A method of transmitting information of a heavy equipment vehicle for construction, in which a plurality of slave vehicles having slave communication equipment mounted thereon, master communication equipment capable of communicating with the slave communication equipment of each slave vehicle or a master vehicle having the master communication equipment mounted thereon, and a server capable of communicating with the master communication equipment are provided, and information of each slave vehicle is transmitted to the server through each piece of the slave communication equipment and the master communication equipment, and control information of the server is transmitted to each slave vehicle through the master communication equipment and each piece of slave communication equipment, the method comprising: identifying whether data to be transmitted by the server is the same data to be transmitted to the all of the heavy equipment vehicles for construction; when the data to be transmitted by the server is not the same data to be transmitted to the all of the heavy equipment vehicles for construction, generating a data set in which a unique identification number of the corresponding heavy equipment vehicle for construction is added to the data; when the data to be transmitted by the server is the same data to be transmitted to the all of the heavy equipment vehicles for construction, transmitting the data to the master communication equipment by the server; and identifying whether the data set of all of the heavy equipment vehicle for construction is received by the master communication equipment; and when the master communication equipment is not present, and a communication signal, through which communication is available with the server, is not received, identification of a signal and standby are performed until a transmission available state is ready, and wherein the data set includes a unique identification number of the corresponding heavy equipment vehicle for construction. identifying whether data to be transmitted by the server is the same data to be transmitted to the all of the heavy equipment vehicles for construction; when the data to be transmitted by the server is not the same data to be transmitted to the all of the heavy equipment vehicles for construction, generating a data set in which a unique identification number of the corresponding heavy equipment vehicle for construction is added to the data; when the data to be transmitted by the server is the same data to be transmitted to the all of the heavy equipment vehicles for construction, transmitting the data to the master communication equipment by the server; and identifying whether the data set of all of the heavy equipment vehicle for construction is received by the master communication equipment; and when the master communication equipment is not present, and a communication signal, through which communication is available with the server, is not received, identification of a signal and standby are performed until a transmission available state is ready, and wherein the data set includes a unique identification number of the corresponding heavy equipment vehicle for construction.
