Description

The present invention relates to a data recorder having a function of recording and verifying observation data from a surveying instrument such as a total station or electronic theodolite used for surveying work. .

[Conventional technology]

As a conventional data recorder, there is one that has application software installed and is compatible with converse observation.However, if the allowable range is memorized and the calculation result of the observed data is out of the allowable range, it will be displayed to re-measure. ing.

[Problems to be solved by the invention]

When recording observation data in a data recorder using an electronic total station or an electronic theodolite during counter-observation in a surveying operation, it is possible to judge whether the observed data is correct or requires observation again. It has become indispensable for workers to be able to do things under observation conditions.

In the past, it was difficult to replace this function with a data recorder, although the field calculator was used to perform self-verification by hand calculation, so the conventional data recorder displayed only the presence / absence of remeasurement.

That is, the allowable range includes observation difference, double angle difference, altitude constant difference, difference in distance measurement set, and difference between distance measurement sets.If the result of observation exceeds one of these limits, remeasurement is required. There is. However, the part to be re-measured in the horizontal survey, for example, in the case of 2-pair observation, it is 0 ° scale wheel
There was no way to know if the 90 ° scale was wrong, so all observations had to be repeated.

If this can be automatically judged in the data recorder,
For the observer, the work proceeds smoothly and the observation time can be shortened.

[Means for solving problems]

The present invention is characterized in that a determination function is provided in the data recorder to solve the above problems.

This judgment function consists of the observed difference for each pair (meaning the difference between the positive observation value and the anti-observation value within the observation data at the same point) and the double angle (meaning the sum of the positive observation value and the anti-observation value). It is considered as a judgment element, and as a result, it is used to judge the magnitude of the observation difference (which means the difference in the difference in the contra-observation) and the double angle difference (which means the difference in the double angle in the converse observation).

However, there is insufficient processing capacity to solve all the data online in the data recorder using these elements.

In order to efficiently and probabilistically make the above judgment within this limited processing capacity, it is preferable to use the judgment of the size of the difference as a result of detailed investigation of the nature of the observation data that has been remeasured. Focusing on this, and taking into account the recent improvements in the accuracy and reliability of observation equipment, we were able to make highly accurate judgments.

[Action]

By using the data recorder according to the present invention, when a remeasurement becomes necessary, the operator can think of the part by displaying the part that must be remeasured and bringing it to the input waiting state. Without the need for judgment
You can work quickly. At the same time, when it comes to re-measurement, the worker always wants to know which part was wrong, and that is also necessary. You can also satisfy this.

(Embodiment) FIG. 1 is a block diagram of the first embodiment of the present invention, second is an external view of the first embodiment of the present invention and a view showing a state of connection with various surveying instruments, and FIG. It is a figure which shows the flowchart of the microcomputer 6 in FIG.

In FIG. 1, which is an electrical block diagram of the data recorder, the CPU 1 reads a numerical value indicating a permissible range and the like from the operation keys 2 and each command, and performs a predetermined operation. CPU
A surveying instrument 20 that outputs distance measurement values and angle measurement values as electric signals as shown in FIG.
Or a lightwave distance measuring device 21 that outputs a distance measurement value as an electric signal
Or, the distance measurement value can be output as an electric signal, and the angle measurement value can be optically read. The surveying instrument 22 is connected, the electronic theodolite 23 that outputs the angle measurement value as an electric signal, and the external battery 24 are connected. . The data recorder 7 shown in FIG. 2 is an RS-2 for communicating with an external computer.
It has a 32C interface connector 8.

The CPU 1 sequentially stores the distance measurement values and the angle measurement values input via the interface 3 in the storage means 4, and performs arithmetic processing according to the command from the operation keys 2. The result of the arithmetic processing is displayed on the display means 5 such as a liquid crystal display.

It should be noted that the CPU 1 and the storage means 4 form a microcomputer 6.

Next, in order to simplify the explanation, the handling of the observation difference, which is one of the quality judgments of the horizontal angle observation, will be described with reference to the flowchart of FIG.

The microcomputer 6 firstly allows the observation difference, which is the difference between the operation keys 2 and the difference between the same points for each pair (the difference between the positive observation value and the anti-observation value in the observation data at the same point). Is input (step 30), subsequently the observation data is sequentially read and stored (step 31). Then, the difference and the observed difference are sequentially calculated by the observed data stored in the storage means (step 32). Then, it is tested whether or not each obtained observation difference is outside the allowable range introduced in step 30 (step 33), and if all the observed differences are within the allowable range,
In horizontal angle observation, re-measurement is not necessary, the surveying is terminated, and a message to that effect is displayed (step 34). If some of the observed differences are outside the allowable range, the maximum value among the differences of the observation points that caused the observed difference outside the allowable range is searched (step 35), and the obtained maximum is obtained. It is searched for which measuring point of which wheel number of the turn corresponds to the difference and the result is displayed on the display means 5 (step 36). As a result, the worker will re-measure the displayed counter rotation number, but even the survey points that seem to have large surveying errors will be displayed, so be especially careful when surveying at those survey points. You can

The re-measurement data of the counter rotation number displayed on the display means is replaced with the observation data of the same rotation number previously surveyed and stored (step 37), and when the re-measurement ends (step 37).
38) Then, step 33 is entered again, and steps 35, 36, 37 and 38 are repeated until all the observed differences are within the allowable range.

The flow chart of FIG. 3 explained above exemplifies the case of observing two or more times at the time of horizontal angle survey. However, if the observation is carried out only once, there is one difference at the same measurement point. Since we can only obtain it, we cannot obtain the observed difference. Therefore, in this case, the allowable range of the difference may be instructed from the operation key 2, and the measurement point having the difference outside the allowable range may be displayed.

In addition, there are two types of allowable range: in the case of horizontal angle observation, there is an observation difference and a double angle difference, but the double angle difference is a double angle (of the observation data at the same point, the sum of positive and anti-observation values in seconds). ), The processing after the determination is similar to the observation difference, so that the above description is sufficient for the horizontal angle observation. On the other hand, the altitude angle has a difference in altitude constant, but this is because it is possible to know whether the observation data is directly within the allowable range, so complicated verification work such as horizontal angle observation is not necessary, and the distance The difference within the measurement set and the difference between the distance measurement sets are related to the distance measurement. Since these are also used to directly judge whether the observation data is within the allowable range, it is possible to directly know which observation data should be remeasured. In this case, too, no complicated verification work such as horizontal angle observation is required.

That is, for example, taking the distance as an example, the difference is obtained for a plurality of distance measurements, compared with the allowable range, and if the observation exceeds the allowable range, the observation position and the operator should be re-observed. It may be notified by a buzzer, display flashing, or the like. Thereby, the operator can observe the displayed observation position again and input correct data.

〔The invention's effect〕

As described above, according to the data recorder of the present invention,
For example, in horizontal angle observation (of course, all observations are performed at the total station at the same time), it is possible to display which station number of which wheel number in the contra-turn requires re-measurement, so that surveying work can be performed efficiently. it can.
