Problems solved by technology

If the object to be measured is two points that are far apart, it needs to be aligned by visual inspection, which is difficult to operate; if the object to be measured or its surroundings have parts or objects that block GNSS signals, this kind of measuring instrument cannot be used accurately. If the object to be measured is a material with an electromagnetic field such as metal or is easily affected by an electromagnetic field and can reflect or scatter GNSS positioning signals, the GNSS signal will be interfered and cannot give accurate required results, resulting in measurement failure; Accurate measurement cannot be performed even if there are other strong electromagnetic interference around the measured object
The above-mentioned situations all make it difficult for the existing GNSS measuring instrument to play a role, which brings many problems and inconvenience

Embodiment 1

[0055] see figure 1 , Embodiment 1 of the present invention provides an electronic direction finding integrated system, including a direction finding device (direction finding unit), a laser beam emitting device (laser beam emitting unit), a Bluetooth transmission module (Bluetooth transmission unit), and a mobile communication terminal. Wherein: the two ends of the direction finding device are GNSS antennas, which can receive GPS, GLONASS, Galileo, Beidou and other global navigation satellite system positioning and navigation signals; then analyze the GNSS system positioning and navigation signals received by the antennas at both ends, and calculate the dual antenna of the device The line pointing to the phase center is used as the precise angle between the measured object and the local true north direction; the laser beam emitting device is installed on the longitudinal centerline of the direction finding equipment, and the emitted visible laser beam is parallel to the phase ...

Embodiment 2

[0057] see figure 2 , embodiment 2 of the present invention provides an electronic direction finding integrated system, and figure 1 The difference is that there are two laser beam emitting devices, and the two laser beams emitted by the two laser beam emitting devices are located on the same straight line. figure 2 shown by the two arrows. figure 2 The embodiment of the invention conveniently locates the direction-finding device in the middle of the object to be measured, so that one laser beam is aimed at one end of the object to be measured, and the other laser beam is aimed at the other end of the object to be measured, and the operation is performed when there is a certain distance from the object to be measured It will be very convenient to get up.

[0058] The specific working process of the electronic direction finding integrated system of the present invention is as follows:

[0059] Make preparations at the experimental location, place the electronic direction ...

Abstract

The invention discloses an electronic direction finding integrated system and method. The electronic direction finding integrated system comprises GNSS system positioning signal-based double-receptionantenna direction finding equipment, a laser beam emission device, a Bluetooth communication and transmission module and a mobile communication terminal for receiving direction finding data; GNSS satellite reception antennas are arranged at two ends of the direction finding equipment; the GNSS satellite reception antenna at one end is a primary antenna and the GNSS satellite reception antenna atthe other end is a secondary antenna; and the laser beam emission device is mounted on the direction finding equipment. According to the system and the method, the measurement space range of the existing GNSS direction finding equipment is expanded so that the interferences caused by the tested objects to the GNSS signals are avoided; and the problem that the existing direction finding equipment needs to mount screen displays is simplified, and the problem that that measurement errors are caused as the persons observe the screen display at a close range to interfere the GNSS signals is avoided.

Description

technical field [0001] The invention relates to the technical field of electronic direction finding integration, in particular to an electronic direction finding integration system and method. Background technique [0002] After investigation, it is found that the current high-precision pointing measurement equipment on the market mainly uses dual GNSS (Global Navigation Satellite System, global satellite navigation system) antennas to receive the positioning signal of the global satellite navigation system (GNSS), and perform differential processing to obtain the direction of the measured object and the local true position. The technology of the included angle in the north direction realizes high-precision azimuth and pointing measurement. GNSS includes GPS, GLONASS, Galileo, Beidou and other global navigation satellite systems. [0003] This kind of GNSS pointing measurement device needs to be close to the object to be measured, so that the pointing of the measuring devic...
