AI Technical Summary
When working in confined spaces (such as pipelines, tanks, underground spaces, etc.), poor ventilation, small space and poor signal make it impossible to monitor workers in real time and give timely warnings of danger, which increases safety risks.
The device uses a movable column to carry a controller, network module, repeater, gas monitor, vital signs monitor, and image acquisition device. It connects to a cloud platform through the network module to monitor gas concentration in real time and issue an alarm when the concentration exceeds the standard. It also combines gas and vital signs monitors worn by personnel to transmit data back in real time and issue warnings.
It enables real-time monitoring and hazard alerts for underground workers, reducing safety risks and ensuring worker safety and operational visibility.

[0021] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0022] The application discloses a mobile monitoring device and system for a limited space, aiming to eliminate the operation risk that may exist when a worker operates in a limited space.
[0023] Please refer to Figure 1 The first embodiment of the application provides a mobile monitoring device for a limited space, comprising a movable stand, a controller arranged on the movable stand, a network module electrically connected to a radio frequency end of the controller, a repeater electrically connected to the network module, a first gas monitor electrically connected to an input end of the controller, and a plurality of second gas monitors for being worn on a human body and wirelessly connected to the repeater.
[0024] It should be noted that the use scenario of the application is in an underground pipeline or a bottom tank, which has poor ventilation conditions. Therefore, the mobile monitoring device needs to be placed into the space before a worker enters. The first gas monitor can collect the gas condition in the limited space and transmit it to the controller. The controller can be a single-chip microcomputer of an STM32 series, but is not limited to the single-chip microcomputer. The controller can transmit the gas condition to a terminal or a cloud platform through the network module. The first gas monitor will issue an alarm when some gas concentration exceeds a standard (for example, carbon monoxide, hydrogen sulfide gas, or flammable gas) or the oxygen concentration is lower than a preset value. Of course, the terminal or the cloud platform will also issue an alarm, prompting the worker not to enter or to enter after taking protective measures. The second gas monitor is used for being worn on the worker's body and can monitor the gas condition at the current position in real time. The second gas monitor can issue an alarm when it is determined that the gas concentration at the current position is abnormal.
[0025] Further, in the present embodiment, the network module can be configured at the top of the movable column, and the repeater can be configured at the bottom of the movable column.
[0026] It should be noted that, taking the sewage pipeline limited space operation as an example, it refers to the work activities related to the drainage pipeline in a closed or partially closed space, such as entering the inside of the tank to install the grid and other work. After the worker enters the shaft, the network signal will quickly attenuate. In the present embodiment, the network module can be but not limited to a 5G module or other network-enabled network module. The network module configured at the top can maintain networking, while the repeater configured at the bottom can wirelessly connect with the second gas monitor configured on the worker's body, avoiding the inability to return the gas data at the worker's location due to the lack of internal signal.
[0027] Further, the present embodiment further includes a lighting device movably configured on the column, which is designed to provide stable and adjustable light source support for limited space operation environment, ensuring the visibility of operation under various light conditions. The lighting device as a whole adopts a modular design, which can be flexibly installed at different heights and angles of the movable column, providing a bright working environment for the workers.
[0028] Further, the present embodiment further includes a plurality of body sign monitors for wearing on the human body wirelessly connected with the repeater.
[0029] It should be noted that the body sign monitor can be a bracelet worn on the hand, which can collect real-time vital sign data such as heart rate, blood oxygen saturation, body temperature, etc., thereby helping to identify possible physiological abnormalities such as excessive fatigue, hypoxia, etc. Especially in harsh conditions, it can provide the most direct safety guarantee. For example, when the heart rate or blood oxygen content exceeds the safety threshold, the monitor will immediately send an alarm signal to the repeater, and then notify the safety officer through the network module.
[0030] Further, the present embodiment further includes an image acquisition device configured on the movable column, wherein the image acquisition device is electrically connected with the input end of the controller.
[0031] It should be noted that the image acquisition device arranged on the movable column is used to capture image and video data in the limited space in real time, and the captured image data is directly transmitted to the controller for processing. The terminal or cloud platform can access the image or video data in real time through the network module. The image acquisition device can be a high-definition camera that can provide clear pictures in complex and low-light conditions. By using wide dynamic range (WDR) and low-light enhancement technology, the camera can capture detailed images even in a limited space with extremely insufficient light, thereby ensuring the real-time visibility of the monitoring system to the scene.
[0032] Further, the embodiment can further include a UPS power supply electrically connected to the power supply end of the movable column. The UPS power supply can continuously supply power to the equipment in the case of sudden power failure or voltage fluctuation, and ensure the continuous operation of the key monitoring and data acquisition device.
[0033] The second embodiment of the application provides a mobile monitoring system for a limited space, which comprises a cloud platform and a mobile monitoring device for a limited space according to any one of the above embodiments, wherein the controller can establish a communication connection with the cloud platform through the network module.
[0034] Based on the mobile monitoring device and system for a limited space provided by the application, the controller and the first gas monitor are electrically connected to receive the gas concentration at the column in real time. When the concentration of some gases (such as carbon monoxide, hydrogen sulfide gas, or flammable gas) exceeds the standard or the oxygen concentration is lower than the preset value, an alarm will be issued. Of course, the terminal or cloud platform will also issue an alarm, prompting the staff not to enter or to enter after taking protective measures. The second gas monitor worn on the staff can return the collected data through the repeater to monitor the gas situation at the current position in real time. When it is determined that the gas concentration at the current position is abnormal, an alarm will be issued, solving the problems of being unable to monitor the underground workers in real time and being unable to give a danger prompt.
