[Prior art]
2. Description of the Related Art An elevator maintenance tool is used as a means for collecting and analyzing data relating to an operating state of an elevator at the time of elevator failure or maintenance and inspection to determine whether there is an abnormality.
[0003]
FIG. 1 is a configuration diagram of an elevator maintenance system using a conventional elevator maintenance tool. Hereinafter, the configuration of the elevator maintenance system of FIG. 1 will be described.
[0004]
An elevator control operation device 11 is installed in an elevator for which data is to be collected. The elevator control operation device 11 has a function of outputting data (hereinafter, operation information data) corresponding to an operation processing instruction (hereinafter, operation information processing instruction) based on elevator control or operation. The elevator control operation device 11 includes an elevator interface 11a that controls data communication with the outside, an elevator control calculation CPU 11b that controls execution of operation information processing commands and data communication control, an elevator control calculation program 11c, and an elevator control calculation memory. 11d.
[0005]
The elevator interface 11 a of the elevator control arithmetic device 11 is connected to the maintenance tool 12. The maintenance tool 12 has a function of setting an operation information processing command to be executed by the elevator control operation device 11 and receiving and editing operation information data from the elevator control operation device 11. The elevator interface 11a is directly connected to the maintenance tool interface 12a in the maintenance tool 12. Both interfaces are compatible communication interfaces, and are capable of transmitting bidirectional data in synchronization with the operation cycle of the elevator control operation device 11. The maintenance tool 12 includes a communication interface memory 12b for storing operation information processing instructions and operation information data, a maintenance tool CPU 12c for setting operation information processing instructions, and editing operation information data, a maintenance tool program 12d, and a maintenance tool. It has a tool memory 12e and a display device 12f and an input device 12g as auxiliary devices. Here, the communication interface memory 12b is a dual port RAM, and can be accessed from the maintenance tool CPU 12c or the elevator control calculation CPU 11b. The maintenance tool CPU 12c is provided with a processing completion flag for identifying completion of access from the elevator control calculation CPU 11b.
[0006]
FIG. 2 is a workflow showing the operation of the elevator control arithmetic unit 11. FIG. 3 is a workflow showing the operation of the maintenance tool 12. The operation of the system shown in FIG. 1 will be described below step by step with reference to the drawings.
[0007]
First stage:
In the first stage, an operation information processing command is set in the maintenance tool 12. In the workflow of FIG. 3, the maintenance staff selects an operation information processing command to be executed by the elevator control arithmetic unit 11 via the maintenance tool program 12d of the maintenance tool 12 using the input device (step S301). Examples of the motion information processing command include call registration of an elevator car or a landing, access to a specific address of an elevator control calculation memory 11d of the elevator control calculation device 11, and the like. The motion information processing command selected in step S301 is stored in the communication interface memory 12b, but the maintenance tool CPU 12c checks whether the data stored in the communication interface memory 12b is readable. (Step S302). In step S302, if the elevator control calculation CPU 11b has already accessed the communication interface memory 12b, the access from the maintenance tool CPU 12c is impossible and the operation information processing command cannot be stored. Wait until the access is completed. When the access from the maintenance tool CPU 12c is possible, the maintenance tool CPU 12c stores the contents of the operation information processing command selected in step S301 in the communication interface memory 12b (step S303). In step S303, in addition to the operation information processing command, related data such as control parameters or address information is stored in the communication interface memory 12b as necessary. Next, the maintenance tool CPU 12c resets the processing completion flag in the communication interface memory 12b (step S304). By the operation in step S304, the communication interface memory 12b permits access from the elevator control arithmetic unit 11. Thus, the operation of the first stage is completed.
