The device is designed to solve the following problem. The two-chamber shipping lock is in standby mode in its initial state, i.e. ships are not locked. As messages from vessels entering the upper or lower downstream are received randomly, the dispatcher of the central control panel for the two-chamber gateway (TsPUSh) generates queues of vessels in the upper and (or) lower downstream, analyzes the composition of the queues of ships and selects the appropriate strategy for locking ships (top up or down).

After analyzing the composition and lengths of the queues of ships located in the downstream chambers of the two-chamber lock, and choosing a locking strategy, the CPPC manager issues a command to prepare the lock chambers for receiving the ship. In the process of preparing the gateway chambers, it is possible to identify failures that must be eliminated, and only after their elimination is the training of the gateway chambers carried out and further locking. Let’s say the dispatcher has chosen a strategy for locking, starting first locking from top to bottom, and after passing all the vessels from the upper pool, the passage of ships from the lower pool begins, etc. Upon completion of the preparation of the two-chamber airlock chambers for receiving ships, the signal of the upper headlamp will light up, allowing vessels to enter the first chamber into the first chamber of the lock if the queue length of vessels N _{0 is} less than N ₁ , and into the first and second chambers if the length of the queue of ships N ₀ greater than N ₁ , after this the vessels enter the lock chamber, moor near the wall, close the upper gate of the lock chamber and the signal of the upper tail light comes on, prohibiting the entry of the next ship into the lock chamber. Next, the airlock chambers are emptied, the lower gates of the airlock chambers are opened, the ships are moored and the boats enter the lower pool.

The average time for carrying out these operations at the first camera is longer than at the second chamber of the gateway, therefore, the speed of the ship's passage is different. After the last vessels leave the lock chamber in the downstream, the dispatcher makes a decision to put the lock into standby mode or issues a command to lock the ships from the bottom up, and after the lock chamber is prepared for the reception of the ships, the signal of the downstream traffic light will illuminate, allowing the vessels to enter the downstream queue to appropriate lock chamber depending on the length of the ship queue. Vessels from the downstream queue enter the airlock chambers, moor near the wall, close the lower gates of the airlock chambers, and the downstream traffic signal lights up, prohibiting the entry of new vessels into the airlock chambers. Next, the lock chambers are filled with water, the upper gates of the lock chambers are opened, the ships are moored and the ships leave the lock chambers to the upper pool. After the exit of the last vessels from the chambers to the upper pool of the gateway is completed, the dispatcher makes a decision and issues a command to lock the vessel from top to bottom or puts the gateway into standby mode. The process is then repeated. Other situations are possible, some of which are considered when describing the operation of the device. The above-mentioned processes of functioning of two-chamber shipping locks during the passage of vessels can begin at random times and leak random time intervals distributed according to various laws.

The task of the device is as follows. Using the device, we simulate the functioning processes of a two-chamber shipping lock with different lock strategies and for different laws of distribution of random time intervals of their flow, taking into account the dynamics and specifics of their application, as well as the occurrence of failures in the preparation of the lock and their elimination, counting the statistical characteristics of these processes according to the counters connected to various elements of the device, it is possible to evaluate various probabilistic-temporal statistical indicators of processes unktsionirovaniya as absolutely reliable and unreliable two-chamber navigation lock, as well as to investigate the effect on them of basic operational and technical characteristics of the two-chamber navigation lock and taking into account the dynamics of their specific application requirements to justify them and the way they provide.

