Description

one

The invention relates to the means of automating the process of passenger transportation and is intended to operate in an automated control system.

A device for controlling the mode of operation of an escalator belt is known, which contains sensors for monitoring incoming and outgoing passengers, connected to an executive unit, the output of which is connected to the input of the signal unit fl.

A disadvantage of the known device is the limitation of the ability of the escalator due to the possibility of changing only the speed of movement of one tape.

The purpose of the invention is to increase the throughput of escalators.

This goal is achieved by the fact that the device is equipped with a switch with an indication unit and an operating mode selection unit containing counters of incoming and outgoing passengers, blocking for these counters, descent and ascending counters, decoders, generator and counter of such impulses, block coincidences for a clock counter and a time delay block, with the outputs of the sensors of the incoming and outgoing passengers being connected to the inputs of the counters of the incoming and outgoing passengers, respectively, the outputs of each of which are connected The inputs of one of the group of blocks of coincidence, the outputs of the blocks of coincidence of one and the other group are connected respectively to the inputs of the descent and lift mode counters, and the outputs of the latter are connected to the inputs of the decoders, the clock generator is connected to the input of the clock counter, whose outputs are connected to by inputs

Block 5 of the counter of this counter / output of the block of coincidence is connected to the input of the block of time lag and one of the inputs of both decoders, the outputs of which are connected to the inputs

0 of the switch connected by the outputs to the inputs of the display unit and the execution unit, and the output of the time delay block is connected to the second inputs of the clock counter,

5 counters for descent and ascent mode and counters for incoming and outgoing passengers.

The drawing shows the function 30. The scheme of the proposed device

for adjusting the operating modes of the underground catalysts.

The device contains sensors 1 and 2 of monitoring incoming and outgoing passengers, unit 3 for selecting the operating mode, including counters 4 and 5 for incoming and outgoing passengers, blocks 6-11, coinciding counters 12 and 13 for descending and lifting, decoders 14 and 15, a clock generator 16, a clock counter 17, a coincidence unit 18, a time holding unit 19, a switch 20, an indication unit 21, an execution unit 22, a signaling unit 23,

The device implements four modes of escalator slope per descent: 1 mode - one tape is enabled per descent at speed V,

IIrezhim - included one tape on the descent with the speed of V, -, (a -1)

III mode included two tapes on descent with. Speed V, IV mode included two tapes on descent with speed V /). The four modes of operation of the escalator slope are similar, the values for the carrying capacity of the escalator slope for all four modes of operation are laid in the mode selector

at speeds V and Vs Ka, the filling factor of the tape, t is the length of time, in

during which the counting of passengers was carried out.

The device works as follows.

The data on the incoming and outgoing passengers in the form of pulses comes from sensors 1 and 2 of the control of incoming and outgoing passengers to the operation mode selection block 3, respectively to the inputs of counters 4 and 5, the entrance of their and outgoing passengers, signals from the counter 4 of the incoming passengers is delivered to the inputs of blocks 6, 7 and a match; the signals from the counter 5 of the exit passengers are input to the blocks of 9, 10 and 11 matches. Blocks b, 7, and 8 matches are respectively configured for Glgx (AND) values. yvh (AND I) and fte- (IV), calculated by the formula (1), when the counter 4 incoming passengers counts (I) the output of the block b matches a single pulse occurs, which arrives at one of the inputs of the counter 12 modes

descent and unit recording in it. At the moment when the counter of 4 incoming passengers records a number equal to IVA (III), a single impulse from the output of block 7 of coincidence will enter 12 counter modes at the input of the counter and it will contain the recorded number two. With UBX (), a single impulse at the output of block 8 matches another impulse to the counter of 12 descent modes, i.e., the number will now be written in it, the Counter of the 12 descent modes is decrypted using descrambler 14. Zero in the counter of 12 descent modes is decrypted as choice of 1 mode, unit - choice of II mode, two - choice of III mode, three choice of IV mode. Similarly, the mode selector for escalator belts operating on the rise functions.

The issuance of information about the selected modes of operation is as follows,

In block 3, the mode of operation includes a generator of 16 clock (second) pulses. The counting of the number of clock pulses occurs in the counter 17 clock pulses. B, the moment when the latter counts some predetermined time interval t, a single impulse appears at the output of the coincidence unit 18. It enters the decoders 14 and 15 and allows the transfer of information about the selected modes of operation of the escalator slope on the descent and ascent. This single impulse arriving through time delay unit 19 to counters 4 and 5 of incoming and outgoing passengers, counters 12 and 13 of descent and ascent modes, counter 17 clock pulses, brings them to the zero state. After this block. 3 mode selection is ready for a new cycle. .

. The selected values, no escalator tilt modes of descent and ascent, go to switch 20, and from it to display unit 21 and to executive unit 22, which directly controls escalator tilt, providing a stop, start, change of direction or speed of movement of escalator tapes. . For the safety of passengers, all the switchings made in the executive unit 22, in the form of corresponding signals, go to the alarm unit 23, which alerts the dispatcher and the passengers. Dispatcher j monitors the information provided by the display unit 21 and can interfere with the operation of the device by manually making the necessary switchings on the switch 20.
