METHOD FOR CONTROLLING A HOMOGENEOUS BATCH OF PRESSURISED FLUID CYLINDERS

摘要

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).

1. A method for checking a homogeneous batch of pressurized-fluid cylinders during at least part of the cycle of use of the cylinders, the cylinders each being equipped with a valve provided with an electronic device comprising at least one sensor for measuring the pressure (P) obtaining inside the cylinder, a data storage/acquisition and processing system and an emitter of electromagnetic waves designed to transmit to a distance at least one of the information items from among: the identity of the cylinder and the pressure (P) 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.
