The total station instrument can be freely erected at any point on the ground. As long as the corners of two or more known points can be measured, the coordinates of the station can be obtained. This method is often used in large-scale digital maps and construction sampling.
The WGS-84 coordinate system is the coordinate system adopted by GPS, and the star calendar parameters released by GPS are based on this coordinate system. The whole of the WGS-84 coordinate systemCalled World Geodical System-84, it is a geodically fixed coordinate system. The WGS-84 coordinate system was established by the U.S. Department of Defense Drawing Bureau.
WGS84 coordinate system: that is, the World Geodetic System, an internationally common coordinate system. The longitude and latitude obtained by the GPS chip or Beidou chip included in the device is generally the WGS84 geographical coordinate system. At present, Google Maps adopts the WGS84 coordinate system (except for China).
The coordinate system of gps is the wgs-84 coordinate system. Definition The origin is the center of mass of the earth, and the Z axis of the spatial right-angled coordinate system is defined by BIH (1980)The Earth Pole (CTP) direction, that is, the origin of the international agreement CIO, is jointly recommended by IAU and IUGG.
Coordinate system commonly used in GPS measurement 1 WGS-84 coordinate system The coordinate system adopted by GPS is the WGS-84 geocentric coordinate system. It is a geocentric coordinate system with the center of mass (the center of mass) of the earth as the origin. The X and Y axes are in the equatorial plane of the earth. The Z axis coincides with the rotation axis of the earth.
1. It is mainly composed of four links: controller, controlled object, actuator and transmitter. Controller: The main circuit or control can be changed according to the predetermined order.The wiring of the circuit and the change of the resistance value in the circuit to control the start-up, speed regulation, braking and reverse master command devices of the motor.
2. Composition 1) Measuring instrument: any device used to obtain measurement results.
3. The basic components of general computer measurement systems include sensors, signal conditioners, computers and application software. Since the computer can only process digital signals, the A/D conversion device has become an indispensable link in the computer test system.
4. A complete detection system or detection device is composed of several parts such as sensor, measurement circuit and display recording device. Complete the functions of information acquisition, conversion, display and processing respectively. Of course, it also includes indispensable parts such as power supply and transmission channel.
Refers to the collection of operations, programs, measuring tools, equipment, software and operators used to assign values to the characteristics to be tested. The measurement system can include physical measuring tools and chemical reagents. The fixed measurement system is called measuring equipment, which is an indispensable part of engineering technology, scientific research and quality management.
De-measurement system: refers to a system composed of measuring personnel, being measured, measuring tools/jigs and other equipment, environment, operating procedures/operation methods or software; measurement system analysis: in order to analyze the variation presented in the results of various measurement and test equipment systems, statistical research must be carried out.
From a broad perspective, the measurement system should include measurement personnel and measurement environment and other contents.The components of the measurement system are interconnected and mutually constrained.
It refers to the measuring instrument that displays the value. Its display can be analog (continuous or discontinuous) or digital, it can display multiple values at the same time, and it can also provide records. Such as analog voltmeter, digital frequency meter, micrometer, etc.
Transmitter: The function is to detect process parameters and transmit the measured values in the form of specific signals for display and adjustment.
