Abstract

The invention relates to a barometer displaying the atmospheric pressures measured over a chosen length of time by means of a curve. It consists of a casing (1) having a screen (2) and one or more buttons (3) or (4). When the user pushes the "week" button, for example, a curve is displayed on the screen, giving him the average values of the atmospheric pressure measured throughout the week. If he presses on the "day" button, it is the curve of the pressures measured during the day which will be read on the screen. The device according to the invention is particularly intended for predicting future atmospheric pressure, and therefore what the weather will be like, as a function of the measurements carried out over a chosen length of time.

Description

"Baromètre électronique à affichage des pressions atmosphériques suivant une courbe"."Electronic barometer with display of atmospheric pressures along a curve".

L'invention concerne un baromètre affichant les pressions atmosphénques relevées sur une durée de temps choisie au moyen d'une courbe, afin d'évaluer la tendance dépressionnaire ou anticyclonique.The invention relates to a barometer displaying the atmospheric pressures recorded over a period of time chosen by means of a curve, in order to evaluate the depression or anticyclonic tendency.

Les baromètres actuels se contentent de donner la valeur de la pression atmosphérique au moment présent a l'aide d'un moyen mécanique sur un cadran ou un curseur. Pour évaluer le temps qu'il fera, il faut donc se souvenir du résultat de la mesure effectuée auparavant, et encore cela ne donne que deux points de comparaison.Current barometers are content to give the value of atmospheric pressure at the present time using mechanical means on a dial or a cursor. To assess the weather, it is therefore necessary to remember the result of the measurement carried out before, and again this gives only two points of comparison.

L'invention a pour but de remédier à ces inconvénients en mettant, automatiquement par un moyen électronique, les mesures de pression atmosphérique, effectuées suivant un rythme réguliers en mémoire, afin de pouvoir les consulter, dans une plage de temps choisie, sur un écran à cristaux liquides, sous la forme d'une courbe comme sur la figure 1. The object of the invention is to remedy these drawbacks by automatically storing atmospheric pressure measurements, carried out at a regular rate, in electronic memory, in order to be able to consult them, within a chosen time range, on a screen. liquid crystal, in the form of a curve as in Figure 1.

Le baromètre électronique, selon l'invention, représenté sur la figure 2, se compose d'un boîtier ( soit à poser, soit à accrocher au mur, dont la forme et le matériau peut varier pour lui donner un aspect esthétiqu; d un écran graphique (2) å cristaux liquides, affichant la courbe des mesures de pression atmosphérique relevées pendant une semaine en appuyant sur le bouton (3), ou pendant une journée en appuyant sur le bouton (4).The electronic barometer, according to the invention, shown in Figure 2, consists of a box (either to place or to hang on the wall, whose shape and material can vary to give it an aesthetic appearance; d a screen liquid crystal graph (2), displaying the curve of the atmospheric pressure measurements taken for a week by pressing the button (3), or for a day by pressing the button (4).

La mesure de la pression atmosphérique est faite par une capsule anéroïde classique(1). Son mouvement est amplifié par une démultiplication mécanique(2), par =mpie à engrenages, ou par leviers. Un capteur de position(3) délivre un courant électrique, en fonction de l'amplitude du mouvement de la capsule anéroid Les valeurs de ce courant sont transformées en informations numenques. Une horloge(4 > donne, suivant une durée de temps choisie, l'ordre de stocker dans une mémoire(5) ces informations. numériques. Un compteur(6) vide le premier étage de la mémoire, afin de ne conserver que les dernières valeurs, Un calculateur(7) détermine la moyenne de toutes les valeurs contenues dans la mémoire(5) et tes stocke dans la mémoire(8) suivant une durée de temps choisie. A la demande de l'utilisateur, les valeurs contenues dans la mémoire(8) sont converties en une courbe par le calculateur(9), et cette courbe est lue sur l'écran à cristaux liquides; The atmospheric pressure is measured by a conventional aneroid capsule (1). Its movement is amplified by a mechanical reduction (2), by = mpie with gears, or by levers. A position sensor (3) delivers an electric current, as a function of the amplitude of movement of the aneroid capsule. The values of this current are transformed into digital information. A clock (4> gives the order, according to a chosen duration of time, to store this digital information in a memory (5). A counter (6) empties the first stage of the memory, so as to keep only the last values, A computer (7) determines the average of all the values contained in the memory (5) and stores them in the memory (8) according to a chosen duration of time. At the request of the user, the values contained in the memory (8) are converted into a curve by the computer (9), and this curve is read on the liquid crystal display;
