DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement recording system for recording continuous measurement data from a large number of measurement points on a recording medium as waveform data or numerical data.

[0002]

2. Description of the Related Art A so-called recorder that records continuous measurement data from a number of measurement points on a recording medium as waveform data or numerical data is conventionally known. This recorder is a device that receives a signal transmitted from one or a plurality of measurement points as measurement data, and records waveform information or the like based on the received measurement data on long paper.
In the measurement recording system using such a recorder, when recording the measurement data for each measurement point, the recording surface of the recording paper is divided into predetermined areas, and one measurement point is recorded for each divided area. A so-called zone recording method or a method of connecting a dedicated recorder for each measurement point has been adopted.

[0003]

In the former method, measurement data at a plurality of points are drawn on one sheet of recording paper. Therefore, when the measurement data is sorted and stored at each measurement point, the recording data is not recorded. There is a problem that post-processing such as cutting the paper is required. In the latter method, since a dedicated recorder is connected to each measurement point, there is a problem that the apparatus becomes expensive when handling a large number of measurement points. In addition, since a long recording medium is used in any of the methods, a great deal of labor is required for organizing the recorded medium, and the amount of use is large. The present invention has been made to address these problems, and an object of the present invention is to provide an inexpensive measurement recording system for separately recording measurement data from a large number of measurement points, and to facilitate the organization of recorded media. Another object of the present invention is to provide a measurement recording system capable of reducing the amount of medium used.

[0004]

Therefore, in the apparatus according to the first aspect of the present invention, after receiving continuous measurement data from a measurement point, the measurement data is displayed and stored in a storage device, and the stored measurement data is stored. It has means for transmitting data at a predetermined timing, and a terminal device arranged corresponding to a plurality of measurement points, and recording the measurement data from this terminal device on a single-leaf medium, and The present invention proposes a measurement recording system including a recording device provided with a separation unit that separates each measurement point. According to a second aspect of the present invention, there is provided a measurement recording system according to the first aspect, wherein the measurement data is transmitted at predetermined intervals for each terminal device when the measurement data is transmitted from the terminal device.
According to a third aspect of the present invention, there is provided a measurement recording system according to the first aspect, further comprising a recording device having a double-sided recording means for recording on both surfaces of a single-leaf medium.

[0005]

According to the first aspect of the present invention, the recording device is shared by a plurality of terminal devices, so that the device can be simplified, and this recording device separates the recording medium on which recording has been completed for each measurement point. Therefore, the organization of the recorded medium can be saved. According to the second aspect of the present invention, the transmission timing of the measurement data of each terminal device is delayed for each terminal device for a predetermined time, so that the recording device can be used effectively, and highly efficient processing can be realized. In the apparatus according to the third aspect, since the recording apparatus having the double-sided recording means for recording on both sides of the single-leaf medium is used, the amount of the medium required for recording can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. First, the configuration of the measurement recording system of the present invention will be described. FIG. 1 is a block diagram showing a configuration of a measurement recording system according to the present invention, FIG. 2 is a configuration diagram illustrating a terminal device 2, and FIG. 3 is a configuration diagram illustrating a recording device. Please refer to FIG. The illustrated system includes a host computer 1 and a plurality of terminal devices 2.
(2a to 2f) and the recording device 3.

First, the host computer 1 will be described. The host computer 1 measures data 5 (5a to 5f) transmitted from a plurality of measurement points via a communication line or the like.
And the received measurement data 5
, And sends it out to the terminal device 2 via the first connection line 61. Here, one of the predetermined processes is a process of adding identification information to measurement data. The identification information is information for specifying a terminal device to store the measurement data. For example, when the identifier "1" is added as the identification information, the measurement data is stored in the first terminal device 2a. When the identifier "6" is added as the identification information, the measurement data is It is stored in the sixth terminal device 2f. Then, the host computer 1 sends the measurement data 5a from the first measurement point to the first terminal device 2a, the measurement data 5b from the second measurement point to the second terminal device 2b,.
Specify the terminal device to be stored corresponding to each measurement point, such as.

