Problems solved by technology
Since only part of the electromagnetic energy reflected by the target object can be received by the radar, when using radar for height measurement, high transmission power is required and power consumption is large. At the same time, the radar height measurement method using electromagnetic wave reflection has low precision , generally around 10m

The invention provides a system and method for measuring the height. The system for measuring the height comprises a target object and a controller connected with the target object in a communication manner, the target object comprises a first signal emitter and a second signal emitter located below the first signal emitter, and the controller comprises a signal receiver. During measurement of the height, emission signals of the first signal emitter and the second signal emitter are received through the signal receiver, the distance between the first signal emitter and the signal receiver and the distance between the second signal emitter and the signal receiver are respectively calculated according to the time from the emission of the signals by the first signal emitter and the second signal emitter to the reception of the signals by the signal receiver, and the height of the fist signal emitter away from a horizontal plane in which the controller is located is calculated with the combination of the distance between the first signal emitter and the second signal emitter measured in advance. According to the system and method, the measurement of the height is accomplished, the signal power is low, and the measuring precision is high.
Description
technical field [0001] The invention relates to the technical field of measuring devices, in particular to a system and a method for measuring height. Background technique [0002] In reality, measuring the height of an object is the most basic measurement activity. Many tall objects cannot be measured with conventional contact measurement tools, especially in the fields of forestry, geology, mining, electric power, communications, roads and bridges, water conservancy, construction engineering and large-scale engineering installations. A non-contact method of measuring altitude. [0003] Using radar to measure height is a commonly used method of non-contact height measurement. Its working principle is: the radar transmitter installed on the ground generates enough electromagnetic energy and transmits it to the antenna through the transceiver switch, and the antenna radiates the electromagnetic energy to the atmosphere. The center concentrates on a very narrow direction to ...
