Abstract

PROBLEM TO BE SOLVED: To provide a sample analyzer capable of notifying the device state to a place other than a room where the analyzer is installed, without preparing exclusive hardware or software for a computer network. SOLUTION: When an EPMA body is started, an analysis control means 3 recognizes the state of the EPMA body in every fixed time, and sends data showing the state to a device state Html-forming means 4. The Html-forming means 4 makes a file of the data in the Html form. The file in the Html form is memorized in a memory part 5. A Web browser is integrated in a personal computer 10, and an operator uses the Web browser and designates an address (URL) given to a server 6, and thereby accesses the server 6 and designates a required file, to be able to read a device state file memorized in the memory part 5 through the server 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sample analyzer such as an electron probe microanalyzer (EPMA).

[0002]

2. Description of the Related Art EPMA irradiates a sample with an electron beam,
By detecting characteristic X-rays generated from the sample by the irradiation,
It is a device that performs qualitative and quantitative analysis of a sample.

When confirming the state of the EPMA apparatus (electron beam setting state, spectroscope setting state, exhaust system state, sample stage position, etc.), it is fundamental that an operator goes to the front of the apparatus.

However, in recent years, computer networks have become widespread, and if dedicated hardware and software are prepared for the purpose, an operator can know the state of the apparatus from a room other than the room where the apparatus is installed. Was.

[0005]

However, it is costly to prepare such dedicated hardware and software, and the operator knows the state of the apparatus unless it is in a place where they are already prepared. I couldn't do that.

[0006] The present invention has been made in view of such a point, and its object is to provide a computer network without preparing dedicated hardware and software.
An object of the present invention is to provide a sample analyzer capable of knowing the state of an apparatus even from a room other than the room where the apparatus is installed.

[0007]

Means for Solving the Problems A sample analyzer according to the present invention for achieving the above object has a means for filing data representing the state of the apparatus in a predetermined format, and a storage means for storing the filed data. Server means for exchanging data with another computer connected to the network, and transmitting data stored in the storage means via the server means in response to a request from the computer connected to the network. It is configured to be.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an example of the sample analyzer of the present invention, and is a diagram showing an example in which the present invention is applied to EPMA.

In FIG. 1, reference numeral 1 denotes an EPMA main body;
The EPMA main body 1 includes an electron gun, an electron lens, an optical microscope, an X-ray detector, and the like.

Reference numeral 2 denotes a CPU.
It is connected to the. The CPU 2 includes an analysis control unit 3 for controlling the EPMA main body 1 and a device state Html conversion unit 4.
, A storage unit 5 and a server 6.

The CPU 2 is connected to input means 7 and a display device 8 for displaying analysis results and the like, and is further connected to personal computers 10 and 11 via a LAN 9 via a network. The personal computers 10 and 11 are installed in a room different from the room where the EPMA body 1 is installed.

In such a configuration, when the operator instructs the activation of the apparatus by the input means 7, the analysis control means 3 activates the EPMA main body 1.

When the EPMA main body 1 is started, the analysis control means 3 recognizes the state of the EPMA main body 1 (electron beam setting state, spectroscope setting state, exhaust system state, sample stage position, etc.) at regular intervals. The data representing the state is sent to the apparatus state Html conversion means 4.

The Html conversion unit 4 converts the data indicating the device status transmitted from the analysis control unit 3 into a file in the Html format. The HTML format file is stored in the storage unit 5 and its contents are overwritten each time the analysis control unit 3 recognizes the device state. The apparatus state recognition by the analysis control means 3 is performed during the sample analysis in the EPMA main body 1.

FIG. 2 is a flowchart showing the operation of the apparatus shown in FIG.

By the way, in recent computers, especially personal computers, browsing software (Web browser) necessary for using the Internet is almost standard incorporated. For this reason, if the operator accesses the server 6 by specifying the address (URL) assigned to the server 6 using the Web browser of the personal computer 10 or 11, and specifies a necessary file, the storage unit 5 can be browsed via the server 6.

As described above, in the apparatus shown in FIG. 1, the state of the apparatus can be known from a room other than the room where the apparatus is installed, without preparing dedicated hardware and software as in the related art.

As described above, an example of the present invention has been described using the apparatus of FIG. 1, but the present invention is not limited to this.

For example, in the above example, the data indicating the device status is overwritten at regular intervals, but only the data that has changed during the constant time may be rewritten by converting the data into an HTML file. In that case, the analysis control means 3
Compares the newly recognized device status with the device status stored in the storage unit 5 and determines only the content that does not match is the Html
What is necessary is just to operate so that it may send to the conversion means 4.

Alternatively, the analysis control means 3 may send data indicating the apparatus state to the Html-forming means 4 only when the state of the apparatus changes, not at regular intervals.

Various data such as the usage time and the user name input from the input means 7 as well as the state of the apparatus may be converted into an HTML file.

The file is not limited to the HTML file, and may be any file that can be displayed by a Web browser.

Further, the sample analysis program converted into HTML is stored in the storage unit 5 in advance, and the server 6 is accessed using a Web browser of a personal computer, and an instruction to start the sample analysis program is sent to the server 6. You may give it through.
