Abstract: This paper introduces an automatic control system scheme for concrete block batching using the 89C52 microcontroller as the control core, analyzes its measurement circuit, and provides a detailed program flow. Keywords: Concrete batching control 1. Introduction The non-fired block forming machine uses coarse sand, crushed stone, fine sand, stone powder, and cement, mixed in a certain proportion, and presses the raw materials together through a hydraulic system to form standard bricks, hollow bricks, and paving bricks used in construction. These bricks do not require firing, thus protecting arable land and the environment, and are a new type of environmentally friendly building material strongly supported and promoted by the state. The proportion of concrete block raw materials is a crucial factor in ensuring its quality. Therefore, a microcomputer concrete block batching system was developed. It can automatically complete the metering and batching of sand, crushed stone, and cement according to different concrete block proportions, making it an ideal device for ensuring concrete block quality, improving efficiency, and reducing labor intensity. This project was listed as a key science and technology project of the 2005 Henan Province 15th Five-Year Plan (0524250032) and received funding support. 2. Working Process of the Batching Machine The structural diagram of the concrete block batching machine is shown in Figure 1. Depending on the actual situation, 2 to 4 hoppers can be selected. Raw materials such as sand, stone, and cement are stored in different hoppers. First, the first type of raw material is conveyed to the weighing hopper via a conveyor belt for weighing. When the weight of this raw material reaches its set value, the conveyor motor stops. After a delay, the second type of raw material is conveyed to the weighing hopper via its conveyor belt for weighing. When the weight of this raw material reaches its set value, the conveyor motor stops. This cycle continues until all raw materials have been weighed. Finally, the conveyor motor of the weighing hopper starts, transporting the batched raw materials to the lifting mechanism, which then sends them to the mixing plant.
