Description

The invention relates to techniques for protecting objects from access by unauthorized persons, in particular to electronic control systems for electronic combination locks.

A device for controlling electronic locks is known (see AS No. 1176055 of 03/11/84, MKI E 05 B 49/00, "Device for controlling electronic locks", Ponomarev AK, publ. 30.08.85, Bull. No. 32 ), comprising a code dialing unit, a code setting unit, a logic unit, a lock drive control unit, at least one additional code setting unit, and a switch. The outputs of the code set block are connected to parallel inputs of the same name inputs of the code set block and additional code set blocks. The outputs of the installation unit and additional installation units of the code are connected to the inputs of the switch, the outputs of which are connected to the group of the first inputs of the logical unit, the first output connected to the input of the drive control unit, the first output of which is connected to the input of the switch, and the second output to the logical unit.

The disadvantages of the known electronic lock control device are its complexity due to the presence of a large number of connections between the blocks, low secrecy due to the possibility of opening any of the locks with the wrong code in case of switching the signal from the drive control output under the influence of interference, and small functionality due to the impossibility of access control to actuators in accordance with priority due to the fact that code combinations are not used different priorities.

Closest to the claimed invention by the set of essential features is a device for controlling electronic locks (see patent No. 2058468 from 10.22.90, MKI E 05 B 47/00, "Locking system", Edmin DM, publ. 04/20/96, Bull. No. 11), containing a lock with N converter channels (code converters), where N≥3, code signal switch, executive unit, N additional locks, N-1 code signal switches, code combination analyzer, distribution meter, M sensors code, where M≥N, valve, coding unit are followed code sensors. The outputs of N additional locks are connected via switches to the inputs of N converter channels, the outputs of which are connected to the executive unit through a code combination analyzer. The outputs of N converter channels are connected to the second inputs of the code combination analyzer through a distribution meter. The outputs of the code sensors through the valve are connected to the analyzer of code combinations, and the output of the counter-distributor through the encoder block of the sequence of sensors is connected to the second input of the valve.

The disadvantages of the known electronic lock control device are its complexity due to the presence of a large number of connections between the blocks, low secrecy due to the possibility of opening additional locks in any order, and small functionality due to the inability to differentiate access to actuators in accordance with priority, the inability to open locks with the lowest priority code of the highest priority and the inability to complete control (testing) Istemi without triggering any additional locks because the codewords are used with different priorities.

The problem solved by the present invention is the creation of an electronic lock control device having simplicity, increased secrecy and advanced functionality, namely: the ability to differentiate access to executive devices in accordance with priority, the ability to access executive devices with a lower priority, the highest priority code, and also the possibility of complete control (testing) of the device without triggering all additional actuators.

The technical result, which consists in simplifying, increasing privacy and expanding functionality, is achieved by the fact that the electronic lock control device contains N electronic locks, where N≥3, N code converters, the first and second code sensors with N outputs each, the third sensor a code having N-1 outputs and a first actuator, an information receiving unit, a code priority determining unit with N outputs, N code allocation devices, N first adders, N second adders, N-1 third adders and N-1 are introduced additional devices, wherein the input of the information receiving unit is the input of the electronic lock control device, and the first output is connected to the input of the code priority determining unit, each output of which is connected to the first input of the corresponding code allocation device, the second input of which is connected to the second output of the information receiving unit, and the output is with the first input of the corresponding first adder, the output of which is connected through the corresponding code converter to the first input of the corresponding second adder, the output of which is connected to the input of the corresponding lock, the output of which is connected to the input of the corresponding actuator, each output of the first code sensor is connected to the second input of the corresponding first adder, each output of the second code sensor is connected to the second input of the corresponding second adder, each output of the third code sensor is connected to the second input of the corresponding third adder, the output of which is connected to the input of the subsequent code converter, and the first input - with the output, respectively second adder, wherein each electronic lock consists of a reference code block and a comparison block, the first input of which is the input of the lock, the output of which is the output of the comparison block, the second input of which is connected to the output of the reference code block.

The specified set of features allows to simplify the circuit of the electronic lock control device by reducing the number of connections between the blocks, increase the secrecy of the device by eliminating the possibility of unlocking subsequent locks without unlocking the previous ones, and expanding its functionality due to the possibility of differentiating access to executive devices in accordance with priority, possibility access to actuators with the lowest priority code of the highest priority and in Moznosti of complete control (test) system without any additional switching actuators because the codewords are used with different priorities.

Eight information bits are divided into three priority bits and five code bits, thus the case is considered with N = 2 ³ = 8. The information receiving unit 1 (see FIG. 2) comprises a device 13 for determining the beginning of a code message, a generator 14, a shift register 15, a start-stop bit check unit 16, a delay element 17.