[0008]
Second stage:
In the second stage, the elevator control arithmetic unit 11 reads the set operation information processing command from the communication interface memory 12b of the maintenance tool 12, executes the command, and stores the operation information data in the communication interface memory 12b. In the workflow of FIG. 2, the elevator control calculation CPU 11b of the elevator control calculation device 11 checks whether a connection with the maintenance tool 12 has been established (step S201). In step S201, the elevator control arithmetic unit 11 constantly checks the connection with the maintenance tool 12 at the same timing as the arithmetic cycle. If the connection is confirmed in step S201, the elevator control calculation CPU 11b checks whether the data stored in the interface memory 12b of the maintenance tool 12 can be read through the elevator interface 11a ( Step S202). At this point, if the operation up to step S304 has been completed in the maintenance tool 12, the processing completion flag in the interface memory 12b has been reset, and access from the elevator control calculation CPU 11b is permitted. If the connection with the maintenance tool 12 cannot be confirmed in step S201, or if access from the elevator control calculation CPU 11b is impossible in step S202, the elevator control calculation CPU 11b ends the execution operation of the motion information processing command, The operation of step S201 is executed again at the timing of the next calculation cycle.
[0009]
In step S202, if the processing completion flag in the interface memory 12b is reset and the access from the elevator control calculation CPU 11b is possible, the elevator control calculation CPU 11b performs the operation stored in the interface memory 12b. The contents of the information processing command are read, and the motion information processing command is determined based on the elevator control calculation program 11c (step S203). The elevator control calculation CPU 11b that has determined the motion information processing command executes the corresponding motion information processing command based on the determination result, and stores the motion information data as the processing result in the interface memory 12b (step S204). For example, when it is determined that the motion information processing command is the process A, elevator car call registration is executed in step S204, and motion information data as a process result is stored in the interface memory 12b. When the motion information processing command is determined to be process B or process N, hall call registration and reference to the elevator control calculation memory 11d are performed, and the corresponding motion information data is stored in the interface memory 12b. In step S204, when the motion information processing command is executed and the motion information data is stored in the interface memory 12b, the elevator control calculation CPU 11b sets a processing completion flag in the interface memory 12b (step S205). The operation in step S205 indicates that the access to the communication interface memory 12b from the elevator control arithmetic device 11 has been completed. Thus, the operation of the second stage is completed.
[0010]
Third stage:
In the third stage, the maintenance tool 12 reads and edits the operation information data stored in the communication interface memory 12b. In FIG. 3, the maintenance tool CPU 12c of the maintenance tool 12 determines whether or not the contents of the data stored in the communication interface memory 12b can be read even after the processing completion flag of the communication interface memory 12b is reset in step S304. Confirm (step S305). In step S305, when the access from the maintenance tool CPU 12c is possible, the maintenance tool CPU 12c further checks whether or not the processing completion flag of the communication interface memory 12b is set (step S306). If the processing completion flag of the communication interface memory 12b has been set in step S205, the maintenance tool CPU 12c reads the operation information data stored in the communication interface memory 12b, and then executes the maintenance tool memory 12e. (Step S307). In step S305, if the communication interface memory 12b has already been accessed from the elevator control calculation CPU 11b, or if the processing completion flag has been reset in step S306, the maintenance tool CPU 12c returns to step S305 to read data. Repeat the confirmation operation.
[0011]
After storing the operation information data in the maintenance tool memory 12e in step S307, the maintenance tool CPU 12c deletes the operation information processing instruction stored in the communication interface memory 12b (step S308). Next, the maintenance tool CPU 12c edits the operation information data stored in the maintenance tool memory 12e via the maintenance tool program 12d (step S309). By the operation in step S309, the maintenance staff can obtain operation information data in a desired format. Further, the operation information data can be output to the display device 12f as needed. Through the above series of operations, operation information data of the elevator control operation device 11 corresponding to the operation information processing command can be obtained. After editing the operation information data in step S309, the maintenance tool CPU 12c returns to step S302, and continues to execute the selected operation information processing command (Yes in step S310). The above is the operation of the elevator maintenance system shown in FIG.
