[Prior Art]

 2. Description of the Related Art As an automatic continuous measuring device, there is known an automatic continuous measuring device including a measuring device for continuously measuring and a recording device for continuously recording a measurement result obtained by the measuring device on a recording paper.

The time is preliminarily printed and printed on the recording paper used in this automatic continuous measuring device, and the recording paper is set on the recorder so that the time displayed on the recording paper and the actual measurement time match. As a result, it is possible to know what time the measurement result recorded on the recording paper is. Therefore, if the power supply to the device is interrupted due to a power failure or accident during the automatic continuous measurement, and the paper feed of the recording paper is interrupted during that time, when the power supply is restored and the automatic continuous measurement is restarted. In addition, the time displayed on the recording paper will not match the actual measurement time, making it impossible to analyze the measurement results accurately.

For this reason, conventionally, when the power supply to the apparatus is interrupted due to a power failure or the like, the recording paper is advanced to eliminate the difference between the actual measurement time and the display time of the recording paper. A paper feeding means such as is adopted. a. A method in which the backup battery is built into the recorder and the recording paper is fed by this backup battery in case of power failure. B. The recorder has a built-in clock backed up by a battery, which measures the time from when the power supply was stopped until the power supply was restored, and at the same time the power supply was interrupted when the power supply was restored. To fast forward the chart paper

[0005]

[Problems to be solved by the device]

 However, since the above-mentioned paper feeding means (a) feeds the recording paper by the backup battery when the power supply is interrupted, a large battery is required and the cost becomes high. In addition, even if a large battery is used, there is a limit to the time that paper can be fed, and if the power supply is interrupted for a long time, paper cannot be fed.

Further, the paper feeding means of (b) measures the time when the power supply is interrupted by the clock built in the recorder and automatically fast-forwards the recording paper for that time when the power supply is restored. Since it is configured in this way, even if the power supply is interrupted due to a power failure during automatic continuous measurement, or if the power is turned off for maintenance etc., it will be treated exactly the same and recorded as the latter. There is a problem that fast-forwarding is performed even when it is unnecessary to fast-forward the paper. That is, in an automatic continuous measuring device, maintenance is performed by periodically turning off the power to supplement or replace consumables.In such a case, set the recording paper to the time after the maintenance is completed. Therefore, there is no need to fast forward when the power is turned on. However, even in such a case, since the recording paper is fast-forwarded by the paper feeding means of (b), the operator has to perform extra work of setting the recording paper again to the current time.

[0007] The present invention, when the power supply to the device is stopped, and then the power supply is restored, whether the power supply is unintentionally stopped due to power failure, accident, etc. during automatic continuous measurement, maintenance, etc. It is determined whether the power supply has been artificially stopped by turning off the power for the purpose of automatic power supply.When the power supply is restored, the chart paper is fast-forwarded in the former case and not in the latter case. An object is to provide a continuous measuring device.

[0008]

[Means and Actions for Solving the Problems] In order to achieve the above-mentioned object, the present invention, as shown in FIG. 1, has a measuring instrument having a measuring section for continuously measuring, and a recording paper feed. In an automatic continuous measuring device that consists of a recorder having a mechanism, transmits the measurement results obtained by the above-mentioned measuring unit from the measuring instrument to the recorder and continuously records the measurement results on the recording paper, the measuring unit Operating state detecting section for detecting the operating state of the measuring section, an operating state storing section for storing the operating state of the measuring section detected by the operating state detecting section, and an operating state and / or operation of the measuring section detected by the operating state detecting section.

Time measurement unit and the paper feed signal To provide an automatic continuous measuring apparatus, wherein the paper feed mechanism is provided with a paper feeding mechanism control unit that controls to fast forward the recording paper of a length corresponding to the power supply interruption time upon receipt.

In the device of the present invention, the configurations of the measuring instrument and the recording instrument are not limited. For example, the measuring instrument can be provided with a measuring section for performing arbitrary measurement of the concentration of a specific component (for example, the concentration of SO ₂ or dust in the atmosphere), pH, conductivity, etc. Not limited. Further, the configurations of the operation state detection unit, the operation state storage unit, the paper feed signal generation unit, the time measurement unit, and the paper feed mechanism control unit are not limited. These may be configured by one device or may be configured by a plurality of devices. Further, the measurement operation state of the measurement unit detected by the operation state detection unit includes, for example, the switch state of the meter, the measurement mode state of the meter, the switch state of the power switch, and the like. Examples of the paper feed signal transmitted to the feed mechanism control unit include, but are not limited to, a communication command, an on / off signal (contact), and the like.

