Abstract

PROBLEM TO BE SOLVED: To record a preset inspection condition for a plurality of the number of times continuously by forming one inspection unit from opening a data file when a recording start condition is satisfied till closing the data file when a recording end condition is satisfied, and setting an optional count of the inspection units. SOLUTION: According to this recording apparatus, an inspection condition (the number of inspection times) is set first (1a), and whether the condition is satisfied or not is detected (11). At this time, when a recording start condition is satisfied (5), a data file of a data memory recording measurement data with a predetermined sampling cycle from an object to be measured is opened (6). When a recording end condition is satisfied (9), the data file is closed (10). Finally it is detected whether the inspection condition is satisfied or not (11). When the answer is NO, data are continuously received (4). One inspection unit is formed of an interval from the data file is opened until the data file is closed, and a count of the inspection units is optionally set. Accordingly, it becomes possible to record the preset record condition continuously for a plurality of the number of times.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for recording measurement data, and more particularly to a recording apparatus which makes it possible to effectively use a memory, facilitates data analysis, and improves data security.

[0001]

2. Description of the Related Art Measured data from an object to be measured is taken in at a predetermined sampling period, A / D converted, a digitized signal is taken into a CPU, and a predetermined operation is performed. In some cases, the stored data is sequentially read out and displayed on a display device according to a predetermined display format.

FIG. 2 is a block diagram showing an outline of the conventional display device. In FIG. 2, reference numeral 1 denotes an A / D processing unit. The A / D processing unit 1 includes a preamplifier and the like. Reference numeral 2 denotes a CPU that performs a predetermined operation using an operation expression stored in the ROM 3. The RAM 4 is a temporary storage unit that temporarily stores the acquired measurement data and that is used by the CPU 2 during the calculation. Note that the above-defined operation includes, for example, four rules, logarithm, exponential operation, scaling, and the like.

[0003] Reference numeral 2a denotes a recording control processing unit constituting a part of the CPU, and 5 denotes a recording medium, which sequentially records data processed by the CPU 2. Reference numeral 6 denotes a key input processing unit, and reference numeral 7 denotes an external contact input processing unit. For example, a personal computer or another device is connected to a terminal of this processing unit. Reference numeral 8 denotes a display, which displays data processed by the CPU 2.

In such a recording apparatus, (1) for example, when the taken data does not reach a certain standard or exceeds a certain standard, no recording is performed.
(2) In some cases, recording is started after a certain criterion is exceeded, and is stopped when the value falls below a certain criterion.

FIG. 3 shows a recording example of the above (2) in which recording is started after the measured data exceeds a certain reference (20 ° C.) and stopped when the measured data falls below a certain reference (0 ° C.). According to such a recording method, only a predetermined recording range is recorded, so that the recording medium (memory) can be effectively used.

The processing flow of the above (2) can be represented as shown in FIG. That is, a start condition of data recording is set in, and an end condition of data recording is set in (the operator can arbitrarily set such conditions from the key input processing unit shown in FIG. 2). Next, data collection is started.

[0007] Data reception is performed in [1]. Here, if the collected data exceeds (here, 20 ° C.), it is determined that the data recording start condition set in the above is satisfied, and the data file of the recording medium 5 is opened to record the data. If NO, the process returns to the previous stage and no recording is performed.

Next, data reception is continued, and it is determined whether or not the recording end condition is satisfied.
If NO, return to the previous stage to record data. Further, if data reception is performed and the recording end condition is satisfied (here, data of 0 ° C. or less is collected), YES
Then, in (10), the data file on the storage medium 5 is closed to end the data collection.

In such a recording apparatus, a temperature cycle may be applied to a device a plurality of times from a low (high) temperature to a high (low) temperature, such as in a temperature test of a device (not shown). In that case, the device is placed in a thermostat (not shown) and the temperature history is recorded by a recording device. FIG. 5 shows the temperature history of the constant temperature bath when such a temperature test is performed. In the conventional processing flow as shown in FIG. 4, only the range shown in FIG.

[0010] Instead of setting only the data start condition and setting the data end condition, for example, data collection may be performed for a predetermined time (for example, one hour). that way,
That time is convenient because it is not necessary to start up the equipment again.

[Problems to be solved by the invention]

However, in the processing flow as shown in FIG. 4, in order to record the temperature history in the next range B as shown in FIG. 5, the device must be started up again, and the time is determined. In the recording method, extra information (ranges indicated by d and e) is also collected, so that a large memory capacity is required.

In addition, for example, when the period between d and e is long, there is a problem that important information is not collected. For example, when a power failure occurs on the way, all the data collected so far will be lost. Problems also arise. The present invention is to solve such a problem, and an object of the present invention is to improve the security of data by making it possible to effectively use a memory and to continuously record a predetermined inspection condition a plurality of times. The present invention is to realize a recording device aiming at the above.
