Benefits of technology
[0004]It is, therefore, one aspect of the disclosed embodiments to provide for improved and safe cellular communications for cellular communications devices utilized in hazardous locations.
[0008]The aforementioned aspects and other objectives and advantages can now be achieved as described herein. A system and method for updating industrial cellular communications devices is described herein. In an example embodiment, a super capacitor 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 associated with the super capacitor and a temperature associated with the cellular modem. 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.
Problems solved by technology
Electronic devices such as industrial cellular communications devices having intrinsically safe circuits and which are deployed in hazardous areas are experiencing limitations on maximum power draw and energy storage capacity because of the need to avoid sparks and thermal ignitions in such hazardous areas.
In addition, cellular communications devices (which are often deployed in hazardous areas) require a high current during active communication, and the cellular device's battery cannot drive the required current under such conditions.
A super capacitor in parallel with the battery can be utilized to source the required current, but a limitation here is that the super capacitor recharge time is typically several hours.
Additionally, the charge capacity of a super capacitor drastically reduces at negative temperatures, which results in limiting short duration cellular calls.
Due to short duration call limitations, data uploads and downloads to target devices utilizing cellular media require several recharge cycles to the super capacitor, which worsens at negative temperature.

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.