In the device of the present invention, the operating state detecting section detects the measured operating state of the measuring section when the power supply is stopped, the measured operating state is stored in the operating state storing section, and the operating state detecting section detects the operating state. Detects the measurement operation status of the measurement unit when the power supply is restored. In addition, when the power supply is restored, the paper feed signal generation unit stores the measured operation state of the measuring unit stored in the operation state storage unit when the power supply is stopped and / or the power supply detected by the operation state detection unit when the power supply is restored. Based on the measurement operation status of the measurement unit, determine whether the power supply was unintentionally stopped due to a power failure during automatic continuous measurement, or the power was artificially turned off for maintenance. In the former case, that is, when the recording paper needs to be fast-forwarded, a paper-feeding signal is sent from the paper-feeding signal generating unit to the paper-feeding mechanism control unit to fast-forward the required amount of recording paper in the recorder. On the other hand, in the latter case, that is, when the fast-forwarding of the recording paper is not necessary, the paper-feeding signal is not transmitted from the paper-feeding signal generator to the paper-feeding mechanism controller. Note that the above determination method may be any method according to the measurement operation state to be detected, and is not particularly limited.

【Example】

Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited to the following examples. Embodiment 1 FIG. 2 shows an automatic continuous measuring apparatus according to an embodiment of the present invention, which is an example of detecting a switch state of a measuring instrument as a measuring operation state. In the figure, 1 indicates a measuring instrument and 2 indicates a recording instrument. The measuring instrument 1 is provided with the above-mentioned measuring section, operation state detecting section, operation state storing section and paper feed signal generating section, and the recorder 2 is provided with the above-mentioned time measuring section and paper feed mechanism control section. Has been.

In the measuring instrument 1, 3 is a power switch for turning the power on and off, 4 is a measurement mode switch for switching the measurement mode to automatic (A) or manual (M), and 5 is an invalid measurement value. This is an adjustment switch for setting the adjustment mode (T) that informs that. Each of these switches 3, 4, and 5 is formed by a toggle switch that stops at the switched position, and the switch states can be stored mechanically. The time measuring unit of the recorder 2 includes a clock, a backup battery for backing up the clock when the power is turned off, a storage operation device having a storage function of time measured by the clock and a calculation function based on the time. It is composed by. Incidentally, reference numeral 6 in the figure is a recording paper.

When performing automatic continuous measurement with this apparatus, the power switch 3 is set to the on side, the measurement mode switch 4 is set to the automatic (A) side, and the adjustment switch 5 is set to the non-adjustment mode side. Then, the measuring unit carries out automatic continuous measurement, and the obtained measurement result 7 is transmitted to the recorder 2. The recorder 2 receives the measurement result 7 and continuously records it on the recording paper 6. The measurement result is also sent to the central computer at the same time. Further, when the measurement meter 1 is adjusted, the power switch 3 is set to the on side, the measurement mode switching switch 4 is set to the manual side (M), and the adjustment switch 5 is set to the adjustment side (T). When performing maintenance, set the power switch 3 to the off side and turn off the power.

In this device, when the power supply to the measuring meter 1 and the recording meter 2 is stopped, the states of the switches 3, 4, and 5 of the measuring meter 1 are detected by the operating state detecting section, and the operating state storage section is used. Remember. Further, the time measuring unit of the recorder 2 stores the time. Next, when the power supply is restored, the operating state detection unit detects the states of the switches 3, 4, and 5 of the measuring instrument 1, and the paper feed signal generation unit stores and stores the switch state when the power supply is restored. Compare it with the switch state when the power supply was stopped stored in the section. If the switch state when the power supply is stopped is the switch state for automatic continuous measurement, and the switch state when the power supply is restored is also the switch state for automatic continuous measurement, there is a power failure during automatic continuous measurement. It is determined that the power supply has been unintentionally stopped, and the paper feed signal generator sends the paper feed signal 8 to the paper feed mechanism controller of the recorder 2. In addition, if the switch state when the power supply is stopped and the switch state when the power supply is restored are other than the above combinations, it is determined that the power was artificially turned off for maintenance etc., and the paper feed signal is transmitted. Absent.

When the recorder 2 receives the paper feed signal 8, the time measuring unit calculates the time during which the power supply is interrupted based on the power supply restoration time and the stored power supply stop time, The feed mechanism fast-forwards the recording paper of a length corresponding to the time, and the actual measurement time and the time displayed on the recording paper are matched. In this case, if the interruption of the power supply is more than one day, the hours and minutes displayed on the recording paper are set as the actual measurement time by fast-forwarding the recording paper for the fractional hours that exceed the number of days. You may make it match.

