Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a factory equipment management device that manages each piece of equipment as factory equipment. .

0002

[Conventional technology]

Generally, in manufacturing plants and processing plants, conveyors, pumps, etc. Various equipment such as motors directly affects the production volume, production efficiency, processing volume, and processing efficiency of the factory. equipment as necessary to understand accidents, manual handling conditions, etc. The operating rate is calculated and managed.

0003 Specifically, it is an operation system that detects the operating/stop status of equipment and calculates the operating rate of that equipment. The operating rate calculation device is attached to the equipment at the site, and the operating/stop status of the equipment is calculated at the site. monitoring and compiling statistics and graphs on operating rates.

0004

[Problem that the idea aims to solve]

However, conventional operating rate calculation devices are installed near the equipment that needs to be managed on-site. Therefore, in order to manage the entire factory, it is necessary to collect data from the operating rate calculation device at each site. I had to count it. In addition, a central monitoring device centrally monitors the status of each device. Even in factories that have introduced Therefore, it was not possible to determine the operating rate.

[0005] The purpose of this invention is to centrally monitor the operation/stop status and operating rate of each device. An object of the present invention is to provide a factory equipment management device that does the following.

[0006]

[Means to solve the problem]

The factory equipment management device of this invention detects the operating status of each piece of equipment that is factory equipment. A construction system equipped with a terminal station and a central monitoring station that transmits information between the terminal station and the terminal station via a transmission line. In the field equipment management device, In addition to reading the operating status of each of the above devices from the terminal station, equipment status storage means for storing the running/stopping status of the equipment; operating rate calculating means for calculating the operating rate of each of the devices; the monitoring information display means for visually outputting the operating status or operating rate of each of the devices; It is characterized by being installed at the central monitoring station.

[0007]

[Effect]

In the factory equipment management device of this invention, the terminal station detects the operating status of each equipment and centrally The equipment status storage means installed in the monitoring station records information from the terminal station to each equipment via the transmission line. It reads the operating status and memorizes the running/stopping status of each device over time. Ru. The operation rate calculation means calculates the operation rate of each device, and the monitoring information display means calculates the operation rate of each device. Provides visual output of operating status or availability. Therefore, it is necessary to provide an operating rate calculation device for each device. There is no need to compile data from an operating rate calculation device on site, and everything can be done centrally. It becomes possible to manage the operating status or operating rate of each device from the central monitoring station side.

【Example】

FIG. 1 shows a block diagram of a factory equipment management device that is an embodiment of this invention. In Figure 1 1 is a system control unit, which includes a microprocessor and ROM. , RAM, and peripheral interfaces. Also, in the same figure, 2 is a frame. 3 is a floppy disk device, and 3 is a hard disk device, each of which collects data. data is accumulated. The CRT 4 displays the operating status or operating rate of each device. Ko The console 5 is used to set the operation mode of the central monitoring station. printer 6 prints out the operating status or operating rate of each device. 1 to 6 shown in Figure 1 are central monitoring Configure the station. In Figure 1, 8 to 11 are trunk lines using optical fibers for SCU1. It is a remote controller connected through the transmission system, and can be used for status monitoring, alarm monitoring, and upper/lower limit monitoring. It has functions such as vision. Also, 12 is the terminal controller master, It has a remote controller function and can be connected to a terminal controller. Perform data transmission. 13 to 15 correspond to terminal controller master TCM12. It is a terminal controller connected via a branch line transmission system, and it inputs data between devices. Performs output processing (in this example, inputs the running/stopping status of the equipment). Devices 16-22 are Each of these is a variety of equipment as factory equipment.

[0009] Next, an example of a CRT display and an example of printing by a printer are shown in FIGS. 3 to 5.

0010 Figure 3 shows the operation/performance of each device (device A, device B, and device C in this example) over time. This is an example of a graphical display of a stopped state, with time taken on the horizontal axis and the running state shown on the bar. Display as follows.

[0011] Figure 4 is an example of the numerical display of the operating rate of a specified device, showing the time range for calculating the operating rate and its , the cumulative operating time within that time, and the operating rate are displayed numerically.

0012 Figure 5 is a graph of changes in the operating rate of each device (devices A to D in this example) over a period of one month. This is to display the image.

[0013] Next is a flowchart of the processing procedure of the system control unit shown in Figure 1. As shown in Figure 2. First, remote controllers 8 to 11 and terminal control Reads the current operating status of each device from the roller master 12 via the transmission system. and memorize it (n1→n2). Next, the console key operations are read and the operated If there is a key, the corresponding process is performed (n3→n4). Then the current mode A series of processing is performed depending on the situation. In status display mode, the running/stopping status of each device Create graph display data representing , and write this to the display memory (n5→n6→ n7). As a result, a display as shown in FIG. 3 is displayed. Print instructions can also be set by key operation. If so, the same content is printed out (n8→n9).

[0014] In operation rate numerical display mode, instructions are displayed for the equipment specified by key operation. Calculates the operating rate in the specified time range and writes the result to the display memory ( n10→n11→n12). As a result, the display shown in FIG. 4 is performed. Also key operation If a print instruction has been given by ).

[0015] In the operation rate graph display mode, a graph showing the change in the operation rate of each device for January Create display data and write it to display memory (n15→n16→n17→ n18). As a result, a graph display as shown in FIG. 5 is performed.

[0016]

[Effect of the idea]

According to this invention, there is no need to provide an operating rate calculation device for each device to be managed. In addition, there is no need to aggregate data from an operating rate calculation device on site, and Equipment that could not be equipped with an operating rate calculation device due to equipment limitations will also be collected centrally. It will be possible to manage the operating rate in a medium-term manner.
