Description

Technical Field

[0001] This invention relates to the field of intelligent inspection terminal technology, specifically to a multifunctional intelligent inspection terminal and its control method. Background Technology

[0002] Fire safety inspections are a core part of fire prevention, aiming to ensure all fire-fighting facilities are always in good working order and ready for use. However, when inspecting underground utility tunnels, the tunnels are often long and narrow, ranging from hundreds of meters to tens of kilometers in length, but with limited cross-sectional space (height and width mostly 2-4 meters). This narrow and enclosed structure results in extremely poor natural ventilation, obstructed visibility, and a high risk of getting lost. Furthermore, some tunnels are single-story with all pipelines on the same cross-section, while others are double-story or multi-story, with separate electrical, gas, and water / communication compartments, isolated from each other. This makes inspection routes complex. Current inspection methods typically rely on manual inspections, but due to the complexity of the routes, quick and accurate inspections are impossible, leading to omissions or repeated inspections of certain locations, thus reducing inspection efficiency.

[0003] Furthermore, underground corridors harbor various hazards, such as toxic and harmful gases like hydrogen sulfide (H2S), methane (CH4), carbon monoxide (CO), and carbon dioxide (CO2). Insufficient ventilation within the pipelines can easily lead to oxygen deficiency. In addition, groundwater leakage, pipe condensation, and flushing drainage can easily cause water accumulation at the bottom, making the floor slippery and increasing the risk of falls. The accumulated water may also conduct electricity, increasing the risk of electric shock. During inspections, adequate safety measures and alarm / rescue procedures are lacking.

[0004] Therefore, there is an urgent need for a highly integrated, fast-responding, multifunctional intelligent inspection terminal and its control method that can monitor personnel safety. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multifunctional intelligent inspection terminal and its control method to solve the problems in the background art, realize multifunctional safety inspection, and adapt to fire inspection in the complex environment of underground corridors.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0007] A multifunctional intelligent inspection terminal includes a helmet body, a waist belt, and a main unit. The helmet body includes an outer shell layer, a buffer layer, a middle compartment layer, and an inner liner layer. The middle compartment layer is equipped with a voice communication module, a helmet positioning module, a communication module, a gas detection module, a safety detection module, and a voice alarm module. The controlled ends of the voice communication module and the voice alarm module are connected to the output end of the main unit, and the output ends of the helmet positioning module, the gas detection module, and the safety detection module are connected to the input end of the main unit. The outer shell layer of the helmet body is equipped with a camera, a supplementary light, a warning light, and a gas source inlet. The controlled end of the warning light is connected to the output end of the main unit, and the gas source inlet is connected to the gas detection module through a gas source delivery pipeline. The waist belt is equipped with a power module, a waist belt positioning module, and a Bluetooth communication module. The output end of the waist belt positioning module is connected to the input end of the main control module, and a charging module is also provided on the waist belt.

[0008] The aforementioned multifunctional intelligent inspection terminal includes a charging module comprising magnetic contacts on the surface of a belt and a power cord connected to the helmet body. One end of the power cord is provided with a magnetic head that connects to a magnetic base on the rear side of the helmet body.

[0009] The aforementioned multifunctional intelligent inspection terminal includes a voice communication module comprising a bone conduction headset and a bone conduction microphone. The bone conduction microphone is mounted on the throat strap of the helmet body, and the bone conduction headset is mounted on the inner lining layer near the ears of the helmet body.

[0010] The aforementioned multifunctional intelligent inspection terminal includes a gas detection module comprising a miniature gas sensor module integrating five gas sensors: CH4, CO, CO2, H2S, and O2.

[0011] The aforementioned multifunctional intelligent inspection terminal is equipped with a dust filter at the air source inlet and a miniature air pump on the air source delivery pipeline.

[0012] The aforementioned multifunctional intelligent inspection terminal includes a safety detection module comprising a heart rate and blood oxygen sensor module located in the intermediate cabin layer.

