Abstract

PURPOSE:To enable the start from the next measuring procedure without vanishing memory content even at the time of the replacement of a battery, by using a memory element holding stored data as it is even when a power source is cut off and storing data in said memory element. CONSTITUTION:A computer has a memory element capable of holding memory content even when a power source is cut off and data is stored in said memory element at every measurement. Further, a battery is checked at each time when measuring procedure is finished and, when the indication of the replacement of the battery is issued, the present position of a program at that point of time is stored in the memory element and, therefore, even if the battery is detached for the purpose of replacing the battery, measured data is held and the position of the program finished is stored. Therefore, if a new battery is mounted thereafter and the program after the replacement of the battery is used, measurement can be started from new measuring procedure without again performing measurement from the beginning.

Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a method for renovating the outer wall of an existing building such as a building, and specifically, it relates to a method for renovating the outer wall of an existing building such as a building, and specifically, it relates to a method for renovating the outer wall of an existing building such as a building. This invention relates to a method for measuring the shape of the exterior wall of a building when installing exterior materials.

For building renovation work that does not involve removing the existing exterior materials mentioned above,
The external shape and dimensions of the building must be known accurately.6 Normally, the building's blueprints are available and can be used as a reference, but the building may be distorted or deformed during construction and may deviate from the blueprints. In addition, it is not possible to design new exterior materials only from blueprints because of post-construction remodeling, deformation, etc. Therefore, when remodeling, it is necessary to accurately measure the external dimensions of the building. It is necessary to understand not only the dimensions of the shape, but also the angle of each wall surface, the relationship between the building and the road and adjacent boundaries, and deformations such as collapse and twisting of the entire building.Since it is only 1 floor, it is necessary to understand the level relative to the horizontal plane, the vertical axis, etc. It is also necessary to measure the twist.

Previously, these measurements had to be carried out on a scale by setting up scaffolding or gondolas along the building to be renovated. Such work is dangerous and requires long hours of work by many workers. In addition, because the measurement had to be carried out with a plumb bob down, there was also the problem that the work could not be done on windy days. Furthermore, the error caused by thermal expansion of the scale becomes too large to be ignored.

Therefore, the present inventor invented a method of measuring using a transit (Japanese Patent Application No. 6O-163872), in which the angles to multiple measurement points determined according to the shape of the building's outer wall are measured at two locations far from the building. This method involves inputting the results into a computer and outputting the three-dimensional coordinate values of each point.

Some recent transits can convert measured values into electrical signals and output them digitally. If such a device is connected to a computer, three-dimensional coordinates can be immediately obtained by inputting measured values directly into the computer.

Therefore, it was possible to solve the problems that occur when measuring with conventional scales.

- is trying. To measure by connecting the Higashi-mentioned transit to a computer, it is necessary to take the measurements in a location far away from the building where the building can be seen, that is, in the open air, and enter the measured values, so you must use a computer that uses a battery as its power source. Of course, this is not a problem in itself; many portable microcomputers can also operate using batteries as a power source. However, the above measurement involves many measurement points, and in order to ensure accuracy, it is desirable to perform direct and reverse measurements by transit, so it takes a considerable amount of time, and one battery may not last until the end of the measurement. Furthermore, even if there are only a few measurement points and the measurement can be easily completed, the battery may run out during the measurement due to continuous use of the computer. In such a case, the battery must be replaced, but if you remove the battery carelessly, the data measured up to that point and the execution number of the program will be lost.
The present invention solves this problem, and makes it possible to prevent data loss even when the battery is replaced, and to immediately continue measuring from the next measurement procedure after the procedure that has already been completed. The aim is to provide a measurement method that can

[Structure of the Invention] Therefore, the present invention uses, as a computer, a computer having a memory element whose memory contents do not disappear even when the power is turned off, such as a magnetic bubble memory, a floppy disk, etc.
In addition to storing the measurement data in the memory element, a battery check is performed to detect the degree of battery consumption after each measurement procedure is completed, and if the battery check indicates that the battery should be replaced, the data is stored in the memory element. The feature is that the current position of the program is memorized.

The above measurement procedure does not mean the measurement of one point per se, but one continuous common measurement such as measuring all measurement points using either the forward or reverse measurement method using a transit. It means a process.

