Description

The invention relates to locking mechanisms and the control of the position of parts of windows, doors, building structures and can be used to detect unauthorized opening of windows, doors, gates, locks, etc., for access control in the field of security alarm, security systems, security fire alarms, fire alarms, gate automation systems.

Known combination electromagnetic lock (RU 202686 C1, E05B 49/02, E05C 19/16, 2003). Its disadvantage is the impossibility of a hidden installation for controlling the relative position of the sashes and frames of plastic windows because of its cumbersomeness and the inability to control the remote using a radio signal, which, however, can be used as an integral part of the overall system for monitoring and fixing doors and windows.

A device is known for monitoring the state of a movable element (see, for example, P. Horowitz, W. Hill, “The Art of Circuit Engineering, vol. 2, M., Mir, 1993, page 218, figure 9.27). The disadvantage of this device is the need to supply power to the element, which requires additional wires and increases energy consumption.

A similar device is known containing a reed switch and a rod interacting with a controlled structural element (RU 2018962, 1991).

A device is known for controlling the position of one movable element located on another movable element (RU 2317590 C2, G08B 13/08, 2008) using a magnetic circuit (a sequential magnetic circuit is drawn up: a magnetically controlled magnetic circuit element is a magnetic field source). All components of this chain can be made in the form of cylinders, which allows them to be hidden in structural elements.

Its disadvantage is that in the known invention it is not indicated how the magnetically controlled element is connected to the security system, and specific parameters of the device that allow it to be implemented are not indicated.

The technical result of the invention is to increase the secrecy, efficiency and reliability of the device.

The technical result is achieved due to the fact that the combined electromagnetic lock for the control system for opening doors and windows, containing a power supply, electromagnets with two windings and a lock control module, which includes a microcontroller with a control input connected to an N-section switch, where N - the number of switch sections, the door sensor, the first and second controller-switch power with connected to them, respectively, the first and second ionistor batteries, and the first input microcontrol The era is connected to the output of the access control system, the second input of the microcontroller is connected to the door sensor, the first output of the microcontroller is connected to the first input of the first controller-power switch, the first, second and third outputs of which are connected respectively to the first, second and third terminals of the first electromagnet, the fourth output the first controller-power switch is connected to the positive terminal of the first ionistor battery, the negative terminal of the last, the fourth terminal of the first electromagnet and the fifth output of the first control the power switch is connected to a common wire, the second output of the microcontroller is connected to the second input of the second power switch controller, the first, second and third outputs of which are connected respectively to the first, second and third terminals of the second electromagnet, the fourth output of the second power switch controller is connected to the positive output of the second ionistor battery, the negative output of the latter, the fourth output of the second electromagnet and the fifth output of the second power supply controller-switch are connected to a common wire, you the strokes of the power supply are connected to the corresponding power inputs of the first and second power supply controller and microcontroller, the common output of the power supply is connected to a common wire, as well as the door speed sensor and an indication module, and the output of the door speed sensor is connected to the third input of the microcontroller, the third output of which connected to the input of the display module.

The result is achieved due to the fact that the control system for opening doors and windows contains a combination lock and an alarm system about the relative position of the housing and the movable element of the closing objects, containing a magnetic field source mounted on the housing magnetically controlled element and a power source and is characterized in that the system further comprises sensor - detector with LED indication of operation, made in the form of a wireless magnetocontact sensor containing a collapsible housing, electronic a circuit board on which two reed relays are installed, a power source, a microprocessor and a transceiver, so that when a permanent magnet is brought up to the reed relay, the latter closes the electric circuit through which electric current flows, and the microcontroller generates a signal that changes to built-in radio transmitter that transmits an alarm notification to the receiving control device with a used operating frequency of 868-868.2 MHz, while the magnet and the detector are installed at a distance of not more than 1 cm a friend from a friend.

In addition, an external reed switch can be connected, and the detector's overall dimensions are 85.2 × 28.2 × 10.5 mm, and the magnet 6.3 × 6.3 × 28 mm, and a 3-cell CR2032 lithium battery is used as a battery V.

In the particular case of execution by the body and the movable element are the frame and leaf of a wooden or plastic window, or the body and the movable element are the frame and leaf of a wooden or plastic door.

In the claimed invention, either the entire device (magnetic field source, reed switch + radio transmitter + power battery) can be hidden inside the structure (for example, the installation inside the window frame is shown in the drawing), or only the magnetic field source, alarms are transmitted via radio (wireless connections) .

The drawing shows the following positions:

1 - window sill,

2 - frame profile,

3 - rubber seal

4 - reinforcing profile (steel),

5 - sash profile,

6 - glazing bead,

7 - double-glazed window,

8 - detector

9 - magnet.

Due to its design, the wireless magnetocontact sensor (BMKD) can be placed inside the window frame of a metal-plastic window or door. The device can also be placed on a window frame or door. Until now, the wireless magnetocontact sensor was known as an overhead, i.e. placed only on the frame, not inside the frame.

An important difference of the claimed invention is that in the case when the BMKD is placed inside the frame, it is possible to obtain a hidden installation of a window magnet contact, and this significantly improves the anti-sabotage of the security system of the rooms in which the BKMD is used.

The principle of operation BMKD - consists of a body - a back and front cover, electronic board. The board has two reed relays, a lithium battery power source, a microprocessor and a transceiver. When a permanent magnet is brought to the reed relay, the latter closes the electric circuit through which electric current flows. The microcontroller monitors the amount of electric current and when this value changes, it generates a signal that is fed to the built-in radio transmitter. The transceiver transmits an alarm notification to the receiver-control device (PPC). BMKD batteries are enough for three years of operation of the sensor.

Work in statics.

BMKD transmits test radio signals to the control panel and receives confirmation from the control panel of the reception of the signal (receipt). In the case when the BMKD has not received a receipt, it re-repeats the test signals, gradually increasing the interval between them.

The limit values for the interval and the number of broadcast attempts are set by the sensor manufacturer.

When you open the window or door where the BMKD is installed, an alarm message is generated, which is transmitted by radio to the control panel. PPK, having received such a message from BMKD, transmits a receipt receipt to the sensor. If the window or door closes, BMKD transmits a signal to close the window or door by radio to the control panel. After 3 years of operation, the BMKD can transmit a message on the BMKD battery voltage drop via radio to the control panel.
