Monitoring of battery boxes
The need
In the case of work under a temporary speed limit (LTV), battery boxes are used to provide electrical power to the construction crocodiles, which ensure the repetition of temporary signals to the train driver.
The electrical power supply to the construction crocodile is provided by an 18V battery and by a set of cables, the maintenance of which in operational conditions is essential during the work.
The field teams expressed the need to mechanically reinforce the battery box and to digitize it, in order to optimize its management and to carry out remote diagnostic operations.
The proposed solution
The proposed prototype is composed of a battery box, reinforced and dismantled by the integration of a connected box and its measurement additive, and a human-machine interface.
This allows the geolocation of the battery box, the evaluation of its charge level and the general condition of its cabling.

Pierman, the main French manufacturer of composite equipment for passive or connected rail signalling.
The main activity of the PIERMAN group is the design and manufacture of industrial parts made of composite materials (glass-polyester and carbon-epoxy).
This group of 3 SMEs, employing just under 100 employees, is organized around DESCHAMPS Père et Fils, bought by the family group in 2004, which was originally a nautical manufacturer. The company knew how to use its mastery of composite materials to diversify in the manufacture of automatic level crossing barriers for SNCF, the beginnings of an innovative spirit that will no longer be denied.
Holder of numerous patents, PIERMAN is now the main French manufacturer of passive railway signalling equipment (warning lights, frames-screens, barriers for PN, support plates, etc.). It also designs and manufactures a number of other industrial composite products for many other sectors.
Their latest innovation? The PIERMAN group offers its customers the possibility of digitizing its composite products, while respecting its values of sustainability, industrial price and criteria derived from eco-design.
The Rail Open Lab is an excellent vehicle for showing mastery of these recent topics, on concrete use cases.
