Method and device for monitoring the recordings of plotters, recording devices or other automatically operating writing or drawing installations

摘要

The invention relates to a method and a device for controlling the recordings (1) of plotters, recording devices or other automatically operating writing or drawing installations (SZA), in particular for monitoring the functioning of writing or drawing devices (2) in such installations, at least two measuring units (3) each being equipped with a transmitter (S) and a receiver (E) and, if appropriate, with a light source (LQ), cooperating with a data processing system (4) and being related in space with the writing or drawing device (SZG), a recording and a monitoring process being executed in each case simultaneously and comparisons or balancing of measured values between in each case two measured values of the monitored value of a measurement area of a recording (1) just carried out and the monitored value of a measurement area registered immediately previously being formed. At defined intervals, in each case comparative measurements and comparative calculations are carried out, in each case between at least two measurement signals, referred to the measurement areas (5) assigned to them, the measurement signals being picked up regularly from at least two differently arranged measuring units (3). In the case of a device for this, the writing or drawing device (2) which is in use has assigned to it at least two differently arranged measuring units (3; 31, 32, ...), each of which registers one measurement area (5; 51, 52, ...), in each case one first measurement area (51, ...
