Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator control device, and more particularly to a control device suitable for an elevator operation control sequence circuit.

Conventionally, in general sequence control, the diatance is composed of wired logic, so the sequence itself is hardware, which directly affects cost and reliability. Therefore, the important point when creating this sequence was to configure it with the minimum number of relays and even the minimum number of contacts. This also meant that the highest priority was placed on minimizing the hardware costs required for sequence control. As a result, sequences created in this way are far from being easy to create and maintainable, and have the disadvantage that the control functions of the sequence cannot be understood without the operation WiH document. This has caused the problem that a thetance defect is found after ms.

On the other hand, there is a similar problem in elevator control, but in this case, the operating method and operation of the elevator does not greatly contribute to each customer, so using the technical know-how accumulated over many years, It was possible to create a sequence using the method described above. However, it has the disadvantage that it takes a lot of time to confirm when new functions are incorporated, and it takes a lot of time to train new designers and inspectors.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control device in which the sequence is easy to set up and functions can be easily changed or added.

In order to achieve this object, the present invention enables an elevator control device to select an operation method from among a plurality of operation methods in response to an information input signal regarding the operation method, and to operate the elevator according to the selected operation method. A driving method control device that outputs driving action commands for switching operating conditions, and a driving method control device that outputs driving action commands that change the operating conditions, and a driving method control device that outputs driving action commands that change the operating conditions;
It is characterized in that it is composed of a plurality of operation control devices that control the operation of the C elevator.

The invention will now be explained to the calling party with reference to the illustrated embodiment.

#s1 is a block diagram showing a schematic configuration of an elevator control device according to the present invention.

In this figure, reference numeral 1 denotes an elevator operation method control circuit, which is composed of an operation method selection circuit 2 and an operation command circuit 3. 4 is an elevator operation control circuit, which combines the operation control function of the elevator operation control circuit in wired logic using conventional relays with a door opening/closing control function;
It is roughly divided into a car call control function, a control completion control function, a speed abnormality detection control function, etc., and is composed of n- base operation circuits 4a to 4n provided corresponding to each of these functions.

Among the elevator input/output signals consisting of several points, dozens of operation method instructions from the operation panel and monitoring l111a, etc. related to the basic functions of the elevator operating conditions (the functions of the basic operation circuit described above). The long sword signal 0PINF is input to the operation method selection circuit 2, and most of the other input/output signals are not particularly shown (.are directly connected to each basic operation circuit 4a to 4).
connected to n.

The elevator control status signal ST is a failure detection signal of the elevator control system output from the elevator operation control circuit 4, a signal indicating the elevator is stopped, the return to a specific floor level is completed, etc. These are also input to the driving method selection circuit 2.

Therefore, operation command signals 81 to 864 instructing the operation conditions corresponding to the operation method code OP CI selected by the operation method selection circuit 2 are outputted from the operation command circuit 3.
The elevator operation control circuit 4 comprising a plurality of basic operation circuits 4α to 4n controls the operation of the elevator under the operating conditions instructed by the operation command signals 81 to 864.

In this way, by organizing the control sequences vertically in a so-called hierarchical structure, that is, in a top-down manner according to the operation method, each basic operation circuit 4 in the horizontal direction on the same level
The relationship between the 4 and 4 elements can be reduced and the coupling can be made more coarse than in the past. In particular, we have worked hard to eliminate the signals related to the operation method instruction signal 0PINF and the control status signal ST, which are a combination of complicated contacts and are scattered in the middle of the basic operation circuits 4α to 4F&, and to improve the operating conditions. Clear operation instruction signal S
1 to 864 can be replaced with one normally open contact or one normally closed contact.

In addition, when adding a new operation method or changing the conditions of an existing operation method, it is necessary to use the functions that any of the basic operating circuits 4a to 4 already have as standard, or the functions that can be used in combination. If so, it is only necessary to correct the operation method control circuit 1 consisting of the operation command circuit 3 and the operation method selection circuit 2.

