Abstract: Provided is a remote control method of a snow removal system using a smart phone, which remotely controls the system installed at a site while checking conditions of a road and the system in real time when improvement of a road surface is needed because a condition of the road surface deteriorates due to dusts, yellow sand, frozen snow on the road surface, etc. The remote control method includes: accessing a remote terminal device in real time; allowing the access of the authorized manager using the smart phone; transmitting data; driving a CPU of the remote terminal device with SMS data to output a data value; stopping operation of the pump; comparing data input or output values stored and set in the CPU and a memory; determining whether to continuously perform a current operation; obtaining collected information; and feeding back all of the processed results to the smart phone.

Abstract: A composition for a non-chloride based and less corrosive liquid type deicer is provided. The composition includes: potassium acetate of approximately 10% to approximately 20% by weight; disodium succinate of approximately 3% to approximately 10% by weight; dipotassium succinate of approximately 1% to approximately 5% by weight; ethylene glycol of approximately 5% to approximately 10% by weight; ethanol of approximately 5% to approximately 15% by weight; and an aqueous polyvinyl alcohol solution of approximately 40% to approximately 70% by weight. Such composition of the liquid type deicer is environmentally friendly by not containing chloride ions (e.g., non-pollution in soils), and is cost-effective due to an elongated reaction time by remaining continuously on snow/ice surfaces. Also, the composition of the liquid type deicer can be conveniently storable and easily sprayed, is not being re-frozen while being capable of removing snow/ice, and can replace expensive imported deicers.
