Description

The proposed technical solution relates to information-measuring equipment and can be used in systems for recording, storing and transmitting data in unmanned aerial vehicles (UAVs).

The prior art method for recording telemetric information of a spacecraft (KA) (RU, patent No. 2498399, IPC G06F 17/00, Н04В 7/185), in which telemetry information from each block of recording equipment, including functional groups of sensors located on the external side of the spacecraft, enters the on-board measurement system, there it is transformed, processed and transmitted to the ground-based telemetry station.

Telemetry information is also stored in its own memory for subsequent synchronous transmission of digital arrays in the operational reset mode to a ground-based telemetry station when the spacecraft enters dense atmospheric layers.

This method is carried out by a spacecraft system, including several blocks of recording equipment, a control and data processing unit, a pairing device, an autonomous timer device, a single-board computer, a system of temperature sensors, a storage device, a synchronous data transmission unit, and a secondary power supply unit.

The disadvantages of this method and system are the complexity and high overall dimensions of the system.

The prior art method of recording telemetric information for medium and heavy classes of rocket carriers (http://www.rusnauka.com/5_SVMN_2013/Tecnic/6_129395.doc.htm), in which signals are recorded, converted, processed and transmitted to a ground-based telemetry station .

This method is implemented using the Astra universal small-sized telemetry system, which consists of three units: a telemetric frame former, a switch, and a transmitter. Analog, piezoelectric and temperature sensors, as well as digital subscribers can be connected to the Astra system through four inputs of the RS485 interface.

The disadvantage of this analogue is the difficulty of processing telemetric information and the inability to store it on board an aircraft without transmission to a ground-based telemetry station.

The on-board telemetry system “Orbit-4MT” is known from the prior art (Nazarov A.V. et al., “Modern Telemetry in Theory and Practice”, Publishing House “Science and Technology”, St. Petersburg, 2007, pp. 470-471 ), consisting of a central driver, a bus controller, modules for forming measurement channels, a secondary power source and a meter range radio transmitter. Orbita-4MT operates in the frame of the receiving ground station of the RTS Orbita-TM.

“Orbit-4MT” is a set of functionally complete modules providing a monoblock and device-based layout. Modules for forming measuring channels process signals from the following types of sensors: analog, accelerometers, thermocouples and thermistors, signal and contact.

The disadvantage of the analogue is the insufficient amount of memory of the static storage device and the inability to use telemetric information without transmission to the ground telemetry station, as well as the inability to connect the required number of sensors to the system.

The objective of the invention is to eliminate the above disadvantages and create a method for recording telemetric information of an unmanned aerial vehicle and a device for its implementation, which allows to collect telemetric information from the required number of sensors, increase the volume and reliability of the received telemetric information, accelerate its processing and reduce the weight of UAVs.
