A general FPGA synchronous trigger controller and method with trigger monitoring

Abstract

The invention discloses a general FPGA synchronous trigger controller with trigger monitoring function and a method thereof. The general FPGA synchronous trigger controller comprises a synchronous trigger control module, a camera module, a system control module and a stepping control module, wherein the system control module is used for receiving image information transmitted by the camera module,sending setting parameters, receiving error reporting information and processing the error reporting information; the synchronous trigger control module is used for receiving the setting parameters,synchronizing a working state according to the setting parameters and receiving a stepping motion in-place trigger signal, and starting trigger monitoring; the stepping control module is used for outputting the stepping motion in-place trigger signal to the synchronous trigger control module after the stepping is finished; and the camera module is used for receiving the synchronous trigger signal,controlling the camera to synchronously acquire the information of a measuring point and simultaneously sending the picture information to the system control module. The input and output of the trigger signal of the synchronous trigger controller in a stepping measurement system are monitored, and meanwhile, the stability and the intelligence of the stepping measurement system are improved.

Description

technical field [0001] The invention relates to the technical field of step measurement synchronous control, in particular to a general-purpose FPGA synchronous trigger controller and method with trigger monitoring. Background technique [0002] At present, in the field of detection and measurement, many step-by-step measurement systems need to use a synchronous controller to synchronously trigger multiple external devices, such as light sources, cameras, etc. image. [0003] At present, most of the synchronous trigger controllers used in the field of step measurement are based on FPGA design, and are implemented by hard synchronization. Compared with soft synchronization, the accuracy and time overhead of synchronous triggering have been greatly improved. However, with the improvement of the stability and intelligence requirements of the measurement system, the step measurement system requires the synchronous trigger controller to not only realize the function of synchrono...

Problems solved by technology

[0003] At present, most of the synchronous trigger controllers used in the field of step measurement are based on FPGA design, and are implemented by hard synchronization. Compared with soft synchronization, the accuracy and time overhead of synchronous triggering have been greatly improved. However, with the improvement of the stability and intelligence requirements of the measurement system, the step measurement system requires the synchronous trigger controller to not only realize the function of synchronous trigger, but also monitor its own working status. Once an abnormality occurs, it can be reported and processed. Obviously, the current general-purpose FPGA-based synchronous trigger controller cannot meet the requirements of trigger monitoring
