Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management apparatus for collecting data required for managing equipment on a production line and displaying it on a monitor screen.

[0002]

2. Description of the Related Art In a production line or the like in which a plurality of lines are connected, so-called FA (Factory Automation), which centrally manages the operation status of equipment on the plurality of lines, is performed.

FIG. 4 is a PC (programmer controller) which is a plurality of control devices for controlling the equipment 12 connected to the production control device 10 by a network line in order to perform such centralized control of the production equipment. ) 11 is an FA system.

In this FA system, information necessary for managing each facility device 12, for example, whether it is operating normally or in operation, and in the part where temperature control is required, its temperature, hydraulic pressure and pneumatic pressure are indicated. The hydraulic pressure, pneumatic pressure, and the like of the portion that needs to be managed are collected by the PC 11, and as shown in FIG. 5, the registers in the PC 11 are assigned an address for each information and stored.
The data is collected by calling the address in the box and displayed on the monitor (not shown) screen of the production control device 10.

As shown in FIG. 6, the displayed monitor screen graphically displays each facility under management, and the check points necessary for management are provided in the facility equipment of the displayed graphic. By making the checkpoint blink, for example, when a failure or abnormality occurs, or by changing the display color from blue to red, the facility manager can know the operating status of the equipment. .

When constructing an FA system for performing such production control, it is checked whether or not the display of the check points on the monitor screen of the production control apparatus changes depending on the check point information of each equipment. That is, it is important to check whether or not the address of the register in the PC containing the checkpoint information on the monitor screen and the checkpoint information of the equipment is linked as data. If there is a mistake in the connection of this data, for example, the checkpoint a on the graphic showing the heater of FIG. 6 described above does not match the checkpoint a of the heater of the actual equipment, and the actual equipment If the checkpoint a of the heater of the equipment is connected to the checkpoint b of the heater of the graphic, an abnormality occurs at the checkpoint a of the heater of the actual equipment, and data indicating the abnormality is collected as information of this part. However, the checkpoint that changes depending on the data becomes the checkpoint b on the graphic, which causes an abnormality in the management of the equipment.
The production control itself will not work.

Therefore, conventionally, after the FA system was constructed,
In order to check the connection of this data, the operator directly inputs data indicating normality or abnormality to the address in the PC and confirms which checkpoint on the monitor screen changes. It was For example, if data indicating normality or abnormality is directly input to the address in the PC where the information on the checkpoint a of the heater of the actual equipment is stored, and if the checkpoint a on the monitor changes, it will be normal. It can be confirmed that the connection is established, and if the checkpoints other than the checkpoint a change, the connection is determined to be incorrect.

[0008]

However, in the above-mentioned conventional production control apparatus, as described above, it is necessary to manually check the connection of the data between the checkpoint on the screen and the checkpoint on the actual equipment. In the actual production line, the PC that controls the equipment as well as the equipment is placed near the production line because it is performed. On the other hand, the production management device is located in a place different from the production line. It is usually installed in the computer, and in order to perform the work of checking the connection of data, many workers are divided into the PC side and the place where the production control device is located, and use the telephone or the wireless device. It was a very time-consuming and labor-consuming task of keeping in touch with each other.

Therefore, an object of the present invention is to provide a production management apparatus capable of easily checking the connection of data between the production management apparatus and equipment.

[0010]

According to the present invention for solving the above-mentioned problems, a plurality of facility control devices for controlling facility equipment on a line are connected by a network line, and data for each facility collected by the control device. In the production management device that displays the displayed at the specified points on the monitor screen and manages the operating state of each equipment, the specified points displayed on the monitor screen of the production management device are extracted in order in a regular manner. , Check table creating means for creating a correspondence table between designated points and equipments managed by the points, and points extracted by the check table creating means from the production management device in order for each equipment. Check signal transmitting means for transmitting a data request signal,
It is a production management device characterized by comprising.

[0011]

According to the present invention configured as described above, the check table creating means regularly extracts the designated points on the monitor screen of the production management apparatus in order, and establishes the correspondence with the equipment managed by the points. If the data is normally linked by creating a correspondence table and transmitting the data request signal to each equipment control device by the check signal transmitting means in the order of extracting the designated points, the check table creating means creates it. Since the data request signal is accessed to the equipment according to the created correspondence table, the change caused by the check point on the monitor screen, which changes accordingly, changes in the extracted order. By confirming whether or not the changed checkpoints are changed in the order of extraction, it is possible to judge whether or not the data connections are the same.

[0012]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the structure of a production control apparatus to which the present invention is applied. The overall configuration of the FA system is the same as that shown in FIG. 4 described above, and a plurality of PCs, which are facility control devices controlling facility equipment 12 via a network, are connected to the production management device 10. Has been done.

