The present invention relates to an integrated business 
processing system in which a conventional Internet 
web server-based unidirectional 
remote control system can be improved to a bidirectional PC 
remote control system in a one-to-one PC access state, a variety of functions, such as a table for writing letters and drawing figures, etc., can be added, and a variety of business 
processing can be smoothly performed through the association of a 
client PC system, a consultant PC system, a 
franchise head office system, an assistant business PC system in terms of a business task, a construction site business 
processing PC system, an custom-built and material development PC system, a company head office warehouse and factory PC system, and a 
developing country production factory and export / import management PC system, which are based on a unidirectional or bidirectional PC 
remote control business processing system. To this end, integrated business processing system using a bidirectional PC remote control base, wherein a 
client PC of an Internet PC remote 
control system including a PC main body and a general monitor connected to the PC main body, and a consultant PC of 
the Internet PC remote 
control system including a PC main body and multiple monitors of a main monitor and an auxiliary monitor having a 
liquid crystal tablet or a general tablet, which is connected to the PC main body and is capable of performing two or more writing and drawing functions, are connected using communication means of wired / 
wireless wires or 
satellite Internet, and a remote control 
client module, a remote FIP client module and a remote CHAT client module are constructed for the remote control, and are adapted to analyze a corresponding protocol and distribute and transmit each thread through a TCP / IP communication port, wherein the consultant PC first opens a consultant access administrator window of the PC remote 
control system, displays the consultant access administrator window on the monitor, and informs the client PC of a remote access request using a general telephone, so that the client PC can make access through a client adaptor or an access program through a website; and after a client is accessed through Internet remote control by clicking on a client access menu of 
the Internet remote control system base, the client PC remotely accesses the client PC and remotely accesses the consultant PC by manipulating the PC main body of the client PC under remote control authority.