The device operates as follows. In the initial state, trigger 2 of model 1 is set to a state where the enable voltage is present at the first input of element And 3, and indication element 14 shows the gateway is in standby mode, triggers 18.19 of model 1 are set to the position at which the first input of elements And 8, And 9 there is no enable voltage, and at the first input of the elements And 10, And 11 of model 1 there is enable voltage, at the second input of the And 36 element and the first input of the And element 37 of models 34 and 34a there is inhibit voltage. The trigger 33 of models 25 and 25a is set to the position where the And 26 element is open at the inverse input, the And 27, And 28 elements are closed at the first input. Flip-flop 71 of models 55 and 55a is set to a position where a direct voltage is present at the direct output, which is displayed on the display element of 69 models 55 and 55a (prohibiting traffic signals). Flip-flop 56 models 52 and 52a, flip-flop 65 models 53 and 53a, flip-flop 66 models 54 and 54a are set to the position at which the first inputs of the elements And 57, And 62, And 67, as well as the third and fourth inputs of the element And 57 specified models there is a permissive voltage. The trigger 50 of model 45 is set to the position where, on the second input, the element And 35 of models 34 and 34a, the element And 61 of models 53 and 53a are open, and at the inverse input, the element And 47 of model 45 is closed. Generators 6, 7 of model 1, generator 21 of models 20 and 20a, generators 64, 68 of models 44, 44a are not running, the reversible pulse counters of 22 models 20 and 20a are reset. In the blocks 58 for preparing models 52 and 52a of models 44 and 44a, the generators 74, 75 and 78 are not started, at the second inputs of the elements And 76 and I 77 there is a resolution voltage from a single output of the trigger 80.

The device can operate in modes that implement the following lock strategies: selection of lock strategies depending on the queue of vessels in the upper and lower pools; the passage of vessels through the two-chamber lock from top to bottom, i.e. lock ships from the upper downstream with one (first) camera, followed by turning on the other (second) camera when the vessels in the upstream reach the queue N ₀ ≥N ₁ and turn off the second lock chamber when the vessels in the queue are reduced to N ₀ ≥N ₁ -1; passage of vessels through the lock from the bottom up, i.e. lock of vessels from the downstream to the upper one (first) camera with the subsequent inclusion of another (second) camera when reaching the queue of vessels in the downstream N ₀ ≥N ₁ and turning off the second lock chamber when the vessels in the queue are reduced to N ₀ ≥N ₁ - one; two-way traffic through the gateway, i.e. sequential locking of all vessels from the upper pool from top to bottom (or bottom-up from the lower pool) with the subsequent transition to locking from bottom to top (or top to bottom). The average time T ₁ (i.e., the lock speed V ₁ ) is spent on locking the ship with the first camera, and the average time T ₂ (i.e., lock speed V ₂ ) is spent on locking the ship with the second camera, and the condition T ₁ > T ₂ (V ₂ <V ₁ ). After turning on the device, all its triggers are reset. At the output of trigger 2, connected to the first input of the And 3 element, there is a permissive voltage, at the individual outputs of the triggers 18,19 connected to the first inputs of the And 8, And 9 elements of model 1, respectively, to the second input of the And 36 element and the first input of the And element 37 models 34, 34a, respectively, there are no permissive voltages; at the zero outputs of triggers 18.19, connected to the first inputs of elements 10, 11, there is a permissive voltage. This state of the device corresponds to the standby mode of the gateway. Further, in all modes, the operation of the device is supported automatically after turning on separately or simultaneously the generators of 21 models 20, 20a.

The operation of the device when locking ships from the upper pool to the lower one is as follows. The simulation begins by turning on the generator 21 of the model 20 (the generator 21 of the model 20a is turned off), which generates sequences of random pulses that adequately reflect the laws of receipt of applications for locks from the upper waters. The pulses from the output of the generator 21 are fed to the summing input of the reverse pulse counter 22, the bit outputs of which are connected to the corresponding inputs of the decoder 23, the number of which is n, and the number N ₂ = 2 ⁿ , which are connected to the corresponding inputs of the OR element 24. Using the combination of elements: generator 21, reverse counter 22, decoder 23 and element OR 24 of model 20 simulate the process of organizing a queue of vessels in the upstream length N2. If there is at least one (one vessel) at the first output of the reversible pulse counter 22 of model 20, a high potential appears, which through the first input-first output of the decoder 23 enters through the element OR 24 of model 20 to the second input of the element And 4 of model 1, opening it, and also from the output of the OR element 24, through the first input of the OR element 16, it enters the second input of the open And 3 element and then goes to the single input of trigger 2, translating it into a position in which a low potential appears on its direct output, And 3 closes a first entry, indicating element 14 detects the end of finding a standby gateway.

