| Design and realization of system for checking and measuring ground vibration effect in engineering blasting is introduced in this paper. Lots c f technology are adopted ,such as continuously variable slope delta modulation, frequence shift keying, frequency division multiplexing, microwave transmitting, time division multiplexing, phase-locked loop, single-chip computer control, digital signal processing etc. Their work principle and application in this paper are described in detail. By debugging, the system completely reach the goal such as automation, continuance, real time, economization, practicability, conveneience, precision etc. the system has expansive application prospect and marked in the furture. |
