KTS is designed to control metrological and technical characteristics, in particular, to monitor the performance, calibration, calibration of weighing devices, including those related to truck scales, control points (systems) for determining the weight parameters (axle loads, masses) of vehicles in areas roads, both in static and in dynamic weighing modes.

The vehicle for controlling weighing devices (CTS), which is a trailer (Fig. 1, 2, 3), includes a chassis, a body containing a platform 5, sides, a drawbar with a hitch 8, the chassis and the body are connected using a frame, this chassis contains axles with strain gauge sensors 3 (Fig. 4) mounted on each axis, and is configured to change the number of working axes, means for fixing loads are mounted on the body parts, contains a data transmission unit (BPD) 4 mounted on the body parts, in particular on board or on the platform or on the frame.

Strain gauges 3, mounted on each axis of the CCC, allow to measure the created axial loads in areas experiencing the greatest deformation of the working axes. For accuracy of measurements and reliability of their work in various conditions, strain gauge sensors are built into the axis, for this purpose there are recesses on the axis for fixing.

BPD 4 includes a synchronization unit using navigation systems in the form of a GLONASS / GPS sensor receiver, which allows determining the date and time of travel, geographic coordinates of the vehicle, speed of movement, and linking the values of weight parameters (axial loads, group loads, masses) of the vehicle, measured from using strain gauges, to the date, time and place of measurements (tests).

 BAP 4 may include an information storage device, devices for transmitting data via wireless communication (using Bluetooth and / or Wi-Fi, and / or GPRS, etc.) and / or devices, connectors for connecting peripheral devices, connectors for transmitting data via wired communication, in particular USB connectors, necessary for transferring information directly to a server / software and hardware complex or to peripheral devices (smartphone, tablet, flash drive, etc.). Thus, the multifunctionality of the BPD allows you to increase the capabilities of the CCC and use it by choosing the types of information transfer convenient or depending on what means of receiving information are available under given test conditions.

The chassis contains at least one non-lifting axle 1, at least one lifting axle 2, which allows you to change the number of working axles. The execution of the axles can be varied and combine different combinations: the extreme axles of the chassis are made non-lifting 1; at least one lifting axle 2 is located between the non-lifting axles 1 and / or at least one non-lifting axle 1 is located between the lifting axles 2; lifting axles 2 are located between non-lifting axles 1.

Preferred versions of the chassis of the vehicle for controlling weighing devices:

the chassis is made triaxial and contains one lifting 2 and two non-lifting wheel axles 1, while the lifting axle 2 is located between the non-lifting axles 1 located at the edges;

the chassis is made four-axis and contains two lifting 2 and two non-lifting 1 axles, while the lifting axles 2 are located between the non-lifting axles 1 located at the edges.

The undercarriage contains at least one device for lifting the axis 2, which allows you to adjust the number of working axles. Moreover, the device allows you to lift the axis with its separation from the supporting surface. The ability to change the number of working axles allows you to create types of vehicles with various combinations of axle positions on the basis of one KTS.

To reproduce the reference values of the weight parameters for the given conditions, in particular when weighing in motion, allow means for fixing loads.

Means for securing goods, fixed on the body parts, in particular on the platform and / or sides, and / or the frame, can be made in the form of fastening elements 6 for linking, stretching, strapping, ties, which can be used loops (staples and / or rings) for securing goods with chains, belts, ribbons, cables, nets or coatings with fastening means depending on the type of cargo. These elements are suitable for securing many types of cargo, which in turn also affects the versatility of the control vehicle for different test conditions. In this case, the fastening elements in the form of loops also means the use of brackets, rings, eye bolts and other fastening elements of this kind, as well as their joint use. At the same time, the use of various types of fastening allows you to create reliable cargo securing for more accurate tests in the weighing mode in motion, since the means of securing the cargo can prevent sliding, tipping, rolling and moving the goods and their components placed in the body in any direction.