The high potential from the output of the And 3 element simultaneously arrives at the first input of the And 4 And 5 elements. Since the And 5 element is closed on the second input, because the output of the OR element 24 of model 20a is zero potential, there will be no signal at the output of the And 5 element and through the And 10 element, the generator 7 will not be started. Since the And 4 element at the second input is open, the signal (high potential) received from the And 3 element output to the first input of the And 4 open element passes through the second input of the And 11 open element to the start input of the generator 6. After some random time at the output generator 6 a single pulse appears, simulating the moment of decision making and issuing permission to lock ships from top to down by the dispatcher of the central gateway control panel. The pulse from the output of the generator 6 is supplied to the installation input in the “0” trigger 18 and puts it in a position where the element And 8 of model 1 opens at the first input, the element And 36 at the second input and the element And 37 of model 34 at the first input, the stop input of the generator 7, to the first input of the element And 42 of the model 41, as well as to the second input of the element And 29 of the model 25 open at the first input. Depending on the length of the queue of vessels in the upper pool, the device operates as follows.

If the turn of the upper pool of ships is N ₀ <N, then the pulse from the output of the And 29 element of model 25 will pass through the delay element 30 opened by trigger 33 at the inverse input of And 26, the second input of OR 32 of Model 25 and will go to the first input of OR 59 models 52 and further enters through the second input of the And 57 element open at the first, third and fourth inputs to the installation input in trigger 1 of "56", puts it into a state in which the And 57 element closes at the first input, and also enters the 58i input block 58 training model 52, passing through the element And And 73 drives the generator 74, simulating the beginning of the preparation of the first lock chamber vessels to pass downwards.

The operation of the training unit 58 in the event of a failure and its elimination is reduced to the following. Generator 74 of block 58 generates a pulse of random duration, adequate to the preparation time of the first (second) lock chamber for the passage of ships from top to bottom, which, when entering the differentiating chain 79 (differentiation of the leading edge of the pulse), starts the generator 78 of a random sequence of pulses simulating the failures of the gateway that comes through an open element And 77 to the first input of the OR element 84 and then to the stop input of the generator 74. And also to the start input of the generator 75, forming a pulse of random duration, adequately th time failure is recovered (recovery), which is acting on the differentiating circuit 80 (differentiation pulse leading edge) needs to trigger 83 in a condition in which the AND 76 and AND 77 are closed. At the end of the pulse at the output of the generator 75, received at the differentiating element 82, which carries out the differentiation of the trailing edge and its subsequent inversion, and a positive pulse from its output goes to the input of the installation in “1” of the trigger 83, which opens the elements I76 and I 77, and also arrives at the second input of the OR element 73 and starts the generator 74, which corresponds to the beginning of the repeated preparation of the gateway after eliminating the failure.

If during the preparation there were no failures, i.e. During the duration of the pulse generated by the generator 74, there was no pulse at the output of the generator 78, then the pulse from the output of the generator 74 entered the input of the differentiating element 81, which differentiates the trailing edge and then inverts it, and a positive pulse from its output goes to the first input element I76, at the output (output 58 of block 58) of which a single pulse appears, which through the delay element 40 of model 34 is fed to the installation input in “1” of trigger 56 of model 52 and sets it to the original state melting, opening the AND element 57 at the first input, and also goes to the first input of the And 35 model 34 element open at the second input and then through the OR element 38, the first input of the And 36 element open at the second input and the OR element 39 passes to the subtracting input of the reverse counter 22 pulses of model 20, thereby simulating the exit of the vessel from the queue of the upper pool into the first chamber of the gateway. The pulse from the output 58 ₃ of the preparation block 58 (the output of the And element 76 of the block 58) of the model 52 also arrives at the first input of the And element 46 of the model 45, and through the delay element 60 of the model 53 to the first input of the open element And 61 of the model 53 and then through the OR element 63 to the input of the installation in “1” of the trigger 71 of the model 55, which translates it into a position at which a high potential appears on its inverse output and the indication element 70 simulates an enable signal for the vessel to enter from the upstream into the first chamber.

