Here, an example of a configuration of generating operation screen data by the second control unit 2 and displaying the operation screen by the mobile operation terminal 3 in the present embodiment will be described.

In this example, a Web application is adopted. The Web application has a back end that operates on the server side (second control unit 2 side) and a front end that operates on the user side (worker side: mobile operation terminal 3 side).

The back end refers to a part that executes data processing, data storage, data / signal input / output, etc. of the Web application. The back end is composed of a program constructed in a programming language such as Java, PHP, Python, and Ruby in the second control unit 2 and a database constructed in a database language such as SQL. Further, the second control unit 2 executes an application distribution program for distributing a Web application to the mobile operation terminal 3, a manual distribution program for distributing related books and instruction manuals related to the device 4, and a distribution system thereof. It may include a back end API (Application Programming Interface) of. These programs are stored in the second storage unit 23 of the second control unit 2, and are executed by the second calculation unit 21.

In the present embodiment, the back-end program constructed in the second control unit 2 provides an operation screen corresponding to each of the plurality of devices 4. Therefore, the generation of operation data may indicate that the back-end program is installed, or that the back-end program is read from the second storage unit 23 and executed by the second arithmetic unit 21. good.

The front end refers to a portion that is displayed on the mobile operation terminal 3 and is operated and input on the mobile operation terminal 3 in order for the worker to access the Web application. The foron and the end are composed of programs constructed in a programming language such as HTML, CSS, and Javascript. A Web browser is executed by the terminal calculation unit 31 of the mobile operation terminal 3, and a Web address such as a URL (Uniform Resource Locator) that specifies the Web program of the second control unit 2 is executed on the Web browser. It is executed by being input.

In the present embodiment, the operation screen of the device 4 to be the target device is input by inputting the address of the Web application of the second control unit 2 in the mobile operation terminal 3 and inputting the target device data of the device 4 to be operated. Is displayed on the display unit 34 (touch panel 36). This corresponds to the transmission of the identification data of the device 4, the reception of the operation screen data, and the display of the operation screen.

Next, an operation example of the operation system A1 will be described. In this example, as shown in FIG. 1, the devices 4A, 4B, 4C, 4D, 4E, and 4F are arranged at positions separated from each other as a plurality of devices 4.

FIG. 5 is a flowchart showing an operation example of the operation system A1. In step SS, the operation process in the operation system A1 starts. In step S1, the target device to be operated is selected from the plurality of devices 4, and the identification data is acquired. Specifically, when the device 4A is selected as the target device from the plurality of devices 4, the operator carries the mobile operation terminal 3 and moves to the vicinity of the device 4a. Then, the identification code 41 of the device 4A is photographed by the image pickup unit 37 of the mobile operation terminal 3. The terminal calculation unit 31 acquires the identification code of the device 4A included in the identification code 41 from the shooting data of the image pickup unit 37.

Next, the target device is specified using the identification code (step S2). Specifically, the terminal calculation unit 31 generates a Web address such as a URL based on the identification code of the device 4A. Then, the terminal communication unit 32 accesses the above-mentioned Web address on the Web browser via the communication network N by Wi-Fi or the like. This Web address is based on the identification code of the device 4A and is unique to the device 4A. When the terminal communication unit 32 accesses this Web address on the Web browser, the second calculation unit 21 of the second control unit 2 recognizes the access.

Next, the second control unit 2 generates operation screen data (step S3). However, as described above, if the Web application is already executed on the back end, the operation screen data corresponding to the device 4A may have already been constructed in the second control unit 2. The second control unit 2 distributes the operation screen data corresponding to the device 4A to the second control unit 2 via the communication network N by the above-mentioned distribution program or the like by executing the Web application. This is the transmission and reception of operation screen data. (Step S4).

In this embodiment, the operation screen data is constructed in a programming language such as HTML or CSS. The terminal calculation unit 31 that has received the operation screen data displays the operation screen based on the operation screen data on the display unit 34 as the screen of the Web browser (step S5). FIG. 7 shows an example of an operation screen. Specifically, a Web address such as a URL based on the identification code of the device 4A is automatically input in the address input field Ad of the Web browser, and the actual image, the device ID, etc. that visually display the actual device 4A. An ON / OFF operation button icon, a rotation number display icon, an increase / decrease operation button icon of the rotation number, an end (END) button icon, and the like are displayed. The specific contents of the operation screen of the present invention are not limited in any way. Further, the state of the device 4A such as the rotation speed is transmitted to the mobile operation terminal 3 via the first control unit 1 and the second control unit 2 from the output of the sensor (not shown) provided in the device 4A. May be good. Further, prior to the display of the operation screen shown in FIG. 7, the second control unit 2 may generate mode selection screen data, for example, and the mobile operation terminal 3 may display the mode selection screen based on the mode selection screen data. good. On this mode selection screen, for example, options such as operation of the device 4, drawings related to the device 4, an instruction manual related to the device 4, and the like are displayed. When a drawing related to the device 4 is selected, drawing display screen data is generated based on the drawing data stored in the second storage unit 23 of the second control unit 2, and the mobile operation terminal 3 displays the drawing display screen. Display the drawing display screen based on the data. Alternatively, when the instruction manual related to the device 4 is selected, the instruction manual screen data is generated based on the instruction manual data stored in the second storage unit 23 of the second control unit 2, and the portable operation terminal is used. 3 displays the instruction manual screen based on the instruction manual screen data.

