Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a computer-controlled elevator control system, and more particularly to a control system suitable for elevators that is controlled using multiple data transmission lines.

[Conventional technology]

With the enrichment of elevator services, the communication between the elevator control device and the car position display, hall call device installed at each landing, destination floor call registration device installed inside the car or at the landing, etc. The number of wiring lines continues to increase.

Therefore, various proposals have been made to reduce the number of wires, examples of which are JP-A-47-41499, JP-A-52-152050, and JP-A-52-5335.
It can be seen in each publication of No. 4.

Apart from this, a proposal was also made in JP-A-61-696 to reduce the number of wires by installing a microcomputer on each floor and transmitting data serially.
This can be seen in publications such as No. 77 and Japanese Patent Application Laid-open No. 194943/1983.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not give consideration to the versatility of the control device, and has the following problems.

■ The number of input/output signals increases in proportion to the increase in the number of floors, and the installation of panel displays and destination call registration devices to display service floors and waiting times at landings (port type electronics). It is necessary to either increase the transmission speed (coaxial cables or twisted pair wires need to be used, which increases costs), or to lengthen the I10 processing cycle.

■ As mentioned above, the number of floors and guide indicators for elevators differ depending on the destination.

For example, even if it is a platform call registration device,
Use of a wheelchair (ascending/descending).

There are a wide variety of models, including those that use elevators going to the basement floor and elevators that go to the rooftop floor, and some have eight sets of phase inputs and response lights.Therefore, each case requires a different series transmission procedure depending on the specifications. I guess they were designing and manufacturing input/output terminal devices with different input/output circuits.
In addition to being difficult to mass-produce, one-chip microcomputers and mask ROMs, which have been significantly reduced in cost in recent years, cannot be used, making it extremely difficult to reduce costs.

An object of the present invention is to provide an elevator control system that has sufficient versatility, can be easily applied to elevators of any specification, and can easily achieve significant cost reductions.

Furthermore, according to the present invention, even if the number of elevator service floors, various guide devices, or operation buttons increases or decreases, the hardware of the elevator control device remains the same, and each floor or floor or car Sufficiently minimize the types of input/output terminal devices that are installed in locations such as inside or above the elevator, in the elevator machine room, in the pit (lowest part) in the elevator hoistway, and in remote control stations (monitoring rooms and reception areas). In addition to being able to reduce and standardize easily,
Wiring between the above-mentioned elevator control devices can be simplified to provide an inexpensive line.

That is, according to the present invention, it is an object to construct an elevator control system that can be flexibly handled both in terms of hardware and software.

Additionally, in recent years, flat displays capable of multi-functional displays are often installed inside cars and at landing areas, and port-type indicators that integrate a destination floor registration device and car position display are often installed at landing areas. According to the present invention, even in this case, diversified and complicated operations and control of guidance equipment can be easily handled using as few types of input/output terminal devices as possible.

[Means for solving problems]

The above purpose is to provide terminal specification data that determines control operations by the input/output terminal control device to the host control device each time in a system in which elevator control is performed separately to the host control device and the input/output terminal control device. This is accomplished by transmitting the information from the input/output terminal controller to the input/output terminal controller, storing it, and having it perform control operations.

[For production]

The input/output terminal device receives terminal specification data that defines the specifications of the input/output terminals of each terminal device, the relationship between input and output, etc. from the host control device, and performs control operations based on the terminal specification data.

Therefore, it is possible to support a wide variety of elevator systems without changing the hardware configuration of the input/output terminal device.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the elevator control system according to the present invention will be explained in detail with reference to illustrated embodiments.

Here, the features of the present invention will be briefly explained based on examples as follows.

First, in the present invention, (1) A one-chip microcomputer with a communication circuit or a gate array LSI is incorporated into the input/output terminal device, and terminal specification data that defines the specifications of the input/output pins of each terminal and the relationship between input and output is electronically controlled. The information is received from the equipment or elevator group management control device (hereinafter abbreviated as host).

