Names given by the measurer to make it easier to identify the measuring point (for example, HOUSE, BE', IDGE, etc.)
In some cases, it may be necessary to add and record the survey data.

The data collector is a device for recording survey data, and the keyboard of the data collector is equipped with numeric keys from "O to 9", 26-character alphabet keys, and other operation keys. You can now enter the station name using -. However, the keyboard installed on a surveying instrument is designed to be the minimum size necessary for the operability of the surveying instrument so as not to interfere with the surveying operation of the surveying instrument, and the number of operation keys on the keyboard is also limited. Other than the number keys, a predetermined minimum number is required, and keys for inputting characters such as alphabets and kana are not provided.

Therefore, if you want to record survey data measured by a surveying instrument along with predetermined character data such as a survey point name, you can only record it in a data collector.

is converted into the corresponding characters rA-JJ and stored in the RAM, and is output to the display control section 107, and this character data is displayed on the lower section 6C of the display section 6.

The internal circuit of the memory card 8 inserted into the card insertion section 7 of the surveying instrument main body 1 is shown in the block diagram of FIG. That is, inside the memory card 8, there is a power transmission unit 84 that receives power supply, and a backup power supply (
(not shown), a signal transmitting/receiving section 82 that transmits and receives signals, and a memory section 82 that processes signals from the signal transmitting/receiving section 82.
It is composed of a signal processing unit 86 and a data converting unit 87 that enable reading and writing to the data. Then, by inserting the memory card 8 from the card insertion lower a (see Figure 1), the signal transmitting/receiving section 112 on the surveying instrument body side faces the signal transmitting/receiving section 82 on the memory card side. It becomes possible to transmit/receive data and transmit power.

Next, the $rim flow of the CPU unit 110 built into the surveying instrument main body 1 will be explained with reference to FIGS. 7 and 8.

After installing the surveying instrument at a predetermined installation point, the power switch of the basic surveying body 1 is turned on to enter the standby mode shown in step 700. Here, press the REC key 1, which is one of the function keys.
Press 8 to go to step 710. In step 710, it is determined whether or not the memory card has been properly inserted. If it is, the process moves to step 720, and the survey menu selection mode is entered. On the other hand, if the memory card is not inserted properly in step 710, for example, if the memory card is not inserted to the predetermined insertion position, or if the memory card is not inserted, the display section 6 will show "NO CARD". " is displayed. In step 720, a menu to be recorded is selected from among various measurement menus. Then, after standardizing the reflecting prism set up at the measuring point, ENT
By pressing the key 16, the process moves to step 730.

In step 730, a determination is made as to whether or not a measurement point number is to be input. Therefore, when inputting a measurement point number, in step 740, after pressing the numeric key 14 (14° to 149), the ENT key 16 is pressed to input a predetermined number. The input number (measurement point number) is displayed on the display section 6.

When the input of the point number is completed, the process moves to step 750.
It is determined whether or not to input a measurement point name.

When inputting a station name, in step 760, use the two-character selection keys 15 (15a, 15b) to change the number key 14 to [A-J), "K-T" in the conversion table 21.
, rU~&'' or ``0~9'' while shifting to any one of the four code groups, press the designated numeric key and enter an arbitrary station name consisting of letters, symbols, etc. do.

That is, when the CPU section 110 enters step 760, it determines whether or not key human power is present according to the processing flow shown in FIG.

First, if there is key power in step 800, it is determined in step 810 whether or not the key power is the character selection key 15, and if it is the 1 character selection key 15, step 820 is performed.
In this step, it is determined whether or not the character selection key 15a is pressed. If the character selection key 15a is selected, the code corresponding to the input digits "0 to 9" in the conversion table 21 is incremented by one in step 830 (see arrow 22 in FIG. 5); When the selection key is 1 or 5b, the conversion table 21 is selected in step 840.
The code corresponding to the input digits "0 to 9" is decremented by one (see arrow 23 in FIG. 5). And again step 80
Return to 0 key waiting for human power.

That is, by pressing the character selection key 15a, the number keys 14° to 14. The code corresponding to (a) rO~
9J −+ (b) rA ~JJ → (c) "K~T"
−+ (d) rU ~&J −+ (a) ro ~ 9J
→ (b) "A~J" →... can be shifted,
On the other hand, by pressing the character selection key 15b, the code is changed to (a) ro~9'' → (d) rU~&'' → (c) rK=T
”-+ (b) “A~J” −(a) “0~9” → (d
) can be shifted in the opposite direction, such as rU-&J. In this way, arbitrary characters and symbols can be input using the character selection keys 15 (15a, 15b) and the number keys 14 (14, -14,).

