AbstractThe POrtable Submillimeter Telescope (POST) was put into operation in November 1999. We briefly introduce the control system of the telescope, including both hardware and software. The hardware is based on the S-Bus of a SUN workstation. Industrial standard I/O interfaces are adopted to fulfil different purposes of information transfer. Pulse width modulation and harmonic driver are adopted to the antenna driving system, which is controlled in a mode of closed-loop positional feedback. The control software is to accomplish various observing and diagnostic functions of the telescope. The software is designed as a centralized real-time, multi-task package on the base of the UNIX platform. The present version of the entire control software includes 14000 lines of source code in C language. The control system as a whole realizes all functions of a highly automatic all-sky submm telescope used to observe cosmic submm line radiation, particularly the neutral atomic carbon line at 492 GHz. Besides, the system can be operated remotely. The principle as well as the software can be applied to control other precision radio telescopes