The pulse from the output of the OR element 63 also enters through the open element And 62 to the installation input in the "0" trigger 65 model 53, puts it in a state in which the element And 62 and the third input element And 57 are closed at the first input. After some random time after the start of the generator 64 of model 53, proportional to the time the vessel entered the first lock chamber, moored the ship and closed the upper gates of the first lock chamber, an impulse appears at the output of the generator 64 of model 53, which will arrive at the input of the trigger to “0” model 55 and translates it into a position in which the display of the display elements 69 and 70 will change, corresponding to the prohibiting signal of the traffic light for the vessel to enter the first lock chamber.

The pulse from the output of the generator 64 of the model 53 also arrives at the input of the installation in “1” of the trigger 65 of the model 53, transferring it to its original state, thereby opening the And 57 element of the model 52 at the third input, and opens the And 62 element of the model 53 at the first input. The pulse from the output of the generator 64 also goes to the second input of the open element And 67 of the model 54 and starts the generator 68 of the model 54, at the same time goes to the input of the installation in the "0" trigger 66, translating it into a position in which the element And 67 are closed at the first input and on the fourth entrance, the element And 57. Through some For a random time, adequate to the time of emptying the first chamber of the lock, opening the lower gate, starting the vessel and entering the downstream, the generator 68 gives a single pulse, which, entering the input of the unit in “1” of the trigger 66, transfers it to its initial state and the element And 67 of model 54 opens at the first input, element 57 of model 52 opens at the fourth input, also this pulse enters through the first input of element OR 17 of model 1 to the second inputs of elements AND 8, AND 9 of model 1.

Since the And 9 element is closed at the first input by the inhibitory voltage from the trigger 19, and the And 8 element is open by the enable voltage from the output of the trigger 18, the pulse from the output of the OR element 17 will pass through the And 8 elements, the first input of the OR element 15 to the installation input to " 0 "trigger 2 of model 1 and translates it into a state in which there is a high potential at the first input of the element And 3 model 1, ie The device has entered standby mode. Further, the device operates automatically when passing ships from top to bottom, i.e. the cycle repeats.

If the queue of the upper pool of ships N ₀ ≥N ₁ , then the second chamber is included in the lock process and the device operates as follows. The pulse from the output of the generator 68 of model 54, simulating the output of the vessel from the first lock chamber to the downstream, passes the element OR 17 of model 1 and goes to the second input of the open element And 8 of model 1, then through the elements OR 15 to the input of the trigger 2, transfers it to the position at which the AND 3 element opens, the high potential (signal) from the output of the OR element 24 of model 20, passing through the OR 16, AND 3, AND 4, AND 11 elements of model 1, is input to the start of the generator 6 at the output of which, after a random time, an impulse appears. This pulse enters through the second input of the open element And 29 of the model 25 to the inputs of the delay elements 30, 31.

Since there is N ₀ ≥N ₁ in the upstream, the high potential from the Ni-th output of the decoder 23 of model 20 will transfer the trigger 33 of model 25 to the state in which the And 26 element closes at the inverse input, and the And 27, And 28 elements open at first entrances. Then the pulse from the output of the delay element 31 enters the second input of the open element AND 27 of model 25 and passes to the first input of the OR element 59 of model 52a, i.e. the second gateway camera is turned on and models 52a, 53a, 54a are then operated similarly to the models 52, 53, 54 of the first gateway camera described above. At the same time, the pulse from the output of the AND element 29 of model 25 enters through the delay element 30 to the second input of the open And 28 element and through the OR 32 element to the first input of the OR element 59 of model 52, i.e. the first camera continues to function and the device operates as described above. Thus, the inclusion of the second chamber of the two-chamber gateway and the joint operation of two cameras of the gateway simultaneously when locking ships from top to bottom is realized.

