Example (b):

as shown in fig. 1-3, the utility model provides a pipeline blockage early warning system based on a single chip microcomputer, which comprises a fixing frame 1 in a U-shaped structure, wherein the fixing frame 1 comprises a U-shaped pipe 11, inner rods 12 are movably inserted at the shaft end of the U-shaped pipe 11, adjusting screws 16 are connected to the two inner rods 12 in a radial threaded manner, an ultrasonic transducer 2 is rotatably connected between the two adjusting screws 16, and the ultrasonic transducer 2 comprises an ultrasonic transducer transmitter 21 rotatably connected to the adjusting screw 16 on one side and an ultrasonic transducer receiver 22 rotatably connected to the adjusting screw 16 on the other side.

When the device is used, the ultrasonic transducer transmitter 21 and the ultrasonic transducer receiver 22 are adjusted to move relatively or away from each other by rotating the adjusting screw rod 16, so that the ultrasonic transducer transmitter 21 and the ultrasonic transducer receiver 22 can be attached and detected to two sides of pipelines with different pipe diameters, and meanwhile, the distance between the ultrasonic transducer 2 and the cross rod of the U-shaped pipe 11 can be conveniently adjusted by sliding adjustment of the inner rod 12 in the U-shaped pipe 11 during use, so that the device can be conveniently adjusted and used for pipelines with different pipe diameters, and the practicability is improved;

the ultrasonic transducer 2 uses an ultrasonic pulse reflection method, and its operation principle is well known to those skilled in the art: when ultrasonic waves are incident into a measured object by using a single or double sensor, reflection is generated when the ultrasonic waves encounter interfaces with different acoustic impedances, and a received ultrasonic echo signal is processed. Due to the different material structures, when ultrasound propagates in inhomogeneous tissue or from one material to another, reflection, refraction and transmission will occur at the interface where the acoustic impedance changes due to the different acoustic impedances of the materials. Therefore, the physiological characteristics of the tissue can be probed by using an ultrasonic pulse reflection method and adopting the same transducer to transmit and receive signals and then receiving ultrasonic echoes reflected back from the inside of the body. The ultrasonic radio frequency echo signal is a waveform which is directly added to the display of the oscilloscope after a probe reflection signal is amplified by the amplifier. Due to different structural compositions of materials, the medium layers have different sound velocity, sound attenuation, sound impedance and other ultrasonic properties, and the amplitude, the phase, the wave number density, the rising edge and the falling edge of the received ultrasonic radio-frequency echo signal are different. As long as the ultrasonic radio frequency echo distribution characteristics of all tissue layers are determined, the identification can be carried out according to different characteristics so as to detect the thickness of all materials.

The ultrasonic transducer 2 is adopted to measure the thickness of the scale in the pipeline and give an early warning on the condition that the sewer is about to be blocked, and the method can greatly reduce the economic cost caused by blocking. The thickness of the scale is converted into the transmission speed of the measured sound wave, and then the transmission speed of the sound wave is converted into the transmission time of the measured sound wave. As long as the transmission time of the sound wave can be measured, the thickness of the scale in the pipeline can be deduced, the inner diameter of the pipeline is calculated, and reminding is carried out according to a preset standard value.
