Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) P 190999 ^ .6 (71) Otis Elevator Company, One Financial Plaza, Hartford, Connecticut 06101, USA (72) Joris Theodor Schröder, Berlin, Heinz-Dieter Rogalski, Berlin,

This invention relates to elevators and in particular to automatic elevator control systems.

The present invention is directed to a multi-elevator car elevator system in which the starting and stopping of cars under certain conditions takes place on the basis of calls which are recorded. Such systems, as a result of the start-up of one car, cause a first call from the record to appear in the system and set one or more cars in motion as certain traffic needs arise. In the past, in certain traffic situations, these systems have often resulted in an insufficient number of elevator cars to ensure a fast and efficient service.

Accordingly, it is an object of the present invention to provide a system for increasing the operational efficiency of elevators under certain traffic conditions.

The features of the control system according to the invention appear from the appended claims.

In a preferred embodiment of the present invention, the baskets are assigned to a variable zone building. These zones most preferably consist of a zone of the ground floor comprising the street level of the building and any basement layer and the level of the lower basement and one or more 2,57576 upper zones divided into a part of the upper floors. One of the elevator cars has been assigned to each zone to operate on the basis of the traffic calls that arise from that zone and the other elevator cars in the system are excluded. In addition to this, each elevator car serves any floor of the building as a result of commands from its elevator car command circuits. When a designated elevator car operates in the area of its assigned zone, it will not normally be able to operate on the basis of calls recorded from the layers below that zone, and all elevator * and below that zone will be prevented from operating on the basis of floor calls recorded from that car zone. However, any elevator car may end up in any zone as a result of commands given from its own elevator car. Thus, as a result, when a given elevator car leaves its zone as a result of an instruction given from the elevator car, a different elevator car that is currently unassigned to any zone is able to move to that zone and be assigned to it. If it is necessary to cause an already designated but unused elevator car to leave its assigned zone to answer floor calls in a temporarily unnamed adjacent zone.

According to the present invention, there is provided an elevator control system for a plurality of elevators operating on the basis of individual start switches, thereby serving a plurality of floor levels in a given building from motion and stopping as a result of calls recorded from and from those elevator baskets, this system already dividing those floors. the system includes control devices associated with a naming switch portion for each individual elevator car separately when each of them operates when the associated elevator car is located in a particular zone where it is the only elevator car present, zone switches for each operating zone and each zone the parts of the designation switch for a particular car in this zone are turned on, with each part of the designation of the zone switch having the effect of limiting the response t as a result of the operation floor calls recorded from this zone to the elevator cars located there, each of these designation switch parts in its unattached state elevator cars for those different zones. The system is characterized in that the system includes traffic indicating devices separately for each zone when each of these enters into operation due to the assigned amount of 5,57576 traffic in this partitioned zone, and provided that the elevator car naming switch is turned on and that the elevator car is not currently operating in response to a call from the elevator car or floor.

A more complete understanding of the preferred embodiment of the present invention in the illustrated three elevator car array can be obtained from the description below, as well as certain features and advantages thereof, and should be read in conjunction with the accompanying drawings, in which Figure 1 is a simplified schematic diagram of a power supply. with these circuits being identical for all elevators, Figures 2, 3 and 4 together form a simplified schematic circuit diagram of one of the elevator operating circuits, some circuits being common to all elevators, Figure 3 is a simplified schematic switch diagram of elevator car command circuits for one of the elevators, Figure 6 is a simplified diagram of floor-level call circuits to one of the elevators, with some of the circuits being common to all elevators, Figures 7 and 10 are simplified schematic switch diagrams a of the circuits for one elevator that control the operation of the system for different traffic situations, Figures 8 and 11 are simplified schematic circuit diagrams of each of the circuits indicating a high call frequency from the elevator car together with the elevators and further with common circuits for all elevators controlling the system for different traffic conditions; Fig. 9 is a simplified schematic switch diagram of circuits indicating a tight need for multiplier level calls in a zone of a building, and Figs. 12, 13 and 14 are key views of other figures in the diagram showing the windings and tips of relays and switches in vertical detail.

To facilitate understanding of one embodiment of the present invention, the illustrated control system has been greatly simplified from what would be used in a complete commercial installation. It should therefore be noted that in applying this invention to various types of control systems, a number of changes may be made, particularly when applied to more complex arrangements, without departing from its purpose and principles of operation.

The electromagnetic switches used in this illustrated system are marked with the following references: ADV - forward shift switch ASR - automatic start switch BLZ - ground floor zone switch BR - brake release switch C - voltage switch CZL switch CCZ - main zone body locator relay CMZ - center zone body locator relay CPR - call pickup relay CTZ - top zone body locator relay D - down direction switch DG - direction hold switch DGD - auxiliary down switch DOU - auxiliary up switch DGU - auxiliary up first speed switch 2E - second speed switch ETS - excitation time switch PLC - false alarm switch GH - door closing limit switch GUD - group up switch E - field and braking switch HCR - floor level call relay HG - upper body call switch HJ - upper call switch HJX - upper floor hall call switch HS - floor level stop switch HR - top call reversing switch HRX - auxiliary top call reversing switch HZP - upper zone priority relay LCCR - main level car caller relay LG - lower car call 5 switch LR - lowest call rotary switch MGP - MG device priority switch MGT - MG device time relay MGZ - group center zone relay MLGZ - group lowest main floor street level zone relay MLU - main level up directional switch MLZ - main level zone switch MZZ - main level zone switch switch NT - door open switch PM - latch magnet (on selector) PMY - latch magnet relay RUN - operating relay SC - selector switch TGZ - group top zone relay TLZ - zone top floor switch TZ - top zone switch U - up zone switch U - up zone switch U - up zone switch U - start and door open switch XZLP - first auxiliary main zone ordering relay XZP - auxiliary zone priority relay ZLP - ground floor zone ordering relay ZLPX - second auxiliary main zone ordering relay ZMP - middle zone ordering relay ZMP - middle zone ordering relay ZMPX - auxiliary ordering relay ZTPX - assisted top zone ordering relay

Throughout the explanation below, these letters are attached to the above relays and Switches and, in some cases, to their windings. When reference numbers are attached to them, these letters also refer to the switch tips of these relays and switches. The circuits for the windings and all the switches and relays whose operation is related to the whole group are shown in the figures. However, for simplicity, instead of presenting three separate sets of circuits that perform the functions typical of each individual elevator, only one circuit representing these circuits is shown, and it is to be understood that similar corresponding sets are provided for each elevator car. In some parts of the drawing, certain circuits associated with a single elevator are shown in connection with equipment associated with other elevators in the group. In order to distinguish the equipment contained in the various lifts, these circuits have the lower case letters "a", "bM and" c "attached to the reference markings to indicate the corresponding equipment. The whole description also distinguishes the different parts of the lifts by connecting the corresponding lower case letters" a "," b "and" c "to the reference marks referring to these parts.

The circuits shown in the drawings are shown in a simplified form in which the windings and contact tips of the relays and switches are spaced apart from each other and are grouped in series and in parallel with these being located between the positive and negative voltage conductors. The dependence with the windings and associated contact tips is shown in the "vertical diagrams" shown in Figures 12-16. There, the switches are arranged in vertical columns, with the associated reference entries at the top of the column. A reference numeral is attached to each coil and contact tip. The reference for each contact tip includes a pair of numbers separated by a hyphen, the first of which indicates the switch tip number and the latter the number of the drawing in which it is located. In the case of a coil, only one reference is shown showing the pattern of the drawing. Thus, any coil or contact tip can be easily located by taking it from the figure of its vertical diagram, the horizontal height corresponding to that height of the pattern indicated by the drawing number always for each part.

