Description

The invention relates to the field of technology of locking devices and can be used to control the opening and closing of office space.

A similar disposable electronic-mechanical sealing device is known, including a bolt for screwing into a critical part, a case in the form of a glass with end surfaces and a through hole for the bolt, an electronic mark with printed circuit boards installed inside the glass. It has a base and a radiolucent cover, and the base is made in the form of a flat frame, on the upper surface of which an electronic mark is installed, which is closed by a radiolucent cover. The disadvantage of this device is the disposability of its use.

The closest to the purpose is a sealing device containing a cylindrical body with two holes for mounting it on a protected surface and a recess for the sealing substance, in the middle part of which there is a through groove under the latch, having a rectangular working part located outside the case, and one end of which installed with the possibility of folding on the mounting axis, installed in the axial channel, deaf on one side, while the bottom of the recess for the sealing substance is flush with the top surface of the heck, characterized in that the upper and lower edges of the rectangular working part of the heck are cut symmetrically at an acute angle.

The disadvantages of this device are:

- hardening of the plastic material upon cooling to temperatures close to zero;

- sticking of plastic material on a personal seal, resulting in contamination of clothing;

- the closure of the room is increased by the time required for applying the print;

- the imprint on the door device for sealing may be inadvertently violated;

- it is possible to counterfeit the print by making a duplicate of a personal seal.

The aim of the invention (technical result) is to reduce time and simplify the process of closing the premises.

The main difference of the invention is that a reusable monoblock electronic device is used to seal the door to the room, which is installed on the keyhole on a hinge loop, consisting of a liquid crystal indicator, an electronic unit and a power source. The change of information on the indicator occurs only at the moment the device closes the keyhole. At the installation site of the device perpendicular to the door leaf, two electrically connected rods are mounted that perform the function of forming between the contacts of the electrical connection inside the device, signaling its installation. In the electronic unit, after the contacts are closed, a digital code is randomly generated with a simultaneous display on the liquid crystal display, and the readings of the indicator do not change until the device is removed. The values displayed on the indicator are reset when the keyhole is opened.

Control of the fact of unauthorized access to the secure premises is checked according to the indicated code, documented.

The control of the safety of the premises is carried out by reconciling the documented code with the displayed one.

The novelty of the invention lies in the fact that in the proposed device, such an operation as sealing by personal printing is completely eliminated, the possibility of falsification is prevented, and the time for taking measures to close and put the premises under protection is reduced.

The scope of the device is limited to doors located indoors.

A functional diagram of the implementation of the proposed reusable electronic device for sealing is shown in Fig. 1, where indicated:

1 - mounting kit (loop and pin contacts);

2 - electronic unit;

3 - code indicator;

4 - a constant power source.

A device that implements the proposed method of monitoring the opening-closing of office space, works as follows.

When the keyhole is closed by the housing of the device, the internal contacts are closed by the pin contacts 1, which is fixed by the electronic unit 2, which in turn illuminates a randomly generated code by means of indicator 3. The reset occurs when the keyhole is opened. The electronic unit can be implemented on the basis of the Arduino hardware platform, power supply 4 can be a battery integrated in the electronic unit Li-ion. The industrial feasibility of the invention is justified by the fact that it implements well-known nodes and mechanisms for its intended purpose.

The positive effect of the use of the invention is that it eliminates the possibility of using a copy of a personal seal, reduces the time it takes to take measures to put the premises under protection, there is no need to use plastic materials that harden at lower temperatures and stain clothes.
