The applicant has a measurement data recording system (hereinafter, simply "collection device") including a measurement device and a measurement data recovery device (hereinafter, also simply referred to as "collection device") that receives and records the measurement data transmitted from the measurement device. The invention of "recording system") is disclosed in the following patent documents.

In this recording system, for example, when measuring and recording the temperature of a measurement target at predetermined time intervals, the measuring device first performs a temperature measurement process according to preset conditions. At this time, in the measuring device, the measuring unit executes temperature measurement at intervals of, for example, 1 second based on preset conditions and outputs the measured value, and the control unit outputs the measured value based on the measured value output from the measuring unit.

As a result, this recording system can execute various analysis processes using the data file in the collection device.

Japanese Unexamined Patent Publication No. 2013-246141 (Pages 5-12, Fig. 1-9)

However, the recording system disclosed in the above patent document has the following problems to be improved.

Specifically, in the recording system disclosed in the above patent document, measurement data (digital data indicating the measured value) is transmitted from the measuring device to the collecting device, and the collecting device collects each measurement data into one and creates a data file. The generated configuration is adopted. For this reason, the recording system disclosed by the applicant requires a dedicated collection device capable of executing a process of collectively generating a data file for each measurement data. For example, the measurement device via a removable memory. It is difficult to refer to and analyze the measurement results collected from the computer with a general-purpose personal computer or the like.

Therefore, the applicant has improved the measuring device so that the process of generating a data file from each measurement data can be executed, and has developed a system capable of outputting the measurement result from the measuring device to an external device in the form of a data file. This makes it possible to output a data file from the measuring device to an external device via a removable memory or a communication path such as wireless communication or wired communication, and execute various analysis processes using the data file. It became.

However, in the above system developed by the applicant, each measured value (measurement data of each measured value) is recorded in the measuring device in parallel with the process of storing the measured values sequentially output from the measuring unit in the storage unit. The configuration is adopted to execute the process of generating the data file. Therefore, it is difficult to output the data file to the external device during the execution of the measurement process, that is, while the measurement value output from the measurement unit is recorded and the data file is generated. There is a problem that the data file showing the measurement result cannot be collected until the measurement process is completed.

In this case, if it is desired to collect the data file before the measurement process is completed, the measurement process is temporarily stopped, the data file in which the measured values up to the stop point are recorded is output to the external device, and then the measurement process is performed. The usage such as restarting is conceivable. However, in such a usage, it is not possible to record the measured value between the time when the measurement process is stopped and the time when the measurement process is restarted, and depending on the purpose of the measurement process, there is a blank time during which the measured value cannot be obtained. In some cases, this cannot be an effective remedy for the above problems.

The present invention has been made in view of the problem to be improved, and the measurement value data file in which the measurement value of the measuring process being executed is recorded is sent to the external device without stopping the measurement process by the measuring device.

Hereinafter, embodiments of the data recording device and the measurement system according to the present invention will be described with reference to the accompanying drawings.

The measuring device 1 shown in FIG. 1 is an example of a "measuring system" configured by integrally including a "measuring device" and a "data recording device", and is an arbitrary measured amount (as an example) for a measurement target. , Current values, voltage values, resistance values, power values and electrical parameters such as phase) are measured and the measurement results are recorded. Specifically, the measuring device 1 includes a measuring unit 11, an operating unit 12, a display unit 13, an external memory mounting unit 14, an internal memory 15, and a processing unit 16.

The measuring unit 11 constitutes a "measuring device" in combination with the processing unit 16, measures electrical parameters of the measurement target according to the control of the processing unit 16, and outputs a measured value Ds (an example of the "measured value"). The operation unit 12 includes a plurality of operation switches for setting the operating conditions of the measuring device 1 and instructing the start / stop of the measurement process, and outputs an operation signal corresponding to the switch operation to the processing unit 16. The display unit 13 displays a display screen (not shown) showing the operating state of the measuring device 1 and the measurement result by the processing unit 16 under the control of the processing unit 16.