Furthermore, by checking the operation method code 0PCD when adjusting, inspecting, and maintaining the elevator and when an error occurs,
In addition to immediately grasping the current status of the sequence, you can also grasp the outline of the sequence operation in the 44-wheel transfer system just by looking at the operation instruction specification apple of the operation command circuit 3 and the operation method code 0PCD, so the sequence is much faster than before. This makes it easier to read, improving work efficiency in inspections, maintenance, etc., reducing the incidence of sequence failures, and shortening the recovery time when a failure occurs. This effect is particularly important when a sequence is constructed using a semiconductor circuit such as a microcomputer. In other words, in the past, the current status of the sequence could be grasped by relay operation, but
When semiconductors are used, the sequence cannot be understood unless some means such as a display or printer is provided. In addition, displaying hundreds of sequence signals using LEDs not only costs money, but also reduces inspection efficiency since the number of signals is too large. Therefore, this effect is important because it is necessary to manually enter the address of the sequence signal and check the contents.

FIG. 2 shows an example of the configuration of the driving method selection circuit 2.

The driving method selection circuit 2 is a driving information control circuit 2a.

It is composed of a priority relationship determination circuit 2h and an operation method output circuit 2C.

Signals that require special processing among the driving method instruction signal 0PINF and the control state signal ST are input to the driving information control circuit 2α, where the information is stored, restricted, temporarily held, etc. Output information No. 16 0PST.

In the priority relationship determination circuit 2b, among the designation information signal OP S 1' specifying these driving methods, the driving method instruction signal 0PINF and the control state signal ST that are directly input,
Forge also selects the designated information signal with a high priority and outputs it as the driving method selection signal 0PCDI.

In general, an operating method with a high degree of operational restriction is selected preferentially and controlled to maintain elevator safety.

In the operation method output circuit 2C, the operation method selection signal 0PCL
11 is the operation method defined for the actually delivered elevator or not using the operation method output permission spec 0PC1)
The determination is made based on E, and if permission is granted, this is output as the driving method signal 0PCD. In addition, if the driving method is not permitted, suspension 1 due to selecting an undefined driving method.
The operation mode is output as the hail 1 signal 00 (see Fig. 4) as the operation mode signal 0PCD.

FIG. 3 shows an example of the configuration of the operation command circuit 3.

The operation command circuit 3 includes an operation command selection circuit 3x and mantissa operation command output circuits 3α to 3f.

The operation command selection circuit 3x selects the operation command SIA, etc. corresponding to the operation method signal 0PCD from the operation command specification opspc.
Select from among them to output.

Here, the relationship between the operation method and the operation command signal is shown in Figure @45. The operation command signal 5IA-84OA is "1" and "0"#j
It is a built-in signal, and is sent directly to the elevator operation control circuit 4.
It is possible to use it for Therefore, the operation command output circuit 3α simply takes and outputs the operation command signal specification 0PSPCE necessary for elevator control at the customer's destination.1 In contrast, the operation method classification signal command 5ICD, elevator door Conditions for automatic door closing time (conditions for the door to start closing when the idle time is 0 seconds, conditions for the door to start closing in 2 seconds for car call service, 3.5 seconds for hall call service, 5 seconds for standard floors, etc.) Automatic door closing command DR1
'C1), Speed command VCD that commands the maximum operating speed
, a specific floor command FLHCD, which is a command to wait or call to a specific floor.

The failure detection command TCD etc. that commands the range of failure detection is pure 2.
Encode it into a base number etc. and output it. Therefore, the operation command output circuits 3b to 3f change to signals that are easy to use in the elevator operation control circuit 4, such as coded command signals.

FIG. 5 shows the functions of the operation command output circuit 3b.
It is an explanatory diagram, and the driving method classification signal command 5ICD is ()0.
At 0 o'clock, no operation command is output.

Further, FIG. 6 is an explanatory diagram showing an example of the function of the operation command output circuit 3e, and the actual floor name and specification are specified according to the conditions and specifications of the building in which the elevator is installed in response to the specific floor command PL) LCD. Floor signal 5FLNO is defined.

The embodiments of the present invention have been described above, but in order to make the present invention more specific, an example will be given in which a microcomputer (hereinafter referred to as a microcomputer) is used as a sequence control circuit. This will be explained below.

Figure 7 shows a program P that starts processing as soon as the power is turned on.
It is a flowchart of GM1.

The initialization program M 100 sets initial values of the programmable LSI constituting the microcomputer and initializes the RAM (generally clears all areas to "0"). The stack pointer is also set at the same time. Next step M
The IIO determines whether communication with the group management microcomputer is being performed normally, and if YES, performs data transmission/reception control processing with the group management microcomputer in step M120, and sets the communication link signal MLNK to l'' in step M130. If the determination in step M110 is NO, the communication link signal MLNK is set to "0" in step M140.
Reset to . Next, in step M150, monitor control is performed to display and transmit the sequence status on an LED, CRT, etc. display fFK.

