摘要:
An implementation is for a two-phase shutoff of a device having a sensor coupled to an integral shutoff system. One example includes a metering system with a sensor coupled to an integral shutoff system, wherein the sensor is used to perform a measurement which indicates that a first threshold has been met, a first response system configured to perform at least one action with respect to receiving the indication that the first threshold was met, the at least one action occurring while the integral shutoff system remains inactivated, a second response system configured to receive an indication from the metering system, wherein the sensor is used to perform a second measurement which indicates that a second threshold has been met, and a second response system configured to perform at least one additional action.

Methods and systems are disclosed herein for accurately calculating battery consumption in a wireless field device. The total current consumed by a radio board associated with a wireless field device can be determined based on the sum of the current consumed as a result of particular events occurring at the radio board. The current consumed by a sensor board of the wireless field device can then be averated with respect to particular type of sensor. The current consumed by the radio board and the current consumed by the sensor board in the wireless field device can be combined to calculate a predictive value indicative of a remaining life of a battery associated with the wireless field device.

A method includes receiving data from multiple wireless field devices using multiple wireless communication protocols. The method also includes normalizing the data from the wireless field devices using one or more templates associated with the wireless field devices. The method further includes transmitting the normalized data in a unified format. The method could also include generating the one or more templates using device description (DD) files associated with the wireless field devices. Each template may provide, for one wireless field device or type of wireless field device, (i) an indication of a type of data provided by the wireless field device or type of wireless field device, (ii) a range of data provided by the wireless field device or type of wireless field device, and (iii) how to normalize data from the wireless field device or type of wireless field device into the unified format.
摘要:
A hybrid slotted time division multiple access (TDMA) and carrier sense multiple access (CSMA) based networks that optimize radio frequency (RF) based network resources, RF infrastructure, and improve network performance in a building which may include time critical sensors, such as smoke sensors, and non-critical sensors. The present system may classify critical sensors as guaranteed sensors which get TDMA slots assigned by a network manager. The non-critical sensors may operate in non-guaranteed CSMA slots but within a predefined latency interval. The present system may provide for both types of sensors to co-exist in tandem within the same wireless network.
