Description

The utility model relates to control and control systems based on alarm devices that respond to leaks in water supply systems and household appliances as a result of a violation of their tightness, and also allow detecting water leaks due to overflowing of the bathtub, sink and other containers used in everyday life. The system is designed to prevent flooding of the premises with water.

Known systems for preventing the flooding of rooms with water, which are characterized by the presence of two main functional units: sensors (detectors) for the presence of water and executive (locking) devices for automatically stopping water supply (blocking water supply) in emergency situations. The locking devices included in such systems can be controlled centrally using a specialized control unit that includes a controller. These functional units are connected to each other by communication channels, through which control commands for locking devices and test signals of detectors can be transmitted. Almost all known systems have been built according to such a scheme to prevent flooding of premises with water.

The communication channels used in the above systems can be wired and wireless (radio channels). The systems of the first type include, for example, the system according to the patent for the invention RU No. 2147145, G08B 25/00, the system according to the patent for the utility model RU No. 77073, G08B 21/20 and several others. The specified technical solution is implemented in a number of mass-produced products, of which the Aquastorozh system (www.water-com.ru) is the most famous. The disadvantages of such systems include the inconvenience associated with the need to lay wires in the room and protect them from accidental rupture and circuit. Additional issues related to

safety, arise in those systems for which power supply is used standard wiring with a voltage of 220 V.

To eliminate these shortcomings, radio-channel systems have been directed to prevent flooding of the premises with water, using autonomous low-voltage power sources. For systems of this type include, for example, a device for preventing the gulf of an apartment according to the patent for utility model RU No. 74505, G08B 21/20, which is the closest analogue of the proposed utility model.

This device contains several sensors for the presence of water installed by the user in places of the most likely leaks (leaks) of water, a control unit with an autonomous low-voltage power source, and actuators, for example, shut-off valves with electric drives. Water availability sensors are electronic devices made in a waterproof case with autonomous low-voltage power sources, made with the possibility of transmitting coded radio commands to the control unit. The electronic circuit of the sensor element of the presence of water (hereinafter, the sensor) in the normal state is in standby mode and is activated only when water enters its electrodes. In this case, the sensor generates a voltage pulse, which, using the coding unit, is converted into a modulating signal supplied to the input of the transceiver. In the transceiver, the specified signal is transferred to a high-frequency carrier and is transmitted to the air. Radiation is carried out at frequencies allowed for use by household appliances.

The sensor can be made with the possibility of self-testing, which is carried out according to a given program and / or upon requests received via a radio channel from the control unit.

The control unit is located in a separate housing and is installed by the user in a convenient place for him. It has its own low voltage power supply. When the sensor is triggered, the radio signal emitted by it

it is received by the transceiver of the control unit, decoded, subjected to an identification procedure, and if the radio signal is recognized as "own", a circuit is turned on that supplies voltage from the batteries to large capacitors connected to the electric drive of the locking device. With the normal operation of the locking device, the circuit of its electric drive breaks, which is monitored by the electronic circuit of the control unit, after which the voltage for charging the capacitor ceases to be supplied and the connecting wires are de-energized.

At certain intervals, the control unit receives test signals from water sensors. When the amplitude of the received radio signals is weakened (due to the discharge of batteries) or when the radio signal completely disappears, an alarm signal is issued to the sound signaling unit located in the control unit.

The locking device - a valve with an electric drive - is installed in the discharge pipe of the standpipe drain pipe (after a standard shut-off valve).

The locking device is connected to the control unit by means of electrical wiring of waterproof design.

Communication of water availability sensors with a control unit via a radio channel makes it possible to minimize the total length of wired communication lines, respectively, simplifying the installation of system functional units in the room and increasing its degree of safety.

The specified technical solution is implemented in a number of commercially available wireless devices for monitoring water leakage (leakage) and automatic shut-off of water supply sold on the commercial market, in particular, in AXICO AE001 and AT101 systems (www.axico.ru), VSTONIC MCT-550 (www .activsb.ru), EL-261 (www.flagmanspb.ru).

