DEVICE FOR MEASURING meteorological parameters and signal TELEMETRY upper-air radiosonde

摘要

The invention relates to measuring equipment and can be used in the devices measuring the temperature and humidity, including meteorological radiosondes for measurement of vertical profiles of meteorological parameters in the atmosphere. The object of the utility model is to improve the accuracy of measurement of meteorological parameters, improving the performance of upper-air radiosonde. To solve this problem an apparatus for measuring meteorological quantities, and form the telemetry signal aerologic radiosonde comprising a humidity sensor, a temperature sensor, two keys, the reference resistor of the timing resistor, timing capacitor, a timer, a nonvolatile memory, analog-to-digital converter (ADC) unit control and processing unit and forming a telemetry signal. The apparatus is characterized in that the frequency signal of the temperature sensor and the reference resistor is digitized by the processing unit and forming a telemetry signal. The voltage of the humidity sensor is digitized by the ADC. It is possible to software implementation, the temperature compensation of the measured humidity value by processing and shaping assembly telemetry signal. The possibility of storing calibration characteristics in the nonvolatile memory. Moreover, keys, nonvolatile memory, ADC, the control node and the node processing and forming the telemetry signal formed on the basis of a programmable microcontroller, thus reducing the cost of the device, to improve the weight and size characteristics, ensure high stability of the duration of the telemetry signal pulses, and also depending on the task It may be formed on the output unit or telemetry signal, or a digital sequence in which the encoded measured meteorological parameters. 1 ab.