[0013] A control method for a multi-functional intelligent inspection terminal, the method being implemented based on the aforementioned multi-functional intelligent inspection terminal, includes the following operations: S1. The host generates inspection task information containing the inspection route according to the current inspection requirements, and sends the inspection task information to the intelligent inspection terminal through the communication module. The inspection task information is pre-set with the detection points and detection items in the planned route. S2. After receiving the inspection task information, the intelligent inspection terminal conducts inspections according to the route in the inspection task information, takes real-time photos and uploads them through the camera, and obtains location information in real time during the process. If the location information does not correspond to the location of the detection point, it continues to move forward. If the location information corresponds to the location of the detection point, it proceeds to the next step. S3. Upon arrival at the testing point, a prompt is issued via the voice communication module, and the corresponding tests are carried out according to the testing items. The information of the testing point is then transmitted to the host for analysis and summarization. S4. After the inspection is completed, the host determines whether there is any missed inspection based on the received information. If there is a missed inspection, the inspection route is regenerated and the host returns to step S2 to re-inspect the missed inspection points. If there is no missed inspection, the host returns to the original route or enters the next inspection route according to the instructions.

[0014] In the control method of the above-mentioned multifunctional intelligent inspection terminal, in step S2, the helmet positioning module and the waist belt positioning module send positioning information to the host respectively. The host compares the two positioning information. The helmet and waist belt positioning data are fused by Kalman filtering. When they are inconsistent, the high-precision source is automatically selected according to the confidence level and the difference log is recorded. When the deviation between the two exceeds the safety threshold and lasts for more than 5 seconds, a voice prompt and a red warning light flashing prompt are triggered.

[0015] In the control method of the aforementioned multifunctional intelligent inspection terminal, in step S2, if the location information does not change for more than 5 minutes during the movement and there is no other information feedback, a voice prompt and a red warning light flashing are triggered. At this time, the heart rate and blood oxygen sensor module is used for detection. If the heart rate exceeds the set value, the location information is provided to the host and a distress signal is sent. If the heart rate is normal, the voice prompt module is used to wake up and provide prompts, and the current status is communicated in real time.

[0016] In the control method of the above-mentioned multifunctional intelligent inspection terminal, in step S3, under normal working conditions, the micro air pump adopts an intermittent working mode and has a built-in flow meter to monitor the air volume in real time. The main control module ensures that the air volume is stable each time through PID adjustment or closed-loop control, thereby reducing power consumption and extending the sensor life. When the concentration of any gas reaches 80% of the preset warning value or the rate of change of concentration exceeds the set threshold, the main control module automatically switches the micro gas pump to continuous sampling mode to monitor the gas concentration in real time until the concentration returns to normal and remains stable for a period of time, and then switches back to intermittent mode.

[0017] Due to the adoption of the above technical solutions, the technical progress achieved by this invention is as follows.

[0018] This invention provides a multifunctional intelligent inspection terminal and its control method. The helmet body and waist belt work together. The helmet body integrates a positioning module, a communication module, a gas detection module, an alarm module and a safety detection module. It works with the host to plan the inspection route and can carry out accurate and fast inspections according to the planned route. This solves the problems of low efficiency and poor safety of existing underground corridor inspections, and is therefore well applied to fire inspections of underground corridors.

[0019] The belt serves as the main power source, enabling continuous power supply and avoiding frequent battery replacements or recharging. This significantly extends the time for a single inspection operation and prevents task interruptions due to insufficient power.

[0020] This invention combines a heart rate and blood oxygen sensor with a static timeout detection mechanism to automatically identify dangerous states such as unconsciousness and sudden illness, and actively send location and distress signals, providing critical information for emergency rescue and significantly improving the personal safety of inspection personnel.

[0021] During the inspection process, the host computer issues inspection tasks containing preset routes. The terminal automatically compares its current location with the location of the inspection point, and inspection operations are only allowed after reaching the inspection point. After the inspection is completed, the system automatically determines whether there are any missed inspections and guides the system to conduct supplementary inspections. This achieves closed-loop control of the entire process from task issuance, execution, verification to data upload, effectively preventing missed inspections and incorrect inspections caused by human error, and achieving accurate and efficient inspections.

[0022] Figure 1 This is a schematic diagram of the specific structure of the present invention; Figure 2 This is a structural block diagram of the present invention; Figure 3 This is a flowchart of the present invention.