Along with the aforementioned advantages, these wireless (radio-channel) systems have one common fundamental disadvantage, which is as follows.

As you know, the greatest damage to the property of individuals and legal entities can be caused by water leaks (leaks) that occurred in the absence of the owners of the premises, for example, during their stay at work or departure to the country.

In accordance with the physical principles of the sensors for the presence of water described above, their operation occurs only when a layer of water of a certain thickness appears in the room. After the triggering of the indicated water availability sensors and, further, the locking device, the water supply to the water supply system of the rooms is blocked. However, it should be borne in mind that a certain amount of water has already entered the room. This water can spread over the floor and walls of the room, get on the furniture, penetrate through the cracks in the downstream apartments. At the same time, the longer this volume of water will be in the room - the more damage it can cause to the interior (for example, spoil wallpaper, furniture, floor coverings, ceilings living below neighbors).

The proposed technical solution is aimed at eliminating the indicated drawback of the closest analogue, that is, at minimizing the damage associated with possible water leaks (leaks) during periods when people are not in the room.

The subject of the proposed utility model is a system to prevent flooding of premises with water, containing several sensors for the presence of water installed by the user in places of the most likely leaks and water accumulations, a control unit associated with sensors for the presence of water through radio channels and one or more locking devices installed in the premises water supply pipelines and connected by their inputs and outputs respectively to the outputs and inputs of the notification of the control unit, while the task unit has been entered into the system mode containing radio-associated wearable identification unit and a reading unit, while the control unit is made with a forced input

blocking, which is connected to the output of the reading unit, which is the output of the mode setting unit.

The proposed system for preventing the flooding of rooms with water, contains (Fig. 1) water sensors 1 installed by the user in the places of the most probable leaks and water accumulations, a control unit 6 connected to water sensors 1 by a radio channel, and one or more locking devices 7, installed in the pipelines of the water supply of the premises and connected by their electrical inputs to the output of the control unit 6.

In addition, the system includes a mode setting unit 14 (FIG. 5), comprising a reading unit 16 connected to each other by a radio channel and a wearable identification unit 15.

In this case, the control unit 6 is made with an additional input of forced blocking, which is connected to the output of the read unit 16. The specified output is the output of the mode setting unit 14. The notification input of the control unit 6 is connected to the output of the locking device 7.

The water presence sensor 1 (Fig. 2) contains a sensor 2 connected in series with each other, on the surface of which there are electrodes 3 for detecting the presence of water, a coding unit 4 and a first transceiver 5 with an antenna.

The control unit 6 (Fig. 3) comprises an indication unit 13 and a second transceiver 8 connected to the antenna in series, a decoding unit 9 and an instruction generating unit 10. The first output of the command generation unit 10 is the output of the control unit 6, the second output is connected to the input of the display unit 13, and the third output is connected to the input of the second transceiver 8, while the second input of the command generation unit 10 is

With the exception of mode setting unit 14, all of the above functional units are commercially available and are used in radio channel water leakage control systems, for example, in the AquaControl 100 system (Installation and Operation Instructions, Special Systems and Technologies LLC, www.neptun-mcg .ru / technik / aquacontrol).

The principle of operation of unit 14 of the mode setting is similar to the operation of the unit of the same name used in automotive security systems and in contactless access control and access control systems (L.A. Stasenko, "Modern Radio Frequency Identification Technologies", "Security Systems", April-May 2004, p. 72-78). Wearable identification units 15 (transponders and key rings) serially produced by the applicant company are presented in the Accessories section of the Automotive Security Systems catalog, Altonika LLC, issue No. 9, 2006. Moreover, the connection of the reading unit 16 to the control unit 6 is similar to the connection reading unit with a central unit in the vehicle security system.

