With the gradual improvement of living standard, people's safety awareness is also on the increase. Widely used in the era of electronic products. The traditional temperature control system to the current development of electronic intelligent temperature control system. It is to some extent improved the precision of temperature control, reduced the intensity of the work of field staff to improve work efficiency. In addition electronic smart temperature control system can also be formed with the computer communication system. Great convenience to the field staff on the management of the system is described in detail in this paper the development of our equipment throughout the process. Hardware and software we have discussed in detail, and describes the difficulties encountered in the design, and analyze and solve problems. Due to experimental conditions and equipment limitations, the system can only achieve a single point temperature control. But when the system software upgrade, you can achieve a smooth multi-point temperature monitoring.
Microcontroller to the success of the current used in the smart meter, electrical and mechanical equipment, process control, data processing, automatic detection and household appliances and other aspects.
MCS-51 series microcontrollers particularly suitable for real-time control, intelligent instruments, the main structure of the multi-machine systems from other fields, is the ideal application areas controlled 8-bit machine.
This paper presents an integrated temperature sensor AD590 and 8031 as the core temperature monitoring system design. Warehouse Temperature Control System 8031 chosen as the host of cheap, because no program memory chip, so the core of its foreign expansion as 8K bytes of program memory EPROM-2764, used as an address latch 74LS373. 8-bit A / D converter 0809,8279 support 8-bit LED digital display, keyboard input, and TPUP-16 mini-printer to achieve human-machine communication.
Proved that the system can realize multi-point temperature within a grain depot intelligent control, and low cost, multi-function and high reliability.
