Title Cental cooling water temperature control system
Abstract
Along with highly speedy development with computer control technology, more and more advanced technology, equipments and methods for measurement is applied in modern automation control realm. This work of this monograph adapts to the development tendency, applying the single chip microcomputer to cooling water temperature. Control system of chip main engine. Now, more and more scientific research organization attach importance to cooling water temperature is very important to diesel engine. If cooling water temperature can keep in the first-rank range cooling water temperature, diesel engine’s power can be improved, and engine work more calmly.Central cooling water temperature control system based on 89c51 single chip microcomputer, in order to make cooling water temperature is fall dawn by putting cool water tank. System is divided into two parts: one is hardware circuit, the other is software chat and key control program. The principle and method of measurement temperature circuit, A/D circuit, keyboard and show circuit are discussed. Operation of system is simply, we can change the temperature range by using the 6 keys on control, and the temperature displayed on the control.Applying the single chip microcomputer to cooling water temperature automation control., it become the one of question for discussion in ship engine automation, this system provides a necessary condition for more study on diesel engine.
