FIG. 2 is an operation flowchart of the elevator controller. The operation of the elevator controller will be described with reference to this figure. When the power of the elevator controller Z1 is turned on, the initial clear of the ram ZR1 and ACI are performed in step S100.
Initial processing of ZA1 and ZA2 is performed. Next, in step S200, an input / output process for a car call and a hall call is performed, and other general data input / output is performed in step S300. In step S400, the trouble display code is displayed on the in-car display CIND1. Step S500
Then, the driving direction of the car is determined according to the hall call and the car call, and the traveling control of the car is performed in step S600. In step S700, it is determined whether the display content of the display currently connected to the hall terminal should be updated. If it is to be updated, the display data for the hall display is selected and processed in step S800 and set in the transmission table for common transmission to all hall terminals in step S810.

Next, the hole and car input / output processing in step S200 of FIG. 2 will be described with reference to FIG. In step S201, first, IND data for hall display, which is common to all hall terminals, is transmitted. After the transmission is completed, a transmission process with the car terminal CLA1 is performed in step S202. The transmission processing result with the car terminal CLA1 is confirmed in step S203, and if normal, the car communication error flag is cleared in step S204. If it is abnormal, the car communication error flag is turned on in step S205. Next, step S2
Transmission processing with the hall terminals H1 to H4 is performed in 06, the transmission processing result with the hall terminals H1 to H4 is confirmed in step S207, and if normal, the hall communication error flag is cleared in step S208. If it is abnormal, step S2
At 09, the hall communication error flag is turned on. Next, in step S210, the car communication error flag is checked, and if it is turned on, it is checked in step S211 whether or not the initial specification transmission is necessary. If necessary, step S21
In step 2, the car terminal initial specifications are transmitted to the car terminal CLA1. If the determination result in step S210 is 0, the hall communication error flag is confirmed in step S213, and if it is turned on, it is confirmed in step S214 whether or not the initial specification transmission to the hall terminal is necessary.
Hall initial specifications in 5 all hall terminals H1-H
Send to 4. Data indicating a storage-permitted terminal is provided in this initial specification, and it is determined whether or not the received hall terminal stores the data. As a result, each hall terminal can be initialized separately, and the processing time can be significantly shortened as compared with the case of individually transmitting the initial specifications. Also, depending on this initial specification setting, different processing can be performed even if the same data is received by all hall terminals.
In the present embodiment, the hall guidance device displays the same display on all floors, so that common display data is transmitted to all hall terminals. However, there may be a situation in which the guide display is not desired to be displayed on the non-stop floor, and there may be a case where a different guide display is desired. In such a case, the hall terminal initial specification transmission process is performed at the timing shown in step S2125 of FIG.

More specifically, two kinds of initial specifications for the hall terminal are provided, one for turning off the guidance display and the other for outputting the guidance display. For the service floor, the initial specifications transmission table for guidance display output (1) (2) As the reception and storage permission data, the data obtained by converting the service floor information into binary data is set as shown in FIG. When this initial specification transmission is performed, it is received by hall terminals other than the service floor. However, on the hall terminal side, the reception storage permission data (1) and (2) in the received initial specification table must match the own station NO. If it does not store it, if it matches, it stores it, and when the display data is received next time, the guide display will be performed. As the initial specifications for turning off the guidance display, the inverted reception storage permission data (that is, nonstop floor data) is set in the initial specification transmission tables (1) and (2). This initial specification is received and stored only in the hall terminal on the non-stop floor, and the guide display is not performed even if the display data is received. When it is desired to display the guidance again, the initial specifications for guidance display output may be stored.

Next, referring to FIG. 4, step S300 of FIG.
Details of the guide device display data creation processing will be described. In this embodiment, an example in which a car position is displayed on the left two digits and a driving direction is displayed on the right one digit by an arrow with a three-digit display will be described with reference to FIG. In step S310, as the car position display processing, display data is created from the current car position. As an example, if the car is driving between the 2nd and 3rd floors toward the 3rd floor, and the car is located between the 2nd and 3rd floors and the 2.5th floor, The non-displayed display data is read out from the EEPROM (which can also be a storage device such as an optical disk), and the data of columns 1 to 8 is set in the output work 1. Since the display contents of the second digit are scrolled from the second floor to the third floor, the display data of "2" and "3" of the display data are read from the EEPROM and the 3rd to 6th columns of the display data of "2" are read. Cut out the data and set it in the 1st to 4th columns of the output work. Next, the data of the 1st to 4th columns of the display data of "3" is cut out and the data of 4th to 4th of the output work is cut out.
Set in the 8th row. Since the display contents of the 3rd digit indicates "↑" in the driving direction, the display data of "↑" is read from the EEPROM and the data of the 1st to 8th columns is set to the output work. 1 when the 3rd digit output work creation process is completed
Set the contents of the output work of 3 digits to the transmission table. As a result, the display contents of the display are as shown in FIG.

