Method and system for providing explosion proof video and communication relay module

摘要

Embodiments of methods, devices and systems are presented for communicating information in an explosive environment. An explosion proof video and data communication module includes features that prevent the generation of a spark or other ignition sources that could ignite explosive dust, gas or vapors in the air. The explosion proof video and communications relay modules may operate independently or as a group to provide real-time information, situation awareness, functionally and responsiveness for personnel that are in explosive environments.

主权项

1. An explosion-proof communication device, comprising:
a non-conductive housing; a first antenna; a second antenna; a radio receiver; a radio transmitter; a battery coupled to a fault tolerant circuit element; and a processor coupled to the first antenna, second antenna, radio receiver, radio transmitter, and battery, wherein the processor is configured with processor executable software instructions to perform operations comprising:
receiving radio frequency signals from the first antenna at a first frequency via the radio receiver; andretransmitting the received frequency signals from the second antenna at a second frequency via the radio transmitter, wherein the first frequency is different from the second frequency, and wherein the processor, first antenna, second antenna, radio receiver, radio transmitter, battery, and fault tolerant circuit element are hermetically sealed inside the non-conductive housing.