The external memory mounting unit 14 is configured so that a memory card 2 which is an example of an “external device” can be mounted, and as will be described later, under the control of the processing unit 16, data files Df1, Df2 ... (“Measured value data”). An example of "file": Hereinafter, when no distinction is made, recording to a memory card 2 such as "data file Df") and reading of various data files recorded in the memory card 2 are executed. The internal memory 15 is an example of a “storage unit”, and stores measured values Ds, data file Df, and the like, as will be described later.

The processing unit 16 is an example of a “processing unit” and controls the measuring device 1 in a comprehensive manner. Specifically, the processing unit 16 controls the measuring unit 11 according to preset measurement conditions, an operation signal from the operation unit 12, and the like to execute the measurement process. Further, the processing unit 16 generates a data file Df for recording the measured value Ds and stores it in the internal memory 15 in parallel with the control of the measuring unit 11 (an example of "first processing").

Further, the processing unit 16 stores the measured values Ds sequentially output from the measuring unit 11 in the internal memory 15 (an example of the “second processing”), and satisfies the “predetermined recording conditions” described later. Occasionally, the measured value Ds stored in the internal memory 15 is recorded in the data file Df (an example of "third processing"). In this case, in the measuring device 1 of this example, as an example, the measured value Ds output from the measuring unit 11 is temporarily stored in the internal memory 15 in the ring buffer format, and the stored measured value Ds is new. A configuration is adopted in which the measurement value Ds is recorded in the data file Df at a cycle in which the recording in the data file Df is completed before the measurement value Ds is erased by overwriting.

Further, as an example, when the processing unit 16 is instructed to record the data file Df in the memory card 2 by the operation of the operation unit 12 ("when the output of the measured value data file to the external device is instructed"). As an example), the data file Df is read from the internal memory 15 and recorded on the memory card 2 (an example of the process of “outputting the measured value data file to the external device”).

In the measurement process (measurement result recording process) by the measuring device 1, as an example, the operation unit 12 is operated to set the operating conditions (measurement conditions and recording conditions). At this time, as a measurement condition, as an example, the voltage value for the measurement target is sampled at a sampling cycle of 100 ms interval, and the maximum value among the values sampled in 1 second is output as the measured value Ds at 1 second interval. Then, set the measurement conditions. In addition, the start condition (start date and time, start trigger condition, etc.) and end condition (end date and time, end trigger condition, etc.) of the measurement process are set as necessary.

As a recording condition, the measured values Ds output from the measuring unit 11 at 1-second intervals are collectively recorded every minute in the data file Df (“60” which is an example of “predetermined number”). Each time the measured values Ds of the above are stored in the internal memory 15, they are recorded in the data file Df). Further, as an example, while the measurement process (recording process) is continued, one data file Df is generated per day, and for the measured value Ds measured after midnight, a new data file Df is generated. Set the conditions for recording in.

Next, the measuring device 1 is connected to the measurement target. In this state, when the set start condition is satisfied, or when the operation of the operation unit 12 instructs the start of the measurement process, the processing unit 16 determines the measured value Ds output from the measurement unit 11. The first data file Df1 for recording is generated and stored in the internal memory 15 (execution of the "first process"). At this point in time when the processing is started, the data file Df1 in which the measured value Ds is not recorded is generated. Further, in order to facilitate the understanding of the measurement process and the recording process by the measuring device 1, it is assumed that the measurement process is started at exactly midnight.

Specifically, when the start condition is satisfied at midnight, the processing unit 16 controls the measurement unit 11 to start the measurement process according to the set measurement condition. At this time, in this example set as described above, the measuring unit 11 samples the voltage value to be measured at a sampling cycle of 100 ms intervals, and measures the maximum value among the values sampled per second. The value Ds is output at 1-second intervals. On the other hand, the processing unit 16 stores the measured value Ds in the internal memory 15 each time the measured value Ds is output from the measuring unit 11 (execution of the "second process").