When the operator operates on the illustrated operation screen (step S6: Yes), the operation input is input to the input unit 35 of the touch panel 36. The terminal calculation unit 31 generates operation input data based on the input signal from the input unit 35. Then, the operation input data is transmitted from the terminal communication unit 32 to the second control unit 2 via the communication network N. When the second control unit 2 receives the operation input data, the second control unit 2 transfers the operation input data or the operation input data generated based on the operation input data to the first control unit 1 (step S7). The first control unit 1 controls the operation of the device 4A, which is the target device, based on the received operation input data (step S8).

After the control in step S8 is completed, or when the operation input is not made in step S6 (step S6: No), the mobile operation terminal 3 waits for the operator to finish the operation (step S9). For example, when the end (END) button icon in FIG. 7 is touched (step S9: Yes), the second control unit 2 and the mobile operation terminal 3 end the display of the operation screen of the device 4A (step SE). On the other hand, if the end (END) button icon is not touched (step S9: No), step S6 is executed again.

From the above, the operation of the target device (device 4A) by the operation system A1 is completed.

Next, the operation of the operation system A1 will be described.

According to this embodiment, each operation of the plurality of devices 4 is performed by using the mobile operation terminal 3. Therefore, it is not necessary to install an individual operation panel in the vicinity of each device 4. Therefore, when the plurality of devices 4 are installed in an environment susceptible to corrosion such as a place exposed to seawater, the portable operation terminal 3 which is less susceptible to corrosion or the like can be used for more appropriate operation. In addition, measures to protect the operation panel from corrosion and measures such as repair or replacement of the corroded operation panel cannot be forced. Therefore, it is possible to reduce the burden on the operator and reduce the operating cost of the plurality of devices 4.

A Web application is used in the operation system A1. The generation of operation screen data is realized by executing a back-end program. The mobile operation terminal 3 is limited to executing a front-end program such as a Web browser, and it is not necessary to always store all the operation screen data corresponding to each of the plurality of devices 4. Therefore, the system load of the mobile operation terminal 3 can be reduced. Further, when the number of devices 4 is increased / decreased or the specifications are changed, or when the specifications of each operation screen are changed, the back-end program or database of the second control unit 2 may be changed, and the mobile operation terminal 3 may be changed. There is no need to change the program. Therefore, there is an advantage that system management is easy and when a plurality of workers use a plurality of mobile operation terminals 3, it is not necessary to frequently update each mobile operation terminal 3.

As shown in FIG. 7, on the operation screen displayed on the display unit 34 (touch panel 36) of the mobile operation terminal 3, an image corresponding to the actual device 4A, which is the target device, is displayed. As a result, the operator can more intuitively grasp which of the plurality of devices 4 is the operation target. This is advantageous for simplification of operation and improvement of efficiency. Further, if animation or moving image is used in addition to the still image as the information representing the device 4, it is preferable to perform more accurate operation and various operations.

8 to 10 show other embodiments of the present invention. In these figures, the same or similar elements as those in the above embodiment are designated by the same reference numerals as those in the above embodiment.

<Second Embodiment>
FIG. 8 is a flowchart showing the operation of the operation system according to the second embodiment of the present invention. In this embodiment, step Sa is executed.

Step Sa is a step of determining whether or not the target device (for example, device 4A) selected from the plurality of devices 4 is in a state where the operation input can be accepted. Step Sa may be executed, for example, by the back end of the second control unit 2 or may be executed by the mobile operation terminal 3.

As an example of step Sa, there is a method using the condition monitoring result of the device 4 by the first control unit 1. For example, according to a command from the second control unit 2, the first control unit 1 acquires the output of a sensor (thermometer, pressure gauge, etc.) provided in each of the devices 4. The first calculation unit 11 of the first control unit 1 is in a state in which the target device (for example, device 4A) can be operated by, for example, comparing the operation enablement standard recorded in advance in the first storage unit 13 with the output of the sensor. Judge whether or not. Then, the first control unit 1 transmits the operability data of the device 4A to the second control unit 2.

