Definitions

  • the present invention is generally related to equipment metering/monitoring systems and methods. More particularly, the present invention relates to a system and method that can monitor and display cumulative and noncumulative, resettable service hours for equipment as well as providing data associated with incremental amounts of equipment usage (e.g., hours, days, etc.). Furthermore, the present invention relates to systems and methods for externally interfacing with metered equipment to determine usage.
  • Metering devices have generally been used to monitor the ongoing duration that equipment has been in use. For example, hour meters are known to be used to monitor the total number of hours that an airplane, tractor or generator has been in use, similar to how an odometer keep track of the number of miles or kilometers that a automobile has been driven.
  • the present inventor has recognized that it would be useful if system and methods providing usage monitoring capabilities for all eletromechanical equipment that would enable equipment managers to more effectively plan maintenance and replacement/salvage activities for previously un-monitored equipment such as rentable carpet cleaners, and also provide methods and systems for managing data.
  • systems and methods are described that permit the recording and monitoring of cumulative as well as incremental usage (e.g., incremental and resettable service periods associated with equipment rental periods) for equipment.
  • Usage of metered equipment can be measured as units including hours, days, weeks, months, etc.
  • Service periods can be determined for equipment based on usage data defined by time between specified units of use in a maintenance schedule.
  • a monitoring unit associated with metered equipment can be battery powered and self contained, although it can also be powered from the metered equipment being monitored, at least part of the time.
  • the handheld device could be as simple as a permanent magnet, or as complicated as a microcontroller with a keypad interface and including an electromagnet for coupling with the monitoring unit.
  • a hall effect sensor will be mounted next to a 2 terminal current shunt (or wire) which would sense the presence of AC or DC current to the equipment being monitored as well as sense the presence of a AC or DC magnetic field from a handheld device used by service personnel to read the various records and reset them as desired.

Hand held units are currently available in various forms and with different communication capabilities.

  • a battery powered electromagnet with a switch can also be employed. Because the device can employ a Hall effect sensor, the wand can also radiate AC magnetic fields at one or more frequencies as well as providing DC signals. Additional signals can allow for the setting of the date and time as well as to reset values.

Abstract

L'invention concerne des systèmes et des procédés pouvant être mesurés de l'extérieur et un affichage cumulatif, non cumulatif et lisseur de service effaçable en vue de commander un équipement et fournir des données associées à une somme incrémentale d'utilisation de l'équipement (notamment heure, jour, etc.). L'invention concerne également des interfaces externes de système avec un équipement à compteur afin de déterminer la durée d'utilisation. Les systèmes et les procédés d'utilisation permettent d'enregistrer les unités totales d'utilisation de l'équipement cumulatives, incrémentales et effaçables, telles que les locations d'équipement électromécaniques disponibles au public (notamment les nettoyeurs de tapis), les équipements d'entretien du gazon, les générateurs électriques, et les équipements audiovisuels. Le conteneur monté sur l'équipement (100) peut servir d'enregistreur de données afin de mesurer l'utilisation de l'équipement à compteur. L'unité de commande (110) associée à l'équipement à compteur peut être actionnée par batterie et est autonome. Un dispositif de poche (220) permet de communiquer, d'interroger et de remettre à zéro les fonctions de l'équipement à compteur (100).
