〔Example〕

The present invention will be described in detail below with reference to the embodiments shown in FIGS.

FIG. 1 is an overall configuration diagram showing an embodiment of an elevator control device according to the present invention, which is applied to a hydraulic elevator. In FIG. 1, 1 is a control device, 2 is a motor, 3 is a hydraulic pump, 4 is a solenoid valve, 5 is a cylinder, and 6
Is a plunge, 7 is a pulley, 8 is a rope, 9 is a basket, 10 is a tank, 11 is a communication line, 12 is a hall call button, and a call from the hall call button 12 is a cable 24 in the tower.
When the call is given to the elevator control device 1 via the, the operation control circuit 17 determines the relative position between the floor where the call is generated and the elevator car 9, and if the call is above the car position, the operation control circuit 17 To speed control circuit 18
A rising driving command is given to the. In the speed control circuit 18,
When a rising operation command is given, a start command is given to the motor 2 via the input / output circuit 19, and a valve opening command is given to the solenoid valve 4 via the input / output circuit 19 as well.

If the call is below the car position, the operation control circuit 17 gives the speed control circuit 18 a descending motion command. In the speed control circuit 18, when a descending command is given, a valve opening command is given to the solenoid valve 4 via the input / output circuit 19.

When the motor 2 is driven by the command from the elevator controller 1 and the hydraulic pump 3 is driven, the pressure of the oil sent from the hydraulic pump 3 to the solenoid valve 4 increases. Therefore, when a valve opening command is given from the control device 1 to the solenoid valve 4, the oil that has passed through the solenoid valve 4 is sent to the cylinder 5.
The plunger 6 is pushed up by the rise of the hydraulic pressure in the cylinder 5, and the car 9 connected to the rope 8 hung on the pulley 7 rises along the guide rail 23. When a stop command is given from the control device 1 to the motor 2 and the electromagnetic valve 4, the supply of oil to the cylinder 5 is stopped, so that the car 9 is also stopped.

When a valve opening command is given to the solenoid valve 4, the oil in the cylinder 5 passes through the solenoid valve 4 and escapes to the tank 10, so that the plunger 6 and the pulley 7 descend as the hydraulic pressure in the cylinder 5 decreases. Rope 8 hung on this
The car 9 connected to is also lowered.

The above is a brief description of the elevator ascending / descending operation.

Now, when the elevator is delivered to the site, various adjustments will be made to perform appropriate control for each delivery destination. The adjustment items include actual measurement of floor pitches in the local building called floor height measurement operation, measurement of car position correction data to ensure the accuracy of elevator landing level, and control by changes in car load. Bias value and gain value measurement for load detection or oil pressure detection to reduce the effect on characteristics,
Measurement of bias value and gain value used for start-up compensation in order to reduce shock at start-up, and measurement of bias value and gain value for oil pressure detection to reduce the influence on control characteristics due to oil temperature and changes, etc. There are many types.

Therefore, in the embodiment of the present invention, as shown in FIG. 2 (a), these adjustment items are assigned corresponding selection numbers in advance according to the adjustment procedure, and are made to correspond to each other, and the program according to the number is activated. did. With such a configuration, various adjustment procedures are clarified, and the effect of the adjustment work is enhanced. Although the selection number is assigned in this embodiment, a symbol or the like that can distinguish them from each other may be assigned.

The input of this number is performed by the input device 20 of FIG. Further, this input may be made by inputting from a distant communication as shown in the input device 26 of FIG.

Next, FIG. 3 shows a process chart when the process inside the control device 1 of FIG. 1 is realized by a microcomputer.

As shown in FIG. 3, in the embodiment of the present invention, the program start synchronization is divided into two types, T1 and T2, and those requiring high-speed processing are those requiring high-speed processing in the T1 synchronization of FIG. 3 (a). Those not to be started were started in the T2 cycle of FIG. 3 (b). In step 100, an operation control process A for handling car calls, hall calls and the like is performed. In step 200, a speed control process A ′ is executed which is in charge of processes such as issuing a start command to the motor 2 and a start command to the solenoid valve 4. Step 30
At 0, various measurement detection processing such as load detection is performed. At step 400, a maintenance control process is performed which is in charge of determining the input from the input device 20.

