Abstract
This thesis lesson is to aims at how the medium-sized food-house’ temperature to be supervised and controlled, in order to reduce the food lose. At densely populated present condition in our country, this design even has the realistic meaning. Due to local electronics manufacturing technique level in our country and the economy developing level, however, a large quantity adoption of supervising and control system are needed in our country. This design chooses to use the spare parts of the best price ratio for single a machine, and adopts INTEL’8031 chip to make system construction simplified, also the benefit received in the place of upper system; The upper system outputs every point’ temperature of the food in the house, make it easy to control the food’ temperature by time ,decreased the manpower, material resources, financial power. By the error margin analysis, this system meets the national related request completely.calendar clock, give a alarm when it exceeds limit, the function that signs in, convenient for controlling grain’s temperature. to lesson human force，financial and material resources.through error difference, this system is suitable for our country’s standard.
key word: temperature, the function that signs in, give a alarm, calendar clock