Next, the terminal device 2 will be described with reference to FIG. Since the terminal devices 2a to 2f have the same configuration, the terminal device 2 will be described here. The terminal device 2 includes a display device 21 typified by a CRT or an LCD, a main body 22, and a keyboard 2 as operation means.
And 3. The measurement data 5 transmitted via the first connection line 61 is input to the calculation unit 221 via an input interface (hereinafter abbreviated as input I / F) 223. The arithmetic unit 221 refers to the identifier attached to the measurement data 5 and determines whether or not the measurement data 5 has been transmitted to itself. Here, when it is determined that the measurement data 5 has been transmitted to itself, the arithmetic unit 221 stores the measurement data 5 on the hard disk 222. The hard disk 222 is not limited to this, but may be a magneto-optical disk or a large-capacity RA.
Any storage device such as M may be used. On the other hand, when it is determined in this determination operation that the measurement data 5 is transmitted to another terminal device, the arithmetic unit 22
1 ignores this measurement data. The arithmetic unit 221 also includes:
Here, the acquired measurement data 5 is subjected to arithmetic processing and transmitted to the display device 21. Thus, the measurement data 5 is displayed on the display device 21 as the waveform information 211. The display device 21 displays the latest waveform information for a predetermined period T from the current measurement time. The measurement data stored in the hard disk 222 is output to the output I / F 22 for each predetermined unit amount.
The buffer 4 (FIG. 1)
Reference). The buffer 4 temporarily stores the sent measurement data and sends it to the recording device 3. As will be described in detail later, this sending operation is given a predetermined time lag to each of the terminal devices 2a to 2f, so that the recording device 3 is used efficiently. When sending measurement data,
The arithmetic unit 221 sends identification data to the measurement data and sends the data. The identification information here is the same as the above-mentioned identification information, and the first terminal device 2a assigns the identifier “1”
The second terminal device 2b attaches identification information corresponding to each terminal device to the identifier “2”, such as.

The keyboard 23 is for inputting operation information from an operator. Characteristic operations in the present system include interrupt recording operation and storage of measurement data.
Interrupt recording is a process of preferentially recording measurement data of a target terminal device. In the present system, each terminal device sends measurement data to the recording device 3 in a predetermined order, so that the recording device is used effectively. With this configuration, when an abnormality occurs in the measurement data, the measurement data may not be recorded immediately. In particular, if an abnormality occurs in the measurement data of the terminal device 2 immediately after sending the measurement data to the recording device 3, the measurement data will not be recorded until the order has completed one cycle. The interruption recording is made for such a problem, and is a process of preferentially recording measurement data of a specific terminal device. When this process is selected, the arithmetic unit 221 adds identification information indicating an interrupt process to the measurement data to be sent. This interrupt operation will be described later. Saving the measurement data is an operation of storing the measurement data for a predetermined period in another medium such as a floppy disk (FD). When receiving the operation information for storing the measurement data from the keyboard 23, the calculation unit 221 extracts the measurement data for the predetermined time T from the hard disk 222 and sends it to the FD drive 225. FD drive 225
Is the FD (not shown) that holds the measurement data inside
To be stored.

A clock 227 is provided for associating the input measurement data with the measurement time, and is incorporated in each of the terminal devices 2a to 2f. Arithmetic unit 22
1 refers to the clock 227 to attach time information (measurement time) to the measurement data stored in the hard disk 222 and send it to the buffer 4. Since this clock 227 is operated by the operation clock of the arithmetic unit 221, when the system is operated for a long time, each of the terminal devices 2 a to 2
The time sometimes fluctuated every f. This time shift hindered accurate measurement recording. The time adjusting unit 24 is a unit provided to match the time of the clock 227 built in each terminal device 2.
2 and a converter 241. Antenna 24
2 receives a time signal 6 from an external device (not shown),
This time signal 6 is input to the converter 241. Converter 24
1 receives the time signal 6 and generates a reset signal, and inputs the signal to the arithmetic unit 221 via the I / F 226. The arithmetic unit 221 that has received the reset signal operates the clock 2
The time 27 is adjusted to a predetermined time. Specifically, the time signal 6 is 0:00:00, 1:00:00,.
・ It is a signal transmitted at every predetermined time,
When the time signal is input, the arithmetic unit 221 performs an operation of changing the time of the clock 227 to the predetermined time.
Actually, the amount of deviation of the clock 227 every hour is extremely small, so that the clock 227 of each terminal always indicates the same time by the time adjusting means 24.

