Example Embodiment
[0041] Example 1
[0042] This embodiment is a remote control system for intelligently monitoring material deposition in pipelines in pneumatic conveying (see Figure 1-4 ), including: double casing 1 , deposition detection terminal 2 , wired communication module 3 , main controller 4 , wireless communication module 5 , cloud server 6 , and mobile phone client 7 . The deposition detection terminals 2 are laid on the lower pipe wall at the bottom of the double casing 1, and the distance between two adjacent deposition detection terminals 2 is set to 2m. The deposition detection terminal 2 is connected with the main controller 4 through the wired communication module 3, the wired communication module 3 adopts the 485 bus, the main controller 4 is connected with the cloud server 6 through the wireless communication module 5, the wireless communication module adopts the Lora wireless module, and the cloud server 6 It is also connected with the mobile phone client 7 through the wi...

[0054] Example 2
[0055] The positions and connection relationships of each part in a remote control system for intelligently monitoring material deposition in pipelines in pneumatic conveying in this embodiment are the same as those in Embodiment 1 (see figure 1 ). The difference is that the outline shape of the capacitive antenna 21 is changed to a circular outline structure (see Figure 7 ), and the insulating sheet 22 has the same size as the capacitive antenna 21, has a diameter of 20 cm, can be freely bent, and is connected to the bottom of the pipe by welding. The capacitive antenna 21 can satisfy S 11 A requirement that is positively related to the thickness of the deposited layer. In this embodiment, the distance between two adjacent deposition detection terminals 2 is set to 3m. The round profile is easy to install and fits better with the inner wall of the pipe.
[0056] The system in this embodiment can wirelessly monitor the deposition amount at multiple mon...

[0057] Example 3
[0058] The structure of this embodiment is the same as that of Embodiment 1, the difference is that the structure of the deposition detection terminal in this embodiment is: the width of the insulating sheet 22 and the capacitive antenna 21 is 1 cm, the length is 2 cm, and they are placed in a straight pipe section with a pipe diameter of 2 cm. . Using the structure in this embodiment, the total integral occupied by the material (solid phase) is 0.12 to carry out a pneumatic conveying simulation experiment, which is used to fit the relationship between the capacitance and the deposition quality,
[0059] Figure 8 Shown is the relationship between the measured capacitance of the capacitive antenna 21 and the deposition quality of the material particles. It can be seen that the capacitance value increases with the increase of the deposition quality of the material particles, and the relationship between the capacitance and the deposition quality is obtained ...
