Benefits of technology

The present invention provides a method for checking a group of pressurized-fluid cylinders during use. Each cylinder has a valve with an electronic device that measures pressure inside. The device collects and stores data about the pressure, and an emitter sends the data to a processing system. The method involves simultaneously emitting the same information from all cylinders in the group. The system automatically compares the emitted data to detect any abnormalities in the cylinders. This method helps ensure the safe and consistent use of the pressurized-fluid cylinders.

Problems solved by technology

This is because the checking of cylinders of conditioned gas is subject to safety and industrial efficiency requirements and thereby entails a significant amount of logistic support and labor.
This is a particularly sensitive issue in the medical field where a defective cylinder or a cylinder containing an incorrect mixture may have serious consequences.

Embodiment Construction

[0009]To this end, the invention proposes a method for checking a homogeneous batch of pressurized-fluid cylinders during at least part of the cycle of use of said cylinders, the cylinders each being equipped with a valve provided with an electronic device comprising at least one sensor for measuring the pressure obtaining inside the cylinder, a data storage / acquisition and processing system and an emitter of electromagnetic waves, for example at radio frequency, designed to transmit to a distance at least one of the information items from among: the identity of the cylinder and the pressure measured inside said cylinder, the method involving an emission step in which all the cylinders of the batch emit at least one information item of the same nature when they are simultaneously in one and the same phase of the cycle of use, and a step of comparing the information items of the same nature emitted by the cylinders in order automatically to detect an anomaly in the batch.

Abstract

The invention relates to a method for controlling a homogeneous batch (1) of pressurised fluid cylinders (2) during at least part of the use cycle of said cylinders. According to the invention, each of the cylinders (2) is provided with a valve (3) having an electronic device (4) including at least one sensor (14) for measuring the pressure (P) inside the cylinder (2), a system (44) for storing / acquiring and processing data and an electromagnetic wave transmitter (34), for example using radio frequency, designed for the remote transmission of at least one of the following items of information: the identity of the cylinder (2) and the pressure (P) measured inside said cylinder. The method includes a transmission step in which all of the cylinders (2) in the batch (1) transmit at least one item of information of the same type when they are in the same phase of the use cycle at the same time and a step in which the same-type items of information transmitted by the cylinders are compared for the automatic detection of an anomaly in the batch (1).

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of patent application Ser. No. 12 / 597,902, filed Mar. 27, 2008, which is 371 of International PCT Application PCT / FR2008 / 050536, filed Mar. 27, 2008, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a method for checking a homogeneous batch of pressurized-fluid cylinders.[0003]The invention relates more specifically to a method for checking a homogeneous batch of cylinders of pressurized-fluid, particularly of pressurized gas, during at least part of the cycle of use of said cylinders.BACKGROUND Controlling and monitoring cylinders of conditioned gas during their cycle of use is of key importance on an industrial scale.[0004]This is because the checking of cylinders of conditioned gas is subject to safety and industrial efficiency requirements and thereby entails a significant amount of logistic support and labor. This is a par...
