Description

The invention relates to the field of technical means for monitoring and signaling service, sensitive and special objects and can be used to control the authorized and unauthorized passage of persons into the room.

A device for sealing a protected object [1] is known, which comprises a socket with an adhesive layer applied and an optical reading device for identifying the adhesive pattern.

A disadvantage of the known technical solution lies in the fact that the optical reading device is complex and does not provide documentation of the glue pattern during reception and security of the premises.

The closest known technical solution is a device for sealing an object [2], containing a platform fixed relative to the door of the room (object body), an end pusher (latch) and a casing. A sealing mass is applied to a fixed area, which is closed by a casing, which provides increased resistance to accidental (unintentional) opening of the protected premises.

The disadvantages of the prototype are:

- a small temperature range for the use of this device due to changes in the physico-chemical properties of the impression material under the influence of high and low temperatures, sunlight;

- low reliability, as after unauthorized access to the object, the use of this device does not impede the process of restoring the impression from the seal, for the implementation of which another seal or print substitute (coin, token) can be used;

- a high probability of uncontrolled access to the facility, for example, by a person making the closure and putting the facility under protection (if the facility is not equipped with an alarm);

- the great complexity of sealing the room, which leads to a decrease in the speed of transfer under the protection of the sealed room;

The aim of the invention is to expand the temperature range, increase reliability, reduce the likelihood of uncontrolled access by the person making the closure and putting the facility under protection, as well as reducing the time of transfer to the premises.

The essence of the invention lies in the fact that the proposed device for controlling access to a room, in addition to a platform, an end pusher and a casing, which is stationary relative to the room door, further comprises a door closer, a mechanical digit-to-numerical converter to an n-bit character code, a program installation unit and an n-bit presentation display a character code connected to n outputs of a mechanical digit-to-number converter into an n-bit character code, the control input of which is connected to the output of the program installation unit, the pusher is mounted on a fixed platform and kinematically connected to the counting input of the mechanical digit-to-number converter into an n-bit character code, which is located on the inside of the room door and is closed by a casing.

The novelty of the invention lies in the fact that the proposed device for access control to the premises contains a door closer, a mechanical digit-to-numerical converter to an n-bit character code, a program installation unit and an n-bit character code presentation display panel connected to n outputs of the mechanical digit-to-number converter into an n-bit character code, the control input of which is connected to the output of the program installation unit, the end pusher is mounted on a fixed platform and kinematically connected to the counting input mechanically of a digit-number to n-bit character code converter, which is located on the inner side of the room door and is closed by a casing, which reduces the time of transferring to the room security by presenting a fixed n-bit character code, which is automatically generated for visual control of the closed door state of the room at the time of the last closing of the room door.

Functional diagram of the proposed device is shown in the drawing, where it is indicated:

1 - door closer;

2 - the door of the secured premises;

3 - a casing;

4 - fixed area;

5 - end pusher;

6 - mechanical digit-to-number to n-bit character code converter;

7 - program installation block;

8 - scoreboard presenting n-bit character code.

In the initial position, using the closer 1, the door of the room 2 is closed. An end pusher 5 is mounted on a fixed platform 4, which is kinematically connected to the counting input of a mechanical digit-to-number converter into an n-bit character code 6, the control input of which is connected to the output of the program setting unit 7. Mechanical digit-to-number converter to an n-bit character code 6 is installed on the inner side of the door 2 of the room and is closed by a casing 3. The inputs of the presentation panel of the n-bit symbol code 8 are connected to the corresponding outputs of the mechanical digit-to-numerical converter 6 th character code.

The proposed device operates as follows.

When you open the door of the room 2, the end pusher 5 is displaced, which, in turn, through the kinematic connection, prepares a mechanical digit-to-number converter 6 into an n-bit character code. After that, the door closer 1 returns the door of the room 2 to its original position, the end pusher 5 also returns to its original position and, through kinematic communication, acts on the counting input of a mechanical digit-to-numerical converter into an n-bit character code 6, in accordance with the program received by the control input from the output of the installation block of program 7, a mechanical digit-to-number converter into an n-bit character code 6 converts the action into an n-bit character code and outputs it to the inputs of the presentation board 8 in the form of an n-bit symbol code, which is presented at the opening and handing over.

Thus, the symbol code at each closing of the door of the room is constantly changing, which prevents uncontrolled entry into the room, including authorized.

Depending on the design of the mechanical converter of the digit-number to n-bit character code 6, as well as the program coming from the output of the installation block of program 7, the numbers, letters of the Russian and Latin alphabets, and geometric figures (circle, triangle, asterisk, etc.), hieroglyphs and other symbols.

The industrial feasibility of the invention is justified by the fact that it uses the nodes and blocks known in the analogue and prototype for their intended purpose. The applicant created a valid device layout in 2006.

The positive effect of the application of the invention is that the temperature range of the application of the invention is expanded, the reliability increases, the probability of uncontrolled access by the person making the closure and putting the facility under protection is reduced to almost zero, the time of transferring to the premises is reduced by at least 80-90% by presenting for visual inspection of the closed state of the door of the room a fixed n-bit character code, which is automatically generated at the time of the last closing the door of the room.
