  • Patent number: 11480935
    Abstract: There is described a building management system and a method for auto-tagging points. Data associated with multiple points of a site are received, and each point is associated with a point name and a point descriptor. A building name is identified based on the point name for each point by extracting a first part detected frequently among the data associated with the points. A point equipment is determined from a second part of each point name and a point function is determined from a third part of each point name. A set of point tags is generated based on the point equipment, the point function, and the point descriptor. Confidence scores are created for the set of point tags based on matching characteristics to a common tag set.

  • Patent number: 11461605
    Abstract: There is described a building automation system comprising a communication component, a processor, and an output component. The communication component scans the building automation system to discover devices, and the processor generates a visual code for a particular field device. The visual code identifies a uniform resource locator directed to a virtual node hosting environment of the building automation system associated with the field device. The output component produces the visual code at a physical material for exhibition in proximity to the field device. Thereafter, the hosting environment receives a status request, associated with the uniform resource locator, for the field device from a mobile device. The hosting environment generates point information associated with the field device based on information collected from the field device in response to receiving the status request. The communication component sends the point information to the mobile device.

  • Patent number: 11422202
    Abstract: A circuit interrupting device with overload current detection is provided. It comprises a hot conductor, a main contactor and a first electromagnetic device configured to remove power from an electrical circuit when overload current exceeds a predetermined % of a rated load current. It further comprises a section of conductor that generates heat and a thermal overload current detection mechanism including a temperature sensing switch having contacts. The temperature sensing switch closes the contacts when a temperature reaches a predefined temperature threshold corresponding to an overload current, in which case the temperature sensing switch electrically couples power to a second electromagnet which is disposed across the hot conductor and a connection to a neutral conductor. The energized second electromagnet generates a magnetic force capable of moving an armature that unlatches the latch releasing the spring to open the main contactor removing power from the electrical circuit.
