DEVICE AND METHOD FOR RELAY CONTROL OF SECURITY EQUIPMENTS

摘要

PURPOSE: A device and method for relay control of security equipments is provided to reduce electricity waste by using a two coil latching type relay and decide whether to bypass using set and reset controls. CONSTITUTION: A device and method for relay control of security equipments includes the following steps. A two coil latching type relay for bypass supports switching to bypass mode for bypassing input data according to the activation of set coil and the switching of a processing mode which encodes and decodes data that are inputted. A single side stable type relay(130) switches according to the power supply so as to submit electricity to the set coil. A two coil latching type relay for control(140) switches according to the pulse signals from the external power supply. A transistor set controls the flow of electricity of set coil submitted to the power supply. A transistor reset controls the flow of electricity of reset coil. The device enables users to reduce electricity waste by using a two coil latching type relay and decide whether to bypass. The device will enhance the stability of security equipments.
