The tradition temperature detecting takes critesister as temperature sensor , critesister cost is low , need the follow-up signal treatment circuit but, the critesister reliability is relatively relatively poor and , accurate degree measuring the temperature is low , systematic accuracy of detecting is bad. We select and use Intel for this purpose 8088 work give first place to the controller, realizes the temperature checking up round , have and the sensor malfunction give an alarm waiting for a function. That it is different from the tradition critesister temperature detecting , it is able to a playback directly quilt measuring the temperature and may demand to realize digital value numerical reading way by simple programming according to reality, makes system structure tend towards the simplicity , reliability more highly as a result. Be systems turn to design that the ability is strong , expansion goes to the lavatory simple , anti-interference , have applying a prospect very broadly in temperature detecting. And the temperature the main body of a book is introduced detailedly makes rounds of visit to the population design frame inspecting up system, system fun
