The above work is intended to set up an automatic logic synthesis system to translate a register transfer level language descriptions into hardware logic diagrams.

The technical process and control object of the automatic ultrasonic inspection of LSAW, the logic diagram of technical process, hardware interface system and software program of PLC were introduced.

The spatial information system consists of 8 logical map layer series, 16 types of map layers, more than one hundred types of map units. Based on these data, 5 achievement maps have been compiled.