On the other hand, the start cycle of the T2 cycle is longer than that of the T1 cycle.
I do. In step 600, a speed control process B ′ is in charge of copying control constants from ROM (read only memory) to RAM (random access memory). In step 700, various constants of electrically rewritable nonvolatile memory (Electrical Erasable Program) are used.
mable Read only Memory, abbreviated as EEPROM below)
A maintenance control process B ″ that is in charge of writing to the device is performed.

Now, when the installation of the elevator to the delivery destination is completed,
Conventionally, a floor height measuring operation for measuring each floor pitch of a building of a delivery destination as shown in JP-A-57-149271 is performed.

The embodiment of the present invention is performed as follows. That is, as shown in FIG. 2 (a), the floor height measurement is an element to be adjusted first after the elevator is installed, and therefore, the selection number 1 is assigned. Therefore, the input is made from the input device 20 of FIG. 1 or from the communication input device 26 (hereinafter collectively referred to as the input device) by communication from a distant place.

The entered selection number is the same as the step 40 in FIG.
0, that is, it is processed by the flow chart shown in FIG. First, in step 4005, a process of fetching the input from the input device 20 or 26 of FIG. Next, in step 4010, the boot designation and additional information are read from the boot management table shown in FIG. 2A according to the input number. In this case, since the selection number 1 is selected, "program activation" is selected for activation designation and "floor height table measurement writing program" is selected for additional information. Therefore, step 4020
If the start designation in step S30 is a flag set, the answer is no (NO), so the process proceeds to step 4030. If the start designation is a program start, the determination is yes (YES).
Therefore, the procedure proceeds to step 4110, and the program shown in the additional information column is started, that is, the floor height table is measured and the writing processing to the EEPROM is performed, and then the other maintenance control processing is performed in step 4130. A series of processing ends. In this way, once the number is entered, a series of operations from the process of measuring the floor height value to writing to the EEPROM is automatically performed, so the workability in field installation can be improved.

With the above processing, the elevator installed locally can be operated in the high speed mode.

This is the end of the adjustment assigned the selection number 1.

Therefore, next, as shown in FIG. 2A, the load detection zero point adjustment is performed. This is done as follows. First, the inside of the car is put into an unloaded state, and the input device 20 or 2 shown in FIG.
When the selection number 2 is input by means of step 6, tonight, in step 4010 of FIG. 4, "set of flags" is designated as the activation designation from the activation management table of FIG. 2 (a) and "load detection zero point adjustment flag ( Hereinafter, referred to as WBAJST flag) ". Since the flag set or reset is selected for the start specification, steps 4020 to 4 are selected.
In step 120, the flag is set in the additional information column, that is, the WBAJST flag is set. In step 4130, other maintenance control processing is performed, and the processing ends.

In the above processing, since the WBAJST flag is set, the load detection zero point adjustment processing is performed in step 7000 of the program started in the T2 cycle of FIG. 3 (b). The details will be described with reference to FIGS. 5 and 6.

In FIG. 5, since the WBAJST flag is set in step 7010, the process proceeds to step 7020, the safety check relay is turned off, and the elevator is prohibited from traveling. By doing so, it is possible to avoid the danger of the elevator going out of control when writing to the EEPROM. Next, at step 7030, the input from the differential transformer 27 for load detection shown in FIG. 1 is substituted into EWK which is a work for writing EEPROM data.
In step 7040, the address (iWBAJST) of the load detection zero adjustment speck is substituted into the work AWK for designating the EEPROM write address. In Step 7050,
One piece of the number of prints is substituted into the work DWK for designating the number of pieces of print data, and the process proceeds to the EEPROM write processing of step 7060. The details will be described with reference to FIG.