[0012]
[Problems to be solved by the invention]
In general, an elevator control operation device performs an operation process on an operation information processing command sequentially input at an operation period of 10 m to 50 msec, and outputs operation information data. In addition, in an operation control test of an elevator or the like, since it is necessary to continuously execute an operation information processing command and collect operation information data, an elevator maintenance tool needs a communication interface capable of transmitting and receiving high-speed and large-capacity data. . For this reason, maintenance tools for elevators have conventionally been developed after dedicated designs including hardware and software have been developed. However, high development costs have been a problem. As a solution to the problem, proposals have been made to reduce development costs by using a commercially available personal computer as a maintenance tool.However, the communication interface used for personal computers cannot respond to the transmission and reception speed of operation information data, Omission of operation information data occurs due to the occurrence of periodic interrupt processing in the operating system, and it has been difficult to reliably collect continuous operation information data. Also, in the method of editing the operation information data obtained by the conventional maintenance tool with a personal computer, the maintenance tool is designed exclusively, so it is not compatible with the communication interface of the personal computer, and the data format handled by the maintenance tool There was a problem that it was difficult to use a personal computer because it could not be recognized on a personal computer.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 4 is a configuration diagram of an elevator maintenance system using the elevator maintenance tool according to the embodiment of the present invention. Hereinafter, the configuration of the elevator maintenance system of FIG. 4 will be described. Hereinafter, the same devices and means as those in FIG.
[0019]
The maintenance tool 41 includes a terminal unit 42 and an intermediate processing unit 43. As a role, the terminal unit 42 sets the operation information processing command and processes the operation information data. Is responsible for the control. The elevator interface 11a of the elevator control operation device 11 can be directly connected to the maintenance tool interface 43a of the intermediate processing unit 43. Both interfaces are compatible communication interfaces, and are capable of transmitting bidirectional data in synchronization with the operation cycle of the elevator control operation device 11. Further, the intermediate processing unit 43 includes a communication interface memory 43b that stores the operation information processing command and the operation information data, a maintenance tool CPU 43c that controls the operation of the communication interface memory 43b and edits the received operation information data, It has a maintenance tool program 43d and a maintenance tool memory 43e, and a terminal interface 43f for transmitting and receiving data to and from the terminal unit 42. Here, the specifications and functions of the communication interface memory 43b are the same as those of the communication interface memory 12b of FIG.
[0020]
The terminal interface 43f of the intermediate processing unit 43 is directly connected to the terminal interface 42a of the terminal unit 42, and bidirectional data transmission is possible. Further, the terminal unit 42 has a terminal CPU 42b, a terminal program 42c, and a terminal memory 42d that manage setting and transmission of motion information processing commands and editing of motion information data, and a display device 42e and an input device 42f as auxiliary devices. have.
[0021]
FIG. 5 is a workflow showing the operation of the terminal unit 42. FIG. 6 is a workflow showing the operation of the intermediate processing unit 43. Hereinafter, the operation of the elevator maintenance system of FIG. 4 will be described step by step. Here, the operation of the elevator control arithmetic unit 11 is shown in the workflow of FIG.
[0022]
First stage:
In the first stage, the terminal unit 42 of the maintenance tool 41 transmits a motion information processing command to the intermediate processing unit 43. In the workflow of FIG. 5, the maintenance staff selects the operation information processing instruction to be executed by the elevator control arithmetic device 11 via the terminal program 42c of the terminal unit 42 using the input device 42f (step S501). The motion information processing command selected in step S501 is stored in the transmission buffer provided in the terminal interface 42a by the terminal CPU 42b together with related information (step S502). Here, the related information indicates the format and data length of the data to be transmitted to the elevator control arithmetic device 11 or the data received by the terminal unit 42, and the designated number of executions of the motion information processing command. The designated number of executions is the number of times the maintenance tool 41 causes the elevator control arithmetic unit 11 to continuously perform one operation information processing instruction. By setting the specified number of executions, the intermediate processing unit 43 can receive the operation information data for the specified number of executions independently of the terminal unit 42. The related information is registered in advance in the terminal program 42c, and the registered contents are automatically stored in the transmission buffer of the terminal interface 42a. Next, the terminal CPU 42b transmits the motion information processing command and the related information stored in the transmission buffer of the terminal interface 42a to the intermediate processing unit 43 (Step 503). The motion information processing command and the related information transmitted from the terminal unit 42 are stored in the reception buffer of the terminal interface 43f of the intermediate processing unit 43. At this point, the processing of the motion information processing command and the related information is transferred to the intermediate processing unit 43. Thus, the operation of the first stage is completed.
