The electro optical transducer with changeable emission color depending on air temperature, which is destined for fish additional feeding with mosquito larvae, has been designed. It is the effective device of electrotechnics of ecological fish additional feeding with live feed
Solar collectors of helio water heater with ramified surface were developed. We have made an energy estimation of helio unit construction and enhancement of the efficiency of its work because of multiple reflections of solar fluxes
We have made energy estimation of absorbed solar fluxes with a glance of diffuse insolation which passes through double- glazing unit to the right-angled planar radiator. While designing the model it was conceded to assume that direct solar radiation is the radiation of a point source
The article deals with the system, providing
automatic control of the solar water heating system
with the abilities to store in internal memory and to
transmit by the cellular network the information
about the conditions of the plant and the occurring
failure conditions. The common principles of the building the automatic system with the modular
principles are shown. The article solves the issue
about the quality of the water supply through the
quality parameters which provided by the considered
system. The methods of the active and passive loss
minimizing of the heat of the water in the tank are
shown. The usage of the active loss minimizing
system was considered. The block-scheme of the
implementation of the automatic system with
described abilities are shown. The compulsory and
auxiliary blocks of the automatic system are shown.
The algorithm of the checking of the water supply
quality parameters was presented. The study
considers methods of the storing of the parameters of
the working conditions of the plant and the occurring
failure modes as well as the remote information of the
attending personnel by the cellular networks. The
advantages of the conducting of the system log are
shown. The preliminary calculation of the memory
capacity for storing the system log was completed.
The advantages of the described automatic system
with relation to the constructing, controlling, service
and research of the described solar water heating
systems are shown
The procedure of combined electrooptical processing
which allows to disclose the reasonable energy and
technological conditions of seeds’ treatment and to
define the main factors which influence such seeds’
sowing qualities as: germinating power, germinating
ability and length of sprouts is used in this article.
Besides, the procedure allows conducting the research
of efficiency evaluation of some rational parameters
and conditions of treatment which influence
their yield characteristics in field conditions. The
research task was to obtain the data about the number
of spring barley called “Ratnik” shoots and their
productivity depending on the number of working
volume converter’s lamps (1-6) and on the protectant’
norm percent (1-100). The experiments have been
carried out and the data have been obtained for this purpose and the processing of these data has given
the regression equation of the second order writing
the process with the volumetric graphical interpretation.
The rational parameter space of presowing
treatment providing maximal germination and crop
capacity of barley “Warrior” has been obtained on
basis of the diagrams’ analysis. As the growth of
germinating ability and crop capacity is observed
when the number of working lamps is increased the
double spreading at 6 working lamps should be recommended.
The concentration of the protectant practically
ceases to influent the crop capacity. According
to the results of the research there has been drawn a
conclusion that preliminary seeds treatment, for the
purpose of plant diseases preventing, restrains the
germination processes at the initial level. It happens
in connection with conditions deterioration of moisture
access to seeds which are covered with protectant
film. Further processing of treated seeds by optical
radiation promotes the growth of germinating ability
and length of sprouts compensating negative effect of
treatment
The solar power stations for energy supply of remote technological processes making requirements to their design have been designed. Energy estimate of power stations design for remote agricultural consumers has been made
The article deals with the necessity of the uninterrupted
control of the work quality of the solar heating
system. The advantages of the microcontroller systems,
which gave their evolution in the last years, are
shown. The possibilities of the usage of the microcontroller
systems for carrying the work quality control
are shown. The electrical principal scheme of the
system of the automatic control of the solar water
heating which allow to control the work quality control are shown. The system was divided into interconnected
parts. The methods of the temperature control
by the electronic temperature sensors 18B20,
water control by the optical pair with open channel
and water quantity meter with the optical wheel, water
level in the tank by the ultrasonic sensor of the
distance and level of the solar radiation by the pyranometer
are shown. The necessarily calculation of the
geometric tank sizes and water velocity in the solar
collector are carried out. The corresponding hardware
resources of the PIC microcontrollers like hardware
counters, timer with the ability to allow counting by
the external signal (Gate Control), analog-digital
converter and fixed voltage reference module are
described. The algorithms of the control of the water
temperature in the tank and the control of the filling
the tank with the hot water from the solar collector
are described. The methods of the transmitting information
to the operator are shown. The advantages of
the microcontroller control are described
