Cartoon explaining the operation of the pumping station.

Automatic sensors that monitor the values of their main process parameters.

When any parameter goes beyond the set limits, the pumping unit is switched off according to a specified program.

A backup unit is introduced instead.

The dispatcher records the stop.

Telemechanization based on automation ensures centralized monitoring and control of all pumping stations from the central control room.

The equipment of the control room consists of a receiving and transmitting device, processing units, reproduction and printing of information coming from the controlled points, control panels of the pumping stations.

Automatic recording of readings from telemetry and remote signaling sensors indicating the number of the polled controlled point and the time of data printing.

The values of pressure and flow settings are set, which correspond to the optimal operating mode of the given pumping station.

During the polling process, the system compares the values of the measured parameters with the specified optimal settings.

The data on discrepancies are signaled on the mnemonic device and recorded on a digital printing machine.

The system is switched to the emergency polling mode only for the controlled point at which deviations of parameters from the norm are recorded.

An emergency shutdown of the unit has occurred.

In this case, the system switches to an accelerated search and recording of the state of this point.

Since the system operates in the local control mode, the software launch of the backup unit is carried out at the pumping station.

Cartoon explaining the situation on the pipeline when the entire pumping station is disconnected.

The use of remote control in this situation allows you to switch the pipeline to a new mode in a matter of seconds by disconnecting one unit at each station.

In this case, a signal consisting of the code of the given point, the code of the controlled object and the command to turn off is sent to all controlled points in turn.

After signaling that the object has been selected correctly, a command is given to turn off the unit.

Remote control.

Consists of a remote assignment, setting, pressure in the automatic control system of the pumping station.

Cartoon explaining the signals passing during the remote control process.

From the district control point, constant remote control of the pressure along the pipeline route is carried out.
