The cabinet of input modules ШМВ-1 (hereinafter - ШМВ) (Fig. 5) is located in the switchboard room located in the control room and is intended for use in the automated well control system in the water intake system.

ШМВ is designed to perform the following tasks:

- interrogation of discrete and analog parameters from water level sensors in the tanks of the water intake system on the territory of the telephone network and their transmission to the operator's workstation via the RS-485 interface;

- transferring data received through the channel of communication equipment from the control cabinets of the ShKS-1 and ShKS-1-01 wells to the operator’s workstation via the RS-485 interface and transmitting commands to the ShKS-1 and ShKS-1-01 cabinets received from the operator’s workstation RS-485 interface, by means of a modem integrated in the ШМВ cabinet through the channel of communication equipment.

Electric power supply of ШМВ is carried out from 2 networks:

- from the main - single-phase AC network 100-264 V, frequency 47-63 Hz;

- from the backup - a source of constant voltage of 100-370 V. The power consumed by ШМВ from an alternating voltage network or a constant voltage source does not exceed 20 W.

Structurally, the ШМВ is made in the form of a body (cabinet) for wall-mounted (wall) mounting. On the door of the case there are LED lamps indicating the mains voltage - "~ 220 V" (yellow) and the presence of a supply voltage "= 24 V" (green). On the mounting panel inside the housing and on the side walls, circuit elements are installed. On the DIN rail in the upper right corner of the mounting panel, a circuit breaker QF1 is installed to turn on the power supply of the CMW from the AC mains. A QF2 circuit breaker is installed on the DIN rail on the left side wall of the cabinet to turn on the power supply of the CMB from a constant voltage source. A ground bus is installed on the bottom wall of the chassis.

The supply voltage ~ 220 V is connected to the circuit breaker QF1, then it goes to the terminal block ХТ1 for multiplication by 6 contacts. With ХТ1 voltage ~ 220 V is supplied:

- to the surge suppressor OPS1-0-2P (RU1);

- lamp "220 V" (HL 1) on the door;

- through a 10 Ohm thermistor with a negative TKS (RK1, limits the starting current of the power supply) - to the power supply DRA18-24A (A1);

- to the relay coil KM 1.

The backup power supply voltage = 110 V is connected to the QF2 circuit breaker, then it is supplied to the ХТ7 terminal block and through a 10 Ohm thermistor with a negative TKS (RK2, limits the starting current of the power supply) - to the DRAN30-24A power supply unit (A8). Also, the supply voltage = 110 V is supplied to the coil of the relay KM2.

Power supplies A1 (output power 18 W) and A8 (output power 30 W) power the circuit elements with voltage = 24 V from the main or backup power supply voltage of ШМВ. To decouple the outputs of the A1 and A8 power supplies, the + 24 V output circuits are supplied to the MDR (A9) diode isolation module, -24 V are combined on the ХТ3 terminal block. The terminal block ХТ3 is designed for multiplying the reserved voltage = 24 V by 8 terminals.

The galvanic isolation unit BGR4-24 / 24 (A2) is designed to power sensors with an output signal (4-20 mA) connected in a 2-wire circuit. The galvanic isolation unit BGR4-24 / 24 (A2) provides 4 channels of galvanically isolated output voltages = 24V-1 ... = 24V-4 with a load current of up to 40 mA. The channels are connected to the analog inputs AI1 ... AI4 of the measuring transducer A3 (figure 5).

The A3 measuring transducer (IP) has 8 universal (programmable for any standard types of sensors) analog inputs and 24 discrete inputs and is designed to measure analog and discrete parameters from sensors. The IP transmits the measured parameter values to the operator's automated workstation (operator's workstation) via the RS-485 No. 1 interface line. Input analog signals are connected to the IP through the terminal block XT4. Discrete input signals are connected to the IP through terminal blocks-adapters A4 and A5. A4 and A5 terminal blocks are connected to the X6 and X5 connectors of the measuring transducer by flat cables K1, K2. To multiply the terminals for connecting the common wire (DIGND) of dry contacts to 16 terminals, the DIGND circuit is output to the ХТ5 terminal block. FE is powered by voltage = 24 V.

AnCom STF / D5423i / 105 (A6) modem with an RS-485 output interface (RS-485 interface line No. 2) is designed for exchange with a controller well cabinet No. 2 (ШКС-1), with a controller well cabinet No. 3 (ШКС-1 -01) at the wells of water intake through high-frequency communication equipment (RF communication). The modem is connected to the RF communication equipment by a 4-wire telephone line (LINE connector). The RS-485 interface is connected via the A7 terminal block adapter, connected to the RS-485 connector of the modem by a short-circuit cable. The modem is powered by voltage = 24 V.

KM1, KM2 relays are designed to control the presence of the main (~ 220 V) and backup (= 110 V) power supply of ШМВ. Relay contacts are connected to discrete IP inputs on an A4 terminal block adapter. The output voltages of the A1 and A8 power supplies are also monitored. The voltages from the outputs of the blocks are connected to the discrete inputs of the measuring transducer A3 (IP) on the terminal block adapter A5.

During operation, it is possible to change the configuration (type of connected sensor and measuring range) of the analog inputs of the measuring transducer A3 (IP) installed in the cabinet of input modules ШМВ-1 (ШМВ). For example, when replacing the tank water level sensor with a sensor with an output signal of (4-20) mA, it will be necessary to change the measuring range of the analog input from (-5 mA ... + 5 mA) to (4-20) mA.

Changing the configuration of the IP is done from the operator's workstation via the RS-485 interface using the DASUtility service program.

If it is necessary to connect a sensor with an output (4-20) mA in a two-wire circuit, the sensor must be connected to the analog inputs AI1 ... AI4 on the terminal block ХТ4.

Distribution cabinet 1 of workshop 1 (hereinafter SR1 workshop 1) (Fig. 2) is located in the switchboard room located in the control room and serves to connect the AnCom STF / D5423i / 105 modem via a 4-wire telephone line to an automatic telephone exchange (hereinafter - ATS) and connections to the distribution cabinet 11 (hereinafter - SR11 KOS). ATS is located in the communication service building.,

The automatic water intake control system provides:

- automatic shutdown of the pumps when the water level in the tanks reaches 98%.

- automatic activation of the priority pump when the water level in the tanks decreases to 85%.

- automatic shutdown of pumps at a critically low water level in the well, in the range specified by the setpoint (adjustable).

The automatic water intake control system provides:

- automatic maintenance of air temperature in the vestibule and the working room of the container in the range specified by the settings (adjustable);

- safe operation in case of any failures and interference in the communication channel, and with a complete loss of communication, the current state of the equipment parameters is maintained.

The use of a high-voltage power line in a water intake control system is much more economical than channels with wired communication lines, since funds are not spent on the construction and operation of communication lines. A high-voltage power line is also more reliable than a radio channel, since when using it, the terrain is not an obstacle during operation, as when working communication lines using a radio channel.

Full automation of water intake management reduces labor costs, thereby increasing the efficiency of the system.

The automatic water intake control system provides increased noise immunity due to the use of digital-to-analog converters with digital signal processing in the RF communication equipment, as well as the presence of a high-frequency trap connected to a closed switchgear.

The developed system is universal and can be adapted for monitoring and control of any object, the power of which is carried out by means of a high-voltage line with a voltage of at least 6.3 kV. In addition, any section of a high-voltage power line of any class with a voltage of 6.3-750 kV passing in a passing direction can be used to connect the equipment.
