Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various analyzers including a gas analyzer.

[0002]

2. Description of the Related Art Recently, a microcomputer has been attached to an analyzer to perform various controls and processing of analysis data. For example, in an outdoor environment or a site where environmental conditions are not so good, unattended Continuous measurements are taken. As described above, in recent analyzers, control has been reliably performed, and analysis data can be reliably processed.

By the way, in an analyzer having such excellent equipment, an "alarm" is displayed or an "alarm" signal is output to the outside when an abnormality occurs in the analyzer. It is common and the actual failure point cannot be found without actually checking each part of the device, but since it is an unmanned operation, the number of maintenance personnel and maintenance is small, and because it is a continuous measurement, it is for inspection etc. It is often difficult to stop the measurement easily.

On the other hand, as described above, in the above-mentioned analyzer, it is necessary to minimize the time during which measurement is interrupted or stopped (at most about several hours).

[0005]

On the other hand, recently,
A method of estimating the failure mode from the abnormal phenomenon of the analyzer is being studied, but at present, its judgment is not easy.

Further, it is conceivable that most of the information from the analyzer is displayed on the display section provided in the central monitoring station for monitoring various control information including the information from the analyzer.
In such a case, it becomes difficult to recognize them in detail, and displaying too much information may be a minus.

The present invention has been made in consideration of the above matters, and an object thereof is to easily search for details of the information while displaying maintenance information so that the operating status of each part of the apparatus can be grasped at a glance. It is an object of the present invention to provide an analyzer capable of performing the above.

[0008]

In order to achieve the above object, according to the present invention, in an analyzer equipped with a display device, maintenance information relating to specific parts or functions of the entire device is displayed on the screen of the display device. , Main mode,
It is possible to switch and display each main part mode of the main part and each part mode of each main part.

DETAILED DESCRIPTION OF THE INVENTION The details of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example in which the present invention is applied to an apparatus for measuring the concentration of CO ₂ in the atmosphere. In FIG. 1, reference numeral 1 is a sample gas inlet, which is a sample connected to the inlet. In the line 2, the filter 3, the pump 4, the pressure sensor 5, the three-way solenoid valve 6, the electronic cooler 7, the flow meter 8,
A gas analyzer 9 is provided. Further, 10 is a calibration gas cylinder connected to the three-way solenoid valve 6 via the on-off valve 11, and 12 is a pressure gauge for displaying the gas pressure in the cylinder. Reference numeral 13 is a drain pot connected to the electronic cooler 7.

Reference numeral 14 denotes a microcomputer, which receives signals from the respective parts of the apparatus via the interface 15 to perform a predetermined calculation and appropriately output a control signal based on the calculation result. That is, in the interface 15, the detection output of the pressure sensor 5, the temperature signal of the electronic cooler 7, the detection output of the flow meter 8, the measurement signal from the detector of the gas analyzer 9, the pressure signal from the gas pressure gauge 12, etc. Is entered.

Reference numeral 16 is a keyboard as an input device of the microcomputer 14, and 17 is a CR as a display device.
T and 18 are storage devices.

On the screen of the display device 17 of the analyzer, a main part mode screen including the part related to a specific part to be subjected to the failure mode or the function of the entire device, and each main part mode of the main part are displayed. Prepare the screen and the parts mode screen for each main part, and
Has a function of appropriately switching these screens.

The operation of the above analyzer will be described with reference to FIGS.
It will be explained with reference to also. Now, for example, the deterioration of the valve of the pump 4 of the sampling system will be described as an example.
As shown in, the screen A showing the operation status of the analyzer is displayed, and the information 21 "inspection required" is displayed. In this example, the characters are surrounded, but the characters may be brightened or blinked. Then, the information 22 "normal" is displayed when the device is operating normally, and the information 23 "abnormal" is displayed when an abnormality occurs.

On the screen A, when the user points to the portion 21 indicated as "need to be checked", the screen is switched to the main part mode screen B as shown in FIG. Then, the information 31 of "abnormality occurrence" is displayed on the "sampling system" which is one of the main parts.

Instead of the information of "abnormality occurrence", "maintenance preparation is necessary (in normal operation, for example, when there is a high possibility that an abnormal state will occur after about two weeks)", More specific information may be displayed.

Then, in the screen B, when the point is put on the portion 31 displayed as "abnormality occurrence", as shown in FIG.
The screen is switched to each main part mode screen C of the main part as shown in FIG. Then, the information 41 "flow rate abnormality" that more specifically represents the content of the abnormal state is displayed.

Further, in the screen C, when the point is applied to the portion 41 displayed as "abnormal flow rate", as shown in FIG.
Mode screen D showing the main parts and functions as shown in
Switch to. And "deterioration of the sampling pump"
Such information 51 is displayed. In this case, more specific information such as “necessary to replace the sampling pump valve” may be displayed.

As can be understood from the above description, in the analyzer of the present invention, an abnormal state or the like at a certain part of the device (in this case, the pump 4 of the sampling system) can be resolved without disassembling the part. Judgment can be made and necessary treatments can be instructed.

In the above embodiment, the operating time of the pump 4 is managed by the microcomputer 14,
In addition to the above "requires replacement of the sampling pump valve", "requires replacement of the sampling pump valve" and "requires replacement of the sampling pump body" at regular intervals.
For example, the failure mode may be prepared, and in such a case, by sequentially displaying the information, the setting of the maintenance period of the entire device can be displayed together.

Furthermore, by displaying the input data from each part of the analyzer to the interface together with the normal range, it becomes possible to quantitatively grasp the state of each part.

[0022]

As described above, according to the present invention, the operating status of each part of the analyzer can be grasped as a whole, and then the screen can be switched to know the details in more detail. . Therefore, when an abnormality occurs, it is possible to investigate the above-mentioned parts of the analyzer step by step and grasp the cause in a short time.

Then, information of a notice level that does not lead to maintenance requiring replacement of parts can be obtained from the screen, and by this, preparation of parts necessary for maintenance and arrangement of the parts based on the stock status thereof can be obtained. You can judge the need. In addition, in a normal state, it is possible to check the state of parts and devices of each part of the device.

As described above, according to the present invention, it is possible to easily search the details of the information while displaying the maintenance information so that the operating status of each part of the analyzer can be grasped at a glance. It has a great effect on the maintenance and management of analyzers installed in sites where environmental conditions are not so good.
