Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.
[0043] This application provides a raw coal bunker material level measurement method and system and a computer-readable storage medium. The detection terminal equipment receives the measurement instructions sent by the host computer installed in the control room or other convenient places for operation, and according to the control instructions. The warehouse material level is detected, and the detection results are fed back to the host computer. The operator decides whether to send further adjustment instructions to the detection terminal equipment according to the feedback results receive...

The invention discloses a raw coal bunker material level measurement method and system, the system comprises detection terminal equipment, an upper computer and a cloud server, the detection terminalequipment receives a control instruction sent by the upper computer, and the control instruction comprises an automatic purging instruction, a coal bunker modeling instruction, and / or a coal bunker raw coal storage amount and coal pile shape measurement instruction; the detection terminal equipment executes detection according to the control instruction and feeds back a detection result to the upper computer; the control instruction is further adjusted to the detection terminal equipment according to the detection result received by the upper computer and fed back by the detection terminal equipment; the upper computer uploads the received detection result to the cloud server for sharing; according to the raw coal bunker material level measurement method and system, three-dimensional viewdisplay and real-time monitoring can be carried out on the shape of the coal pile in the raw coal bunker, the measurement precision is high, the automatic purging function is achieved, and more automation is achieved.
Description
technical field [0001] The invention relates to the technical field of material level detection, in particular to a method and system for measuring the material level of a raw coal bunker. Background technique [0002] The raw coal bunker is the main facility for the temporary storage of raw coal in large coal mines, power plants and coal washing plants. In most cases, it is a vertical cylinder made of concrete. The material level of the coal bunker is an important process parameter that needs to be controlled in time during the production process. . [0003] The feed port of the raw coal bunker is usually at the upper end, while the discharge port is at the lower end. If only feeding but not feeding, a cone will be formed at the upper end of the material. If only feeding but not feeding, a cone will be formed at the upper end of the material. Form a conical funnel body, this phenomenon is called material repose angle in powder engineering theory. The size of the angle of ...