In step 6110 in FIG. 6, the state of the safety check relay is checked. In this case, since the safety check relay is turned off at step 7020 in FIG. 5, the process proceeds to step 7120 in FIG. Step 712
At 0, since DWK = 1, the process proceeds to step 7125. In step 7125, N = 0 is set in order to set the pointer indicating the storage location of the burning data at the head. In step 7130, interrupt masking is performed. Next, in step 7140, the data at the address designated in the work AWK is erased. Next, in step 7145, EE
The PROM burning signal is monitored, and when the burning is completed, the process proceeds to step 7150. At step 150, the contents of the EWK are printed on the address specified in the work AWK. Next, in step 7150, the burning signal is monitored in the same manner as during erasing, and the burning, that is, the work A
Burn the contents of the work EWK to the address specified in WK. In this case, when the input from the differential transformer 27 shown in FIG. 1 is completely burned into the storage location of the load detection adjustment speck, the process proceeds to the next step 7160 to cancel the interrupt. The reason for writing after erasing is due to the characteristics of the EEPROM. In addition, the monitoring of the in-burning signal is performed because the time required for erasing and writing the EEPROM is about 10 ms, which is extremely long compared to the time required for a general RAM, and the EEPROM being written during this period. This is to prevent that the contents of the data cannot be read correctly when it is read, so that the data in the EEPROM is read during writing, which may lead to a runaway of the microcomputer. Further, the masking processing of the interrupt in steps 7130 and 7160 is also for preventing access to the EEPROM being written by the interrupt. Note that, in the present embodiment, interrupts are collectively prohibited for erasing and writing, but interrupts may be temporarily canceled between steps 7145 and 7150, and then interrupts may be masked again immediately. This way,
It is possible to minimize the time required for EEPROM burning.

Further, the description of the flow chart shown in FIG. 6 will proceed. Step 7170 is for burning data storage address (EWK) when plural burning data locations are designated.
(N)) and destination address (contents of work AWK)
Process to update. In step 7180, it is checked whether or not the designated number of prints have been completed. If not, the process returns to step 7130. In this case, since the designated number of prints is one, a series of processing is ended.

Thus, the processing of step 7060 of FIG. 5 is completed, and the processing proceeds to step 7070, in which the WBAJST flag is reset and the input selection number is reset.

The above is the description of the process of performing the load detection zero point adjustment by inputting the selection number 2 from the input device 20 or 26 in FIG. 1, and the adjustment assigned the number 2 is finished.

Now, by inputting the selection number 3 from the input device 20 or 26 of FIG. 1, the start compensation bias (UP
Side) adjustment. In this case, step 401 in FIG.
In 0, since the selection number 3 is selected, according to the activation management table shown in FIG. 2A, the activation designation is the data input request, and the additional information is the activation compensation bias (UP).
The spec (i65WUP) is selected. In this case, since the start designation is a data input request, steps 4020, 40
Proceed to step 4045 via 30, 4040. In step 4045, it is judged whether or not the data is input from the input device. If the data is input, the process proceeds to step 4050, and the data input from the input device is substituted into EWK.
In step 4060, the address indicated in the additional information column, that is, the activation compensation bias (UP) spec address (i65WUP) in this case is substituted into AWK. next,
In step 4070, the number of data 1 is assigned to DWK, and in step 4080, the address assigned to AWK is EE.
It is determined whether it is the PROM area. As shown in FIG. 2A, the address that can be registered in the additional information field may be a RAM area such as a hydraulic external designated value (DXTWK) corresponding to the selection number 13. This is because. In this case, since it is the EEPROM area, the safety check relay is turned off in step 4095, the process proceeds to step 4100, and the contents assigned to EWK are written in the AW.
The address indicated by K is printed. That is, whether the input data is useless or not, the start compensation bias (UP) spec (i65WUP) is printed. This detail is performed by the processing of FIG. 6 specified in the writing processing of the load detection zero adjustment speck. Next, step 4110.
In step 4130, the selection number is cleared, and in step 4130, a series of processes is completed.

As described above, when the writing of the start compensation bias (UP) spec is completed, as shown in FIG. 2 (a), the selection number 3 is input from the input device 20 or 26 of FIG. Bias (DN) spec writing is performed. As shown in FIG. 2A, since the activation designation corresponding to the selection number 4 is a data input request, this is performed in the same manner as the writing of the activation compensation (UP) specs corresponding to the selection number 3. .

When the adjustment up to this point is completed, this time the weight is loaded on the car and the load is adjusted to full load. When the car is fully loaded, the input device 20 or 26 shown in FIG.
The selection number 5 is input from and the load detection gain is adjusted. This is the same processing as the load detection zero point adjustment. The details will be described below with reference to FIGS. 1, 4, 2, and 7. When the selection number 5 is input, a step 4010 in FIG. 4 sets a flag for activation designation from the activation management table shown in FIG. 2 (a), and load detection gain adjustment flag WGAJST (hereinafter WGAJST) as additional information.
(Referred to as a flag). Hereafter, step 4020
Then, the process proceeds to step 4120 to set the flag shown in the additional information column, that is, the WGAJST flag is set. In step 4130, other maintenance control process is performed, and one process ends.

