Description

This utility model relates to meteorology, in particular to radio sounding.

Closest to the claimed technical solution is a universal small-sized radio probe (UMR), which includes a transceiver, a microcontroller, analog and digital sensors, an antenna, which additionally has an interface, a highly stable frequency synthesizer, a GLONASS receiver and a GPS receiver, the antenna is structurally made on a printed circuit board in a microstrip antenna in common with the transceiver and a frequency synthesizer are installed in the transceiver, while GLONAS and GPS receivers, analog and digital sensors, int rfeys and a transceiver connected to the microcontroller [1].

The disadvantages of UMR is that it:

- has a microstrip antenna on a printed circuit board, which does not allow the formation of the radiation pattern necessary for conducting radio sounding at large distances (up to 250 km) from the receiving ground station;

- uses a frequency synthesizer to set the transmitter frequency, which leads to an increase in the cost of the radiosonde.

- does not allow connecting more than five digital sensors for measuring atmospheric parameters;

- does not have an external bus for connecting additional digital sensors;

- does not include the ability to create an interference-free digital code for transmitting information to a ground receiving station to eliminate errors in data transmission;

- is capable of receiving signals from only two satellite navigation systems - the Russian GLONASS and the American GPS, and is not able to work with the European GALILEO system;

The tasks to be solved by the claimed utility model are:

- the use of a transmitter that does not use a frequency synthesizer and super-regenerative mode.

- the ability to connect additional digital sensors of meteorological variables;

- providing a signal reception range of at least 250 km from the receiving ground station;

- compatibility with three GLONASS / GPS / GALILEO satellite navigation systems;

- elimination of errors when transmitting data to a ground receiving station.

These tasks are solved due to the fact that the GLONASS / GPS / GALILEO combined receiver, a modulator for creating an noise-free digital code for transmitting the measured parameters to the receiving station, and a pin transmitting antenna are additionally introduced into a specialized aerological digital radio probe containing a microcontroller and a transceiver; external digital bus with a subsystem for interrogating digital sensors and connected transceivers, with the ability to connect arbitrary sensors, the number of connected sensors being unlimited within 64, the configuration of connected sensors is determined automatically after turning on the radiosonde. The components of the radiosonde are selected and the housing is designed to operate in low temperature and pressure conditions. The digital transmission of the measured parameters to the receiving station is organized with the aim of minimizing the alteration of the hardware of the ground-based radio sounding systems operating on the aerological network of Roshydromet. When working with a radiosonde, frequency shift keying is used for data transmission.

The essence of the utility model is illustrated in figure 1.

The device operates as follows:

The basis of the radiosonde is a microcontroller, which acts as a digital signal shaper for transmission to the ground receiving system. All the sensors of a specialized radiosonde are connected to the main microcontroller via a serial bus. Each sensor is a measuring element (for the corresponding measured parameter) connected to the ADC and having a processing microcontroller or special processor. The microcontroller converts the measured parameters into a digital code and transfers it via the serial bus to the main microcontroller, which has an output to the microwave module to transmit information to the ground receiving system. Data transmission to the ground receiving station is carried out in a digital, noise-protected code using frequency manipulation. The GLONASS / GPS / GALILEO module allows you to determine the coordinates of the radiosonde through GLONACC, GPS and GALILEO systems.

Thus, the proposed design allows you to expand the functionality and increase the efficiency of the radiosonde due to the possibility of introducing a digital bus for connecting additional sensors, transmitting noise-protected digital information to the ground station, increasing the range of the radiosonde reception by the ground station.

It is supposed to introduce a utility model on the aerological network of the Russian Federation.
