METHOD FOR DETECTING HAZARDOUS AND NOXIOUS SUBSTANCE COMPRISED IN SEA WATER BY USING ELECTRIC RESISTANCE

摘要

The present invention relates to a method to detect hazardous and noxious substances capable of detecting hazardous and noxious substances flowing in the water by using an electric resistance value, and detecting a hazardous and noxious gas released into the air by evaporating hazardous and noxious substances in water. According to the present invention, the method to detect hazardous and noxious substances comprises: a first step of supplying power generated from a power supply module to a first electrode unit and a second electrode unit equipped in a hazardous and noxious substance detecting part arranged in water, and a third electrode unit and a fourth electrode unit equipped in a hazardous and noxious substance detecting part arranged above the water; a second step of measuring an electric resistance value of the first electrode unit and the second electrode unit wherein power is applied in a first electric resistance value measuring module; a third step of measuring an electric resistance value of the third electrode unit and the fourth electrode unit wherein power is applied in a second electric resistance value measuring module; a fourth step of storing each measured electric resistance value in a storage module; a fifth step of checking whether hazardous and noxious substances exist in the water based on variation of the measured electric resistance value of the first electrode unit and the second electrode unit by a control module, and of checking whether a hazardous and noxious gas generated by being evaporated from the hazardous and noxious substances exists based on the variation of the measured electric resistance value of the third electrode unit and the fourth electrode unit by the control module; and a sixth step of transferring an alarm signal to the central management server through a wireless communication module by generating the alarm signal when the hazardous and noxious substances or a hazardous and noxious gas exists by the control module.