When the received operationability data is operable (step Sa: Yes), the second control unit 2 executes step S6 and subsequent steps. On the other hand, when the operation enable / disable data is inoperable (step Sa: No), the second control unit 2 ends the operation of the device 4A (step SE).

According to this example, the same effect as that of the operation system A1 described above is obtained. Further, the operation to the device 4A is permitted based on whether or not the device 4A, which is the target device, is in an operable state. Therefore, it is possible to prevent the first control unit 1 from operating the device 4A according to the operation input of the operator even though the device 4A is in a state of being unsuitable for operation. In addition, at a timing other than step Sa, the operation input may be interrupted by interrupt processing or the like based on whether or not the operation is possible. Further, instead of the output of the sensor provided in each of the devices 4, the operation possibility may be determined based on, for example, a changeover switch provided in the vicinity of the first control unit. As the changeover switch, for example, a switch operated by an operator based on higher-level conditions such as a state of a factory or the like in addition to the state of a plurality of devices 4 is exemplified.

As another example of step Sa, the operation input is allowed from the start of displaying the operation screen of the same device 4 (for example, the device 4A) until the preset operable time elapses. That is, in step Sa, the elapsed time from the display of the operation screen in step S5 and the above-mentioned operable time are compared. This comparison may be performed by the second calculation unit 21 of the second control unit 2 or by the terminal communication unit 32 of the mobile operation terminal 3. Then, when the elapsed time does not exceed the operable time (step Sa: Yes), step S6 and subsequent steps are executed. On the other hand, when the elapsed time exceeds the operable time (step Sa: No), the second control unit 2 ends the operation of the device 4A (step SE).

According to this example, the same effect as that of the operation system A1 described above is obtained. Further, it is assumed that the worker is separated from the device 4A after an unnecessarily lapse of time after acquiring the identification data of the target device, for example, the device 4A in step S1. In such a case, if the operation input related to the device 4A is accepted, there is a concern that the operation input without visual confirmation or the like is allowed. According to this example, for example, by setting the operable time to the length of time that the worker is supposed to stay around the target device, the operation input of the worker who has left the target device is prevented. be able to.

FIG. 9 shows another example of the operation system according to the second embodiment. The operation system A2 of this example includes a plurality of radio wave transmitting units 5. Each of the plurality of radio wave transmitting units 5 transmits radio waves used for short-distance positioning such as Beacon. In the illustrated example, the radio wave transmitting units 5A, 5B, 5C, 5D, 5E, and 5F are provided as the plurality of radio wave transmitting units 5. Areas within a predetermined distance set in advance from each of the radio wave transmitting units 5A, 5B, 5C, 5D, 5E, and 5F are set as areas Ra, Rb, Rc, Rd, Re, and Rf, respectively. Devices 4A, 4B, 4C, 4D, 4E, and 4F are arranged in the regions Ra, Rb, Rc, Rd, Re, and Rf, respectively.

FIG. 10 is a system configuration diagram showing the mobile operation terminal 3 of this example. The mobile operation terminal 3 shown in the figure further has an auxiliary communication unit 38. The auxiliary communication unit 38 receives the Beacon radio wave from the radio wave transmitting unit 5, and outputs, for example, the received Beacon radio wave strength. The terminal communication unit 32 and the auxiliary communication unit 38 may be configured as one integrated communication module or may be configured as separate modules.

In step Sa, the terminal calculation unit 31 acquires the Beacon radio field intensity from the radio wave transmitting unit 5A corresponding to the target device (for example, the device 4A) from the auxiliary communication unit 38. Based on this Beacon radio wave intensity, the mobile operation terminal 3 or the second control unit 2 determines whether or not the mobile operation terminal 3 is located in the area Ra. The corresponding data of the plurality of devices 4, the plurality of radio wave transmitting units 5, and the plurality of areas R are stored in advance in the second storage unit 23 of the second control unit 2, the terminal storage unit 33 of the mobile operation terminal 3, and the like. There is. When the mobile operation terminal 3 exists in the area Ra (step Sa: Yes), step S6 and subsequent steps are executed. On the other hand, when the mobile operation terminal 3 does not exist in the area Ra (step Sa: No), the second control unit 2 ends the operation of the device 4A (step SE).

According to this example, the same effect as that of the operation system A1 described above is obtained. Further, by receiving the radio waves from the plurality of radio wave transmitting units 5 by the auxiliary communication unit 38 of the mobile operation terminal 3, the worker (portable operation terminal 3) exists in the area Ra where the target device (for example, the device 4A) exists. The operation input for the device 4A can be allowed only when the operation input is performed. Therefore, when the worker moves away from the target device (for example, the device 4A), the operation input regarding the device 4A can be more reliably blocked.
