Definitions

  • the field of the invention is management systems, such as irrigation management systems and utility commodity management systems. More particularly, the invention relates to a recording node useful in the receiving, storing, determining and/or sending of inigation information and utility commodity information and to management systems using such a recording node.
  • the recording node can receive data from other devices and send data to other devices in a network process control system.
  • a homeowner typically sets a watering schedule that involves specific run times and days for each of a plurality of stations, and the controller executes the same schedule regardless of the season or weather conditions. From time to time the homeowner may manually adjust the watering schedule, but such adjustments are usually only made a few times during the year, and are based upon the homeowner's perceptions rather than the actual watering needs of the landscape.
  • One change is often made in the late Spring when a portion of the yard becomes brown due to a lack of water.
  • Another change is often made in the late Fall when the homeowner assumes that the vegetation does not require as much watering.
  • These changes to the watering schedule are typically insufficient to achieve efficient watering. Further, the homeowner will likely not change their irrigation practices until they are made aware of how inefficient their watering practices are.
  • More sophisticated inigation controllers use evapotranspiration rates for determining the amount of water to be applied to a landscape.
  • Evapotranspiration is the water lost by direct evaporation from the soil and plant and by transpiration from the plant surface.
  • Inigation controllers that derive all or part of the irrigation schedule from ETo data are discussed in US Patent No. 5,479,339 issued December 1995, to Miller, US Patent No. 5,097,861 issued March 1992 to Hopkins, et al., US Patent No. 5,023,787 issued June 1991 and US Patent No. 5,229,937 issued July 1993 both to Evelyn-Veere, US Patent No.

  • the utility commodity flow data is received, stored and determined by the recording node.
  • the utility commodity information that is received and generated from the calculations is transmitted over the network to the utility commodity provider via the communication node.
  • the utility commodity provider may monitor the utility commodity information on a daily basis or any other time period. A normal utility commodity use pattern may be established over a period of time and if the use exceeds the normal by a set amount then a reminder may be sent to the consumer, step 730.
  • microprocessor 120, Figure 1 would be programmed to provide the information in step 730 directly to the consumer.
  • this information also to the utility commodity provider in addition to the consumer may advantageously increase the likelihood that potential utility commodity flow anomalies will be checked and appropriate steps taken to conect the problem.
  • Sending the information on flow anomalies to the utility commodity provider would especially be beneficial, if the consumer is frequently gone for extended periods of time from his/her residence.
  • the utility commodity provider may use the utility commodity information received from the recording node to bill the consumer, step 740.
  • the recording node receives the water, electricity and gas flow data and transmits it to the appropriate entity so the consumer may be billed for the utility commodity they use. Since only one device is required to obtain the water, gas and electricity flow data and additionally send it to the utility commodity provider, this should result in substantial savings to the providers of these utility commodities, which should result in reduced utility commodity costs to the consumer.
  • Figure 8 is a flow chart of steps involved in the use of the recording node in the accommodating of imposed utility commodity restriction requirements and in the exercising of judicious use of a utility commodity when the utility commodity provider applies a conservation or peak pricing program to the utility commodity.
  • Conservation pricing and peak pricing are used as incentives to get the consumer to reduce total use of a utility commodity or reduce utility commodity usage during a specific time period of the day, respectively.
  • Utility commodity restrictions, conservation pricing and peak pricing could apply to anyone of the three commodities, water, electricity or gas. Although, certain practices are generally used with certain commodities, such as conservation pricing with water and peak pricing with electricity.
  • step 800 the recording node receives, stores and determines utility commodity flow data.
  • step 810 the utility commodity flow data and other information, related to utility commodity usage, are transmitted over the network to the consumers and third parties via the computer node (See Figure 3).
  • step 820 restrictions are imposed on the use of a utility commodity and/or the utility commodity provider initiates conservation or peak pricing programs on the use of a utility commodity.
  • the information on the restrictions, conservation pricing and/or peak pricing are transmitted over the network to the consumer and third parties via the computer node 830.
  • the consumers and third parties Based on the information received the consumers and third parties consider possible changes the consumer might make in their use of utility commodities 840.
  • step 850 the consumer modifies their utility commodity usage practices to accommodate imposed restriction requirements on the use of a utility commodity and/or to achieve the least price impact from the initiation of a conservation or peak pricing program by the utility provider.
  • Some of the changes the consumer may make, in their utility commodity usage may be based on recommendations they receive from third parties, such as, water districts, electricity providers, and so forth 860.

Abstract

L'invention concerne un noeud d'enregistrement (100) sur un site consommateur utilisé pour recevoir, stocker, déterminer et/ou envoyer des informations concernant un produit de services collectifs. Ce noeud d'enregistrement (100) fait partie intégrante de réseaux (370) ou a accès à des réseaux (370) pour recevoir et transmettre des informations. Le noeud d'enregistrement (100) fait partie d'un système (300) de commande de processus en réseau, qui comprend d'autres noeuds, tels qu'une unité de commande (200), un ordinateur (320), un moniteur (330), un affichage (340) et un noeud de communication (360). Ledit noeud d'enregistrement (100) reçoit des données concernant le débit d'écoulement et la pression du produit, ainsi que les facteurs environnementaux ; il mémorise les données, fait des évaluations quant à ces données, et envoie des informations relatives au produit de services collectifs via un réseau (370) aux consommateurs (380) et/ou à des tiers (381). Le produit de services collectifs peut être de l'eau, de l'électricité et/ou du gaz. Les informations que les consommateurs (380) et les tiers (381) reçoivent du noeud d'enregistrement (100) et d'autres noeuds via le réseau (370) les aident à gérer les systèmes fonctionnels .