■ The cycle for checking all slave stations (abbreviation for the serial transmission circuit that interfaces with the serial transmission line connected to each input/output terminal device) is relatively slow (33.3 m5), and the bus wiring route is inexpensive. .

- Each input/output terminal device controls the lighting of the hall call response light according to the terminal specification data received for the terminal from the host, so as to avoid the delay in response light due to the above-mentioned transmission cycle. In addition, the host adapts to the operation mode such as maintenance, non-stop command, express operation, etc. 2. It creates terminal specification data corresponding to each input and output signal of each terminal, and sends it to each terminal in a timely manner. - By configuring as above, a. When the power is turned on, terminal specification data from the host has not yet been transmitted, so a false hall call signal may be input due to a transient phenomenon, etc. However, it does not work, and the response light turns on by mistake.
There is no risk that the call will be registered.

b. When the elevator is in service, terminal specification data necessary to perform appropriate control in response to input signals from the host is transmitted to the terminal in advance, and this causes the elevator to press the call button. immediately (e.g. 5
It is possible to perform reaction control such as response light lighting control and touch sound generation control within 0.1 seconds).
cause a complaint).

C1 On the other hand, input signals from various operation buttons and detectors are transmitted to the host, and the host performs necessary processing such as call registration processing control.As a result, the elevator operation is controlled and the registered call signals etc. The operation control data of the terminal is sequentially transmitted to each slave station within the terminal, along with guidance signals and the like.

As a result, upon receiving these control data, the terminal side executes a service based on the call registration signal, instead of the temporary answering light lighting control based on the above-mentioned call input signal and terminal specification data, for example. The response light can be kept on until the call registration is cancelled.

Now, Fig. 1 shows the overall configuration of one embodiment of the present invention, and the present invention is applied to an elevator system having service floors from BIF to 3rd floor (however, 3rd floor is omitted). The elevator control device (host) is connected to the I10 transmission control device 2, and is connected to the input/output terminal devices (hereinafter referred to as terminals and Abbreviations) 4a to 4c, 6.13 and bus (serial data transmission line)
3a and 3b.

■/○ The transmission control device 2 polls each of the terminals 4a to 4c and 6° 13 one after another, and sends and receives information unique to each floor, such as call buttons and their response lights.

Terminals 4a to 4c serving as floor stations are connected to hall operation panels 5a to 5c.

Then, each terminal 4a to 4c detects whether or not the call button has been pressed, and when polled for the result,
The data is serially transmitted to the transmission control device 2 through ) to transmit information.

Next, the host 1 performs a registration process for car calls and hall calls, transmits information to each terminal 43-4c through the reverse route to that described above, and controls the lighting of the response lights of the hall operation panels 53-5C.

However, the above response light lighting control method alone is not enough.
As described later using Figure 5, the response light lighting delay is 0.1
In this embodiment, as described above, terminal specification data is provided for each input/output terminal device in response to a call button that provides service in the manner described above. is transmitted from the host, and each terminal performs local control to drive a response light lighting output corresponding to the call button human power for a predetermined period, thereby solving the problem of the lighting delay described above.

As mentioned above, the embodiment shown in FIG. 1 shows the case of an elevator that serves a total of four floors, from the first underground floor (BIF) to the third floor above ground (3F).

In addition, in this embodiment, on the 81st floor there is a parking switch (PAK) 16 and an information display DT that can indicate full occupancy, etc.
An indicator 73 whose light source is an LED with a is installed at the top of the elevator hall, and these devices are connected to a BIF input/output terminal device ff 4 a for input/output control.

By the way, the first floor is a lobby with many users. Therefore, we have installed an operation panel (hereinafter referred to as a boat-type indicator) 5b that registers the destination floor directly at the platform and also indicates the position of the leading car of the elevator, and a slightly larger lamp-type indicator 7.
Note that the audio reproduction circuit 14 can be omitted if it is incorporated into the small terminal device 4 whose details are shown in FIG. 3.

