DISPOSITIF DE SURVEILLANCE DES CONDITIONS DE CULTURE DES PLANTES DEVICE FOR MONITORING THE CONDITIONS OF CULTIVATION OF PLANTS
La présente invention concerne un dispositif de surveillance des conditions de culture des plantes, en particulier un dispositif de surveillance de l'état réel des plantes par la mesure d'un courant électrique passant dans les The present invention relates to a device for monitoring the growing conditions of plants, in particular a device for monitoring the real state of plants by measuring an electric current passing through them.
nervures des feuilles des plantes.veins of plant leaves.
Pour cultiver des plantes, il est classique de 15 considérer en premier lieu le maintien d'un environnement convenable pour la culture des plantes, par exemple de fournir aux plantes des conditions adéquates de température, d'humidité, de lumière, ainsi que les substances nutritives adéquates, etc... Cependant ces éléments assurent un état de culture des plantes propre à atteindre effectivement l'objectif initial correspondant au désir de l'homme, et on provoque la croissance des plantes par force, en ayant pour but la satisfaction des désirs humains. Contrairement à ce que l'on attend, il est difficile de faire correspondre les conditions 25 respectives mentionnées ci-dessus à leur résultat,selon le procédé classique. Par exemple, au cas o les plantes ne poussent pas dans le sens de l'objectif initial, il est difficile d'établir une correspondance biunivoque entre la cause de ce fait et le résultat. En outre, il s'écoule un laps de temps 30 très long entre l'apparition de la cause et son résultat, et par conséquent, l'établissement de la correspondance est In cultivating plants, it is conventional to first consider maintaining an environment suitable for growing plants, for example providing plants with adequate conditions of temperature, humidity, light, as well as the substances adequate nutrients, etc ... However, these elements ensure a state of cultivation of plants capable of effectively achieving the initial objective corresponding to the desire of man, and plants are caused to grow by force, with the aim of satisfying human desires. Contrary to what is expected, it is difficult to match the respective conditions mentioned above to their result, according to the conventional method. For example, if the plants do not grow in the direction of the initial objective, it is difficult to establish a one-to-one correspondence between the cause of this fact and the result. In addition, a very long time elapses between the appearance of the cause and its result, and therefore the establishment of correspondence is
retardé. Ce sont ces problèmes-là qu'il faut résoudre. delayed. These are the problems that must be resolved.
Un objet de la présente invention est de trouver An object of the present invention is to find
un environnement préférable pour la culture des plantes, à 35 peu près en temps réel. a preferable environment for growing plants, roughly in real time.
Un autre objet de la présente invention est de Another object of the present invention is to
fournir immédiatement aux plantes un environnement préférable. immediately provide plants with a preferable environment.
Les caractéristiques mentionnées ci-dessus et The features mentioned above and
autres avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante, faite en référence au dessin annexé. other advantages of the present invention will appear on reading the following detailed description, made with reference to the accompanying drawing.
- La figure 1 est une vue d'ensemble explicative - Figure 1 is an explanatory overview
d'un mode de réalisation de la présente invention. of an embodiment of the present invention.
En référence à la Figure 1, une paire d'électrodes 2 est insérée dans ou fixée à la nervure la d'une feuille 1 d'une plante et l'on dispose d'un amplificateur 3 et d'un système 4 de sortie. Comme le montre la figure 1, lorsque une paire d'électrodes 2., 2 est insérée dans ou fixée à la nervure la de la feuille 1 d'une plante, avec un intervalle défini au préalable, une tension,correspondant au courant de nervure qui passe dedans, s'établit entre les électrodes 2,2. Le courant de nervure varie suivant l'état de la plante à l'instant considéré. Par exemple, lorsqu'on irradie de la 20 lumière ultraviolette ou infrarouge sur la plante,ou bien lorsqu'on élève ou abaisse la température ou le degré d'humidité, ou bien lorsqu'on soumet la plante à un environnement bruyant ou à un champ magnétique ou électrique, ou bien lorsque Referring to Figure 1, a pair of electrodes 2 is inserted into or fixed to the rib 1a of a leaf 1 of a plant and there is an amplifier 3 and an output system 4. As shown in Figure 1, when a pair of electrodes 2, 2 is inserted into or fixed to the rib 1a of the leaf 1 of a plant, with a predefined interval, a voltage, corresponding to the rib current which passes inside, is established between the electrodes 2.2. The rib current varies according to the state of the plant at the instant considered. For example, when irradiating ultraviolet or infrared light on the plant, or when raising or lowering the temperature or humidity, or when subjecting the plant to a noisy environment or a magnetic or electric field, or when
1 'on met la plante sous une atmosphère NO2, le courant de 25 nervure varie. 1 put the plant in a NO2 atmosphere, the rib current varies.
