Description

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

Conventionally, in general sequence control, since the sequence is composed of wire logic, the sequence itself is hardware, which directly affects cost and reliability. Therefore, the most important consideration when creating this sequence was to minimize the number of relays and further minimize the 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 of not being able to understand the sequence control functions without an operating manual. This had the disadvantage that sequence failures were discovered after operation.

On the other hand, a similar problem exists in elevator control, but in this case, the operating method and operation of the elevator do not change significantly depending on the delivery destination, so the above method can be applied using the technical know-how accumulated over many years. It was possible to create a sequence using However, it has the disadvantage that it takes a lot of time to confirm when incorporating new functions, and it takes a lot of time to train new designers and inspectors. This will be explained using the conventional automatic door closing control circuit shown in FIG. 13 as an example.

When it is confirmed that all the power supplies are reliable, it becomes "1" and closes. When either the soft contact Z97A or the safety detection external signal SAFTY turns OFF, the soft timer Z49T that constitutes the automatic door closing control circuit
(time limit is 15 seconds), Z48T (timer for independent automatic operation and group management operation, time limit is 5 seconds), and soft relays Z100A and Z100 are all turned OFF. Many other soft contacts are used, and their functions cannot be determined at first glance. This circuit includes a switch input signal HIGH for switching between high-speed running and maintenance operation, a switch input signal X66 for switching to in-car operation, a switch cut signal ATT for switching between manual operation and automatic operation, and a fire control operation command switch input signal FISW. A soft contact is used to request a change in operating mode.

In addition, contact Z49A of the safety drive operation detection software relay that becomes "1" when the elevator stops outside the regular door opening zone under some conditions and the elevator goes to a specific floor determined for each operation such as fire control operation. Contacts related to the state transition of the sequence are used, such as soft relay contacts RT ₁ and RT ₂ , which become "1" when the state returns.

The remaining contacts are control soft contacts directly related to door opening/closing control. The remaining signals are also broadly classified into three types. Operation input signals such as the close button and open button input signals XCL and XOP installed on the car operation panel, and the door close button input signal XCLOSE used to adjust and check the door opening/closing control on the car are This is one of them. Contacts DOP ₁ and DOP ₂ of the door opening operation soft relay become “1” when commanding door opening, running soft relay contact Z10 becomes “1” while the door is running, and “1” when registering a hall call for the middle floor of the elevator service.
Hall call confirmation soft relay contact HCALL
The second type is the signal of other operating circuits such as . Soft timer delay action contacts Z48T ₁ , Z49T ₁ and door close holding soft relay Z100A contacts Z100A ₁ to Z100A ₃
and door opening/closing control soft relay Z100 contacts
The third type is the door opening/closing operation status signal such as Z100 ₁ .

Now let's check how the door opening/closing function works as shown in Figure 13.

Z97A, SAFTY and HTGH are “1”, and X66 and
Let's consider what types of driving methods are possible in which ATT is in the "0" state.

Applicable operation methods include normal automatic operation (which can be divided into group management operation and independent automatic operation), private automatic continuous operation, parking operation, executive-only operation, drain operation of elevators with coolers, and the above-mentioned safety drive operation, and each floor. It includes a number of operating methods, such as a floor height measurement operation for measuring floor pitch.

Then the elevator completes its run (Z10=
Let's consider how many seconds it takes for the door to close automatically after the door is opened (DOP ₂ = "0").

The fastest is when FISW = "1", RT ₂ and XOP are "0", and it is immediate. What kind of operation method is this? It is the time of fire control operation method. Furthermore, there are conditions for automatic door closing in 5 seconds and automatic door closing in 15 seconds, but it is extremely difficult to read these conditions from a circuit diagram, and the conventional circuit shown in Figure 13 is easy to understand. It was not possible to change the function.

Further, the full occupancy detection operation circuit shown in FIGS. 14a and 14b will be explained as an example.

In the past, it was generally customary to configure a circuit with the minimum necessary number of contacts, as shown in FIG. 14a. This is not just a matter of replacing the hardware relay circuit with software. Normally, conditions related to the operating method should be included, as shown in Figure 14b, but adding this has the disadvantage of increasing the program capacity, but the biggest problem is the lack of processing time. be. For this reason, conventionally the 14th
As shown in Figure a, all unnecessary contacts were omitted. For this reason, the automatic full detection relay WD80A,
It became unclear under what conditions the full-crowd passage command relay FULL was originally designed to be used, and
For example, the microcomputer itself did not stop due to a momentary power outage, but the load detection circuit malfunctioned and the full occupancy detection capture signal WD80 turned ON momentarily.
When changed to , WD80A turns ON and contact WD80A ₁
The full pass command relay FULL turns ON, and the contact
A defect held by FULL ₁ occurs.

