Problems solved by technology

However, due to the increase of acquisition and processing traffic in high-speed acquisition, this solution cannot meet the requirements because it uses a 16-bit ISA bus.
With the continuous development and deepening of networking, real-time network monitoring of processing information is required, and the current solution cannot meet high-speed performance requirements only by adding network cards
In addition, the overall cost of the signal acquisition board and industrial computer is relatively high, and the resource utilization rate is relatively low, so it is not suitable for industrialized development

Embodiment Construction

[0014] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the embodiments should not be construed as limiting the present invention.

[0015] like figure 1 As shown, the hardware module is mainly composed of: high-speed acquisition signal source, high-precision function generator for 16-bit DA conversion, DSP signal acquisition and processing module, sensor system protection and stability module, CAN bus communication module, upper computer communication module, etc. Partial composition. The DSP processing chip adopted in the present invention is the TMS320F2407 or TMS320C5402 dedicated signal processing module of Ti Company in the United States. First, the high-speed acquisition signal source can convert the optical pulse signal in the fiber grating demodulator into a low-frequency analog electrical pulse signal, and then the DSP signal acquisition and processing module samples, weights and quantizes th...

Abstract

This invention relates to a monitor system based on an inserted intelligent high speed signal acquisition composed of a high speed acquisition signal source a 16 bit DA converted high precision function generator, a transducer system protection and a stable module, a communicaiotn module, RS232 / USB communication module, LCD dynamic display module, 10M / 100M network communication module and a signal storage module based on USB interval characterizing in connecting a DSP signal acquisition and process module between the acquisition and RS232 / USB input of which is connected with the output of high speed acquisition, its output is linked to the RS232 / USB input of ARM is connected with RS / 232 / USB and LCD, output of which is connected with 10M / 100m and the signal storage module.

Description

technical field [0001] The invention belongs to a monitoring technology in a computer network, in particular to a monitoring system based on embedded intelligent high-speed signal collection. Background technique [0002] At present, the hardware architecture method based on signal acquisition and processing basically adopts the scheme of "measurement and control card + industrial computer", that is, the ready-made signal acquisition board is inserted into the industrial computer. This method has the advantages of good stability and strong versatility. However, due to the increase of collection and processing traffic in high-speed collection, this solution cannot meet the requirements because it uses a 16-bit ISA bus. With the continuous development and deepening of networking, real-time network monitoring of processing information is required, but the current solution cannot meet the high-speed performance requirements only by adding network cards. ...
