The live aquatic long-distance logistics monitoring system
Abstract : With the continuous improvement of living standards, people's requirements about the quality of seafood aquatic are also increasing. Especially for fresh seafood products more and more demand for the product. But the way to the mainland to supply the city's seafood restaurant is a long distance. Therefore, it is a inevitable requirement to do a good job to make people to eat fresh seafood aquatic products. With the rapid development of computer measurement and control technology's wide application, Microcontroller as the core of the control system development and application of aquatic transport has greatly improved the level of control of environmental factors. This design paper presents a control system which regarded the STC89C52 microcontroller as the based control unit, the DS18B20 as the temperature sensor, the polarographic type LAMINATING oxygen electrode sensor as the oxygen sensor control system. The system is designed the hardware circuit and associated applications. The hardware circuit includes STC89C52 microcontroller, temperature measurement circuit, temperature acquisition module, dissolved oxygen acquisition module, the limit alarm module, heating module, cooling module, oxygen module, keys and display module and other modules. System program includes the main program, the read temperature / oxygen concentration subroutine to calculate the temperature / oxygen concentration in the subroutine, key processing program, LCD display program.
