DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement system for arranging sensors at several positions in a test space and analyzing the distribution of temperature and wind speed in the test space in the development of an air conditioner or a refrigerator. It is. More specifically, the method of registering the sensor position in the measurement system is devised.

[0002]

2. Description of the Related Art When analyzing the distribution of temperature and wind speed in a certain test space, a net or a column is set up in the test space, a sensor is attached to the net or the column, and a test formed by the net or the column is performed. The temperature and wind speed are measured for a cross section in the space (such a cross section is referred to as a measurement cross section). Then, measured values of temperature and wind speed are obtained for several measurement sections, and the distribution of temperature and wind speed in the test space is analyzed based on the measured values.

[0004] In such a measuring system, were registered in the location information memory 8 individually the position of each sensor 2 ₁ to 2 ₅ using the keyboard 5 or the like. For this reason, the position of the sensor has to be registered again even if the measurement cross section is slightly changed. At this time, if the number of sensors is large,
The registration process was very complicated, causing input errors. Further, when analyzing the distribution of the temperature and wind speed in the test space, the measurement cross section is frequently changed. For this reason, every time the measurement section is changed, the position of the sensor must be re-registered, and a large amount of time is spent for analysis.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG.
FIG. 1 is a configuration diagram showing one embodiment of the present invention. FIG. 1 and FIG.
The same reference numerals are given to the same components. In FIG. 1, 73
Is a grouping means, in the sensor 2 ₁ to 2 ₅ summarizes the sensor on the same plane or collinear to one group. For the sensors grouped in this way, the registration unit 71 registers the position of the group and the position of each sensor in the group in the position information memory 8. 74 is a changing means, when the measurement section is changed,
The position of the group registered in the position information memory 8 is changed. In this case, the position of each sensor in the group is not changed.

A description will be given of an example of a method of grouping in the measurement system configured as described above.

FIG. 2 is an explanatory diagram for grouping sensors arranged on the same straight line in the test space 1. In this example, three sensors S1, S2, S3 are arranged on a straight line L. In this case, the position information is registered in the position information memory 8 as the position of the group: the X and Y coordinates of the straight line L. The position of the sensor: the Z coordinate of the sensor. That is,
After (X ₀ , Y ₀ ) is registered as the position of the group, Z ₁ , Z ₂ , and Z ₃ are registered as the positions of the sensors. FIG. 3 is FIG.

Record. FIG. 5 shows the position information registered in the case of FIG.
FIG. Even if this position information is also displayed on the display unit 6,
Good.

In such a measurement system, when a column is set up in a test space and a sensor is attached to the column to perform measurement, grouping is performed as in the example shown in FIG. In this case, if you want to move the column and take data on another straight line, it is not necessary to re-register the position of each sensor on the column, only the X and Y coordinates that determine the position of the group are changed. do it. When a net is placed in the test space and a sensor is attached to the net for measurement, grouping is performed as in the example shown in FIG. In this case, if it is desired to move the net and obtain data on another plane, it is not necessary to re-register the position of each sensor on the net, and only the Z coordinate for determining the position of the group needs to be changed. Good.

FIG. 6 is an explanatory diagram showing another grouping method. In this grouping method, a group is provided with an attribute and a reference vector defining a position and a direction. The attribute indicates the type of the sensor belonging to the group, such as temperature and wind speed. The reference vector is determined by the starting point and the vector components in the X, Y, and Z directions. To perform grouping, first, an attribute and a reference vector are determined. Thereafter, a relative vector having the start point common to the reference vector and the end point of each sensor position is input. The starting point of the reference vector and each vector component may be arbitrarily determined. FIG.
In the example of the reference vector V, the coordinates of the starting point are (X ₀ ,
Y ₀ , Z ₀ ), and the vector components in the X, Y, Z directions are X ₁ −X ₀ , Y ₁ −Y ₀ , and Z ₁ −Z ₀ , respectively. The relative vectors V1, V2, and V3 have (X ₀ , Y ₀ , Z ₀ ) as a starting point and end points at the positions of the sensors S1, S2, and S3. FIG. 7 is a diagram showing registered information in the case of FIG. This position information may also be displayed on the display unit 6. In FIG. 7, l, m, and n are unit vectors in the X, Y, and Z directions. FIG. 7 shows, for example, that the reference vector V is given by V = (X ₁ −X ₀ ) l + (Y ₁ −Y ₀ ) m + (Z ₁ −Z ₀ ) n.

By grouping as described above, the position of each sensor is determined by the relative vector. Therefore, when the reference vector is moved, rotated, or both, each relative vector also moves and rotates. Thus, even if the reference vector is not only moved but also rotated, the relative position of the relative vector with respect to the reference vector does not change, so that it is not necessary to change the vector component of the relative vector. You only need to change the ingredients. In addition, since the groups are provided with attributes, different types of sensors can be handled in groups. Note that sensors having different attributes may be included in one group depending on the method of division.

[0015]

According to the present invention, sensors on the same plane or on the same straight line in the test space are collectively registered in one group. It is not necessary to change the positions of the individual sensors, just the coordinates of the group. This simplifies registration work when changing the measurement cross section,
Input errors can be reduced. In addition, it can quickly respond to changes in the measurement cross section that are frequently performed in the analysis of the test space,
The time required for analysis can be reduced.