When reducing the queue of ships N ₀ to N ₁ -1 there is a reverse switching of the gateway cameras, i.e. after the ship’s lock No. ₁ , the operation of the second lock chamber ceases, the first lock continues to lock. This is achieved by the fact that the high potential that appears on the (N ₁ -1) - m output of the decoder 23 of the model 20 and arrives at the input of the installation in the "0" trigger 33 of the model 25, throws it into a state in which the And 26 element opens and closes on the first input, elements I 27 and I 28 of model 25. Further, the device operates similarly to that described.

When locking from the queue of the upper pool of the last vessel, the device operates as follows. The pulse from the output 58 _{3 of the} block 58 of the preparation of the model 52 through the delay element 40 of the model 34, elements AND 35, OR 38, AND 36, OR 39 of the model 34 is fed to the subtracting input of the reverse counter 22 of the model 20, resulting in the output of the element OR 24 of the model 20 there will be zero potential and the element And 12 of model 1 will open at the inverse input. The same pulse from the output 58 _{3 of} block 58 of preparation 52, having passed, as described above, the path along the elements of models 53, 54, 1, will go through element OR 15 to the installation input in the “0” trigger 2 of model 1 and will transfer it to the original state. In addition, this pulse passes through the element And 12, will go to the input of the installation in the “1” trigger 18 model 1 and will reset the trigger 18 to its original state. Thus, the device went into standby mode.

The operation of the device when locking ships from the lower to the upper pool is as follows. The simulation begins by turning on the generator 21 of model 20a (the generator 21 of model 20 is turned off), which generates sequences of random pulses that adequately reflect the laws of receipt of lock requests from downstream vessels. The pulses from the output of the generator 21 are fed to the summing input of the reverse counter 22, the bit outputs of which are connected to the corresponding inputs of the decoder 23, the number of which is n, and the number N ₂ = 2 ⁿ , which are connected to the corresponding inputs of the OR element 24. Using the combination of elements: generator 21, a reverse counter 22, a decoder 23 and an OR element 24 of model 20a, the process of queuing vessels in a downstream N2 length is simulated.

If there is at least one unit (one vessel) at the first output of the reverse counter 22 of model 20a, a high potential appears, which through the first input-first output of the decoder 23 enters through the OR element 24 of model 20a to the second input of the element And 5 of model 1, opening it, and also, from the output of the OR element 24, through the second input of the OR element 16, it enters the second input of the open And 3 element and then goes to the single input of trigger 2, translating it into a position in which a low potential appears on its direct output, And 3 closes on the first entry, indicating element 14 detects the end of finding a standby gateway. The high potential from the output of the And 3 element simultaneously arrives at the first input of the And 4 And 5 elements. Since the And 4 element is closed on the second input, because the output of the OR element 24 of model 20 is zero potential, there will be no signal at the output of the And 4 element and through the And 11 element, the generator 6 will not be started. Since the And 5 element at the second input is open, the signal (high potential) received from the output of the And 3 element to the first input of the And 5 open element passes through the second input of the And 10 open element to the start input of the generator 7.

After some random time, a single impulse appears at the output of the generator 7, simulating the moment of making a decision and issuing permission to lock ships from the bottom up by the dispatcher of the central gateway control panel. The pulse from the output of the generator 7 is supplied to the input of the installation in “0” of the trigger 19 and puts it in a position where the element And 9 of model 1 opens at the first input, the element And 36 at the second input and the element And 37 of model 34a at the first input, the stop input of the generator 6, to the second input of the AND element 42 of the model 41, as well as to the second input of the And 29 element open at the first input of the model 25a. Depending on the length of the line of vessels in the downstream, the operation of the device is as follows.

