The invention provides an initiation device, which comprises a control module, a man-machine interaction module, a signal modulation sending module, a power management module, a signal demodulation receiving module, a signal bus and a power supply, and particularly, the initiation device further comprises a computer communication interface, wherein, one end of the computer communication interfaceis connected with the power management module, and the other end thereof is connected with the control module. The invention further provides blasting network information transmission procedures for the initiation device, which comprise the following steps: firstly, switching on the computer communication interface; then, waiting for receiving an external instruction sent in preset time T: packaging and uploading the read blasting network information if the external instruction is a network information upload instruction; and downloading a blasting network information from external, unpackingand preserving if the external instruction is a network information download instruction; and finally, closing the computer communication interface. The computer communication interface can be a serial interface, a parallel interface, a Bluetooth interface, an infrared interface or a USB interface. The technical scheme realizes the function of interacting the network information between the initiation device and the external.
