A security system having a control unit in communication with detection devices and notification systems to provide messages. Methods for employing a control unit are also provided herein.

Communication module for a security system and method for same

Disclosed are method and system for treating concrete in mixing drums of delivery vehicles having automated rheology (e.g., slump) monitoring systems programmed to dose fluids into concrete based on the monitored rheology. The present invention takes into account a Revolution-To-Discharge value ('RTD') which reflects drum rotations needed to move concrete towards and through the mixing drum opening from which concrete is discharged, and also takes into consideration a Volume-Per-Revolution-Upon-Discharge ('VPRUD') value which reflects the relation between the rate of discharge and rheology (e.g., slump) of concrete upon discharge. The invention is especially useful for reclaiming concrete in the drum after delivery and can confirm rheology based upon peak (maximum) discharge pressure. The present inventors found surprisingly that discharge pressure readings are useful for recalibrating automated rheology monitoring systems as well as for reporting and/or treating the remainder concrete.

The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response ('NDR') curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.

Treating and reporting volume of concrete in delivery vehicle mixing drum

A system for managing a concrete delivery vehicle having a mixing drumand hydraulic drivefor rotating the mixing drum, including a rotational sensorconfigured to sense a rotational speed of the mixing drum, a hydraulic sensorcoupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, a temperature sensor for sensing temperature of the drum, and a communications portconfigured to communicate a slump calculation to a status systemcommonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum. Temperature readings are further used to qualify or evaluate a load. Also, water purge connections facilitate cold weather operation.
