Abstract

A sensing system for road construction equipment that includes a mounting bracket secured to a road construction vehicle that has an RFID tag. A wireless sensor is provided with an RFID reader so that when the wireless sensor is secured in the mounting bracket the RFID scanner is adjacent the RFID tag and scans and reads the RFID tag sending location information of the wireless sensor to a master controller.

Claims

1. A sensing system for road construction equipment comprising:

a road construction vehicle;

a mounting bracket having a machine readable medium affixed thereon;

a wireless sensor mounted on the mounting bracket and having a reading device; and

wherein when the wireless sensor is mounted on the mounting bracket the reading device scans the machine readable medium.

2. The sensing system of claim 1 further comprising a plurality of sensors remotely located from and in communication with the wireless sensor.

3. The sensing system of claim 1 further comprising a master controller associated with the road construction vehicle that is electronically connected to the wireless sensor to receive data obtained from the scanning of the machine readable medium.

4. The sensing system of claim 3 wherein the data pertains to the location of the wireless sensor.

5. The sensing system of claim 1 wherein the machine readable medium is a radio frequency identification tag fixed on the bracket.

6. The sensing system of claim 5 wherein the reading device is a radio frequency identification reader.