The electromagnetic switches are illustrated in their off state. The switch DG is of the reversing type and is associated with a drive winding and a return winding. Its clutch tips are shown in its restored operating mode. The winding that turns on the switch DG receives its input power in Fig. 2 from the right hand, while its return windings are fed according to Fig. 2, looking at the rectangle indicating this switch from the left, identified by its reference letters DG. The HS switch has a drive coil and a hold coil. Its holding coil is included in Figure 2, where it is indicated by its corresponding identification letters HS, and the drive coil is included in Figure 6.

The GTJD switch is equipped with two drive windings.

Referring to the drawings now shown, there is shown an operating device in Figure 1 comprising a series-connected winding and a bypass winding ESF and EP, respectively, and a motor winding EA. This exciter device forms part of a conventional series of motor generators and is connected to supply power to various elevator control circuits. The generator of this series has a bypass winding GP connected to the excitation winding via conventional directional control circuits and has a series winding GSEF connected in series in the loop circuit which also includes its motor winding GA and the winding MA from the elevator drive motor. The bypass coil MP of the elevator drive motor is connected across the output terminals of the exciter winding as well as the brake release coil BR, which is supplied from the coupling tips H2. The winding DMA of the elevator door motor and its parallel winding DMF are connected via switching coupling tips to the outputs of the excitation winding which are to be energized when the elevator door is to operate. The contact winding motor winding BMA and the protective windings BMF are connected via switch tips to the output terminals of the wirewound winding so that the operation of the selection switches SLS1, SLS2, SLS3 and SLS4 can be adjusted by the position of the layer selector forwarding plate. This layer selector and the plate moving it forward are both well known in their own structure and operation and are therefore not described in detail in this context. Various output switches and their circuits will be further shown hereinafter and are also shown in Figure 1.

Figure 2 shows the circuit connections for the various control circuits associated with starting and stopping the elevator car as they are associated with each elevator car individually.

Figure 3 denotes an arrangement for determining an adjustment as a result of a call or calls based on the position of the elevator car and viewed from the position of parallel elevator cars in different zones.

It should be noted that the zone contact brushes HB, ZRB and ZSB are each mounted separately for each of the elevator cars and are located on the forward transfer plate of the respective elevator car floor selector. The brushes ZRB and ZSB are constructed so as to come into contact with the next layer level contact $ 5RS and ZSC, respectively) in the direction of movement before they release the above fixed contact. When any of the elevator cars stops at a particular floor, all the brushes in the associated selector are in contact with the fixed contacts cooperating with them that correspond to that floor or platform. The brushes in the forward transfer disk of the selector are located as is well known prior to the synchronous indication of the position of this elevator car to provide an indication of its effective location. In addition to their six functions, the brushes of the forward transfer disk are locked by means of hooking devices in contact with the coupling tips in a certain floor, which must be stopped and held in this position as the elevator car moves to this floor level.

Figure 4 shows details of the circuit arrangements for mobilizing and zoning the various baskets of the array. Fig. 3 shows an arrangement in the circuit of noting the commands given from the elevator car, the circuit of recording and deleting the call, and the circuits for memorizing whether the commands given from the elevator car are either above or below the position of the elevator car. 9 · 8 57576 is somewhat similar to the arrangement of Figure 6 in which it should be considered. The floor call recording and deleting brushes LHB and UHB, the elevator car command recording erasing brush CAB and the top) and the lowest floor calling brushes HHB and LHB are all physically located on the selector forward transfer disk, as are the HHS and LHS switches, which are isolated from the brushes HHB and LHB are mechanically used by these. The HCB of the top and bottom call of the elevator car (Fig. 5), the upper half of which is made of non-conductive material, is located on the same floppy disk and, when connected to the tyrat-Roni XLG and XHG gas pipes, acts to indicate the presence or absence of calls from the elevator car. synchronous) below or above the position.

One set of elevator car and floor level call recording devices is illustrated in Figures ^ and 6. In any apparatus, a separate set of elevator car command devices is installed for each elevator car and a common set of hall level calling devices is installed for the entire group. Each of the call recording devices consists of a cold cathode tube (IU, 2D or 1C), the numerical marking of which indicates the floor level to which it relates when the letter appendix indicates the direction of movement of the elevator car or the position of a part associated with the elevator car. These are actuated by ground capacity when a person touches an electrode outside them, which also acts as a push button TB (3U in Figure 6). Each tube is provided with a load resistor (RUL, RDL or RCL) in its anode circuit to which a voltage is applied as the tube conducts current as a result of the call memory. This voltage is generated at the selector tips CAC as well as the HCC elevator car calls and at the tips UH, DH, HH and LH in the case of floor level calls. The corresponding individual tips of the floor level call selectors (i.e., parts UH, DH, HH, and LH) are installed separately for each of the elevator cars and are cross-connected in the conventional manner, although such cross-connections are not shown for illustrative purposes.

As is known per se, voltage values of 155 volts from line B + to line Bo, 150 volts as an effective value from line Bo to ground voltage in transformer TF secondary windings, 95 volts as an effective value from line Bo to line AG1 and -45 volts from line B to line Bo can be used when in use Cold cathode tubes.

Each call record tube also has a diode and a resistor connected in series from its anode at the end of the connection to a conductor labeled ZC (Fig. 5), ZM or ZT (Fig. 6). These wires are connected to hardware that will be described later.

9 57576 The winding HCR (Fig. 6) from the layer level call relay is connected in series with the anode plate supply by the cold cathode tubes of the layer contact buttons and is adjustable to "pull on", i.e. to operate when a predetermined through the winding. Thus, as a result, the relay acts as a detector when this minimum number of layer calls exists regardless of the direction of these calls. Capacitance Q1 acts as a filter for short and sharp induced surge currents. The capacitance QY and the thyratron tube XCC act as time measuring devices and their function is to make the continuous call switch CC operate after a predetermined number of recorded layer calls has been continuously present for a certain predetermined time. This measurement is useful in indicating traffic needs that are currently believed to be best addressed by a mode of operation other than that provided by the present invention. This switch CC provides easy hardware to switch to another mode of operation that is better suited to changed conditions. Unless otherwise specifically mentioned below, it will be assumed in the following explanation that traffic calls are recorded randomly so that the pipe XCC is not in its conductive state and that the switch CC is incomparable.

In Fig. 7, a coupling tip LV is used with a load sensing switch. They open whenever the load in the associated elevator car exceeds a certain predetermined amount of weight. The elevator car locating contact tips ICC1-ICCT are installed in the device for each elevator car and are mounted on the corresponding elevator car floor selectors at positions corresponding to the floor to which they are associated and indicated by the associated reference number 1-6 and the letter T. Elevator locator the brush ICB is mounted on the floppy disk of the floor selector of the elevator car that pushes it. The interconnected groups of coupling tips ICC2-ICC4 and ICC5-ICCT are constructed so that the brush ICB comes into contact with the next contact tip from the group in the direction of elevator car movement before it leaves the contact tip in the group associated with the previous floor level.

In Figures 8 and 9, conductors B +, Bo, AC1, ZC and ZM form extensions to those conductors identified by the same reference numerals in Figures 5 and 6. The circuitry for the elevator car ground floor call relay LCCRa associated with elevator car "a" is repeated for all other elevator cars in this system. , although this circuit is not shown for simplicity in the figures. The winding for each elevator car floor floor call relay is energized to operate its relay whenever the associated .-: υ '10 57576 elevator car exits the floor floor level upward when a predetermined number of elevator car order calls are recorded or when a predetermined load is involved. It thus remains energized until the elevator car changes its direction of travel from upward to downward. In this way, it forms a load measuring equipment. The circuitry for the first and second auxiliary ground floor ordering relays XZLP and ZLPX windings and the top, middle and main floor calling relays ZTP, ZMP and ZLP, respectively, are common to all elevator cars. The windings of the first and second auxiliary ground floor calling relays XZLP and ZLPX are powered to operate the associated relays whenever the number of elevator cars from which the elevator car ground floor calling relay LCCR is live exceeds the number of elevators with the elevator car ground floor zone Those circuits that operate as described herein provide traffic indicating equipment and a Main Layer level to the zone.