FIG. 8 shows a generic 70-cheat of the machine control program PGM21 that is activated in priority to the program in FIG. 7 by an interrupt that occurs periodically after the execution of step M100 in FIG. 7 is completed. .

In Figure 8, first, the timer control logcum of step M400 is executed, and the sequence program P (3
In M21, the time limit of the timer that is requested to be counted is checked. Next, 1' human power from outside the microcontroller! In step M440, control is performed to input the I number all at once into the microcomputer as 1* information.

Note that the present invention is based on the machine control program PGM shown in FIG.
21, but the explanation will be omitted here, and only programs directly related to the present invention will be explained in FIGS. 9 to 12, which will be described later.

The results of the processing jl of the sequence program PGM21, that is, the control output data, are output all at once in step M690, thereby issuing, for example, lighting of a car response light or commands for controlling door opening/closing.

When the above processing is completed, all the processing of the interrupt program is completed, and the process returns to the repeated processing shown in FIG.

Next, the control processing of the operation method control circuit 1 will be explained in detail with reference to FIGS. 9 and 101.

FIG. 9 shows a part of the driving information control circuit 2α. The power supply establishment soft relay Z97A meets the basic conditions for starting sequence control of the voltage confirmation input signal soft contact PWON1 of the safety control hard relay circuit and the ON timer soft contact ONT that turns on at a certain time after the microcomputer is started. Determine whether or not. Also, when the normal power supply is out of power (NPW, is "θ"), the emergency power supply (MPW, is 1)
'') allows multiple elevators to be moved one by one to one of the standard floors.
Control is performed to cause the first-order return to the floor. In this sequential return control, a return command is input to one elevator, and soft relay contact SSW becomes N111, and soft relay Z9
This is done by turning on 7A.

In addition, after returning photons from all elevators one by one, only the soft relay Z97A of the machine that commanded one elevator to continue (soft contact TSW was set to 1") was ONL, only for that machine. Service operation is now possible,
As shown in FIG. 4, the operation mode of the other elevators is set to power standby (UP(1)=01) by the priority relation determination circuit 2b of the operation mode shown in FIG. 10, and the elevators are completely stopped.

The soft relay SLA is used to prevent the elevator from stopping once when the maintenance operation switch on the switching board is turned ON (soft contact 5LOW, and 5LOW in Figure 410 is '''l'') while the elevator is moving in a erratic state. Soft contact 5peH, is '0'
)do! At 4!0N-1, the operating method signal (JPCL) 1 is set to 0 in step M489 until it becomes still due to m10 diagram (1) soft m point 5 LOW and S LA.
0, select the operation mode of pause 1 as shown in Figure 4,
For example, the first fault detection command "l' CD shown in FIG. 3 is set to oo, so that at least the low speed overspeed lateral ratio is not executed, thereby preventing malfunction detection.

Soft relay) tT is a return detection knot relay that detects returning to a specific floor due to air traffic control or parking commands, and is connected to car position ti6ml, car f CPFNO and % building floor command signal S)"LNO. Soft relay RT is turned ON when Kin is detected, and turned OFF when there is a discrepancy.

The horn r' relay l) t'l' detects the complete completion of the fire, and the soft contact S of the fire control operation command output from the operation command output circuit 3b of FIG. 3 under the conditions shown in FIG.
55. is "1" and the soft contact RT of the return detection soft relay RT is "1", that is, when the fire control is completed, it becomes "1".

Figure 10 shows, in addition to the above-mentioned operation commands, an external signal for safety detection (soft contact 5AFTY,), an internal signal ('I'BB,) for detecting one major failure, and a system for rescuing canned goods without using a microcomputer. An external signal that commands low-speed operation for the purpose of construction operation (MSLOW,), an external signal that commands people's control (FISW,), an internal signal that consolidates medium-level failure detection (TBD,), and a manual operation attached to the operation panel. Manual operation command signal (ATTθ) by switch.

The operation method is selected in the priority order as shown in the circuit by soft relay contact signals such as internal signals (MLNK, ) that detect that communication with the group control microcomputer is normal, and the operation method is selected in steps M482 to M499. Signal 0PC
Create DI. Then, this signal passes through the operation mode output circuit 2c of FIG. 2 and becomes the operation mode number 0PCD, outputting an operation operation command as shown in FIG. 5 to control the operation of the elevator.

