Controllers that control a building's state functions can be controlled by a master controller that the controllers choose themselves. The master controller communicates with the controllers and sensors to determine when a building state should change. When the building state should change, the master controller or another controller determines the device or devices that need to modify state values of the building, and send messages to the devices so that they can change building state. If the master controller has a fault, the working controllers can choose another master controller. When a sensor indicates that a building state needs to be changed the master controller determines which device should change state, then tells the controller that is attached to the device.

Provided are a method and a system for a slag thickness detection and a slag-adding prediction. The method includes: acquiring real-time measurement data and real-time auxiliary data of a slag point on a surface of a protective slag layer of a casting mold; calculating a real-time slag thickness value corresponding to the slag point by using the real-time measurement data and the real-time auxiliary data of the slag point; and predicting a location on the surface of the protective slag layer where a slag-adding is to be performed and a slag-adding time when the slag-adding is to be performed based on a change in the real-time slag thickness value corresponding to the slag point by taking a preset slag thickness value as a reference.

A human-machine interface (HMI) development system analyzes a P&ID drawing of an industrial system to identify equipment and the lines or links between the equipment, and generates an HMI application for visualizing the process carried out by the automation system based on results of this analysis. After identifying the items of equipment represented in the P&ID drawings, the development system allows the user to select equipment of interest to be included on an HMI display being developed. The system can then identify lines (e.g., piping) between the selected items of equipment, and generate an HMI interface display comprising graphical objects representing the selected equipment and the lines between the equipment. As part of this translation, the development system can redraw the lines between the items of equipment in order to simplify the connections relative to their original representations on the P&ID drawings.

A facility providing systems and methods for demand control ventilation for a building, or a portion/portions thereof, using a combination of scheduling and environment sensors for fallback is disclosed. The facility for demand control ventilation modulates the volume exchange of outside air into an enclosed space (i.e., air that is external to the enclosed space) by mechanical air conditioning equipment or ventilation system, such as a fan, a Heating, Ventilation, and Air Conditioning (HVAC) system, and so on. Demand control ventilation is used not only to ensure that people within buildings have an allotted amount of fresh air but also to provide a cost savings to users, as a lower amount of airflow can reduce energy use and, therefore, energy costs.

A luminaire for lighting and for distribution of conditioned air within a space includes a housing having a lighting element, a duct opening, and at least one air vent coupled to the duct opening. The at least one air vent is configured to deliver conditioned air to the space. A method of controlling light and conditioned air delivery within a space, by a single combined lighting and conditioned air fixture, includes providing control and power signals to a controller coupled to the single combined lighting and conditioned air fixture, controlling lighting functions via the controller, and controlling conditioned air functions via the controller.

Disclosed are a method for searching a cross-regional power supply area based on a common information model (CIM) and a system thereof. In the method, a hash function is first created according to a size of a power grid in which a power source is located; identification numbers of all devices in the power grid are mapped to a discrete hash table according to the hash function, and a collision is solved by using separate chaining; and a hash topological graph of the power grid is formed by using the discrete hash table; and a power supply area of a designated device is searched by using the hash topological graph. According to the present invention, devices in a power supply area are located rapidly and accurately by creating a discrete hash table for all device resources, so that the amount of computation is greatly reduced, and the efficiency of searching the power supply area is significantly improved.