The circuitry in Figure 9 relates to the middle zone, which in the embodiment now described includes layer levels between 2-k. It energizes the middle zone call demand relay ZMPX whenever the number of recorded floor level calls from floor levels 2, 3 and ^ exceeds a certain predetermined number and when the number of elevator cars located in this middle zone is less than a certain predetermined number. This circuitry generates traffic indicating equipment for the middle zone. A similar such circuitry is installed in the system for the upper zone and includes an auxiliary upper zone paging relay ZTPX and switch tips CTZla, CTZlb and CTZlc from the upper zone elevator car locating relays CTZa, CTZb and CTZc, each of which is connected to an individual hZ. This circuit is not shown for simplicity.

The operation of these systems in controlling the start and stop of elevator cars due to calls, as well as the response and return of such calls, is known per se. The typical circuitry required in one elevator car to perform these tasks is shown in the drawing, but any detailed description of this circuit would unnecessarily prolong the present explanation and, as a result, such an explanation has not been performed.

Let us now move on to the way in which the movements of the elevator cars interact with each other and provide the desired service functions for the different zones. Assume that the elevator car "a" is just arriving on the main floor, i.e. the street level floor level, after moving there from the sixth floor floor level in response to a command to go to the street level from the elevator car, that the elevator car "b" is at the second floor level in the middle zone. for subsequent upward movement, i.e. with the switch DGb set, and that the elevator car "c" is then at the level of the main floor, i.e. street level, in the street level zone, with its direction determining and reversing devices also ready for subsequent upward traffic, so that when the elevator car "b" is at the height of the second floor, it is assigned to the middle zone, because the switch MZb of its middle zone (corresponding to the part MZa in Fig. 3, but not shown in the figure) is superimposed. by means of a circuit comprising switch tips MZ2a, MZ2c, a winding MZb selector tips ZSCb2 and a forward transfer plate brush CZBb. This causes the relay MGZ of the middle zone of the array to be turned on via the circuit 'including the contact tips MZ3b and the winding MGZ. As a result, the contact tips MGZ1 and MGZ2 (Fig. 6) in the middle zone separating devices are spaced apart in the call circuits of the upper and lower layer levels.

Also, the main floor layer level zone switch MLZc (not shown but corresponding to the part MLZa) is turned on, because the elevator car "c" is right now at the height of the main floor level and thus has brought the brush ZSBc into contact with the intermediate tip ZSC1c. The contacts MLZ3c are closed in the MLGZ circuit of the MLGZ winding of the main floor level relay of this group, supplying current to it and thus opening the tips MLGZ1 and MLGZ2.

Since there is no elevator car in the uppermost zone, the contact tips TZ3a, Tz3b and TZ3c are open in the winding circuit TGZ and the contact tips TGZ1 and TGZ2 (Fig. 6) are both closed. Attachment of the contact tips TGZ1 connects the call circuits of the upper layer levels from these layers in the uppermost zone to the corresponding circuits for the middle zone floor levels, and the elevator car "bM, which is the middle zone car, is able to respond to floor calls from the middle

Before the elevator car "a" arrived at the main floor level, the contacts U3 (Fig. 3) closed, turning the circuit winding LRa from the lowest call reversing circuit switch to my set sex, when this and via DGD2a. The contact tips LR1a closed to prepare the self-holding circuit for the switch LRa and the contacts LR2a closed to prepare the circuit for energizing the series winding DGa in the directional storage switch. When the elevator car comes to a standstill, the contact tips of the selector SLS 1a are separated from each other, making a winding 12 57576

Ha (Fig. 1) de-energized from the field and brake switch and the contact tips H4a (Fig. 2), when connected to the circuit with the winding RUNa, are also distinguished from each other. This closes the contacts RUN3a in the circuit including the winding DGa from the direction holding switch DGa, which closes this switch and closes the switch tips DG8a (Fig. 1), thus closing the circuit windings MLUa in the main layer plane upward direction switch through the selector tips ZSCla and the forward transfer plate brush ZSBa. Current of the winding MLUa causes the contact tips MLU3a to close, which in turn closes the circuit that passes through the closed tips SC3a for the winding GUD in the group uplink switch GUD. The contact tips GUD4 (corresponding to the parts GUD2 shown in Fig. 2 when this is shown in the circuit of the corresponding winding ASE) are distinguished from each other in the circuit of the winding ASRc. Kim now the switch ASEc opens after its holding time has elapsed, the contact tips open in the ASR3c winding MLUc circuit in the main floor level upward switch for the elevator car "c" (not shown but similar to the switch MLUa winding circuit) removing current from this winding and causing this switch to open. When the switch MLUc opens, it also opens the contact tips MLU2c located in the circuit SCc of the coil in the selector switch for the elevator car "c" (not shown, but similar to the coil circuit of the switch SCa in Fig. 3). When the switch SCc opens, the elevator "c" is no longer assigned to the selected street-level zone elevator car, so that the elevator "a" now becomes selected as the designated street-level zone elevator car when its select switching is activated after its winding SCa is energized. via contact tips MLU2a, ETS4a, SC5b and SC5c. Likewise, the contact tips 4SR2c (Fig. 1) close in the circuit associated with the windings PMc for the latch magnet at the "o" portion of the elevator car, thus closing the contact tips PM1c and thus providing a switching circuit contactor DG9c As this brush & motor rotates, the transfer disk moves forward in the upward direction to close the selector switches SLSlc, etc., and the generator coil GFc is energized, thus causing the elevator car "c" to move upward as a result of being replaced by the elevator car "a". Elevator "c" continues its upward movement until it encounters any "up" call from the floor level, or until it encounters a "down" call from the floor level in the zone to which it is assigned, this call also being the top call from that zone, or if there is an extension unoccupied zones adjacent to the zone to which it is addressed when the call is the highest call from these zones, or until it reaches an unoccupied zone with an elevator car with no call above it in the associated unoccupied zone. In the latter two cases, the elevator stopping apparatus of the elevator car is actuated because, as will be described later below, the reversing switch HRc of the top call of the elevator car is turned on via the contact tips PMY6c (Fig. 3), RUN1c, HJ3c, DGUIc, coil HRc, and one of which branches include contact tips M7,5c or TZ5c or brush ZRBc and top zone selection contacts ZRC5c, etc. and part D0T! 2c.

Which of these circuit branches is used depends on the simultaneous positions of the different elevator cars.

If, when the elevator car "a" comes to a stop at the height of the main floor, the excitation voltage time switch ETSc from the elevator car "c" is disconnected, i.e. in the unused situation, the MG device of the elevator "c" is closed. In such conditions, the elevator car "c" is not started from the main floor level. ASRc will never come loose.I will not move this elevator car.This is because when the contact tips GUDh (not shown but corresponding to the contact tips GUD2) open, starting the timing of the switch ASRc, the priority switch MGP of the MG device (Fig. U) is actuated by the contact tips. Via MLU and ETS5a This causes the contact tips MGP3 (not shown but corresponding to the contact tips MGP1 in the winding SCa circuit) to open from the winding SCa circuit (not shown in the drawings).

