Embodiment Construction

[0016] Attached below figure 1 The present invention is further described.

[0017] The present invention it comprises computer bus, is characterized in that, whole method is made up of following several steps:

[0018] Step 1: The computer bus controls the transmit data flow:

[0019] The second step: computer bus control to receive data;

[0020] The third step: computer bus control algorithm process data flow;

[0021] Among them, the computer bus controls the transmission data flow by the combined plug-in transmission data control drive module; the computer bus control receives the data by the combined plug-in reception data control drive module; the computer bus control algorithm process data flow is realized by DSP and FPGA Configurable control algorithm module for phased array detection.

[0022] Implementation of the present invention:

[0023] (1) Computer bus control transmit data flow

[0024] A single launch board can control a maximum of 16 channels of launc...

Abstract

The present invention discloses one design method of hardware platform with computer bus for phase control array supersonic detection, and aims at providing one hardware platform with high detection precision, light weight, flexible detection size, no ray related hazard, raised fault resolution and low operation cost. The present invention includes computer bus and consists of the following steps: controlling emitted data flow with computer bus; controlling the data receiving with computer bus; and controlling algorithm data flow with computer bus. In controlling emitted data flow with computer bus, the resultant plug-and-play emitting data control the drive module; in the controlling the data receiving with computer bus, the resultant plug-and-play receiving data control the drive module; and in the controlling algorithm data flow with computer bus, DSP and FPGA realized configurable control algorithm module for phase control array detection.

Description

technical field [0001] The invention relates to a hardware platform design method, more specifically, it relates to a hardware platform design method for a computer bus used in phased array ultrasonic detection. Background technique [0002] At present, in many construction projects, the fully automatic welding process has been used, which has brought about the development direction of fully automatic ultrasonic testing, that is, ultrasonic testing will gradually replace ray testing as the main testing method. [0003] Chinese patent "phased array ultrasonic instrument and detection method thereof" (application number: 01131936.4 publication number is: CN1412551A), discloses phased array ultrasonic instrument and detection method thereof, and it comprises ultrasonic probe part, transmitting part, receiving part, main body The control circuit part and the auxiliary part; the transmitting circuit part first selects the transmitting chip group according to the requirements, and...
