Abstract

The breach relates to computing and can be used in automatic systems for collecting and processing information. The purpose of the invention is to simplify the device and improve speed. The device contains filters, a switch, a counter, OR circuits, registers 2, a decoder. This goal is achieved by eliminating the mode of multiple recording of information about the status of sensors in the internal memory of the device and reducing the recording time of the state of the sensors due to the exclusion of the device stopping during the processing of the request for interruption of a computer. 2 yl

Description

The invention relates to computing and can be used. automatic systems for collecting and processing information.

The purpose of the invention is to simplify the device and increase the speed by eliminating the stopping of the device during the processing of requests in

Fig, 1 shows a functional diagram of the device; in fig. 2 - time diagram of his work

The device contains (FIG. 1) a group of filters 1, a group of registers 2, a switch 3, a counter 4, a decoder 5 a group of elements OR6. Positions denote the inputs and outputs of the device.

The device works in the following way.

In the initial state, the register is reset to zero by the input signal Reset 1.

When the i-ro sensor is triggered at an arbitrary point in time, the i-ro register 2 appears in the logic 1: Counter 4 generates a code that corresponds to the number of the interrogated register 2 and is equal to the number.

interrogated dvuhpipdnogo sensor. This code simultaneously emits to the address inputs of the cofgutator 3 and the inputs of the decoder 5, At the same time, it is on the control panel; output terminal 8 of the voice device; Гп: signal from the polled datask. At the same time, the reset input of the previous register 2 arrives at a signal from the output of the decoder 5 through the element I UB 6, which nullifies the previous register 2. This achieves an exception for the re-transmission of information 1-sh: about a single sensor trigger If the polled sensor did not work , then at information output 8 there is a logical About computer outputting a signal Polling to input 10, and ka: -; 1 Information output 8 displays the state of

next sensor. If the interrogated sensor worked and there is a logical 1 at information output 8, then the computer reads the code of the sensor number from address outputs 9 and returns the Polling signal to input 10 again.

The device's speed is ensured by reducing the polling time by eliminating {hile cycles to repeatedly recording information about the state of sensors in the device’s memory and reducing the time it takes to record the state of the sensors due to eliminating the device stopping by processing the request for computer interruption,
