Industrial innovation! Technical solution of British gas shield combustible gas sensor in robotic dog

Industry background:

The production, storage, and transportation processes in chemical plants involve a large amount of flammable and toxic gases. Traditional manual inspections suffer from pain points such as low efficiency, inaccessibility to personnel in high-risk areas (confined spaces, storage tank areas, high-temperature and high-pressure zones), difficulty in tracing inspection trajectories, and delayed detection of potential hazards, which can easily lead to safety accidents such as gas leaks and explosions. To address these challenges, relying on the high-precision detection capabilities of British Qidun flammable gas sensors, combined with the autonomous movement and flexible inspection abilities of robotic dogs, and paired with GPRS positioning technology, an integrated solution of "intelligent inspection + precise detection + remote control" is created. This solution achieves full-area, no-dead-angle, and all-weather gas monitoring in chemical plants, replacing manual high-risk inspections, improving safety control efficiency, reducing safety risks, and assisting enterprises in compliant production.

Core Objective: With the British QiDun combustible gas sensor as the detection core, integrating a robotic dog mobile platform, to achieve precise detection, real-time positioning, remote alarming, and data tracing of combustible gases and toxic and hazardous gases. This covers high-risk areas that are difficult to reach through manual inspection, reduces manual input, eliminates inspection blind spots, ensures production safety and personnel safety in chemical plants, and meets compliance requirements such as the "Safety Code for Special Operations in Hazardous Chemical Enterprises" and "Ambient Air Quality Standards".

Integrated scheme design

This solution adopts a "modular integration" design, deeply integrating the British Gas Shield UGT-C5 combustible gas sensor, GPRS Beidou positioning module, and intelligent inspection robotic dog to ensure the coordinated operation of all components. The specific integration design is as follows.

Technical solution for integrating combustible gas sensor into robotic dog

1. Hardware integration: Install the British QiDun UGT-C5 combustible gas sensor at the front end of the robot dog's head to ensure that the detection probe is unobstructed and can quickly capture the surrounding gas concentration. The positioning module is integrated inside the robot dog's body, linked with the sensor and the robot dog control system, to achieve synchronous collection and transmission of location information and detection data. The robot dog's body is equipped with a high-definition camera, which can simultaneously capture images of the inspection area. Combined with gas detection data, it achieves dual control of "visualization + precise detection".

2. Software Integration: Establish data interfaces between sensors, robotic dogs, positioning modules, and remote control platforms to achieve real-time data synchronization. Optimize alarm logic, set up two-level alarm thresholds for low and high alarms. When gas concentration exceeds the threshold, the robotic dog's audible and visual alarms, remote terminal push notifications, and platform pop-up alerts are simultaneously triggered to ensure timely detection by management personnel. Support autonomous planning of robotic dog inspection paths, and focus on setting inspection points based on high leakage areas to enhance inspection efficiency.

3. Linkage control: When the sensor detects an excessive gas concentration, the robotic dog automatically stops patrolling, locks the alarm point, simultaneously captures on-site images, and uploads them to the management platform. Management personnel can remotely control the robotic dog through the platform to approach the alarm point for further precise detection, while dispatching on-site personnel equipped with portable detection devices to the scene for disposal. If the concentration continues to rise, the platform can be linked to the central control system of the chemical plant to trigger ventilation, cut off the gas source, and other linkage operations, forming a complete safety protection loop.

Application scenarios and inspection process

(I) Application Scenario

1. High-risk areas: enclosed spaces (underground utility tunnels, sewage wells, interiors of reaction vessels), storage tank areas (flammable gas storage tanks, hydrogen storage tanks), high-temperature and high-pressure workshops, areas with dense pipelines, and other areas that are inaccessible to humans or have high inspection risks;

2. Conventional areas: chemical production workshops, hydrogen refueling stations, gas transmission pipelines, valve interfaces, inspection passageways, etc., to achieve comprehensive inspection coverage without any dead zones.

(II) Standard inspection process

1. Path planning: Management personnel, through the remote control platform, preset the inspection path, inspection time, and inspection frequency of the robotic dog based on the production layout of the chemical plant and high-risk leakage points, and identify key inspection areas;

2. Autonomous inspection: The robotic dog conducts autonomous inspection according to the preset path. The British Qidun combustible gas sensor detects the concentration of combustible gases in the surrounding area in real time, while the positioning module simultaneously collects location information, and the data is uploaded to the control platform in real time;

3. Abnormality Handling: If the gas concentration is detected to be excessive, the robotic dog will immediately trigger an alarm, lock the alarm point, and upload the on-site images and detection data. Upon receiving the alarm, management personnel can remotely view the on-site situation, dispatch personnel for handling, and simultaneously control the robotic dog for further precise detection;

4. Inspection traceability: After the inspection is completed, the platform automatically stores inspection data, trajectory information, and alarm records. Reports can be exported, facilitating management personnel to verify the effectiveness of the inspection, ascertain inspection responsibilities, and provide a basis for compliance verification;

5. Operation and maintenance support: When the robot dog runs low on battery, it can autonomously return to the charging base station; the combustible gas sensor undergoes regular intelligent calibration, and the platform alerts management personnel for maintenance, ensuring long-term stable operation of the equipment.