In the above processing, since the WGAJST flag is set, the load detection bias adjustment processing is performed in step 7200 of the program started in the T2 cycle shown in FIG. 3 (b). The details will be described with reference to FIGS. 5 and 7. Since the WGAJST flag is set in step 7210 of FIG. 7, the operation proceeds to step 7220.
Turn off the safety check relay. Next, in step 7240, the differential transformer 27 for load detection shown in FIG.
Substituting the gain value calculated by using the input from iWBAJST into EWK, which is the work for writing EEPROM data, and in step 7250, the address of the load detection bias adjustment spec (iWGAJST is used to specify the writing EEPROM address). Substituting it into the work AWK, and in step 7260, substituting one print number into the work DWK for instructing the number of burn-in data, step 72
Proceed to 70 EEPROM write processing. Details thereof have been described in the description of the load detection zero point adjustment, and therefore will be omitted. Step 72
At 80, the WGAJST flag is reset and the selection number is reset, and the series of processes is completed.

Next, floor adjustment speed command zero adjustment is performed. First, before that, an input processing method from the stop position fine adjustment position detectors 14 and 16 in FIG. 1 will be described. The input process is performed by step 3000 in FIG. The details will be described with reference to FIG. First, in step 3010, the input from the fine adjustment position detector A14 of the stop position shown in FIG. 1 is fetched into XMAWK. Next, step 302
At 0, it is judged whether or not the value fetched in XMAWK is normal, and if it is an erroneous input, the process proceeds to step 3030, and the error flag (ERM1) is set.
If there is no error, the process proceeds to step 3040 and the input from the fine adjustment position detector B16 of FIG. 1 is fetched into XMBNWK. In step 3050, it is determined whether or not the value previously captured in XMBWK is normal, and if it is an incorrect input, in step 3060 an error flag (ERM
The set process of 2) is performed. If the input is normal, the process proceeds to step 3070, and it is determined whether the error flag (ERM1 or ERM2) is set.
If the error flag has been set, step 30
At 95, an error flag (ERM0) is set, and a series of processing is completed. If it is confirmed in step 3070 that the error flag (ERM1) or the error flag (ERM2) is not set, step 308
0, the input values fetched in XMAWK and XMBWK, respectively, are substituted into the control memories XMA, XMB, and in step 3090, the error flags ERM0, ER
Reset of M1 and ERM2 is performed, and a series of processing is completed. With such a configuration, it is possible to create a system that does not malfunction with respect to an erroneous input from the detection device.

The above is the position detector 14, 1 for fine adjustment of the stop position in FIG.
6 is a description of an input method from 6.

Here, the process returns to the floor adjustment speed command zero adjustment. This adjustment is done with the elevator car in line with the level. Next, floor adjustment speed command zero adjustment is performed. When the selection number 6 is input from the input device 20 or 26 of FIG.
In step 4010 of FIG. 4, a set of flags for activation designation from the activation management table shown in FIG. 2 (a) is used as additional information, and floor adjustment speed command zero adjustment flag MVZA is added.
Select JST (hereinafter referred to as MVZAJST flag). Less than,
The process proceeds to step 4120 through step 4020, and the flag set processing indicated in the additional information column, that is, MVZAJST
The flag is set, other maintenance control processing is performed in step 4130, and the processing ends.

In the above process, since the MVZAJST flag is set, the floor adjustment speed command zero adjustment process is performed in step 7300 of the program started in the T2 cycle shown in FIG. 3 (b). The details will be described with reference to FIGS. 5 and 9.

