Wireless data collector based on DSP

Abstract

The invention discloses a wireless data collector based on DSP. The wireless data collector comprises a signal collecting module, a DSP microprocessor, a wireless transmission module, a data memory, a button, an LCD display screen, and an SD card base; the data terminal of the signal collecting module is connected to the data terminal of the data memory; the signal output terminal of the DSP microprocessor is connected to the signal input terminal of the LCD display screen and the signal input terminal of the wireless transmission module; the signal output terminal of the button is connected to the signal input terminal of the DSP microprocessor, and the data terminal of the DSP microprocessor is connected to the data terminal of the data memory and the data terminal of the SD card base. Through integrating a DSP microprocessor into a data collector, the data processing performance and vibration and impact resistant performance of the data collector are improved, and the data collector has the characteristics of small volume, low cost, and portability; furthermore, the data collector is provided with a wireless transmission module, and thus on-site data collecting and wireless data transmission in a short distance are achieved.

Description

technical field [0001] The invention relates to a data collector, in particular to a DSP-based wireless data collector. Background technique [0002] A conventional data acquisition system consists of a dedicated collector (card) and a host computer. The host computer manages the data acquisition process. After the collector completes the signal acquisition, it transmits the data to the host computer through PCI bus or standard serial port, etc., and the host computer processes the data and finally applies it. For underground (underwater, aerial) seismic wells, gravity observation stations, meteorological observation stations and other occasions that require long-term uninterrupted data acquisition, the collector must have the ability of fast data acquisition system acquisition rate and wireless data transmission. ; On the other hand, it needs to be small in size, low in power consumption, and resistant to vibration and shock to meet the special requirements of environmenta...

Problems solved by technology

For underground (underwater, aerial) seismic wells, gravity observation stations, meteorological observation stations and other occasions that require long-term uninterrupted data acquisition, the collector must have the ability of fast data acquisition system acquisition rate and wireless data transmission. ; On the other hand, it needs to be small in size, low in power consumption, and resistant to vibration and shock to meet the special requirements of environmental conditions. At present, the traditional wired data acquisition system can no longer meet the above requirements.
