The invention relates to automation and computer technology and can be used in software-controlled devices for mounting electronic equipment.

The purpose of the invention is to extend the functionality by monitoring the installation for the presence of false links.

On the flowchart of the device; Fig. 2 is a block diagram of the resolution: readout.

The wrap-up device contains a punched tape reading unit 1, which consists of a punched tape reading mechanism 2 and a control unit 3, a mode setting unit 4 consisting of AND 5, a single-oscillator 6 and a discriminator 7 of duration, a key 8, an EXCLUSIVE element OR 9, first register 10, .first decoder 11, block 12 elements AND,. the second register 13, the second address decoded 14, the display unit 15, the read resolution block 16, the resolving potential driver 17, the mounted block 18, the mounting mechanism comprising the actuator (mounting gun) 19 and the mounting error protection circuit 20 OR 21 and the third decoder 22 display.

The read resolution block 16 contains inverters 23, -23 "and NE-elements 24, -24f, according to the number of mounted contacts, as well as the load element 25 and the power source (+ UnMt)"

The presence of false communications. If there is a false connection between the two monitored contacts, then a zero signal appears at the output of block 16 and the next information frames will not be entered with the addresses of the next circuit, and at block 15 the addresses of the contacts between which there is a false link will be displayed. After its removal, the control of communications will be continued in automatic mode 2 Il.

The inputs of the inverters are one of the inputs of block 16, and the outputs are connected to the first input of the corresponding AND-NOT element. The second inputs of the NAND elements are other inputs of the block 16 The outputs of the NAND elements 24, 24 and 24 are combined, are the output of the read resolution block 16 and 0 are connected via the load element 25 to the power supply (+ Ur, T-).

The wrap mounting device works as follows.

In the installation mode, the key 8 at the control input of the control is transferred to the position at which. its output is constantly present potential installation mode such as a single potential. Suppose that after the previous connection has been mounted, the output signal of the one-shot 6 is formed by an enable signal, which through the OR 21 element is fed to

block 1 input. The information frame with the start address of the communication goes to the corresponding inputs of the block of 12 elements AND. At the same time, at the first output of block 1 there is an allow signal that goes to one of the inputs of the 12 elements block I. The information frame with the start address of the z comes through register 10 to the decoder 11 and through the block 12 elements I to register 13, and then to dec5 encoders 14 and 22. At the same time, the resolution from the first output of block 1, present only at the input of the information frame with the address

start of communication, through the element OR 21 enters the input of block 1. The second information frame is read from the end address of the same communication and entered into the register 10. At the same time, the block 12 of elements AND is blocked by one input from the first output block 1, and, therefore, register 13 stores the starting address of the connection to be mounted. The display unit 15 simultaneously indicates the addresses of the beginning and end of the communication of the mounted connection. At the same time, from the output of the decoder 11, the address of the end of the communication goes to the corresponding inputs of the imaging device 17, at the output of which, for example, (output p.), A resolving potential appears. Since each contact of the mounted unit 18 is connected to the corresponding output of the driver 17, then only on the contact chosen by the former 17 there is a resolving potential. For this scheme, this is a low level potential, i.e. null The installer monitors the communication at two addresses indicated on the display unit 15. At the same time, it must always begin installation from the second information address, since the permissive potential appears at the end of communication address. When installed at the communication start address, the permissive potential is present on the spout of the mounting gun via the mounted connection. Let us suppose that it is necessary, according to a program, to make a wiring connection between parameters and parameters. The installer installs a mounting gun on the contact p, whose address is indicated on the display unit 15 and on which, after inputting information frames with addresses, beginning and end of communication, there is a resolving potential from the nth output of the driver 17 (output) and installs the first end wires At the same time, the output signal of readout resolution block 16 does not change and is a high level signal. Consequently, at the output of the EXCLUSIVE OR 9 element, the potential is zero. When installing the mounting gun on the contact to the resolving potential with the bores of the driver 17 through the mounting connection is fed to the input of the block 16 - the input of the inverter 23 k and from its output to the first input of the element AND NOT 24 j.

