The method of design and realization of shock recorder based on the accelerometer is introduced. Double CPU is applied in the new system, it can develop the capability of data processing. By mounting the shock recorder on the goods, it can collect and calculate the real-time data to monitor and record all shocks that is exposed to the goods during its transportation.
