Data Logging GPS Vehicle Tracker without SIM Card
Oner GPS tracker with data logger
Using GPS tracker to improve fleet operation is too easy of a solution, with limitation, of course.
When the car goes to the place with weak GSM network or no network , online tracking is down. It is unable to do tracking in real time, but GPS signal is still there. It is necessary to get the tracking data, which help to know what happen during this time.
Then how to ensure no loses of tracking data ?
The current solution is to store tracking data to the flash in the tracker, and resend it to the tracking system.
1. Data store to flash
The storage of flash is 4MB or 8 Mb, 1 data is 0.1-0.2KB, that mean it can store 40,000-80,000 data at least. It looks like the storage is enough, but no one knows how long the car can leave such area ( I.E.: desert area), the flash may just store data for a few days.
What if extend the flash ? sending device back to tracker manufacturer is the only way.
2. Data transfer.
When GSM network recover, GPS tracker starts sending the stored data to the server. At the same time, normal data transfer is processing too. Then that may cause Transmission Interference, still have chance losing tracking data.
In this case, oner make some improvement to this solution.
1. Store data with huge capacity
Store data to SD/TF card ( storage: 8GB-64GB), no worry about loses of data because of full storage. Easy to use, you can extend storage by yourself.
2. Data transfer with different packet
Set tracking data as different packets and transfer to the server. Of course, packet and normal data transfer at different time, to make sure no interference.
3. Confirm message from server
To ensure data sending to server successfully, a confirm message will be sent to the tracer. or else, tracker resend data again.