On the other hand, if the configuration is as shown in FIG. 14b, the soft contact Z97A turns OFF upon detection of an instantaneous power failure, thereby making it possible to prevent the above-described potential failure from occurring.

In addition, IPASS can be used not only during manual operation in hospitals, etc. This is a specification for switching operating conditions for each delivery destination, which is set to "1" when the pass button is enabled even during automatic operation. IWD80Q is a spec that disables the 80% or more fullness detection relay contact WD80A ₁ during manual operation, and switches the operating conditions so that the hall call passing operation is performed depending on the driver's judgment.

By preparing such flag-like specifications, it may be possible to avoid modifying the program, but the number of these specifications increases abnormally, and it becomes difficult to know which specs should be modified and what will happen when designing or changing specifications (modifications). Reconfirmation could only be carried out by highly skilled engineers who were able to read each individual control circuit, and for this reason, maintenance personnel at the end of the line were unable to use specs to switch specifications.

An object of the present invention is to provide an elevator control device whose sequence is easy to read and whose functions can be easily changed or added.

In order to achieve this object, the present invention provides an elevator control device that inputs an operation method instruction input signal and an elevator control state signal, and selects the operation method instruction input signal and elevator control state signal from among a plurality of set operation methods. Depending on the elevator, at least door opening/closing control, car call control,
An operation mode selection circuit that selects an operation mode that collectively determines a plurality of operation modes including operation modes of control completion control and speed abnormality control and outputs an operation mode signal, and an operation mode selection circuit that outputs an operation mode signal by inputting the above operation mode signal. an operation command circuit that outputs an operation command that instructs the operation conditions of the elevator according to the method; and at least a door opening/closing control circuit that inputs the operation command and performs operation control under the instructed operation conditions;
It is characterized by being constructed from a plurality of basic operation circuits including a car call control circuit, a control completion control circuit, and a speed abnormality detection control circuit.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments.

FIG. 1 is a block diagram showing a schematic configuration of an elevator control device according to the present invention.

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

Of the hundreds of elevator input/output signals, several dozen operation method instruction input signals from the operation panel and monitoring panel 1a, etc., related to the basic functions of elevator operating conditions (the functions of the basic operation circuit described above).
OPINP is input to the operation mode selection circuit 2, and most of the other input/output signals are directly connected to each of the basic operation circuits 4a to 4n, although not particularly shown. In addition, the elevator control status signal ST is
These are a failure detection signal of the elevator control system outputted from the elevator operation control circuit 4, a signal indicating the elevator is stopped, a return to a specific floor level is completed, etc., and these are also input to the operation method selection circuit 2.

Therefore, the operation command signals S1 to S64 instructing the operation conditions corresponding to the operation method code OPCD selected by the operation method selection circuit 2 are sent to the operation command circuit 3.
A plurality of basic operating circuits 4 are outputted from a plurality of basic operating circuits 4 under operating conditions instructed by these operating command signals S1 to S64.
The elevator operation control circuit 4 consisting of a to 4n controls the operation of the elevator.

In this way, by arranging the control sequences vertically in a so-called hierarchical structure, that is, in a top-down manner according to the operation method, the relationships among the basic operation circuits 4a to 4n in the horizontal direction at the same level are reduced. Coupling can be made more loosely than before. In particular, the operating method instruction signal OPINP and the control status signal ST
By completely eliminating the signals related to the complicated contact combinations scattered in the middle of the basic operating circuits 4a to 4n, an operation instruction signal S with clear operating conditions is created.
1 to S64 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 4n already have as standard, or the functions that can be realized by a combination of them. For example, 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.

In addition, when adjusting, inspecting, maintaining, or malfunctioning the elevator, the operating method code OPCD can be sent, for example, to
By checking the display on the elevator control panel or elevator monitoring panel, you can immediately grasp the current status of the sequence, and you can also check the sequence operation for each operation method by simply looking at the operation instruction spec table of the operation command circuit 3 and the operation method code OPCD. Since the operating conditions of the system can be grasped, the sequence becomes much easier to read than before, which improves work efficiency in inspections, maintenance, etc., reduces the incidence of sequence failures, and shortens recovery time in the event of a failure. can do. This effect is important when a sequence is constructed from a semiconductor circuit such as a microcomputer. That is, in the past, the current state of the sequence could be grasped by relay operation, but when semiconductors are used, the sequence cannot be known 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 due to the large number of signals. This effect is important because it is necessary to input the address of the sequence signal using a key and confirm the contents.