1. By using a memory element that retains stored data even when the power is turned off, as in the present invention, and storing data in this memory element, there is no risk that the memory contents will be lost even if the battery is removed. A computer powered by a battery is usually capable of checking the capacity of the battery.The present invention performs this battery check every time the above-mentioned one measurement procedure is completed. Even if an instruction to replace the battery is issued, the small diameter will still be operable for at least 30 minutes, so after one measurement procedure is completed, a putty chinch is performed, and the instruction to replace the battery is issued. Therefore, when you start the next measurement procedure, there is no risk that the battery will run out and the power will be cut off even if you continue to perform measurements until the next battery check is completed. . According to the present invention, when a battery check indicates that the battery should be replaced, the current position of the program that operates the computer is stored in the memory element, so when the battery is replaced and the computer starts operating again, the first step is to replace the battery. You can enter from the memorized current position rather than from the current location.

An example will be described below. First, a method for measuring dimensions of a building's outer wall shape using a transit will be described.

As shown in FIG. 1, transits 21 are installed at positions A and B away from a building 20. Although it is possible to measure by installing two transits at two locations at the same time, normally one is measured first and then the transit is moved to the other for measurement. It goes without saying that these positions A and B must be in a position where the building 20 can be seen, and the distance 111:c between these positions A and B is actually measured using a scale. If there is a difference in level between points A and B, the horizontal distance is corrected. In the case of a slight slope, the difference is almost negligible and can be ignored. The points to be measured are the overall outer edge as shown by P on the building 20, the corners around the windows, the edges of each uneven part, and the points necessary for designing exterior materials such as new curtain oars that will be installed later. Set it anywhere. These points may be marked in advance, but the transit operator may draw a diagram of the entire building and the details of each point installation location, and then point the points on that diagram.)
It is practical to write it down along with .

Now, a method of measuring the coordinates of Pi among the many points P mentioned above will be explained. It goes without saying that the other points are exactly the same.If we align point Pi with the cross of the telescope of transit 21 at point A (standardize it), we will find the horizontal angle Ai (angle A of triangle ABC) from point A to point Pi. )
and vertical angle α can be measured, and similarly from point B to point Pi
The horizontal angle Bi and the vertical angle β are measured according to the following criteria. From these angles Ai, Bi and the above C, from point A to point P
Distance to i and distance a from point B to point Pi
is calculated, and from these the transit 21 placed at point A is
A three-dimensional coordinate plane position (Z, X) with the origin at the position is determined. It goes without saying that the height Y is calculated from the angle α and the distance rab according to the sine law.

In this way, the three-dimensional coordinate values of point Pi with transshift 21 of point A as the origin are determined. The computer 22 connected to the transit 21 is programmed to read the angle data set by the 7M111 and automatically perform the above calculations by simply pressing a switch based on the transit 21.

By performing the same procedure for other points, the coordinate values of all points are determined. Regarding the height Y, the data at point A and the data at point B have different values. A due to slope etc.
This is because there is no guarantee that point and point B are on the same horizontal plane. However, if the values are converted to values from the reference level 23 as will be described later, the differences between the upper and lower measurement points are canceled out and become the same. However, since measurement errors occur, they will never be completely the same, but since they are just measurement errors, there is no problem in using either one.

It is difficult to use the coordinate values from the position of the transit 21 as described above when designing exterior materials, so we assume a reference level 23 at an arbitrary position on the building 20 and set a point 24 above it. The coordinates are converted into three-dimensional coordinate values set as the origin and output from the computer 22. This reference level 23 and reference point 24 select the most convenient location for designing the new cladding.

The computer 22 of this embodiment naturally uses a battery as a power source, and at the same time has a memory element such as a magnetic bubble memory that retains memory even after the power is turned off. As shown in FIG. 2, the programs that operate the computer 22 of this embodiment are: 1) a forward/reverse measurement program, 2) a measurement program for pressure measurement only, 2) a battery replacement program, and 2) a rough coordinate value from the reference point 24. Contains a calculation program to convert.

The following will explain the measurement order according to the above program. Note that "normal measurement" means measuring the transit 21 as it is, and "reverse measurement" means measuring by rotating the telescope horizontally by 180 degrees and then vertically by 180 degrees.

First, the measurement method of the above-mentioned direct/reverse measurement will be explained according to the flowchart of FIG. 3. A construction name is input, and the measurement data of N points P at the first measurement position A are input together with the point H1o, and the data are stored in the memory element. After this measurement procedure is completed, check the battery, and if there is no abnormality with the battery, proceed to the next measurement procedure for data input. If the battery is exhausted and needs to be replaced, turn it in the NO direction shown in the diagram. Go to and memorize the current position of the program.

