Development of the Algorithm for Defining Wind Parameters Ultrasonically 000_8.pdf

This paper considers the option of constructing an ultrasonic sensor of wind speed and direction with changing the operating time of sound passage in the atmosphere, depending on the speed and direction of motion of the medium. The variant of placing ultrasonic emitters and receivers allowing to exclude affect of temperature, humidity and atmospheric pressure at the speed of sound is proposed. The paper describes the algorithm which allows to find the wind speed and direction from the data on sound propagation time. The algorithm also allows to determine the wind speed and direction with the same accuracy regardless of the direction of air flow. The sensor described in the article has not any moving parts which improves its reliability and excludes the influence of atmospheric parameters on the speed of sound, that makes it possible to use such device in a variety of climatic conditions and obtain wind speed and direction with the same accuracy.

The Development of the Algorithm for Calibration and Temperaturehumidity Compensation of the Gas Sensor Readout on the Basis of the Stannic Oxide 000_14.pdf

The distinctive features of sensors on the basis the stannic oxide are high sensitivity, simple structure and the relatively low price. The main disadvantage of the sensors is the poor selectivity. Within the research, the gas sensor on the basis of the stannic oxide as a typical representative of the adsorption type sensors is chosen. The article discusses the calibration and improvement in the accuracy of gas sensors on the basis of the stannic oxide that are widely used in systems designated for the gaseous atmosphere composition control. The algorithms for calibration and temperature-humidity compensation of the gas sensor readout are developed. The algorithms allow to calibrate these sensors without using the complex equipment as well as to correct their readout depending on the temperature and humidity of the environment. The developed algorithms increase the readout accuracy of the sensor on the basis the stannic oxide. The proposed solutions are based on well-known approaches to sensor calibration and correction. The solutions also concretize the results relating to the MQ-13type of sensor.

Developing Algoritm of Interaction Between the System for Cargo Condition Monitoring and the System of Cargo Hold Drainage for Prevention of Cargo Liquefying 000_6.pdf

One of the reasons of fleet averages is the inadequate or even missing control system for cargo and gas air environment monitoring in cargo spaces of different-classes ships during the voyage. The main factors to ensure the safety of goods during carriage by sea are heat and humidity transportation regime and ventilation one. The algorithm of interaction between the system for cargo condition monitoring and the system of cargo hold drainage for prevention of cargo liquefying is considered in the article. The variants of systems interfacing are also analyzed. The developed algorithm of integration and analyzed variants of interfacing of these systems allow constructing the control and monitoring system of cargo state in the hold of bulk dry-cargo ship. The exploit of the integrated system should improve the control of cargo condition by the crew and give the opportunity to control and maintain necessary dry and humidity characteristics of hold air and gas environment. It should enhance safety carriage of bulk cargo on dry-cargo ships.
