The standard coal temperature controller mainly deals with the heating, temperature controlling time, automatic measuring and controlling instrument in the course of physical property test of coal. In order to make the temperature controller to preset the starting time and test items and samples in the constant temperature period of short-term power failure, not to scrap the sample and design. The technical proposal for solving the problem is arranged in the box body (1) on the liquid crystal display panel (2), keyboard (6) docking box (7), single chip microcontroller (7) chip and real-time clock (8) and AD converter (9) docking and auxiliary circuit CPU control circuit board (10). The switching power supply circuit board (11) is connected to the power output, 5V power, CPU control circuit for each device and solid state relay (12) with electric drive circuit, one way through the P3.4 microcontroller on the control of the liquid crystal display circuit. The solid state relay (12) is mounted on the power line of the resistance furnace. The utility model is mainly suitable for the laboratory to test the physical property of the coal, and can also be used for baking or heat treatment experiments of other materials.
