The Design Of System Of Blasting Vibration Wireless Measurement

With the wide application of the high-precision digital electronic detonators in the mining, water conservancy, transport and railways, the digital explosion is becoming more and more popular. The damages caused by the explosion are always the problem, which the science concerns. With the aim of blasting vibration on the remote measurement and monitoring, in the strict control of blasting seismic effect, for wide use of the digital detonators, the system of blasting vibration wireless measurement is proposed. Scientific monitoring and objective analysis of the impact of blasting vibration have the engineering significance.By referenced a large number of documents and analyzed a lot of blasting cases, the solution of blasting vibration wireless system is designed. The system is made of vibration measurable equipment, analysis software, data service and communication network. Using the technology of GPRS and Internet is due to the need of the remote data transmission. However, the large quantities of data are lost in the transmission when GPRS is used. In order to ensure the accuracy of data and increase the rate of transmission, and combining the features of the blasting vibration signal which has the short rising time and the better continuity at last, and researching the common data compression algorism, adaptive data compression algorism is designed.During the process of blasting vibration measurement, the wireless node is placed around the vibration source. The data service is running at the serve which is connected with the Internet. The communication network is responsible for the communication between the measurement and the serve. The wireless node collects the data and transmits to the terminal, and the terminal transmits the data to the specified serve through the data transmit unit. The researchers could analyze the blasting vibration immediately. Simulations show that: the system of blasting vibration wireless measurement realizes the remote data collection, data transmission, and data analysis. The system, integrating a variety of advanced technology, such as electronic technology, network technology, wireless communication technology and software development technology, combing with the theory of blasting vibration analysis, provides the services for the analysis of blasting vibration. It is an innovation for the blasting vibration measurement.