Since the contact tips ETShc (not shown but corresponding to the contact tips ETSU in Fig. 3) are also open due to the excitation time switch ETSc in its unattached state, the circuit for winding SCc in the elevator car selector switch "c" is cut off. This opens this switch, causing the contact tips SCi + c (Fig. 1) to close in parallel with the contact tips CUDH once more to close the circuit to the windings ASRc in the automatic start relay for elevator "c", thus preventing its timing from the end. Although under these conditions the elevator "c" is not moved, the elevator "a" that just arrived in the main floor area becomes the elevator car in question and is sent to service because the elevator car "c" upstairs switch MLUc (not shown but corresponding to part of the MLU in the figure) 3) is in its energized state. When the selector switch SCc opens, it closes the contact tips SC3c located in series with the closed contacts MLU3c in the winding GUD circuit to keep the uplink relay energized, and it also closes the contact tips SC5c to close the circuit to the winding SCa. This causes the contact tips SC1a to open in parallel with the contact tips GUD2 and thus allow the automatic start switch ASRa for the elevator "a" to close in time after the door open time has elapsed, this time being determined by the door open switch NTa.

Suppose now that the elevator car "c" is moved as the elevator car "a" arrives at the main floor level and that as the elevator car "c" moves up 1475576 from the height of the sixth floor, a call to down traffic is recorded, which causes the tube 6D to cathode * Tube 6D introducing the control grid of the tube XHJb for the elevator car "b" through the circuit including the rectifiers DR3 and DR4, the contact tips TGZ1, the wires between them and the rectifiers between the adjacent fixed contacts anchors HHb, the contacts HH? b (provided now that the second car "b" is layer), forward transfer plate brush HHBb and resistor R7b. Now that the tube XHJb conducts, the coil HJXb in the upper layer call switch HJXb receives current from the tube anode plate circuit and closes the contact tips HJX1b in the circuit including the coil HJb (Fig. 3) in the higher call switch HJb. This opens the coil of the contact HJ6b coil ASRb (Fig. 2). When the switch ASRb is tripped, wind the FMb (Fig. 1) from the saw magnetic path associated with the selector associated with the elevator car Mb ", Baa now flows through the test chain tips XD06b, ASR2b and ADY2b, causing the forward transfer plate to move upward by the brush motor, again, it receives power through the closed tips PMlb and DG9b.As the forward transfer plate moves the closing selection tips SLSlb, etc. and the elevator car starts moving upwards to respond to the sixth floor call for downlink traffic and is ready to stop for any uplink call from the floor level between it As previously explained, the elevator car "c" is also moving upwards, but now does not move in response to a call from level 6D, because the diverted contacts MGZ1 (Fig. 6) isolate this call 6D from the circuit of incoming calls from those elevators that are centered. below the zone and prevent the cathode voltage of the tube 6L from being supplied to the tube XH Jc to the control lattice before the forward transfer plate brush HHBc reaches the second layer layer level fixed contact HH2c. When the brush HHBc comes into contact with the tip HH2c, the 6D call causes the switch HJc to turn on in the same manner as what the switch HJb had been in operation. When the switch HJc thus operates also follows the elevator "c" to call 6D.

Suppose elevator "b" leaves the middle zone before elevator "c" does so. Its forward transfer brush ZSBb detaches from the contact tip ZSC4b so that the center zone switch MZb opens. The contact tips MZ2b (not shown but corresponding to the contact tips MZ1b, Fig. 3) in the circuit MZc of the winding (not shown but similar to the circuit MZa of the winding in Fig. 3) for the middle zone switch for the elevator car "c" then close and thus close circuit for this winding through the brush ZSBc and the contact tip ZSCc with which it is currently in contact. When this switch MZc is operated, the elevator car "c" is assigned as the elevator car in the middle zone.

15 57576

Continuous upward movement of the elevator car "b" causes the brush ZSBb to come into contact with the tips ZSC5b, thus closing the circuit winding TZb (not shown but similar to the winding TZa circuit in Fig. 3) in the top zone switch to the elevator car Mb "indicating the elevator car b" and this closes the tips TZJb in the circuit including the winding TGZ from the top zone relay TGZ of the array. , which are below the upper zone and as a result only the car "b", which is now the car of the upper zone, is allowed to follow this call. The car "c", which is the car of the middle zone, is no longer able to follow this call because the contact tips TGZ1 have been removed from above the circle of incoming calls out of it. Since there are no calls recorded, the elevator car "c" in the middle zone stops at the next floor level * where it enters in this zone. The elevator car stop "o" is initiated using the rotary switch of its top call, which is caused by the disconnection of the switches HJXc and HJc and the acquisition of the winding HRc flowing through the circuit including the switch tips PMYöc, RUHlc, HJJc, DGUlc and MZ5c. The contact tips HR3c close when the top call rotary switch HRc has operated and close the circuit to the return coil PMc with a latch magnet. This resets the latch magnet in the selector, causing the forwarding plate to stop moving upward and initiating the elevator car "c" stop operations. The elevator car "c" was not stopped as a result of any call and as a result its door moving equipment does not come into operation and its doors do not open when it stops. This is because the switch CFRc is not actuated and its contact tips in the circuit DOc of the switch CPRac therefore remain open.

In the meantime, the elevator car "b" continues its upward movement until it stops when the tip of the forward transfer plate switch HHSb opens when the brush HHBb comes into contact with the fixed tips HH6b, which removes the voltage at the cathode of tube 6D from the tube XHJb control lattice. after half a cycle at the AC voltage applied across the circuit between its cathode and anode and this allows the call switch HJX from the upper layer level to open. When the switch HJXb opens, the tips HJXb also open in the circuit HJb of the coil HJb included in the upper layer level call HJb tips HJ3b for winding HRb with top-level call rotation switch HRb.This circuit includes tips FMY6b, RUN1b, HJ3b, DGUTb and TZ5b.The tips HR4b open in the winding HRXb circuit included in the auxiliary top-layer, 7f'i V.

16 57576 level call to rotary switch HRXb. The tips HR3b thus close, complementing the circuit return coil PMb for the latch magnet associated with the selector associated with the elevator car "h". This latch magnet causes the transfer plate to stop when it returns, removing current from the brush motor winding and also its coil, and thus causing these plates to come into contact with the stop piece at the sixth layer, keeping the transfer plate in this position. Due to the stopping of the forward transfer plate, the elevator "h" is stopped at the sixth floor. The floor level call 6D is restored in a manner known per se by applying the voltage of the cathode XHSb to the cathode of the tube 6D. The switch HRb is also stubborn, powered by the tips HRlb contacts, so that the switch DGb thus resets and the direction of the elevator movement changes.

• At the time the stop occurred, the switch BSb was operated by applying current to the winding HSb on it, preparing for the reset of the layer level call 6D. The tips HS2b closed in the circuit of the coil CPRb (Fig. 2) and the groove CPRb operated. This closed the tips of the CPR2b winding circuit with the door opening switch DOb and when the stop is completed, the elevator car "b" opens its door in a manner known per se to allow the waiting passenger from the sixth floor to enter the elevator car.

In order to illustrate the operation when the elevator car departs from the zone to which it is assigned and at the end of the operation to the zone with the elevator car and which is other than the main floor or street level zone. Suppose now that a passenger entering from the height of the sixth floor presses a button on the third floor. The fact that the tube 3Cb conducts puts the tube XLGb in its conductive state and also supplies current to the winding LGb in the lower command switch LGb of the elevator car. The contacts LG1b (Fig. 3) are closed, as a result of which the switch Ub operates by opening the contact tips LJ4b from the circuit ASRb of the winding, which is included in the automatic start switch ASRb. Once this switch ASRb has measured its timing time, the latch magnet PMb is turned on by the circuit including the tips ASR2b and causes a forward shift to move the plate down. After closing and locking, the hi88ikori ,, bM leaves downwards towards the third floor and responds to all calls from the floor levels downwards in the traffic it encounters along the way.

