Definitions

  • the invention relates to a device for measuring pressures, temperatures, impulses, strains and other values in and on hose lines during operation. This is particularly the case with hose lines that are exposed to a wide range of stresses and / or whose unexpected failure can have serious consequences.
  • the hose line has at least one measuring unit which is connected to the hose wall and has at least one sensor for each value to be measured, a transponder and an antenna for wireless data transmission to an external evaluation unit.
  • the most important values to be measured are those that influence the service life of the hose line. These are initially the pressure and the temperature of the medium that is in the hose line and loads the wall. The medium often also loads the hose line with pulses, the level and frequency of which are decisive for the magnitude of the stress on the hose line. Such and other stresses cause the wall of the hose line to give way over time, so that stretches up to bulges occur, which should also be determined.
  • the measuring device allows such stresses as well as their frequency and strength to be determined. If this is known, the aging of the hose line can be estimated and a point in time at which an exchange is necessary in an economical manner, but also in good time before the hose line is burst. The stresses due to the wireless data transmission can be determined even in narrow, difficult to access or dangerous areas as well as on hose lines that change their location during operation.
  • the evaluation unit can be mobile or stationary. Their recordings also enable later research into the causes of many events that have occurred not only in the area of the hose line, but also at other points in the system.
  • the measuring unit and its individual parts are of such small dimensions that they can certainly be arranged within the wall of a hose line, for example by vulcanization.
  • the small dimensions of the measuring unit allow it to be arranged on the outer surface of the hose line, where it can be protected, for example, by a sleeve that has been pushed on.
  • the pressures, temperatures, impulses and strains to be measured and ascertained are transmitted proportionally to the outer surface of the hose line and can therefore also be removed there.
  • the transponder is designed as a smart transponder. Then the measurement data supplied by the sensor or from the sensors are not only stored in the transponder and output in the stored form until output to the external evaluation unit, but the measurement data can then be processed or evaluated even before they are output in the transponder.
  • the memory of such a transponder also makes it possible to obtain reliable and long-term information about the hose line in question in an inexpensive manner.
  • the measuring unit has a special data memory. It can then be used to store even more measurement data, so that a larger number of sensors can be used. The measurement data can then also be taken from the evaluation unit at larger time intervals.
  • the measuring unit can be equipped with at least one battery or an accumulator. Such a current source enables a higher performance of the entire device, but in particular of the transponder. A larger distance between the measuring and evaluation unit is then also possible.
  • the measuring unit can also be equipped with a measuring transducer. Such a transducer transforms the signals coming from the sensor or sensors so that they can be stored directly either in the memory of the transponder or in the special data memory.
  • Figure 1 is a hose line with measuring device, partially in longitudinal section.
  • Figure 2 shows a detail "A" of Figure 1 schematically and on a larger scale
  • Fig. 3 shows a detail at "B" of Figure 2 also schematically and on an even larger scale.
  • a hose line 1 has at its two end sections a fitting 2, 2a, which is mechanically fixed by means of a socket 3 and firmly crimped to the outside with a hydraulic hose 4 in a pressure-tight manner.
  • a measuring unit 6 is arranged on the outer surface of the hydraulic hose 4, and is firmly connected to the outer surface 5, for example by gluing.
  • a sleeve 7 pushed over the measuring unit 6 protects it.
  • the measuring unit 6 clearly shown in FIG. 2 has a sensor 8, for example for measuring pressure. However, several sensors and sensors for measuring other values can also be provided.
  • a battery or an accumulator 9 supplies the measuring unit with current.
  • FIG. 3 shows the circuit board 11 with the connecting lines 12.
  • a smart transponder 13, a data memory 14 and a measuring transducer 15 are arranged on the circuit board 11 and are connected to one another in the required manner via only schematically indicated conductor tracks 16.

Abstract

L'invention concerne un dispositif permettant de mesurer des pressions, des températures, des impulsions, des dilatations et d'autres valeurs de conduites en tuyaux souples ou à l'intérieur desdites conduites. Pendant que ces conduites sont en service, une unité de mesure est placée dans la conduite concernée ou sur sa paroi avec laquelle elle est solidarisée de manière fixe. Ce dispositif comprend en outre un détecteur pour chaque valeur de mesure, un transpondeur et une antenne pour transmettre des données sans fil des valeurs mesurées à une unité d'évaluation extérieure.
