Description

The invention relates to a technique for automatically remotely controlling an object and can be used, in particular, in automatic lines for various technological processes.

The purpose of the present invention is to increase the reliability of the device.

The drawing shows a diagram of the device installation object in the specified position.

The device for setting the object to this position contains a block of commands consisting of the setpoint adjuster 1 and the encoder 2, the first element OR 3, the storage register 4, the comparison unit 5, codes, the reversible counter 6, the second element AND 7, the first element AND 8, the second element OR 9, the executive unit 10, the pulse shapers 11 and 12, the third and fourth elements And 13, 14, the second trigger 15, the first trigger 16, the position sensor, made in the form of limit switches 17, - 17N, additional limit switch 18, registers 19 and 20.

The device works as follows.

When the power source is turned on, the first 16 trigger and memory register 4 are set to the zero state. In this case, a low potential occurs at the first output of the first 16 flip-flops, preventing signals from passing through the elements 7 and 8. At the second output of the first 16 flip-flops a high potential is formed, which forms the BACK command at the output of the second 9 element OR. Executive block 19 moves the object in the direction of the initial position. When the position is reached, an additional 18 limit switch is activated. The second 12 driver generates a pulse, which sets the reversing 6 counter to the zero state, and the first 16 trigger to one state. In this case, a BACK command is removed from the input of the executive unit 10, and a high level occurs at the inputs of the elements 7 and 8, permitting the passage of FORWARD and STOP commands. So

thus, the device is reset.

When one of the buttons of the command block 1 is pressed, for example, the buttons 1-2, the corresponding code is written into the storage register 4 and is fed to the input of the code comparison block 5. Since in the initial state in the reversible 6 counter zero is written, then at the output of the comparison block 5 codes a high potential is formed, which conducts through the element 7 and gives to the executive block 10 a FORWARD command

the first OR element - with the control input of the storage register, the code comparison unit, the first group of information inputs of which are connected to the corresponding outputs of the memory register, the object position sensor, made in the form of limit switches, and the execution unit, characterized in that, in order to increase reliability of the device

va, it contains four AND elements, the second OR element, two triggers, two impulses, additional

At the same time, this signal sets a limit switch and reversing the second 15 flip-flop into one state and permits the passage of pulses from the first 11 shaper through the third 13th element AND to the input of the direct count of the reversing 6 counter. When an object is run over each limit switch, a pulse is generated, which is counted by a reversing 6 counter. Thus, in the counter information is accumulated, 25 corresponding to the position of the object. When the codes coincide at the inputs of the code comparison unit 5 (in this case, when driving over the limit switch 17-2), a high potential is formed at its output, which passes through the AND 3 element and sends the STOP command to the executive 10 block.

If now to press the button 1-1 of the command block, a high potential is formed at the output of the code comparison block 5, which passes through the second 9 element OR and gives the command block 10 a BACK command. At the same time, this signal sets the second 15 trigger to the zero state. At the same time at the second entrance of the fourth