At the moment when the upper non-conductive part of the controller HCBb comes into contact with the hook switch HCC3b in preparation for a stop at the third layer height, the voltage at the cathode 3Cb is no longer applied to the XLGb control gate. This opens the switch LGb and opens the tips LGlb while opening the 17 57576 switch LJb. The contacts LJ3b close, supplying current to the winding of the switch LRb, this switch becoming self-sustaining by means of a circuit including its own contact tips LR1b, contact tips DGDlb, forward transfer brush ZGD2b and MLGZ5 (not shown but corresponding to contact MLGZme, HR and LR in the respective circuits). The contact tips MLGZ5 close because the car "a" is currently located in the main floor, ie street level zone. The switch LRb from the switch defining and changing the direction of the elevator car must remain on until the elevator car "b" stops so that the contact tips LR2b can be kept closed in the winding circuit associated with the switch LGb until the contacts RUN3b and D4b close switch DGb on to start the journey to the uppermost zone, which is now unoccupied for any elevator. However, if now the elevator car was not located on the main floor, i.e. the street level floor, such a change of direction would not take place, because the tips MLGZ5 would be open and the relay LRb would not work. This would allow the elevator car "b" to continue moving downwards towards the main level floor, thus bringing the elevator car here to the main level for future passenger needs.

In any case, the elevator zone center zone switch MZc of the elevator car "c" is in its on state and holds the tips MZ2c open within the winding MZb (not shown but corresponding to the winding MZa in Fig. 3) to prevent the elevator car "b" center zone switch MZb from operating. This prevents the autostart relay ASRb from remaining on after its own time delay, after which the tips NT3 open and cause the elevator car "b" to move away from the middle zone.

In addition to the elevator car not assigned to the zone being automatically returned to the main floor zone where there is no elevator, an invitation from the main floor floor level to the elevator car in the adjacent occupied zone moves down to the unoccupied main floor zone. Detachable tips MLGZ2 in the lower layer call, i.e., LH contacts, between the first and second layer levels (i.e., between the bottom layer zone and the middle zone) and detachable tips from the MLGZ1 and IFGZ2 circuits in the LH contacts of the fourth and fifth layers. between the uppermost zone) form a circuit for the main level floor call from the end of the XLJ tube circuit to an elevator car in an adjacent occupied zone, as a result of which this elevator car moves downward. This brings the elevator car for passengers who want it to the main floor level without them having to wait for the return of an unnamed elevator car to any zone. In addition, they open when the main floor level is unoccupied by the contact tips f · ,. - 18 57576 MLGU coil in FLC circuit included in false call switch. The winding FLC now no longer receives power when the charge in its timing circuit is lost and then the false call switch opens to close the contacts FLC1 from the primary service circuit to place an indication of the call via the contacts MLGZ2 to the tips LH2. This causes the elevator car in the adjacent reserved zone to arrive at the level of the main floor, which is thus primarily served. In contrast to the operation on the other floors, when the elevator car arrives at the main floor, it always opens its doors, even if it does not currently operate on the basis of the recorded call. This is due to the fact that the tips of the MLZU are attached to the winding circuit associated with the call pickup relay CPR assigned against it as this elevator car approaches this floor level.

From the above explanation, it can be seen that while calls are periodically recorded, an elevator car coming to a zone that does not have a designated elevator car in that zone is designated "elevator car for that zone and prevents any call from that zone from the floor level. no other elevator car for this zone.The elevator car for a particular zone operates on the basis of all floor level invitations issued from its zone.It stops as it moves upward to those floors where commands are recorded from its own elevator car buttons and also to floors where calls up are stored inside. stops the car of a particular zone as a result of commands given from its own car and orders from floor-level down to traffic In circumstances where a call from the floor-level in a given zone is reversed If the elevator car in this zone has the last floor level call in this zone and the car does not operate on the basis of any other command given behind such a reverse call, the car in this zone also stops on the basis of such a floor call in the opposite direction. The stops are performed in the natural order in which the floor levels are reached, regardless of the order in which these orders are recorded. An elevator car assigned to a particular zone moves out of its zone only on the basis of a call recorded from the elevator car, or acts in response to a floor-level call issued from the floor level of its own zone, provided that subsequent zones adjacent to its own zone also designated elevator cars. Under such conditions, this designated elevator car stops at the floor level in its own zone if no calls have been made. If the zone above which this elevator car is assigned does not have any elevator car designated therein, this designated elevator car may move from its already designated zone in response to calls from floor levels in such a zone above. The elevator car of a certain zone also leaves its zone to move to the unoccupied main floor level from the adjacent occupied zone if a call from the main floor level from the floor level buttons is recorded or if the main floor level zone has been without the elevator car for a certain predetermined time.

When the elevator car leaves its own zone, the elevator car loses its designation to a specific zone, i.e. the task is set as an elevator car in this zone, and it works for all floor level calls in the direction it is moving and also works for all other commands from the elevator car. memory. After the elevator car has lost its designation as an elevator car for a particular zone when it enters an already occupied zone that is not a main floor level zone, it continues to move in response to any calls it may encounter in the direction of its movement. An elevator car that enters the main floor level, i.e., the ground floor zone, causes the elevator car that may be present in the ground floor zone while its MG device is running to leave the main floor level and move up as an unnamed elevator car. If the MG device of the existing elevator car is not running in the main floor level zone, the incoming elevator car is then forced to exit and go up again to any zone as an unnamed elevator car, now acting on all calls it may encounter in the direction of its movement until it reaches the zone. which is not designated, in which case it shall be designated for this zone. If it no longer has to act on a memorized command, it stops and waits in its zone for a certain layer. A particular selected elevator car at the main floor level is caused to exit the main floor level, a command given from the elevator car is recorded therein, or when a call from the floor floor is recorded in an adjacent zone that is not assigned to any elevator.

The arrangement now described can also be used to handle traffic conditions that differ from those in which traffic calls are memorized periodically. For example, it can be assumed that the system is equipped with any of the devices for measuring downward traffic, such as are already known per se. Such a device may be either a switch similar to the continuous call switch CC operating at a predetermined number of floor level traffic calls recorded during a predetermined period of time, or it may be a load-weighing switch operating at a predetermined load in a downward-moving elevator car or elevator cars. It can further be assumed that ** »· ·· v.

20 57576 the downward traffic is sufficiently increased »as a result of which the traffic measuring device comes into operation and supplies electric current to the winding contained in the downward traffic relay (not shown). As a result, all the closing pairs of tips in this relay become closed and all the pairs of opening tips diverge from each other. A pair of closing contacts in the downlink relay connected via line L10 to one of the drive windings GÖD of this group (Fig. 4) keeps this switch in its on position as long as the downlink relay remains on. In addition, the pair of opening contacts in this downlink relay connected in series between each of the respective ZRB4 selection contacts and the pair of closing contacts in the top zone relay TGZ (corresponding to .operating · which would reverse unnamed elevator cars. movement as they move upwards until they reach at least the lowest stratum level in the area of the uppermost zone.

Under these conditions, the continuous operation of the group upward transmitting switch GRD causes all elevator cars that are stopped or then stop at the height of the main floor level, i.e. the ground floor, to be transmitted from there upwards, as previously described in the case of elevator car "c". As they move up, each of these elevator cars retrieves a zone unnamed for any elevator car, i.e. a zone that does not currently have any elevator car designated there. This is carried out in the same way as previously described for the elevator car "b" and "c". Thus, as they move, each of these elevator cars responds to instructions given from its own elevator car to any uplink call that this elevator car encounters from the floor level. As mentioned, all elevator cars not designated for any zone are prevented from changing their direction of movement as they move up until they reach at least the lowest floor level of the upper zone, despite the fact that no call is recorded above these elevator cars. Changes in direction that might otherwise occur are prevented because the spaced-apart contact tips are detached in the downlink traffic relay when connected in series with the corresponding selector tips ZBB4. Upon arrival in the top zone, all car lifts, whether assigned or not, respond to all calls from their own car car and any calls from upstairs to the traffic they encounter and are now allowed to change direction at the top floor level for the order, provided no lift or call up from the floor level does not exist above it. This change in direction 21 57576 occurs in the same manner as previously described for responding to downlink traffic calls from floor levels when describing the operation of elevator car "b" due to a sixth floor call.

