Description

The invention relates to automation and computing and can be used in automatic control systems. The purpose of the invention is to increase the device's carrying capacity. The drawing shows a structural diagram of the device. The device contains the first register 1, the encoder 2, the first key block 3 the second register 4, the third register 5, the second key block 6, the pulse generator 7, the divider 8, the pulse distributor 9, the trigger 10, the element 11, the information output 12, the first control The output output 13, the control input 14, the output of the pulse distributor 15, the information input 16, the address outputs 17 and 18, the second control output 19, the clock output 20. The device works the next time. A continuous sequence of pulses from the generator 7 enters a divider 8, from the output of which the input of the beginning of the interrogation cycle (operation) arrives at the input of the S-flip-flop 10, setting the trigger 10 to one. At that, the element 11 is opened and the pulses from the generator 7 pass to its output and then to the counting input of the pulse distributor 9. The leading unit at the output of the device 17 moves from the 1st to ITTf-1 output of the decoder, where fifi total number of outputs deshi () rator distributor. The positional output of the distributor 9 is connected to the information inputs of block 6. By means of pulses at the outputs of block 6, which are shifted in time relative to the input pulses of the generator by half a cycle, information is recorded sequentially in the register 5 cells from the information input of the device 16 the input of the device 16 is set to ecjjH not to take into account the transient process synchronously with the output pulses: and the generator. Register 5 from input 16 is filled with information from a peripheral device, which can be synchronized by the following device output signals: output 17, when the leading unit position uniquely determines 982 the peripheral device number and the cell number J where the information from this peripheral device will be entered ; a signal from output 18, when the number of the peripheral device is specified by a code from output 18, and the cell number of register 5 is specified by the position of the leading unit at output 17; signals from outputs 19 and 20. In this case, input of a serially parallel code 1-2-4-8 from autonomous devices that has an output to digital printing, for example, digital display devices Ф5147, Ф5095, etc., is easily organized. Output signal 19 It blocks reception of new information into the device, and using signals from output 20 (a pack of rectangular pulses), information is sampled and transmitted to information input 16 to fill register 5. After the polling cycle ends, a signal appears at the output of the distributor 15 at the end of the cycle. This is the last iTi output of the distributor decoder 9. This signal resets the trigger 10, which, in turn, resets the distributor 9 to zero and closes the element AND 11. Thereby the signal is output from output 19. At the same time, the output signal 15 j: the information from register 5 is rewritten into register 1. As can be seen, computers do not participate in such primary processing (accumulation) of information and thereby save machine time. Register 5 is ready to be filled with new information from peripheral devices (devices), and the information recorded in register 1 is sent to encoder 2, which converts information about the order, sign, type of input measured value into the required binary code and issues a ready signal to exit 13 in the computer. The code outputs of the encoder 2 are connected to the inputs of block 3, where those code outputs of register 1 are connected, the information from which does not require further identification, for example, the numerical value of the input value in binary code. The code of the input value does not pass through block 3 until a signal of input from a computer comes through input 14. Having received the ready signal, the computer introduces the device a signal of the input sign from the computer and the code of the input value.

is transmitted to register 4, from which enters the computer via output 12.

The device is organized cyclic offline mode, i.e. the frequency of polling cycles of the peripheral device (s) is set by the pulse sequence at the output of divider 8, and the frequency of the polling is set by the pulse sequence from generator 7 ...

This mode of operation from the point of view of maximum speed in obtaining results is most useful, since in this case register 1 stores information all the time, ready for transmission to a computer, with the exception of a short time for the signal of the end of cycle at output 15, to which new information

rewritten to register 1, i.e. on a command received at input 14 of the device, without waiting for the register 5 to be filled, it is possible to read the information stored in register 1.

Thus, the throughput of the device increases compared with the prototype, and therefore

10 increases the source nomenclature. information that can be connected to the device. The prototype device is designed to enter only one specific type of information — information that is manually typed on a remote control panel by manipulating controls such as buttons, toggle switches, and switches.