Further, the processing unit 16 measures when one minute has elapsed from the output of the first measured value Ds from the measuring unit 11, that is, when the storage of the 60 measured values Ds in the internal memory 15 is completed. While continuing the storage processing of the measured values Ds output from the unit 11 at 1-second intervals in the internal memory 15, it is determined that the set "recording conditions" are satisfied, and as shown in the left figure of FIG. , 60 measured values Ds, Ds ... Stored in the internal memory 15 are recorded in the data file Df1 (execution of "third process"). In the figure and the following description, 60 measured values Ds, Ds ... Recorded in the data file Df at 1-minute intervals are referred to as measured values Ds1, Ds2 ...

Further, the processing unit 16 newly records the measured value Ds1 in the data file Df1 when 2 minutes have passed since the first measured value Ds was output from the measuring unit 11. When the storage of the 60 measured values Ds in the internal memory 15 is completed, the "recording condition" is continued while continuing the storage processing of the measured values Ds output from the measuring unit 11 to the internal memory 15 at 1-second intervals. Is satisfied again, and as shown in the right figure of FIG. 2, 60 new measured values Ds, Ds ... (Measured value Ds2) stored in the internal memory 15 are stored in the data file Df1. Record (execute "third process").

By continuously and repeatedly executing such processing, when 24 hours have passed since the first measured value Ds was output from the measuring unit 11, the data in the internal memory 15 is as shown in FIG. In the file Df1, 86,400 measured values Ds, Ds ... Of the measured values Ds1 to Ds1440 are recorded.

Further, in this example in which one data file Df is generated per day, the processing unit 16 stores the measured values Ds output from the measuring unit 11 at 1-second intervals in the internal memory 15. When the recording of Ds1440 for the data file Df1 is completed, the recording of the measured value Ds in the data file Df1 is completed, and a new data file Df2 for recording the measured value Ds on the second day is generated. And store it in the internal memory 15.

At this time, the processing unit 16 makes it possible to identify that the measured values Ds, Ds ... Recorded in the data file Df2 are the measurement results following the measured values Ds1440 recorded in the data file Df1. As an example, the file name of the data file Df2 is determined according to a predetermined file name determination procedure (an example of the process of "adding association information"). As a result, a person who later sees the data files Df1 and Df2 can surely and easily specify the measurement order of the measured values Ds, Ds ... Recorded in both data files Df.

Further, the processing unit 16 has an internal memory of 60 new measured values Ds at the time when 24 hours and 1 minute have passed since the above-mentioned first measured value Ds was output from the measuring unit 11, that is, on the second day. When the storage in the 15 is completed, it is determined that the set "recording condition" is satisfied while continuing the storage processing of the measured value Ds output from the measuring unit 11 into the internal memory 15, and the internal memory. The 60 new measured values Ds, Ds ... (Measured value Ds1) stored in 15 are recorded in the data file Df2 (execution of the "third process").

After that, the measured values Ds are stored in the internal memory 15 and stored until the measurement process (recording process) is instructed to be stopped by the operation of the operation unit 12 or until the set end condition is satisfied. Recording of 60 measured values Ds in the data file Df is repeatedly executed.

Further, in the measuring device 1 of this example, the data file Df in the internal memory 15 is stored in the memory card before the stop instruction or the state where the end condition is satisfied (an example of "before the end condition is satisfied"). When the instruction to be recorded in 2 (an example of "instruction to output the measured value data file to the external device") is given, the processing unit 16 executes the following processing. Specifically, as an example, at 0:30:30 on the third day from the start of processing, an instruction is given to record the data file Df in the internal memory 15 on the memory card 2 by the operation of the operation unit 12. And.

At this time, as shown in FIG. 4, the data file Df3 for recording the measured values Ds, Ds ... On the third day completed the recording of the measured values Ds3 at 0:03 and 0:04. A state in which the measured value Ds4 is to be recorded in a minute, that is, a state in which data is being recorded and reading or deletion is restricted. Therefore, at 0:30:30, the data file Df3 cannot be read and cannot be copied, so that the data file Df3 can be moved or copied to the memory card 2. Can not.

