Abstract

This paper focuses on a micro-temperature controller which can be used in Antarctic telescope. This controller uses integrated digital temperature sensors and platinum sensors for temperature measurement, and uses single-chip for the system control, and single-bus for signal and data information transmission, which can meet different kinds of heating. With this controller we can solve the problems about temperature of the telescope, such as there are too many temperature test pots on the telescope, the complex control of mirror defroster, and the problem of wiring in such low temperature. In this paper there are only 4 cables needed to make the connection between center computer and power supply. And the remote control and monitoring can be achieved by the center computer. It is very space less, components and energy less, and after series of tests, it can meet the temperature control need of Antarctic telescope.
