A novel system for providing for safe operation of railgear, that is, a set of guide wheels that allow road vehicles to travel on railroad tracks, based on the use of overload indicators installed on the suspension arm of each guide wheel to give operators a quick, visual representation of whether or not a guide wheel is overloaded.

A method for remote monitoring of operating characteristics of a load cell is provided. The method includes receiving from a plurality of sensors, at a main unit, sensed data indicative of a plurality of operating characteristics of a load cell. The method continues by analyzing at a main unit the sensed data for statistical control and sending alerts to a remote computing device when sensed data of an operating characteristic is outside of a preset threshold. A system for carrying out the method is also provided. The system includes a main unit installed near a load cell, a first sub-unit coupled to a scale of the load cell in wired communication with the main unit, and at least one remote computing device in network communication with the main unit.

A material handling system, associated with the delivery of one or more payloads, may include a material handling vehicle configured to haul a payload from a first location to a second location. The material handling vehicle may include a sensor to obtain information associated with a payload, of the one or more payloads, and a vehicle device configured to receive a signal from the sensor to obtain information associated with the payload and to communicate with a server device, via a network, to send the information associated with the payload and to send and/or receive information associated with a material handling project. The material handling vehicle may further include a vehicle identifier to uniquely identify the material handling vehicle.

A charging system includes load meters mounted in a vehicle, the load meters each measuring a load exerted on an axle or a wheel and deciding a measurement result and an onboard unit that acquires the measurement results of the load meters and is capable of communicating weight information on the weight of the vehicle based on the measurement results to a roadside machine.

Agricultural transport vehicle, in particular mixer-wagon, having at least one hold for agricultural bulk goods and at least one weighing device, in particular a load cell and/or a weighing bar, for detecting the weight of load in the hold; having at least one inertial measuring unit for measuring an acceleration and/or orientation of the agricultural transport vehicle, in particular the hold; and having at least one computing unit which is designed to compensate a raw signal of the weighing device with respect to the measured acceleration and/or orientation.

Weighing systems and methods for dynamic loads are provided. A plurality of sensors are configured to provide force information based on a weight of a bin and a weight of a material in the bin. An IMU is coupled to the bin and configured to provide gyroscope information and accelerometer information based on orientation and movement of the bin respectively. A controller is communicatively coupled to the plurality of sensors and to the IMU. The controller is configured to receive the force information from the plurality of sensors and the gyroscope information and the accelerometer information from the IMU. The controller is configured to compensate the force information based on slope of the bin to provide slope-compensated force information, filter the slope-compensated force information using a Kalman filter to provide filtered force information, and estimate the weight of the material in the bin based on the filtered force information.

The present invention provides methods and systems for determining the weight of a vehicle. Exemplary methods include the steps of: determining with one or more on-board sensors, a sensor output voltage; providing the sensor output voltage information to a processing unit to determine the weight of the vehicle; and displaying the weight of the vehicle on a visual display unit

A refrigeration system 1a includes a refrigerated compartment 2 for storing perishable goods; a refrigeration unit 10 operably coupled to the refrigerated compartment 2; a plurality of sensors including an internal temperature sensor 4 configured to determine a temperature of the refrigerated compartment 2, and a weight sensor 5a configured to determine a weight of the goods located within the refrigerated compartment 2; and a controller 20 configured to: receive data from the plurality of sensors; determine a thermal inertia parameter of the goods located within the refrigerated compartment 2 based upon the temperature of the refrigerated compartment 2 and the weight of the goods; and adjust a mode of operation of the refrigeration unit 10 in accordance with the thermal inertia parameter of the goods.

The application discloses a method, system and related device of implementing vehicle automatically weighing, so as to achieve the automatically weighing of the unmanned vehicle. The method includes: controlling, by a vehicle controller, a vehicle to drive automatically and stop at a weighing position; weighing, by a weighbridge sensor, the vehicle when sensing the vehicle stopping at the weighing position, and sending weighing end information to the vehicle controller; and controlling, by the vehicle controller, the vehicle to start and leave the weighing position when receiving the weighing end information.
