Abstract

PURPOSE:To prevent a misoperation by providing an operating direction decision means that decides the direction of the shifting of operation of an object system by means of a current status signal and the past status signal from the object system. CONSTITUTION:The operating direction decision means 30 decides the operating direction in which an object system shifts from the status of the system decided by a system status decision means 4. And a subsequent operation decision means 5 decides the subsequent operation to be requested in said direction decided by the means 30. Thereafter, a display data conversion means 6 converts the subsequent operation decided by the means 5 into display data in form of a guidance message.

FIG. 2 shows an uninterruptible power supply to which this device is applied. In the figure, the original AC input supplied to the AC input terminal 27 is supplied to the rectifier 23 via the switch 21, and its rectified output is is converted into alternating current by the inverter 24, which is supplied to the load via the switch 25a and the output 29, and is also used to charge the battery 28 via the switch 22.

[Problem that the invention seeks to solve]

Conventional operation guidance devices are configured as described above, so the operator determines when to start and stop the system, and selects the guidance device for starting when the system is starting, and the guidance device for stopping when stopping. operation is required,
There was a problem in that erroneous operations could occur due to errors in judgment by the operator.

This invention was made in order to solve the above-mentioned problems. For example, it is possible to automatically determine from the state of the target system whether the target system is starting or stopping. The present invention aims to provide a guidance display device capable of displaying operation guidance messages in the migration direction of the target system.

[Means for solving problems]

The guidance display device according to the present invention includes, in addition to the determining means of a conventional operation guidance device, an operation direction determining means for determining the direction in which the operation of the target system moves based on the current state signal and past state signal of the target system. It has been established.

[Effect]

The guidance display device according to the present invention is provided with the operation direction determining means, so that it is possible to determine the direction in which the operation of the target system will move. A reliable operation guidance message in the direction of movement can be displayed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows a guidance display device according to an embodiment of the present invention. In the figure, 2 is an A/D converter that converts analog signals such as measurement values at observation points of the target system into digital signals, and 3 is the state of the target system. A bit input device for inputting a signal, and 4 a system state determination means for determining the state of the target system from the system state signal input by the bit input device 3 and the digital signal obtained by the A/D converter 2. , 30 is a motion direction determining means for determining the direction of motion of the target system from the state determined by the system state determining means 4, and 5 is the motion direction determining means 4.
6 is a display for converting the next operation determined by the next operation determining means 5 into display data as a guidance message. 7 is a system state determining means 4, a motion direction determining means 30, a next operation determining means 5, and a display data converting means 6.
A CPU 8 which performs a series of controls is a display device which displays the calculation results of the CPU 7.

Next, we will explain the operation of the above embodiment.
Consider the case where this is applied to operational guidance for starting and stopping the uninterruptible power supply shown in the figure. Operation guidance for the uninterruptible power supply is provided by system status determination means 4. Motion direction determining means 30
The primary operation determining means 5 is determined by the display data converting means 6 as shown in the flowchart of FIG.

In FIG. 2, the uninterruptible power supply is activated by switch 20.
Switch 21. Switch 22 to stop. Switch 21. It is assumed that the steps are performed in the order of switch 20. In FIG. 3, first, the A/D converter 2, the bit input device 3, and the switch 20. Switch 21. switch 2
2 status signals are input (step 10). A change in the state signal is determined by comparing the input state signal with the previously sampled state signal (step 11). If it is determined that there is no change in the system status, the process branches to step 17 and the same guidance message as the current one is displayed. If it is determined that there is a change in the state of the system, the state of the system is determined in steps 12A, 12B, and 12G. If it is determined in step 12A that "all switches are not turned on", the process branches to step 13A, and the direction in which the operating direction of the switch 20 moves is determined. In step 13A, switch 20 before change
Exclusive OR is performed between the state signal at and the current state signal at the switch 20, and if the result is "0", it is determined that the switch is moving in the activation direction, and if the result is "1", it is determined that the switch is moving in the stop direction. do.

The direction of operation of this system is determined in step 13B.

The same process is performed in step 13C.

Next, in step 14, the next operation in the direction in which the system operation will move is determined. For example, if it is determined in step 13A that the system is moving in the startup direction, then
If it is determined that the switch 20 is turned on and the system is moving in the stop direction, it is determined that the system is stopped. Furthermore, in step 15, a guidance message corresponding to the determined next operation is created, and a display code corresponding to the guidance message is created. Next, in step 16, the current status signal is stored as the status signal before the change, in preparation for next and subsequent determinations. In step 17, the guidance message created in step 15 is displayed on the display device 8 and output.

In addition, although the case where it applied to the uninterruptible power supply device was demonstrated in the said Example, the effect similar to the said Example is obtained also in other systems. Furthermore, the same effects as in the above embodiments can be achieved not only in systems intended for guidance display but also in other systems related to state determination.

〔Effect of the invention〕

As described above, the guidance display device according to the present invention is configured to include a system operation direction determination means to determine the operation direction of the target system and display guidance during operation. By being able to receive guidance messages that correspond to the next operation without being aware of the driving situation, it has the effect of preventing erroneous operations.
Further, switches for selecting the type of operation guidance are not required, and an inexpensive device can be obtained.
