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).
Abstract:
The invention relates to a method for controlling an electronic pressure gauge for measuring the pressure (P) inside a pressurised gas container, particularly a pressurised gas cylinder, said pressure gauge (1) including: at least one pressure sensor (14); an electronic unit (44) designed to acquire, store and process data; and at least one information device (34) capable of transmitting at least one item of information (P). The method includes: at least one step in which the pressure (P) in the container is measured by the pressure sensor (14); and a step comprising the automatic modification of the operating mode of the pressure gauge (1) and/or the information (P) transmitted by the pressure gauge (1) in order to adapt the operating mode or the information (P) to the current operating status (A, B-C, D) of the container from among a plurality of pre-defined operating statuses (A, B-C, D), said operating statuses (A, B, C, D) being pre-defined by pre-established reference pressure threshold values (S1 to S3) and chronologically linked so as to form a chronological cycle. According to the invention, the aforementioned modification step is performed following the detection of a transition from a first operating status (A, B-C, D) to a second operating status, i.e. when the pressure values (P) measured during the first operating status and compared to the pre-established reference pressure threshold values (S1 to S3) match the second operating status and the second operating status is the next status in the chronological cycle. The invention is characterised in that the pre-defined operating statuses (A, B-C, D) are linked chronologically in a closed-loop chronological cycle and the pressure gauge (1) is connected to the container and can measure the pressure inside the container during the entire closed-loop chronological cycle.

The pressure gauge also includes a first radio (34) with a reception port, said first radio (34) being connected to the electronic unit (44) so as to receive external data (D) in order to modify the operation or the configuration of the pressure gauge (1). The reception port of the first radio (34) is designed to read data modulated in terms of the frequency and/or intensity of an external magnetic field at a first low frequency, for example a frequency between 50 and 300 KHz. The first radio includes a first radio transmission port connected to the electronic unit (44) in order to transmit information (P) from the pressure gauge (1). The first transmission port and the reception port of the first radio (34) have a substantially identical transmission and reception operating frequency. The invention is characterised in that it includes a second radio (340) having only a transmission port, said second radio (340) being connected to the electronic unit (44) for the wireless transmission of information (P), in particular information relating to the operation of the pressure gauge (1). The transmission port of the second radio (340) is designed to transmit data by modulation of frequency and/or intensity of a magnetic field at a second high frequency, above the first frequency of the first radio (34), for example between 300 KHz and 800 MHz.

The invention relates to a tap (1) for a pressurized gas cylinder, that comprises a body (2) to be connected to a gas (G) outlet opening (3) of a gas cylinder (4), un gas (G) off-take circuit (C) including at least one gas outlet (5, 25), at least one valve (6) movable between a circuit (C) closing position and a circuit (C) opening position, at least one member (23) for adjusting the release flow of the gas (G), and a single actuation member (9) capable of interaction both with the valve (6) and with the flow adjustment member (23), characterized in that the actuation member (9) is mounted so as to be movable relative to the body (2) according to two distinct movements, said actuation member (9) being arranged relative to the valve (6) and the flow adjustment member (7) so that the two types of movements respectively control the movement of the valve (6) between the opening and closing positions on the one hand and the flow adjustment member (23) on the other hand. The invention can be used as a tap with a built-in expander for a pressurized gas cylinder, e.g. pressurized oxygen in particular for oxygen therapy in medicine.
