Description

The invention relates to radio telemetry devices and can be used as part of a transport tank container or tank container for remote monitoring of the condition of transported dangerous cargo, mainly liquefied hydrocarbon gases, liquefied ammonia, freons, carbon dioxide, cryogenic products, etc.

The closest analogue of the claimed invention is an autonomous portable device for remote monitoring of cars (utility model patent RU No. 201638), containing a housing with at least one solar battery on its surface, built-in antennas, a main battery, a backup battery, a position determination module using satellite systems, a module for transmitting data to a server for collecting information and determining the LBS position, a control microcontroller, an adapter for transmitting voltage from solar panels to the main battery, a module for attaching the body to the car.

At the same time, the main disadvantages of the known technical solutions are both their highly specialized purpose and the inability to use them to monitor the condition of dangerous goods transported in a liquefied state in a transport tank container or tank container. The lack of timely information about changes in the technical condition of the vessel during operation of the tank container can lead to a change in the current parameters of the dangerous cargo (temperature, pressure, liquid level in the vessel). This may result in product leakage through the safety valves and lead to an explosion hazard.

The technical objective of the claimed invention is to automate the processes of receiving, processing, storing and transmitting data to the dispatch center during remote monitoring of the condition of transported dangerous goods.

The solution to the technical problem is achieved by the fact that the device for autonomous telemetric monitoring of the condition of a transport container consists of a housing made in the form of a rectangular parallelepiped with rounded corners and a built-in unit for fastening to a tank container, and the housing is made in a fire- and explosion-proof dust-proof design and is equipped with a radio frequency identification tag, built into the housing and connected via the system bus: control and display unit; a charge controller to which a solar battery located in the upper part of the housing is connected; a power supply to which a battery pack connected to a charge controller is connected; data reception and transmission module; GPS/GLONASS receiver; connector block for connecting temperature sensors; pressure transducer; differential pressure converter; a data storage unit and a microprocessor configured to process information received from the GPS/GLONASS receiver, a block of connectors for connecting temperature sensors, a pressure transducer and a differential pressure transducer.

To simplify the replacement of the pressure transducer and the possibility of using an external pressure transducer, a connector for connecting an external pressure transducer can be installed instead of the pressure transducer.

To simplify the replacement of the differential pressure transmitter and the ability to use an external differential pressure transmitter instead of the differential pressure transmitter, a connector for connecting an external pressure transmitter can be installed.

The technical result achieved by the stated set of features is to increase the safety of operation of tank containers by implementing the possibility of predictive information about changes in the technical condition of a tank container during operation. This allows, in particular, to prevent leaks and prevent the formation of explosive and/or toxic mixtures in the air.