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

The driving method selection circuit 2 is the driving information control circuit 2.
a, a priority relationship determination circuit 2b, and an operation method output circuit 2c.

Signals that require special processing among the operation method instruction signal OPINP and the control status signal ST are input to the operation information control circuit 2a, where the information is aggregated, restricted, temporarily held, etc., and designated information that specifies the operation method is generated. Output signal OPST.

In the priority relation determination circuit 2b, the designation information signal OPST specifying these driving methods, the driving method instruction signal OPINP and the control state signal ST that are directly input are used.
Among them, the designated information signal with the highest priority is selected and output as the driving method selection signal OPCD1.
Generally, an operation method with a high degree of operational restriction is selected preferentially, and control is performed to maintain the safety of the elevator.

In the driving method output circuit 2c, the driving method selection signal
It is determined whether or not OPCD1 is the operating method defined for the actually delivered elevator based on the operating method output permission spec OPCDE, and if it is permitted, this is output as the operating method signal OPCD. In addition, in the case of a driving method that is not permitted, the driving method signal 00 (see Figure 4), which represents the driving method of pause 1 due to the selection of an undefined driving method, is sent to the driving method signal.
Output as OPCD.

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 a plurality of operation command output circuits 3a to 3f.

The operation command selection circuit 3x selects the operation command S1A, etc. corresponding to the operation method signal OPCD as an operation command specification.
Select from OPSPC and output.

Here, the relationship between the operation method and the operation command signal is explained in the fourth section.
As shown in the figure.

The operation command signals S1A to S40A are logical signals of "1" and "0", and can be used as they are in the elevator operation control circuit 4. Therefore, the operation command output circuit 3a simply outputs the operation command permission specs necessary for elevator control at this delivery destination.
It simply performs the AND with OPSPCE and outputs it.

On the other hand, the operation method classification signal command SICD, the automatic door closing time conditions for elevator doors (conditions for the door to start closing when the idle time is 0 seconds, 2 seconds for car call service, 3.5 seconds for hall call service, and on the standard floor) Automatic door closing command DRTCD, which commands the conditions for the door to start closing in 5 seconds, etc., speed command VCD, which commands the maximum operating speed, and specific floor command, which commands waiting or calling to a specific floor.
The FLRCD, fault detection command TCD that instructs the range of fault detection, etc. are encoded into pure binary numbers and output. Therefore, the operation command output circuits 3b to 3f convert these encoded command signals into signals that are easy to use in the elevator operation control circuit 4.

FIG. 5 is a truth value explanatory diagram showing the function of the operation command output circuit 3b, and shows the operation method classification signal command SICD.
When is 00, no operation command is output.

Moreover, FIG. 6 is an explanatory diagram showing an example of the function of the operation command output circuit 3e, and is an explanatory diagram showing an example of the function of the operation command output circuit 3e.
Actual floor name and specific floor signal depending on the conditions and specifications of the building where the elevator is installed.
Establishes SFLNO.

Although the embodiments of the present invention have been explained above, in order to make the present invention more specific,
An example in which a microcomputer (hereinafter abbreviated as microcomputer) is used as the sequence control circuit will be described below.

FIG. 7 is a flowchart of program PGM1, which starts processing as soon as the power is turned on.

Initialization program M100 is used to set the initial values of the programmable LSI that makes up the microcontroller.
Initialize RAM (generally clear all areas to “0”). The stack pointer is also set at the same time. The next step M110 is to determine whether communication with the group management microcomputer is normal.
If YES, data transmission/reception control processing with the group management microcomputer is performed in step M120, and step M120 is performed.
Set the communication link signal MLNK to "1" using M130. If the determination at step M110 is NO, the communication link signal MLNK is reset to "0" at step M140. Next, in step M150, monitor control is performed to display and transmit the sequence status on a display such as an LED or CRT.

Figure 8 shows a machine control program that is started in priority over the program in Figure 7 by an interrupt that occurs periodically after the execution of step M100 in Figure 7 is completed.
Shows the general flowchart of PGM21.