On the other hand, since the second and third floors are general floors, the information display 8a
Normally, only the cart position and service direction are displayed using the BIF, as shown in Figure 5 (a).
In the IF, one set of human output terminals is used for each floor, as shown in FIG. 5(b), but it is also possible to use one set for each second floor. In particular, in general hall call registers connected to elevator group management control equipment,
Since there are fewer signal lines, one set per six floors can be standard.

The transmission path from the master station 2 to the terminals 6 and 13 in the car is connected by a bus 3b including a tail cord. The reason why it is separated from the bus 3a to the boarding point is to prevent malfunctions due to reflections or the like.

As shown in Fig. 4, the terminal 6 in the car uses a medium-sized terminal device 6 with many input/output points, and is used for car calls and closing buttons (CL).
In addition to OS E), automatic (AOUT).

It takes in manual and normal (NOMAL) signals as well as signals such as car weight detection and landing level, and drives an in-car indicator 10 installed in the car upper part including an information indicator DIO which can also display the time. It has become.

On the other hand, the terminal 13 on the car does not have as many ink faces with the outside as the medium-sized terminal 6, but it is used to issue opening/closing control commands to the door drive device=12-11 and output the brake signal L2. It is necessary to be able to receive a large number of control parameters etc. from the host 1.

This terminal 13 receives the opening command on line L1, the signal from the passenger detection device 12 using a photoelectric device or an ultrasonic sensor on line L5, and the door opening/closing speed and position on line L3. It has become a multi-functional terminal by not only controlling input/output circuits but also controlling door opening/closing.

As a result, data transmission can be performed at low cost, and compared to when the door opening/closing control device is independent, there is no need to separately adjust the specifications that determine the speed and current using Dip-sws, trimmers, etc., and the terminal specifications ■ On-site adjustment data can be centrally managed on host 1 (no readjustment required even if terminals are replaced).

(2) A door opening/closing control command can be given to the door driving device 12 according to the situation through sophisticated judgment by the host.

Benefits such as:

A host (elevator control device) 1 connects a group management control device, a maintenance device, a monitoring panel, a terminal device for a remote monitoring system, a receiving terminal for an information input/registration control system, etc., and transmits data via a network transmission control device 17. A bus connection is provided by line 18. This makes it easy to set up a group management system.

According to the above explanation, the input/output terminal device with bus type transmission line 4,
By using 6.13, even if the configuration of the elevator control system changes, especially the operation equipment and guidance equipment at the landing, or even if the number of floors increases or decreases, it can be standardized without developing new hardware. The person concerned will understand that it is possible to create a system by combining highly reliable and inexpensive hardware.

FIG. 2 is a hardware configuration diagram of the microcomputer 100 that determines the control logic of the elevator control device N (host) 1 and the I10 transmission control device 2.

In this embodiment, a dual port RAM (hereinafter referred to as DPRAM) is used.
) 301, the CP UIOI and CPU U2O5 in the two devices described above are connected to the Has 107, respectively.
and 210 maintain a relatively tight coupling.

CPUl0I in the elevator control device 1 is DP R
A M2O3 stores the following two types of data as shown in FIG. 14 in the DPRAM according to the operation flowcharts of FIGS. 6 and 7.

■ CPU in I/D transmission control device 2 Stores basic transmission control specifications and management specifications used by U2O5.

As a result, various execution programs, which are standardized by modularization in the ROM 207 and made into a mask ROM, create various transmission control forms based on this specification data. For example, as outlined above, by installing two units in parallel, it is possible to make the network transmission control unit 17 for connecting with other machine control units completely identical in both hardware and software (programs and data in ROM). Become. That is, the type Ki

Depending on the value of the master station specification data DATA, which determines the handling when an error occurs, etc., various types of transmission can be commanded from the host. Also, depending on the judgment of the elevator control device Wl, such as whether or not it is maintenance time, the elevator may lengthen the transmission cycle TM, or issue commands for permission to sequentially move the bus control right to the information control station or maintenance station for a predetermined period. New commands can be issued at any time even during service.