Here, in the case of microcomputer control, use the operation command specifications shown in Figures 4 to 6, the operation command fraud specification 0PSPCE used by the operation command output circuit 3α, and the operation method output circuit 2C.
The operation method output W + town spec opcog used in the 2018-2018 can be a group of codes arranged and arranged in a certain order, and the correction of the majority of sequence conditions can be completed just by modifying this, so it is not necessary to modify or Not only is it easy to create a new design, but the outline of the sequence can be grasped from FIG. 5, making the sequence much easier to read.

FIG. 11 shows a specific example of step M605, that is, the door opening/closing control circuit 4a.

In step M101, it is determined whether or not to perform an automatic door closing operation, and either step M102 or step M103 is executed. Step M 10
In step 4, as can be seen from FIG. 4, in the operation mode in which the elevator is stopped or paused, it is detected that both operation commands S1 and 82 are 'θ'', step M105 is executed, and door opening/closing is also stopped. Step M
106 determines the maintenance operation operation command S2, UP, DO
It is determined whether to execute step M107 for performing door closing control in response to a departure instruction from the WN button, or to execute step M108 for performing door opening/closing control during normal service including automatic door closing.

In this way, not only the circuit becomes independent and has a single function, but also steps M102 and M103 and step M1
05, M107, and M108, it can be easily configured so that only one of the control circuits executes the program, and the processing speed can be increased accordingly. Since this uses a general-purpose microcomputer, K is important.

FIG. 12 is a software sequence circuit diagram showing a specific example of the crowded control program M600.

The signal 822 that makes the 80% full signal valid is K as shown in FIG.
This is a signal that becomes @l" when the venue is % full.

Therefore, in manual operation etc., soft relay WD80A
Elevator - Car heavy electric detection signal WD80 is 'l' when stopped.
11'''.

)'LJLL is a full-occupancy control soft relay, and other circuits are configured to operate so as not to service hall calls while this soft relay is ``1''. As shown in Fig. 4, the soft contact S4 has the role of becoming @1" in the operating mode in which the hall call service is enabled, and forcing the soft relay to be FULL '0" in other operating modes. .

The soft contact 842 is a manual operation command, which is the only operation method to enable the pass button (soft contact PASS), and the pass button causes the soft relay to be FULL @11
II. In addition, when the door is open and the soft contact DS is 10", the fullness detection soft relay described above becomes 1111", the soft relay FULL becomes 1" by the soft contact Wl) 80A. Soft relay F
Once ULL reaches 11'', it self-holds until the door opening operation (soft contact 1 UP, push 1'') is performed by the soft contact FULL.

In this way, the operation method that performs 80% fullness control based on car weight can be changed by correcting or adding the operation command 0PSPC in FIG. 4 without making any corrections to the fullness control circuit shown in FIG. 12. This makes it easier to respond to requests for special operations specific to the delivery destination.

For example, when a customer specifically requests a driving condition in which 80% fullness based on heel weight is valid during automatic operation, but invalid during manual operation, and the driver is solely responsible for determining whether the vehicle is fully occupied, the driving method shown in Figure 4 can be used. It is only necessary to correct the '1'' at the intersection of the code 0PCD=41 and the operation command signal 522A to @0'', which is especially the best means for modifying the software after delivery.

Furthermore, as another example, there may be an elevator that is not provided with a means for detecting 80% of the weight. At this time, the sequence of operation command signals 522A in Fig. 4 may be corrected to all "'C"'θ'', but since the work efficiency is poor, leave it as it is and use it in the operation command output circuit 3a shown in Fig. 3. One location corresponding to the operation command permission specification 0PSPCE will be corrected to disallow it.

This allows efficient response to the presence or absence of signal input from the operating panel or monitoring panel, improving productivity.

As explained above, according to the present invention, the control sequence of the elevator is arranged in a so-called hierarchical structure, that is, by burying it vertically in a top-down manner according to each operation method, the control sequences are interconnected between each continuous operation control device. Since the relationship is loosely coupled, it becomes easy to add a new operation method or change the conditions of the operation method. In addition, the hierarchical structure makes it easier to read the sequence, so it is possible to improve work efficiency during inspections, maintenance, failures, etc., and to reduce the incidence of sequence failures.