Next, referring to FIG. 5, step S400 in FIG.
The details of the trouble code display process will be described.
In step S410, it is determined whether maintenance operation is in progress. If not during maintenance operation, normal display processing is performed in step S435, the display data created in steps S320 to 330 is set in the transmission table to the car terminal in step S440, and the process returns to the main routine. In step S420, it is determined whether the open button and the close button in the car are simultaneously pressed. If they are pressed, the trouble code is converted into display data in step S430. Next, step S440.
The process returns to the main routine in which the display data generated in step 3 is set in the transmission table to the car terminal. If it has not been pressed, display data of no display is generated in step S434, and the process proceeds to step S440.

Next, the regular processing on the side of the hall terminal will be described with reference to FIG. After the power is turned on, the own station determination process is performed in step S900. As shown in FIG. 1, the one-touch microcomputer HC1 or CC1 of the hall terminal H1 or the car terminal CLA1 is a dip switch DP1 or DP5.
The local station number set in step 1 is read to determine whether the local station is a car terminal or a hall terminal. Next, in step S905, the output circuit is reset to prevent erroneous lighting of the hall button response light or the like. In step S910, the reception process of the hall spec transmission or the car spec transmission, which is transmitted from the elevator control device Z1 via the common transmission line L1 or L2, is performed until it is completed. When the reception is completed, the initial of the own station is performed by the hall or car specification transmission received in step S920. Next, step S
At 930, the presence or absence of data in the reception table is confirmed, and at step S940, the validity of the reception data is checked by a sum check. More specifically, FIG. 11 shows an example of hall or car terminal output processing when n bytes of data is transmitted from the elevator controller Z1. The total sum of the data set in the transmission tables (0) to (n-1) is set in the transmission table (n). In the hall or the car terminal, the total sum of the data of the reception tables (0) to (n-1) is compared with the data value of (n), and if they match, it is determined that the reception is OK, and in step S950, the contents of the reception table. To the output table. If it is determined that the reception abnormality has occurred, it is determined in step S941 whether the reception abnormality has continued for a predetermined period. If it has continued for the predetermined period, all reception data is cleared in step S942, and data output to the output circuit is stopped. . In step S960, the data of the hall call or car call button and the response light is input / output processed. For call input, the value of the port to which the button is connected is read and copied to the input table.
In the response lamp lighting process, the data in the output table is set in the port to which the response lamp is connected. In step S970, the display HIND1 or CIND1 installed in the hall or the car is lit. In the present embodiment, an example of an 8 × 8 dot LED × 3-digit indicator will be described with reference to FIG. The data values of the output table are set in the indicator output port with the data values from the 1st column to the 8th column at intervals of 4ms. The output width to this port is set to 4 ms (this output width does not cause flicker to human eyes and is effective from the viewpoint of hardware life).

FIG. 7 shows a detailed display flow of the display of the hall or car terminal. In step S1100, 3 ms idle processing is performed. Next, in step S1101, the first output display data string is set to 1. Next, step S1
At 102, output data (CDATA) is set to 0 to prevent erroneous output to the display. In step S1110, the data of the n-th column of the first digit is set in the output port of the first digit.
In step S1120, the data of the nth column of the second digit is set in the output port of the second digit. In step S1130, the data of the 3rd digit nth column is set to the 3rd digit output port. Next, in step S1135, after idle for 0.5 ms, CDATA =
Output n. Next, in step S1140, the value of n is incremented. Next, in step S1150, idle processing is performed for 4 ms, and then in step S1160.
It is determined whether or not the value of n exceeds 8. If the result is 8 or less, an idle process of 3.9 ms is performed in step S1150, and a loop process is performed to step S1102. Next, the interrupt processing flow on the side of the hall terminal will be described with reference to FIG. Normally, the hall terminal performs the regular processing shown in FIG. 7, but when data is transmitted from the elevator control device, the reception processing is performed by the interrupt processing. In step S1000, as the header reception processing, only the first 1 byte (header) of the data transmitted from the elevator control device is received. In step S1010, whether or not the header is data to be transmitted / received by the local station is compared with the local station No. If it matches the own station number, all the data transmitted in step S1020 is received. Next in step S103
At 0, transmission processing of hall call data and the like is performed to the elevator control device. The determination result in step S1010,
If it is determined that the received / transmitted data is not received by the local station, it is determined in step S1011 whether the received data is common reception data that is received only by the local station. Otherwise, the subsequent data is not received and the interrupt processing is ended.

As described above, according to the embodiment of the present invention, the display data is stored in the elevator control device, and after this display data is processed, it is transmitted to the guide device via the common transmission line to display the display data. By refreshing the display based on the display data on the received guide device side, if you want to change the guide display, you only have to change the stored display data in the elevator control device in the local machine room,
There is no need to change the guide device installed at each landing. In addition, it is possible to provide an elevator control system that can omit specification design depending on the destination such as when the floor display is reset at the site.

[0016]

As described above, according to the present invention, since there is no need to have a storage means and a processing means for display data such as characters, external characters, and figures in the hall or car guide device, the cost of the guide device is reduced. The display data can be easily changed and added in the machine room, so it is possible to easily change the content of the guide display on site, so the specification design for the guide display by the customer can be omitted. .