Thus, the possibility of practical implementation of the proposed utility model is not in doubt.

The system under consideration to prevent flooding of premises with water works as follows.

As noted above, sources of unauthorized appearance of water in a room can be like leaks in the water supply system and

household appliances (as a result of violation of their tightness), and water leakage in cases of overflow of unattended bathtubs, sinks and other water containers. Therefore, when installing the system in question (Fig. 1) in a room (in an apartment or in an office), the water sensors 1 included in the system are placed in places of the most probable leaks (leaks) and water accumulations.

The sensitive element of the water presence sensor 1 (FIG. 2) is a sensor 2, on the surface of which electrodes 3 are installed. Various installation options for the water presence sensor 1 can be implemented. For example, in the aforementioned AquaControl 100 system, the following two installation options for the water sensor 1 are recommended.

In the first version, it is recommended to install water sensors 1 in the floor (cut into a tile, coating) in places of the most likely accumulation of water during leaks. Sensors 1 of the presence of water are mounted by electrodes 3 up. A small protrusion of the sensor 1 of the presence of water (3-4 mm) eliminates false alarms.

If the insertion of the sensor 1 for the presence of water in the floor is impossible, it is recommended to put it on the floor with the electrodes down. The point protrusions on the housing of the water presence sensor 1 do not allow the electrodes 3 to touch the floor, which prevents the false presence of the water presence sensor 1.

When a water layer of a certain thickness appears, the electrodes 3 are shorted, and the sensor 2 generates a voltage pulse, which is encoded in coding unit 4. Coding can reduce the likelihood of false alarms due to external electromagnetic influences. From coding unit 4, the signal is supplied to the modulating input of the first transceiver 5 and is transmitted to the air.

On the radio channel, this signal enters the control unit 6 (figure 3), which is installed in a place convenient for maintenance and notification of users in the event of the appearance of water on the floor.

Structurally, the option of combining the control unit 6 in one housing with a locking device 7 installed in the pipeline is possible.

Both the water presence sensors 1 and the control unit 6 are equipped with autonomous power sources, with low voltage, which is important from the point of view of safe operation of the system.

The signal received at the antenna of the second transceiver 8 in the control unit 6 is supplied to the decoding unit 9. If the signal is decoded as "your own", then the unit 10 for generating commands is turned on, the output of which is connected to the electric drive 11 of the locking device 7 (Fig. 4). The actuator 7 is connected to a valve 12 configured to shut off the pipeline.

Embodiments of the locking device 7 may be different. For example, you can use the same option that is used in the closest analogue of this utility model. In this embodiment, the voltage from an autonomous low-voltage power supply installed, for example, in the unit 10 of the formation of commands is supplied to the capacitors of large capacity. After the said capacitors are fully charged, they are discharged to the winding of the electric drive 11 of the locking device 7, inside of which there is a magnetic core. Valve 12 is open in normal condition. The closure of the valve 12 inside the pipeline is due to the action of a spring. The spring in the normal state is compressed and locked by a mechanism controlled by an electromagnet. When applying voltage from the above-mentioned capacitors to the electromagnet winding, the core is retracted and the mechanism releases the spring - valve 12 is locked and blocks the water supply.

If the valve 12 has not closed within a predetermined time, from it - through the electric drive 11 - to the control unit 6 receives the signal of the command recharging the capacitors. This signal is supplied to the unit 10 of the formation of commands, after which the process of charging and discharging the capacitors is repeated

to the winding of the electric drive 11. This continues for a given number of attempts. If the valve 12 remains open, the display unit 13, at the command of the command generation unit 10, provides information about the malfunction of the locking device 7.

And in the event that the valve 12 normally works, the feedback of the locking device with the command generation unit 10 is broken, after which the voltage from the stand-alone power source stops charging the capacitors in the command generation unit 10.

Another important function of the unit 10 of the formation of teams is the periodic testing of sensors 1 for the presence of water. Test request commands from the unit 10 of the formation of commands are fed to the modulating input of the second transceiver 8 and are broadcast.

