[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-channel measurement unit that collects and measures analog data in combination with a personal computer.

[0002]

[Prior art]

 Conventionally, as this type of multi-channel measurement unit, a structure shown in FIG. 3 has been known. In FIG. 3, reference numeral 10 is a multi-channel measurement unit. The front panel of the multi-channel measurement unit 10 is provided with connector terminals 11 for collecting and measuring a large amount of measurement data, and the multi-channel measurement unit 10 has a multi-channel measurement unit. A measurement unit bus (hereinafter referred to as MS bus) 12 is derived. A bus converter 14 is provided at the end of the MS bus 12. By inserting the bus converter 14 into an expansion slot 18 of a desktop personal computer 16, the multi-channel measurement unit 10 can be installed in the desktop personal computer 16. It will be possible to send and receive for data collection and measurement by connecting with. That is, the multi-channel measurement unit 10 is controlled by software on the desktop personal computer 16 via the MS bus 12 and can collect and measure desired measurement data. The multi-channel measurement unit 10 can be connected to the expansion units 24, for example, up to 16 units.

FIG. 4 is a block diagram showing these connection relationships. As shown in FIG. 4, the measurement unit 10 is connected to the expansion slot 18 of the personal computer 16 via the bus converter 14 and the MS bus 12, and the MS bus 12 is used for analog / digital (A / D) conversion. Connected to the container 26. The measurement unit 10 and the extension unit 24 are connected by the MS bus 13. In the measurement system configured in this way, the software on the personal computer 16 controls the multi-channel measurement unit 10 and the extension unit 24 via the bus converter 14, and the A / D converter 26 digitally converts the analog signal data. It can be converted into signal data and collected, and the collected data can be displayed on the display 28 of the personal computer 16 in real time and stored on the disk. The stored data can be reproduced on the display 28 of the personal computer 16.

[0004]

[Problems to be solved by the device]

 However, since the multi-channel measurement unit 10 described above is premised on using the expansion slot 18 of the desktop personal computer 16, it has become commercially available recently and has excellent portability. In the case of using a bus converter, since there is no expansion slot 18, it is necessary to separately prepare an expansion I / O box 20 and connect the bus converter 14 as shown in FIGS. That is, when the multi-channel measurement unit 10 is connected to the notebook personal computer 22 and is carried and used in various places such as outdoors, the expansion I / O box 20 connected to the bus converter 14 is connected to the notebook personal computer 22. 22 has the hassle of having to carry it with the user, and sometimes the power supply for the expansion I / O box 20 requires AC100V. There was a problem that it would be damaged.

Therefore, an object of the present invention is to connect and use a desktop personal computer, and when connecting and use a notebook personal computer, collect and measure measurement data without losing portability. It is to provide a multi-channel measurement unit capable of performing

[0006]

[Means for Solving the Problems]

 The multi-channel measurement unit according to the present invention is a multi-channel measurement unit that is controlled by software on a personal computer and collects and measures analog data via a bus converter, an analog / digital converter, and a multi-channel measurement bus. A bus converter for a portable notebook personal computer connected to the analog / digital converter and the multi-channel measurement bus is provided separately from the bus converter for the personal computer.

[0007]

[Action]

 According to the multi-channel measurement unit according to the present invention, the notebook-type personal computer bus converter is built in the multi-channel measurement unit, so that the notebook-type personal computer can directly perform multi-channel measurement without the expansion I / O box. Can be connected to the unit.

[0008]

【Example】

 Next, an embodiment of a multi-channel measurement unit according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram of a multi-channel measurement unit showing an embodiment of the present invention. The same components as those of the conventional example shown in FIG. 3 will be described with the same reference numerals. The multi-channel measurement unit 30 according to the present invention includes an MS bus 12 and a bus converter 14 as in the conventional multi-channel measurement unit 10, and also includes a desktop personal computer 16 or a notebook personal computer 22. A bus converter 32 for a notebook personal computer is further incorporated so that either one of them can be used. Therefore, the notebook personal computer 22 can be directly connected to the multi-channel measurement unit 30 without the expansion I / O box 20.

FIG. 2 is a block diagram showing these connection relationships. As shown in FIG. 2, the multi-channel measurement unit 30 includes an A / D board 34, a notebook personal computer bus converter 32, an MS bus 36 connecting them, and the like, and a desktop personal computer 16 Are connected by inserting the bus converter 14 connected to the end of the MS bus 12 coming out of the A / D board 34 into the expansion slot 18 of the desktop personal computer 16 as in the conventional case. When connecting to the notebook personal computer 22, the expansion bus output 38 of the notebook personal computer 22 may be directly connected to the terminal of the notebook personal computer bus converter 32 of the multi-channel measurement unit 30. Of course, this multi-channel measurement unit 30 can also be connected to the expansion unit 24 via the MS bus 13 as in the conventional case.

[0011]

[Effect of device]

 As is apparent from the above-described embodiments, according to the present invention, by incorporating a bus converter for a notebook personal computer in the multi-channel measurement unit, it is possible to expand the connection when the notebook personal computer is connected. It can be directly connected to the multi-channel measurement unit without going through the I / O box. As a result, the portability of the extended I / O box for carrying out measurements at various locations such as outdoors is eliminated and portability is improved. In addition, the user does not have to purchase an expansion I / O box, and one multi-channel measurement unit can be used for both desktop personal computers and notebook personal computers, which is economical. .

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various design changes can be made without departing from the spirit of the present invention. Of course.