[0023] The components are: 101. Helmet body, 102. Camera, 103. Fill light, 104. Warning light, 105. Air inlet, 106. Helmet quick-release slide rail, 107. Waist belt, 108. Waist belt quick-release slide rail. Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] A multi-functional intelligent inspection terminal, such as Figures 1 to 2As shown, the helmet includes a helmet body 101, a waist belt 107, and a main unit. The helmet body 101 includes an outer shell layer, a buffer layer, a middle chamber layer, and an inner liner layer. The middle chamber layer is equipped with a voice communication module, a helmet positioning module, a communication module, a gas detection module, a safety detection module, and a voice alarm module. The controlled ends of the voice communication module and the voice alarm module are connected to the output end of the main unit, and the output ends of the helmet positioning module, the gas detection module, and the safety detection module are connected to the input end of the main unit.

[0026] The helmet body 101 has a camera 102, a fill light 103, a warning light 104, and an air inlet 105 on its outer shell. The controlled end of the warning light 104 is connected to the output end of the host. The air inlet 105 is connected to the gas detection module through the air supply pipeline. The helmet body 101, camera 102, fill light 103, and warning light 104 are each equipped with a lithium battery. The waist belt 107 is equipped with a power module, a waist belt positioning module, and a Bluetooth communication module. The output end of the waist belt positioning module is connected to the input end of the main control module. The waist belt 107 is also equipped with a charging module for charging the camera, fill light, warning light, and helmet body.

[0027] The helmet body 101 is equipped with a helmet quick-mount rail 106 for quickly mounting a camera 102, a fill light 103, and a warning light 104, which facilitates the removal of devices with low power.

[0028] The belt 107 is equipped with a belt quick-mount rail 108 for quickly mounting the camera 102, fill light 103, and warning light 104, which is used to hang the camera 102, fill light 103, and warning light 104 on the belt for charging.

[0029] The main control module has data acquisition, analysis, storage and uploading functions, such as recording gas concentration, location trajectory, video recording, etc., and supports local storage (such as TF card) and cloud synchronization.

[0030] The charging module includes magnetic contacts disposed on the surface of the waist belt 107 and corresponding to the waist belt quick-release slide rail 108, and a power cord connected to the helmet body 101. One end of the power cord is provided with a magnetic head that connects to the magnetic base on the rear side of the helmet body 101, which facilitates charging the helmet body.

[0031] The voice communication module includes a bone conduction headset and a bone conduction microphone. The bone conduction microphone is mounted on the throat strap of the helmet body, and the bone conduction headset is mounted on the inner lining near the ears of the helmet body. It is used to play audio for remote communication. The bone conduction headset does not block the ear canal and can receive external sounds. The headset collects the wearer's voice through the bone conduction microphone to achieve remote communication.

[0032] The gas detection module includes a miniature gas sensor module that integrates five gas sensors: CH4, CO, CO2, H2S, and O2. It can simultaneously detect the concentration of these five gases and transmit the signals to the main control module. The main control module then determines whether an alarm is needed based on the built-in preset alarm rules.

[0033] A dust filter is installed at the gas inlet 105, and a miniature air pump is installed on the gas delivery pipeline. The miniature air pump actively draws air, avoiding detection delays caused by natural diffusion.

[0034] The miniature air pump operates intermittently and has a built-in flow meter to ensure a stable pumping volume. When the gas concentration is abnormal, it automatically switches to continuous sampling.

[0035] The safety detection module includes a heart rate and blood oxygen sensor module located in the intermediate cabin, which can effectively monitor heart rate status and provide alarm prompts through a voice alarm module and warning lights.

[0036] The helmet positioning module and the waist belt positioning module use Beidou + GPS positioning respectively, and with the cooperation of 5G communication base stations, they can achieve accurate positioning and stable communication.

[0037] A control method for a multi-functional intelligent inspection terminal, the method being implemented based on the aforementioned multi-functional intelligent inspection terminal, such as... Figure 3 As shown, the method includes the following operations: S1. The host generates inspection task information containing the inspection route based on the current inspection requirements, and sends the inspection task information to the intelligent inspection terminal through the communication module. The inspection task information pre-sets the detection points and detection items in the planned route.

