1 is a block diagram of an item of teleaction equipment; and fig.
la figure 1 présente un schéma de principe d'un appareillage terminal de téléaction.

background of the invention 1. field of the invention the invention relates to a power supply switchover device for electrical apparatus that associates a storage battery and another source of electrical power which the storage battery is adapted to temporarily replace or interface, as well as to teleaction terminal equipment fitted with a power supply switchover device of this type.
l'invention concerne un commutateur d'alimentation pour appareillage électrique associant un accumulateur à une autre source d'énergie électrique que cet accumulateur est apte à temporairement remplacer ou interfacer, ainsi que les appareillages terminaux de téléaction dotés d'un tel commutateur.

according to a characteristic of the invention, the teleaction equipment includes, firstly, power supply switchover means comprising first and second switching means arranged in series for putting the storage battery into and out of service, by connecting or not connecting it to at least one supply terminal of the apparatus to which the other source of power is also connected, control means responsive to the supply voltage present at said supply terminal and adapted to alternatively set the first switching means to a conducting state or to a blocked state dependent upon whether the voltage present at said supply terminal is greater or not greater than a reference voltage that is a function of the minimum voltage acceptable at the terminals of the storage battery for supplying the relevant equipment, the second switching means, being active when said first switching means are in the conducting state, being themselves blocked as long as the voltage present at said supply terminal is greater than the voltage supplied by said storage battery and, secondly, signaling means which, being connected to the transmitting means of the apparatus, are adapted to generate power supply signaling for transmission over the communications network.
l'invention propose donc un commutateur d'alimentation pour appareillage électrique associant, en une alimentation, un accumulateur et une autre source d'énergie électrique que cet accumulateur est apte à temporairement remplacer ou interfacer, dans une réalisation simple et qui ne présente pas les inconvénients évoqués ci-dessus. ce commutateur est défini par la revendication 1. en ce qui concerne un exemple d'application préférée de ce commutateur, référence est faite aux revendications dépendantes.