If in the line of the downstream of the vessels N ₀ <N, then the pulse from the output of the And element 29 of model 25a will pass through the delay element 30, opened by the trigger 33 at the inverse input of the And 26 element, the second input of the OR element 32 of the 25a model and will go to the second input of the OR element 59 of the model 52 and then passes through the second input of the And 57 element open at the first, third and fourth inputs to the installation input in the “0” trigger 56 of the 52 model, puts it into a state in which the And 57 element closes at the first input, and also input 581 ** of the preparation unit 58 (the first input of the element OR 73) model 52, simulating the beginning of the preparation of the first lock chamber for the passage of ships from the bottom up.

After some random time, adequate to the preparation time of the first lock chamber for passage of vessels from the bottom up, a single pulse appears at the output * 583 of the preparation unit 58 (the output of element And 76) of model 52, which, through the delay element 40 of model 34, enters the installation input to "1 "trigger 56 of model 52 and sets it to its initial state, opening the And 57 element at the first input, and also goes to the first input of the And 35 element of model 34 open on the second input and then through the OR element 38 of model 34, the second input is open at the first input element And 37 and the OR element 39 of model 34a passes to the subtracting input of the reverse pulse counter 22 of model 20a, thereby simulating the vessel's exit from the downstream line to the first lock chamber.

The pulse from the output 58 _{3 of the} block 58 for preparing the model 52 also arrives at the first input of the And 46 element of the Model 45, and through the delay element 60 of the Model 53 to the first input of the open And 61 element and then through the OR element 63 of the model 53 to the installation input in "1" trigger 71 of model 55, which translates it into a position in which a high potential appears on its inverse output and the indication element 70 simulates a resolution signal for the vessel to enter from the downstream into the first chamber.

The pulse from the output of the OR element 63 also enters through the open And 62 element to the installation input in the "0" trigger 65 model 53, puts it in a state in which the And 62 element closes at the first input, and the And 57 element - at the third. After some random time after the start of generator 64 of model 53, adequate to the time the vessel entered the first lock chamber, moored the vessel and closed the lower gates of the first lock chamber, an impulse appears at the output of generator 64, which will arrive at the input to the “0” setting of trigger 71 of model 55 and translates it into a position in which the display of the display elements 69 and 70 corresponding to the prohibiting signal of the traffic light for the vessel to enter the first chamber of the lock changes.

The pulse from the output of the generator 64 of model 53 is also fed to the input of the trigger in the “1” trigger 65 of model 53, resetting it to its original state, thereby opening the And 57 element of model 52 and the And element 62 of model 53 at the third input. The pulse from the output of generator 64 also enters the second input of the open element And 67 of the model 54 and starts the generator 68 of the model 54, at the same time enters the input of the installation in the "0" trigger 66, translating it into a position in which the And 67 element closes at the first input, and the And 57 element of the model 52 - on the fourth entrance. After some random time, adequate to the time of filling the first chamber of the lock, opening the upper gate, launching the vessel and entering the upper pool, the generator 68 gives a single pulse, which, entering the input of the unit in “1” of the trigger 66, transfers it to its original state and element And 67 of model 54 opens at the first input, and element 57 of model 52 opens at the fourth input, also this pulse goes through the first input of element OR 17 of model 1 to the second inputs of elements And 8, And 9 of model 1. Since element And 8 is closed the first entrance is prohibited voltage from the trigger 18, and the element 9 is opened by the enable voltage from the output of the trigger 19, the pulse from the output of the OR element 17 will pass through the element 9, the second input of the OR element 15 to the installation input in the “0” trigger 2 model 1 and translate it in a state in which a high potential appears at the first input of the And 3 element of model 1, i.e. The device has entered standby mode. Further, the device operates automatically when passing ships from top to bottom, i.e. the cycle repeats.