In FIG. 9, in step 7310, since the MVZAJST flag is set, step 7320 follows.
Turn off the safety check relay. Next, in step 7330, the difference between the previously obtained XMA and XMB is obtained, and the substitution processing to the EWK which is the work for writing EEPROM data is performed. In step 7340, the address (iMVZAJST) of the floor alignment speed zero adjustment spec is substituted into the work AWK for designating the EEPROM writing address. In step 7350, the number of images to be burned is assigned to the work DWK for designating the number of images to be burned, and step 7
Proceed to 360 EEPROM write processing. The details are shown in FIG. 6, but since they have already been described, the description thereof will be omitted. In this process, the floor adjustment speed command zero adjustment spec is written. Next, in step 7370, reset processing of the MVZAJST flag and clear processing of the selection number are performed, and a series of processing is ended.

Next is the upper position correction writing, which is performed as follows. First, as shown in step 10 of FIG. 10, the UP (up) operation is performed toward the elevator middle floor, and the measurement operation of the upper car position correction data is performed. The signal flow during the measurement operation will be described again with reference to FIG. The rotary encoder 22 mounted on the car 9 generates a pulse proportional to the moving distance of the car 9 and is inputted to the speed control circuit 18 and the maintenance circuit 21 via the input / output circuit 19 through the tail cord 11. .
When the car 9 rises and the elevator is about to land, the position detector A14 for fine adjustment of the stop position, the position detector 15 for detection of the door opening permitted zone, and the fine position detector B16 of the stop position are activated. These signals are successively passed through the tower shield 13 and these signals also pass through the tail cord 11 and the input / output circuit 19
It is input to the speed control circuit 18 and the maintenance circuit 21 via the.

Here, the processing in the maintenance circuit 21 will be described with reference to FIGS. 3 and 11 to 14. FIG. 11 is a flow chart for measuring the first position correction data used for the car position correction or the like at the time of floor passing or landing using the position detector for detecting the open door permission zone. At step 2010, the input from the door open permission zone detection position detector 14 is determined,
If there is no such input, that is, in FIG. 1, if the door open permission zone of the car 9 has not been reached, the process proceeds to step 2012, 0 is substituted into the position detector correction WK1, and a series of processing is ended. . On the other hand, in step 2010, when the input from the door open permission zone detection position detector 14 is detected, that is, when it is determined in FIG. 1 that the car 9 has risen to reach the door open permission zone, Immediately proceed to step 2014, and if it is confirmed that the vehicle is traveling upward, proceed to step 2016 and add the displacement (per program starting cycle) obtained by processing the input from the rotary encoder 22 to the value of the position detection correction WK1. Then, a series of processing is ended.

When the elevator stops in the door open permission zone, the series of processing is terminated via steps 2010, 2014 and 2018. At this time, the position detector correction WK1 contains the distance moved by the position detector 15 for detecting the door opening permission zone from when the position detector 15 crosses the inside of the tower barrier plate 13 until the elevator stops.

FIG. 12 is a detailed flow chart of the passing floor correction amount measuring process shown in step 2100 of FIG. 3 (a). For this purpose, the position detector A14 for fine adjustment of the stop position and the position detector B16 are used. In step 2110, it is judged whether or not there is an input from the position detector A14 for fine adjustment of the stop position.
Proceeding to step 14, in step 2114, it is judged whether or not there is an input from the position detector B16 for fine adjustment of the stop position,
If not, go to step 2112, if there is, step 2116
Go to. In other words, in steps 2110 and 2114, it is determined whether or not the force of the fine position detector A14 and the position detector B16 for fine adjustment of the stop position are both present, and if they are not present, the process proceeds to step 2112 to correct the position detector. WK
Substitute 0 for 2 and proceed to step 2116 if both are present. In step 2116, it is determined whether or not the elevator is traveling upward, and if it is traveling upward, in step 2118 the value from the rotary encoder 22 is processed to obtain the value of the position detector correction WK2 (program The displacements (per activation cycle) are added, and the series of processing ends. Elevator is out of level (at this time WK2 is 0)
When the inputs of the fine adjustment position detector A14 and the position detector B16 of the stop position both stop within a certain range, a series of processing is terminated via steps 2110, 2114, 2116, 2118.

Therefore, at the time when the elevator is stopped, the elevator is stopped after both the position detector correction WK2 is input with the position detectors A and B (14 and 16 in FIG. 1) for fine adjustment of the stop position. The distance to will be maintained.

