Description

I

This invention relates to automation and computing.

A device for recording information is known, comprising an information generating unit, the output of which is connected to the registration unit, and the inputs to the distributor, the memory unit and the inequality unit associated with the memory unit by the polling unit connected to the distributor, the memory unit, a time sensor whose input is connected to the clock pulse sensor, and the output is to the time register.

In order to increase reliability, the proposed device contains a frequency divider, a decoder and elements "And, the first inputs of which are connected to a clock pulse sensor, the second inputs are connected via a decoder to the time register, inputs of a frequency divider connected to a clock sensor and elements" And, and output frequency divider is connected to the distributor.

The drawing shows a block diagram of the proposed device for recording information.

The device includes a time sensor 1, a time register 2, a clock pulse sensor 3, the elements 4, 5 and 6, a decoder 7, a frequency divider 8, a distributor 9, input buses 10, a polling unit I, a memory block

12, the inequality unit 13, the information generation unit 14, the registration unit 15.

The operation of the device is considered on the example of its use for recording technological information in the process of drilling oil and gas wells.

At the time of the beginning of drilling, time sensor 1 is turned on, the pulses of which are fed to the input of time register 2, counting

the drilling time of a given interval of penetration. In the process of deepening the well, the clock pulse sensor 3 (penetration sensor) outputs a pulse through a predetermined interval of penetration, which is fed to the first inputs

And 4, 5, and 6 elements, the second inputs of which receive pulses of the decoder 7, whose inputs are connected to the output of the time register 2. That element opens And the input of which simultaneously pulses the sensor of the clock pulses 3 and the decoder 7. Output signal A certain element "And enters the frequency divider 8 and sets a certain division factor. The pulses of the pulse sensor 3 are received at the input of frequency divider 8, where the corresponding coefficient is divided and entered at the input of the distributor 9. Thus, the sampling frequency of the parameters changes depending on the change

speed of mechanical drilling. In the future, the registration device is as follows. With the arrival of the pulse from the frequency divider 8, the distributor 9 connects one of the input buses 10 to the polling unit 11, where the parameter is measured. The contents of the polling unit AND and the memory unit 12 are compared in the inequality unit 13, which outputs a signal to the information generation unit 14. The printing of drying is indicated on the recording unit 15 only if the contents of the polling unit AND and the memory unit 12 are not equal at a given discreteness. Then a second parameter is polled, a comparison operation is repeated, and so on. After all input buses 10 have been polled, the information recording device returns to its original state and waits for the next clock pulse from frequency divider 8.