This production management apparatus draws a graphic screen of the displayed equipment from a screen information file 21 on a monitor (not shown) screen of the input / output device 6,
Screen management unit 2 that manages and displays points, PC
The point management unit 3 that reads and writes the point data collected from the register of the point data file 22, the normality of the point from the data of the point data file 22 in which the collected point data of each equipment is stored. Point state determination unit 4, which determines
A monitoring point recognition unit 5 that gives a change instruction of the display of the point according to the judgment of the point state judgment unit 4, a check table management unit 7 that is a check table creation unit according to the present invention, and a created check table are stored. The check table file 20 and the check signal transmitting unit 8 which is a check signal transmitting unit.

One of the connection of data by this device is a hardware connection, such as the connection state of the wiring from the network line to each PC and further inside the PC. The other one is software-like, and is whether there is a register address in the PC and a position for displaying the information collected at the address as each point. In the present invention, the connection of data is checked, including those of hardware and software.

The operation for checking the connection of the data will be described below. In the apparatus of the present embodiment, each point on the graphic screen shown in FIG. 6 is extracted in order, and the check table management unit 7 creates a check table which is a correspondence table of the check points on the equipment of the point. . To this end, a check table is created by extracting points in the order of the X position and the Y position on the screen and associating what the extracted points are. Usually, what is the data collected by each point is determined in advance, and is created based on that. Further, what the point is may be input from the input / output device in the order of extraction. The created check table is stored in the check table file 20.

FIG. 2 shows an example of this check table. The order of the points on the table is from the smaller X of the X and Y coordinates on the screen shown in FIG. 6, and when the X is the same, the smaller Y of them. For this reason,
In the check table shown in, the point (a) in FIG. 6 comes first. Then, in order of (a) and (c), the name of that point and the PCN
o, the address of the register in the PC, the signal name, and the display condition are associated with each other. Further, in this figure, group points are provided so that one related item can be treated as a group.

Next, the check signal transmitter 8 transmits the data request signal to each PC in the order on the check table. In response to this data request signal, the data in the register is returned from each PC in the order of transmission, the data is once stored in the point data file 21, and the point display changes based on the judgment of the point state judging section 4, as described later. . Here, for example, all the data of the point data file 21 is forcibly input and stored in advance by the input / output device 6 so that data indicating an abnormality (or normality) can be stored.
By storing data indicating normality (or abnormality) in all the registers in C, data indicating abnormality is returned by the data request signal. Therefore, in the point state determination unit 4, each point is abnormal. (Or normal)
Is judged to have changed to normal (or abnormal), and the display of each point changes. If the connection of data is correct, the display of points on the screen is
If the values are the same, the values change in order from the smallest Y, and if there is an abnormality in the connection of the data, the order of change in the point display will be out of order. You can

The flow of this operation will be described with reference to the flow chart shown in FIG. First, the point where X is the smallest is calculated (S1). Next, it is judged whether or not the X has a plurality of points (S2), and if there is only one point, in step 7 (S7), the check table is provided with the information corresponding to the point and the point. Register (S
7). If it is detected that there are a plurality of points, the point with the smallest Y is obtained (S3), the point and the information corresponding to that point are registered in the check table (S4), and the value of X is equal. If it is detected that there is a point (S5), a point having a smaller Y value is obtained (S6), and the point and information corresponding to the point are registered (S7).

Then, it is judged whether registration for one screen has been completed (S8), and if not completed, a point having the next smallest X value is obtained (S10), and the process returns to step 2 (S2). When the registration for one screen has been completed, a data request signal is output according to the check table (S9), and the process ends.

Here, regarding the normal operation of the production control apparatus, that is, the operation when all the data connections are correctly made and the operation is performed as the FA system, the point management unit 3 collects data from each PC. Then, the data written in the point data file 22 is
It is also read by the point management unit 3, the state of the equipment is determined from the data by the point state determination unit 4, the determination result is transmitted to the monitoring point recognition unit 5, and the point display on the screen is changed. As described above, the point is changed by instructing the screen management unit 2. The monitoring point recognition unit 5 issues an instruction to change the point display only when the point state determination unit 4 judges that the state of the point has changed. This is because data is collected for the operating state of the equipment that changes from moment to moment, but normally, equipment that is operating normally (maintenance to operate normally) is , The state is continuous, for example, if blue is displayed as the point display and if an abnormality is detected (when it is judged from the data that it is abnormal), change the display to red. Often,
On the other hand, when the abnormality is resolved and returns to normal, the display may be changed, and it is not necessary to give an instruction to change the display when there is no change in judgment in accordance with the data collection. The monitoring point recognition unit 5 needs to change the display by reading the state of the currently displayed point from the screen management function unit 2 to identify the state and comparing the display state with the case where the judgment is changed. In some cases, give a change instruction.

[0022]

As described above, the production management apparatus of the present invention regularly extracts the point position on the monitor screen by the check table creating means and associates the point with the content managed by the point. Since the data request is transmitted by the check signal transmission means in the order of the rules, it is possible to easily check the connection between each point on the monitor screen and the data of the operating state of the equipment.
