DE3241623A1 - Automatic time recording system for documentation purposes, with manual speech output - Google Patents

Abstract

The automatic time recording is carried out by the fully automatic recording of the respective time criteria onto the sound medium by means of a speech generator with processor control. In addition to the useful signal, the time criterion of the respective recording time is also recorded onto the sound medium. A temporal reconstruction of a defining procedure is thus possible at any time, in any place and without ancillary equipment, and specific recording points are more easily and quickly located. The system operates fully automatically in two modes (serial and parallel recording) and is thus suitable for any recording frequency. The recording and reproduction of the time criteria are independent of the quality of the sound medium used and, provided that useful signal recording is still possible, the time criteria are also always completely and reliably recorded and reproduced.

Description

Description of the automatic time recording system for documentation purposes with manual voice output The device I developed is a time recording and documentation system that can be used to document the time of telephone calls, radio messages, etc.

The automatic time recording is done by speaking the given time with or without date by a speech generator with microprocessor control on the tape.

For the first time, this type of recording makes it possible to listen to the Recording with any tape recorder, anywhere, without any additional devices, so that a temporal reconstruction of the documentation in Icürzester and for each Time is possible.

Due to the fact that the time information on the tape is unencrypted is recorded, certain assemblies are omitted here, e.g. in the case of a recording by frequency modulating the decoder to recognize the recorded information i.e. to be able to read, or the error accuracy equals for wow and flutter caused by Slippage or wear of the drive parts can occur. Just as much a source of error is a bad frequency response of the current Zeitdolturnationssystemen Tape recorder, such as that caused by wear and tear or by a partly already light one Soiling of the speaking head can occur.

Based on these points of view, the system I developed can be can be manufactured at a significantly lower price than existing systems. aside from that all of the above error features are excluded with this new type of recording.

This time recording system offers the following recording options the time or date given: 1. When documenting conversations with low Traffic volume offers the option of the time / date after the conversation to automatically record onto the same tape track (recording after completion of the respective conversation = serial recording).

2. Offers in discussion groups with increased or high volume of traffic as a second option, the time / date on the second or further tracks to be recorded automatically (recording parallel to the respective conversation = Parallel recording).

3. Manual entry is possible in both cases by pressing a key.

Listening in is possible via the device's own loudspeaker.

Circuit description: The activation of the automatic time recording and documentation system is taken over by an Akustomat, which the tape recorder if there is a useful signal (here: conversation to be recorded, etc.) in his The running function is switched on and the tape recorder is switched on again at the end of the call a pause position switches. The switching status of the Akustomaten in the evaluation logic-coupled with IC 1 to IC 3 ;. IC 1 and IC 3 are designed as Schmitt triggers for the subsequent circuit to get the corresponding switching edges. IC 2 is used again as an inverter, see above that the switch # 5 1 has the real and the reciprocal switching status of Akustomaten is attached. Depending on the position of switch S 1, the following is now Switching when switching off or when switching on the acustomat is stimulated.

IC ß to IC 11 is an electronic switch, which is also through the selected state on switch S1 / S 2 the speech generator over a monostable Automatically controls the multivibrator.

The relay is controlled by the transistors T 1 / T 2 via IC G / IC 7, which the tape recorder switches in its running function independently of the acustomat.

This is with the switch position "Series recording (see circuit diagram) but only possible as long as the IC 8 has an H level at both inputs. pre-condition this is that there is no Nf at the Nf input of the switchover or coupling module. If this is the case, the Nf is registered via the threshold switch; his exit assumes H level, so that IG 5 / IC ß blocks the start pulse for the speech generator and there is no switchover to the time announcement.

Used during a running time announcement for series recording a useful signal at the Nf input of the time recording system through the threshold switch registered, the time overlay is switched off via IC 5 / IC 6 and the useful signal recorded. This ensures a complete recording of the useful signal as well guaranteed with this type of recording.

The voice output is supported by the voice output chip TMS 5100 (option the time / date recording) or the voice output chip for 7-segment display direct control UAA 1003 (only time recording) enabled. These two systems are in the speech output module housed. The control to these chips is located in the flush-mount block. From the Clock processor, the time information is transmitted to the uP- ~ brick by means of ßCD code.

In the case of parallel recording on a second or further track of the Tape recorder, one input of the OR link of the IC 5 is set to H level, which disables the above function of the threshold switch and the time announcement can also be carried out during a useful signal recording, with this type of recording the useful signal is only transmitted through the switchover and coupling component via the in my case built-in G-Mos analog switches passed through without interference; it the time / date is simply put on the tape track provided for this purpose at the beginning and then at certain intervals for the duration of the recording of the useful signal faded in. The display is activated by a pulse from the clock to the voice output module z.ß. every 15 sec., 30 sec. or controlled by a minute pulse.

Description of the threshold value switch: The incoming Nf is transmitted via IG 11, R 11 switched to the operational amplifier and amplified by this.

Decoupled via IC 12 and fed to diodes D 11, D 12 via R 15, the negative part of the Nf is short-circuited to ground via the D 12, and the positive portion passed on over D 11.

As soon as a DC voltage is applied to R 16, T 11 becomes conductive and opens with its emitter current T 12, whereby the collector voltage at T 12 assumes DV and thus the Schmitt trigger in IC 101 sets its output to H level.

With this circuit, the sensitivity can be set via R 12 and the R 17 the follow-up time can be set.

Description of switching and coupling module: Via the inputs 10 and 3 and the NAND link, the C-Mos analog switches are controlled.

The time / date to be recorded is applied to connection 2.

Connection 1 connects directly to connection 11 of the threshold switch tied together.

Connections 5 and 6 set the flkustomat during the time display in the case of serial recording out of order in order to avoid mutual influencing of the To prevent acustoma and time recording.

The Nf (useful signal) to be recorded is applied to connection 9.

The time is displayed via connection 8/2 in the case of parallel recording.

Connection 8/1: useful signal / time recording with serial recording.

With parallel recording, only useful signal.

Connection 4/7: Implementation of the control of the tape drive.

The time recording system has been used successfully for about 5 months Documentation of radio messages and announcements used.

The basic application of this type of documentation (time recording through speech output modules or computers with speech output options for documentation purposes) represents a new and simpler solution than current documentation systems and, like the circuit presented, would therefore have to be examined for patentability.

Due to the construction of the time recording and documentation system A connection to any tape recorder with a remote media connection is possible.
