METHOD AND SYSTEM FOR CALCULATING AND REPORTING SLUMP IN DELIVERY VEHICLES

摘要

The present invention relates to a system for the delivery of concrete, a wireless rotational sensor and a device for determining the rotation of a concrete mixing drum on a concrete delivery truck. The wireless rotational sensor for detecting the rotation of a mixing drum on a concrete delivery vehicle includes an accelerometer mounted to the mixing drum. A wireless transmitter coupled to the accelerometer transmits a signal reflective of rotation of the mixing drum. A wireless receiver receives the signal reflective of drum rotation. A computer processor can also be included, coupled to the accelerometer and wireless transmitter and configured to determine angular motion of the concrete mixing drum from the accelerometer signal. Conversely, the computer can be coupled to the wireless receiver and configured to receive the signal reflective of rotational state from the wireless transmitter and determine angular motion of the concrete mixing drum therefrom.
