Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping, and particularly relates to a GNSS static receiver base control device and system. Background Technique

[0002] The full name of GNSS is Global Navigation Satellite System, which is a satellite system for autonomous geospatial positioning covering the globe. It is used for navigation and positioning measurement, and can transmit real-time position and time information by using satellite signals, so as to calculate geographical location information such as longitude and latitude of ground receiving devices.

[0003] GNSS static control measurement is to use several GNSS receivers to track GNSS satellite signals. For the observed carrier phase observation values, the difference method is used to obtain the baseline vectors (i.e., coordinate differences) between each observation station. Then, the coordinates of other observation points are calculated based on the known baseline vectors and coordinates.

[0004] In the existing measurement device during GNSS static measurement, it is necessary to keep multiple instruments powered on and stationary simultaneously to obtain accurate measurement data. Once the instrument moves, the collected data will no longer be continuous and consistent, and it is necessary to immediately stop the observation and reposition the instrument for rework. There are problems such as the need for manual measurement and recording of the instrument height, and the inability to remotely monitor the status of the static receiver. Content of the Utility Model

[0005] The purpose of the utility model is to provide a GNSS static receiver base control device and system that facilitate data measurement and recording and remotely monitor the position of the static receiver.

[0006] The utility model is implemented as follows:

[0007] A GNSS static receiver base control device and system includes a connecting plate for connecting with a tripod. The connecting plate is connected with a mounting seat through a centering adjustment mechanism. A laser emitter, a displacement sensor, and a connecting seat for mounting a static receiver are arranged on the mounting seat. The laser emitter is electrically connected with a laser ranging module, the laser ranging module is electrically connected with a storage module and a display module, and the displacement sensor is electrically connected with a displacement alarm module.

[0008] Further, the centering adjustment mechanism includes a plurality of screw feet rotatably connected with the connecting plate. The screw feet are threadedly connected with the mounting seat. An eyepiece and an objective lens for centering, and a spirit level for leveling are arranged on the mounting seat.

[0009] Further, the laser ranging module includes a receiver electrically connected to the laser emitter. The receiver is electrically connected to a signal adjustment circuit for amplifying, filtering, and shaping the signal transmitted by the receiver. The signal adjustment circuit is electrically connected to a microprocessor for analyzing and calculating the signal shaped by the signal adjustment circuit. The microprocessor is electrically connected to the storage module and the display module respectively.

[0010] Further, the displacement alarm module includes a signal processing circuit electrically connected to the displacement sensor for amplifying and filtering the displacement signal. The signal processing circuit is electrically connected to a comparison circuit for judgment. The comparison circuit is electrically connected to an acoustic-optic alarm circuit and a wireless transmission circuit.

[0011] Further, the laser emitter is electrically connected to a mobile power supply module. The mobile power supply module is electrically connected to the laser ranging module, the storage module, the display module, and the displacement alarm module respectively.

[0012] Further, a connection port is provided on the connecting plate. An internal thread for threaded connection with a tripod is provided in the connection port. External threads for threaded connection with a static receiver are provided on the connecting seats.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In practical applications, a tripod is placed on a preset control point. The tripod is connected to the device through the connecting plate, and the static receiver is connected to the device through the connecting seat. The mounting seat is centered and leveled through the centering adjustment mechanism. After the instrument is set up, it is powered on and run. The laser pulse beam emitted by the laser emitter hits the surface of the control point and feeds back a signal to the laser ranging module for calculation and processing. The laser ranging module transmits the processed data to the storage module and the display module respectively. The storage module stores the measurement data, and the display module is used to display the measurement results for easy viewing. When the operator is not near the instrument and the instrument moves, the displacement sensor feeds back the signal of the displacement change detected by the instrument to the displacement alarm module. The alarm module processes and judges the signal fed back by the displacement sensor and issues an alarm to prompt the staff that the base has moved. The present utility model facilitates data measurement and recording and remotely monitors the position of the static receiver. Description of the Drawings
