A fifteenth invention is characterized in that a program for causing a computer to execute the processing steps of the crane control method according to any one of claims 9 to 13 is recorded on a computer-readable storage medium.

More specifically, for example, in a crane input / output device (information input / output device), a storage medium (program storage medium) for storing and executing dedicated software (application program) for carrying work by the crane. As a configuration, a non-volatile memory having no physically movable portion that stably operates even in a vibration environment is used. As a result, poor access to the storage medium that has caused a failure in a conventional environment under vibration (for example,
Reading errors on the hard disk, etc.) can be reliably avoided.

In addition, software for operating an HTTP client program for obtaining an HTML document from a web server, such as an Internet browser, is installed in a storage medium (non-volatile memory) of the input / output device on the crane. Configuration. As a result, even when a non-volatile memory having a smaller storage capacity than a conventional hard disk or the like is used for an input / output device on a crane, dedicated software is not required by the combination of the non-volatile memory and the browser, and the large capacity is achieved. It is not necessary to use an expensive nonvolatile memory or the like. Therefore, it is possible to input and output information only with a small-capacity nonvolatile memory and an Internet browser program. In addition, the cost required for dedicated software, which was conventionally required for an access mechanism with the ground operation management side, and the cost required for a large-capacity storage medium, together with a CPU having a high processing capability, are surely unnecessary. Therefore, it is possible to provide a crane input / output device using inexpensive general-purpose components.

Further, an open standard network protocol is adopted as a communication interface between a crane input / output device incorporating only an Internet browser and a ground operation management side having a web server and an application server. As a result, the ground operation management side uses the application in the application server to execute the information necessary for executing the application on the input / output device on the crane (the operation information necessary for executing the dedicated software for performing the transfer operation by the crane). ) Can be generated and the web server can provide access to the crane operating information to the on-crane input / output device via the communication path using an open reference network protocol.

Conventionally, it is necessary to incorporate dedicated software for each input / output device on the crane. For example, when a screen application program as dedicated software operating on the input / output device on the crane is changed or modified, For each input / output device on the crane, the application program incorporated in the crane was changed or modified, and during the work, the system for each input / output device on the crane was forced to stop. In the configuration, the interface between the ground operation management side and the input / output devices on each crane can be realized by HTML and HTTP specific to the web technology, so that the ground operation management side can execute the web browser (Internet browser) on each clay. Independent of I / O devices, the above changes or Can change or correct the application program to be corrected, and the interface between the crane input / output device and the ground operation management side after the change or correction is performed depends on the above-mentioned correction or change. Without the initiative of the input / output device on the crane, it is possible to reconnect with the ground operation management side and update the application program. This is because it not only simplifies the complicated interface between the on-crane input / output device and the ground operation management side, but also provides a universal access mechanism without depending on the on-crane input / output device. is there.

The communication method using the open standard network protocol is realized by the following procedure. First, the input / output device on the crane is operated to connect to a web server on the ground operation management side via a communication network interposed between the ground operation management side. At this time, on the ground operation management side, the web server executes an application that functions on an HTTP client program such as an Internet browser stored in the crane input / output device via the communication network.
Notify application server. Then, the web server converts the result of the application executed by the application server into an HTML document format that functions on the HTTP client program in the input / output device on the crane, if necessary, and then converts the result through the communication network. , Transfer to input / output device on crane. In this way, communication between the input / output device on the crane and the ground operation management side is performed.

Further, a general-purpose program operating on the Internet web is used as the application program. For example, the application programs include "JAVA (registered trademark) applet" and "JAVA Beans". "J
An "AVA applet" is a program executed on an Internet browser described in the JAVA language, and a "JAVA Beans" is a program developed and made into parts using the JAVA language.
It can be distributed from a server via a communication network. In this way, with the configuration using the general-purpose program operating on the Internet web, each crane input / output device itself establishes a connection with the ground operation management side, and the ground operation management side connects to each crane input / output device. , Such as setting and monitoring crane operation information. This eliminates the need for providing dedicated software for an interface between the on-crane input / output device and the ground operation management side, and simplifies the configuration between each crane input / output device and the ground operation management side.

The Internet browser 122 is implemented by an information display program as an application program managed by the ground server 110, and provides various screens to the user. Accordingly, the user can easily view information in the HTML format, give various operation instructions, and the like.

More specifically, for example, first, the crane input / output device 120 displays a screen (an information selection menu screen) created in the HTML document format by the Internet browser 122, and receives a message from the user on the screen. The user selection information based on the operation (information on the item of interest selected by the user) is transmitted to the web server 113 of the ground server 110. Thereby, the web server 113 notifies the application program in the application server 112 corresponding to the user selection information from the crane input / output device 120.

