System and method for wireless updates for industrial cellular communication devices in hazardous locations
First Claim
1. A system for updating an industrial cellular communications device, said system comprising:
- a super capacitor and a cellular modem that is connected electronically to said super capacitor, wherein said cellular modem receives input from said super capacitor;
an external serial Flash component that receives input from said super capacitor;
a host that communicates bidirectionally and wirelessly with said cellular modem over a packet based wireless communications; and
a microcontroller that is connected electronically with said cellular modem and which communicates bidirectionally with said cellular modem and receives input from said super capacitor and wherein said microcontroller further communicates bidirectionally with said external serial Flash component, wherein said microcontroller facilitates monitoring with said cellular modem of a voltage associated with said super capacitor and a temperature associated with said cellular modem, wherein said host establishes a data call with said cellular modem, said data call composed of a data transfer between said host and said cellular modem, and wherein when said voltage associated with said super capacitor attains a lower voltage limit, said cellular modem stops receiving data and sends a status code to said host and disconnects said data call and data transfer and enters into a sleep mode during which time said super capacitor is recharged and wherein said cellular modem reestablishes said data call with said host after said super capacitor has been recharged.

Abstract
A system and method for updating industrial cellular communications devices. A supercapacitor and a cellular modem are connected electronically to one another. A host can communicate bidirectionally and wirelessly with the cellular modem. A microcontroller is connected electronically with the cellular modem, such that the microcontroller facilitates monitoring with the cellular modem of a voltage and temperature associated with the super capacitor. When the voltage of the super capacitor attains a lower voltage limit, the cellular modem stops receiving data from the host and sends a status code to the host and disconnects a data call and data transfer and enters into a sleep mode during which time the super capacitor is recharged. The cellular modem can reestablish the data call with the host after the super capacitor has been recharged.