■ Terminal specification data 5 that is sent from the master station to each slave station and determines how to use the hardware and control specifications of the input/output terminal of the slave station.
Create CTXS to 518TXS and control data 5CTXD to 318TXD required for each slave station.

Here, 5CTXS is terminal specification data common to all slave stations, and S I TX S-318TXS is terminal specification data for the 18th slave station from the 1st slave station (in-car input/output terminal device 6 here). be. The CPU 205 on the master station side is a DPRAM
The data of 301 is transmitted from the serial interface (hereinafter abbreviated as SI) to the transmitting circuit 202 in various amounts in the order shown in FIG. 12(a). The signal is transmitted by the pulse transformer 201 to all the slave stations via the transmission line 3 according to the operation flow detailed in section 9.

Here, 5CTXD is control data common to all slave stations,
As shown in FIG. 13(b), all basic data is transmitted to accommodate various specifications.

In addition, the S ITXD-318TXD is capable of transmitting signals from the first slave station to the first
This is control data for eight slave stations, and is transmitted sequentially as shown in FIG. 13(a).

In either case, the first slave station of the in-car input/output terminal bag W6 and the fourth slave station for the terminal device 4b of the IF equipped with a port type indicator transmit data (MS ITX, !j, MS
The amount of both TTXD) and received data (MS4RX) is larger than other stations. Therefore, as shown in FIG. 14(b), the role of the transmission management specification table is to manage these transmission and reception data tables.

Although various improvements have been made to Fig. 2, only some of them will be supplementary explained.

First, the write range from CPU2O5 is shown in Figure 14 (
Write address restriction circuit 30 that restricts as shown in a)
2, in order to investigate the cause and improve the probability of natural recovery in the unlikely event that an abnormality occurs.

Next, connecter CN2 is installed on the host microcomputer 100, and an analyzer or maintenance
It can be used to connect debug tools and to connect the 2nd I10 transmission control device when going beyond the 16th floor.

Therefore, if you change the type of display on a particular floor,
EEP that contains the host side specification data or program to create terminal specification data when the first floor is added.
The ROM 103 can be easily modified using a maintenance/debugging tool.

However, in the conventional example, it was necessary to add a program to the ROM 207 and the ROM 2O3 for the slave station on the specific floor shown in FIG. 3, and to remanufacture it. This can be said to be an extremely important improvement, since it would take about one month and a considerable amount of money to create a mask ROM.

Furthermore, the effect of unifying the hall slave stations into the circuit shown in FIG. 3 or FIG. 4, which will be described later, is great, especially when the serial transmission method is 21! This is an important point in order to widely put into practical use the W floor to the 60th floor.

Further, in this embodiment, the elevator control microcomputer 10
0 and transmission control devices 2 and 17 are integrally mounted on a single printed board PB to improve noise resistance.

FIG. 3 is a diagram showing the hardware configuration of a small input/output terminal, and FIG. 5(a) shows an example of the connection at the BIF, and FIG. 5(b) shows an example of the connection at the IF. As shown in Figures 10 and 11, the CPU 4O5 included in this creates a parallel interface (hereinafter referred to as P

(approximately 10ms), and data transmission/reception control is performed by the SI (serial interface) 606.
This is executed by an interrupt process activated by an interrupt signal generated upon completion of data reception after a wake-up pulse.

In the embodiment shown in FIG. 3, the following measures have been taken to improve versatility and reliability.

■ Input-only terminal T using PI413 and input circuit 418
PI412.
40B, and input/output switching terminals T409 to T416 controlled by an input circuit 417 and an output circuit 416, making effective use of the number of input/output points.

This is because the power transistor Tr of the terminal device 4 generates heat.
Most of the general IC circuits including 400 are custom LSi
When converting into a hybrid IC or a hybrid IC, the number of terminals becomes an absolute condition, rather than the size of the internal logic, and determines the size and cost, so this is an important idea.

According to the terminal specification data transmission method according to the present invention, as shown in FIG.
0'' is output, and all 8 points of input circuit 417 are prohibited.
Alternatively, the output circuit 416 can drive a load as shown in FIG. 5 using signals from the PI 412 at all eight points.

