Abstract

PURPOSE:To enable an operator having no expert knowledge to operate a monitoring device by displaying guidance in a system operating mode as well as data needed for system operations. CONSTITUTION:When a GUIDANCE key of a switch 1 is pushed, a guidance menu is displayed on a display device 8. Thus a desired function is selected out of the displayed menus. Then the system state signal is supplied through a bit input 3 and a system state deciding means 4 judges a bit that shows the system abnormality. If the abnormality is detected, the abnormal state of the system is displayed on the device 8. When no abnormality is detected, a next operation deciding means 5 decides the operation to be carried out next. Then the next operation is converted into a guidance message by a display data converting means 6. A CPU7 supplies the measurement value designated by an A/D converter 2 and writes data into a designated position of the guidance message to output them to the device 8.

In addition to automatically executing the functions shown in FIG. 7, this device can display measured values, analog waveforms, system operating status, etc. at any time by key operation of the switch (1). An example of the display is shown in FIG. Switch (1)
If the selection of is to display the measured value, c p U (n is the measured value of the contact obtained through the A/D converter (2),
The measured value is converted into display data and displayed on the display device (8) as shown in Fig. 8 (a). On the other hand, CPU (7
) is meanwhile inputting status signals from the uninterruptible power supply system through bit input (3) to monitor the operation of the system.

[Problem that the invention seeks to solve]

Since conventional microcomputer monitoring devices are configured as described above, operating the target system requires specialized knowledge of the system, and there are problems such as careless mistakes and erroneous operations.

This invention was made in order to solve the above-mentioned problems, and provides a guidance display device that can be operated by an operator of a target system without requiring specialized knowledge and that can prevent erroneous operations due to careless mistakes. With the goal.

[Means for solving problems]

In addition to the conventional monitoring device, the monitoring device according to the present invention includes a system state determining means that determines the current state of the system from the state signal of the target system, and a next step that determines the next operation to be performed from the determined state. The apparatus includes an operation determining means and a display data converting means for converting the determined next operation into character data for display on a display device.

[Effect]

The monitoring device according to the present invention can use the above three means to display guidance on the next operation to be performed based on the status of the target system, so the operator of the target system does not need specialized knowledge and can prevent erroneous operations due to careless mistakes. .

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (1) is a switch for specifying a function to be executed by this device, and a 16-key keyboard as shown in FIG. 4 is used, and each key has the function shown in the figure. (2) is an A/D converter that converts analog signals such as measured values of the target system into digital signals; (3) is a bit input that inputs status signals such as the operating status of the target system;
(4) is a system state determination means that determines the state of the target system from the state signal of the target system obtained through the bit input (3), and (5) is the operation to be performed next from the system state determined by the system state determination. (6) is a display data conversion means that converts the next operation determined by the next operation determination means (5) into a guidance message; (7) is the function specified by the switch (1); and A/D converter (2) and bit input (3)
2. A CPU performs calculations based on the data obtained by the display data conversion means (6), and (8) is a display device that displays the results of the calculations of the CPU (7).

Next, the operation will be explained. Let us consider the case where this device is applied to an uninterruptible power supply system. In this embodiment, system status determining means (4) and ninth-order operation determining means (5).

The display data conversion means (6) is implemented by a program, and its operation will be explained in accordance with the flowchart shown in FIG. First, the 1'-GUI of switch (1) shown in FIG.
When you press the DANCEJ key, the guidance menu shown in Figure 5 is displayed on the display R (8). Select a function from the leap from the month (11). If the [month's rstart Up (startup guidance month) is selected, branch to 03 at the @ branch point. Next, enter the bit with αJ ( 3) Inputs the system status signal. Next, at (1Φ), determine which bit of the signal indicates an abnormality in the system, and if it is abnormal, branch to 06. At 0υ, the system status signal is displayed on the display e (8). Displays the abnormal state. If there is no abnormality at the branch of Q41, it branches to (IQ). At aQ, determine the state at the time of system startup from the state signal input by bit input (3), and then Determine the operation to be performed, and shout out a guidance message for the next operation!Determine whether or not it is necessary to display the current value or voltage value of each part of the uninterruptible power supply system in the message data,
