Commercial means of automatic control system of electricity metering, as is known, are installed on the input switchgear and measure the power consumption of all electrical consumers of this metering facility. Such data do not give a complete picture of electricity consumption on each floor of the metering facility, which in turn does not allow the implementation of energy saving measures. Also, these metering systems for electricity metering have a high cost. The article proposes a method of data processing and transmission to the server with their subsequent analysis of power consumption on each floor of the object under study using the ARDUINO microcontroller. Such an accounting system has a lower cost than an automatic control system of electricity metering industrial production. The article presents the scheme of implementation and types of current and voltage sensors. The topology of the measuring complex is also considered in the article. Such a topology can expand and keep not only the general account of a concrete floor, but also in the generality of each educational audience separately. Collecting such data on electricity consumption, it is possible to conduct a qualitative analysis of rational electricity consumption in the educational process, it means that for example in sufficient natural light artificial lighting in the classroom does not need to be used, or after laboratory tasks in a computer class, computers there is still some time. The introduction of energy-saving housing is performed due to the comparative characteristics of the power of gadgets, laboratory stands, etc. with the number of students in the group in accordance with the approved educational process. The algorithm of data processing, analysis of rational use of electric energy and comparative characteristics are implemented on the university server.

According to the control requirements of campus ringers, a PLC-based automatic control system is realized by using the real time clock function provided by S7-200 CPU224 PLC and the friendly human-computer interaction function provided by TD400 text display. The control system can automatically judge the ringing work mode by the current system time of PLC, that is the summer time ringing mode and the winter time ringing mode. The user can also choose other work modes, such as the college English test mode and the computer grade test mode by pushing the button of the text display. In this paper the composition of the control system, the working principle and the designs of hardware and software are introduced. The system has advantages of friendly interface, simple operation, convenient maintenance, high reliability, strong anti interference ability, which makes it popularize.
