Detonator network detonation control method

Abstract

The invention discloses a detonator network detonation control method, which comprises the following steps that: firstly, a detonating primer transmits an instruction to a time delay firing device, wherein the instruction is used for setting a detonation delay time counting value of the time delay firing device and detecting the connection reliability between the time delay firing device and the detonating primer and sequentially comprises an orientation part, an address coding part and a delay time part; subsequently, the detonating primer determines a time reference for delay counting of the time delay firing device; and finally, the time delay firing device accomplishes the delay time counting according to the delay time counting value and the time reference, and then a detonator is detonated. According to the detonator network detonation control method, the precise delay timing for detonation of the electric detonator is realized, the detection on the connection reliability of the time delay firing device is realized, the accuracy in data decoding of the time delay firing device is improved, and the vibration waveform of detonator network detonation is prevented from being influenced by delay time setting errors caused by decoding mistakes.

Description

technical field [0001] The invention relates to the application field of pyrotechnics, in particular to a detonation control method for a detonator network. Background technique [0002] An electric detonator is an industrial detonator that explodes by converting electrical energy into heat energy. It is made of a fire detonator and an electric ignition element. It is generally used in blasting operations in places with gas, coal dust or other combustible dust explosion hazards, and is also widely used in various blasting projects such as general mining, digging tunnels, building roads and bridges, and building water conservancy. In the blasting network, multiple generator detonators are connected in series, receive the high-voltage pulse signal sent by the electric detonator detonator to ignite, and realize the delayed detonation according to the delay body inside the detonator. [0003] A magnetoelectric detonator is a detonator excited by electrical energy generated by e...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned detonators control the delay time through the length of the internal delay charge, the delay accuracy is poor, and the delay charge contains a large amount of lead, which will cause certain lead pollution during the use of the detonator

[0005] In addition, after the existing detonators are networked, as long as they receive the high-voltage detonation signal sent by the external detonator, they will start to start and then complete the detonation, which has low safety.

At the same time, in the existing detonator network, because it is impossible to detect the connection reliability of the detonator in the access network, there is a phenomenon of blind fire of the detonator caused by the unreliable connection of the detonator, which further reduces the safety of the use of the detonator
