Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a subsystem consisting of a plurality of devices that is normal when a failure occurs in some of the devices in a system consisting of a plurality of devices. The present invention relates to a normal operating system detection device that automatically detects a system (hereinafter referred to as a normal operating system) in which a predetermined useful effect can be obtained by only fully operating a plurality of devices within the system.

Here, we refer to systems that have a network configuration, such as integrated circuits, water and sewage systems, and chemical platforms.If a failure occurs in some of the multiple devices that make up the system, , instead of completely stopping the operation of the entire system,
Only the normally operating systems in the system are operated.

In the past, humans determined the normally operating system each time based on the system diagram and the notification signal of the faulty device, but this conventional human determination method When the system becomes complicated, not only is there an error in the delayed p1 determination, but there is also a problem that it becomes virtually impossible to make a determination.

The present invention has been made to solve the problems of the above-mentioned prior art.

Hereinafter, the present invention will be explained in detail based on examples.

FIG. 1 is a diagram showing an embodiment of the present invention.

A failure detector 11 provided in each of the plurality of devices constituting the system 1 outputs a failure detection signal to the processing device 2.

The memory 3 contains information about the system l in advance using an input device or the like.
The combination information of the plurality of devices configuring the is stored. The memory 4 stores a subsystem (hereinafter referred to as an operation system), which is a subsystem consisting of a plurality of devices, in which a predetermined useful effect can be obtained by only operating the plurality of devices in the subsystem. The devices included in the system are stored in advance for each operating system.

The processing device 2 performs arithmetic processing, which will be described later, based on the failure detection signal from the failure detector 11, device connection information in the memory 30, and operation system information in the memory 4, calculates a normal operation system, and displays it on the display device 5. do.

The operation of the embodiment shown in FIG. 1 will be explained below using FIGS. 2 to 5.

Let x2..., xn. And each device X,
, X2°, .

In order to apparently replace a multi-input, multi-output system with a single-manpower, one-output system, we assume dummy human-powered device 0 and dummy output device b2, and connect the dummy human-powered device to all input devices of the system. It is assumed that all the output devices of the system and the dummy output device are coupled 1.

Based on these assumptions, the table shown in FIG.

j=1,2. ......n, n+1. n+2) is set in the memory 3 in advance.

However, element C1J has a value of either 1 or 0, and when it is 1, it means that device i and device j are connected, and when it is 0, it is a 0 processing device that means that they are not connected. 2 is
When a failure signal is received from the failure detector 11, calculations 601 to 607 shown in FIG. 3 are performed.

(1) When the processing device 2 receives a fault signal from the faulty device X, it reads the matrix C shown in FIG. .

Set Cr (, n+2) to all 0, element Cl1 of column j
A process 601 (i-carry out 0) in which all lC2j+..., C(n+2), are set to O (2) Next, calculate the M matrix shown in 602. That is, the faulty equipment X + + dummy human-powered equipment 5. For <, (nt) devices excluding the dummy output device b2, determine whether the row of the matrix C corresponding to the device is divided by O. If there is a row in which all row elements are O, then Set the element note level of the column corresponding to O to O.For example, element C111 in the 11th row
CI□・・・・・・.

If all C+(n+2) are O, element CC of column i
,..." (n+2)+ 'Set all O's.

H+ 2+ This is done in order to forcibly remove the element information, which apparently represents the output device, from the i matrix C by setting it to zero since the j row and j column corresponding to the failed device j are set to zero. It is.

Similarly, elements CII, c2 of any i column among the columns of the matrix C excluding the J l (n+1) 7 ("2) column
1゜..., C+2) If all l are O, then the elements of one row are c,..., c, □,...+C1(n+2
) are all set to O.

The reason for doing this is that since the j row and j column corresponding to the failed device j are set to zero, element information that apparently represents the input device is set to zero and removed from the matrix C. The matrix obtained from matrix C in this way is
It is an M matrix.

(3) Next, the calculation operation 603 of the H matrix is performed. 0, that is, H-8M1 1=0 is calculated. Here, m is the number of rows in matrix M excluding rows in which all row elements are O. Also, M
It is assumed that o indicates an (n+2)th order unit matrix. Through this calculation, the coupling between arbitrary devices is calculated.

(4) Next, inner product calculation 604 is calculated. That is, 6
Inner product vector DD = A ′B = (h(
,4])s h+(・+2)・h(・+X)2゛h2(
n4-2)' ”””h(n+1)(n+2bih(・
+2)Cn+2)) is calculated. However, 11. , represents the i-th row and the J-column of the matrix H.

Elements d,', d2. of this inner product vector D.・・・・・・、
Search for all d's that are 1 among do→-2, and restore all device numbers i corresponding to d.

(5) Next, a process 605 is performed to remove the dummy manual device number (n+1) and the dummy output device number (n+2) from the restored plurality of device numbers.

In this way, the device numbers included in all subsystems (hereinafter referred to as normal systems) that do not include a faulty device among the subsystems connecting input devices and output devices are restored.

(6) Next, in step 605, based on the list of device numbers obtained and the matrix C stored in the memory 3, the input device is changed to the output device, without reading the failed device.
A code (hereinafter referred to as a normal system code) is obtained by selecting four normal systems and arranging the equipment numbers from the input device to the output device of the system in order.

(7) Next, in process 607, a normal operating system is calculated. That is, in the memory 4, a code (hereinafter referred to as an operation system code) created by arranging device numbers in order from the input device to the output device of the operation system is stored in advance.
is memorized. The processing device 2 compares the normal code and the operation code by one, and outputs the matched code, that is, the normal operation code that is normal and operable to the display device 5.

The display device 5 includes, for example, the system shown in FIG. 4, the power supply X1.
Main pump x2. Motor X3. Solenoid valve x4゜vacuum pump x
5 + reducer X6. Power supply X7. Corresponding to the system consisting of the cooling tube X8, the display shown in FIG. 5 is made based on the normal operation code.

That is, the display device 5 displays the devices X, , X2 .・
. . . Displays the connection relationship of x8 and 7.

Further, based on the normal operation code, the normal operation systems are indicated by dotted lines, and each system is displayed in a different color in an overlapping manner. Furthermore, failed devices x4°x6 are displayed as double circles.

As explained above, according to the present invention, when a failure occurs in the system,
You can immediately know the normal operating system in case of spillover,
System switching can be performed without error.