On the other hand, in the measuring device 1 of this example, when the instruction to record the data files Df1 to Df3 in the internal memory 15 is given to the memory card 2 as described above (recording of the measured value Ds by the "third process"). When the data file Df including the data file Df3 is instructed to be recorded in the memory card 2), the processing unit 16 stores the measured values Ds output from the measuring unit 11 in the internal memory 15. Is continuously executed, and when 60 new measured values Ds, Ds ... Are stored in the internal memory 15 at 0:04, it is determined that the "recording condition" is satisfied, and the new measured value is determined. Record Ds, Ds ... (measured value Ds4) in the data file Df3 (execution of "third process").

Next, the processing unit 16 ends the recording of the measured value Ds in the above-mentioned data file Df3 that has completed the recording of the measured value Ds4, and at the same time, stores the measured value Ds output from the measuring unit 11 in the internal memory 15. The three files Df1 to Df3 instructed to be recorded on the memory card 2 are read from the internal memory 15 and recorded on the memory card 2 from the external memory mounting unit 14 (“measured value data file is externally recorded”. An example of the process of "outputting to the device").

As a result, by removing the memory card 2 from the external memory mounting unit 14 and mounting it on an arbitrary information processing terminal, the data file Df1 in which the measured values Ds, Ds ... Data file up to the data file Df3 in which the measured values Ds, Ds ... The measured values Ds, Ds ... Recorded in the three files can be viewed and analyzed by the information processing terminal.

In this case, in the measuring device 1 of this example, the file names of the data files Df1 to the data file Df3 are determined according to a predetermined file name determination procedure, and the measurement order of the measured values Ds in each data file Df1 to the data file Df3 is determined. Can be specified from the file name, so that the measured values Ds from the start of measurement to 0:04 on the third day can be reliably and easily viewed and analyzed in chronological order.

On the other hand, the processing unit 16 finishes recording the measured value Ds in the data file Df3 and records the data files Df1 to Df3 in the memory card 2 as described above, and the internal memory of the measured value Ds output from the measuring unit 11 While continuing the storage process to 15, as shown in FIG. 5, a new data file Df4 for recording the measured values Ds, Ds ... After the measured value Ds5 on the third day is generated and stored in the internal memory 15. (Execution of "first process"). At this time, the processing unit 16 specifies that the measured values Ds, Ds ... Recorded in the data file Df4 are the measured values Ds, Ds ... Following the measured values Ds4 recorded in the data file Df3. To make it possible, the file name of the data file Df4 is determined according to a predetermined file name determination procedure (an example of the process of "adding association information").

After that, the processing unit 16 stores the measured values Ds output from the measuring unit 11 in the internal memory 15 until the stop instruction is given or the set end condition is satisfied. The recording process of 60 new measured values Ds, Ds ... In the data file Df is repeatedly executed. As a result, when 72 hours have passed since the first measured value Ds was output from the measuring unit 11, as shown in FIG. 6, the data file Df4 of the internal memory 15 has 86 of the measured values Ds5 to Ds1440. , 160 measured values Ds, Ds ... Are recorded, and a data file Df5 for recording the measured values Ds after the 4th day is generated and stored in the internal memory 15.

As described above, in the measuring device 1, the data file Df before the processing unit 16 satisfies the predetermined "end condition" for ending the recording of the measured value Ds by the "third process" in the data file Df. When the recording to the memory card 2 (output to the external device) is instructed, the "second process" for storing the measured values Ds sequentially output from the measuring unit 11 in the internal memory 15 is continuously executed. At the same time, the recording of the measured value Ds by the "third process" in the data file Df instructed to be output is completed, the data file Df is recorded in the memory card 2, and the recording in the output data file Df is completed. The "first process" of generating a new data file Df for recording the unmeasured value Ds and storing it in the internal memory 15 is executed.