En conséquence, si l'on a fait varier au préalables les conditions exerçant une influence sur la culture de la plante qui reçoit les radiations de lumière ultraviolette ou infrarouge et que l'on ait alors détecté et mesuré la réaction de la plante, c'est-à-dire la variation du courant de nervure à ce moment, d'une manière telle que celle mentionnée ci-dessus, on pourra détecter ultérieurement, à peu près en temps réel, les variations-de l'environnement fourni à la Consequently, if the conditions having an influence on the culture of the plant which receives the radiations of ultraviolet or infrared light have been varied beforehand and the reaction of the plant has then been detected and measured, that is to say the variation of the rib current at this moment, in a manner such as that mentioned above, it will be possible to detect later, approximately in real time, the variations in the environment supplied to the
plante, en fonction de la variation du courant de nervure. plant, depending on the variation of the rib current.
En outre, divers types de dispositifs peuvent être considérés, en ce qui concerne le système de sortie destiné In addition, various types of devices can be considered, with regard to the outlet system intended
à rendre perceptible ladite tension entre les électrodes. to make perceptible said voltage between the electrodes.
Par exemple, on peut considérer, en tant que système de sortie pour imprimer ou rendre perceptible le signal détecté, un dispositif d'enregistrement qui imprimera le signal de tension détecté sur un support d'enregistrement tel que du papier d'enregistrement ou similaire, un dispositif à mémoire qui emmagasinera ledit signal dans un support de mémoire tel qu'une bande magnétique ou similaire (dispositif dans lequel, 10 si le signal détecté est converti de la forme analogique à la forme digitale et emmagasiné dans le dispositif à mémoire, on peut facilement exécuter un traitement par ordinateur), un dispositif de visualisation, comme un tube à rayonS cathodiques,un dispositif sonore o un hautparleur est alimenté 15 par le signal de tension obtenu par modulation de fréquence For example, one may consider, as an output system for printing or making perceptible the detected signal, a recording device which will print the detected voltage signal on a recording medium such as recording paper or the like, a memory device which will store said signal in a storage medium such as a magnetic tape or the like (device in which, if the detected signal is converted from analog to digital form and stored in the memory device, can easily carry out processing by computer), a display device, such as a cathode ray tube, a sound device where a loudspeaker is powered by the voltage signal obtained by frequency modulation
du signal de tension détecté mentionné ci-dessus, etc... of the detected voltage signal mentioned above, etc.
En pratique, la Demanderesse a réalisé une expérience dans laquelle une paire d'électrodes, comme mentionné ci-dessus, est insérée dans la veine d'un saintpaulia (violette africaine), le signal de tension de sortie engendré In practice, the Applicant has carried out an experiment in which a pair of electrodes, as mentioned above, is inserted into the vein of a saintpaulia (African violet), the output voltage signal generated
entre les électrodes est amplifié et modulé et ce signal est émis par le haut-parleur, qui fait ressortir les zones sonores de basse fréquence et de haute fréquence. between the electrodes is amplified and modulated and this signal is emitted by the loudspeaker, which brings out the low frequency and high frequency sound zones.
Il en résulte que, lorsque l'on irradie de la 25 lumière ultraviolette ou infrarouge sur la plante, ou lorsque la température ambiante ou le degré d'humidité sont élevés ou abaissés, le haut-parleur émet la plainte de la plante qui souffre.. Au contraire, -lorsque l'environnement de la plante devient proche de celui de l'état naturel ordinaire, 30 le haut-parleur émet un son qui lui est propre. Enfin, lorsque l'on irradie la plante avec des rayons lumineux ne contenant ni ultraviolet ni infrarouge, -le haut-parleur peut émettre le son exprimant la joie de la plante. En conséquence, on As a result, when ultraviolet or infrared light is irradiated on the plant, or when the ambient temperature or the humidity is raised or lowered, the loudspeaker emits the complaint of the suffering plant. On the contrary, when the environment of the plant becomes close to that of the ordinary natural state, the loudspeaker emits its own sound. Finally, when the plant is irradiated with light rays containing neither ultraviolet nor infrared, the loudspeaker can emit the sound expressing the joy of the plant. Consequently, we
peut facilement juger, en écoutant le son émis par le haut35 parleur, si l'environnement effectif de la plante est préfé- can easily judge, by listening to the sound emitted by the loudspeaker, whether the actual environment of the plant is preferred.

Comme il apparaît à la lecture de la description précédente, selon la présente invention, il peut être As it appears on reading the preceding description, according to the present invention, it can be
possible de trouver l'environnement préférable pour la plante, à peu près en temps réel. La plante peut être cultivée dans l'environnement préférable pour la plante. En outre, la plante n'est pas cultivée seulement selon les désirs humains, mais elle est cultivée dans l'environnement préférable pour la plante aussi. 10 possible to find the preferable environment for the plant, roughly in real time. The plant can be grown in the environment preferable for the plant. In addition, the plant is not grown only according to human desires, but it is grown in the preferable environment for the plant too. 10
