METHOD OF TESTING NAVIGATION DIGITAL INPUT DEVICE FOR INTEGRATION NAVIGATION SYSTEM

摘要

A method for testing a navigation digital input device of an integration navigation system is provided to enhance user convenience by checking rapidly and accurately whether or not the navigation digital input device is in a normal state. Output control instruction is transmitted from an alarm input testing module(5) to a navigation simulator(3). The output of digital output simulator is supplied to a digital input unit(4). A navigation digital input unit transmits inputted digital navigation data as an alarm input result module(2) of an electronic sea map/radar/coning system(1) through TCP/IP communication. The alarm input test module compares the output value of the navigation simulator with the input value of the alarm input result module and checks whether or not the navigation simulator is in a normal state according to the comparison result.
