Description

one

A device is known for monitoring and controlling the process of transporting fluid in pipelines, including pressure sensors mounted at opposite ends of the monitored pipeline sections.

The purpose of the invention is to ensure continuous monitoring of the state of pipelines, the termination of the pumping process and the overlapping of the emergency section.

To do this, at the ends of the pipeline section to be monitored are blocks with sensors interconnected by a communication channel and logical blocks mounted near the valves and connected by channels of communication with a logic device, each of which are connected to each other by logical blocks, one of which connected to the elements of sound and light alarm.

The information-logical device is based on a method of extracting information and transient processes occurring in a pipeline during an emergency rupture, then processing it in accordance with a logical algorithm, realizing it with logical blocks and issuing necessary commands and information signals.

The device consists of logical blocks.

interconnected electrical communication channels, with the help of which information is collected, processed and issued for visual observation and in the form of necessary commands for controlling electrified valves, localizing the emergency section of the pipeline.

FIG. 1 shows a block diagram of the device; in fig. 2 is a block diagram of a logic unit; in fig. 3 is a block diagram of a logic unit; in fig. 4 is a block diagram of a logic unit.

A device for monitoring and controlling the process of transporting fluid in pipelines 1 consists of logical blocks 2 and 3 located near pumping stations 4 and 5 and interconnected by a communication channel 6. Logic block 2 is connected to logical blocks 7 and 8 by link 9. Sensors

10 and AND are used to retrieve information when a pipeline is ruptured. Gate valves 12 and 13 are designed to localize the emergency pipeline section. Logic block 2 (see Fig. 2) consists of

the following main blocks: the receiving unit 14, the logical unit 15, the key 16, the generator 17 pulses, the counting unit 18, the program unit 19, the transmitting unit 20, the unit 21, the alarm, the siren 22,

unit 23 light alarm lamps 24

alarm, information presentation unit 25, pumping unit stopping unit 26, state of health monitoring unit 27, serviceability lights 28; electric clock 29, block 30 protection against false positives.

Logic unit 3 (see Fig. 3) contains the receiving unit 31 and the transmitting unit 32.

Logic block 8 (see FIG. 4) consists of a receiving unit 33 and a valve control unit 34.

Logic block 8 is similar to block 7.

Logic unit 2 operates as follows. When pipeline 1 is ruptured, sensor 10 responds to a pressure drop pulse and outputs efo to receiving unit 14, in which a useful signal is extracted, amplified, and the amount of leakage is determined. From the receiving unit 14, the signal enters the logic unit 15, whose purpose is to store information received from the receiving unit 14 and from communication channel 6 from the logical unit 3. When the second signal arrives from either end of pipeline 1, the logical unit 15 issues a command to turn on blocks of sound 21 and light 23 of the alarm, after which the signal lamp 24 lights up and the siren 22 turns on. At the same time, the electric clock 29 stops to record the time of the occurrence of the accident and a command is issued to the key 16, which turns on chenie n disable generator 17 pulses. From this generator, the pulses are fed to the counting unit 18, which is a four-bit binary-decimal counter, by means of which the time interval is measured and converted to the distance to the accident site. The information is output in the information representation block 25. From the counting block 18, information is output to the program block 19, in which the valve control algorithm 12 is laid out, and to the transmitting block 20, which issues a command via the communication channel 9 to the logic block 7 to localize the accident with the valves 12 and 13 with significant leaks after the command is issued from the receiving unit 14. At the same time, a command is issued to stop the pumping units (on

the drawings are not shown) in block 26 stop pump units. To monitor the health of the device, the electric clock 29 periodically issues a command to the health monitoring unit 27, where a single pulse is generated, which is fed to the receiving unit 14. If the logic unit 2 is healthy, then from the counting unit 18 a command is issued to the false positive protection unit 30, which It generates an automatic reset, i.e., preparing the logic unit 2 for operation, and simultaneously issues a signal to the health monitoring unit 27. When the logic unit 2 is operational, the correctability control lamp 28 is off and vice versa.

When the logic unit 3 is operating, the sensor 11 picks up the pressure reduction pulse and outputs it to the receiving unit 31, where the useful signal is extracted and amplified.

Next, the signal enters the transmitting unit 32, from which the signal enters the communication channel 6.

The operation of the logical unit 7. From the communication channel 9, the signal enters the receiving unit 33,

from which passes into the block 34 of the control valve 12.

Logic block 8 works similarly.
