The collection and measurement of weak signal is the key part of the design. This paper designed a multi-channel weak signal collecting and measurement system based on single chip microcomputer. Microcomputer of 8051 single chip was used as the core of the system. In this paper, the working principle of the measuring system was introduced, the hardware circuit and software program was designed. The test showed： this system can be used to collect and process all kinds of weak signals in real time.This system will be used in conjunction with different kinds of sensors.