Also, the means for securing cargo can be made in the form of guides formed by protrusions 7 having the shape of a truncated cone for placing weights with reciprocal cavities under the protrusions mounted on the body platform. They allow you to ensure a stable position of the goods in the form of weights during the movement of the control vehicle, which is essential when conducting tests (measurements, checks, verifications, calibrations). The shape of the weights makes it possible to put them on top of each other, thereby creating a high specific nominal load per square meter of body platform area and allowing reproducing the required loads for certain test conditions. On the body platform there is a flooring made of damping material with holes for protrusions having the shape of a truncated cone or without holes for protrusions if they are absent, which reduces the effect on the measurement error in movement, creating additional stability to the position of weights / weights during the movement of the control vehicle . The ability to use weights in the form of reference weights also allows you to control the KTS itself and make more accurate measurements when controlling weight devices.

Thus, means for securing goods allow you to reproduce the reference values of the weight parameters for the given conditions

Trailer power supply (CTS) can be carried out either from the onboard network of the tractor through a separate power connector on the trailer, or from an autonomous power source. Using a vehicle in the form of a trailer allows you to create a more accurate vehicle for controlling weighing devices, regardless of the characteristics of the tractor (mechanical vehicle). This is due to the fact that the weight of the load is transferred to the road through the trailer frame and distributed on the trailer axle, without transferring the load on the tractor axle.

Thus, the claimed vehicle for controlling weighing devices allows you to create axial loads by changing the number of working axles and placing loads with different weights, measure the generated axial loads, both in static and dynamic weighing modes using strain gauge sensors, transmit data using data transfer unit.

The principle of operation of the vehicle for controlling weighing devices is given for a trailer, which is a multi-axle vehicle with the number of axles equal to three or four, the extreme axles are non-lifting, and the axles located between them are lifting due to the devices for lifting the axles and are in the raised position. Each axis has built-in strain gauge sensors located on both sides of the axis experiencing the greatest (maximum) strains on both sides. The strain gauge sensors are connected to the synchronous measurement unit (hereinafter - LSI), which transmits the received data to the data transfer unit. BPD includes a synchronization unit using navigation systems (GLONASS / GPS sensor receiver). BPD transmits data to a server / software and hardware complex, data is transmitted via wireless (Wi-Fi).

The server processes and analyzes (compares) the data received from the CTC and from the weighing device that is part of the automatic complex (system) that determines the weight parameters while moving the CTC through the control zone of the complex with the weighing device. The vehicle for controlling weighing devices allows you to transfer the following data to the server: date and time of travel, geographical coordinates, speed, total weight, axle loads and axle groups of the control vehicle. The server compares the received data. As a result, it is possible to identify malfunctions, deviations or confirm the operability of the weighing device.

The determination of weight parameters is based on the reproduction of axial loads under the action of gravity and their measurement in static mode or in dynamic (while moving) weighing mode, both on the weighing device and on the CCC itself.

A loaded CTS, in accordance with the weight parameters established on a given section of the road, within its load capacity, when tested in the static weighing mode, must stop each axis on the load receiving platform of the weighing device to ensure load calculation on individual axes; during tests in the dynamic mode of weighing, it must pass along the load-receiving platform of the weighing device to ensure the calculation of the load during movement. In order to compare the obtained values of the weight parameters of the weighing device with the data measured by the control vehicle, both systems must be synchronized. This is possible through the use of navigation systems using the exact time of the GLONASS / GPS signal as a time standard for both systems.

Presented as an example, a high-precision universal CTS can be used in combination with a tractor (power-driven vehicle) of any kind, due to the fact that additional special tools are not required for the operation of the CTS.

In these application materials, a preferred disclosure of the implementation of the claimed technical solution was presented, which should not be used as limiting other, private embodiments of its implementation, which do not go beyond the scope of the requested legal protection.

All elements of the claimed technical solution are firmly interconnected and represent a single device aimed at performing a single function.

All the features of the utility model in aggregate are in a causal relationship with the claimed technical result, they allow you to create a highly accurate universal control vehicle for monitoring under different conditions of testing weighing devices, customizable for specific weight parameters (to reproduce reference values of weight parameters for given conditions) corresponding to metrological requirements for specified test conditions (performance monitoring, verification, to and calibration of al.), both in static and in dynamic (moving) weighing modes.