If no call from the elevator car or floor level is recorded in any part of the floor level in the area of the uppermost zone when the elevator cars arrive there and another elevator car is already assigned there, the elevator car enters its uppermost endpoint before changing its direction of movement. the reversing switch HRa, etc. is not provided until the corresponding top-level switches TLZa, etc. of the zone are turned on. By reversing the direction of movement, these elevator cars are moved from the top zone to any zone as unnamed elevator cars and travel down to respond to commands from their own elevator car and to any downstream traffic orders they may encounter.

The elevator cars that will be designated for the middle and upper zones »operate in these conditions in the same way as previously described. Thus, even if the elevator car is designated for the middle zone until it begins to perform a downward movement and is required to move downward on the basis of a call from below, it is free to provide services to passengers in the upper zone if there is no elevator car in the upper zone. This is carried out in the same way as previously described in connection with the elevator car "b". Accordingly, it should be understood that the present invention is capable of providing an increased service to passengers who wish to travel downward using a downward traffic measuring device whenever downward traffic reaches a predetermined situation and using this device when first acting to prevent stagnant or perhaps they then have to stop on the ground floor from staying here in the ground floor zone, as they would otherwise do if they did not record the calls they may answer and secondly prevent upward moving unnamed elevator cars from changing direction before they enter the top zone.

Suppose now that the number of elevator cars moving upwardly from the ground floor with the base car elevator call relay LCCR on is more than a certain predetermined number of the number of elevator cars on the ground floor. For example, suppose that in this system, the elevator cars "b" and "c" are moving upwards from the ground floor. Let us further assume that when each of them left this layer level, it either had a sufficient load, that the contact tips NS2b and NS2c (not shown but similar to the tips NS2a in Fig. 8) close, or that they were pre-determined the number of invitations given from the elevator car. In either case, a predetermined amount of a transmission signal is provided as it passes in the second case through the contact tips NS2b and NS2c and in the second case along the conductors ZCb and ZCo (not shown but similar to the conductor ZCa in Fig. 8). Such a signal passes through the sener diode Z2 »whereby the associated silicon rectifier SCRb and SCRc (not shown but similar to the rectifier SCRa in Fig. 8) begin to conduct. In this way, the relays LCCRb and LCCRc are used (the winding circuits are not shown, but are similar to the winding circuit of the relay LCCRa in Fig. 8), as a result of which the tips LCCRlb and LCCRlc close and these relays also become self-supporting by circuits including DGU7b and DGU7c (not shown but similar to the circuit including the tips LCCRla and DGU7a). These circuits remain closed as long as the corresponding elevators continue their upward movement. Likewise, the tips LCCR2b and LCCRc thus open, removing two parallel current paths on the upper voltage side from the main layer zone bridge bridge circuit, the bridge diagonal portion of which includes the winding of the first auxiliary main layer zone relay XZLP (Fig. 8).

It is now assumed that at this point in time the elevator car "a" is located and assigned to the uppermost zone and that it is stopped on the floor level there with its doors closed and that there is no other need for its services e: L. As a result, no elevator car is at the ground floor level and that the elevator car locating relay CMLZ in the floor floor zone of each elevator car is open (the winding relay CMLZa for the elevator car "a" is shown in Fig. 7 and others are not shown but are similar). The contact tips CMLZa, CMLZlb and CMLZlc (Fig. 8) are therefore all closed on the low voltage side of the bridge circuit requirements of the above-mentioned main floor level zone, and the first auxiliary main floor zone zone demand relay XZLP is used to indicate the ground floor This closes the contact tips XZLP2 (Fig. 8), thus supplying current to the winding of the relay ZLPX of the second auxiliary main layer level zone, which then acts to close the tips ZLPX1 (Fig. 8). As a result, the main floor level zone ordering relay ZLP works, closing the tips ZLP4 (Fig. 5) · This together with the closed tips CMLZ2a signals the \ «/ 23 57576 for winding. As a result, the elevator car "a" moves downwards towards the ground floor. At the same time, the peaks ZLP3 open (Fig. II) and open the priority zone relay XZP of the auxiliary zone. As a result, the XZP1 tips (Fig. 7) thus close, in turn closing the circuit zone to the winding of the priority relay ZPRa, this being done via the closed tips XD07a, GH3a, RUN5a and PMY7a. The relay ZPRa becomes self-supporting by means of its own tips ZPR4a and the circuit passing through the touched DGU8a, LG2a and XZF1. As the elevator car "a" moves down, the open contacts ZPR2a (Fig. 6) prevent it from answering any floor-level call down to any traffic it may encounter. When no commands from the elevator car have been recorded in it, the elevator car travels non-stop to the ground floor to then be ready to handle the expected need for heavy traffic there.

Suppose now that the arrival of the elevator car "a" down does not balance the bridge circuit of the traffic demand in the ground floor zone. As a result, relay ZLP still remains on. The open contacts ZLP3 of the relay ZLP keep the relay XZP open. As long as the relay ZLP is retracted, the elevator car "a" will remain at the height of the ground floor until the above command from the elevator car causes it to start, because the automatic start relay ASRa (Fig. 2) remains energized, with closed-ended MLU5a, HJ7 and HZP 3. Under these conditions, the upcoming floor level call does not move the elevator car "a" because the contacts ZLP2 (Fig. 6) remain separated from each other in the HHa contact circuit and thus prevent the relay HJXa from receiving current due to such a call.

While relay XZP remains open, the zone priority relays ZPRb and ZPRc (winding circuits are not shown, but are similar to the relay ZPRa circuit in Figure 7) operate through circuits including closed tips XZP2 and LCCRjJb and XCRP, respectively. c (not shown, but similar to the corresponding circuit for the elevator car Ma "including contacts XZP1 and LCCRJa).

As a result, the circuits for elevator cars "b" and "c", which include the tips ZPR1b, ZPR2b, ZPRlc and ZPR2c (Fig. 6), also allow these elevator cars "b" and "c" to bypass calls from different floor levels, stopping only the elevator car commands. This situation continues as long as the relay XZP is switched on, and as long as the relays LCCRb and LCCRc are in operation, their tips LCCR4b and LCCR4c are open in the HJX circuits for the elevator cars "b" and "c" (Fig. 6) and again, these elevator cars travel only as high as their respective top command from the elevator car, reversing their direction of movement at the height of these command layers and descending as a result of the characters provided in the memory of the call circuit CMLZ2b and ZL of the elevator car CMLZ2b and ZL and ZLP9 (not shown but similar to the circuit passing through the tips CMLZ2a and ZLP4 for the elevator car "a" as shown in Fig. 5). The change of direction is carried out at the command of the top elevator car by closing the circuit from the top call relay HR (Fig. 5) through the tips PMY6, RUN1, HJ3, DGU1 and the relevant ZLP relay or possibly through the relevant middle or top zone switch tips. The relay HR must keep on while stopping for this motion command until the return coil of the direction-maintaining switch DG (Fig. 2) receives current through the contact tips HR1 and CFR1.

When the direction of movement of either of these elevator cars changes, the order bridge of the ground floor zone is balanced if the elevator car "a" is still located on the ground floor, because there are now two parallel paths provided for each branch of the bridge. On the higher voltage side, these two paths are provided by the elevator car "a" and the elevator car whose direction of movement changed via the contacts LCCR2. On the low voltage side, these two current paths are provided through the elevator car contacts "h" and "c" CMLZ1, with both elevator cars located above the ground floor. This relay opens after the time delay caused by the resistor and capacitor circuit ZLPXQ connected in parallel with it. In this case, the relay XZP has to be switched on, returning the elevator.

