FIG. 1 is a functional diagram of a combination lock; FIG. 2 is a functional diagram of a synchronizer; FIG. 3 is a functional diagram of a control unit; in fig. 4 is a functional block diagram of the comparison unit in FIG. 5 is a functional block diagram of a record block. The code lock (Fig. 1) contains a key mapping block 1, a synchronizer 2, a control block 3, a compare block 4, a memory block 5, a write block, an address counter 7, a decoder register 9, AND 10-12 elements , elements OR 13-14. Synchronizer 2 includes an OR 15 element, a generator 16, a counter 17, a trigger 18. The control unit 3 comprises a decoder 19, triggers 20-22, an OR 23 element, a counter 24, a decoder 25, shapers 26-27, OR elements 28-29, three ger 30, element NOT 31, elements I. 32-33, element OR 34, trigger 35. Comparison unit 4 consists of comparison element 36, element AND 37., counter 38, recording block b from the Enter button 39, code counter 40 , register 41, indicator 42, Start button 43, trigger 44, 45 clock counter. The device works as follows. When the key is inserted into the lock, the key and the lock are electrically connected by means of the key maker 1, and the lock elements are reset to the initial state. In this case, in block 3 of control (FIG. 3), trigger ger 35 triggers and generator OR 15 (FIG. 2) starts generator 16, and synchronizer 2 starts to operate. By the signal from the second output of synchronizer 2, the address 7 is zero from the block 5, the memory reads the value of the zero bit of the correspondence code, which through the open element AND 10 and the element OR 13 enters the key interface unit 1, and then into the key. According to the signal from the third output of the synchronizer 2, the state of the counter 7 of the address is changed by one and the first bit of the correspondence code is read from the memory block 5 into the key and so on. The signals from the third output of the synchronizer also go to the decoder 19 in the control unit 3, which, after issuing the matching code, will reset the trigger 20 to zero and set the trigger 21 to one. In this case, the lock is transferred to the reception mode of the code from the key. In this case, element 11 is hidden, and element 10 is closed. The key code is sequentially from the key 1 block with the key through the element 11 and the element I 12 enters the register 8 and the block 4 of the comparison, on the second inlet of which from the memory block 5 is the reference key code. Comparison element 36 compares the values of the indicated codes and the signal from the first one. The output of synchronizer 2 writes the result of the comparison into counter 38. The signal from the fourth output of synchronizer 2 writes the key code to register 8. After receiving the entire key code, the descrambler 19 in control block 3 resets the trigger 21 to zero and sets the trigger 22 to one. In this case, the driver 26 is triggered, and if the comparison is made, the signal from the counter 38 through the open element 33 goes to the decoder 9. The decoder 9 sends a control signal to one of the device outputs using this signal, depending on the received key code. If the comparison did not occur, the lock is transferred to the analysis mode of the received key code. At the same time, through the element AND 32, the non-comparison signal resets the counter 38 in the comparison unit 4, the element 11 and closes and the signal from the third output of the synchronizer 2 by the signal from the decoder 25 turns on the trigger 30 and opens the element 12. The received key code begins to circulate around the ring ; register 8 is an element AND 12 is an element OR 14 is a register 8 and is fed to block 4 of the comparison. At the same time, through the counter 7 of the address from the memory block 5, the subsequent cells are read, where the following key codes are stored, which also arrive at the block 4 of the comparison. At the end of reading each key-trigger 30, the signal from the decoder 25 is reset, thereby allowing, in the case of a comparison of codes, the passage of a signal through AND 33 from the comparison block. If there is no comparison, then the counter 24 will automatically zero and the cycle repeats. If a comparison has occurred, the comparison signal through the open element AND 33, the OR element 34 will turn on the trigger 35, which will block the operation of the synchronizer 2, and the operation of the device will stop. In case all the keys are read from memory block 5 and none match the received one, the signal from the decoder 19 through the OR element 34 also blocks the synchronizer operation, stopping the operation of the code lock. The recording of new codes in memory block 5 is as follows. The key matches with a lock, with this combination lock working in the manner described above, i.e. the key and the lock are identified. After that, using the Enter button 39, the first digit of the code is recorded in the counter 40 by an appropriate number of presses. This number is displayed on the 11 indicator 42 to check for correct input. After that, the Start button 43 is pressed. At this, trigger 44 is triggered and synchronizer 2 is started. The signal from the third output of synchronizer 2 triggers the first digit of the code to be copied to register 41, and then enters. into the memory block 5 and through the 1 key interface with the key into the key. After recording the per second digit, the 45 clock cycles reset trigger 44 to zero, synchronizer 2 is locked, and recording stops. Similarly, the remaining digits of the code are recorded sequentially. After writing the code, the key is undocked with the lock, and the combination lock is ready for operation. Thus, the code lock allows both keys to identify keys with different codes, which allows different access rights for each person to be delivered. This separation of powers provides a more reliable protection of monitored resources or objects, as it allows differentiating the capabilities of individuals depending on their belonging to different categories (administrators, users, service personnel, etc.). The code lock provided identifies keys with different codes. In addition, each official has an individual key, through which he gets access to the object. If an official is required to access several objects, then his code is written in the corresponding devices that control access to these objects. Thus, if the code recorded in the key is in the code lock, access to the protected object is granted. Consequently, the use of a code lock does not increase the keys for access of one person to different objects, which is convenient. in operation and does not lead to an increase in the amount of equipment, which determines the economic effect of using the invention.