FIG. 5(b) shows an example of the connection of the port type indicator 7 up to the 8th floor with dotted lines. For example, in the case of the 12th floor, input/output terminals T409 to T412 have terminal specifications on the input side. switching (Q4 of P-408 is "1"), output terminals T417-420. Input/output terminals T413 to T416
may be used as it is on the output side, and an LED indicator that also serves as a destination call response light (continuous light) and a car position indicator light (blinking light) may be controlled.

Therefore, according to this embodiment, changes in these terminal specifications are performed not in the ROM2O3 but in the host's EEPROM103.
As a result, excellent effects can be obtained in terms of design, manufacturing, and maintenance.

Other ideas include: ■ In order to check the movement of the CPU 4 O 5, the power supply circuit 415 is equipped with a function to detect that the pulses output every period TS are no longer output due to an abnormality in step 600 of FIG. 10; and when it operates - CPU U2O
5 and stores it in the memory circuit 414, suppresses the output circuit and the transmitter circuit 402, and prevents careless operations, thereby executing operations that may raise doubts about safety or suspicious guidance. This is useful for preventing unexpected misunderstandings from occurring to users, and for allowing normal transmission control of terminal devices on other floors to continue as they are.

If there is a momentary power outage or a temporary voltage drop, there is a high possibility that devices near the end of the power supply path of the power supply P22 will temporarily malfunction, but in this embodiment, the boss 1 The abnormality is diagnosed in step C305 shown in FIG. 8, and when the elevator is stopped and the door is open, an INIT header is sent only to the slave station, and step 5 in FIG.
920, S 930. S935. The pulse that resets the memory circuit 414 via S940 is sent to Q6 of the PI.
Since the output is output from the terminal, the above-mentioned suppression is released, and normality is restored, malfunctions can be suppressed.

■ The slave station number is P'! at step 5250 in FIG. 4
13 I. Alternatively, it can be created by inputting the code according to (1) and written to the EEPROM 414 in step 260.

At this time, it is necessary to cut the wiring to the transmission circuit 3 or input the I10 transmission cut mode using the maintenance adjustment function of the host.

FIG. 4 is a hardware configuration diagram of the medium-sized input/output terminal device 6 used in the car. The CPU U2O5 has the same number of ROM2O3, RAM2O3, and EEPROM as shown in Figure 3.
614, P T 608.611.612.613 and 5I606, as a result, the microcomputer section 600
can be made completely the same as the microcomputer section 400, software (ROM2O3 data), and hardware in the terminal shown in FIG. This is a great practical effect of adopting this control method. For example, on the 12th floor, which is equipped with a boat-type indicator as explained earlier as an example, the lamp-type indicator 7b may be installed on the 12th floor, which is equipped with a boat-type indicator, similar to the first floor in FIG.
If the device is equipped with a voice guidance system 14 or 15, the absolute number of input/output points will be insufficient in a small device.

According to this embodiment, a new or remodeled elevator control system can be planned to use a medium-sized elevator control system for such floors. and,
If you use a medium-sized one, you can easily adapt to specification changes by configuring the input/output circuit to be block-selected by PI6L1 and the input/output to be selected by the output Q4 of Pr2O3 (the input circuit lives in "do"). And, according to this medium-sized model, if only boat-type indicators are installed on all floors, it is possible to input destinations for 64 floors and control the lighting of response lights. Even when
For this purpose, rather than going to the trouble of developing large-sized input/output terminals, it is better to install two sets of medium-sized input/output terminals on the same floor and distribute their functions, which is more scalable and helps recover development costs. It is estimated that it is good from the point of view.

However, just in case, there are 25 port-type inns on all 64 floors.
- =24- When there is a specification for the indicator, the I10 transmission control device (abbreviated as the master station) is used to control the I10 transmission bus via connector CN2 so that 16 to 18 slave stations are assigned to every 8th to 9th floor.
It is necessary to add 7 sets of 2.

