Digital strong motion seismograph and multipath data acquisition interface thereof

Abstract

The invention discloses a digital strong motion seismograph and a multipath data acquisition interface thereof. The multipath data acquisition interface comprises a data acquisition and control unit, a data conversion unit and a synchronous serial unit, wherein the data acquisition and control unit is used for receiving a command of a microcontroller to set the working mode of an analog-to-digital converter and reset or synchronize the analog-to-digital converter; the data conversion unit is used for converting parallel data output by a signal latching analog-to-digital converter according to the state of the analog-to-digital converter; and the synchronous serial unit is used of converting the parallel data into serial data for outputting to the microcontroller. In the invention, multipath data acquisition of the digital strong motion seismograph is realized by using a complex programmable logic device (CPLD), so that the problems of occupation of a large quantity of general input/output interfaces, reduction in the processing efficiency of the microcontroller, increase in design and realization difficulties and the like caused by the general input/output interface of the microcontroller can be solved.

AI Technical Summary

Benefits of technology

This patented technology allows multiple channels of data from an electronic musical instrument to be collected simultaneously on different devices like computers or smartphones through a specialized circuit called CPDL that has programming capabilities. By connecting these circuits together correctly at once, it becomes possible to collect more than four types of data quickly while also reducing the amount of hardware needed compared to traditional methods such as USB interfaces.

Problems solved by technology

This patents describes different ways how an electronic equipment (EI), like a high performance liquid crystal display monitor (HLDM)) operational system works properly by transmitting and controlling its various components through specialized ports on one chip. However, there may exist many other types of connections needed due to factors like power supply voltage fluctuations caused by changes in temperature during operation. These issues make it difficult to achieve efficient transferring of data across these connection points without increasing their size and requiring complex designs.
