Description

The utility model relates to means of ensuring fire safety, namely: to means of monitoring and displaying the parameters of the circuits of actuators, mainly powder fire extinguishing modules (MGS), and launching actuators upon a signal from any triggering devices or fire control devices in self-contained or automatic fire extinguishing installations.

Currently, in accordance with the requirements of NPB 88-01, the circuits of all actuators (modules, generators, etc.) in automatic fire extinguishing systems should be monitored “for open circuit”. As a rule, the protection of rooms by automatic fire extinguishing installations involves the installation of a large number of Ml 111 or other actuators, which are connected in parallel to the start-up circuit of the PUF, and all existing PUFs, when several actuators are connected in parallel to the start-up circuit, should be controlled to “open” their starting circuits can not.

Known fire control device PPU "Argus-PPU" manufactured by LLC "Argus-2AR" according to TU 11313393004001-98.

This device is designed to build fire extinguishing systems using various fire extinguishing means. The device receives control signals from the corresponding devices, monitors the failure of the fire extinguishing equipment’s start-up circuits (loops), fire extinguishing equipment starts in accordance with the incoming control signals, and also generates warning signals about the status of the start-up circuits.

The device includes a processor (logical unit), which provides coordination with wire lines and processing received signals and then, in accordance with a predetermined algorithm, generates programmed signals that are transmitted to the delay unit, which, in turn, generates signals for controlling the output relay taking into account the logical signal block. In this case, the check of the operability of the start circuits (“open circuit” test) is performed by the open circuit monitoring unit: when a circuit break is detected, the control unit, consisting of a relay and an open circuit indicator, generates a signal.

The reasons that impede the use of this device in full compliance with the requirements of NPB 88-01 include the lack of a control function for the starting circuit of each fire extinguishing agent in it.

A device for controlling the start-up circuit is known (RF patent for PM No. 45571, class IPC A62c 35/60, H02H 3/04, publ. 2005)

This utility model is intended for monitoring “breakdown” of start-up circuits of actuators - fire extinguishing modules when they are included in the start-up loop in parallel, for light indication of the state of the actuator start-up circuit, as well as for transmitting a status signal to the fire control device. This device is included in the electric start circuit, without violating the properties of the connection of actuators with the control panel, and cannot activate or block the passage of signals.

The aforementioned device includes an alternating current generator, a processor (logic unit), which provides the possibility of connecting a linear load (MPP) to the electric circuit, as well as a phase shifter and adder, which in turn is supplied with an electric signal from the phase shifter. The resulting signal from the adder is fed to a logarithmic amplifier, passes through a low-pass filter and an analog-to-digital converter, after which it enters a logic unit that performs a control function and transmits a signal about the state of the circuit to the fire control device.

The reasons that impede the use of the known device in accordance with the requirements of NPB 88-01 include the fact that the device is a passive element in the start loop, does not react in any way to the disconnection of the voltage supplying it, and in this position the device loses the function of indicating the status of the start circuit fire-fighting equipment.

The closest technical solution to the claimed on the basis of the essential features and the achieved technical result is the device according to the patent of the Russian Federation No. 45571.

Thus, at present, the urgent task is to ensure constant monitoring of the start-up circuit of each individual fire extinguishing means included in parallel in the start loop, as well as to ensure the launch of these means by a signal from the control panel. The proposed utility model is aimed at solving this problem.

When using the proposed device, the following technical result is achieved:

- provides constant control "on the open" of the start-up circuit of the linear load - any fire extinguishing means, for example, MPP;

- MPP is launched by an analog signal from the PPU;

- the linear load circuit parameters are displayed as part of any stationary fire extinguishing devices;

- there is an increase in the parameters of the safe test current in the start-up circuit of the device.

The proposed device does not cause and does not interfere with the activation of a linear load - for example, MPP, which should have the character of passive resistance from 0 to 50 Ohms and be low inductance.

The proposed device is consistent with the PUF, as well as with any other process control devices that control the common start circuit, and provides control of the start circuit of the linear load “open” with the issuance of light indication and signal transmission to the PUF.

The specified technical result is achieved in that the device is configured to connect it to the start-up circuit of the control device, and also to connect a linear load to the electric circuit, mainly in the form of a fire extinguishing module, includes an alternator and a processor, characterized in that it further comprises diode bridge, starting capacitor, current-limiting and test resistors, voltage regulator and starting key, interconnected to enable reobrazovaniya and supplying test current on start circuit to the processor, and also comprises a diode, a transistor and optocoupler relay start circuit connected to the AC generator for providing control and transmission to the signal processor.

To provide visual control, the processor may be configured to provide light indications, for example, in the form of an LED.

Information confirming the possibility of implementing a utility model to obtain the specified technical result is illustrated by the drawing.

Figure 1 shows a block diagram of the proposed device control the start circuit (when connected to the corresponding terminals of constant voltage from 12 to 24 V, the polarity is not observed),

Where:

1 - diode bridge;

2 - current limiting resistor;

3 - starting capacitor;

4 - voltage stabilizer;

5 - linear load (MPP);

6 - processor;

7 - test resistor;

8 - start circuit relay;

9 - indicator LED;

10 - diode;

11 - current generator;

12 - transistor optocoupler;

The proposed device is included in the start-up circuit of the PPU for each fire extinguishing medium (MPP, etc.) to control its start-up circuit for an “open”, as well as to start the MPP by an electric signal from the PPU.

The proposed device operates as follows:

1. In normal mode:

When you turn on a constant supply voltage of any polarity from 12 to 24 V to the corresponding terminals through a diode bridge (1) and a current-limiting resistor (2), charging of the starting capacitor (3) begins. Condenser charging time (3) 20-30 seconds. The voltage stabilizer (4) provides a stable voltage to the load circuit (5) and the processor (6). The test resistor (7) sets the test current through the load circuit (5), and the processor (6) analyzes the voltage drop across the load circuit (5). At the same time, the processor (6) closes the contacts of the relay (8) of the start circuit, restoring the start circuit. The normal operation of the device can be visually monitored by the light indicator in the form of an LED (9) (it starts to glow intermittently in green, and after 10-15 seconds it is constant).

2. When the start-up circuit of the linear load (5) is broken, the function of which is performed, for example, by MPP “Buran”:

If the start-up circuit of the linear load (5) is interrupted, the test current does not pass through the start-up circuit of the load (5) and the voltage value increases, while the processor (6) decides to open the contacts of the relay (8) of the start-up circuit, initiating an open-circuit of the start-up circuit, and the LED (9) lights up briefly in red.

In the absence of a supply voltage, the operation of the proposed device is turned off: the relay contacts (8) open, initiating an open circuit of the PPU start circuit (14), and the LED (9) turns off.

3. Launch of MPP-

when a start signal is applied to the linear load start circuit (5):

When the “START” signal is received from the control panel (14), a constant voltage from 8 to 26 V for a duration of more than 0.1 sec enters the load start circuit (5). The current passes through a diode (10) to a current generator (11), which gives a signal to a transistor optocoupler (12), which in turn transmits a signal to a processor (6). The processor (6) closes the contacts of the start key (13) and the start capacitor (2) is discharged to the start load circuit (5), the LED (9) starts to glow constantly in red.

All manufactured starter control devices are tested for proper operation.
