METHOD FOR EXCHANGING DATA BETWEEN A DEVICE FOR PROGRAMMING AND TRIGGERING ELECTRONIC DETONATORS AND SAID DETONATORS |
摘要 |
Explosions are carried out in the mining of raw materials, whereby explosive charges are placed in numerous boreholes and are detonated in succession, according to a specific time frame. The electronic detonators (4a - 4c) of t he explosive charges form an ignition system. Said electronic detonators are jointly connected to a programming and triggering device using a bus line (3 ). However, this leads to communication problems between a detonator and the programming and triggering device (2) in that the remaining detonators which are connected to the bus line present capacitive resistances which affect th e transmission of the data. According to the invention, a direct current of a predetermined duration, which is greater than the current provided for generating signals, is applied to the ignition circuit (1) before an intende d communication of a detonator with the device. The signals used to generate t he data which is transmitted by the detonator as a response are subsequently generated with a lower current than the previously increased direct current and the direct current is increased again prior to the response of another detonator.
