Embodiment 1

[0041] like figure 1 As well as 2 It shows a blasting safety analysis method based on continuous digital vibration, including establishing a standard vibration model and continuous inspection blasting vibration.

[0042] Generate current blasting vibration strength formula

[0043] First detect the currently changing parameter K value and α value, the K value and α value are the environmental coefficient and attenuation index related to the current blasting point to the detection point, including the two methods of A and B, which are specific. as follows:

[0044] Methods A. Set up detecting civil explosive products on the blasting working surface. The detection of civilian explosive products is the same as the current project for the use of civil explosive products. In order to reduce the detection cost, the detection of the explosives of the civilian product is 1-2 units of thunder tubes, digital traces, and explosives of 1-2 units. For the people of the people, the inspection o...

Embodiment 2

[0082] like image 3 Show, an analysis system that uses a blasting safety analysis method based on continuous digital vibration, including data processing center 1 and vibration meter 2. 6. Communication module 7, the processor connects the alarm module 5, the human -machine interaction module 6 and the communication module 7, the communication module 7 between the communication connection between the communication module 7 3 and Standard Create Sub -Module 4.

[0083] like Figure 4 The product model of the microprocessor 9 is STM32F103RCT6. The microprocessor 9 has an information processing submuct 3 and a standard for establishing a sub -module 4. The lattice module function is as follows:

[0084] At least two sets of inspection parameters received by information processing submissions 3 are passed to the standard establishment submissile 4, standard establishment of sub -module 4 receiving detection parameters and calculating the current blasting vibration strength formula thro...

Abstract

The embodiment of the present invention discloses a blasting safety analysis method and an analysis system based on continuous digital vibration measurement, including using method a or method b to generate a current blasting vibration intensity formula; input blasting process parameters, and calculate the corresponding blasting delay interval The expected blasting intensity threshold of , establishes a sequence corresponding to the time-vibration intensity, and obtains the standard blasting vibration model; after the blasting starts, continuously collect D 实 The actual vibration velocity at the blasting time point is obtained, and the actual vibration velocity is compared with the expected vibration velocity threshold at the same blasting time interval. Abnormal explosion time point. The present invention can accurately obtain the change parameters of the current environment, calculate the blasting intensity threshold value, compare whether the actual blasting intensity after blasting is qualified, and accurately infer whether there is a blind shot.

Description

Technical field [0001] The embodiments of the present invention involve the field of civil explosive vibration measurement technology, and specifically involve a blasting safety analysis method and analysis system based on continuous digital vibration measuring. Background technique [0002] The project blasting is large at a time. In order to achieve a good blasting effect and reduce the blasting vibration, general blasting is generally segmented, and a delay delay is adopted. During the blasting process, due to some uncertain factors, blind guns may occur during the blasting process. After blasting the blind cannon, it is easy to cause accidents, and the traditional blind artillery recognition method is mainly judged by the experience of staff. There are many loopholes in this method. As a result, it is often difficult to accurately reflect the actual situation. Therefore, studying a practical, fast and reliable blind artillery identification method has great practical signific...
