Abstract

FIELD: construction.

SUBSTANCE: forces are determined on code elements with the help of an appropriate sensor, signals of these sensor are converted into a digital form, and by the value of the signal with the help of the appropriate dependence, previously introduced into the computer memory, the mode of the necessary control action at a bolt is found, and the drive providing for a load at a bolt is changed to this mode found by the computer, afterwards in series with the help of the same sensor, threshold forces are recorded on each element, signals of this sensor are converted into the digital form, at the same time position of code elements is determined with the help of the position sensor and with the help of the appropriate dependence previously introduced into the computer memory, the mode is found with the necessary control action at the code elements, and the drive providing for action at code elements is changed to this mode found by the computer, and with the help of the appropriate dependence previously input into the computer memory, parameters of the code combination of the lock are found, and the lock is opened.

EFFECT: improved reliability, accuracy in detection of a code combination of a lock and elimination of subjective factors, also during its unlocking.

Description

The invention relates to the field of hardware and relates to methods for determining code combinations of key locks and unlocking them.

In the field of definition of code combinations of key locks and their unlocking, methods are known using devices controlled by the operator in manual mode.

The closest technical solution is the method of determining the combination of the lock and unlocking it, namely, that a constant load is applied to the bolt of the lock, the threshold forces are tactilely recorded on the code elements of the lock and its code parameters are visually determined using dimensional scales (patent for invention No. 2361050 , IPC EV 05/19, 2009, utility model patent No. 90104, IPC EV 05/19, 2009).

However, the known method is implemented with direct exposure to the operator and has the following disadvantages that are a consequence of this effect:

- low accuracy, which largely depends on such subjective factors as: operator qualification (obtaining and maintaining it is possible only with many years of constant training); physiological parameters of the operator (for example: tactile sensitivity, vision, memory); psychological stability of the operator in various situations and a number of other factors:

- significant time to achieve a positive result;

- lack of stability in obtaining a positive result;

- lack of repeatability in obtaining a positive result.

The objective of the claimed invention is to provide a method for increasing reliability, accuracy in determining the code combination of a lock and eliminating subjective factors, including when it is unlocked.

This problem is solved by the fact that the code combination of the lock is determined and unlocked not by the threshold forces tactically registered by the operator on the code elements of the lock, but by the fact that the forces on the code elements are determined using the corresponding sensor, the signals of this sensor are converted to digital form and by value signal using the appropriate dependence, previously entered into the computer’s memory, find the mode of the necessary regulatory action on the deadbolt and transfer the drive that provides the load on the deadbolt, this mode is found by the computer, after which threshold forces on each element are sequentially recorded. The signals from the force sensor are converted into digital form, while the positions of the code elements are determined using the position sensor and, using the appropriate dependence, previously entered into the computer's memory, they find the mode of the necessary regulatory action on the code elements and transfer the drive providing the effect on the code elements to this mode, found by the computer and using the appropriate dependency previously entered into the computer’s memory, determines the code combination of the lock and opens it.

The method described above for determining the code combination of the lock and its subsequent unlocking eliminates physiological factors when unlocking the lock (such as tactile sensitivity, memory, psychological stability), as well as increase repeatability and stability in obtaining a positive result.

The invention can be implemented using the device for unlocking the locks shown in the drawings.

Figure 1 presents a General view of a device for unlocking locks; figure 2 is a General view of the probe in section.

The device for unlocking locks comprises a housing 1 having the form of a stepped cylinder. A probe 2 protrudes from the housing 1 on one side, through which the pusher 3 passes, which is a round stepped rod with a flat protrusion in the form of a plate. On the opposite side there are electric motors 4, 5 and 6. To register the angular positions of the probe 2 and the pusher 3 in the housing 1 there are angular position sensors 7, 8 and 9. The probe 2 consists of two parts interconnected via a bearing 10, between these parts a force sensor 11 is installed to register threshold values, a spring 12 to provide a given clearance and a screw 13 to adjust the gap. Along the axis of the probe 2, a through hole is made through which the pusher 3 passes. The protruding part of the probe 2 from the housing 1 is a round rod with a flat protrusion at the end.

The claimed method is carried out by performing the following operations: mounting the device, entering data on the type of lock into the computer’s memory, resetting the device, automatically applying a load to the bolt of the lock, setting an automatic control mode for determining code combinations, sequential registration of threshold forces on each code element of the lock using the appropriate sensor according to the corresponding dependence, previously entered into the computer's memory, determining the code combination of the lock, open vanie castle.

In the process of obtaining data on the code combination of the lock, they find the mode of the necessary regulatory action on the deadbolt and transfer the drive that provides the load on the deadbolt to this mode, previously entered into the computer’s memory, and then the threshold forces on each code element are successively recorded using the force sensor, they are converted the sensor signals in digital form, while determining the position of the code elements using a position sensor and using the appropriate dependency previously entered into the computer’s memory, finding They set the mode of the necessary regulatory action on the code elements and transfer the device providing the effect on the code elements to this mode, found by the computer, and using the corresponding dependence entered into the computer memory in advance, determine the code combination of the lock and open it.

The information on the code combination obtained in the process of opening the lock and processed using the corresponding dependency entered into the computer's memory makes it possible to make a duplicate of the original key. The obtained information about the combination of the lock can be displayed on a screen or paper when printing data or using data transmission equipment can be transmitted via information and communication channels (for example, the Internet) or other types of communication to the center for the production of duplicate keys.
