Description
Technical field
The present invention relates to the remote initiation of commercial electric detonator, be specially the remote initiation control method of commercial electric detonator.
Background technology
Industrial detonator is the detonation element of engineering explosion, nearly 3,000,000,000 of national annual consumption.Mainly contain three kinds of plain detonator, electric detonator and Nonel detonators at present.Plain detonator adopts artificial by sending out igniting, and efficient is low and be absolutely unsafe; Nonel detonator networking complexity and defer time precision are not high.Along with the continuous progress of blasting technique, the consumption of plain detonator is successively decreasing year by year, and the consumption of Nonel detonator and electric detonator is in continuous increase, and particularly the consumption of electric detonator reaches more than 50%.Commercial electric detonator, according to national GB8031-87, defer time is divided into 4 " millisecond series ", 1 " 1/4 second series ", 1 " half second series " and 3 " second series ".The extension series of existing electric detonator is to rely on the prescription and the explosive load of delay powder to determine the defer time constant, and error is very big, is difficult to reach the needs of accurate explosion.Commercial electric detonator generally adopts electric current or high energy priming device to detonate at present.In whole burst region, adopt series connection/parallel way that a plurality of electric detonators are linked together, detonate together.Must use very long lead-in wire to connect into net like this, except that time-consuming taking a lot of work, misconnection also takes place or misses phenomenon in artificial wiring unavoidably.
Concerning single electric detonator, realize that there is not technical problem in remote initiation.As long as wireless signal transmitting device of configuration,, and set up one and got final product by the firing circuit of signal processing apparatus control simultaneously at the electric detonator inner sealing or connect a signal processing apparatus.Wireless signal transmitting device emission time break, after the signal processing apparatus in the electric detonator received time break, the control ignition circuit was connected, and just can realize detonating of electric detonator.Even a timing/delay circuit or electronic timer etc. can also be set in electric detonator.After electric detonator receives wireless time break, through the control ignition circuit connection again of accurate electronic delay,, be used to overcome existing electric detonator and rely on the prescription and the explosive load of delay powder to determine the defer time constant to realize accurate electronic delay, error is very big, is difficult to reach the problem of accurate explosion; Also can make electric detonator regulate defer time arbitrarily, break through the existing fixedly restriction of defer time of electric detonator according to particular requirement.
Certainly, in real explosion, can only not use single electric detonator, and be to use a large amount of electric detonators.As in the directional blasting of building, need place a plurality of electric detonators at the diverse location of building, need simultaneously the burst time of each or every group of electric detonator is done accurately control.The problem of exist actually is, because disturb and reason such as signal attenuation, can't guarantee same frame (individual) time break (the wireless time break that wireless signal transmitting device sends normally is made of multiframe signal) that time break that all electric detonators can both receive that same wireless signal transmitting device sends or same wireless signal transmitting device send reliably.Like this, just can't guarantee the simultaneous initiation of all electric detonators or have synchronous time-delay timing benchmark.And influence the accurate control of electric detonator remote initiation, be difficult to reach the needs of accurate explosion.This also is the main cause that the commercial electric detonator remote initiation does not obtain applying in industrial explosion at present.
Summary of the invention
The present invention can't guarantee the simultaneous initiation of all electric detonators or have the problem of accurately same time-delay timing benchmark in order to solve the commercial electric detonator remote initiation, a kind of remote initiation control method that realizes the commercial electric detonator of the accurate explosion of wireless remote control is provided.
