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 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
