Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device with a memory, and more specifically, to a device stored in a memory.
It is about the protection of data.

[0002]

2. Description of the Related Art An analog input signal A applied to an input terminal 1 as shown in FIG.
_In is converted into a digital signal by the input unit 2 including an A / D converter and stored in the memory 3, and then the stored measurement data is analyzed by the analysis unit 4 and the result is recorded / displayed by the recording / display unit 5. Some are configured to output to. An operation unit 6 is provided with a measurement start key 61, an analysis start key 62, and the like. An operation control unit 7 controls the operation of each unit according to the operation of the operation unit 6. Specifically, by operating the measurement start key 61, the measurement operation mode is set and the measurement operation is executed, and the measurement data is loaded into the memory 3. When a predetermined amount of measurement data has been loaded into the memory 3, the analysis start key 62 enters a standby state. When the analysis start key 62 is operated, the operation mode is set to the analysis processing mode, and the necessary analysis processing for the measurement data stored in the memory 3 is executed. The analysis processing includes, for example, reading a measured waveform by displaying a cursor on the display screen, zooming or scrolling the displayed waveform, and obtaining waveform parameters by performing statistical calculation.

By the way, the measurement start key 61 and the analysis start key 62 are provided on the common operation panel surface in the same shape, and the measurement start key is erroneously set in the analysis processing mode. -61 may be operated.

[0004]

However, in the conventional apparatus, when the measurement start key 61 is operated while the analysis processing mode is set, the mode immediately shifts to the measurement operation mode.
The measurement data stored in the memory 3 is new measurement data.
There was a problem that it would be updated to the data. As a result,
The analysis target measurement data stored in the memory 3 is erased and cannot be reproduced in the case of transient measurement data having no periodicity.

The present invention is intended to solve such a conventional problem, and an object thereof is to realize a measuring device with a memory capable of preventing the loss of measurement data due to an erroneous operation of a measurement start key. is there.

[0006]

The present invention provides a measurement operation mode.
The measurement start key that specifies the analysis mode, the analysis start key that specifies the analysis operation mode, the flag that starts when the analysis operation mode is specified, and the analysis operation mode is specified. When the measurement start key is operated in the state where the check alarm is output, the confirmation alarm part that outputs the confirmation alarm with reference to the flag,
An operation control unit that controls the operation of each of these parts and shifts from the analysis operation mode to the measurement operation mode by operating the measurement start key again in the confirmation alarm output state,
It is composed of and.

[0007]

When the analysis processing mode is set, a flag indicating that the analysis operation mode is set is activated. When the measurement start key is operated while the analysis processing mode is set, the confirmation alarm section refers to this flag to confirm that the operator is set to the analysis processing mode. For confirmation, drive the alarm buzzer, turn on the alarm lamp, and display the alarm message on the display screen of the display.
Outputs a confirmation alarm such as a message display. Then, when the measurement start key is operated again in the confirmation alarm output state, the operation control unit shifts from the analysis operation mode to the measurement operation mode. In this way, the operator starts the measurement start key.
By operating the button twice, the analysis operation mode is changed to the measurement operation mode, so that it is possible to prevent the measurement data from being lost due to an erroneous operation of the measurement start key as in the prior art.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.
The same parts as those in FIG. 3 are designated by the same reference numerals. The difference between FIG. 1 and FIG. 3 is that the operation control unit 7 displays a flag 8 indicating that the analysis operation mode is set and a confirmation alarm.
This is because the arm portion 9 is provided.

That is, the analysis operation mode flag 8 is activated through the operation control section 7 by operating the analysis start key 62. Then, the confirmation alarm section 9 is activated via the operation control section 7 by operating the measurement start key 61 in a state where the analysis operation mode is set and the flag 8 is activated. -Warning that the measured data stored in the memory 3 may be erased.

FIG. 2 is a flowchart showing the operation flow of FIG. For example, immediately after the power is turned on or when the analysis operation is completed, the operation key is in the input standby state (step (1)). When the measurement start key 61 is operated in this state (step (2)), it is determined whether or not the measurement data is stored in the memory 3 (step (3)). If the measured data is stored, it is judged whether or not the waveform analysis operation is being executed (step (4)). If the waveform analysis operation is being executed, the confirmation alarm unit 9 issues an error. Mubuza
Confirmation alarm processing such as driving, alarm lamp lighting, and alarm message display on the display screen of the display is executed (step (5)). When any of the panel keys is operated in this state (step (6)), it is determined whether or not the operated key is the measurement start key 61 (step (7)).
When the measurement start key 61 is operated, the waveform analysis operation mode is changed to the measurement operation mode to start the measurement operation (step (8)).

In step (3), the measurement data is stored in the memory 3.
If the data is not stored and the waveform analysis operation is not being executed in step (4), jump to step (8) and start the measurement operation immediately. After the measurement operation is completed (step (9)), operate the analysis start key 62 (step (10)) to enter the waveform analysis operation mode and execute the waveform analysis operation by various key operations. Do (step
(11)). Then, after the waveform analysis operation is completed through a predetermined calculation process (step (12)), the process returns to step (1).
After that, this series of sequences is repeatedly executed.

With this configuration, when the operation start key 61 and the analysis start key 62 having similar shapes are provided on the operation panel, the measurement start key 61 of the operator is provided.
It is possible to prevent the measurement data stored in the memory 3 from being lost due to an erroneous operation, and to give a sense of security to the operator.

[0013]

As described above, according to the present invention,
It is possible to realize a measuring device with a memory that can prevent the loss of measurement data due to an erroneous operation of the measurement start key.