In FIG. 8, the timer control program in step M400 is first executed, and the sequence program PGM21 manages and controls the expiration of the timer for which a count is requested. Next, in step M440, input signals from outside the microcomputer are collectively input into the microcomputer as information.

Although the present invention relates to the machine control program PGM21 shown in FIG. 8, the explanation will be omitted here, and only the programs directly related to the present invention will be explained in FIGS. 9 to 12, which will be described later.

The processing results of these sequence programs PGM21, that is, the control output data, are
By outputting them all at once using M690, it is possible to, for example, turn on a car response light or issue door opening/closing control commands.

When the above processing is completed, all the processing of the interrupt program is completed, and the process returns to the repeating process shown in FIG. 7 again.

Next, a detailed explanation of the control processing of the driving method control circuit 1 will be given with reference to FIGS. 9 and 10.

FIG. 9 shows a part of the driving information control circuit 2a. Power supply establishment soft relay Z97A is a voltage confirmation input signal soft contact of hard relay circuit for safety control
PWON ₁ and ON that turns on for a certain period of time after microcontroller startup
It is determined whether the basic conditions for starting sequence control of the soft contacts ONT ₁ of the timer are satisfied. Also, there is a power outage in the normal power supply (NPW ₁ is “0”)
At this time, the emergency power supply (MPW ₁ is "1") controls multiple elevators to return one by one to the first floor of the standard floor. This sequential return control is 1
A return command is input to the elevator, and the soft relay contact SSW ₁ becomes “1” and the soft relay
This is done by turning on Z97A.

In addition, after all the elevators had completed their return one by one, only the soft relay Z97A of the elevator in which one elevator was commanded to continue (soft contact TSW ₁ was set to "1") turned ON, and only that elevator Service operation is now possible, and the other elevators are
As shown in FIG. 4, the operation mode is set to power standby (OPCD) by the priority relation determination circuit 2b of the operation mode shown in FIG.
=01), resulting in a complete stop.

Soft relay SLA is used to control when the elevator is running at high speed and the maintenance operation switch on the operation panel is turned ON (soft contact SLOW ₁ and SLOW ₂ in Fig.
It does not turn ON until SPCH ₁ becomes “0”). The soft contacts SLOW ₂ and SLA ₂ in Fig. 10 cause the operation mode signal to be sent in step M489 until the machine stops once.
Set OPCD1 to 00, select the operation mode of pause 1 as shown in Figure 4, set the failure detection command TCD shown in Figure 3 to 00, at least prevent low speed overspeed detection, and prevent malfunction of failure detection. prevent.

The soft relay RT is a return detection soft relay that detects when the car has returned to a specific floor due to traffic control or parking orders.
Judge with M471, and when it matches, soft relay RT is activated.
Turns ON, and turns OFF when there is a mismatch.

The soft relay FIRT has detected the complete completion of the fire, and the soft contact S55 ₁ of the fire control operation command outputted from the operation command output circuit 3b in Figure 3 under the conditions shown in Figure 5 is "1", and the above When the soft contact RT ₁ of the return detection soft relay RT is “1”,
In other words, it becomes "1" when fire control is completed.

Figure 10 shows, in addition to the above-mentioned consolidated operation commands, a safety detection external signal (soft contact SAFTY ₁ ), an internal signal consolidating serious failure detection (TBB ₁ ), and the purpose of can rescue and construction operation without using a microcomputer. an external signal that commands low-speed operation (MSLOW ₁ ), an external signal that commands fire control (FISW ₁ ), an internal signal that consolidates intermediate failure detection (TBD ₁ ), and manual operation using the manual operation switch on the operation panel The operation method is selected in the priority order shown in the circuit using soft relay contact signals such as a command signal (ATT ₁ ) and an internal signal (MLNK ₁ ) that detects that communication with the group control microcontroller is normal, and steps are performed. Create operation mode selection signal OPCD1 using M482 to M499. This signal then passes through the operation mode output circuit 2c of FIG. 2 and becomes the operation mode signal OPCD, which outputs the operation command as shown in FIG. 5 to control the operation of the elevator.

Here, in the case of microcomputer control, the operation command specifications shown in Figs. 4 to 6, the operation command permission specifications OPSPCE used by the operation command output circuit 3a, the operation method output permission specifications OPCDE used in the operation method output circuit 2c, etc. can be a group of codes arranged and arranged in a certain order, and the majority of sequence conditions can be corrected just by modifying this, so not only is modification and new design easy, but also
The sequence becomes much easier to read because the diagram allows you to understand the outline of the sequence.