Embodiment 2 FIG. 3 shows an automatic continuous measuring apparatus according to another embodiment of the present invention, which is an example of detecting the measurement mode state of a measuring instrument as a measurement operation state. In this device, the measuring device 1 is provided with seven key switches 9a to 9g of a type that returns to the original state when the finger is released after being pressed, instead of the toggle switch of the device of the first embodiment. Power on / off switching, measurement mode switching, adjustment mode setting, etc. are performed. The rest of the configuration of this device is the same as that of the embodiment of FIG. 2, so the same reference numerals are given to the same components and the description thereof is omitted.

In the present device, since the key switches 9a to 9g are used, the measurement operation mode when power supply is restored cannot be determined from the state of the switch, so the measurement operation mode when power supply is stopped is detected by the operation state detection unit. It is detected and stored in the operating state storage unit. Further, the time measuring unit of the recorder 2 stores the time at that time. Next, when the power supply is restored, the measurement operation mode when the power supply is stopped stored in the operation status storage unit in the paper feed signal generator is checked, and the measurement mode when the power supply is stopped is automatically measured continuously. If it is in the mode, it is determined that the power supply was unintentionally stopped due to a power failure during automatic continuous measurement, and the paper feed signal generation unit sends the paper feed signal 8 to the paper feed mechanism control unit of the recorder 2. To do. If the measurement mode when the power supply is stopped is not the automatic continuous measurement mode, it is determined that the power was artificially turned off for maintenance or the like, and the paper feed signal is not transmitted. When the recorder 2 receives the paper feed signal 8, the recording paper is fast-forwarded as in the first embodiment.

Embodiment 3 FIG. 4 shows an automatic continuous measuring apparatus according to still another embodiment of the present invention. This device is an example of detecting the power switch state of the measuring meter as the measurement operation state. In the apparatus, 10 is a measuring instrument control computer provided with the operating state detecting section, the operating state storing section, and the paper feed signal generating section, 11 is a power source section of the measuring instrument, and 12 is a power source voltage monitoring section. The power supply unit 11 communicates with the computer 10 and the power supply voltage monitoring unit 12, and the power supply voltage monitoring unit 12 communicates with the computer 10. Further, in the figure, 13 is a power switch of the power supply unit 11, 14 is a power cord connected to the power switch 13, and 15 is a contact interlocking with the power switch 13. The contact 15 communicates with the computer 10 and inputs the contact state to the computer 10.

In the present apparatus, the power supply voltage monitor unit 12 monitors the power supply voltage of the power supply unit 11, and when the power supply voltage of the power supply unit 11 drops, the power supply voltage drop signal 16 is transmitted to the computer 10 by an interrupt input. To do. When the computer 10 receives the power supply voltage drop signal 16, the operating state detecting unit detects the state of the contact 15 which is in the same state as the power source switch 13 in cooperation with the power source switch 13 and stores it in the operating state storage unit. .. Further, the time measuring unit of the recorder 2 stores the time at that time. Next, when the power supply is restored, the state of the contact 15 when the power supply is stopped stored in the operation state storage unit in the paper feed signal generation unit is checked, and the state of the contact 15 when the power supply is stopped is the power source. If it is on, it is determined that the power supply was unintentionally stopped due to a power failure during automatic continuous measurement, and the paper feed signal generator sends the paper feed signal 8 to the paper feed mechanism controller of the recorder 2. To do. If the contact 15 is in the power-off state when the power supply is stopped, it is determined that the power is artificially turned off for maintenance or the like, and the paper feed signal is not transmitted. When the recorder 2 receives the paper feed signal 8, the recording paper is fast-forwarded as in the first embodiment.

As described above, in the automatic continuous measuring devices of Examples 1 to 3, when the power supply to the measuring instrument 1 and the recorder 2 is stopped, the power is unintentionally supplied due to a power failure or the like during the automatic continuous measurement. The paper feed operation in the recorder stops even when the power is turned off for maintenance or other reasons, but when the power supply is stopped unintentionally during automatic continuous measurement. When the power supply is restored, the recording paper can be fast-forwarded to match the actual measurement time with the time displayed on the recording paper, while the power is turned off when the power is artificially turned off for maintenance. There is no need to fast forward the chart paper when the supply is restored.
