AUTO ALIGNMENT CONTROL METHOD FOR CARBON-IN-ASH MEASUREMENT SYSTEM USING MICROWAVE

摘要

This invention, by using a micro-wave advance to measure the advance tansobun flowing into the boiler duct in real time tansobun optimizing the micro-wave for the transmitting and receiving sensitivity and signal-to-noise ratio by applying the mutual alignment techniques to transmit and receive antenna of the measuring device to remove the root cause of measurement error, and can increase the accuracy of the measurement, the beam width is narrow band high frequency microwaves Sort tansobun advance to be able to take advantage of a measuring instrument to use it in anger could seek to improve performance and extensive use of the advantages as well as the frequency of the measuring device, with automatic alignment of the antenna is easy to install and maintain, a micro-wave relates to an automatic alignment control method of transmitting and receiving antenna of the unburned carbon with the measuring device, ; in place to secure the two antennas the first antenna while rotating the antenna in a second yaw axis from the opening surface of the first antenna the method is to find the largest reception sensitivity point at the nearest place, and for moving the antenna yaw (yaw) to the point where only the largest reception sensitivity by using movement of the second antenna step, while rotating the second antenna to the pitch axis of claim thee In the opening phase of the first antenna and the reception sensitivity to find the largest point at the nearest place, and the step of moving the antenna reception sensitivity, using only the pitch motion of the second antenna find a large pitch angle, the antenna of the two 2, a first antenna placed to secure the antenna yaw (yaw) is scanned, and the pitch (pitch) in the scanning angle and the reception sensitivity find the largest step of moving the antenna in the first position, the above process two antennas You can save the alternately performed, but by measuring the peak signal strength at each respective scanning comprises the step of alignment compared to the next scan is performed until the difference reaches the noise level.
