Abstract

An intelligent triggering device based on an embedded system comprises a power supply and further comprises an ARM (Advanced RISC Machines) system board, a signal acquisition module and a signal trigger module, wherein the signal acquisition module is used for completing real-time acquisition of a multi-channel data signal and outputting the signal to the ARM system board through an I2C bus interface; the ARM system board receives the acquired data signal in real time, processes the multi-channel data signal in real time by using a built-in data processing model, generates triggering data when built-in triggering strategies are met, and outputs the triggering date through a GPIO (General Purpose Input / Output) interface; and communication between the signal trigger module and the ARM system board is realized by the GPIO interface, and the signal trigger module generates a corresponding triggering signal according to the triggering data. According to the device, the real-time acquisition of the multi-channel data signal, synchronous and efficient data analysis, and timely outputting of the trigger signal are realized. The invention further provides a control method of the device.

Description

technical field [0001] The invention relates to a signal triggering device, in particular to a signal triggering device based on an embedded system. Background technique [0002] At present, in the material mechanics test, it is not only necessary to record the data of sensors such as load and displacement, but also to take photos of the deformation and failure process of the sample simultaneously. When shooting with an ordinary camera, the shutter can be manually controlled and the load or displacement during shooting can be recorded. Although the synchronization error is not very large, if the shooting interval is short, the experimental operation is still very cumbersome and the workload is heavy. If a high-speed camera is used to shoot, because hundreds of thousands or even hundreds of thousands of frames of photos are taken in one second, the error caused by manual control of the shutter is very large. Not only was the synchronization poor, sometimes the timing of the...