[0038] S2. After receiving the inspection task information, the intelligent inspection terminal conducts inspections according to the route in the inspection task information, takes real-time photos and uploads them through the camera, and obtains location information in real time during the process. If the location information does not correspond to the location of the detection point, it continues to move forward. If the location information corresponds to the location of the detection point, it proceeds to the next step.

[0039] In this step, the helmet positioning module and the waist belt positioning module send positioning information to the host respectively. The host compares the two positioning information. The helmet and waist belt positioning data are fused through Kalman filtering. When they are inconsistent, the high-precision source is automatically selected according to the confidence level and the difference log is recorded. When the deviation between the two exceeds the safety threshold (such as 10 meters) and lasts for more than 5 seconds, a voice prompt and a red warning light flashing are triggered.

[0040] If the location information remains unchanged for more than 5 minutes without any other feedback during the journey, a voice prompt and a flashing red warning light will be triggered. At this time, the heart rate and blood oxygen sensor module will detect the heart rate. If the heart rate exceeds the set value, the system will provide the location information to the host and send a distress signal. If the heart rate is normal, the system will wake up and provide prompts through the voice prompt module, communicating the current status in real time.

[0041] S3. Upon arrival at the testing point, a prompt is issued via the voice communication module, and the corresponding tests are performed according to the testing items. The information of the testing point is then transmitted to the host for analysis and summarization.

[0042] During the testing process, under normal operating conditions, the miniature air pump adopts an intermittent working mode (e.g., pumping air for 5 seconds every 30 seconds) and has a built-in flow meter to monitor the pumping volume in real time. The main control module ensures that the pumping volume is stable each time through PID (proportional-integral-derivative) adjustment or closed-loop control, thereby reducing power consumption and extending the sensor life.

[0043] When the concentration of any harmful gas reaches 80% of the preset warning value or the rate of change of concentration exceeds the set threshold, or when the oxygen concentration is 30% lower than the preset warning value, the main control module automatically switches the micro gas pump to continuous sampling mode to monitor the gas concentration in real time until the concentration returns to normal and remains stable for a period of time, and then switches back to intermittent mode.

[0044] When the concentration of any harmful gas reaches the preset warning value or the oxygen concentration is lower than the preset warning value, the alarm mode is triggered. After receiving the alarm signal, the host will replan a suitable route to transfer the inspection personnel to a safe location or remind the inspection personnel to evacuate in time according to the optimal route.

[0045] S4. After the inspection is completed, the host determines whether there is any missed inspection based on the received information. If there is a missed inspection, the inspection route is regenerated and the host returns to step S2 to re-inspect the missed inspection points. If there is no missed inspection, the host returns to the original route or enters the next inspection route according to the instructions.

[0046] In environments with high oxygen deficiency, positive pressure breathing masks and portable oxygen cylinders can be used. An electronic pressure gauge should be installed on the oxygen cylinder filling line and electrically connected to the communication module so that an alarm signal can be issued in time when the pressure inside the cylinder is low.

[0047] This invention provides a multifunctional intelligent inspection terminal and its control method. The helmet body and waist belt work together. The helmet body integrates a positioning module, a communication module, a gas detection module, an alarm module and a safety detection module. It works with the host to plan the inspection route and can carry out accurate and fast inspections according to the planned route. This solves the problems of low efficiency and poor safety of existing underground corridor inspections, and is therefore well applied to fire inspections of underground corridors.

[0048] The belt serves as the main power source, enabling continuous power supply and avoiding frequent battery replacements or recharging. This significantly extends the time for a single inspection operation and prevents task interruptions due to insufficient power.

[0049] This invention combines a heart rate and blood oxygen sensor with a static timeout detection mechanism to automatically identify dangerous states such as unconsciousness and sudden illness, and actively send location and distress signals, providing critical information for emergency rescue and significantly improving the personal safety of inspection personnel.

[0050] During the inspection process, the host computer issues inspection tasks containing preset routes. The terminal automatically compares its current location with the location of the inspection point, and inspection operations are only allowed after reaching the inspection point. After the inspection is completed, the system automatically determines whether there are any missed inspections and guides the system to conduct supplementary inspections. This achieves closed-loop control of the entire process from task issuance, execution, verification to data upload, effectively preventing missed inspections and incorrect inspections caused by human error, and achieving accurate and efficient inspections.
