Definitions
- the invention relates to a method for comparing the sensitivity of a optronic detonator according to the preamble of claim 1.
- Optronic detonators are, for example, in DE 24 56 162 C2, in DE 26 08 066 C2, in DE-PS 27 14 766, in DE 39 18 243 C2 and in DE 39 27 819 C2.
- Such optronic detonators have the problem that they need to be matched if they have a narrow sensitivity range must adhere to.
- the overall sensitivity is determined by the performance of the transmitter, the sensitivity of the receiver and by the gain the amplifier device of the optronic detonator. Should the optronic Igniter - as stated above - a narrow target sensitivity the total sensitivity limit must not be due to any combination of transmitter, receiver and amplifier be crossed, be exceeded, be passed.
- the sensor of the optronic igniter must be installed and in Operation. This means that a comparison in the production chain the optronic detonator can only be carried out very late. To this comparison is it is necessary that the envelopes covering the components only partially are applied or that these protective coatings are completed manually Need to become. Through this activity, i.e. by manual application, i.e. Complete the coating, by manual assembly and through Quality assurance incurs relatively high costs.
- the invention is based on the object to create a method of the type mentioned, in which the above described defects are eliminated.
- the invention has the advantage that for systems equipped with intelligence are instead of a fixed, i.e. predetermined amplifier chain, one digital programmable amplifier or a digitally programmable attenuator are used (VGA).
- VGA digitally programmable attenuator
- the said, equipped with intelligence System it can be a controller with flash memory.
- the controller is compared with that for the respective optronic Igniter optimal gain is programmed.
- the controller when compared with an operating software that loads the VGA to a medium Gain setting.
- the optronic fuse is in Set and the signal levels achieved, i.e. the sensitivity, measured. From the measured sensitivity value, the ideal gain of the VGA can be calculated.
- the controller can then use the target gain can be programmed.
- the method according to the invention has the advantage that an analog adjustment e.g. by laser trimming, is not required. Another advantage is that possible aging the sensors of an optronic detonator at any time by reprogramming can be compensated. According to the invention, it is therefore possible a desired constant sensitivity for the serial production of optronic detonators to guarantee.
