernet switch.

[0087] refer to Figure 9 The gas concentration data collected by the gas detection component 10 is transmitted to the main control component 9. After receiving and processing the gas concentration data, the main control component 9 connects the gas concentration data to the local area network where the multi-port Ethernet switch is located through the serial communication module.

[0088] The video acquisition component 4 is connected to a multi-port Ethernet switch via an Ethernet interface, enabling the video data acquired by the video acquisition component 4 to enter the multi-port Ethernet switch.

[0089] A multi-port Ethernet switch is used to aggregate gas concentration data and video data, and to build a local area network within the device, so that data from the gas detection component 10 and the video acquisition component 4 can be transmitted through the same local area network.

[0090] The serial network module is used to connect to an external wireless communication network. Communication component 5 can establish a wireless communication connection with the multi-functional AP set up at the field monitoring end via MESH self-organizing network WiFi and / or industrial WiFi. The multi-functional AP receives gas concentration data, video data, and alarm information uploaded by the mobile visual intelligent monitoring and alarm instrument, and further sends the corresponding data to the background safety management platform.

[0091] Multi-port Ethernet switches also have Ethernet interfaces for wired network access. When wired network conditions are available on-site, or when confined spaces such as steel structures significantly impact wireless signal transmission, wired Ethernet can be used for data transmission.

[0092] Communication component 5 also supports 4G / 5G wireless network access, enabling the device to select the appropriate communication method from MESH self-organizing WiFi, industrial WiFi, 4G / 5G wireless network, or wired Ethernet based on the communication conditions available at different work sites. This ensures that video and gas detection data are processed synchronously, with low latency meeting users' needs for safety risk management and post-incident case traceability.

[0093] It should be noted that the explosion-proof housing 1 is equipped with an explosion-proof cable sealing joint for introducing power lines and / or communication cables into the explosion-proof cavity.

[0094] The communication component 5 transmits the video data, the gas concentration data, and the alarm information to the background safety management platform and the on-site monitoring terminal. At the same time, the alarm component 7 outputs corresponding alarm information at the operation end, so as to realize the synchronous alarm of the operation end, the monitoring end, and the control end.

[0095] Specifically, when the main control component 9 determines that the alarm conditions are met, it drives the alarm component 7 to issue an audible and visual alarm on the one hand, and sends the alarm information to the background safety management platform and the terminal device held by the on-site monitoring personnel through the communication component 5 on the other hand, while controlling the alarm component 7 at the working end to output alarm information.

[0096] After receiving the alarm information, the background safety management platform displays the alarm prompt on the platform interface and records detailed information such as alarm time, gas type, and real-time concentration. It can also link with the emergency management department. After receiving the alarm information, the on-site monitoring terminal reminds the monitoring personnel through voice and text prompts. The working end outputs an audible and visual alarm through the alarm component 7 and displays the corresponding alarm information through the display module 8, so that the workers in the confined space can obtain the on-site hazard information as soon as possible.

[0097] In one embodiment of this application, the mobile visual intelligent monitoring alarm device further includes a voice intercom component, which is connected to the main control component 9.

[0098] The voice intercom component may include a pickup unit for acquiring voice information from the work site and a sound output unit for outputting voice information. The voice information acquired by the work terminal is transmitted to the on-site monitoring terminal and / or the back-end safety management platform via the main control component 9 and the communication component 5. Voice information issued by on-site monitoring personnel or back-end management personnel can also be sent to the work terminal via the communication component 5 and played through the sound output unit.

[0099] This enables two-way voice communication between the work unit and the on-site monitoring terminal and / or the back-end safety management platform. In the event of gas concentration exceeding limits, personnel falling, or other abnormal situations, on-site monitoring personnel can communicate with the workers promptly via voice intercom, combining real-time video, gas concentration data, and alarm information.

[0100] The three-terminal synchronous alarm mechanism, combined with two-way voice communication, enables operators, on-site supervisors, and back-end management personnel to receive danger information simultaneously, effectively preventing blind rescue and increased casualties due to information gaps.

[0101] The power supply component 6 is disposed inside the battery mounting cavity 2, such as... Figure 6 As shown, it is electrically connected to the main control component 9 and is used to power the entire machine;

[0102] It is understood that the power supply component 6 is provided to supply power to the whole machine. The power supply component 6 includes a power supply battery (such as a lithium battery) which is disposed in the battery mounting cavity 2.

[0103] The lithium battery is detachably installed in the battery mounting cavity 2. The battery mounting cavity 2 is physically isolated from the electronic component mounting area in the explosion-proof cavity, and the lithium battery is completely separated from electronic components such as the main control component 9 and the communication component 5 by a partition. When the lithium battery needs to be replaced or maintained, it can be removed simply by removing the front or rear cover of the battery without opening the explosion-proof cavity, and without affecting the normal operation of the electronic components in the explosion-proof cavity.