In consideration of these applications, some examples are shown in FIGS. 12(e) and 12(f). In addition, this Ilo
It is necessary to prepare other terminal specifications in addition to these l101.2, but they are not shown in the figure.

FIG. 5 is a wiring diagram showing an example of how the input/output terminal device 4 is used at a boarding point.
b) shows those at IF.

Here I will only explain the parts that seem particularly difficult to understand.

- The information display D7a is of a type in which characters and figures are displayed for each code. Code 0 is not displayed, Sl is displayed as "Full", S2 is displayed as "Auto", S3 is displayed as "Suspended", S4 is displayed as "Please wait for about 10 minutes during inspection", and S526 is displayed as 1 - Out of order. "Please wait for about 60 minutes" is displayed, S6 is "Out of order" is displayed, and S7 is "Elevator is closed due to an earthquake."
"Cannot be used until inspection is completed" is displayed.

- The indicator 7b on the first floor is different from other indicator lights in that it is a lamp type, and is therefore driven via a lamp driver 07b with a decoding circuit. Here, it is preferable to reduce the number of wires and standardize the wiring with the terminal device 4b by incorporating the pump driver otb into the interior of the indicator 7b. Further, it is desirable for ease of use that some of the output circuits 419, especially T421 and T422, be capable of driving lamps.

FIG. 6 is an operation flow showing the overall operation of the microcomputer 100 of the elevator control device 1. It is activated by restarting the CPUIOI, and after initial processing, the transmission control process shown in detail in FIG. 7 is performed.

At this point, if there is an abnormal slave station, it will be detected, the failure rank and failure location will be determined in the control equipment failure detection process (C120), and the maximum level of failure will be determined in the control state determination process (C140). and run the driving method selection process (C150
) to comprehensively judge the situation, determine the driving method code, and perform permission command processing (C160) to realize a software system configuration that can command processing appropriate to the situation.

For example, if there is a failure in the network transmission control system, the function of this part may be deleted, the call control processing C520 may be switched to standalone operation, control of the information system may be prohibited, or the abnormality may be identified using graphical means. (For example, when waiting for the door to close, when switching to maintenance, or when opening the door on the floor of the manager's room, etc.)
An operation permission command is outputted by the alarm control processing C560 to perform control to notify by a display device installed in the car or the like.

Conversely, if there is an abnormality in the input/output terminal device 4a of the BIF, this slave station is disconnected and service is started. The occurrence of an abnormality, the floor of the abnormal slave station, and the part number stored in EEP ROM2O3 are sent to the terminal through control output processing 0180 and network transmission data input/output processing C400, allowing the center to respond appropriately and quickly. possible.

When the initial processing is completed, the processing from steps C300 to C190 is repeated at a cycle TH.

Generally, the startup control of these tasks and modules is performed by O8.
However, for convenience of explanation, idle processing (C185) is used here instead.

FIG. 7 is a detailed operational flow example of the initial processing of transmission control in the host, and is explained using the I10 transmission control relationship as an example.

When processing starts with C200, first D P RA M2O3
Test data (mode 1) is set in all areas in order to detect abnormalities in and related circuits. For example 801~SF
The addresses up to F are set sequentially in address order, and the final address CHKD (see FIG. 14(a)) is set to 01 (C'205). At this time, a diagnosis is made to see if there are any writing errors.

Next, on the master station 2 side, the contents of the lower address are copied to the upper address while rotating the contents to the right one bit at a time (9th
Figure-M2O3).

Check the result (C210).

If there is an abnormality and the master station 2 is not located, or if the master station 2 is abnormal and does not respond, a timeout (approximately 1 second) is determined in steps C220 and 0240, and the error code I0C is determined.
It sets ER1 and requests the above-mentioned software system to prohibit all high-speed driving from now on, and when a predetermined condition is satisfied, it decides to retry (C190).

For example, 5FF-
3QL and set SO2 to CHKD (C
215).

If it is normal, the O bit of 5TATUS (FIG. 14(a)) is set to "1".

Next, in step C245, basic specifications and transmission management specifications as shown in (b) are created based on similar tables provided inside the EEPROM 103.