[0023]
Second stage:
In the second stage, the operation information processing command is read from the communication interface memory 43b of the intermediate processing unit 43 and executed by the elevator control arithmetic unit 11, and the output operation information data is stored in the communication interface memory 43b of the intermediate processing unit 43. To be stored. Furthermore, the operation information data stored in the communication interface memory 43b is transmitted to the terminal unit 42. In the workflow of FIG. 6, the maintenance tool CPU 43c of the intermediate processing unit 43 confirms the presence / absence of reception data in the reception buffer of the terminal interface 43f, so that the operation information processing command and related information are transmitted from the terminal unit 42. It is confirmed whether or not it has been performed (step S601).
[0024]
In step S601, when it is confirmed that the motion information processing command and the related information have been transmitted, the maintenance tool CPU 43c determines whether the transmitted motion information processing command and the related information are correct according to the maintenance tool program 43d. A determination is made (step S602). If it is determined in step S602 that there is an error in the motion information processing command and the related information, the maintenance tool CPU 43c notifies the terminal unit 42 that there is an error, and prompts retransmission of the motion information processing command. Then, the erroneous data in the reception buffer of the terminal interface 43f is deleted. Then, the process returns to step S601, and waits until the motion information processing command and the related information are transmitted again. When it is determined that there is no error, the maintenance tool CPU 43c stores the operation information processing command and the related information from the reception buffer of the terminal interface 43f in the maintenance tool memory 43e. Further, the maintenance tool CPU 43c sets 0 as the number of continuous executions of the motion information processing command, that is, the number of times the same motion information processing command is continuously executed, and stores the number in the memory 43e for the maintenance tool. Next, the maintenance tool CPU 43c uses the maintenance tool program 43d to store the operation information processing command in the communication interface memory 43b according to the data format and data length to be transmitted to the elevator control operation device 11 set as the related information. (Step S604). Next, the maintenance tool CPU 43c resets the processing completion flag in the communication interface memory 43b (step S605). After the operation in step S605, when the elevator control calculation CPU 11b of the elevator control calculation device 11 accesses the communication interface memory 43b, the elevator control calculation device 11 executes the motion information processing instruction stored in the communication interface memory 43b. .
[0025]
The execution of the motion information processing instruction by the elevator control arithmetic unit 11 is the same as the workflow shown in FIG. 2, and thus detailed description is omitted. Specifically, the elevator control arithmetic unit 11 sends the communication interface memory 43b Is read, and the operation information processing command is read, and thereafter, the elevator control arithmetic unit 11 executes the operation information processing command. Eventually, the operation information data is stored in the communication interface memory 43b, and the processing completion flag is set, whereby the operation of the elevator control arithmetic unit 11 ends, and the processing of the operation information data moves to the intermediate processing unit 43.
