Abstract:

We design an automatic test instrument for solving the problem of quick test of the function modules of an meteorograph. It can obtain the detection result of its function modules by analyzing the acquired data from function modules and comparing them with transmitted standard signal. We also present its design idea and hardware and software design methods. Application results show that the instrument can quickly detect the function modules of a meteorograph. This significantly shorten the detection time, as compared with simple manual detection.

Key words: function module of a meteorograph, automatic test, fault diagnosis, CAN bus
