Automatic monitoring system in an explosive environment of a direct current source by storage batteries

Abstract From the Canadian patent

An automatic monitoring system of storage batteries housed in battery rooms comprises an acquisition satellite associated with a sensor to measure various physical parameters representative of the operating state of a pilot battery cell notably the, density, temperature and electrolyte level a data concentrator, located outside the corresponding battery room and arranged to communicate by radioelectric waves with the acquisition satellite, and a centralized processing unit connected to the concentrator by a two-way cabled communication network.
