Description

(54) Involvement of the coordinator's software

The invention relates to the involvement of the coordinator's software.

Until now, the automatic drawing of the drawings was mainly done by coordinator-controlled paper punch tape. The disadvantages with regard to the paper punch tape, the number of records, the lack of paper strength are obvious. Drawing on automated devices in conjunction with a computer is very costly, as it usually blocks the computer due to the longer time it takes to move scribbles on paper. An improvement in this field is the off-line drawing method, which is predominantly made of magnetic tape by means of a tape recorder and an electrical device, a substantial part of which is a decoding device which in itself tends to be a small computer and hence expensive.

These disadvantages are overcome by the wiring of the coordinator software of the reader unit, the buffer, the control unit, the gate switch, the decoder and the gates according to the invention, which is based on the output of the reader unit being connected for eight bits. . The junction for the bit indicating the position of the whistles up or down is connected through the gate to the coordinator's input. The connections for the remaining three bits are connected to a decoder, of which four coordinates for the coordinate signals + X, -X, + Y, -Y are connected through the gate to the coordinator input, where the link from the reader unit is routed to the control circuit and the control circuit is connected by two connections to the gate switch and another connection to the gate. The coordinator is led through the link

The simpler and more cost-effective device will enable the drawing machines to be expanded to many design and engineering offices, freeing up the workforce from repeatable activities and enabling them to devote their own technical creative work.

The method used so far employs an 8-bit word to control the stroke position of a single recorder.

The circuitry of the invention uses an 8aI bit word to control two recorder movements. The DC signal conditioning procedure described below has achieved that twice as many commands for a digital recorder can fit on the same portion of an access medium, such as a magnetic tape, a computer parnet, a disk.

An example of wiring of the coordinator software according to the invention is shown in the drawing. The wiring of the coordinator software is comprised of a reader unit, a buffer, a control unit, a gate switch, a decoder and gates, the output from the reader unit 8 with the eight bit connections being connected via the buffer memory 2 to the gate switch χ. indicating up-down position is connected directly through the gate χ to the input of coordinator 17 and the connections χ for the remaining three bits are connected to the decoder 6, of which four connections 10 for the coordinate signals + X, -X, + Y, -Y are connected via the gate χ to the co-ordinator 17 input, wherein the link ^ 1 of the reader unit X is connected to the control circuit χ ^{and the} control circuit χ is connected to the gate switch 2 ^and the gate 16 to the gate χ; via the control circuit χ and continuing via the connection 12 to the reader unit χ.

From the 8-track magnetic track of the simplified electrical device shown in the drawing, the flush from the χ reader unit, i.e. the tape recorder, supplies the 8-bit word 4, which is stored in buffer 2 after SYNCHR sync pulse arrives at the χχ junction. This is true on condition that the READY signal in link 12 is regular, the device is able to receive the 8 bit word 4. Thus, the READY signal at link 12 controls the removal of each 8-bit word 4 from the reader, i.e., the tape recorder. When 8 bit word 4 is removed, the READY signal in link 12 becomes irregular. At the same time, the SYNCHR pulse in the link 11 sets the control signal χ in the control unit 13 to open the gate switch χ for the bits B 1 to B 3. Three of the four bits χ are decoded in the decoder 6 to the + X, The first bit in the quadruple 4 gives the recorder setup data. These six signals are adjusted to the required pulse width by the HRDL pulse at the link 16, applied to the co-ordinator input χχ.

When the pulses are received in the recorder, a BUSY signal is generated in the χχ connection, which is fed from the coordinator to the χ control unit. The BUSY signal at link 15 is true for the operpoe in the coordinator, controlling the movement of the white or the whistle. The BUSY signal at link 15 cancels the signal at link 13 and sets the signal at link X4 which opens the switch to pass bits B ^ to θ.

These are again decoded in the decoder 6 into individual commands + X, -X, + Y, -Y in the links 10 and the position of the stylus 8.

Once the BUSY signal in link 15 becomes irregular, another HBDL pulse is generated at link 16 which sends additional pulses to the recorder. This again generates a signal in the coordinator

The BUSY in the link J1 and after the BUSY signal in the link J1 is terminated, after the movement in the coordinator, the READY signal in the link 12 is set. Tim is signaled in the reader unit that another 8-bit word can be delivered again. The reader unit may be a tape recorder, a computer disk memory.

The present invention can be used for automatic drawing of drawings, electrical diagrams, diagrams and the like, particularly when using ee to draw repeatable but spatially different elements, as is conventional in the art.