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 103 is executed. step
As can be seen from Fig. 4, M104 detects that both operation commands S1 and S2 are "0" in an operation method that stops or pauses the elevator, executes step M105, and also stops opening/closing the door. to control. Step M106 determines the maintenance operation command S2, and executes step M107, which controls door closing in response to a departure instruction using the UP and DOWN buttons, or executes step M108, which controls door opening and closing during normal service, including automatic door closing. Decide what to do.

In this way, the circuit becomes independent and has a single function, as well as steps M102 and M103, and steps M102 and M103.
Operation control that can be easily configured so that only one control circuit executes the program, such as M105, M107, and M108, and has the functions that that part should have independently of other circuits. Since the circuit can be designed, the circuit design becomes easier.

Further, troubles caused by mutual interference that occur after the operational control circuits that implement each function are completed are greatly reduced. This type of defect is difficult to detect and is often discovered after the product is handed over to the customer. This is a particularly important point for an elevator control system that prioritizes safety and reliability.

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

As shown in FIG. 4, the signal S22 that makes the 80% full signal valid becomes "1" during manual operation, etc.
Soft contact RUN ₁ is a running signal, soft contact
WD80 is a signal that becomes "1" when the venue is 80% full.

Therefore, the soft relay WD80A outputs the car weight detection signal when the elevator is stopped during manual operation, etc.
Becomes “1” when WD80 is “1”.

FULL is a fullness 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 becomes "1" in the operating mode in which hall call service is permitted, and has the role of forcing the soft relay FULL to "0" in other operating modes. Soft contact S42 is a pass button (soft contact
This is a manual operation command, which is the only operation method to enable PASS), and the soft relay FULL can be set to "1" by pressing the pass button. In addition, when the door is open and the soft contact DS is "0", if the full occupancy detection soft relay described above becomes "1", the soft relay FULL is activated by the soft contact WD80A ₁ .
becomes “1”. Once the soft relay FULL becomes "1", it self-holds until the door opens by the soft contact FULL ₁ (soft contact DOP ₁ is "1").

In this way, the operation method that performs 80% fullness control based on car weight does not require any correction to the fullness control circuit shown in FIG. 12, and the operating command specs shown in FIG.
Changes can be made by correcting or adding to the OPSPC, making it easier to respond to requests for special operations specific to the delivery destination.

For example, during automatic operation, 80% fullness based on car weight is valid, but during manual operation it is invalid, and when a customer specifically requests driving conditions that allow the driver to make the full judgment, the driving method shown in Figure 4 can be used. code
All you need to do is correct the "1" at the intersection of OPCD=41 and the operation command signal S22A to "0". In particular, it can be said to be the best method for modifying software after delivery.

Another example is an elevator that does not have a means for detecting 80% of the car weight. At this time, the operation command signal S22A column in Fig. 4 is all set to “0”.
It may be corrected to , but since the work efficiency is poor, we will leave it as is and correct one location corresponding to the operation command permission spec OPSPCE used in the operation command output circuit 3a shown in FIG. 3 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 elevator control device selects the operation method instruction input signal and the elevator control state from among a plurality of operation modes set by inputting the operation method instruction input signal and the elevator control state signal. At least opening/closing control of elevators, car call control,
An operation mode selection circuit that selects an operation mode that collectively determines a plurality of operation modes including operation modes of control completion control and speed abnormality control and outputs an operation mode signal, and an operation mode selection circuit that outputs an operation mode signal by inputting the above operation mode signal. an operation command circuit that outputs an operation command that instructs the operation conditions of the elevator according to the method; and at least a door opening/closing control circuit that inputs the operation command and performs operation control under the instructed operation conditions;
It consists of multiple basic operation circuits, including a car call control circuit, a control completion control circuit, and a speed abnormality detection control circuit, and the elevator control sequences are arranged vertically in a top-down manner according to each operation method. The relationship between the operating circuits is loosely coupled, and as a result, it becomes easy to add a new operation method or change the conditions of the operation method. In addition, by organizing vertically in a top-down manner as shown above,
Since the sequence becomes easier to read, it is possible to improve work efficiency during inspections, maintenance, failures, etc., and also to reduce the incidence of sequence failures.