Block 2 determining the priority of the code can be made in the form of a decoder implemented on the chip KR1533ID7. Devices 3 ₁ , ..., 3 _N code allocation can be performed on the registers implemented on chips KR1533IR22. Adders 4 ₁ , ..., 4 _N , 7 ₁ , ..., 7 _N , 8 ₁ , ..., 8 _N-1 can be made on the elements “EXCLUSIVE OR”, implemented on the KR1533LP5 microcircuits. Converters 5 ₁ , ..., 5 _N code can be made in the form of switched jumpers (see USSR author's certificate No. 1807207, MKI E 05 B 47/00, published 07.04.93, Bull. No. 13). Sensors 6 ₁ , ..., 6 ₃ codes and block 12 of the reference code can be performed on non-volatile memory cells (see USSR Author's Certificate No. 845287, MKI N 03 K 19/16, published on July 2, 1979, Bull. No. 25). Block 11 comparison can be performed on the chip 1533SP1. Actuators 9 ₁ , ..., 9 _N are electromagnetic mechanisms controlled by a composite transistor.

The electronic lock control device (see Fig. 1) works as follows.

The code information is sequentially fed to the input of the information receiving unit 1. After the arrival of the code information, the device 13 for determining the beginning of the code message (FIG. 2) allows the clock signals from the generator 19 to the shift register 15 for recording. The code information with the delay determined by the delay element 17 is supplied to the shift register 15 for conversion from serial to parallel format using the clock signals of the generator 14. The delay of the element 17 must be selected so that the first clock signal of the generator 14 falls in the middle of the first bit interval of the code information , the synchronization frequency must be equal to the bit interval. After converting the last bit of the code message, the signal from the output of the device 13 for determining the beginning of the code message prohibits the operation of the generator 14 and is set to receive new code information.

The information converted to the parallel format is checked in the block 16 for checking start-stop bits (taking into account the fact that the start bit always has a logical unit value, stop bits - a logical zero). If the values of the start-stop bits of the input information do not coincide with the true values of the start-stop bits, the electronic lock control device returns to waiting for the receipt of the code information, in the opposite case, the signal from the output of the start-stop bit check unit 16 allows the operation of the code priority determination unit 2 .

Block 2 determining the priority of the code according to the priority of the incoming code connects one of the devices 3 ₁ , ..., 3 _N code allocation. Assume that came with the priority code, "two", the read device 3 ₂ dedicated code is supplied to the adder April ₂ and added to the code entered at block January ₆ b transmitter code. The result is converted in the converter 5 ₃ code and added to the code received from block b of the sensor 6 ₂ code in the adder 7 ₂ . The result of the addition goes to the lock 10 ₂ and is compared with the reference code of the lock 10 ₂ . If the codes do not match, the unlocking of the actuator 9 ₂ does not occur, otherwise the actuator 9 ₂ is unlocked. In addition, the result of the summation in the adder 7 ₂ goes to the adder 8 ₂ and is added to the code received from block b of the sensor 6 ₃ code. The result goes to the code converter 5 ₃ , is converted there and goes to the adder 7 ₃ , where it is added to the code received from the block from the sensor 6 _{2 of the} code. The result of the addition goes to the lock 10 ₃ . If the codes match, the actuator 9 _{3 is} unlocked. It should be noted that further unlocking of the actuators 9 ₃ , ..., 9 ₈ is possible only with the operation of the previous actuators, in this case, the actuator 9 ₂ .

Further, the unlocking process occurs in a similar way, that is, all the locks 10 ₄ , ..., 10 ₈ with the lowest priority are activated and the actuators 9 ₄ , ..., 9 _{8 are} unlocked. It should be noted that in the absence of errors or malfunctions in the electronic lock control device, the code with the highest priority unlocks all actuators of the lowest priority, that is, in our case, the code with priority two unlocks all actuators starting from the second (9 ₂ , ..., 9 ₈ ).

To check the operability of the device without triggering all actuators, there is an algorithm consisting in the following.

After the test code information arrives at block 2 for determining the priority of the code, information is received about the transition of the electronic lock control device to the test mode (special value of the priority bit). According to this signal, the code priority determining unit 2 connects the code allocation device 3 ₁ and blocks the operation of all locks 10 ₁ , ..., 10 ₇ , except the last 10 ₈ (the lock lock circuits are not shown in FIG. 1). Further, the operation of the device coincides with the operation of the device in the main mode, except that the unlocking of the actuators 9 ₁ , ..., 9 ₇ does not occur. The result of successful testing is the unlocking of the actuator 9 ₈ . Unlocking the actuator 9 ₈ allows us to conclude that all conversions and codes of all sensors 6 ₁ , 6 ₂ , 6 _{3 are} correct in the device, while the unlocking of the actuators with the highest priority does not occur.

A laboratory model of the electronic lock control device was manufactured, tests of which confirmed the feasibility and practical value of the claimed object.
