Abstract: A method is usable to inspect an environmental device includes using a mobile inspection device to collect data of a site where the environmental device is positioned, generating information of changes in the site where the environmental device is positioned based on the data collected by the mobile inspection device, acquiring operation data of the environmental device and information of an initial operation time of the environmental device, and identifying a health state parameter of the environmental device. The health state parameter of the environmental device is identified based on the information of changes in the site where the environmental device is positioned, the operation data of the environmental device, and the information of the initial operation time of the environmental device.

Abstract: A collection device includes an acquisition device, a control device, and a detection device. The acquisition device acquires information inside a space of a target region. The control device sets a detection path for a collection device based on an unreachable region within the space of the target region. The detection device acquires environmental data including environmental data of the unreachable region detected when the collection device moves along the detection path in the space of the target region.

Abstract: A part identification method includes acquiring an image including a part, detecting the image based on a detection model and identifying a type of the part, and determining part information based on the type of the part identified and outputting the part information. The determining the part information based on the type of the part identified includes determining a part in a predetermined region in the image based on the type of the part identified, and determining the part information based on the part determined. The predetermined region includes a planar region or a spatial region.

Abstract: A control method for an environment adjustment device includes acquiring a plurality of environment parameters at different positions in a room, determining an environment parameter distribution model based on the plurality of environment parameters at the different positions, and determining a plurality of environment parameters corresponding to located positions of a plurality of users based on the environment parameter distribution model. The control method further includes calculating respective state parameters of the plurality of users based on the plurality of environment parameters corresponding to the located positions of the plurality of users, and determining a state parameter overall value of the users based on the state parameters of the plurality of users. The control method further includes inputting the state parameter overall value into a first prediction model, and outputting a target parameter distribution of the environment adjustment device.

Abstract: A failure identification and handling method includes capturing video including a failure code, identifying the failure code in the video and obtaining an identified failure code, determining failure related information corresponding to the failure code based on the identified failure code and generating display data based on the failure related information, and displaying the failure related information based on the display data. A failure identification and handling system includes an imaging unit, an identification unit, a determination unit, and a display unit. The imaging unit captures video including a failure code. The identification unit identifies the failure code in the video and obtains an identified failure code. The determination unit determines failure related information corresponding to the failure code based on the identified failure code, and generates display data based on the failure related information. The display unit displays the failure related information based on the display data.

Abstract: Systems, methods and devices relating to measuring free chlorine in liquid samples. An enhanced graphite electrode and sensors comprising the same are provided. The enhanced graphite electrode in conjunction with a reference electrode and a counter electrode can be used in a chronoamperometry mode to detect concentrations of free chlorine in liquid samples, especially static liquid samples. The enhanced graphite electrode can also be used in conjunction with a counter/reference electrode in a pulsed amperometric detection mode to detect concentrations of free chlorine in liquid samples, especially static liquid samples.

Abstract: Systems, methods, and devices relating to measuring free chlorine in samples. A graphite based electrode or sensor is provided. In conjunction with a reference electrode, a counter electrode, and a potentiostat, the electrode can be used to detect 2-6 ppm concentrations of free chlorine in liquid samples. The electrode can be manufactured from graphite used in pencil leads by electrochemical modification, with the graphite as the working electrode, and a suitable reference electrode, using an ammonium carbamate based electrolyte.