Each server 11 of the above ground server 110
More specifically, the information management server 111 first executes, from among the application programs managed by the application server 112, the execution results of the application programs requested and executed by operating the crane input / output device 120. Manage the operation information obtained by The operation information here includes, for example, specification information of articles to be conveyed (in a steel mill, billet numbers as materials, standards, and other related information, etc.), starting and ending points of the article transportation (From-To information). ) And information such as article transport conditions.

The operation information managed by the information management server 111 is called by the application program as required, and is operated by the web server 113 and the network 1.
The data is transferred to the input / output device 120 on the crane via the terminal 30.

The application server 112 manages an application program called by the web server 113, that is, an application program to be operated by the crane input / output device 120. Examples of the application program here include "JAVA applet" such as "Socket communication JAVA applet (application program)" and "GUI (graphical user interface) JAVA applet".

The application program managed by the application server 112 is called by the Internet browser 122 of the on-crane input / output device 120 and transferred to the on-crane input / output device 120 via the web server 113 and the network 130.
This is executed in the on-crane input / output device 120.

That is, the input / output device 120 on the crane
The Internet browser 122 obtains and executes a corresponding application program among the application programs managed by the application server 112 of the ground server 110 via the web server 113 and the network 120. Thereby, the work of transporting the on-crane input / output device 120 by the crane is performed.

The web server 113 sends a notification from the on-crane input / output device 120 to the application server 112 for executing the corresponding application program based on the HTML document and other information, and a message from the application server 112 on the crane input / output device
For example, transfer of an application program functioning on the Internet browser 122 is performed.

As shown in FIG. 3, when a connection request is issued from the on-crane input / output device 120 (S301), the web server 113 determines whether the connection request is permitted or disallowed. Is notified (S302). In addition, as shown in FIG. 3, the web server 113 issues a file request or designation from the crane input / output device 120 (S30).

5) Execute communication disconnection.

FIG. 4 is a flowchart showing the main operation of the ground server 120.

In the ground server 120, first, the web server 113 executes the Internet browser 12 as a client program of the on-crane input / output device 120.
2 via the network 130 (step S401).

Next, the web server 113 sends the application server 112 a message
20 notifies the execution of the application program (step S402).

Next, the web server 113 transmits various operation information required for the on-crane input / output device 120 to execute the application program to the information management server 111.
(Step S403).

The web server 113, together with the application programs managed by the application server 112 and functioning on the on-crane machine input / output device 120, acquires the various operations required to execute the application programs acquired in step S403. The information is transferred to the on-crane input / output device 120 via the network 130 (step S404).

Therefore, the crane input / output device 120
Executes the application program transferred from the ground server 110 based on the various operation information transferred from the ground server 110 together with the application program, thereby performing the transport operation by the crane on the own device side.

As described above, in the present embodiment, the communication between the ground server 110 and the crane input / output device 120 via the network 130 is realized by the general-purpose Internet communication technology such as JAVA or HTML. Therefore, the crane input / output device 120 can acquire and execute a necessary application program from the ground server 110 with only the Internet browser 122. As a result, a necessary application program is previously stored in the crane input / output device 12 as in the related art.
It is not necessary to incorporate the application program into the application program from the ground server 110 according to the situation of the transport operation at that time.
In addition, even when there are many types of transport operations using cranes, it is not necessary to incorporate many application programs corresponding to many types of transport operations into the on-crane input / output device 120 in advance, and the number of types of transport programs depends on the flow of the transport operations. Thus, necessary application programs can be fetched from the ground server 110 and executed. Therefore, the on-crane input / output device 120 does not need to be provided with a CPU having a high processing capacity, a large-capacity memory, a hard disk, or the like, so that the on-crane input / output device 120 can be provided as an inexpensive and highly versatile device. it can.

With the above configuration, the crane input / output device 120 does not need to have a large-capacity memory or a hard disk, so that a relatively small-capacity non-volatile memory is used as a storage medium for storing application programs to be executed. The memory 121 can be used. That is, a nonvolatile memory 121 such as a silicon disk (stationary disk) having no movable portion and having excellent vibration resistance is adopted, and the nonvolatile memory 121 includes the ground server 1.
It is possible to execute the application program for the transport operation acquired from the application program 10. This allows the crane to operate stably even in environments with a lot of vibration,
Suitable transport work can be realized.

In particular, a crane generally used in a factory room or the like is liable to generate vibrations when traveling or traversing on rails due to changes in rail conditions, movement start, or movements when stopping. The installation environment for the upper input / output device (electronic device) is not good. It is very effective for a crane system inside such a factory.

When a modification or change or the like occurs in the application program for the transport operation, the modification or change or the like may be performed on the application program managed by the ground server 110. This is very effective when a plurality of crane input / output devices are connected to the network 130 as in the second embodiment described below.
