Project concept

This document has been developed for the purpose of performing a complex of automation and dispatching works:

- dispatching and automation of household drinking water supply;

- dispatching of drainage system automation;

- dispatching automation of the fecal septic tank;

. 1. Dispatching and automation of household drinking water supply.

1.1 To ensure the continuity of domestic drinking water supply with automatic switching to autonomous water supply from a well located on the site (when the city inlet pressure drops below 1.5 Bar); The electric power of the well pump is 7.5 kW, there is a power cabinet for controlling the well pump

Basic electrical circuits are present.

It is necessary to provide a pressure sensor in the system for signaling when the pressure in the water supply shaft decreases

1.2 Ensure the return to the main source of water supply during the restoration of urban pressure with the appropriate registration of an entry in the accident log;

The crash log can be on the computer and on the panel. The choice of equipment will depend on this. In order to organize this, you need to understand which valves are purchased, how the well pump control scheme is organized, To ensure control over the physical parameters of urban pressure, pressure in the autonomous water supply system on the BMS system;

The selection and procurement of the necessary sensors and materials is carried out by the contractor

1.4 To provide control of the current position of automatic valves on the BMS system;

Schematic diagrams of valve actuators will be provided

1.5 Stop the automatic supply of household drinking water to the building from the main (city water supply) and backup (borehole) sources by an external emergency signal "flooding". The selection and procurement of the necessary sensors and materials is carried out by the contractor

1.6 Functional scheme of water supply:

2. Dispatching of drainage system automation

2.1 Provide real-time monitoring of the drainage water level of the drainage well at the BMS system workstation;

To lay in the Masterskade project 3.11

2.2 To provide manual control of the drainage pump from the BMS system;

An electrical circuit of the electrical panel will be provided to finalize the automation scheme

2.3 Provide alarm of the critical water level in the drainage well.

The alarm must be provided by SMS notification

3. Dispatching automation of fecal pumps

3.1 Provide real-time monitoring of the water level in the well at the BMS system workstation;

To lay in the project of the Master Stage 3.11

3.2 To provide alarm of malfunction of pumps;

3.3 Provide manual control of pumps (working/standby) from the BMS system;

3.4 Provide a critical level alarm in the well.

4. Automatic gates.

Consider the possibility of signaling on the BMS system of signals: "there is no power supply;

Install the relay and send signals to the cliff, through the intermediate controller "the gate has not closed";

Install a relay + an additional limit switch and send signals to the cliff, through an intermediate controller, the current position of the automatic gate.

Install reed switches along the goal line. If the gates are above them, all are closed. Information will reach the controller and the scud
