The method enables the automatic detection of stability limit operation of a bulk product pneumatic conveyor installation operating in dense phase, in which the conveyor gas and the bulk product are separately introduced into a lock (3) which communicates at its outlet with a duct (4) for bulk product pneumatic transport. It consists in measuring the pressure (Pe), called lock pressure, which is exerted by the conveyor gas in the proximity of the zone (3a) where the bulk product is introduced into the conveying duct (4), and in detecting an instability of the measured lock pressure (Pe), over a predetermined duration (t), by means of a preset stability criterion. Specifically, the stability criterion consists of producing at least one fuzzy cut-off of the measured pressure (Pe) values, based on a predefined membership function, sampling period, and interval, and computing a stability coefficient based on this fuzzy cut-off.

Le procédé permet de détecter automatiquement un fonctionnement en limite de stabilité d'une installation de transport pneumatique d'un produit en vrac en phase dense, dans laquelle le gaz de transport et le produit en vrac sont introduits séparément dans une écluse (3) qui communique en sortie avec une conduite (4) pour le transport pneumatique du produit en vrac. Il consiste à mesurer la pression (Pe), dite pression d'écluse, qui est exercée par le gaz de transport au voisinage de la zone d'introduction (3<u>a</u>) du produit en vrac dans la conduite de transport (4), et à détecter une instabilité de la pression d'écluse (Pe) mesurée, sur une durée prédéterminée (t), au moyen d'un critère de stabilité prédéfini. Plus particulièrement, le critère de stabilité consiste à réaliser au moins un découpage flou des valeurs de pression (Pe) mesurées, selon une fonction d'appartenance, une période d'échantillonnage, et sur un intervalle prédéfini, et à calculer un indice de stabilité à partir de ce découpage flou.