Next, the recording device 3 will be described with reference to FIG. The recording device 3 includes a sorter 31, a recording unit 32, and a transport unit 33, and is a device that performs recording on both sides of a single-sheet recording paper 34. The sorter 31 includes a plurality of trays 311 (311a to 311g) and wings 312 (312a to 312g) disposed at an end of the tray 311. The tray 311 is the recording paper 3 on which recording has been performed.
4, a first tray 311a is a recording paper 34a on which measurement data of the first terminal device 2a is recorded, and a second tray 311b is a recording paper on which measurement data of the second terminal device 2b is recorded. 34b,..., Each tray 311 holds the recorded paper of each corresponding terminal device 2. The tray 311g is a tray that holds the recording paper 34g recorded by the interrupt processing. As a result, the measurement data subjected to the interrupt processing can be immediately taken out, thereby improving work efficiency. The wings 312 form a passage for the recorded recording paper 34, and are driven to rotate based on a control signal from a signal generation unit 321 described later, and select the recording paper 34 on which the corresponding measurement data of the terminal device 2 is recorded. To the tray 311. The recording unit 32 records the recording paper 3 based on the measurement data transmitted from the terminal device 2.
4 is recorded. The recording unit 32 generates dot data used for recording and a drive signal for driving the platen 323 based on the measurement data sent from the terminal device 2 and temporarily stored in the buffer 4, and records based on the identification information. Tray 31 for storing completed recording paper 34
A signal generation unit 3 that generates a tray selection signal for selecting 1, etc.
21, a recording head 322 that forms a visible image on the recording paper 34 by a signal from the signal generation unit 321, and a transport unit 3 that is provided to face the recording head 322 and that will be described later.
3, and a platen 323 that conveys the recording paper 34 in cooperation with the recording paper 34. The transport unit 33 selectively switches the stocker 331 for storing and holding the recording paper 34, the reversing tray 332 for reversing the recording paper 34, and the path of the recorded recording paper 34 to the sorter 31 side or the reversing tray 332 side. And a wing 333.

The measurement data once stored in the buffer 4 is input to the signal generator 321 via the input I / F 327. The signal generation unit 321 generates dot data to be print data, drive data for the platen 323, drive data for the wings 312, and transport data based on the measurement data, and transfers these data to the print head 322, platen 323, and wings 312, respectively. And to the transport unit 33. Upon receiving the data from the signal generation unit 321, the transport unit 33 first takes out the recording paper 34 stored in the stocker 331 and transports it to the recording head 322. The recording head 322 performs recording on the recording paper 34 based on the dot data. At this time, platen 3
Reference numeral 23 denotes a recording paper 3 synchronized with the recording operation of the recording head 322.
4 is conveyed. The recording paper 34 on which recording by the recording head 322 has been completed is selectively transferred to the sorter 31 or the reversing tray 332 by the wings 333. That is, when the recording on one side is completed, and there is dot data for the next page and thereafter, the recording paper 34 is
Transferred to 2. On the other hand, when recording is performed on both sides of the recording paper 34, or recording is performed on one side,
If there is no dot data for the next page, the recording paper 34 is transferred to the sorter 31. In the reversing tray 332, the recording paper 34 is reversed. Then, the inverted recording paper 34 is conveyed to a position below the recording head 322, and recording is performed on the back surface. On the other hand, the recording paper 34 conveyed to the sorter 31 is held on a tray 311 defined by the wings 312.