Therefore, according to the measuring device 1, the data file Df, which was recording the measured value Ds at the time when the recording to the memory card 2 is instructed, is stored in the memory card 2 without stopping the measurement process by the measuring unit 11. Therefore, it is possible to acquire the data file Df and perform arbitrary processing (viewing and analysis of the measured value Ds) without causing the measured value Ds to be lost due to the stop of the measurement process.

Further, in the measuring device 1, each time the processing unit 16 completes the storage of the measured values Ds of a predetermined number (60 in this example) in the internal memory 15 by the "second processing", the "first" is performed. While continuously executing "2 processing", it is determined that the "recording condition" is satisfied, the "third processing" is executed, and the data file Df is transferred to the memory card 2 before the "end condition" is satisfied. When the recording is instructed, the "recording condition" is satisfied when the "second processing" is continuously executed and the storage of the predetermined number of measured values Ds in the internal memory 15 is completed. After discriminating and executing the "third process", the recording of the measured value Ds by the "third process" to the data file Df instructed to output is completed, the data file Df is recorded in the memory card 2, and the data file Df is recorded in the memory card 2. The "first process" for generating a new data file Df is executed.

Therefore, according to this measuring device 1, the data file Df including the latest measured value Ds measured at the time of being instructed to be recorded on the memory card 2 can be recorded on the memory card 2, so that, for example, measurement is performed. When an abnormality of the target is detected and the data file Df is to be recorded in the memory card 2, the data file Df in which the measured value Ds that can identify the abnormal state is recorded can be acquired.

Further, according to the measuring device 1, the data file Df that the processing unit 16 has finished recording the measured value Ds by the "third processing" and the new data file Df generated by the subsequent "first processing". "Association information" given by assigning association information that associates both data files Df with each other to at least one of the data files (in this example, the association between the two data files Df is a identifiable file name). Based on (in this example, a file name whose relevance can be specified), each measured value Ds, DS ... Recorded across a plurality of data files Df can be reliably and easily arranged in chronological order. Therefore, the measured values Ds, Ds ... Recorded in each data file Df recorded in the memory card 2 can be easily browsed and analyzed.

The configurations of the "data recording device" and the "measurement system" are not limited to the above-mentioned example of the configuration of the measuring device 1. When the recording of the data file Df to the memory card 2 (output to an external device) is instructed during the recording of the measured value Ds to the data file Df, the recorded value Ds to the data file Df is recorded at that time. When the storage of 60 new measured values Ds in the internal memory 15 is completed and the measured values Ds are recorded in the data file Df without ending, the measured values Ds are recorded in the data file Df. Although an example of the process of ending the process and recording the data on the memory card 2 has been described, the form of the process by the “data recording device” is not limited to this example.

For example, when the recording of the data file Df to the memory card 2 (output to an external device) is instructed during the recording of the measured value Ds to the data file Df, the recorded value Ds is recorded to the data file Df. Is immediately terminated and recorded in the memory card 2, and the measured value Ds at the time when the recording of the data file Df in the memory card 2 is instructed is a new data file different from the data file Df recorded in the memory card 2. A processing mode for recording in Df can be adopted.

Further, when the data file Df is instructed to be recorded on the memory card 2 (output to an external device) during the recording of the measured value Ds on the data file Df, and the data file Df is recorded on the memory card 2. , The new data file Df does not record the measured value Ds recorded in the data file Df that has completed the recording to the memory card 2, but the new measurement after the instruction to record to the memory card 2 is given. Although an example of the process of recording only the value Ds has been described, the form of the process by the “data recording device” is not limited to this example.

Specifically, in the "first process" in which the processing unit 16 records the measured value Ds in the memory card 2 and generates a new data file Df, immediately before the measured value Ds recorded in the new data file Df. It is possible to adopt a configuration in which all the measured values Ds recorded in the data file Df in which the output measured values Ds are recorded are recorded in the new data file Df.

