The common bus on bus control is RS232. With the development of field bus technology
field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000
a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage
which should have abroad application prospect for data record experiment. 2010 IEEE.

High speed photograph measuring instrument is mainly used to measure and track the exterior ballistics
which can measure the flying position of the missile in the initial phase and trajectory. A new high speed photograph measuring instrument is presented in this paper. High speed photography measuring system records the parameters of object real-time
and then acquires the flying position and trajectory data of the missile in the initial phase. The detection distance of high speed photography is more than 4.5km
and the least detection distance is 450m
under the condition of well-balanced angular velocity and angular acceleration
program pilot track error less than 5. This instrument also can measure and record the flying trail and trajectory parameters of plane
aero naval missile.
