Definitions

  • This invention relates to monitoring systems for monitoring the operation of a device, and more particularly to a sensor plug for mounting sensors for use with such monitoring systems and a method and apparatus for detecting oil level in the device.
  • the monitoring system 100 may function as a stand-alone unit in which the processing unit indicates the operating conditions of the gearbox through an indicator, for example, indicator 149.
  • the indicator 149 may include one or more light-emitting diodes (LEDs) or a liquid crystal display (LCD) to indicate one or more status levels of the gearbox, such as "POWER ON", “NORMAL”, “CAUTION” or “WARNING".
  • the indicator may include a CRT displaying a graphical user interface (GUI) of the LCD may display the GUI.
  • GUI graphical user interface
  • the processing unit 140 may be pre-programmed with a set of instructions for carrying out at least some of the steps shown in FIG. 9.
  • the oil pressure is sensed.
  • the oil pressure sensor may be placed in any suitable housing, or no housing at all, provided that the oil pressure sensor can sense static oil pressure ("head") within the gearbox.
  • the oil level is determined based on the oil pressure. Oil level monitoring may be performed to detect oil loss due to a variety of reasons.
  • the pressure sensor 162 used in the example described herein is a differential pressure sensor, rather than subtracting the atmospheric pressure (P A ), a direct comparison may be made between the sensed pressure (P) and the desired pressure (P D ). If the sensed pressure (P) is greater than the desired pressure (P D ), a clogged breather element may be indicated.
  • the processing unit 140 may indicate when to change the oil in the gearbox. This may be accomplished by determining the amount of time that the gearbox has been operating since the previous oil change.
  • the frequency axis is evaluated such as:

Abstract

L'invention concerne un bouchon capteur conçu pour détecter une pluralité de conditions de fonctionnement d'une boîte de transmission. Ledit bouchon comprend un corps qui définit un axe. Une extrémité de sonde, formée à une extrémité du corps, est particulièrement conçue pour se fixer à un bouchon de vidange d'huile de la boîte de transmission. Plusieurs capteurs, placés à l'intérieur du corps, sont destinés à détecter des conditions de fonctionnement de la boîte de transmission à travers l'extrémité de la sonde. Des exemples de capteurs placés à l'intérieur du corps sont notamment un capteur de vibrations, un capteur de température et un capteur de pression. L'invention concerne en outre un procédé et un appareil permettant de déterminer une quantité d'huile dans le réservoir d'huile d'un dispositif tel qu'une boîte de transmission. Le procédé et l'appareil consistent notamment à détecter, à l'aide d'un capteur de pression, la pression d'huile statique dans le réservoir. On peut ensuite convertir ladite pression en niveau d'huile et déterminer si ledit niveau est adéquat. On peut également, à l'aide du procédé et de l'appareil, détecter si l'élément reniflard est obstrué, ce qui indique un état de fuite d'huile potentielle. On peut avantageusement installer le capteur à l'intérieur du bouchon de vidange d'huile de la boîte de transmission. La modernisation de boîtes de transmission existantes ou la fabrication de nouvelles boîtes de transmission peut donc être aisément réalisée.