On the radio channel, these test request commands are received in the sensors 1 of the presence of water (figure 2). The test request commands received by the first transceiver 5 are sent to the coding unit 4, in which this sensor 1 for the presence of water is tested, the number of which corresponds to the address contained in the test request command. The response test signal generated in the coding unit 4 is supplied to the modulating input of the first transceiver 5 and is sent to them by radio channel to the control unit 6. In case of emergency, for example, when the autonomous power source of the sensor 1 for water is discharged, an alarm test signal is sent to the air.

This signal is received in the control unit 6 of the second transceiver 8 and after decoding in the decoding unit 9 is supplied to the command generation unit 10, which activates the display unit 13. The test alarm indication may be audible and / or illuminated. If the control unit 6 is in a place convenient for viewing, then the display unit 13 can be made in the form of an LED or liquid crystal panel (as, for example, is done in the closest analogue). The sound of a test alarm is also not excluded.

Consider, further, the features of the proposed utility model associated with the introduction into it of the block 14 of the job mode (figure 5).

The specified block 14 task mode is designed to force block the water supply in the absence of people in the controlled premises (for example, when they are at work or when the whole family leaves the city). It is this feature that makes it possible to eliminate the general drawback of the analogues mentioned above, including the closest analogue (utility model RU No. 74505, G08В 21/20). The fact is that, according to the principle of operation, all these systems in an emergency allow unauthorized entry into the room and spilling on the floor of a certain amount of water. This can cause damage (including to neighbors living on floors below), although less than in the absence of an analogue system.

In the general case, said mode setting unit 14 (FIG. 5) includes a wearable identification unit 15 and a read unit 16 connected to each other by radio.

The wearable identification unit 15 is located at the user. The reading unit 16 is installed stationary and can be performed, for example, in one housing with a control unit 6 and a locking device 7. The wearable identification unit 15 can be, for example, in the form of a transponder or a keyfob (with control buttons). In the first case, the reading range is from 1.5 to 2.5 m. In the second case, hundreds of meters, which allows you to control the locking device 7 from almost anywhere in the room.

When you press the button of the wearable identification unit 15, made in the form of a key fob, the latter emits an encoded radio signal in the frequency range allowed for use by household appliances. This signal is received by the reader 16, which identifies the user and, if correctly identified, generates a command to enable or disable the blockage of water supply to the premises.

Leaving the protected premises last, the user, by pressing the button of the wearable identification unit 15, made in the form of a key fob, turns on the blocking of the water supply through the pipeline. The first of the users who returned to the protected premises by pressing another button (or pressing the same button again) can release the indicated lock.

If a transponder is used as a wearable identification block 15, then the water supply is blocked when the user leaves the protected premises by bringing the transponder to the reading unit 15 at a predetermined distance. If you want to remove the specified lock, the user also brings the transponder to the reading unit 15.

Regardless of how the wearable identification unit 15 is constructed, the user is notified by the signals of the indication unit 13 about the entered blockage of the water supply through the pipeline (as well as the removal of this block).

Thus, the introduction of a regime setting into the closest analogue of the aforementioned block 14 allows to almost completely eliminate the possibility of unauthorized water entering the guarded premises - even in the absence of people in these guarded premises. If people are present inside the protected premises, then the system under consideration works in a normal mode, notifying users in case of leakage (leakage) of water.

By the principle of operation, such an algorithm is similar to the algorithm for setting rooms under protection and disarming.

The reading unit 16 can be made with the possibility of interaction with the security system (if available in the guarded premises). The details of this interaction are not disclosed in this application, since they go beyond the scope of this utility model and are the subject of another application (for an invention or utility model).

Thus, the task set in this utility model has been solved - a system has been created to minimize the damage associated with possible leakages (leaks) of water in the protected premises during periods when people are absent.
