Access control system in a higher education institution
Access control systems (ACS) currently available on the market are presented as universal. Initially,
they were developed without taking into account the specifics and problems of universities. Moreover,
they are self-sufficient and can be deployed and implemented without any integration with the corporate
information system (CIS) of the university. Many business processes of the university are built on
the assumption that the ACS operates with actual data during the deciding on admission.
The access system of the university when making a decision on admission should have up-to-date
information on the financial balance of residents and students on a contractual basis, acting as a powerful
tool that improves financial discipline, and reduces payment arrears. Development of the ACS as
an integral part of the university’s unified information system is a relevant objective.
The architecture of the ACS of the university in terms of software can be implemented as a centralized
or distributed one. In a centralized architecture, the ACS software is installed on a dedicated
server, in a distributed architecture — directly to controllers (microcomputers). The article discusses
the advantages and disadvantages of the centralized and distributed ACS architectures, it is shown that
the developed ACS contains elements of both architectures.
A library for reading electronic cards using the wiegand protocol is presented. The process of controlling
the turnstile from the microcontroller point of view is described. The scheme of interaction
of microcomputer and microcontroller is given. The mechanism of controller data synchronization
with the central database is considered. The ACS presented in this article was introduced in 2013 and
is now successfully used at the Moscow State University of Food Production, as well as in several
other universities.
At the moment of this article publication there are about 23 million records in the event log, 72 access
control devices (turnstiles, auto barriers, electronic locks) are registered in the territorially-distributed
system. Based on the results of its deployment, the management stated the increase in the efficiency
of the university’s work in a field of personnel discipline, business processes integration, and
time savings due to ease of use.
