Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The block diagram of the internal structure of the collector is as follows: figure 1 As shown, it is mainly divided into: control module, acquisition module and power module.

[0023] The acquisition module includes ADC and clock management. The ADC adopts the ADS42LB49 chip to realize the sampling function of 2 channels, the highest sampling rate 250MSPS, and 14bit precision. The clock management chip AD9517 realizes the switching between the internal clock and the external clock and the control of the sampling rate.

[0024] The control module includes FPGA, NANDFLASH, USB interface and front panel. FPGA judges the selection of internal and external clocks, trigger mode, sampling length, control of the acquisition process, etc. through the trigger signal on the front panel. Then the working status of the collector is displayed...

Abstract

The invention discloses a miniature signal collector, a user can control the working mode of the miniature signal collector by a panel button and dial switch, at the same time can monitor intuitively the working state of the miniature signal collector by an indicator lamp, and the miniature signal collector is easy to use. The collector is provided with a power adapter interface, and requirements of long time work can be met by power supplied by an external adapter. Signals can be stored by the miniature signal collector into internal NANDFLASH in real time, and data can be transmitted to an upper computer through a USB interface for data analysis. The miniature signal collector has the advantages of small size and convenient carrying, and the miniature signal collector can continuously work for more than 3 hours by optimization of power supply of an internal lithium battery.

Description

technical field [0001] The invention relates to the field of information collection, in particular to a micro collector. Background technique [0002] Among the existing signal collectors, most of them are large-scale complete equipment. When used in field tests, the equipment is large in size, heavy in weight, high in power consumption, and inconvenient to carry. Big inconvenience. Contents of the invention [0003] The invention discloses a miniature collector, which is small in size, convenient to carry, simple to use, has two power supply modes of built-in and external connection, and has long working time. [0004] In order to achieve the above object, the present invention adopts following scheme: [0005] A miniature collector, comprising an acquisition module, a control module and a power supply module, the acquisition module is electrically connected to the control module; the acquisition module includes an ADC and a clock management chip, and the ADC is connect...
