Description
Technical field
The present invention relates to satellite positioning monitoring technical fields, can be led using global satellite more specifically to one kind
Boat system makes multiple monitoring point for displacement share a monitoring host, and can be according to the frequency of setting in the monitoring aerial connected
Between the multi-antenna set GNSS signal interchanger that automatically switches.
Background technology
As the global position systems such as GPS, GLONASS, the Big Dipper are wide with other numerous areas in mapping, navigation, communication
General application and popularization, technology development is gradually ripe, and also achieves preferable development in satellite positioning monitoring field, especially in ground
It is widely applied in terms of engineering monitoring.
In existing satellite level monitoring system, positioning antenna and the monitoring one-to-one connection of host, each monitoring point
There are independent hardware, power supply, communication, construction.Its principle is, independent displacement monitoring station is installed in each monitoring point, using with
Differential signal between base station carries out monitoring point the positioning of degree of precision, then location data is uploaded network, to right
The relative displacement situation of monitoring point carries out long-term automatic monitoring.
Though there is some technologies to propose some displacement monitoring technical solutions, generally existing for geotechnical engineering monitoring at present
Problems with and deficiency：All it is one-to-one connection between every monitoring aerial of conventional monitoring methods and monitoring host, it is each to monitor
Point is required for independent hardware, power supply, communication, construction, monitoring cost excessively high, and the later stage needs to carry out individually each monitoring station
It safeguards, the heavy workload of later maintenance and of high cost, stabilization of equipment performance is also difficult to be protected.
Invention content
The technical problem to be solved by the present invention is to：A kind of multi-antenna set GNSS signal interchanger is provided, multiple days are equipped with
Line interface and antenna change-over switch make multiple monitoring point for displacement share a monitoring host, and can be according to the frequency of setting
Automatically switch between the monitoring aerial connected.
Technical solution of the invention is：The present invention provides a kind of multi-antenna set GNSS signal interchanger, including more
A antennal interface, dual serial port and power interface；The antennal interface is used for wired by antenna cable with positioning antenna
Connection, the power interface and serial port are connected to monitoring host；
Further include microcontroller and antenna change-over switch, the microcontroller controls the antenna change-over switch and is switched to required connect
The monitoring aerial connect.
Further, the quantity of the antennal interface is 10.
The multi-antenna set GNSS signal interchanger for implementing the present invention, has the advantages that：By the way that multiple days are arranged
Line interface and antenna change-over switch make multiple monitoring point for displacement share a monitoring host, and can be according to the frequency of setting
Automatically switch between the monitoring aerial connected, and the monitoring location data of different antennae is transferred to monitoring host, realizes one
Displacement monitoring of a monitoring host to multiple monitoring points.This interchanger is used in the system for monitoring displacement of monitoring point comparatively dense,
Monitoring and later stage O＆M cost can be substantially reduced, multiple monitoring points only need a set of hardware device that effective monitoring, phase can be realized
Cost input to hardware, power supply, communication, construction can be increased for traditional monitoring equipment, improve the stability of monitoring device.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing：
