Description

Technical Field

[0001] This utility model relates to an unmanned detection system, and more particularly to an unmanned detection system for toxic and harmful gases, belonging to the field of environmental monitoring technology. Background Technology

[0002] With the accelerating pace of global industrialization, the harm posed by various toxic and harmful gases generated during industrial production to humankind has become increasingly serious. Besides the well-known hazards of carbon monoxide and hydrogen sulfide, the health and safety risks of various volatile organic compounds (VOCs) have also received increasing attention. Even previously overlooked or ignored toxic and harmful gases are now infiltrating our daily work and lives, such as indoor air quality and in-vehicle air pollution. Currently, the detection of toxic and harmful gases mainly relies on manual, handheld detectors for on-site testing. This method exposes personnel directly to hazardous environments, posing a serious threat to their health. Furthermore, manual detection is only suitable for environments with normal temperature and pressure; it is unsuitable for high-temperature and high-pressure environments. Therefore, it is necessary to improve existing technologies. Utility Model Content

[0003] To address the safety hazards to testing personnel caused by the existing manual methods for detecting toxic and harmful gases, as well as the inability of testing personnel to enter high-temperature and high-pressure environments, this utility model provides an unmanned detection system for toxic and harmful gases.

[0004] This utility model is achieved through the following technical solution: an unmanned detection system for toxic and harmful gases, including an unmanned vehicle, an on-board controller, an environmental perception sensor, a toxic and harmful gas sensor, a decontamination spraying assembly, a wireless communication device, and a remote controller; The unmanned vehicle is equipped with an onboard controller, environmental perception sensors, toxic and harmful gas sensors, and wireless communication equipment. The onboard controller is electrically connected to the unmanned vehicle, the environmental perception sensors, the toxic and harmful gas sensors, and the wireless communication equipment. A remote controller is remotely connected to the onboard controller via the wireless communication equipment. The remote controller sends route data containing the driving route to the onboard controller and manually controls the unmanned vehicle's movement based on terrain, environment, and image data returned by the environmental perception sensors. The onboard controller receives terrain, environment, and image data returned by the environmental perception sensors and automatically controls the unmanned vehicle's movement based on the terrain, environment, and image data, and sends gas detection data detected by the toxic and harmful gas sensors to the remote controller. The unmanned vehicle is also equipped with a decontamination spraying assembly, which is electrically connected to the onboard controller. This allows the unmanned vehicle to enter toxic and harmful gas sites for detection, replacing traditional manual detection and effectively protecting the lives of detection personnel. The unmanned vehicle can be controlled automatically or manually, effectively improving the automation level of the equipment, reducing labor load, and increasing detection efficiency.

[0005] Furthermore, the unmanned vehicle includes a vehicle body and tracks located on both sides of the vehicle body. The vehicle body houses a battery pack, a power and transmission mechanism, and the environmental perception sensor and wireless communication equipment are located on the top of the vehicle body. A toxic and harmful gas sensor is located at the front of the vehicle body, and a decontamination spraying assembly is located at the rear of the vehicle body. The power and transmission mechanism is connected to the driving track, and the power and transmission mechanism is electrically connected to the vehicle controller. The vehicle controller communicates with the remote controller through a wireless communication device, thereby automatically controlling the unmanned vehicle to drive, or manually controlling the unmanned vehicle to drive through the remote controller. The battery pack is electrically connected to the power and transmission mechanism, the environmental sensing sensor, the toxic and harmful gas sensor, the decontamination spraying assembly, and the wireless communication device, and is used to supply power to the power and transmission mechanism, the environmental sensing sensor, the toxic and harmful gas sensor, the decontamination spraying assembly, and the wireless communication device. This allows the highly mobile tracked unmanned vehicle to penetrate deep into the detection area, ensuring detection accuracy.

[0006] Furthermore, the environmental perception sensors include a lidar, an ultrasonic transducer, a gyroscope, a weather instrument, an inertial navigation system, and a camera. The lidar, ultrasonic transducer, gyroscope, weather instrument, inertial navigation system, and camera are all electrically connected to the battery pack to supply power to these devices. This allows the lidar and ultrasonic transducer to monitor terrain and obstacle data around the unmanned vehicle, the gyroscope and inertial navigation system to enable autonomous navigation without relying on external information, the weather instrument to monitor ambient temperature, humidity, wind speed, wind direction, air pressure, and other meteorological information, and the camera to acquire image data of the vehicle's surroundings for use in both automatic and manual driving.

[0007] Furthermore, the toxic and harmful gas sensor includes a spectral sensor, a chemical resistance sensor, and a sampling port. The sampling port is connected to both the spectral sensor and the chemical resistance sensor and is located at the front of the vehicle body. The battery pack is electrically connected to both the spectral sensor and the chemical resistance sensor to supply power to them. This allows the spectral sensor to analyze the interaction between gas molecules and light waves of a specific wavelength to determine the type of toxic and harmful gas. The chemical resistance sensor reacts with the chemical gas, causing a change in resistance, which in turn determines the gas concentration.

[0008] Furthermore, the vehicle controller includes a processing module, a data storage module, and a self-test module. The processing module is electrically connected to both the data storage module and the self-test module. The battery pack is electrically connected to the processing module, the data storage module, and the self-test module, and is used to supply power to these modules. The processing module is electrically connected to the wireless communication device so that the processing module can use the wireless communication device to communicate with the remote controller, for sending gas detection data to the remote controller and receiving driving route data and control commands sent by the remote controller. The processing module is electrically connected to the environmental perception sensor, so that the processing module can automatically plan the driving path and automatically avoid obstacles based on the terrain, environment, image, weather and other data transmitted back by the environmental perception sensor. The processing module is electrically connected to the toxic and harmful gas sensor so that the processing module compares and processes the concentration threshold data of the toxic and harmful gas detected by the toxic and harmful gas sensor, and transmits it to the remote controller through the wireless communication device. It also automatically plans the driving route and marks the dangerous area based on the chemical gas data detected by the toxic and harmful gas sensor. This allows for the qualitative and quantitative analysis of toxic and harmful gases via an onboard controller, and enables automatic entry and exit from the detection area. The entire detection process is efficient, fast, and safe.

[0009] Furthermore, the decontamination spraying assembly includes a decontamination storage tank located on the top of the vehicle body and a spray pipe located at the rear of the vehicle body. The spray pipe is horizontally located at the rear of the vehicle body and has multiple downward spray nozzles spaced apart on it. The spray pipe is connected to the decontamination storage tank via a pipe with a liquid pump. The liquid pump is electrically connected to the processing module so that the processing module can control the operation of the liquid pump to mark or disinfect the contaminated area.

[0010] Furthermore, the wireless communication device includes a switch, a wireless transmission module, and a network port converter. The environmental perception sensor and the toxic and harmful gas sensor are connected to the network port converter via CAN, RS232, RS485, or ModBus. The network port converter is connected to the switch via Ethernet. The switch is electrically connected to both the processing module and the wireless transmission module, enabling the processing module to communicate with the remote controller using the wireless transmission module. This allows the processing module to send toxic gas detection data and image data of the unmanned vehicle's surroundings to the remote controller, and to receive planned driving route data and manual control signals of the unmanned vehicle transmitted back from the remote controller.

[0011] This invention has the following advantages and effects: Using the above solution, the unmanned detection system possesses functions such as autonomous driving and obstacle avoidance, detection, real-time data transmission, manual / automatic switching, high-precision positioning, path planning, and efficient data storage and management.