If the key is pressed again in step 800, it is determined in step 810 whether or not the character selection key 15 is pressed, and if it is not the one character selection key 15, it is determined in step 850 whether or not the end key (ENT key) 16 is pressed. Then, in step 850, the end key (ENT key) 16
If it is determined, exit this processing routine and proceed to step 77.
0 (see Figure 7).

On the other hand, in step 850, the end key (ENT key) is pressed.
If it is determined that the key is not 16, it is determined in step 860 which key among the number keys 14 (14° to 14.) has been pressed. Then, in step 870, the numerical input is converted into characters by comparing it with the conversion table 21 in the ROM.

Thereby, character data can be obtained from numerical input by pressing down the numeric key 14 (14, - 14.).

This character data is stored in the RAM and sent to the 1-display control section 107. Then, the process returns to step 800 to wait for key human power.

The processing routine described above describes the operation of converting numerical input into character input in the CPU section 110, but the actual operation is performed as shown in FIG.

That is, first in step 900, a character code is selected. This is done by pressing the character selection key 15. Then, in step 910, the number key 14 is pressed.
Press. Then, the CPU section 110 performs processing according to the processing routine shown in FIG.
The input characters are displayed (step 920). here,
If the character displayed on the 1 display section 6 is incorrect in step 930, the selected character is deleted by pressing the CA key 17 in step 940.

Return to the original step 900. Further, if the input characters displayed in step 930 are correct, step 9
The process moves to step 50, where it is determined whether or not to input any more information, and if further input is desired, the process returns to the original step 900.
The process returns to , and the same processing as described above is performed. On the other hand, if the input is to be ended in step 950, the routine is ended by pressing the end key (ENT key) 16.

Next, the explanation returns to the flowchart shown in FIG. When a predetermined measurement point name is input in step 760,
The process moves to step 770. In step 770, it is determined whether or not to input the reference height (prism height). If input, in step 780, the reference height is input using the Wt number key 14. Then, by pressing the ENT key 16, the survey is automatically performed in step 790, and the survey data is displayed on the display section 6 together with the survey point number, and is automatically recorded on the memory card 8.

When the recording of the survey data on the memory card 8 is completed, the process returns to the menu selection mode in step 720, and the same process is performed again.

Further, if the parameters in the machine are preset to "no measurement point name" or if no measurement point name is input, steps 750 to 760 are omitted and the process moves to step 770.

Furthermore, if the parameters in the machine are preset to "no change in reference height" or if the reference height is not manually adjusted, the reference height input step 780 can be omitted and step 7
Move to 90.

In the above embodiment, the Wl amount data is stored on the memory card 8.
The control flow of the CPU unit 110 when recording to a data collector is the same except that the recording location is a data collector connected to the CPU unit 110 via an external output connector. , and its explanation will be omitted.

When recording survey data on the data collector, the measurement point name is entered using the number keys 14 (14° to 14s) on the main body of the surveying instrument, so the data collector does not need keys for inputting characters. Therefore, the number of operation keys on the data collector side can be reduced accordingly. Therefore, there are advantages such as increasing the size of the display section formed on the data collector and increasing the degree of freedom in the layout between the keyboard section and the display section6.Furthermore, the CPU section on the data collector side can also be configured to the extent that it does not require a character input function. It is possible to simplify the data collector itself and to make it more compact, making it more convenient to carry.

Further, in the above embodiment, in the conversion table 21, input numbers "O to 9" are replaced with four codes (a) to (d) (numbers "0 to 9", letters and symbols "A to Z, &, etc."). ), but the correspondence between input numbers and letters is not limited to this, for example, the 51 sounds (a, i, tsu,
..., n) may be made to correspond, in the conversion table 21, 1, for example (a) rQ~9''
.

(e) “A~O, force~koJ,” (f) “Su~so, ri~to”
, (g) "Su-no, ha-ho", (h) "Ma-mo, ya-yo J, (i) r-ro, w-wo", (j) "N-, -
It can be made to correspond by using the seven codes "&Other symbols".

〔Effect of the invention〕

As is clear from the above explanation, according to the surveying instrument of claim (1),! Since the number keys have the function of closing text, it is now possible to input (record) text data such as arbitrary measurement point names to a memory card, which was not possible in the past.

In addition, characters can be entered without mechanically increasing the number of keys on the keyboard of the surveying device, so the area occupied by the keyboard on the surveying device remains the same as before, and the area of the keyboard has been expanded to facilitate surveying work. There are no obstructions or other problems; in other words, the appearance of the main body of the surveying instrument remains the same as before, but the functionality has been improved.

In addition, when recording survey data on the data collector, character data such as station names can be entered into the data collector without any key operations on the data collector, so the function of the memory calculation section on the data collector can be improved. The structure of the data collector can be made simpler than the conventional one by downsizing and reducing the number of operation keys, and as a result, the cost of the data collector can be reduced.
