Study of an Access Monitoring and Control System Working in the Presence of Electrostatic Discharges

Resumo

Functioning of an access monitoring and control system is experimentally studied in the presence of electrostatic discharges. Several types of malfunctions of the functional units of the system related to the effect of noise of electrostatic discharge are revealed. Mathematical models are proposed for evaluation of electromagnetic noise in communication lines of the access monitoring and control system in the presence of electrostatic discharge. A few methods for an increase in the noise immunity of the access monitoring and control system in the presence of electrostatic discharge are proposed and analyzed.
