摘要： A method for detecting segregation occurring in fresh concrete mixture being agitated in a drum generally includes: rotating said drum about its rotation axis at a low rotational speed for agitating said fresh concrete mixture during at least a rotation; said fresh concrete mixture segregating, said segregating including gravity pulling denser concrete ingredients downwards in said fresh concrete mixture; measuring a plurality of pressure values indicative of pressure exerted onto a rheological probe mounted inside said drum and moving through said fresh concrete mixture as said drum rotates; providing reference data indicative of a behaviour of said rheological probe in a fresh concrete mixture in said absence of said segregating; and detecting that said segregating has occurred, including comparing at least some of said measured pressure values to said reference data.

摘要： There is described a method for determining cleanliness of a drum of a fresh concrete mixer truck. The method generally has: rotating the drum about the rotation axis with a constant torque; using a rotational speed sensor, measuring a plurality of speed values corresponding to speeds at which the drum rotates at different moments in time during said rotating; and using a controller, receiving the plurality of speed values; accessing calibration data having different reference speed values-related data associated to corresponding reference degrees of cleanliness of the drum; comparing at least some of the speed values to the calibration data; and determining a degree of cleanliness of the drum based on said comparison.

摘要： There is disclosed a computer-implemented method for determining a density value of a fresh concrete sample using an acoustic probe assembly. The acoustic probe assembly has an acoustic path, an acoustic emitter configured to emit an acoustic signal along the acoustic path, and an acoustic receiver configured to receive the acoustic signal after propagation along the acoustic path. The acoustic probe assembly is configured and adapted to generate an electromagnetic signal indicative of a duration of time taken by the acoustic signal to travel from the acoustic emitter to the acoustic receiver across the fresh concrete sample. The method generally has a step of determining the duration of time based on the electromagnetic signal, a step of matching the duration to a density value using reference data, and a step of displaying the density value.

摘要： There is described a method for confirming delivery of bulk material from a bed of a dump truck based on hydraulic pressure. The dump truck has a driving device moving the bed between a rest position and a delivery position. The method generally having: using a hydraulic pressure sensor, measuring a plurality of hydraulic pressure values indicative of pressure of a hydraulic fluid of the driving device as the bed is moved; and using a controller communicatively coupled to the hydraulic pressure sensor: monitoring a slope at which at least some of the plurality of hydraulic pressure values vary over a given period of time; and generating a delivery confirmation indicative that a delivery of the bulk material has occurred based on a comparison between said monitored slope and a delivery slope threshold.

摘要： There is described a method for determining a volume of fresh concrete being discharged from a drum during a discharge, the drum being rotatable and having inwardly protruding blades mounted inside the drum which, when the drum is rotated in an unloading direction, force the fresh concrete towards a discharge outlet of the drum. The method generally has discharging a volume of the fresh concrete from the drum by rotating the drum in the unloading direction for a given number of discharge rotations; obtaining discharge flow rate variation data indicative of a discharge flow rate varying as function of discharge rotations; and determining a discharged volume value indicative of the volume of fresh concrete being discharged from the drum of the mixer truck during said discharge based on the given number of discharge rotations and on the discharge flow rate variation data.

摘要： A method and system for calibrating moisture sensors in a concrete production plant are disclosed. The moisture sensor is in communication with a computer database through a transceiver. The moisture sensor records numerous readings of moisture for aggregate used in concrete production, which are stored in the database. Separately, a manual sample of aggregate taken from the production line is determined to have a moisture content, which is the baseline for calibrating the sensor. This record is also entered into the database. The moisture sensor reading and the manual sample record are compared for multiple iterative readings to determine whether a sensor requires further calibration.