FIG. 13 is a detailed flow chart of the step 2200 of FIG. 3 (a), which is a flow chart for determining whether or not the fine adjustment of the stop position is necessary from the input of the position detector for fine adjustment of the stop position. . Stop position fine adjustment position detector A,
If both B (14 and 16 in FIG. 1) are input, the process proceeds to steps 2110 and 2214 and then to step 2116.
Set the position detector status flag for fine adjustment of stop position.
On the other hand, if at least one of the inputs of the stop position fine adjustment position detector A or B is not present, step 2210
From step 2212 to step 2212, or from step 2210 to step 2214 and then to step 2212. At step 2212, the stop position fine adjustment position detector state flag is reset.

That is, in the flow chart processing shown in FIG.
Position detector for fine adjustment of stop position depending on whether the elevator is in a range that requires fine adjustment of stop position (range where the landing level is out of order) or a range that does not require fine adjustment (appropriate range of landing level) Reset and set status flags respectively.

FIG. 14 is a detailed flow chart of the car position correction amount measurement state detection processing shown in step 2300 of FIG. 3 (a), which shows whether or not the measurement of the first and second car position correction data is completed. Perform determination processing.

Consider the case where the elevator travels from one floor to the middle floor according to step 10 in FIG. In the state where the elevator is stopped on the floor where the elevator is located and immediately before the ascending operation, the elevator is in the zone where the door can be opened, and therefore the input of the door open permission zone detector can be obtained. Therefore, from step 2310 to step 2320. move on.
At step 2320, the upper car position correction amount measurement status flag is not set, so the routine proceeds to step 2318,
Reset the upper car position correction amount measurement complete flag,
A series of processing ends. Next, the elevator starts ascending traveling in response to the ascending operation command and exits the zone where the door can be opened. With this operation, there is no input to the open-door permission zone detector, so the routine proceeds from step 2310 to step 2316, then step 2314 to step 2316, where the upper car position correction amount measurement completion flag is set, and the series of processes is completed. .

Furthermore, the elevator arrives at the intermediate floor, which is the destination floor. When the elevator arrives at the middle floor, the input of the door open permission zone is obtained again, and therefore the process proceeds from step 2310 to step 2320. At step 2320, the upper synchronization position correction amount measurement state flag has already been set, so the routine proceeds to step 2322. While climbing, proceed to step 2328. Also, after stopping to level, step 2324
And proceed to step 2326. At step 2326, the stop position fine adjustment position detector state flag is determined. If the elevator is stopped at an appropriate position, the flag is on as described in the explanation of FIG. 13, so the procedure proceeds to step 2328, and the upper car position correction amount measurement state flag is held, A series of processing ends.

This completes the measurement of the upper car position correction data shown in step 10 of FIG.

Therefore, next, the operation shown in step 11 of FIG. 10 is performed. That is, the upper car position correction data is written to the elevator control device by inputting the selection number 9 from the input device 20 or 26 of FIG.

Next, the floor alignment adjustment zone is set. This is done with the elevator car shifted to a level where floor alignment operation is performed. By inputting the selection number 7 from the input device 20 or 26, the same processing as the setting of the floor adjustment speed command zero adjustment speck is performed by the processing shown in FIGS. 4, 3, and 15.

In this way, the floor alignment speed command zero adjustment spec and the floor alignment adjustment zone spec burned in the EEPROM are performed using the step 2400 of FIG. 3 (a). The details will be described with reference to FIG.

16, in step 2410, the inputs XMA and XMB from the position detectors A and B for fine adjustment of the stop position obtained by the flow chart in FIG. 8 and the floor alignment already burned in the EEPROM Using the speed command zero adjustment spec iMVZADJST, calculate how much the car shifts from the level and substitute it into WKM. Next, in step 2420, the state of the error flag ERMO is determined, and if ERMO is set, the series of processing is terminated. If not set, the process proceeds to step 2430 and the level shift is set first. It is judged whether or not the level is larger than the level given by the floor alignment adjustment zone spec iMZSET which has been reached, and if not, step 243.
In step 2, reset processing of the floor alignment permission flag (AM) is performed. The level difference is iMZS according to the judgment in step 2430.
If it is larger than ET, it is necessary to perform the floor alignment operation, so the flow proceeds to step 2434, and the floor alignment permission flag (A
Perform step M) and proceed to step 2440. In step 2440, it is judged whether the level is shifted upward, that is, the value of WKM is positive, or whether the level is shifted downward, that is, whether the value of WKM is negative, and if it is positive. For example, the processing proceeds to step 2442, and it is determined whether the input from the stop position fine adjustment position detector B is smaller than iMMAX, that is, the deviation of the landing level is determined,
If it is larger, the process proceeds to step 2444 to set an ascending direction floor alignment command, and the series of processes is completed. If it is not larger, the process proceeds to step 2446 to reset the ascending direction floor alignment command. If the value of WKM is negative in step 2440, the operation proceeds to step 2448, and it is determined whether the input from the stop position fine adjustment position detector A is smaller than iMMAK. A set-up command is set, the process proceeds to step 2452, which is not large, and a descending direction floor-set command is reset, and a series of processing is completed.

