Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and particularly to an indoor air detection and alarm device based on artificial intelligence. Background Art

[0002] With the progress of artificial intelligence technology, intelligentization has become the development trend of the electronic information industry. How to achieve on-site or remote intelligent control of air quality monitoring devices has become a hot research topic. In the prior art, an air quality monitoring and alarm system based on artificial intelligence generally includes two parts: an artificial intelligence analysis and alarm system and a quality detection system. For some simple monitoring scenarios, there are various implementation forms in the prior art.

[0003] In existing large warehouses, due to their large area, there are sometimes many separate isolation areas. When using traditional air quality detection equipment, multiple devices need to be configured. Moreover, limited by the functions of a single air quality detection device, which are often not comprehensive enough, managers also need to configure air quality detection devices with specific functions for some local or specific areas. These factors lead to a geometric increase in the difficulty and cost of air quality collection management as the area expands, while centralized configuration and management of warehouses are the future trend. Please refer to Figure 1 and Figure 2 , in the prior art, there is an air quality comprehensive detection and alarm device for warehouses, which includes multiple air collection units (11), a mobile channel (12), and an air detection management center (13). After each air collection unit (11) injects the collected air sample into an airbag (14), the airbag (14) is sent through the mobile channel (12) to the air detection management center (13) for detection. It can be applied to air quality detection scenarios in medium and large warehouses. However, when the air detection management center (13) conducts air quality detection, it needs to use a manipulator (15) in cooperation with a visual recognition unit (16) to find the inflation head on the airbag (14) clamped by the airbag capture unit (17), and insert a needle (18) from the inflation head to extract air for detection. This part of the air extraction and detection mechanism has a complex structure and high cost. Moreover, the degrees of freedom and movement space of the manipulator are limited, and the situation where the position of the inflation head exceeds the movement space of the manipulator may occur, resulting in the inability to smoothly extract air for detection. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an indoor air detection and alarm device based on artificial intelligence to at least partially solve the problems existing in the prior art.

[0005] The present invention is achieved through the following technical solutions:

[0006] An indoor air detection and alarm device based on artificial intelligence, comprising an air detection management center, a mobile channel, and at least one air collection unit. The air collection unit is communicatively connected to and controlled by the air detection management center. One end of the mobile channel is provided with a blower, and the other end of the mobile channel is communicated with the air detection management center;

[0007] The air collection unit includes a base communicated with the mobile channel. The base is provided with a collection head, an inflation unit, an airbag storage unit, and a loading and unloading mechanism. The inflation unit is used to inflate the gas sucked from the collection head into the airbag. One end of the airbag is provided with a guiding portion, and the guiding portion protrudes from the outer wall of the airbag. The loading and unloading mechanism can send the airbag in the airbag storage unit to the inflation unit for inflation, and send the inflated airbag into the mobile channel and make the guiding portion face the air detection management center;

[0008] The air detection management center is provided with an airbag positioning and fixing device, a needle inserting device, an air quality detection unit, a control unit, and an alarm unit. The blower can blow air to make the airbag in the mobile channel move and make the guiding portion of the airbag insert into the airbag positioning and fixing device. The needle inserting device can insert an exhaust needle into the corresponding airbag from the guiding portion inserted into the airbag positioning and fixing device. The exhaust needle is communicated with the air quality detection unit. The air quality detection unit is communicatively connected to the control unit and the alarm unit. The control unit can control the blower, the airbag positioning and fixing device, and the needle inserting device.

[0009] Further, the airbag positioning and fixing device is provided with a guiding surface, a limiting hole, and an openable and closable fixing clip. The guiding surface and the limiting hole are arranged in cooperation with the guiding portion. The guiding surface is conical, the flared end of the guiding surface faces the connection port of the mobile channel and the air detection management center, the closed end of the guiding surface is opened to form the limiting hole, and the fixing clip is arranged at the end of the limiting hole away from the mobile channel. The fixing clip can clamp the guiding portion inserted into the limiting hole.

[0010] Further, the airbag positioning and fixing device includes a guiding cover in the shape of a conical barrel. The inner side wall of the guiding cover is set as the guiding surface, and the small end opening of the guiding cover is set as the limiting hole.

[0011] Further, the airbag positioning and fixing device further includes a support cylinder with openings at both ends and a first rotation driving device. The support cylinder is rotatably arranged in the air detection management center. The first rotation driving device can drive the support cylinder to rotate, and make one end of the support cylinder face the connection port between the mobile channel and the air detection management center, or make this end of the support cylinder face the ground. The guiding surface and the limiting hole are arranged inside the end of the support cylinder away from the mobile channel.

[0012] Further, the first rotation driving device is a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod. One end of the first rotation driving device is hinged to the support cylinder, and the other end of the first rotation driving device is hinged to the frame that rotatably mounts the support cylinder.

[0013] Further, the needle inserting device includes a slider and a sliding driving device. The slidable direction of the slider is arranged facing the limiting hole. The exhaust needle is fixedly arranged on the slider facing the limiting hole. The sliding driving device can drive the slider to slide back and forth close to or away from the limiting hole.

[0014] Further, the sliding driving device is an electric telescopic rod.

[0015] Further, a first magnetic attracting member is further arranged inside the guiding portion of the airbag. The airbag positioning and fixing device further includes a second magnetic attracting member. The second magnetic attracting member is arranged on the side of the fixing clip away from the limiting hole in cooperation with the guiding portion. The second magnetic attracting member can generate a magnetic attraction force on the first magnetic attracting member when the guiding portion is inserted into the limiting hole.

[0016] Further, the length of the airbag after inflation is greater than the inner diameter of the mobile channel. The guiding portion is arranged at one end in the length direction of the airbag.

[0017] Further, there are two guiding portions provided on the airbag. The two guiding portions are respectively arranged at opposite ends of the airbag.

[0018] The beneficial effects of the present invention are as follows:

[0019] The indoor air detection and alarm device based on artificial intelligence can make the airbag in the moving channel move by blowing air with a fan, and make the guiding part of the airbag insert into the airbag positioning and fixing device. Then, the needle inserting device inserts an exhaust needle into the corresponding airbag from the guiding part inserted into the airbag positioning and fixing device for extraction and detection. The airbag positioning and fixing device positions the airbag, so that the needle inserting device only needs to insert the exhaust needle through a fixed path, thus eliminating the need for a manipulator and vision recognition technology. The structure and control method are simpler, and it can avoid the situation where the needle cannot be inserted due to the limited degrees of freedom and movement space of the manipulator. When the support cylinder rotates to face the connection port between the moving channel and the air detection management center, the airbag can enter the airbag positioning and fixing device under the action of the fan to complete positioning and fixing. When the support cylinder rotates towards the ground, the deflated airbag can slide down under the action of gravity, so that the airbag positioning and fixing device can fix the next airbag. The second magnetic part generates a magnetic attraction force on the first magnetic part to preliminarily fix the airbag, facilitating the fixing clamp to clamp the guiding part to complete the complete fixing of the airbag. The length of the airbag after inflation is greater than the inner diameter of the moving channel, which can prevent the airbag from flipping too much in the moving channel, facilitating the guiding surface to guide the guiding part into the limiting hole to realize airbag positioning. The guiding parts are respectively arranged at both opposite ends of the airbag, facilitating the storage of the airbag on the airbag storage unit without the need to distinguish the placement direction.

[0020] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the following specification. BRIEF DESCRIPTION OF THE DRAWINGS
