The invention is intended to automatically regulate the operation of escalator tracks mainly in the descent mode and may be unused on metros in a changing passenger traffic environment.

The purpose of the invention is to increase the accuracy of controlling the modes of operation of the escalator tracks by counting passengers separately at different time intervals of their passage.

The drawing shows a diagram of the proposed device.

The device contains sensors for passenger passage 1, connected to the input of the first element OR 2, the first 3, the second 4 and the third 5 counters of the number of passengers whose exits are connected to the first 6, second 7 and third 8 elements, time relay 9, executive unit 10, the second element OR 11, the separating trigger 12, the inputs of which are connected to the output of the first element OR 2, the fourth 13th, the fifth, 14th, the sixth 15, the seventh 16, the eighth 17, the ninth 18, the tenth 19 and the eleventh 20 elements And, one separation trigger output 12 is connected with a quarter of 13, ninth of 18, tenth of 19 and one the eleventh 20 elements are And, and the other output is with the fifth 14, sixth 15, seventh 16 and eighth 17 elements I. The master oscillator 21 time intervals and the outputs of the split trigger 12 through the fourth element And 13 are connected to the input of the counter 22 duration of odd time intervals , and through the eighth element And 17 - with a counter 23 of the duration of even time intervals. The first, second and third outputs of the counter 22 are the lengths of odd time intervals through the fifth 14, the sixteenth and seventh 16 elements AND, and the first, second and third outputs of the counter 23 are the lengths of even time intervals through the ninth 18, the tenth 19 and eleventh 20 elements And respectively are associated with the inputs of the first 3, second 4 and third 5 counters of the number of passengers, the outputs of which are associated respectively with one input of the first 6, second 7 and three 8 elements, the other inputs of which are connected with the outputs of time relay 9. The outputs of the first 6 and second 7 elements are associated with the executive

unit 10 directly, and the output of the third element AND 8 via the second element OR 11, the outputs of the first 3, second 4 and third 5 counters of the number of passengers are connected respectively to the inputs of the first 24, second 25 and third 26 counters of the counting cycles by the memory trigger 27, and also the twelfth 28, thirteenth 29 and fourteenth 30 elements I.Vyhody p 14, sixth 15, seventh 16, nineth 18, tenth 19 and eleventh 20 elements And through the separation diodes 31-33 connected to the installation inputs of the counters 22 and 23 , as well as with the inputs of the first 3, second 4 and retego 5 meters number of passengers. The outputs of the execution unit 10 through the third element OR 34 and the differentiating element 35 are connected with the installation inputs of the time relay 9, the split trigger 12, the first 24, the second 25 and the third 26 cycle counters, as well as the memory trigger 27.

The device works as follows.

Passenger passage sensors during the passage of each passenger to descend on the escalator produce electrical impulses that through the second element OR 2 arrive at the input of the separation trigger 12, which is switched on by the counting circuit, and when passing each passenger is transferred to another state. As sensors 1 can be used the existing automatic control points of the automatic transmission installed on the subways. When the first passenger passes, the separation trigger 12 is moved to another state. At the same time, a permitting signal arrives at one input of the fourth element AND 13, and therefore the pulses of the master oscillator 21 of the time intervals begin to arrive at the input of the counter 22 of the length of the odd time intervals, which starts counting pulses until the second passenger follows sensor 1. At the time of the passage of the second passenger, the breakaway trigger 12 enters another state, the enabling signal from the input of the fourth element And 13 is removed and appears at the input of the eighth element And 17. As a result, sy from the oscillator 21

time intervals cease to arrive at the counter 22 of the duration of even-numbered time intervals, it stops counting, and begins to arrive at the input of counter 23 of the duration of the fourth time intervals, which begins to count pulses.

At this time, information about the duration of the time interval between the first and second passengers is read from one of the three outputs of the counter 22 for the duration of odd time intervals. If the counter 22 captures the time interval in the range O - i ,, the signal is present at the first output, if from ij to i - at the second output, and if more than i from the third output. The signal from the output of the counter 22, the duration of odd time intervals, is transmitted through one of the elements I (Fifth 14, Sixth 15 or Seventh 16) to the corresponding counter of the number of passengers (first 3, second 4 or third 5), and one is written to one of them j testifying to the passage of one person.

The permission to read information from the output of the counter 22 of the duration of odd time intervals is applied simultaneously to the inputs of the fifth 14, sixth 15 and seventh 16 elements And from the output of the split trigger 12 after the second passenger enters. As the third passenger passes, the separation trigger is again thrown. The eighth element AND 17 closes, and the fourth element And 13 opens. The pulses of the master oscillator 21 time intervals cease to arrive at the counter 23 of the length of the even time intervals and it stops counting, and the counter 22 of the duration of the odd time intervals starts to count the pulses of the master oscillator of the 22 time intervals. Information from one of the outputs of counter 23 for the duration of even time intervals is read through the ninth 18, tenth 19 and eleventh 20 And elements to the corresponding passenger number counter (first 3, second 4 or third 5), and the same unit is written again. Thus, the first 3, second 4 and third 5 counters of the number of passengers are gradually recorded units arriving

from counters 22 odd and 23 even time intervals. At the same time, in the first counter 3, the numbers of passengers are recorded passengers, 11-1111 with intervals O - i, i.e. the shortest following intervals. In the second counter, 4, the numbers of passengers are recorded passengers, proceeding at intervals within i, -i. The third counter 5 of the number of passengers records the passengers with the largest intervals in excess of i. Thus, the first 3, second 4 and third 5 counters of the number of passengers simultaneously, until they are completely filled, consider the number of passengers entering the escalator, in accordance with the three fixed ranges of time slots recorded by the counters of odd and even time intervals.

