Abstract: A data collection device and method for determining a backflow condition in a water distribution system. The data collection device receives a first data communication from a first node, the first data communication indicating a first possible backflow condition at the first node. The data collection device receives additional data communications from one or more second nodes, the additional data communications indicating backflow conditions at the second nodes. The data collection device aggregates and analyzes the first data value and the additional data values and determines that an actual backflow condition exists based on the aggregated data values and a known relationship between the first node and the second nodes. The data collection device may then perform action(s) in response to determining the backflow condition, such as reporting the backflow condition, requesting updated reporting from the nodes, closing appropriate valves, initiating pumps to increase water pressure, flushing the system, etc.

Abstract: Techniques for managing pedestrian and vehicular congestion are described herein. In an example, a congestion event at a location is identified. The congestion event may be a sporting event, entertainment event, road construction event, etc. A primary route to or from the congestion event is identified. In examples, a primary route conveys traffic to the location, and may be associated with commencement of the event. Alternatively or subsequently, a primary route conveys traffic away from the location, and may be associated with a conclusion of the event. A secondary route that could lessen traffic of the primary route is identified. In a first example, durations of vehicle traffic lights and pedestrian walk/don't walk signs are adjusted to encourage and to increase usage of the secondary route. In a second example, the secondary route is promoted by updating digital signage to send traffic on the secondary route.

Abstract: A data collection device and method for determining an alternative event condition is presented. The method includes receiving a first data communication including a first data value from a first sensor and determining a first event condition based on the first data value being beyond a predetermined threshold. The method further includes receiving additional data communications including additional data values from one or more second sensors, aggregating the first data value and the additional data values, and determining that the determination of the first event condition is incorrect based on the aggregated data values and a known relationship between the first sensor and the one or more second sensors. The method additionally includes determining a second event condition based on the first data value and the additional data values being beyond the predetermined threshold. An action may then be performed in response to the determination of the second event condition.

IPC: G01F25/00
Abstract: Techniques for using data indicating if a gas regulator supplying gas at a regulated pressure to a gas meter (e.g., the gas meter of a house or business) within a gas distribution system has one or more lock-up failure events or venting events, wherein gas is vented to the atmosphere. The data may identify the identity of gas regulators at which the lock-up failure events or venting events occurred. Based at least in part on the identified gas regulators, a number of gas regulators having at least one of lock-up failure events or venting events that are connected to a same gas supply line may be identified. If the number of gas regulators having at least one of lock-up failure events or venting events on the identified gas supply line exceeds a threshold number this may indicate the presence of debris in the gas supply. Remedial steps may be taken, and the situation may be monitored and reassessed.

Abstract: Device(s) and techniques determine if a gas regulator supplying gas at a regulated pressure to a gas meter (e.g., the gas meter of a house or business) within a gas distribution system has one or more lock-up failure events or venting events, wherein gas is vented to the atmosphere. In an example, a sensor obtains information indicating a relative position of a stop stem of a gas regulator and a diaphragm pin of the gas regulator. As pressure increases within the regulator, the diaphragm pin moves toward and/or touches the stop stem. The gas pressure increase may result from debris in the regulator that prevents a valve from fully closing. A signal may be sent from the regulator and/or associated gas meter. The signal may contain information based at least in part on data from the sensor, and which may indicate a lock-up failure event or a venting event by the gas regulator.

Abstract: Techniques detect a low gas-pressure condition within a region without the use of pressure sensors. In an example, gas usage at a service site is disaggregated to show use by individual appliances. A flowrate of gas at an appliance (e.g., a gas hot water tank) having a generally fixed-rate of gas-consumption is determined. Based at least in part on the flowrate of gas at the appliance, and an historical gas flowrate at that appliance, it is determined if gas pressure at the service site is lower than expected. In an example, failure of the appliance to use its typical fixed-flowrate may indicate low gas pressure at the service site. Information is obtained from a second gas meter at a second service site. Based on the gas pressure at the first and second service sites being lower than expected, a low gas pressure situation may exist in a regional area.

Abstract: Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

Abstract: Techniques determine if a gas service (e.g., piping and/or meter) is undersized for the customer's needs. In one example, flowrate information corresponding to gas usage at a service site over a first period of time is obtained. The flowrate information is disaggregated to determine an expected flowrate associated with each of two or more appliances having generally fixed-rates of gas consumption. Flowrate information is again obtained, corresponding to a second period of time. The second flowrate information is compared to one or more combinations (i.e., summations) of the expected flowrates associated with each of the two or more appliances. Based on the comparison, it may be determined that the service site is not appropriately sized. In an example, failure to detect two fixed-rate of gas-consumption appliances operating at their respective fixed-rates at the same time may indicate that the service cannot provide gas at a sufficient flowrate.
