Description

The invention relates to a device for sealing and can be used to lock and simultaneously seal the doors of covered wagons, containers, tank hatches, helms of hopper cars and other rolling stock equipped with locking units.

An electronic sealing device is known, consisting of a body, a piece of rope permanently connected to it, a mechanism for its non-permanent fixation placed in the body cavity and interacting with the rope, the rope sensor and an electronic microcircuit connected to it, equipped with an information transfer element, are additionally located in the body cavity, with with the help of which an electromagnetic signal is generated, which is recorded by an external receiving device (utility model RU 51735, ЕВВ 39/02).

A disadvantage of the known seal is the inability to unambiguously determine the fact of opening the seal. Unfortunately, all currently used locking devices, including sealing ones, can be opened by intruders using specially made tools and techniques. Opening time depends on the complexity of the design of the device, the availability of a special tool and the degree of training of the attacker. Forensic experts often have the task of determining whether a given device was opened or not, and if it was opened, which traces could be left on the device mechanism with a special tool, and which were introduced during its manufacture, inspection, and operation. Often this task is impossible.

The technical result of the invention is the possibility of fixing the fact of opening or attempting to open the seal.

The indicated technical result is achieved in that the electronic sealing device consists of a body, a piece of rope permanently connected to it, a mechanism for its non-permanent fixation, located in the body cavity and interacting with the rope, the rope sensor and the electronic microcircuit connected to it are additionally placed in the body cavity information transfer element, with the help of which an electromagnetic signal is generated upon request, which is recorded by an external receiving device. The sensor is made registering the movement of the rope, while in the case from the side of its inlet, a sample is made that is closed on the outside by a sleeve, a profile washer is located in the sample with the possibility of rotation around its axis, having an opening whose profile repeats the profile of the cross section of the rope to form a signal for moving the rope when rotation of the washer, and the electromagnetic signal, which is recorded by an external receiving device, is formed taking into account the direction and magnitude of the movement of the rope.

The washer can contactlessly interact with the sensor, forming a signal of movement of the rope.

The washer can be kinematically connected with a sensor that converts the angle of rotation of the washer into the amount of movement of the rope, for which the outer surface of the profile washer can be made toothed, by means of which the driving mechanism of the sensor is rotated.

As a sensor recording the amount of rope movement, for example, a rotation angle (rotation) sensor can be used. To do this, in the well-known seal from the side of its inlet, a sample is made that is closed externally with a sleeve, and in the sample there is a profile washer with the possibility of rotation around its axis, the washer having an opening whose profile repeats the profile of the cross-section of the rope (utility model patent No. 49075 from 07/14/05). The rotation of the washer non-contact changes the state of the sensor, forming a signal of movement of the rope. The washer can also be kinematically, for example by means of a gear transmission, connected to a rotation sensor, the signal from which is recorded by an electronic microcircuit and converts the angle of rotation of the washer to the amount of rope movement.

The invention is illustrated by drawings, which depict on:

figure 1 - General view of the seal with the rotation sensor;

figure 2 is a block diagram of an electronic sealing device;

figure 3 a, b is an exemplary view of the signals recorded by an external receiving device.

The seal consists of a housing 1, a rope 2 and a permanent locking mechanism, which is made in the form of two balls 3 and 4 of different diameters, placed in an inclined hole 5, made at an angle to the longitudinal hole 6 of the housing 1. The balls are spring loaded relative to the plug 7 using a spring 8 The passive section of the rope is placed in the blind hole 9 of the housing and is permanently connected to the housing by plastic deformation in the zone of this hole. A sample 10 is made in the housing in the zone of the inlet, in which the washer 11 is rotatably rotated about its axis and is closed on the outside with a protective cover 12. The washer 11 has an internal hole 13, the profile of which repeats the cross-sectional profile of the rope 2. The protective cover 12 is installed in the sample tightened or sealed by plastic deformation of the housing elements. In the cavity 14 of the housing 1, closed by a cover 12, a sensor 15 and an electronic microcircuit 16 are located, equipped with an element for transmitting information 17 to an external transceiver 18. When the washer 11 is rotated, the sensor 15 changes its state non-contact, forming a rope movement signal 2. The device can be which the washer 11 is kinematically connected with the rotation sensor 15, which converts the angle of rotation of the washer in the amount of movement of the rope 2 by means of gearing.

The seal is hung on the locking unit of the car as follows.

The working segment of the rope 2 is passed through the eyes of the locking unit (not shown) and through the outer hole of the protective sleeve 11 is pulled through the longitudinal hole 6 of the housing 1 until a minimum loop is formed. The locking elements 3 and 4, compressing the spring 8, move inside the cavity 5 to the side of the plug 7, release the passage of the rope 2 through the longitudinal hole 6. When trying to force the rope to be removed from the seal body, the balls 3 and 4 under the influence of the spring and friction forces move towards the zone combining the longitudinal hole and the cavity of the case, jamming it inside the case. When the rope 2 passes through the longitudinal hole 6 of the housing 1, the profile washer 11, interacting with the strands of the rope 2, begins to rotate around its axis, and the larger the length of the rope passing through the profile washer, the greater the number of revolutions the washer will make around its axis, t. e. there is a direct dependence of the angle of rotation of the washer on the length of the rope stretched through it, since the pitch of the lay for a particular rope is a constant value. The angle of rotation of the profile washer is contactlessly recorded using a sensor 15, the signal from which is transmitted to a special electronic microcircuit 16 equipped with an information transfer element 17. Information from the sensor is accumulated in the microcircuit and stored there until a request is received from an external transceiver 18. After a request is received, the microcircuit 16 through the information transfer element 17 resets information about the number of revolutions of the washer 11 and the direction of its rotation. External transceiver 18 converts the received signals into information convenient for analysis by the operator, for example, when the rope is moved in the direction opposite to the closure of the seal, a warning signal appears that the seal was opened or an attempt was made to open it, and by what value the rope was removed from the housing.

Figure 3 presents an exemplary view of the signals recorded by an external receiving device, and Figure 3a shows a view of a signal characteristic of a seal that has not been opened, and Figure 3b shows a signal received from a seal that has been opened and then re-hung .

Using this invention, it is possible to precisely determine the moment of the manipulations performed with the seal.