Next, the operation of the exemplified system will be described. In the illustrated system, six terminal devices 2a
2f transmit predetermined amounts of accumulated measurement data to the recording device 3 at predetermined intervals. FIG. 4 is a timing chart showing the operation of the recording device 3 and shows the operation time for recording the measurement data transmitted by each of the terminal devices 2a to 2f. Each of the terminal devices 2a to 2f stores the measurement data on the hard disk 222 for two hours from the start of measurement.
a to 222f (see FIG. 2). Then, two hours after the start of the measurement, the first terminal device 2a sends out the measurement data for two hours to the recording device 3. The recording device 3 records this measurement data in about 8 minutes (period A). Next, 20 minutes after the recording of the first terminal device 2a starts, the second terminal device 2b sends out the measurement data for 2 hours from the start of the measurement to the recording device 3, and the recording for the measurement data is performed (period). B). Similarly, each terminal device sends out measurement data every 20 minutes, and the measurement data is recorded. When the recording (period C) is performed by the sixth terminal device 2f, the measurement data of the first terminal device 2a for 2 to 4 hours is recorded at the next timing (period D). In this system, the recording device 3 is configured to record measurement data from the terminal devices 2a to 2f usually every 20 minutes.

Next, interrupt processing in this system will be described with reference to FIG. It is assumed that the interruption operation of the fifth terminal device 2e (indicated by an arrow in the figure) and the interruption operation of the sixth terminal device 2f (indicated by the arrow) are successively performed around 2 hours and 23 minutes after the start of the measurement. . By this operation, the fifth terminal device 2e and the sixth terminal device 2
f extracts measurement data displayed on the screen at the time of operation, that is, data for a predetermined time T from the latest data from the hard disk 222 and sends it out. In the illustrated system, the predetermined time T is set to one hour. In this case, the terminal devices 2e and 2f transmit the measurement data after 1 hour and 23 minutes after the start of the measurement by this interrupt operation. By the way, at the time of this interruption,
The recording device 3 records the measurement data of the second terminal device 2b. In this case, the transmitted measurement data is stored in the buffer 4
(See FIG. 1). Then, after the recording of the measurement data of the second terminal device 2b is completed, these measurement data are recorded continuously (period E). Note that the fifth terminal device 5e starts 3 hours and 20 minutes later, and the sixth terminal device runs 3 hours and 4 minutes.
A normal recording operation is performed after 0 minutes. In this recording operation, measurement data for 2 hours is recorded regardless of the presence or absence of the interrupt processing. Therefore, the measurement data recorded by the interrupt processing is recorded in duplicate with the measurement data of the normal recording, and it becomes very easy to extract the data at the time of occurrence of an abnormality from the data for storage.

Next, a case where an interrupt operation is performed from many terminal devices will be described. Four hours and five minutes after the start of the measurement, the sixth terminal device 2f, the fourth terminal device 2d,
It is assumed that an interrupt operation is performed in the order of the fifth terminal device 2e and the third terminal device 2c. In this case, the first terminal device 2a
Following the recording operation, recording is performed in the order of the sixth terminal device 2f, the fourth terminal device 2d, the fifth terminal device 2e, and the third terminal device 2c (period F). By the way, after starting the measurement 4
Recording of the measurement data of the second terminal device 2b should be performed from time 20 minutes, but in this system, recording by interrupt processing is prioritized. This is due to the high urgency of the measurement data for interrupt processing. For this priority processing, the present system uses a large-capacity buffer 4 or hard disk 222 so that no data is lost due to interrupt processing.

Although a system in which six terminal devices 2 are provided and one recording cycle is two hours has been described above, the present invention is not limited to this. For example, a system configuration in which the number of the terminal devices 2 is 20 and the recording cycle is 4 hours may be adopted.
Further, in the illustrated system, identification information for designating a terminal device is added to the measurement data batch-input to the host computer 1, and the measurement data is transmitted to each of the terminal devices 2 a to 2 f via the connection line 61. However, this may be configured so that the host computer 1 and each of the terminal devices 2a to 2f are connected by individual connection lines. In this case, the host computer 1 recognizes the measurement point of the input measurement signal and sends it to the corresponding terminal device 2. Therefore, the operation of providing the identification information at the stage of transmitting the measurement data from the host computer 1 to each terminal device 2 becomes unnecessary.