[0104] In one embodiment of this application, at least one of the cover plates provided on both sides of the battery mounting cavity 2 is provided with a display module 8;

[0105] Specifically, in this embodiment, a display module 8 is provided on the battery rear cover, such as... Figure 8 As shown, the display module 8 can be an LCD screen or an OLED screen. A glass plate, which can be tempered glass, is provided on the cover 3 (e.g., the front cover of the explosion-proof housing 1). The glass plate and the display module 8 are positioned correspondingly, allowing the operator to observe the content displayed by the display module 8 through the glass plate. The glass plate is fixed to the cover 3 by a front cover glass fastening nut and sealed by a sealing ring.

[0106] Display module 8 is electrically connected to main control component 9 and is used to display real-time gas concentration data and alarm information locally. Specifically, display module 8 displays the concentration values ​​of various detected gases, detection time, equipment operating status, and alarm information in real time. Display module 8 also has a calibration setting function interface. Operators can enter the calibration setting mode through the touch screen or buttons of display module 8 and calibrate the gas detection component 10 by introducing standard gas.

[0107] It should be noted that, in this embodiment, the display module, in addition to displaying real-time concentration changes, also provides a user-friendly interface with settings including zero-point calibration, accuracy calibration, and alarm value settings applicable to different sectors such as hazardous chemicals and industrial and commercial applications. It also responds to the determination of gas detection concentration accuracy in standards such as GB50493, GB30871, and GB46768, facilitating third-party calibration.

[0108] The local display function of display module 8 makes it easy for on-site operators to understand the gas concentration status of the current working environment in a timely manner. It also makes it easy for equipment maintenance personnel to perform calibration by regularly purging standard gas and for third-party verification agencies to perform on-site verification, ensuring the accuracy of detection for long-term use of the equipment.

[0109] like Figure 7As shown, this is a side view of the mobile visual intelligent monitoring alarm device, which can be used to install switches and charging ports.

[0110] The alarm component 7 is disposed on the explosion-proof housing 1 and electrically connected to the main control component 9, and is used to issue an alarm signal when the alarm conditions are met.

[0111] The alarm component 7 includes an explosion-proof audible and visual alarm. When the gas concentration reaches a preset alarm threshold, the explosion-proof audible and visual alarm will emit an audible and visual alarm signal.

[0112] When the main control component 9 determines that the alarm conditions are met, it controls the explosion-proof audible and visual alarm to emit an audible and visual alarm signal. The audible and visual alarm signal includes a flashing red light and a high-frequency buzzer sound to attract the attention of on-site workers and people in the surrounding area.

[0113] When the main control component 9 determines that the alarm conditions are met, it simultaneously controls the alarm component 7 to issue an alarm signal and also controls the display module 8 to synchronously display alarm information. The alarm information includes at least one of the following: alarm type, alarm value, and alarm time. The alarm type includes gas concentration exceeding limits and video analysis anomaly; the alarm value includes the corresponding gas concentration value and / or the type of abnormal situation. The display module 8 displays the alarm information locally, allowing on-site personnel to promptly understand the alarm details.

[0114] The alarm conditions include at least one of the following: the gas concentration detected by the gas detection component 10 reaches a preset alarm threshold; or the main control component 9 identifies an abnormal situation through video image analysis. The preset alarm threshold can be set according to different operating environments and safety requirements, including a first-level alarm threshold and a second-level alarm threshold. When the gas concentration reaches different levels of alarm thresholds, the alarm component 7 can issue audible and visual alarm signals of different intensities.

[0115] As one possibility, the explosion-proof housing 1 is also provided with a handle, which allows operators to carry and move the device conveniently.

[0116] In summary, the mobile visual intelligent monitoring and alarm device of this application integrates gas detection, video acquisition, intelligent analysis, network transmission, three-terminal synchronous alarm, two-way voice intercom, and local display calibration, and achieves the separation of power supply components from other electronic components through mutually isolated explosion-proof cavities and battery mounting cavities.

[0117] The video acquisition component can be configured between an integrated working state and a split working state. In the integrated working state, the explosion-proof camera is mechanically fixed, powered, and the video signal is transmitted through a threaded and magnetic multi-contact connection structure. In the split working state, the explosion-proof camera, the split acquisition base, the gas sampling interface, the sampling tube, and the explosion-proof cable form a smaller front-end acquisition component to adapt to confined spaces.

[0118] The communication components transmit and aggregate video data and gas concentration data through serial communication modules, serial network modules, and multi-port Ethernet switches. They also support MESH self-organizing WiFi, industrial WiFi, 4G / 5G wireless networks, and wired Ethernet transmission, thus adapting to different equipment layout conditions and on-site communication environments in confined spaces, and enabling mobile, visual, and intelligent monitoring of confined space operating environments.
