Remote control method for snow removal and disaster prevention system using smart phone

A method of remotely controlling a snow removal system using an external case (107), in which a body (103) storing a spraying agent (102), a pump (105), and a nozzle (106) are installed, a remote terminal device (200) that is installed in the external case (107) and recognizes SMS data to be driven, and a smart phone (500) that includes an application (501) for transmitting and receiving a data value in connection with the remote terminal device (200), the method comprising:

• accessing a mobile communication network (400) with the smart phone (500) to access the remote terminal device (200) through a data communication unit (201) in the snow removal system installed at a site in real time;
• determining whether a user accessed through the accessing is an authorized manager, and, when it is determined that the accessed user is not the authorized manger, blocking the access to the smart phone to allow the access of the authorized manager using the smart phone;
• transmitting data by using the smart phone (500);
• driving a central processing unit (CPU) of the remote terminal device (200) with SMS data, transmitted through the transmitting, to output a data value;
• driving the pump (105) installed at the site to spray the spraying agent (102) through the nozzle 106, or stopping operation of the pump (105) to stop the spray of the spraying agent (102);
• determining whether to spray the spraying agent (102) according to whether the pump (105) is driven, and comparing data input or output values stored and set in the CPU and a memory of the remote terminal device (200) to transmit detection information to the manager;
• checking a data value, transmitted through the transmitting, with contents displayed by the smart phone (500) to determine whether an error occurs, and determining whether to continuously perform a current operation according to the determined result;
• obtaining collected information to check an overall state of the remote snow removal system to input and transfer necessary contents as SMS data by using the smart phone (500);
• and
• feeding back all of the processed results to the smart phone (500).
