A control system of testing machine for rock breaking is developed based on Atmega 16 single-chip microcomputer, which acquires analog signals by a pressure sensor, a displacement sensor and a torque sensor. The system converts the signals into digital signals by means of A/D conversion and data processing, and displays them on the LCD screen. The parameters on the testing machine, such as pressures, displacements and torques, can be achieved in real time in the system. Then they are analyzed to obtain rock breaking characteristics. It is shown by experiment that the system meets the control requirements of the testing machine for rock breaking.

In order to achieve high-accuracy, high speed and low cost A/D conversion, a new design based on STC12C5A32S2 single-chip microcomputer (SCM) is given. Compared with the previous A/D conversion, the biggest advantage is that the paper combine software with hardware and it can adjust the speed of transformation through procedure.We don't need to modify circuit, just need to modify signals of input and procedures. So the flexibility of A/D conversion can be enhanced, also saved costs. The design mainly makes use of new function of STC12C5A32S2 SCM to realize conversion between analog signals and digital signals. In order that researchers can analyze and use the convention results, the design add a LCD display module. The paper primarily analyses the design of circuit and interface technology between the SCM and other chips. Also, the peculiar function of STC, the LCD display method of LMB202DDC and the flow of software are expounded in detail. The simulation result based on Proteus is given by the end of paper.

The garbage salvage ship is made from polystyrene plastic as hull framework and STC89C52 single-chip microcomputer to control the core, and consists of DC gear motor, photoelectric sensor, power circuit and other circuits. The system uses STC89C52 to control the boat to move forward, backward or turn through the I/O port. Tracing is finished by infrared obstacle avoidance sensor E18-D80NK. Working manner of the infrared obstacle avoidance sensor E18-D80NK was introduced and its application scheme based on STC89C52 single-chip microcomputer in the control system of garbage salvage ship was put forward.
