DEVICE FOR ACCESSING AN UNDERGROUND OR SURFACE INFRASTRUCTURE COMPRISING A MULTI-PROTOCOL COMMUNICATION MODULE, AND SYSTEM FOR MANAGING A PARK OF ACCESS DEVICES

摘要

The invention relates to a device for accessing an underground or surface infrastructure, comprising a hatch (1) for accessing a room. The hatch comprises a communication module (3) comprising at least one antenna allowing the emission of a signal on at least one wireless communication network. The communication module (3) is of the multi-protocol type so as to be able to transmit a signal according to at least two wireless communication protocols or according to 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.
