Description

The utility model is intended for use as automation, mainly in automatic control systems for ventilation and air conditioning.

A well-known energy-saving ventilation and air conditioning system, including a driving supply fan, air conditioning, supply air temperature control sensor, indoor air control sensor (see the description of the invention to the patent of the Russian Federation RU No. 2244882 IPC F24F 5/00, F24F 11/00, dated 10/06/2003).

The known system reduces energy costs for heating the supply air, and also allows you to use the natural cold of the outdoor air to remove excess heat in the serviced premises during the transition periods of the year. However, it is cumbersome and may not be applicable for mobile base stations having, as a rule, insignificant dimensions.

A known system of automatic control and regulation for ventilation installations, including a driven supply fan, a sensor for monitoring the supply air temperature, a room air control sensor and a magnetic starter (contactor), (see the description of the invention to the patent of the Russian Federation RU No. 2098722 IPC F24F 11/08 from 07/20/94)

A disadvantage of the known system is that it maintains the required air temperature only due to ventilation, namely, air injection outside the room, for example, in the winter, and does not allow cooling the air in the room in the summer.

In general, all known automatic ventilation systems contain a set of blocks:

Controllers, speed controllers, mixing units, control modules, electric actuators for air valves (see http://www.ventilation.vinsit.ru/automatics/).

Each of the blocks, for example, controllers, contains many other blocks:

controllers for heating systems, controllers with analog output, controllers with three-position output, freely configurable controllers.

And the automation system is composed of such blocks and its control system is placed in the automation cabinet (see http://www.rfclimat.ru/htm/vent auto.htm).

Automation provides year-round operation of the ventilation system while maintaining the set temperature in winter operation. Shields perform the following functions:

- Management of inflow and exhaust fans;

- Maintenance of the set air temperature;

- Switching modes "Winter / Summer";

- Indication of the operation of fans inlet and exhaust;

- A multi-level anti-freeze protection system for a heater, including:

- control of a valve actuator with a return spring to close the air intake valve when the fan is turned off or when the power supply fails;

- control of the circulation pump on the strapping unit, providing a constant flow of water through the air heater;

- constant monitoring of the temperature of the return water in the air heater in all operating modes, including in the parking mode;

- constant monitoring of the air temperature at the outlet of the heater.

- Protection against overheating of fans;

- Protection against phase imbalance or loss of one phase;

- Protection during short circuit or overload;

- Indication and shutdown of system at pollution of the filter (option);

This shield is selected for the prototype. The disadvantage of such a shield (see http://www.rfclimat.ru/img/eguip/auto 11.jpg) is the complexity of its installation and connection, the presence of many wires and contacts. Those. all connections between the units are cabled. Each controller must be manually connected by contact with another controller or sensor, or brought to power supply. Also, the shield turns out to be rather bulky and heavy, and due to the presence of many wires and expensive.

The purpose of the utility model is to eliminate the disadvantages of the prototype.

Technical result: reduction of overall dimensions.

The claimed technical result as a whole is carried out by replacing the cable installation of the shield module with a printed one.

Utility Model Implementation

Automation module, consisting of a printed circuit board or a set of printed circuit boards, with elements of hinged and / or surface mounting and containing structural blocks that perform the following functions.

Inside the standard box of the electrical panel (see Figure 1) (21), there are boards: (20), (2), (5).

The power supply unit (1) provides the necessary characteristics of power supply circuits for the internal needs of the module and / or power supply circuits of external consumers. Block (1) is placed on the board (20) together with blocks (3, 4, 6, 7, 8, 9).

The boards (20) and (2) are interconnected by a loop (11), which is inserted into the connectors of the slots (9). Power is supplied to the switchboard via the terminal block (3), and communication with external equipment requiring control and diagnostics (by connecting to sensors) with the terminal block (4).

The block of protection of electrical circuits against overloads (6) consists of circuit breakers selected for the required power load, the power of which is supplied from the terminal block (3), then to the contactor (7) and the relay block (8). From the block (6), power is supplied to the fleas of the power supply (1). The feedback to the terminal block (3) from the contactor (7) is carried out on the basis that the supply voltage is supplied to the contactor (7), and the contactor, by the signal of the controller (2), supplies voltage to the other terminals of the terminal block (3) to which it is connected ventilation equipment. Signals from and to external equipment go through the terminal block (4) through electromagnetic relays (8), and then through the slot (9) to connect the communication loop between the boards (20) and (2), and the loop (11) to the board (2) - control controller block. Block (2) processes the signals of external and / or internal sensors and the control interface unit according to the program. It provides control signals to the display unit (5), the switching unit (20) of the power load and / or external devices.

The board (2) is a control controller unit, which processes the signals of external and / or internal sensors and the control interface unit according to the program, provides control signals to the display unit, power load switching unit and / or external devices.

On the board (2) there are electrical circuits leading the contacts of all the slots and connectors to the microprocessor (12), which is preferably removable so that it can be reprogrammed to a given power load. Slots (9) (at least one) are also located on the board (2) for communication with the board (20) and for connecting additional boards, such as (2), with a microprocessor control.

From the microprocessor (12), the contacts on the board (2) can be output to the SPI interface (10), which is used to diagnose the entire system through a computer and change operating parameters. Communication with the computer is through the SPI interface (10), into the connector of which a cable (17) is connected, leading through a special adapter (18) to a computer port (such as USB, COM, LPT) (19).

The board (2) is attached to the rear side of the board (5) of the display unit, which is installed on top of the board (20) so that the hole (16) in the board (5) lies on the switches of the unit (6) and they become externally accessible.

On the display board (5) there are light indicators (13), a display (14), control buttons (15), which are contact-connected to the board (2).

The power load switching unit is a contactor (7) interacting in conjunction with a relay (8). This unit enables / disables the power load circuits of external consumers and / or adjusts the power parameters for the power load circuits of external consumers.

The control interface block is a terminal block (4) through which control signals from the operator (user) and / or external devices are transmitted to the internal blocks of the module.

The display unit (5) provides audible and / or visual indication of the status of the operating modes of the module.

The block of protection of electrical circuits from overloads (6) monitors the state of external and / or internal consumers of electricity, gives signals about the parameters to exceed the permissible limits and / or disconnects consumers in dangerous conditions.

The reduction in weight and size characteristics is ensured by the transfer from cable to print.

The ability to quickly replace the block of protection of electrical circuits against overloads is realized by simply replacing one machine with another, since each machine is connected only by installing contacts at the input and output.

Replace the controllers inherent in a given load of the machine (as in the prototype) is not required.
