Abstract
Introduced the machinery Run automatic control system the composition, the design proposal, the principle of work, the mechanical lubrication system design, the debugging and the service maintenance, regarding the enhancement lubrication precision, lengthen the mechanical lubrication automatic control service life and so on all to have the extremely vital role, in the mechanical lubrication systems control the lubricating oil to the mechanical lubrication vital role. Based on the lubricating oil in machinery unceasing reduction to the machinery the harm, uses the PMC system to carry on the control, lets the mechanical part obtain the good lubrication, and also acts according to the mechanism the working mode active status, the automatic control for the oil, the cycle time, by saves the lubricating oil. The system take the heat sensitive sensor and 80C51 as a core, includes signal gathering, D/ specificallyA switch, signal processing, A/D switch, LED monitor. In the design with the hot sensitive sensor gathering signal, transmits and accepts the data using the MCS-51 monolithic integrated circuit serial interface. The hardware design application electron design automation tool, the software design uses the modular programming method, this controller has the volume slightly, the sensitivity high, the precision high characteristic, moreover the manufacture craft simple, the price is inexpensive, has the strong usability
The integrated temperature sensor, the automatic control device, the 80C51 chip, PMC are systematic, auto-alarm
