The instrument communicates with the machine through an interface, and the data display is saved after the measurement data in the single chip is received, and the user is allowed to design the hole depth through the keyboard input, and the inclination value is designed to facilitate the judgment and the unqualified. The measurement results can be formed into various production reports according to actual needs, so as to fully utilize the functions of the machine and make management a new level. The communication program with the MCU is written in the language, and the program such as data display save and print is written in the language. The key technology of the software lies in the echo judgment analysis program. After the edge conversion is finished, the program takes the echo wave according to a noise threshold, and the position amplitude signals of each echo above the threshold are all stored in the memory of the single chip microcomputer, and the amplitude is made. After the correction processing, the echoes whose amplitudes are ranked in the first five digits are taken out for analysis, and the true hole bottom echo is found to calculate the depth value and sent for display, and the plugging hole indication is displayed for the plugging echo. The detailed analysis process will not be detailed here. The deep hole depth dipometer in mining uses sonic pulse as a measuring method. The deep hole in mining can be equivalent to the principle of an acoustic waveguide. The hole depth is calculated by measuring the time difference between the transmitted wave and the reflected echo at the bottom of the hole. The meter uses a single-chip microcomputer to sample and store the echo wave system and process the data. The processing software is an expert system based on the analysis and statistics of the echo wave characteristics of various complex conditions. It has intelligent features, which makes the instrument's correct rate of complex deep-hole echo analysis of working conditions greatly improved. Industrial tests show that the comprehensive depth measurement of the hole depth of the instrument (including various complex geological conditions) exceeds 90 measurement depths, and the inclination measurement accuracy can reach a dual purpose. These characteristics and sounding indicators make the instrument a leading domestic product. In order to adapt to the very harsh environment of the underground, when designing the instrument, we strive to make it small in size and light in weight, with its own battery power supply, and focus on solving the requirements of waterproof, moistureproof, antimagnetic and shockproof. The instrument has become a simple, light, and reliable practical instrument for the measurement of deep holes in mines. In this example, there are layers of coal with different ash, which are sequentially loaded into a short position. Then vent at a certain flow rate. This layer of coal can represent different coal seams or different types of coal, and a vertical line on the graph can be used to derive the composition of the coal. After the start of coal charging, the composition of the discharged coal is roughly the number of coal and coal. If the FIFO method is used, the operator will see the entire coal flow in the period of time. (Finish) A mesh net bag for fruits and onions is a type of reusable bag made from a lightweight, breathable mesh material that allows air to circulate around the produce inside. These bags are typically used to store and transport fruits, vegetables, and other small items, such as nuts and seeds.