[0026]
In the workflow of FIG. 6, the maintenance tool CPU 43c of the intermediate processing unit 43 checks whether the operation information data from the elevator control arithmetic unit 11 has been stored in the communication interface memory 43b. Is set (step S606). In step S606, if the processing completion flag is reset, that is, if the operation information data from the elevator control arithmetic unit 11 is not stored in the communication interface memory 43b, the maintenance tool CPU 43c determines that the operation information data is stored. wait. If the processing completion flag is set, the maintenance tool CPU 43c uses the maintenance tool program 43d according to the data format and data length received by the terminal unit 42 set as the related information, and the communication interface memory 43b. Is stored in the transmission buffer of the terminal interface 43f (step S607). Further, the maintenance tool CPU 43c increases the value of the number of continuous executions stored in the maintenance tool memory 43e by 1 in step S601. After the operation in step S607, the maintenance tool CPU 43c deletes the operation information processing command stored in the communication interface memory 43b (step S608), and stores the operation information data stored in the transmission buffer of the terminal interface 43f in the terminal. It is transmitted to the unit 42 (step S609).
[0027]
After the operation of step S609, the maintenance tool CPU 43c compares the number of continuous executions of the motion information processing instruction stored in the memory 43e for the maintenance tool with the designated execution number of the motion information processing instruction set as the related information ( Step S610). If the continuous execution count is less than the designated execution count in step S610, the maintenance tool CPU 43c returns to step S601 and checks again whether the motion information processing command and the related information have been transmitted. If the operation information processing instruction and the related information have not been transmitted in step S601, the maintenance tool CPU 43c confirms that the operation information processing instruction is continuing (step S603), and proceeds to step S604 to store it in the maintenance tool memory 43e. The stored motion information processing instruction is stored again in the communication interface memory 43b. In step S610, when the number of continuous executions reaches the specified number of executions, the maintenance tool CPU 43c deletes the operation information processing instruction, the related information, and the number of continuous executions stored in the maintenance tool memory 43e, and responds to the operation information processing instruction. End the operation.
[0028]
In the operation of the second stage, the maintenance tool CPU 43c causes the elevator control arithmetic unit 11 to sequentially execute the operation information processing instruction, and designates a routine for transmitting the operation information data to the terminal unit 42 after the operation information data is stored in the communication interface memory 43b. The number of times that the operation information data is transmitted to the terminal unit 42 by collectively transmitting the operation information data to the terminal unit 42 after the operation information data is stored in the transmission buffer of the terminal interface 43f for the specified number of times. Can be reduced.
[0029]
Third stage:
In the third stage, the terminal unit 42 of the maintenance tool 41 edits the operation information data transmitted from the intermediate processing unit 43. The operation information data transmitted from the intermediate processing unit 43 in step S609 is temporarily stored in the terminal interface 42a of the terminal unit 42, and the processing of the operation information data shifts to the terminal unit 42 at this time. The terminal interface 42a has a reception buffer capable of storing the operation information data transmitted from the intermediate processing unit 43, and is stored until the terminal CPU 42b of the terminal unit 42 can confirm the operation information data. .
[0030]
In the workflow of FIG. 5, the terminal CPU 42b of the terminal unit 42 confirms whether or not operation information data has been received from the intermediate processing unit 43 by confirming the presence or absence of the operation information data in the reception buffer of the terminal interface 42a. (Step S504). If the reception of the operation information data cannot be confirmed in step S504, the terminal CPU 42b waits for the reception of the operation information data again. If the reception of the operation information data has been confirmed, the terminal CPU 42b determines whether there is any error in the operation information data according to the terminal program 42c (step S505). If it is determined in step S505 that there is an error in the motion information data, the terminal CPU 42b returns to step S502, and transmits the motion information processing command and the related information again to the intermediate processing unit 43. When it is determined that there is no error, the terminal CPU 42b reads the operation information data from the reception buffer of the terminal interface 42a and stores it in the terminal memory 42d (step S506), and uses the terminal program 42c to store the terminal memory 42d. The operation information data stored in the file is edited (step S507). By the operation in step S507, the maintenance person can obtain operation information data in a desired display format. Further, the operation information data can be output to the display device 42e as needed.
[0031]
After editing the motion information data in step S507, the terminal CPU 42b returns to step S502 and continues to execute the selected motion information processing command (Yes in step S508). The above is the operation of the elevator maintenance system shown in FIG.
