DEVICE FOR ACCESSING AN UNDERGROUND OR OVERGROUND CIVIL ENGINEERING INFRASTRUCTURE HAVING A MULTI-PROTOCOL COMMUNICATION MODULE, AND SYSTEM FOR MANAGING A FLEET OF ACCESS DEVICES

摘要

The invention relates to a device for accessing an underground or overground civil engineering infrastructure, having a hatch (1) for accessing a room. The hatch has a communication module (3) having at least one antenna for transmitting a signal on at least one wireless communication network. The communication module (3) is a multi-protocol communication module, so as to be able to transmit a signal in accordance with at least two wireless communication protocols or in accordance with at least one wired communication protocol and at least one wireless communication protocol. This guarantees continuity in the transmission of data from or to the communication module. The invention also relates to a system for managing a fleet of such access devices.
