Methodology to extend battery power in asset-tracking device
A protocol and methodology that extends the battery power in a remote asset tracking device by storing location data more than once (i.e., “n” times), yet transmitting that data only once to a server. In other words, multiple data points are transmitted simultaneously. Devices and systems incorporating the protocol are also provided.
1. A method of using a data protocol for a wireless device, the data protocol comprising:
determining a first location of the wireless device and saving the determined first location of the device;
determining a second location of the device subsequent to determining the first location and saving the determined second location of the device;
transmitting a data packet comprising the first location and the second location to a server;
mapping, at the server, the second location;
after mapping the second location, mapping, at the server, the first location;
running, at the server, a statistical algorithm on the mapped first location and the mapped second location to determine a precise location; and
reporting, by the server, the precise location.
2. The protocol of claim 1 further comprising:
determining a third location of the device subsequent to the second location and saving the determined third location of the device; and
transmitting the data packet comprising the first location, the second location and the third location to the server;
mapping, at the server, the third location before mapping the second location;
running, at the server, the statistical algorithm on the mapped first location, the mapped second location and the mapped third location to determine the precise location; and
reporting, by the server, the precise location.
3. A method of using a data protocol for a wireless device, the data protocol comprising:
sequentially determining “n” number of locations of a device and saving the “n” number of locations of the device in a data packet, where “n” is an integer two or greater;
transmitting the data packet to a server;
mapping, at the server in a reverse order of determining, the “n” number of locations from the data packet;
reporting, by the server, the “n” mapped locations; and
running, at the server, a statistical algorithm on the “n” mapped locations to determine a precise location.
4. The protocol of claim 3 wherein “n” is three.
5. The protocol of claim 3 wherein “n” is four.
6. The protocol of claim 3 wherein “n” is two.
7. An asset tracking system comprising:
a wireless tracking device comprising a GPS/GLONASS system, an RF communication module or a cellular communication module configured to transmit information to a remote server, non-volatile memory, and a control system comprising a data protocol; and
an asset intelligence (AI) server;
wherein the data protocol is configured to:
determine “n” locations of the device and store those “n” locations in the memory,
where “n” is an integer two or greater, and
transmit the stored “n” locations to the AI server as a batch;
wherein the AI server is configured to:
map, in a reverse order of determining, the “n” number of locations from the data packet, and
run a statistical algorithm on the “n” mapped locations to determine a precise location.
8. The asset tracking system of claim 7 further comprising a display to report the precise location.
9. The asset tracking system of claim 7 further comprising a mobile station assistance (MSA) system.
