Abstract
The policy of energy saving provides development of the highly effective automated systems of accounting of power consumption. Research objective is increase in efficiency of development, introduction and further operation of the automated systems of accounting of power consumption by justification of structure of such system in the conditions of the public and budgetary institutions. The analysis of features of operating conditions of the automated systems of accounting of power consumption in the conditions of budgetary institutions, in particular allocation of the existing standard restrictions and available resources is carried out. Features of functioning of system in such objects are allocated and analyzed. A big variety of models of the operated metering devices of energy resources, rather wide use on subjects to connection to Internet network, high probability of essential dispersion in space of the locations of metering devices is noted. The conceptual principles of development of the block diagram of system are formulated. The relevance of use modular structure of the device, support of several technologies of data transmission to the server, supports of wireless technologies of communication, use of modern element base with advantage of the most integrated solutions is proved. For an illustration of the offered concept the structure of system on the basis of the popular microcontroller for the Internet of things (ESP8266) with the built-in support of the WiFi interface is offered. By the principle of modular creation of the device it is separable a basic unit which will include the microcontroller, the power supply unit, the rechargeable battery, the module of real time clock and the RS232 converter as the most often used communication interface for metering devices. High extent of integration, realized by developers in ESP8266 provides a possibility of connection of sensors (temperature, humidity, pressure, etc.) and other peripheral devices (or additional modules) on the most popular SPI, I2C, UART interfaces, directly to the microcontroller. The most economic means of communication with the central server of system is the IEEE interface 802.11 b/g/n (WiFi is built in ESP8266) which can work with the usual WiFi router which is already available on an object. The concept provides increase in efficiency of development, introduction, flexibility of control and the subsequent operation of such system due to the maximum use of the ideas of IoT technology, use of available resources and accounting of typical features of an object of automation.