As soon as any of the counters 3-5 of the number of passengers appears to be filled, a signal appears at its output, which is fed respectively to the input of the first 6, second 7 or third 8 elements I. So that the output of the first 6, second 7 or third 8 elements And according to the signal, the simultaneous presence of the number of passengers on the outputs of the counters 3-5, the time relay 9 and the counters 24-26 of the number of counting cycles on the three inputs is necessary. Therefore, the signal from the output of the first 3, second 4 or third 5 counters of the number of passengers does not open the first 6, second 7 or third 8. And elements, but is fed to the input of the corresponding first 24, second 25 or third 26 counters of the number of counting cycles. As a result, in the corresponding counters 24-26 of the counting cycles, the unit is recorded, and the signal from the outputs of the counters 24-26 of the counting cycles, the filled counters 3-5 of the number of passengers are set to the zero state.

In order to eliminate unnecessarily fast switching of operating modes and to make the escalator work more smooth, multiple (in the proposed device threefold) filling in the counters of the number of passengers is provided. After one of the three counters of the number of passengers is filled three times, in accordance with the counter of the number of counting cycles, the number three is recorded. If the first counter 3 of the number of passengers is filled three times, from its output and from the output of the first counter 24 the number of counting cycles to the input of the first element 6 comes the enabling signals. If simultaneously with these signals, an output signal is present at the first output of time relay 9, a signal arrives at the output of the first element 6 and arrives at the execution unit 10 and switches on the first, most efficient mode of operation when both escalators with maximum speed are operating. The performance of the escalator in the first mode of operation can be expressed by dependence

exceeds the capacity of the second counter And the number of passengers. If during a period of time O - t ,, when a signal is present at the first time relay 9, neither the first 3 nor the second 4 counters of the number of passengers are filled to the end, the control signal from the outputs of the first 6 or second 7 elements (0 And the executive unit 10 is not received.

where P is the ability of one escalator tape at the speed of movement k is the filling factor of the escalator;

The time t is chosen according to the length of the passenger’s descent (ascent) on the escalator. If the second counter 4 of the number of passengers is filled three times, from its output and from the output of the second counter 25 the number of counting cycles to the input of the second element And 7 are received permitting signals. If at the same time, an output signal is present at the first time relay output 9, a signal arrives at the output of the second element And 7, arriving at the executive unit 10 and activating the second mode of operation, when one escalator is operating at maximum speed V.

the counters of the number of passengers were not filled three times during the period of time O - s, and the third counter is 5 the number of passengers during the period t - t, the mode does not switch and the relay

9 time continues to work. The signal from its second output is turned off and after a time tj appears at its third output and is fed to one inputs of the twelfth 28th and thirteenth 29 And elements, to the other inputs of which signals are sent respectively from the first and second outputs of the memory trigger 27. The input of the latter is connected with one output separating trigger 12.

The memory trigger 27 has only one separator input and is triggered once per cycle of operation of the device in the event that

Passenger passage sensors 1 sense at least one Lassagier and the separating trigger 12 passes at least once into another state. In principle, the signal at the input of the memory trigger 27 is present at the entry of each odd passenger, but the trigger 27, once exchanged, remains in this state. If the passengers pass sensor 1 does not fix a single passenger, the memory trigger 27 will remain in its original state. If the device captures the passenger's input, the memory trigger 27 is reset and the signal from its first output goes to the input of the twelfth element AND 28. If this signal coincides with the signal from the third time relay output 9, the control command from the output of the twelfth element And 28 through the second the OR 11 element is fed to the input of the execution unit 10 to activate the third mode of escalator operation. If the device has not registered a single passenger, the memory trigger 27 remains in its initial state, there is no signal at its first output, and the signal from its second output enters the input of the thirteenth element I 29, from the output of which, in case of coincidence with the signal From the third time relay output 9, a stop command is sent to the input of the execution unit 10 to stop the operating escalator. The latter remains stopped until the first passenger enters, at the entrance of which the separation trigger 12 is transferred to another state, as a result of which the memory trigger 27 changes to another state and sends a signal to one input of the fourteenth element I 20,

The counting of the odd and even time intervals into the zero state is carried out each time at the moment of recording information into the first 3, second 4 or third 5 counters of the number of passengers through dividing diodes 31-33. The installation of the first 3, the second 4 and the third 5 counters of the number of passengers in the zero state is effected by a signal from the first 24, second 25 or third 26 counters of the counting cycle, relay 9 of time separating 12 and storing 27 triggers

and occurs at the end of each counting cycle, i.e. each time the escalator mode is switched by a signal from the output of the execution unit 10, which is supplied to these blocks through the third element OR 34 and differentiating element 35. And in the absence of passengers, the escalators are not included, and after the appearance of passengers, they are turned on again.