It should now be noted that the operating and opening conditions for the XZLP relay are optional elements of the structure and that the conditions described above may not be applicable to all buildings or all traffic situations. When the embodiment of the relay XZLP shown is described, it comes into operation when the number of upwardly moving elevator cars with their LCCR relays on exceeds the number of elevator cars that are blown. the number of lifts in the upstairs lift with their LCCR relays on is equal to the number of lifts in the ground floor which may be made more desirable by the special traffic conditions found in a particular building and the opening of the relay XZLP as a result of some other conditions.

25 57576

As has already been described, the elevator car does not start moving upwards at the level of the ground floor during a high traffic period unless a command from the elevator car is recorded in it. This can easily be changed so that the selected elevator car on the ground floor starts moving as a result of either an order from the elevator car or a call from the floor level in the adjacent zone to which no elevator car is assigned. Such a change can be easily implemented by short-circuiting the tips of the ZLP2 contact HH circuit (Fig. 6) so that the selected elevator car can operate on the basis of such higher floor calls.

Turning now to the operation of the upper zone paging circuits, it is to be understood that the floor level calls memorized from the middle zone provide a token whose magnitude indicates in this zone the 9. How many of these circuits receive this signal depends on the magnitude of this signal, for example, as shown here, the magnitude of the current in conductor ZM may be the result of two calls from the middle zone layer level passing through zeener diodes Z3 and Z4 and introduced into circuits including transistors T1Q, T2q, T5q.

Based on the memorization of the four layer-level calls recorded from the middle zone, current flows through the zeener diodes Z3-Z6 and this current is applied to the circuits including transistors T1, T2 and T5 as well as to the already mentioned circuit. If five calls from the layer level from the middle zone are recorded, the signal passes through the zeener diodes Z3-Z7 and is applied to all three of the multi-unit circuits.

The phenomenon which is introduced into the system on the basis of the magnitude of the call signal from the floor levels of the middle zone, this signal passing along the conductor ZM, can be adjusted by the number of elevator cars located in this zone. Thus, although the signal along the conductor ZM indicates the recording of the two layer-level calls, the magnitude in the middle zone is sufficient to pass through the zener diodes Z3 and Z4 and to cause the transistors T1 and T2 to operate, if no signal is received along the conductor. transistor T3o from being conductive. Such a signal is obtained if any elevator is located in the middle zone. This, in turn, occurs as a result of one or more of the contact tips CMZlb and CMZlc being closed and the subsequent passage of a signal through them, which * V · ‘‘ 26 57576 sign is large enough to pass through the zener diode Z8. Under these conditions, the transistor T1 conducts and the conductor I is practically Λ at the same voltage as BO, which prevents the transistor T30 from being conductive. Similarly, the location of two or more elevator cars in the middle zone provides a signal large enough to pass through the zener diodes Z8 and Z9, thus causing the transistor T2 to enter the conductive state. As a result, the conductor II is practically energized at BO and this prevents the transistor T3 ^ from entering the conducting state despite the fact that the transistors T1 ^ T2 ^ have operated as a result of simultaneously memorizing four or more layer-level calls from the middle zone. Similarly, the location of the three elevator cars in the middle zone places the conductor III substantially at point BO voltage and prevents transistor T32 from being conductive, although five calls from the floor planes may be simultaneously recorded from the middle zone.

Assume now that four calls from floor levels are recorded in the middle zone and that only the elevator car "c" is located in this zone, the elevator car "b" is located in the ground floor zone and the elevator car "a" is located in the uppermost zone. and that there is no other need for their services at that time. Under these conditions, the center zone elevator car locating relay CMZc, (the winding circuit is not shown, but is similar to the elevator car circuit "a" shown in Fig. 7) occurs as a result of the brush TCBc coming into contact with one of the contacts ICC2c-ICCkc. The tips CM ^ Ic (Fig. 9) are closed, moving the signal through the zener diode Z8, which causes the transistor T1 ^ to enter the conductor state. This signal is not large enough to pass through the zener diode Z9 and as a result is prevented from entering the base of the transistor T2. This transistor is therefore non-conductive and the mark on conductor II is at the voltage at point B +.

The four calls from the layer levels in the middle zone provide a signal of sufficient magnitude to pass through the zener diodes Z3, Zh, Z5, and Z6 (Fig. 9). As a result of this signal, the transistor T1 ^ becomes conductive, which in turn makes the transistor T2 ^ in a non-conductive state. The collector voltage of the transistor T2 in its non-conducting state and the voltage in the conductor II allow the transistor T3 to be in the conducting state. This, in turn, moves the transistor T3 ^, the collector, to virtually the point BO, which causes the transistor TU to conduct. As a result, a signal is applied to the control electrode of the SCRM of the adjusted silicon rectifier, which causes it to conduct the voltage in the conductor AC1 during the positive 27,57576 half-cycles. The flow of electricity through the rectifier SCRM places the auxiliary middle zone order on top of the relay ZMPX coil, thus using this relay and closing the tips ZMPX1 (Fig. 8). This in turn uses the ZMP middle order relay.

As a result, the tips ZMPi + (Fig. 5) close, introducing a signal via the closed tips CMLZ2a to the elevator car call circuit in the elevator car "a", which function corresponds to the command given to the fourth floor from the elevator car to turn on the relay LGa. As a result, the elevator car "a" is made to travel downward toward the fourth floor level after the time delay included in the automatic start relay ASRa has elapsed (Fig. 2).

The operation of the middle zone ordering relay ZMP also opens the tips in the ZH2 contacts HH circuit (Fig. 6), preventing the elevator car in the middle zone from answering calls from the top when the zone is now empty.

"Contacts ZMP3 (Fig. 11) also open. This disconnects the upper zone priority relay HZP from the winding of the circuit, causing it to open and opening its tips HZP1 (Fig. 11). As a result, the auxiliary zone priority relay XZP opens and closes its tip XZP This closes the circuit via the terminals XD07a »öH3a, RUN5a and PMY7a to the winding of the zone priority relay ZPRa for the elevator car" a "even before the time delay of the automatic start relay ASRa expires.

The current in the zone priority relay ZPRa winding can cause this. On the relay by closing the self-holding tips ZPRi and opening the tips ZPR1a and ZPR2a. The opening of the latter two tips prevents the elevator car "a" from responding to calls from the floor levels while still acting in response to the signals given to the command circuits in its elevator car via the contacts ZMPk. In this way, those elevator cars moving to the upper zone in response to a busy traffic request indicated by the operation of the associated subscription demand relay ZTP or ZMP are prevented from stopping in response to calls from floor levels on those floors where such calls might otherwise be encountered.

As the elevator car "a" enters the middle zone, its ridge LHBa (Fig. 6) comes into contact with the contacts LH 2 and any call ordered from the fourth floor floor level or any up or down traffic call from any floor in the middle zone below this fourth floor level space and. to make the lower layer call switch LJXa current. This activates the switch by closing the tips UX1a and keeps the lower call switch Ua (Fig. 3) still on. As a result, the contacts U3a (Fig. 3) remain open 28 57576, preventing the lowest call rotary switch LRa from operating and the elevator car maintaining its downward direction of movement.

