Environmental Monitoring and Control of Semiconductor Production Workshop Based on 51 Single Chip Microcomputer
Abstract：With the development of technology, semiconductor chip production has gradually entered a stage of large-scale, automated, intelligent, and for a semiconductor workshop, safety issues are extremely important, the key to safety issues is the monitoring and control of temperature and dust concentration. This paper first analyzes the research background and significance of environmental monitoring in semiconductor production workshops, discusses its current situation and development prospects at home and abroad, and designs a semiconductor production workshop environment monitoring and control based on 51 single chip microcomputer.
. The design takes 51 single-chip microcomputer as the core, DS18B20, DHT22, GP2Y1014AU0F as the sensor, reads the data through single-bus communication and serial port communication between the single-chip computer and the sensor, and analyzes the data. Finally, the user-friendly interface is used to control the environmental parameters in real time. Below the threshold and display the result. This design uses Altium Designer software for hardware circuit design, Keil software for software program design, device selection, wire bonding, hardware circuit debugging, software debugging download, and finally achieve all expected functions, and the system has simple operation and measurement accuracy. The advantages of small error, complete functions, etc. have certain application value.