If there is no need to replace the battery, then inverse data is input. In this case, each point is measured and each time it is input to the computer 22, it is compared with the previously memorized positive data of the same point. , Display the difference between the two.0 If the difference between the two is within the normal range, do the same thing at the next point, and have all points measure and input in the same way. If the difference is large at a certain point, the data at that point must be changed. To do this, after having the user input the point (number) for each point that needs to be changed, the user is required to input the measured positive data and negative data again, compare and display them, and then judge again whether the measurement is correct or not. do. If correct, proceed to the measurement at the second measurement position B, finish for the whole point,
After the measurement procedure is completed, if an instruction is given to perform a battery check again or to replace the battery, the current position of the program is stored in the storage element in the same way as described above.

In the above explanation, when inputting reverse data, compare the data of the normal reverse after measuring each point, display the difference, judge whether it is correct or not, and input the reverse data for all points while writing down the displayed difference. , I look at the difference data that I have written down and look for points that need to be remeasured, but it is also possible to display all the difference data after inputting it. In that case, it is desirable to perform the battery check after inputting the counter data.

Furthermore, in this embodiment, the difference between the normal and opposite data is simply displayed and the operator is responsible for making a judgment, but it is also possible to set the normal difference range in advance and have the operator input the opposite data. Each time a difference from the correct data is calculated, the difference may be compared with a normal difference range, and if it exceeds the range, that fact may be displayed.

The purpose of performing the direct and opposite measurements in this way is to prevent measurement errors.

The above is the first operation, that is, the operation at the first measurement point A in Figure 1. If there are no abnormalities in the battery check, then move the transit 21 to the second measurement point B and perform the operation completely. Data is input into the computer 22 using the same procedure. After inputting points A and B, the distance c between points A and B is inputted, and the point number of the reference point 24, which is the origin of the coordinates, is inputted, and coordinate axis conversion is calculated. These calculations will be described later.

Similarly, a battery check is performed after each measurement procedure is completed.

If you do not need to take measurement errors into consideration, you may only perform correct measurements as shown in Figure 4. In this case, A
The measurements at point and point B are each one measurement procedure, and the measurement data is input and stored, and the battery is checked after each measurement procedure, and if there is an instruction to replace it, the current position of the program is memorized. let

When the battery check indicates that the battery should be replaced as described above, the current position of the program is memorized. Therefore, even if the battery is removed, the data up to that point is stored, and the position where the measurement of the program was interrupted is also stored, and these data are not lost even when the power is turned off. When you start the start program after battery replacement shown in ■, the current position is called in,
Once it is determined whether the measurement is in the opposite direction or not, if the measurement is in the opposite direction, ■,■
, ■, The current positions of [phase] are confirmed, and the operation is started from each position shown in FIG. If only correct measurements are to be made, check either ■ or ■ and restart from the respective positions shown in FIG. The reason why it is determined whether or not it is normal/reverse measurement is that, as described above, this embodiment is capable of performing only normal measurement in addition to normal/reverse measurement. In any case, by executing the above program, it is possible to start from a new measurement procedure without returning to the beginning.

Next, a program for calculations such as coordinate axis conversion (FIG. 6) will be explained. In this calculation, it is first determined whether or not to change the previously input reference point, and if there is no need to change it, the data is called in and the calculation is executed. After that, it is determined whether or not it is necessary to print the coordinate values, and if so, it is executed and printed out. The reason for determining whether or not the reference point is changed is that there are cases where it is desired to set the reference point at two or more locations. If this is not necessary, you can simply perform the calculation. Also, the reason for determining the necessity of printing the coordinate values is that when the coordinate values have already been printed, it is desirable to omit printing them when other calculations such as the distance # between each point are performed separately. It is.

If the coordinate values of each point above are calculated and stored, various calculations can be made as needed, such as calculating the distance between each point and calculating the variation in the average value, based on it. Since it has no direct relation to the present invention, its explanation will be omitted.

In this example, measurements are taken at two points, point A and point B, but if there is a point that cannot be seen from the two points, measurements may be taken at other measurement positions as necessary. Needless to say.

[Effects of the Invention] As described in detail above, in the present invention, the computer has a memory element that can retain memory contents even when the power is turned off, and the memory content is stored in the memory element for each measurement, and The battery is checked every time a procedure is completed, and when a battery replacement instruction is issued, the current position of the program at that point is stored in the memory element, so even if the batch reel is removed to replace the battery, the measurement data can still be retained. and remembers the location of the program when it has finished. Therefore, if you then insert a new battery and use the program after replacing the battery, you can start a new measurement procedure without having to start over from the beginning.