At the same time as the elevator car "a" enters the middle zone, it brings the brush ICBa (Fig. 7) into contact with the tip ICCU. This supplies power to the windings of the center zone elevator car locating relay CMZa and the relay operates by closing its tip CMZ1a (Fig. 9). This increases the signal strength through the zener diode Z8 enough that it can also pass through the zener diode Z9. As a result, the transistor T2 ^ conducts current and virtually applies a voltage at BO to line II. As a result, the transistor T3 ^ enters the non-conducting state, removing the voltage at BO with respect to the transistor Tt ^, whereby this also enters the non-conducting state. This removes the gate signal from the rectifier SCRM and stops conducting current when the positive half-wave of the voltage on its anode circuit falls below the voltage necessary to maintain the conduction state. As a result, the auxiliary middle zone ordering relay ZMPX opens, opening its own tips ZMPX1 (Fig. 8). This in turn opens the auxiliary middle zone subscription demand relay ZMP, indicating the end of a heavy traffic demand in the middle zone. This closes the tips ZMP2 (Fig. 6), allowing the elevator car from the middle zone to follow calls from the top zone if there is no elevator car assigned to it in this zone. The contacts ZMPU (Fig. 5) open, removing the mark introduced on the HCCU tips of the elevator car "a". Thus, the lower call switch LGa of the call from the elevator car opens when the positive half-wave of the voltage applied to the anode plate circuit of the tube XLGa falls below the value of the voltage necessary to maintain the wire state. Opening the switch LGa opens the tips LG2a (Fig. J), thus disconnecting the self-holding circuit from the zone priority relay ZPRa, releasing this relay, which closes the tips ZPR1a and ZPR2a. The elevator car "a" is therefore able to follow the calls given from the floor levels.

The opening of the middle zone order relay ZMP (Fig. 8) also closes the tips ZMP3 (Fig. 11), thus supplying current to the HZP winding of the upper zone priority relay. This causes the relay to operate, thus closing its tips HZP1 (Fig. 11) and supplying current to the winding of the auxiliary zone priority relay XZP, which in turn acts to separate the tips XZP1 (Fig. 7) within the zone priority relay ZPRa .. Of course also the tips XZP2 and (not shown but corresponding to tips XZP1) in the circuits of the zone priority relay windings for the elevator cars "b" and "c", the open zone priority relays ZPRb and ZPRe open, if either of them was in operation.

As the elevator car "a" moves downward in the middle zone, it is prevented from being assigned to it as long as the elevator car "c", which is already assigned to this zone, remains there. This is because the tips MZlc in the middle zone switch MZa within its winding circuit are detached. However, if the elevator car "h" remains in its assumed position on the ground floor, the tips MLGZ3 (Fig. 3) remain closed and if no call from the elevator car is recorded in the elevator "a", as a result of which it would move down from the middle zone only so far than what is required by its service from the lowest elevator car or floor level call when these floor levels join that zone. When this call is removed, the circuit of the lowest call turn switch LRa (Fig. 3) is simultaneously provided to the windings of contacts PMY5a, RUN2a, LJ3a, DGDla, brush ZRBa, intermediate switch ZRCa at the layer level where the call was marked and via contacts DGDa3 and DGD3 This winding is kept energized through the contacts Ulla and CPR4a, the fixed elevator car stops to allow the winding of the winding of the directional switch DGa (Fig. 2) to be done when this occurs via the contacts RTJföa, LR2a, U4a and D4a. This, in turn, uses the switch DGa, placing it in the position on it and reversing the direction of movement of the elevator car and determining the direction of subsequent movement upwards. After the elevator car "a" has stopped and closed its door again, it then moves upward in response to calls like any elevator car in a particular zone to which it is not assigned, until it returns to the uppermost zone to which it is again assigned.

Instead of the elevator car "h" remaining in the zone of the ground floor, it could have started moving from there. However, this could only happen as a result of an order for an elevator car. Assigning the elevator car Mc "to the middle zone keeps the MGZ1 tips detached within the HH contact circuit (Fig. 6) preventing the elevator" h "from answering a floor level call coming from above the ground floor zone, and naming the elevator car" b "and its position in the ground floor zone -Mia CMLZ2b and CAZ1b (not shown, but corresponding to those touched CMLZ2a and CAZ1a in Fig. 5) separately, preventing the signal from entering the elevator "bM elevator car call circuits as a result of the busy ordering requirement in the middle zone.

Assuming now that the elevator car -b- had moved out of the ground floor zone, the tips MLGZ3 (Fig. 3) would have opened when the elevator car "a" moved down again in the middle zone and instead of changing its direction at the lowest call there it would have continued to move down. zone to be assigned. It must now be seen that if the elevator car "b" leaves the ground floor in such a state that enough calls from the elevator car are marked in it '· * • i- 50 5 7576 memory so that the relay LCCRb (the winding circuit is not shown but corresponds to the relay LCCRa in the figure) 7 circuit) would pull while the busy traffic situation in the middle zone still exists it bypasses the calls made from the floor levels. Contacts XZP2 (not shown but corresponding to contacts XZP1 in Fig. 7) turn on because the need for heavy traffic in the middle zone still exists and because the zone priority relay ZPRh (the winding circuit is not shown but corresponds to the windings of relay ZPRa in Fig. 7). ) is operational, receiving current through the contacts LCCRJb (not shown, but corresponding to the contacts LCCR in Fig. 7).

In the above, it was assumed that the arrival of elevator "a" in the middle zone in response to heavy traffic there was sufficient to cause the relay ZMP of the middle zone orders to open. Assume now that the recorded calls are such that transistor T3g (Fig. 9) is conductive when the elevator "a" enters the middle zone and that as a result the relay ZMP of the middle zone orders does not open even if such an entry occurs. (Fig. 3) closed and allow the elevator "a" to change direction at the lowest and highest call in the middle zone, despite the fact that the elevator car may not have been assigned to the ground floor zone or the upper zone.

It should now be noted that the middle and upper zone ordering relays for the windings ZMP and ZTP (Fig. 8) form a priority arrangement that prevents the middle zone ordering relay ZMP from turning on if there is a need for heavy traffic in both the middle and upper zones. , so that the auxiliary order relays ZMPX and ZTPX for both of these zones are on. In some cases, it may be more desirable not to provide any priority possibility and this can be easily accomplished by shorting the contacts ZTP1 from the ZMP winding circuit of the middle zone ordering relay. If this procedure causes the need for heavy traffic in both the upper and middle zones, the upward moving car bodies move to the uppermost zone as a result of the signals brought to their respective HCC5 tips (Fig. 5), and · HCC4 contacts (fig.

5). Thus, under these conditions, neither of these zones of high traffic demand will receive any priority.

When a high traffic demand arises in only one of the upper zones, it can be seen that the car lifts in this zone are prevented from operating.% *,% · · * · “* 31 57576 based on floor level calls recorded from the zones above this zone for the reason that the order relay associated with the zone opens the tips from the circuit including the contacts HH (Fig. 6).

However, any elevator car in this zone can respond to a floor level call from the ground floor by the tips MLGZ and MGZ in this LH contact circuit (Fig. 6) provided that no elevator car is located in the ground floor zone and no elevator car is located closer to the floor level is that layer in the high traffic order zone located closest to the ground floor.

Although the invention has now been described as being applied to a system without elevator operators, i.e. to "self-service elevators", it can be applied to systems arranged to operate only with elevator drivers or to systems arranged to operate either by elevator drivers or as self-service elevators. Similarly, although the installation of three elevator cars and seven floors has been described, it should now be noted that the invention is applicable to installations with a different number of elevator cars and a different number of floor levels, including one or more basement floors. In the case of cases with one or more basement floors, the basement layers can be considered as floor levels within the ground floor zone and are therefore served by an elevator car in the ground floor, i.e. the main floor zone. Invitations from the floor levels on which the elevator cars operate may vary. For example, although it has been described that an elevator car not designated anywhere in a reserved zone responds to calls made at floor levels from an already designated zone in its own direction of travel, it may be arranged that such an elevator car not designated for the zone does not operate on such calls.