More specifically, as shown in FIG. 7, when the processing unit 16 records the data file Df3 that has completed the recording of the measured value Ds4 on the memory card 2, as an example, it is referred to as a “new data file”. Generate a data file Df3a in which the measured values Ds1 to Ds4 that have been recorded in the data file Df3 are recorded (duplicate the data file Df3 to generate the data file Df3a) and store it in the internal memory 15. The process is executed as the "first process".

At this time, it is preferable to add "association information" (for example, a file name that can identify the relationship between the two files) that can specify the relationship between the data file Df3 and the data file Df3a. Further, the processing unit 16 refers to the data file Df3a for the measured values Ds (measured values Ds5, Ds6 ...) After the recording of the data file Df3 on the memory card 2 and the generation of the new data file Df3a are completed. Record after the measured value Ds4.

Therefore, according to the measuring device 1 having such a configuration, the measured values Ds1 to be recorded in the data file Df3 in which the recording of the measured value Ds is terminated in the middle only by acquiring the generated new data file Df3a. All measured values Ds, Ds including Ds4 can be specified. As a result, when the acquisition of the new data file Df3a is completed, the data file Df3 for which the recording of the measured value Ds is terminated in the middle becomes unnecessary, so that the data file Df can be easily managed.

Further, each time the storage of the predetermined number (60 in the above example) of the measured values Ds in the internal memory 15 is completed, it is assumed that the "recording condition" is satisfied, and the measured values Ds are stored in the data file Df. Although the configuration for executing the "third process" to be recorded in is described as an example, the "recording condition" for executing the "third process" is not limited to the above example, and is measured from, for example, the measuring unit 11. Each time the value Ds is output, it is determined that the "recording condition" is satisfied and recorded in the data file Df, or each time the measured value Ds of the preset signal level is output from the measuring unit 11, the "recording condition" is recorded. It is also possible to adopt a configuration in which it is determined that "" is satisfied and recorded in the data file Df.

Further, an example of outputting (recording) a data file Df using the memory card 2 as an "external device" has been described, but the "external device" is not limited to this, and various information processing such as personal computers, tablet terminals, and smartphones. It is also possible to adopt a configuration in which a terminal or a “measuring device” different from the measuring device 1 that generated the data file Df is used as an “external device” and the data file Df is output to them. When such a configuration is adopted, the instruction to output the data file Df to those devices corresponds to "when the output of the measured value data file to the external device is instructed".

In this case, the connection form between the "external device" and the "data recording device" (the output form of the "measured value data file") is "as in the example of the configuration of the measuring device 1 and the memory card 2 in the above example. It is not limited to the configuration in which the "external device" is attached to the "data recording device" and the "measured value data file" is output. For example, an "external device" can be connected to a "data recording device" via various signal cables, or an "external device" can be connected to a "data recording device" via a wireless LAN or a wireless communication path conforming to Bluetooth (registered trademark). Or connect an "external device" to a "data recording device" via a network communication network such as a mobile phone communication network or an internet communication network, and "measure" from the "data recording device" to the "external device". A configuration that outputs a "value data file" can be adopted.

Further, as "assignment of association information", a configuration in which the file name of each data file Df is determined according to a predetermined file name determination procedure has been described as an example, but instead of such a configuration (or this configuration). Information that can identify the relationship between both data files Df and Df can be recorded in at least one of both data files Df and Df, and the relationship between both data files Df and Df can be specified. It is also possible to adopt a configuration in which the association data file in which the information is recorded is associated with at least one of both data files Df and Df and generated separately from both data files Df and Df.

In addition, the configuration of the measuring device 1 capable of measuring various electrical parameters has been described as an example, but the parameters to be measured by the "measuring device" and recorded by the "data recording device" are shown in the above example. Not limited, measure any measured amount such as temperature, humidity, strain, brightness (luminance), illuminance, rainfall, flow rate, atomic weight / molecular weight / chemical formula / chemical equivalent, mass / substance amount and gas volume. It can be configured to be recordable.