If in the line of the downstream vessels N ₀ ≥N ₁ , then the second chamber is included in the locking process and the device operates as follows. The pulse from the output of the generator 68 of model 54a, simulating the output of the vessel from the first lock chamber to the upstream, passes the OR element 17 of model 1 and goes to the second input of the open element And 9 of model 1, then through the elements of OR 15 to the input of the trigger 2, transfers it to the position in which the And 3 element opens, the high potential (signal) from the output of the OR element 24 of model 20a, passing through the elements OR 16, I3, I5, I10, model 1, is input to the start of the generator 7, whose output, after a random time, an impulse appears. This pulse enters through the second input of the open element And 29 of the model 25A to the inputs of the delay elements 30, 31.

Since there is N ₀ ≥N ₁ in the downstream, the high potential from the N ₁ output of the decoder 23 of model 20a will transfer the trigger 33 of model 25a to the state in which the And 26 element closes at the inverse input, the And 27, And 28 elements open at first entrances. Then the pulse from the output of the delay element 31 enters the second input of the open element AND 27 of the model 25a and passes to the second input of the OR element 59 of the model 52a, i.e. the second camera of the gateway is turned on and it begins to function similarly to the first described above. At the same time, the pulse from the output of the AND element 29 of model 25a enters through the delay element 30 to the second input of the open And 28 element and through the OR 32 element to the second input of the OR element 59 of model 52, i.e. the first camera continues to function and the device operates as described above. Thus, the inclusion of the second chamber of the two-chamber gateway and the joint operation of two cameras of the gateway simultaneously when locking ships from the bottom up is realized.

When reducing the queue of ships N ₀ to N ₁ -1 there is a reverse switching of the gateway cameras, i.e. after the ship’s lock No. ₁ , the operation of the second lock chamber ceases, the first lock continues to lock. This is achieved by the fact that the high potential that appears at the (N ₁ -1) -m output of the decoder 23 of model 20a and arrives at the input of the installation at “0” of trigger 33 of model 25a, throws it into a state in which the And 26 element opens and closes at the first entrance the elements I 27 and I 28 of the model 25 a. Further, the device operates as described.

When locking from the line of the downstream of the last vessel, the device operates as follows. The pulse from the output 85 of the preparation unit 58 of the model 52 through the delay element 40, the element And 35, OR 38 of the model 34, the second input of the open element And 37, OR 39 of the model 34a is fed to the subtracting input of the reverse counter 22 of the model 20a, resulting in the output of the element OR 24 of model 20a there will be zero potential and the element AND 13 of model 1 will open at the inverse input. The same pulse from the output 58 of block 58 of preparation 52, having passed, as described above, the path through the elements of models 53, 54, 1, will go through the elements AND 9, OR 15 to the installation input in the “0” trigger 2 of model 1 and translate it in the initial state. In addition, the same pulse from the output of the And 9 element will pass through the open And 13 element of model 1 and will transfer the trigger 19 to its original state. Thus, the device went into standby mode.

If the moments of the appearance of pulses at the output 58 _{3 of} block 58 of models 52 and 52a coincide, then in this case model 45 of the device comes into operation both when locking from top to bottom and when locking from bottom to top. Model 45 is designed to correctly take into account (not lose) vessels that have left the line of the upper (lower) downstream simultaneously into the first and second chambers of the gateway. Suppose that pulses appeared simultaneously at the outputs 58 of ₃ blocks 58 of preparation 58 of models 52 and 52a, then a pulse appears at the output of element 46 of model 45, which puts trigger 50 into a state in which element 47 of model 45 opens and elements 35 models 34.34a and elements And 61 models 53, 53a are closed. Then the pulse that appeared simultaneously at the output 58 ₃ of the training unit 58 of models 52 and 52a (i.e., coinciding in one, but simulating two vessels that left the queue), will not go to the subtracting input of the corresponding reversible counter 22 of model 20 and 20a, thereby excluding the loss of one of the two vessels, simultaneously leaving the line of the upper or lower pools.