Since at the other input of block 16 — the second input of the IS-NOT 24 element, the resolving (single) signal B from the output of the decoder 14, corresponding to the communication start address, is missing, then the output of the element., That is, the output of block 16, there is a zero level resolving potential which

Q arrives at the first input of the EXCLUSIVE OR element 9, In this device diagram, the inverters 231. 23 C; and 23n, as well as elements AND-NOT 24,, 24. and 24 are positive logic circuits5 i. e. the logical culture is a low (zero) level, and the logical one is a high level potential. Consequently, at the output of the EXCLUSIVE OR 9 element, a single signal appears, which arrives at the second input of the AND element 5, at the first input of which, after the input of each previous information frame, there is an allowable signal (single)

5, the potential from the second output of the unit 1. At the output of the element 5, a single signal is generated, which is input to the discriminator 7 of duration. The discriminator 7 of duration generates the output signal only if the signal at its input is continuously present for a certain time determined by its own parameters of the discriminator, and can be performed, for example, on the basis of an integrating chain and Schmidt trigger. The timing of the discriminator 7 is made with taking into account the dynamic properties

d the entire device. The discriminator's output signal triggers the one-oscillator 6, the output signal of which is the output signal of the mode setting unit 4, and is fed to the second one.

, - input element 1-SHI 21. Thus, the input signal of the next two information frames with the addresses of the beginning and end of the communication at the input of block 1 appears only in the case of a reliable installation of the previous connection. The further installation process is similar.

If the connection between contacts where program communication is required,

g is absent, then at the output of block 16 there is no enabling signal and the element AND 5 is blocked, since the output of the element EXCLUSIVE OR 9 has a zero signal. Therefore, input

the addresses of the beginning and end of the next link do not occur until noKSi mount the required communication by the program.

in the control mode by mounted links, the position of the key 8 does not change. In this case, information frames with the addresses of each subsequent communication are entered only in the case of n; 1, the reliable installation of the previous communication.

If between the two contacts there is no connection required by the program, then at the output of block 16: read permission there is no enabling signal. Information frames are not entered with the next link addresses. The installer must install the required communication to the addresses indicated on the display unit 15. Further control over the installed links continues only if there is a reliable installation of the previous links required by the program,

In order to continue the incomplete installation of the unit, it is sufficient in the installation mode (control by mounted connections) to reach the missing connection and then install: to the addresses indicated on the display unit 15.

In the monitoring mode for the presence of false communications, the key 8 is transferred to the control input of the control in such a position that its output always has a zero potential. Block 1 reads from punched tapes reads information frames from punched tapes containing addresses, there should be no contact between which links. As in the editing mode, after reading an information frame with the start address of the circuit, I allow the signal from the first output of block 1 through the OR 21 element is fed to the input of block 1, the second information frame is read with the end of the circuit. If there is no connection between these definable contacts, then a single potential appears at the output of block 16, and a single signal is formed at the output of the EXCLUSIVE OR 9 element, which arrives at the second input of the element AND 5. Since the first input of the element 5 also contains a single the potential of the second ipsod of block 1, then through the time determined by the parameters of the discriminator 7

duration, at the output of one oscillator 6, an enabling signal appears, which through the OR element 2-1 enters the input of unit 1. Further reading of information frames with contact addresses between which the presence of false connections is checked takes place. Discriminator 7 duration

in this case, it carries out a time delay during which all transients in the device must be established. If there is a false connection between the two monitored contacts,

then a zero potential appears at the output of block 16 and, therefore, AND 5 is blocked by the zero signal from the EXCLUSIVE OR 9 element output, since its inputs contain

two zero signals. Entering the following information frames with the addresses of the next circuit to check for a false connection does not occur, and on the display unit 15, the addresses of the contacts between which there is a false connection are displayed. After its removal, the control for the existence of false links continues similarly. I