Next, the selection number 8 from the input device 20 or 26 of FIG.
Input and adjust the floor alignment speed command gain. This processing is carried out by the flow chart shown in FIGS. 4 and 15 in the same manner as the start compensation bias spec.

When the selection number 9 is entered, step 4010 in FIG.
Then, the program start is selected as a start command from the start management table of FIG. 2A, and the upper position correction value adjustment flag (ULAJST) is selected as additional information. Thereafter, the upper position correction value adjustment flag (ULAJST) is set in step 4120 via FIG. 4 and step 4020, the process proceeds to step 4130, and other processes are performed to end the series of processes.

As described above, when the upper position correction value adjustment flag (ULAJST) is set, the upper position correction value speck is written in step 7500 of FIG. 3B. The details will be described with reference to FIG.

In FIG. 17, in step 7510, it is determined whether or not the elevator is at the landing level based on the presence or absence of the input from the position detector for detecting the door opening permission zone, and if there is no input, it is incorporated in the input device 20 of FIG. In step 7558, an error is displayed on the display, etc., and in step 7556, the selection number is cleared and the upper car position correction flag (ULAJST) is cleared. If there is an input from the detector, that is, if the car is in the door open permission zone, it is determined at step 7530 whether the upper correction amount measurement state flag is set. This is because, in the step 2200 of FIG. 3 (a), that is, the flow chart of FIG. 13, there are both inputs from the stop position fine adjustment position detectors A and B in the determination of the steps 2210 and 2214. If so, then it is reset at step 2216 (if neither is reset at step 2212).

If the stop position fine adjustment position detection state flag is set in step 7520 of FIG. 17, that is, if the car 9 has stopped at the proper position, step 753
Go to 0. In step 7530, it is judged whether or not the upper car position correction amount measurement state flag (created in FIG. 14) indicating whether the measurement is completed is set. If not, the process proceeds to step 7540. In step 7540, the upper car position correction data adjustment flag (UL
AJST) is set. In this case, since the above flag is set, step 7
Proceed to 545 to turn off the safety check relay. In step 7550, a check is made to see if the first and second car position correction data have been created, and if it is confirmed that they have been created, then in step 7552 the contents of the first car position correction WK are assigned to EWK. Then, the contents of the second car position correction WK are substituted into EWK (1), and the address iULAJST of the upper car position correction spec (however, the first and second car position correction data specs are assumed to be continuous). ) Is substituted for AWK, and the data quantity work D
Substituting 2 for WK, the EEPROM writing process is performed in step 7554, the selection number and the upper car position correction data adjustment flag are cleared in step 7556, and the series of processes is completed. This is the end of the process corresponding to selection number 9.

The adjustment to be performed next is the adjustment of the lower position correction data corresponding to the selection number 10 shown in FIG. 2 (a), which is also the same as the adjustment of the upper position correction data. , First
0, FIG. 11, FIG. 12, FIG. 13, and FIG. 14, and the flow chart shown in FIG. 17, writing is performed by the flow chart in which the upper side is read downward.

