Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] Such as figure 1 , In the interface isolation circuit, resistors R1 and R2 are current-limiting resistors, R3 and R4 are output pull-up resistors, capacitors C1 and C2 respectively form low-pass filters with R1 and R2 to filter out high-frequency noise, and diodes D1 and D2 prevent flooding current input. The conduction current of the optocoupler LED is IF, the conduction voltage drop is VF, the collector conduction current of the phototransistor is IC, and the conduction voltage is VCE. The interface circuit uses optocoupler HCPL-0631 for electromagnetic isolation.

[0024] Such as figure 2 , In the acquisition control card start acquisition command interface circuit, the start acquisition command pstart of the ground detection platform is connected to the K1-2 signal terminal of the long-line communication interface of the data recorder through the long-lin...

Description

Technical field [0001] The invention relates to a dynamic parameter measuring device, which is suitable for the field of memory. Background technique [0002] As a manifestation of a country's comprehensive national strength, national defense construction not only reflects its level of technological development and international status, but also in a strategic sense is a strong guarantee and solid backing for a country's politics, economy, culture, and diplomacy. Although we are now in an era of peaceful coexistence in international relations, looking at the situation at home and abroad, local wars, terrorist attacks, and separatist activities occur from time to time, international and social instability and contradictions are still prominent, and national defense construction still has a great role in historical development. strategic significance. [0003] With the development of modern technology, especially ultra-high-speed computer and communication technology, nationa...
