[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device having a function of displaying and recording measurement results, and more particularly to improving facsimile transmission of measurement results.

[0002]

2. Description of the Related Art When measuring physical quantities of various measuring objects such as voltage, current, temperature, pressure, strain, vibration, and sound, these physical quantities are sampled at a desired sample rate and collected and stored in a memory as measurement data. , Display the collected and stored measurement data on the display as needed,
Recording on recording paper, analysis processing, etc. are performed.

By the way, depending on a specific measurement mode,
Sometimes, you may want to obtain the measurement results of a measurement device located at a remote measurement site at any time you want to see.
In the past, as one of the solutions to such a request, an operator at the measurement site was requested to output the measurement result on a recording paper, and the recording result was transmitted by facsimile. .

[0004]

However, in such a conventional method, since the recording result once output on the recording paper is transmitted by facsimile, the work man-hours for that are generated, and the measuring device side is required to work. Is unavailable when the person is absent. Further, since the recording result output on the recording paper is read as image image data by the facsimile on the transmitting side and then transmitted by facsimile, the sharpness of the received recorded image on the receiving side is not always sufficient.

The present invention is intended to solve such a conventional problem, and an object thereof is to obtain a clear measurement record image by facsimile transmission from a remote place at any time when it is necessary without the intervention of others. It is to realize a measuring device.

[0006]

A measuring device of the present invention is a telephone line processing unit to which a facsimile is connected via a telephone line, a measuring unit for sampling measurement data, and a measuring data sampled by the measuring unit. A data processing unit having an arithmetic processing function, a control function of a telephone line processing unit, and a type identifying function of a facsimile connected via a telephone line, a data storage device for storing data processed by the data processing unit, and a data processing An image generation processing unit that generates image data suitable for the transmission type of the facsimile type identified by the unit from the data stored in the data storage device and outputs the image data to the telephone line processing unit. The feature is that the image data can be directly transmitted from the measuring device body to the facsimile connected via the. To.

[0007]

The main body of the measuring device performs normal measurement processing, and transmits image data directly to an external facsimile machine as needed. This eliminates the need for the work man-hours required for facsimile transmission of the recording result once output on the recording paper, so that the image data can be obtained even when the operator is not present at the measuring device side, and the facsimile data to be transmitted can be obtained. The image generation processing unit generates image data suitable for the transmission formats of the above types and outputs the image data to the telephone line processing unit. Therefore, it is possible to improve the deterioration of the sharpness of the received recorded image on the receiving side due to the reading of the image data.

FIG. 2 is a block diagram for explaining various data flows when image data is transmitted from the measuring device 9 to the facsimile 3 via the telephone line 2 in the configuration of FIG. The common parts are given the same reference numerals. As a form of transmitting the image data to the facsimile 3, for example, there are regular transmission from the measuring device 9 at regular time intervals (A) regular transmission, and irregular transmission in response to a request (B) request transmission. The operation in each case will be described.

(A) Scheduled transmission When the preset transmission time is reached, the image generation processing unit 7 takes in the data stored in the data storage device (not shown) via the data processing unit 5, and sends it to a facsimile machine (not shown). Image data to be transmitted that conforms to the transmission formats of the above types is generated and stored in the image data memory area provided inside the image generation processing unit 7.

When the image data generation is completed, the data processing unit 5 connects the measuring device and the destination facsimile via the transmission processing unit 11, the telephone line transmitting / receiving unit 12, and the telephone line 2 of the telephone line processing unit 1. Then, the generated image data is transmitted from the image generation processing unit 7 to the destination facsimile via the telephone line transmitting / receiving unit 12 and the telephone line 2.

After the transmission is completed, the measuring device uses the telephone line 2
Open up. (B) Request transmission The telephone line transmission / reception unit 12 of the measuring device and a request source facsimile (not shown) are connected via the telephone line 2. A facsimile data request command is sent from the requesting facsimile device to the data processing unit 5 via the telephone line 2, telephone line transmission / reception unit 12 and command conversion unit 13.

When the data processing unit 5 confirms the request command and the type of the requesting facsimile, the response processing unit 1
4. A response command is sent to the requesting facsimile via the telephone line transmitting / receiving unit 12 and the telephone line 2. After that, since it may take time to generate image data in the measuring device, the measuring device opens the telephone line 2 once.

When the data processing unit 5 confirms the request command, the image generation processing unit 7 fetches the data stored in the data storage device (not shown) via the data processing unit 5, and the type of the requesting facsimile (not shown). The image data to be transmitted conforming to the transmission format is generated and stored in the image data memory area provided inside the image generation processing unit 7.

When the image data generation is completed, the data processing unit 5 connects the measuring device and the destination facsimile via the transmission processing unit 11, the telephone line transmitting / receiving unit 12, and the telephone line 2 of the telephone line processing unit 1. Then, the generated image data is transmitted from the image generation processing unit 7 to the destination facsimile via the telephone line transmitting / receiving unit 12 and the telephone line 2.

After the transmission is completed, the measuring device uses the telephone line 2
Open up. The data conversion unit 15 is used when transmitting a character code instead of image data. FIG. 3 is a flowchart showing an example of the flow of the main part of the operation of the apparatus of the present invention.
The steps surrounded by broken lines are executed when it takes a relatively long time to generate the image data, and are skipped when the image data is generated in a short time.

After the line is connected in step (1), the ID check is performed in step (2). If the ID check is correct, the password check is performed in step (3). Here, the ID check and the password check are necessary for data security. If an error occurs in these ID check and password check, skip to line disconnection in step (12). If the password check is correct, if the time required to generate the image data is long, the confirmation response in step (4) is sent, and if the time required to generate the image data is short, the image data generation process in step (6) is performed. To do. After the confirmation response, the line is disconnected in step (5), and then the image data generation process in step (6) is performed. If the line is connected when the image data generation process is completed, the image data transmission process of step (11) is executed. If the line is disconnected, the image data of step (11) is passed after dialing in step (7), line connection in step (8), ID check in step (9) and password check in step (10). Execute the sending process. Then, even if an error occurs in these line connection, ID check and password check, step (1
Skip to line disconnection in 2). When the image data transmission process is completed, the line is disconnected in step (12).
After disconnecting the line, the process history storage of step (13) is executed. By storing the history of line processing in the measuring device by this processing history storage, trouble analysis can be efficiently performed.

With this configuration, the image data of the measurement data generated by the measuring device can be directly transmitted to the facsimile via the telephone line, and the recording paper on which the measurement data is recorded can be read by the facsimile. Compared to the case of transmitting afterwards, a clearer image can be transmitted. And since it is not a dedicated line, the measurement data of one measuring device can be shared by a plurality of facsimiles.

Further, by using the radio telephone, the measuring device can be arranged even in a place where the line construction is difficult. Also,
Since the image based on the image data from the measuring device can be received by the general-purpose facsimile, the data manager can obtain the measurement result without the need for manpower at the place where the measuring device is installed, without having to go to the place where the measuring device is installed.

By transmitting character data such as a daily report as image data of a facsimile, the information of the measuring device can be obtained as a numerical value. Furthermore, by using the communication function of the telephone line, it is possible to perform remote operations such as setting measurement conditions for the measuring device and controlling the start and end of measurement. In addition, although the example in which the measuring device is a recorder has been described in the above embodiment, the measuring device can be applied to a device having no recorder function.
