Description

  The present invention relates to a remote control device (hereinafter referred to as a remote control device) for remotely controlling a surveying instrument.

  Conventionally, in order to measure the position of a measuring point, a reflecting target is installed at the measuring point, and an operator collimates the reflecting target with a telescope of a surveying instrument such as a total station (electronic rangefinder), then the telescope The distance measurement light is emitted along the optical axis (collimation axis) and the distance measurement light reflected by the reflective target is received to measure the distance. At this time, the telescope uses the encoder provided in the total station. The azimuth angle and altitude angle of the reflective target collimated in (2) are measured, and the position at the designated coordinates is calculated from these measured values.

  In recent years, surveying instruments equipped with an automatic collimation device have been developed in order to reduce the labor for collimating the reflective target and to reduce collimation errors caused by the habit of workers. The automatic collimation device emits collimated light (infrared laser) along the optical axis (collimation axis) of the telescope and receives the collimated light reflected by the reflective target, thereby determining the position of the reflective target. It detects and makes the optical axis of a telescope correspond with a reflective target (refer the following patent documents 1, 2, 3, etc.).

  In recent years, a remote control device has been provided separately from the surveying instrument main body so that the surveying instrument can be remotely operated even from a location away from the surveying instrument main body. Such a remote control device has a light emitting portion provided on the front surface thereof, and emits remote control signal light (infrared rays) carrying a command signal from the light emitting portion. The main body of the surveying instrument receives remote control signal light, detects a command signal, and operates according to the command signal.

In order to measure the position of a survey point with a surveying instrument equipped with such a remote control device, conventionally two workers, one (mirrorman) standing on the survey point with the reflective target and the remote control device, Fixed on the survey point and another person operates the surveying instrument and collimates the reflective target, then the mirrorman performs the measurement with the remote control device, or the other person operates the surveying instrument directly and performs the measurement. It was.

  However, in the conventional measurement by the surveying instrument and the remote control device, since the reflection target must be installed at the measuring point, the reflection target must always be carried in addition to the remote control device, which is inconvenient.

  In order to solve such inconvenience, an object of the present invention is to provide a remote control device that can easily measure the position of a measuring point without carrying a reflective target.

  In order to solve the above-mentioned problems, in the invention according to claim 1, an operation key for operating a surveying instrument equipped with an automatic collimation device and an operation key for data input are arranged on the upper surface, and the surveying instrument is arranged on the front surface. In a remote control device of a surveying instrument provided with a light emitting unit for emitting a remote control signal light carrying a command signal to be sent, the remote control device also includes a reflection target for reflecting collimated light emitted from the surveying instrument on the front surface. The magnetic sensor for obtaining the azimuth angle data relating to the direction of the remote control device is provided inside, and the azimuth angle data is also carried on the remote control signal light.

The invention according to claim 1 is characterized in that a scale for reading an offset value from a measurement point is provided on a side surface and a back surface of the remote control device.

The invention according to claim 2 is characterized in that, in the invention according to claim 1, the magnetic sensor also obtains altitude angle data relating to the orientation of the remote control device, and the altitude angle data is also placed on the remote control signal light. .

  As is clear from the above description, according to the invention according to claim 1, since the reflection target is also provided on the front surface of the remote control device, the collimation light or the ranging light emitted from the surveying instrument is reliably reflected to the surveying instrument. It is possible to use the remote control device as a reflective target, which is convenient because it is not necessary to carry a conventional reflective target. In addition, when the azimuth data regarding the orientation of the remote control device measured by the magnetic sensor is placed on the remote control signal light and sent to the surveying instrument, even if the specific part abutting on the remote control device measurement point is separated from the reflection target It is possible to calculate the position of the measuring point at the coordinates obtained.

According to the first aspect of the present invention, since the scale for reading the offset value from the measurement point is provided on the side surface and the back surface of the remote control device, the offset value from the measurement point of the reflection target can be measured. The position of the station can be measured with reference to.

According to the second aspect of the present invention, since the magnetic sensor also obtains altitude angle data related to the direction of the remote control device, and the altitude angle data is also placed on the remote control signal light, the specific portion to be brought into contact with the measurement point of the remote control device; When the reflective target is away, the position of the station at the specified coordinates can be calculated more accurately.

  Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the remote control device of this embodiment. FIG. 2 is a diagram for explaining a method of measuring the position of a measuring point using the remote control device of the present embodiment.

  As shown in FIG. 1, the remote control device 1 of this embodiment is provided with operation keys 2 for inputting commands and data on the upper surface 12, and a light emitting unit 3 for emitting infrared remote control signal light on the front surface 14. The reflective target 5 is provided beside the light emitting unit 3. The light emitting unit 3 is arranged in a recess 4 provided on the front surface 14 of the remote control device 1 so that the tip does not protrude outside from the recess 4 so as not to be damaged by colliding with other things. Of course, visible light remote control signal light can be used instead of infrared remote control signal light. Further, azimuth angle data and altitude angle data relating to the orientation of the remote control device 1 can be obtained from the three-axis components of the geomagnetism in the coordinate system provided with the magnetic sensor 17 on the printed circuit board (not shown) and fixed to the remote control device 1. I am doing so. As the magnetic sensor 17, a sensor using a light and small Hall element is desirable.

  The reflection target 5 is made of a reflection prism or a reflection sheet, and reflects the reflected light in the direction in which the incident light comes even if the incident light does not enter perpendicularly. The collimated light emitted from the surveying instrument 8 22 or the distance measuring light 24 is reliably reflected to the surveying instrument 8.

