Embodiment Construction

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0034] Aiming at the deficiencies of existing testing devices, a data compression algorithm for time series signals is proposed, and a time series signal storage test device is designed based on this algorithm. Due to the data compression algorithm, the device uses ferroelectric memory as the storage medium to meet the storage capacity requirements. The ferroelectric memory has the characteristics of high-speed reading and writing, ultra-low power consumption and unlimited writing, and will not produce The block can effectively improve the reliability of the storage test device and reduce the power consumption of the device.

[0035] Such as figure 1 As shown, the present invention discloses a time series signal st...

Description

technical field [0001] The invention belongs to the technical field of embedded storage testing and data compression, and specifically discloses a time series signal storage testing device and method based on data compression technology. Background technique [0002] During the process from launch to target impact, the missile control system usually needs to send out a series of actuation signals to realize relevant actions, such as: engine ignition signal, explosion bolt detonation signal, timing control signal, counter cycle signal, etc. In order to check whether the missile-borne control system gives the corresponding signal at the specified time point, the missile-borne time series signal storage test device is usually used to record the level characteristics of these time-activated signals. The data can be used as the basis for evaluating whether the load control is working properly. [0003] The existing missile-borne time series signal storage test device usually sam...
