ELECTRONIC LOCK SYSTEM HAVING DAMPPROOF DEVICE, IN WHICH TEMPERATURE SENSOR AND HEATER ARE USED

摘要

PURPOSE: An electronic lock system having a dampproof device is provided to enhance the reliability by preventing previously a dew condensation phenomenon. CONSTITUTION: An electronic locker is installed at a holder of a door frame in order to open or shut a door. An electronic locker module is used for driving the electronic locker. A PCB includes an authentication unit. The PCB is installed within a housing(32). The housing is installed at one side of the door. A temperature sensor(42) is installed in the inside of the housing in order to measure temperature. A humidity sensor(43) is installed in the inside of the housing in order to measure humidity. A fan(46) is installed in the inside of the housing in order to circulate air. A heater(48) is installed in the inside of the housing in order to generate heat. A circuit breaker is connected to the heater in order to interrupt the power according to a temperature level. A control unit(40) drives the fan and the heater when the temperature and the humidity of the housing approach a dew condensation point.
