Description

one

The invention relates to devices for microprogrammed control of mechanisms, mainly robotized technological complexes, and can be used in any industry that requires control of a complex of mechanisms according to a logic program.

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

The drawing shows the functional scheme of the device.

The device contains an address register, the first 2 and second 3 memory blocks, the comparison block 4 and the pulse shaper 5.

The device works as follows.

Before starting work, in blocks 2 and 3 of the memory, the address code identical to the current sensor status code is written for the first — the status code of the sensors in the next program execution step and for the second — the code by which the actuators must generate at the input of a device, a code identical to that recorded in memory block 2 at the same address.

Operation of the device at any step of program execution begins with writing the code of the current state of the sensors in the address register 1. Simultaneously with this, the code of the current state of the sensors is fed to the first inputs of the comparison unit 4. From the outputs of register 1, the code of the current state of the sensors goes to the address inputs of blocks 2 and 3 of memory. In this case, the subsequent state code read from the outputs of block 2 is fed to the second inputs of the compare block 4. Since in this case there is a mismatch of codes, there is a zero signal on the output of block 4 and shaper 5.

allowing the selection of information from blocks 2 and 3 of P. EMLTI and blocking installation inputs of register 1. Block 3 issues control commands to actuators, resulting in the sensors being set to the state corresponding to the code on the outputs of block 2. Thus coincidence of the codes at the inputs) 0 of the block 4 of the comparison, a single signal from the output of which the shaper 5 starts, producing a single pulse of a predetermined duration, during which the operation of 15 blocks 2 and 3 is blocked, and a new register is written to register 1 its state of the sensors, after which the device operates in a similar way.