After the above processing is completed, the oil temperature detection bias is adjusted next. The procedure will be described with reference to FIG. 18 (FIG. 18 shows a procedure operated by a human.) First, at step 20, the oil temperature in the tank 10 of FIG. 1 is measured by a thermometer or the like. Next, in step 21, it is determined whether the oil temperature range is appropriate. If the oil temperature is appropriate, in step 22 the elevator stop switch is turned off, and the safety check relay 25 in FIG. 1 is turned off. further
The EEPROM write enable switch 28 is turned on. Next, at step 23, the selection number 13 is input from the input device 20 or 26 of FIG. Then, in the flow chart shown in FIG.
5,4010,4020,4030,4040,404
Then, the process proceeds to step 5 to determine whether or not data is input from the input device. Therefore, when the previously measured oil temperature is input from the input device 20 or 26, step 4050 substitutes the input value into EWK. Further, in step 4060, the address indicated in the additional information column of FIG. 2A, that is, the oil temperature external designated value (DXTWK) corresponding to the selection number 13 in this case is substituted into AWK. Then, in step 4070, the number 1 is substituted into the data number work DWK, and the process proceeds to step 4080. Then, the address assigned to AWK, that is, DXTWK is shown in FIG. 2 (b).
As shown in FIG.
Proceeding to 90, the contents of EWK are substituted into the address indicated by AWK. That is, the oil temperature input from the input device is DX
Substitute in TWK. Next, in step 4130, other processing is performed and the input of the oil temperature is completed. Next, as shown in step 24 of FIG. 18, the selection number 12 is input from the input device 20 or 26 of FIG. 1 to perform the oil temperature adjustment bias adjustment. When the selection number 12 is input from the input device,
Similarly to the zero adjustment for load detection, the step 41 of FIG.
At 20, the oil temperature detection bias adjustment flag TRBAJST is set. Then, step 770 of FIG.
0, that is, in the determination of the TRBAJST flag in step 7710 of the flow chart shown in FIG. 19, the flag is on, so the routine proceeds to step 7720 and the DXT
It is determined whether or not WK (externally designated value of oil temperature) is within a proper range. If it is not proper, the process is ended. If it is proper, the process proceeds to step 7730, and the value of the input XTWK from the oil temperature sensor 29. Is determined to be appropriate, and a series of processing that is appropriate and terminated is ended. If appropriate, the process proceeds to step 7740, where the input value from the oil temperature sensor 29 is substituted into EWK, The address iXTB of the oil temperature input bias spec is assigned to AWK. Also,
Substitute 1 for the number of data works DWK. Next, step 7
At 750, the EEPROM is burned. Step 776
At 0, the value of the external input DXTWK of the oil temperature is substituted into EWK, the address iXTO of the oil temperature bias actual value spec is substituted into AWK, 1 is further substituted into the data number work DWK, and the flow proceeds to step 7770 to store the EEPROM data. After baking, at step 7780 the oil temperature bias adjustment flag TRBAJS
Reset T. When the writing of the oil temperature detection bias is completed in this way, the elevator stop switch is released at step 25 in FIG. 18 so that the safety check relay can be turned on, and the write enable switch is released to complete the series of processes.

Next, the oil temperature detection gain adjustment can be described with reference to FIGS. 4, 2, 20, and 21 in the same manner as the oil temperature detection bias adjustment. Here, the written bias and gain of the oil temperature are used as shown in the flow chart shown in FIG.

First, in step 3210, the input from the oil temperature sensor is substituted into XTWK, and in step 3220 it is determined whether or not there is an external input of oil temperature. Then, if there is an external input, the process proceeds to step 3230, the external input is substituted into the control work XT, and the series of processing is ended. On the other hand, if there is no external input, the process proceeds to step 3222. If the value of the input XTWK from the sensor is not within the proper range, it is regarded as an erroneous input, the process proceeds to step 3224, the error counter ERT is counted up, and control is performed at step 3226. Work X
Substitute 0 for T and terminate the process. On the other hand, if it is within the proper range, the process proceeds to step 3228, the control work XT is obtained by the following equation, and the processing is ended.

XT = (XTWK-iTB) / (α * iTG) + iTO (1) where α; coefficient A series of adjustment work is completed by the above procedure.

In this case, the request is the second
If it is sent in step 8030 of FIG. 3, a diagnostic process is performed in step 8110. This determines whether the data received at step 8090, that is, the various measurement adjusted data is within the proper range. Next, in step 8120, the diagnosis result of step 8110 is judged, and if the result is no, the process proceeds to step 8130 to create and output a report such as a list of items requiring readjustment. On the other hand, if the result is acceptable, the process proceeds to step 8140 to determine whether or not the received data includes an EEPROM burn-in permission signal, and if not, the series of processes is terminated.
