Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-site measurement data collection device, and more particularly to labor saving of measurement.

[0002]

2. Description of the Related Art Manufacturing lines such as an insulation resistance meter 2 for measuring the insulation resistance of a motor 1 as shown in FIG. 3 and a thermometer 4 for measuring the temperature of a transformer 3 as shown in FIG. The measuring instrument generally has a single function of displaying the measurement result.

[0003]

Therefore, when it is necessary to record the measured values in the actual measurement, the measured values of the operator and the measuring instrument which bring the probe into contact with the object to be measured are read and recorded. A worker is needed.

Further, there is also a drawback that all the measuring procedure must be carried out manually, which requires man-hours. The present invention has been made in view of such problems, and an object thereof is to realize a measurement data collection device for a site suitable for labor saving of measurement.

[0005]

SUMMARY OF THE INVENTION An invention for solving such a problem is to provide a field measurement sensor block for converting a physical quantity of a measurement object into digital measurement data and outputting the digital measurement data, and a digital measurement output from the sensor block. And a processing block for storing data according to a preset program.

[0006]

The sensor block converts and outputs the physical quantity to be measured as digital measurement data, and the processing block stores and processes the digital measurement data according to a preset program.

Therefore, labor can be saved by preliminarily individually programming the processing procedure for each measurement application at various sites in a removable external memory such as a memory card.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 10 is a sensor block, 20 is a transmission block, and 30 is a processing block.

The sensor block 10 converts an analog electric signal corresponding to a measured physical quantity such as insulation resistance, temperature, pressure, etc. output from the amplifier 11 into a digital signal by the A / D converter 12 and outputs the digital signal. It should be noted that the A / D converter 12 may be provided with a display 13 if necessary.

The transmission block 20 is the sensor block 10.
This is not always necessary when the distance between the processing block 30 and the processing block 30 is short, but when data transmission is required, wired transmission by cable or wireless transmission by radio waves, optical signals, etc. is performed.

The processing block 30 has a CPU 31 as a core, an operation unit 32, a ROM 33, a detachable external memory 34 such as a memory card, a communication unit 35 for transmitting data to and from the outside, a display for displaying processing results and the like. It is composed of a container 36 and the like. Then, for example, the digital signal transmitted from the sensor block 10 is decoded, the result is processed by the external memory 34 according to a preset program, and the result requested by the key operation of the operation unit 32 by the operator is displayed on the display unit. 36. The measurement data and the processing contents thereof can be stored in the external memory 34, or can be transferred to an external personal computer or the like via the communication unit 35 to perform various data processing.

FIG. 2 is a timing chart related to the operation of FIG. In the figure, (A) is a trigger signal output from the processing block 30 to the sensor block 10 to capture measurement data. (B) is sensor block 1
Measurement data output from 0. Generally, the A / D converter 12 mounted on the sensor block 10 of this type has a one-chip configuration and continuously outputs converted data. Therefore, the data output request signal (trigger signal) output from the processing block 10 and the sensor block 1
It is not always synchronized with the measurement data output from 0. (C) is input data of the processing block 30.
(D) represents a data processing section in the processing block 30. (E) represents a memory execution section in the processing block 30. (F) represents the communication execution section in the processing block 30, and (G) represents the display execution section in the processing block 30.

When measuring in a noisy place, the noise resistance can be improved by coding and transmitting the measurement data. Further, a configuration in which the measurement result of the sensor block 10 is sent out periodically is also possible, which is an effective solution for surely obtaining correct measurement data in the current situation where there is a shortage of workers engaged in on-site measurement work.

Although the A / D converter 12 is described as being mounted in the sensor block 10 in the above description, it may be mounted in the processing block 30. In this case, the sensor block 10 outputs an analog signal. As a result, a user who already has the sensor block 10 (measuring device) having an analog output can utilize this.

[0015]

As described in detail above, according to the present invention, the following effects can be obtained. That is, the sensor block having a function as an on-site measuring instrument is equipped with a digital signal output function, and the processing block stores a program for executing data processing according to the measurement purpose in advance and outputs measurement data from the sensor block. Since an external memory that can store data is detachably installed, it is possible to realize an on-site measurement data collection device with excellent operability that is suitable for various on-site measurement applications, and is effective in saving labor in on-site measurement work.