[0032]
According to the operation of the elevator maintenance system described above, the operation information processing command is set in the terminal unit 42, and the intermediate processing unit 43 transmits the operation information data based on the operation information processing command from the elevator control operation device 11 to the elevator control operation device. It is possible to continuously receive the specified number of executions in synchronization with the eleventh calculation cycle. Further, since the intermediate processing unit 43 transmits the operation information data to the terminal unit 42 using the communication interface of the terminal unit 42, consistency in communication with the terminal unit 42 is ensured, and the terminal unit 42 The transmitted operation information data can be completely received.
[0033]
Further, when the type of the elevator subject to maintenance changes, the elevator control arithmetic device may handle a data format that cannot be supported by the maintenance tool 41 due to a difference in the design specification of the elevator. In order for the maintenance tool 41 to handle operation information data in a new data format, the maintenance tool 41 needs to recognize the data format. To cope with this, in the maintenance tool 41 of the embodiment, it is possible to make the terminal unit 42 recognize the new data format by updating the contents of the maintenance tool program 43d of the intermediate processing unit 43. Specifically, the maintenance tool program corresponding to the conversion of the new data format or the conversion from the new data format is transmitted to the intermediate processing unit 43 via the terminal interface 42a, and stored in the maintenance tool memory 43e. After that, the maintenance tool CPU 43c rewrites the contents of the maintenance tool program 43d. This makes it possible to cope with elevator maintenance that recognizes a new data format without replacing the intermediate processing unit 43.
[0034]
In this embodiment, the maintenance tool 41 is composed of a terminal unit 42 and an intermediate processing unit 43, the operation information processing command set in the terminal unit 42 is executed by the elevator control arithmetic unit 11, and the operation information data is converted into the intermediate processing unit. After being received at 43, the information is converted into a format recognizable by the terminal unit 42, and then the operation information data is transmitted to the terminal unit 42. The operation information data can be continuously collected, and the collected operation information data can be edited by the terminal unit 42. According to this embodiment, for example, it is possible to continuously collect operation information data within a certain specified time and to examine a temporal tendency of the operation information data.
[0035]
If a commercially available personal computer is used as the terminal unit 42, the hardware and software of the intermediate processing unit 43 and the terminal program 42c that realizes the function of the terminal unit 42 installed in the personal computer are to be developed. The development cost can be reduced as compared with the development of the maintenance tool, and the development becomes easier.
[0036]
In addition, since the maintenance tool program 43d that realizes the function of the intermediate processing unit 43 can update the function from the terminal unit 42, without replacing the intermediate processing unit 43 according to the elevator to be maintained, Maintenance work can be performed. Further, the development period of the maintenance tool program 43d for updating the function can be shortened, and the development becomes easy.
[0037]
Further, in the elevator maintenance tool of the present embodiment, since the intermediate processing unit 43 has a configuration independent of the terminal unit 42, it is preferable that the intermediate processing unit 43 receives operating power from the elevator.
[0038]
【The invention's effect】
According to the present invention, an elevator maintenance tool is composed of a terminal unit and an intermediate processing unit, and an operation information processing command is set in the terminal unit and executed by the elevator control arithmetic unit. After receiving the data, the operation information data is converted into a data format that can be recognized by the terminal unit and transmitted to the terminal unit, so that continuous collection and editing of the operation information data synchronized with the operation cycle of the elevator control operation device is possible. Become.
[0039]
Further, by using a commercially available personal computer for the terminal unit, the development cost of the terminal unit hardware can be reduced because there is no need to develop the terminal unit hardware. Furthermore, by updating the software that realizes the function of the intermediate processing unit from the terminal unit when updating the function of the elevator maintenance tool, it is possible to respond only by developing for software update without replacing the intermediate processing unit. The development cost can be reduced and the development period can be shortened, and development can be performed easily.
