Embodiment 1
[0030] Such as figure 1 A bridge amplitude real-time monitor is shown, including a cursor device, an optical system, a CCD image acquisition module, an FPGA module and a processing unit; the cursor device forms a light spot and is installed on the bridge amplitude point, and the optical system images the cursor device on the CCD The image acquisition module receives the area array so that the CCD image acquisition module can receive the image information of the cursor device at a long distance. The FPGA module judges the bridge amplitude according to the center movement of the cursor device in the cursor device image before and after the bridge vibration, and the processing unit performs data processing on the output information of the FPGA module. Process, control each module and control the communication between each module.
[0031]When installing the cursor device, it is preferred to install it at the amplitude-sensitive point of the bridge. The optical system is aligned w...
Embodiment 2
[0033] Based on the principles of the above-mentioned embodiments, this embodiment refines its specific implementation, that is, the cursor device includes a light outlet, an LED light arranged at the light outlet, a driving circuit for driving the LED light, and a device for controlling the working state of the LED light. Photoelectric switch. The light of the LED lamp is emitted through the light outlet, and a beam shaper is installed on the light outlet. The shape of the light exit can be a circle, a square or a regular triangle, or an ellipse, a regular five-pointed star, an isosceles trapezoid, etc., preferably a circle, which reduces the amount of data calculated by the amplitude value of the image recognition feature in the later stage, and can Simplifies the difficulty of subsequent center identification. The circular feature is formed at the back of the circular light outlet, and the coordinates of the center point of the cursor are analyzed through image binarizatio...
