The invention relates to devices for determining the state of preservation of the goods transported, as well as their gabaritos.

There is a method for remote monitoring of cargo on the railway [1], which consists in receiving a television image of the appearance of the rolling stock on the entrance to the Park arrival, the recording of this image and the detection of the deviation of the image of the observed object from the reference sample image obtained earlier at the Park exit of departure and transferred to the Park prior to your arrival the observed object.

The disadvantage of this method is that it is not possible to determine the status of the cargo inside the car or tank, to detect the loss or displacement, which is extremely important for traffic safety.

There is a method of remote control of the dimensions of the goods loaded on the vehicle, in the process of their movement [4], including monitoring compliance with limits gabaritos loading at the entrance of the structure in the inspection area by means of an optoelectronic sensor and the definition of oversize cargo, characterized in that define the boundaries of the combined area loading gauge and gauge rolling stock outline side of the loading gauge, the gauge rolling stock and set optoelectronic sensors on the specified bounds.

This method implements the electronic clearance envelope for remote control of the dimensions of the goods loaded on the vehicle [4], in the process of their movement for the implementation of this method, containing an optoelectronic sensor to determine the start of the composition and the U-shaped bracket mounted on the rail means, which placed five optoelectronic sensors monitoring gabaritos loading and optoelectronic sensor counting cars, the outputs of all of optoelectronic sensors are connected to the input of the display unit and approval, exit to the showing associated with personal electronic computing machine operator, characterized in that it is further provided with four optical sensors control gabaritos loading, which is installed on CL RU 2249523 SS 3259422 UR borders combined zonal loading gauge and gauge rolling stock outline side of the loading gauge, the gauge rolling stock, and an optoelectronic sensor account wheelset, located on the U-shaped design, with an optoelectronic sensor to determine the start of composition is also situated on the U-shaped structure, and the display unit and agreement executed with the ability to work offline.
