GPS tracking based tire pressure monitoring system


TPMS, as a wireless technology used on vehicles, is a good assistance for tires when fleets or logistics companies are trying to improve the productivity and optimize the tires maintenance in better tires management. But if a TPMS kit just only inlcudes a display screen installed on dashboard for driver, which highly affected the tires management and more limitations on the use of TPMS. it's definitely yes that driver may be notified by the screen with its sound or different colors on screen:
driver! driver! I am noticing one of tires is too hot or too high/low in pressure! attention, attention please!

Some drivers are not that sensitive during driving. Like they are focusing on road environment through the dashboard or the rearview mirror. They are more caring about vehicles passing by, obstacles suddenly occurring on front of road. But indeed, they can most possibly receive the instant notice from TPMS.

But, there are drawbacks that they can only offer you the instant notice of abnormal tires pressure or temperature, which can let driver handle such problems immediately. How about the long time tire pressure or temperature changes history? How about the difference of each tires in performance during a trip? How about the monitoring of a tire during summer or winter? How about the tire status when driver is off duty? How about the tires theft alarm when driver is not in cab? With these issues, we need to mointior ties remotely and saving these TPMS data continuoulsy whenever driver is there or not: GPS tracking based TPMS.

GPS tracking based TPMS is a better solution in tire management.

Besides the benefits of wireless standalone TPMS, GPS tracking based TPMS offers more. If users installed GPS tracking based TPMS on vehicles, the system would continuously receive TPMS signals from TPMS sensors which installed on tires via radio frequency RF433.92MHz, and forward these TPMS data to server via 2g/3g/4g. Users can observe changes of pressure and temperature of one tire during trip, can compare pressure and temperature between one tire and the other to understand the two tires performance during the trip. Users can know the tire's quality, and how they weaken in long term. You also will know the pressure and temperature of each tire is different. Even it's different in pressure and temperature if the tires in sunny position or dark side. These specific and systematic data can support enterprises tires management:

whether we should check if any leaking spots on tires;
● whether we need to change tire valves;
● whether we need to inflate tires or decrease the tire pressure by leaking some air;
● whether we need to change tires;
● whether we can use some tires additives to obtain better tire performance;
● whether we need to balance two tires pressure to have same friction and wheel adhesion.

Each statistics can guide you to take some actions for tires management. All these can lead to lower maintenance cost, better driving experience, higher productivity, prolong tires life.

Tire RFID function

Another use for GPS tracking based TPMS is tire RFID function. Every TPMS sensor has its unique 8bytes hex ID saved in chip ROM. We can use this unique sensor ID in RFID management. Each TPMS sensor can map to tire position with sensor ID. clients can have tire profiles with TPMS sensor ID,installed time, use time, tire pressure and temperature data history. Comparing to current tire RFID tags used in tire management, TPMS RFID has big edges. Current tire RFID tag is developed on UHF 902-926MHz, which has 1meter to 3meters wireless distance. It means the user can only put the UHF reader closer to tires to read RFID tag ID, it would be much work and inconvenience. If there are more than 10 tires, it would cause much time consumption. and what's more, the UHF reader is big in size. Not easy to take the big UHF reader from tire to tire.

TPMS as RFID has no such issues.
● You can monitor these tires remotely via 4G/WIFI.
● you don't need to put the reader close to tires one by one. You can continuously monitor tire via RFID. the TPMS receiver can receive tire RFID from 30 or 40 meters away.

Tires anti-theft function

When drivers are off duty and walk away, gps tracking based TPMS can offer you the tire theft alert. If one TPMS sensor installed on one tire is not received by TPMS receiver over 2minutes, and system detects the continuous trembles, it would judge tire anti-theft happens.

Overall, gps tracking based TPMS can offer better and more functions: more comprehensive tire status analysis, tire RFID, tire anti-theft, etc. TPMS whether it's standalone TPMS or gps tracking based TPMS, is an advanced and more convenient technology to assist us to understand tires better, know the world better. We won't handle the tires issue without any data. You will have better control on your vehicles or your fleet!
