[0038] Refer to Figures 1 to 4 , through the setting of the clamping mechanism 1, this continuous renal replacement therapy alarm device can assist in installing this device on the filter of the CRRT device for use. The blood coagulation monitoring structure on the fixing member 101 can monitor whether there are blood clots in the filter. When a blood clot is detected, an alarm can be given by the alarm; through the setting of the first adjustment mechanism 102, the distance between the clamping members 107 can be adjusted to facilitate the adjustment of the monitoring distance. The bidirectional screw 1021 can drive the moving blocks 1023 at both ends to move bidirectionally, thereby adjusting the distance between the two fixing members 101, which can increase the practicality of the device.

[0046] refer to Figure 1 The visual sensor uses the Omron FQ-D30 touch detector, which is powered by a DC power supply and supports multiple power supply modes such as AC / DC / battery. It also has AI image recognition application functions. Its main principles are:
[0047] A visual sensor is a device that converts optical signals into electrical signals. Its principle can be expanded from the core links of optical signal reception, photoelectric conversion, signal processing and output. The following is a detailed analysis:
[0048] 1. Optical signal reception: The optical system captures the scene
[0049] The front end of a visual sensor is typically equipped with a lens and filters to collect and filter light from the environment: Lens: Focuses light reflected or emitted by the target object, forming an optical image and projecting it onto the photosensitive element. Lens parameters such as focal length and aperture determine the image clarity, field of view, and light intake. Filter: An optional component used to filter specific wavelengths of light (such as infrared, ultraviolet, or specific colors) to reduce ambient light interference and improve image contrast. For example, infrared filters are often used in industrial inspections to eliminate interference from visible light.
[0050] 2. Photoelectric conversion: The photosensitive element converts the light signal into an electrical signal
[0051] The core component is the image sensor. Its operating principle: When light strikes a CCD pixel, photons excite the semiconductor material (such as silicon) to generate charge (electron-hole pairs). This charge accumulates within the pixel, proportional to the light intensity. Subsequently, controlled by a clock pulse, the charge is transferred row by row within the CCD to the output amplifier, where it is converted into a voltage signal. Its characteristics include high sensitivity, low noise, and excellent image quality, making it particularly suitable for low-light environments.
[0052] 3. Signal Processing: From Analog Electrical Signals to Digital Images
[0053] The analog voltage signal obtained by photoelectric conversion needs to go through a series of processing to finally form a digital image: Amplification and filtering: The analog front-end circuit (AFE) amplifies the weak electrical signal (such as the CCD output signal requires high-gain amplification) and removes high-frequency noise through low-pass filtering. Analog-to-digital conversion: The analog voltage signal is converted into a digital signal (such as 8-bit, 10-bit or 12-bit binary data). The quantized value corresponds to the grayscale value of the pixel (black and white image) or RGB color value (color image). Image processing algorithm (built-in in some sensors): Correct the digital signal (such as bad pixel correction, white balance adjustment), reduce noise, correct distortion, etc. to improve image quality. For example, industrial vision sensors may have built-in edge detection and contrast enhancement algorithms to facilitate subsequent target recognition.
[0054] 4. Signal output and application
[0055] The processed digital image is output to back-end devices (such as computers and controllers) through interfaces. Common interfaces include: USB, GigE (Gigabit Ethernet), and Camera Link: used to transmit image data, suitable for scenarios such as industrial inspection and machine vision. MIPI and LVDS: low-power, high-speed interfaces, commonly used in embedded devices such as mobile phones and automotive cameras.
[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