The pulse from the output of the And 46 element, passing the OR 51 elements of the Model 45, OR 38, AND 36, OR 39 of the Model 34 (34a), goes to the subtracting input of the reverse pulse counter 22 of the model 20 (20a), thereby simulating the exit of one vessel from the queue upstream (lower) downstream into the gateway chamber. The same pulse from the output of the OR element 51 of model 45 passes the delay element 49, the open element AND 47 of the model 45, the elements OR 38, AND 36, OR 39 of the model 34 (34a) and is fed to the subtracting input of the reverse pulse counter 22 of the model 20 (20a) thereby simulating the exit of another vessel from the queue of the upper (lower) downstream to the lock chamber, thereby achieving the correct accounting of outgoing vessels from the queues of the upper (lower) downstream and coming to the lock chamber in the situation under consideration.

To continue the operation of the gateway cameras in this situation, the pulse from the output of the OR element 51 of the model 45 is then fed to the second input of the OR element 63 of the model 53 and through the delay elements 49, AND 47 of the model 45 to the second input of the OR element 63 of the model 53a. The pulse from the output of the And element 46 of model 45, having passed the delay element 48, transfers the trigger 50 to its original state. Further, the device operates as described above.

To exclude situations when a decision was made to lock with one or two cameras from bottom to top and top to bottom, element I 42 and delay element 43 were simultaneously introduced into the device. Suppose that at the output of generators 6 and 7 of model 1, pulses appeared at the output of the stop of generators 7 and 6 respectively, and the inputs of aND gate model 42 41, the output of which appears a pulse pattern which extends the delay element 43 and 41 is supplied to the stop input 58 ₂ 58 blocks training patterns 52 and 52a, thereby eliminating the development described in Chez situation.

To restore the initial state, the pulse from the output of the delay element 43 of the model 41 is supplied through the third input of the OR element 15 of model 1 to the input of the setting in “0” of trigger 2, resetting it to its initial state, then the device continues to work automatically.

Alternating locking of N vessels from top to bottom and N vessels from bottom to top. Let's say there is a lock from the line of the upstream of all N vessels (from top to bottom), and then from the line of downstream of all N vessels (from bottom to top). The device operates as follows. An impulse simulating the output of the last vessel from the upstream line is received from the output 58 ₃ of the preparation unit 58 of model 52 through delay elements 40, AND 35, OR 38, AND 36, OR 39 of model 34 to the subtracting input of the reverse pulse counter 22 of model 20, to the output of the OR element 24 of model 20 appears zero potential, i.e. And element 12 opens at the inverse input, then the pulse from the output of generator 68 of model 54, simulating the output of the last vessel from the first lock chamber to the downstream, passing elements OR 17, AND 8, OR 15 of model 1, transfers trigger 2 to its original state, opening on the first input, element And 3. At the same time, the pulse from the output of element And 8 of model 1, passing through element And 12, is fed to the installation input in trigger 1 of “18”, as a result, element And 10 opens, and element And 8 of model 1 closes.

Since the elements And 3, And 5 of model 1 are open on the second input, the high potential from the output of the element OR 24 of model 20a is transmitted through the elements OR 16, I3, I5, I10 to the input of the start of the generator 7. The pulse from the output of the generator 7 transfers the trigger 19 to the position in which the And 9 element is open at the first input and the And 11 element is closed at the first input. Further, the device operates automatically as when locking from the bottom up. If, at the moment of locking from the bottom up in the upper pool, a queue of vessels has formed, the device automatically switches to locking from top to bottom after passing all vessels from the line of the lower pool according to the scheme described above. Other modes of operation of the device are similar to those considered.

The statistical characteristics of the processes of functioning of a two-chamber shipping lock, both absolutely reliable and unreliable (failures and their elimination during preparation), taking into account the dynamics and specifics of its application, can be determined by the readings of meters connected to various elements of the device. The obtained statistical characteristics for various laws of distribution of random time intervals of the functioning processes of both absolutely reliable and unreliable two-chamber shipping locks, taking into account the dynamics and specifics of its application, allow solving the problems of estimating, predicting and ensuring performance indicators of two-chamber shipping locks, for example, efficiency, throughput ability, readiness, reliability and others.

Thus, as can be seen from the description of the operation of the device, the specified technical result is achieved.