Next, create highly common terminal specification data to be received by all slave stations and store it in table 5CTXS (C250)L,

In addition, in step C320, it is assumed that up to two times are normal, which is necessary when the period TM of the master station is somewhat longer than the period TH of the host, and the number of times step C330 is not limited to four times. do not have.

The process consisting of the next steps C382 to C394 is based on the data table 5IR that the master station 2 receives from each slave station and creates.

), and the cyclic processing from steps M2O0 to M2O3 is executed at a cycle TH.

The following points (1) and (2) are noteworthy in this example.

=31- ■ Error table 5IERW (shown in Figure 14(c))
o) The 7 bits of ~518RX(0) (this is set to "1" when the host determines that the terminal is unused or malfunctioning) are determined (M300) and transmission with the slave station is performed. Therefore, an idle process (M370) is provided to make it easier to determine the cause of a failure using a protocol analyzer or the like using transmission line 3.

■ If 4 bits of 5TATUS are "0" in the common data transmission (M2O3) and each terminal data transmission (Ma2O) section, the terminal specification table 5CTXS
-318TXS is transmitted, and if it is "1", the contents of control table 5CTXD-318TXD are transmitted.

Also, in step M410, SDN○ is updated (for example,
When the 4 bits of 5TATUS are ``ON'', 3 bits are set to ``1'', and when the 4 bits of 5TATUS are ``1'', the 5 bits of 5TATUS are set to ``1''.

Figures 10 and 11 show data transmission on the slave station side, where input/output terminals 4a to 4d' and 6° = 33- are all used in the same way, and 13 can be used in almost the same way except for door control. This is an operation flow showing a specific example of input/output processing.

First, in the initialization process (S100), the microcomputer 405 or 605 determines whether the small terminal or medium terminal is P14.
Initialize and read pins 0-3 of 06 and PI608 in a human-powered boat, and the read code is SF (small size).
, SE (medium size), or SD (not shown, the car input/output terminal unit W13 also serves as door control).

In order to ensure that the input circuit and PI will not be damaged even if the received instructions based on the terminal specification data are incorrect, the PI
A rationality check is performed in the data direction set section of the system, and if there is any doubt, the PI is set on the input side, which is the safe side.

Next, the period TS (
In order to ensure a cycle shorter than the minimum cycle TM of the master station,
The period shall be shorter than the required period. ) to perform circular processing. Here, S 300 is input/output covered definition processing based on terminal specification data, which sets transmission code to ST, data direction of PI, etc.
543 is a blinking control process for the elevator car position and full light, etc.; 5420 is a response light lighting process (detailed operation is shown in FIG. 15);
0 is a process of determining whether or not to output the indicator 7b as a code signal, S540. S550 is a process of outputting lighting data to the PI, for example, PI 411, in accordance with the I10 specifications for small stations (shown in FIGS. 12(e) and 12(f)).

Next, a diagnostic pulse is output (S600) to perform a failure diagnosis such as whether the received data is unreasonable or all calls are always "1" (5700), and check the transmission buffer. Create code (sum data etc.) (S
800) j,, cycle T in idle processing (S850)
Keep S. Note that this idle processing can be performed using, for example, a hard timer that changes every 10 m5 or a received iRQ.
This can be done by checking the number of times.

Note that when the slave station is delivered or when the hardware of the slave station is replaced, terminal N is transferred in steps 8250 to 5260.

Enter the code and enter EEPROM414 or 614.
You need to write to. At this time, in order to binarize what has been input into IND and display it, store it in the table that receives slave station N○ as the car position (S270) and display it.
(S550).

On the other hand, another method for setting the slave stations is to prepare four vacant input terminals and provide wiring to distinguish the Hall slave stations.

Figure 11 shows the wake-up pulse (1 byte transmission time,
Here, 1 is activated when data is received from the master station after receiving a pulse that lasts "1" for 176 μs or more.
This shows a specific example of the operation flow of the interrupt processing program, and its role has been described above, so the explanation will be omitted.