  Further, the front face 14 of the remote control device 1 is provided with a collimation mark 7 indicating the center of the reflection target 5 around the reflection target 5. When the reflection target 5 is collimated on the surveying instrument 8 side, the surveying instrument The crosshairs indicating the optical axes of the eight telescopes 9 are easily aligned with the center of the reflection target 5. Furthermore, in order to measure the offset values r and s from the measurement point P of the reflection target 5, scales (scales) 6 in units of mm are attached to both side surfaces 16 and the back surface 19 of the remote control device 1.

  By the way, the arrangement of the light emitting unit 3 and the reflective target 5 is not required to place the light emitting unit 3 in the center of the front surface 14 and the reflective target 5 beside the light emitting unit 3 as shown in FIG. As long as it is provided in the front surface 14, you may arrange | position both.

  Based on FIG. 2, a method for measuring the position of a measurement point P to be measured, such as a corner portion of the wall surface 10, by a single worker using the remote control device 1 of the present invention will be described. For this purpose, a surveying instrument 8 equipped with an automatic collimation device and a magnetic sensor 18 is used. The magnetic sensor 18 is preferably a Hall element, similar to the one provided in the remote control device 1, and is provided on a printed board (not shown). Based on the geomagnetism detected by the hall element 18, the surveying instrument 8 calculates and stores the azimuth angle and altitude angle of the telescope 9.

  First, the surveying instrument 8 is placed at the reference point Q, and the telescope 9 of the surveying instrument 8 is pointed at the surveying point P. Next, it walks to the measurement point P, and presses the remote control device 1 against the wall 10 or the like with the front surface 14 of the remote control device 1 facing the surveying instrument 8, so that a predetermined specific part of the remote control device 1 ( For example, the end or the like is fixed to the measuring point P. Then, since the light emitting unit 3 and the reflection target 5 are provided on the front surface in the remote control device 1, both the light emitting unit 3 and the reflection target 5 can be directed to the surveying instrument 8. When a predetermined specific portion cannot be fixed to the measurement point P, the offset values r and s from the measurement point P of the reflection target 5 are read from the scale 6 attached to the side surface 16 of the remote control device 1, and this offset value r , S are input using the operation key 2 and are sent to the surveying instrument 8 from the remote control device 1 on the remote control signal light 20, and the azimuth angle data and altitude angle data detected by the magnetic sensor (Hall element) 17 are remote control signals. Send it on the light 20.

  Then, a command to turn on the automatic collimation device is sent from the remote control device 1 to the surveying instrument 8 on the remote control signal light 20. Then, in the surveying instrument 8, the automatic collimation device works to emit collimation light 22 along the optical axis (collimation axis) of the telescope 9 and receive collimation light 22 reflected by the reflection target 5. Thus, the position of the reflective target 5 is detected and the target is always automatically collimated. Here, the remote control device 1 sends a measurement start command on the remote control signal light 20 to the surveying instrument 8.

  Of course, if the front surface 14 of the remote control device 1 is substantially directed to the surveying instrument 8, even if the telescope 9 of the surveying instrument 8 is not directed to the survey point P, quick automatic collimation is possible. The surveying instrument 8 can calculate the azimuth angle and altitude angle that the remote control device 1 faces from the azimuth angle data and altitude angle data sent from the remote control device 1. The surveying instrument 8 can quickly point the telescope 9 toward the remote control device 1 by adjusting the azimuth angle and altitude angle of the telescope 9 to the azimuth angle and altitude angle that the remote control device 1 is facing. Thus, the surveying instrument 8 can immediately start automatic collimation without searching for the light emitting unit 3 of the remote control device 1 for a long time.

  Upon receiving the measurement start command, the surveying instrument 8 emits distance measuring light 24 having a wavelength different from that of the collimating light 22 along the optical axis of the telescope 9 as soon as the reflecting target 5 is collimated accurately. By receiving the distance measuring light 24 reflected by the target 5, the distance to the reflective target 5 is measured, and the horizontal angle and altitude angle of the reflective target 5 are measured from the angle of the telescope 9 at this time. Then, from these measured values, the azimuth angle data and altitude angle data relating to the orientation of the remote control device 1 detected by the offset values r and s and the magnetic sensor 17 for the position at the designated coordinates of the measuring point P are taken into consideration. To calculate.

  Furthermore, when it is desired to measure the position of another survey point, the reflector 5 is slowly moved to another survey point while the reflection target 5 is directed toward the surveying instrument 8. Then, since the automatic collimation device of the surveying instrument 8 works and the telescope 9 tracks the reflection target 5 and keeps collimating at all times, the remote control device 1 is fixed to another survey point, and the remote control device 1 starts the surveying instrument. When a measurement start command is sent to 8, the position can be measured immediately.

  As described above, when the surveying instrument 8 including the remote control device 1 and the automatic collimation device of the present embodiment is used, the remote control device 1 can be used even as a reflective target, and one person can work without carrying the conventional reflective target. Even an employee can measure the position of many stations. At this time, even if the specific portion to be brought into contact with the measurement point P of the remote control device 1 and the reflection target 5 are separated, the position of the measurement point P at the designated coordinates can be accurately calculated.

  By the way, the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the magnetic sensors 17 and 18 obtain the azimuth angle data and the altitude angle data, but the magnetic sensors 17 and 18 may obtain only the azimuth angle data. Normally, when the remote control device 1 is used as a target, the remote control device 1 is used in a substantially horizontal manner, and there is almost no measurement of a very large altitude angle. The same effect as that of the above embodiment is achieved.

It is a perspective view of the remote control device according to an embodiment of the present invention. It is a figure explaining the method to measure the position of a measuring point with the said remote control apparatus.
