Abstract

PURPOSE:To facilitate the collection of data at scattered measuring points, by separately constituting a measuring unit and a regeneration unit and imparting the operation parameter of the measuring unit from the regeneration unit. CONSTITUTION:In a measuring unit M, a sensor 1 such as a thermocouple is connected to the terminals thereof and the measuring signal of the sensor 1 is amplified by an input circuit 3 and converted to a digital signal by an A/D converter 4 to be stored in a memory 6 as measured data by a control means 5. Further, the operation parameter of the measuring unit M corresponding to the kind and range of the sensor is imparted to the measuring unit M from a regeneration unit R to be stored in the memory 6. The whole of said measuring unit M or memory 6 is mounted to the regeneration unit R and the stored measured data is read by CPU8 operated by the set data of a setting means 9 and the program of a memory 10 to be displayed on a display device 11 and recorded on a recorder 12. By this method, the measuring unit M is made functionally simple and small-sized as possible to collect data and, subsequently, said data is recovered to be regenerated by the regeneration unit R.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data collection device that collects various types of data.

[Prior Art] In general, a data acquisition device called a data recorder takes in a plurality of input signals using an input switch, converts them into digital signals, and prints out the measured data using a printer or the like.

Problem 1 that this invention attempts to solveHowever,
Such data acquisition devices are large in size and cannot be used to measure a specific point outdoors, or to measure many measurement points over a wide area.
There are some inconveniences.

In view of the above points, it is an object of the present invention to provide a data collection device that can easily collect data from scattered measurement points, etc.

[Means for solving the problem 1] The present invention includes a measurement unit that converts a measurement signal detected by a sensor into a digital signal and stores it in a memory as measurement data, and a system that reproduces the measurement data stored in the memory of this measurement unit. This data collection device is equipped with a reproducing unit l-, in which both units are configured separately, and the operational parameters of the measuring unit are supplied from the reproducing unit.

[Embodiment] FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention.

In the figure, M is a measurement unit and R is a reproduction unit 1.
It is ~. In the measurement unit M, a sensor 1 such as a thermocouple is connected to a terminal 2, and the measurement signal of the sensor 1 is amplified by an input circuit 3, converted into a digital signal by an A-D converter 4, and then
U and other tli+ control means 5 store the measured data in a memory 6 such as a floppy disk or RAM. A predetermined operating voltage is supplied to these circuits from a power source 7 such as a battery, and the measurement unit M is made as small as possible.

The entire measuring unit M or the memory 6 is attached to the reproducing unit R, and the processing means 8 such as a CPU that operates based on the setting data of the setting means 9, the program of the memory 1o, etc.
The measurement data stored in the memory 6 is read out, subjected to predetermined processing, and displayed on the display means 11 or recorded on the recording means 12.

That is, before measurement, operational parameters of the measuring unit M according to the type, range, etc. of the sensor 1 of the measuring unit M are given to the measuring unit M from the reproducing unit R and stored in the memory 6 thereof.

This memory 6 or the entire measuring unit M can be collected and installed in the reproducing unit R to obtain data.

FIG. 2 shows a slightly more specific embodiment.

In FIG. 2(a), a sensor 1 such as a thermocouple is connected to a terminal 2 of a measuring unit M, and a RAM or the like backed up by a battery is used as a memory 6.
The whole thing is on cassette.

The measurement unit M itself having the RAM power set 1~ is attached to the attachment part 13 of the reproduction unit R shown in FIG. 2(d),
I am trying to play back the contents of memory.

FIG. 2(b) shows the sensor 1 of the measurement unit M, which includes a condensing part 1a, a fiber 1b, and a detection element 1C inside.
The radiation energy from the object to be measured is collected by the condensing unit 1a, transmitted through the optical fiber 1b, converted into an electrical signal by the detection element 1C, and the measurement data is stored in the memory 6 such as a floppy disk, and the measurement is performed. Value indicating means 1d
to be displayed. The memory 6 as a floppy disk of this measurement unit M is mounted on the mounting section 14 shown in FIG. 2 <d), and the data is reproduced.

In Fig. 3(C), a measuring unit M is attached to a moving object to be measured O using a magnet 1e, etc., and measurement data is obtained by a sensor 1 such as a temperature element provided integrally with the measuring unit M. Store in memory. Then, the measurement unit M is recovered and the memory contents thereof are reproduced by the reproduction unit R.

In addition, for measurement at multiple points, a large number of measurement units may be provided in a scattered manner, and the measurement units may be collected and the data may be reproduced after the measurement is completed.

[Effects of the Invention] As described above, in this invention, the measurement unit is made as simple as possible and miniaturized to collect data, which is then collected and regenerated by the regeneration unit. have advantages.

In other words, there is no need for large equipment such as a data logger, and it is extremely easy to collect a large number of measurement data scattered in the field, data on moving objects, etc. It is extremely easy to use with only one wire, and there is no need to route signal lines or power lines, making it possible to perform extremely flexible measurements at low cost. Furthermore, since the operating parameters of the measurement unit can be set arbitrarily, it can be used for various measurements.
