[0056] Example 2

[0057] Based on Example 1, Figure 2 As shown, this embodiment provides a glass fiber sand cylinder production automation control method, comprising the following steps:

[0058] Step 1): The first monitoring module monitors the water flow pressure in the sand tank body, and the first regulating module regulates the water flow pressure in the sand tank body; wherein the water flow direction vector method is used to monitor the pressure of the water flow direction;

[0059] Step 2): the second monitoring module uses a vector collision method to monitor the collision force of the water flow on the filter sand in the sand cylinder body, and the second regulating module regulates the water flow pressure in the sand cylinder body according to the monitored collision force of the water flow on the filter sand in the sand cylinder body;

[0060] Step 3): The real-time monitoring and control unit monitors and controls the water flow pressure in the sand cylinder body in real time;

[0061] Step 4): After filtering the water flow through the filter sand, the real-time monitoring and control unit monitors the conductivity of the water flow.

[0062] Specifically, in step 1), after monitoring the water flow pressure in the sand cylinder body, the water flow pressure in the sand cylinder body is regulated according to whether the water flow in the sand cylinder body becomes a linear flow state.

[0063] In step 1), the water flow direction vector method uses the following formula (1):

[0064] (1);

[0065] in, is the displacement of the water flow at the i-th position, and the water flow displacement flows from one direction to another; is the pressure at the ith displacement of the water flow; There is pressure corresponding to the i-th displacement of the water flow; Represents the operation of connecting the pressure data corresponding to each displacement of the water flow; To randomly select and monitor the pressure corresponding to a displacement of the water flow, An operating function for randomly selecting and monitoring the pressure at a displacement of the water flow;

[0066] The pressure corresponding to each displacement of the water flow is aggregated. In order to monitor whether the pressure corresponding to each displacement of the water flow is in the direction of the water flow, To monitor whether the pressure corresponding to each displacement of the water flow is in the direction of the water flow, To monitor whether the water flow is in a straight line.

[0067] In addition, in step 1), the water flow vector method adopts the following steps:

[0068] Step 11): Aggregate the pressures corresponding to each displacement of the water flow;

[0069] Step 12): monitoring the pressure corresponding to each displacement of the water flow;

[0070] Step 13): Monitor whether the pressure corresponding to each displacement of the water flow is in the direction of the water flow.

[0071] In step 2), the vector collision method uses the following formula (2):

[0072] (2);

[0073] in, is the i-th water stream that hits the filter sand. The water stream is directed toward the filter sand. Colliding filter sand, the total number of water flow beams is N; The size of the sand filtering area can be adjusted; The adjustable sand filter area There are N water streams colliding with the filter sand;

[0074] Sand filter area The average collision force of N water streams on the surface; The obtained filter sand area The average collision force of N water streams on the surface.

[0075] In addition, in step 2), the vector collision method adopts the following steps:

[0076] Step a): monitoring the number of multiple water streams directed toward the filter sand;

[0077] Step b): setting the filter sand area where multiple water streams collide with the filter sand;

[0078] Step c): Calculate the average impact force of multiple water streams on the filter sand area.

[0079] In step 3), whether the water flow in the sand cylinder body is in a straight-line flow state is monitored and controlled in real time to determine whether the pressure corresponding to each displacement of the water flow is in the direction of the water flow.

[0080] In step 4), the conductivity of the water flow after being filtered by the filter sand is monitored to facilitate the control of the filtering of tiny dirt particles and organic matter in the filtered water flow by the filter sand.

[0081] Example 3

[0082] Based on Example 2, Figure 3-Figure 4As shown, the formula (1) based on the water flow direction vector method or the steps of the water flow direction vector method.

[0083] Water displacement from one direction to another ( Figure 3 The straight line direction), is the displacement of the first position of the water flow, is the displacement of the water flow at the ith position, is the displacement of the water flow at the Nth position.

[0084] The displacement of each point on the water flow flows in the direction of the water flow, and the water flow is in a straight line. In this way, the water flow pressure in the sand tank body can be monitored and regulated.

[0085] like Figure 4 The figure shows the displacement of the i-th position of the water flow. Originally, the displacement of the i-th position on the water flow is flowing in the direction of the water flow (i.e. Figure 4 solid arrow direction), if the displacement at the i-th position on the water flow is offset from the flow direction (i.e. Figure 4 The water flows in the direction of the dotted arrow), and the water flow will not be in a straight line. This can also monitor the water flow pressure in the sand tank body and regulate the water flow pressure in the sand tank body.

[0086] Example 4

[0087] Based on Example 2, Figure 5-Figure 7 As shown, the following formula (2) based on the vector collision method or the steps of the vector collision method.

[0088] like Figure 5 As shown, under normal circumstances, when the filter sand area is fixed, multiple water streams are directed toward the filter sand, and an average collision force of the fixed filter sand area impacted by N water streams can be obtained.

[0089] like Figure 6 As shown, under abnormal circumstances, when the filter sand area is adjustable, multiple water streams are directed toward the filter sand, among which some water streams are deviated and then directed toward the filter sand. The filter sand area needs to be increased to obtain the average collision force of the adjusted filter sand area subjected to the collision of N water streams.

[0090] Similarly, if Figure 7 As shown, under abnormal circumstances, when the filter sand area is adjustable, multiple water streams are directed toward the filter sand, among which some water streams are deviated and then directed toward the filter sand. The filter sand area needs to be reduced to obtain the average collision force of the adjusted filter sand area subjected to the collision of N water streams.

[0091] Based on all the above embodiments, the present invention adopts the water flow direction vector method to monitor the pressure of the water flow direction, and adopts the vector collision method to monitor the collision force of the water flow on the filter sand in the sand cylinder body. Both of them adjust the pressure of the water flow direction and the collision force of the filter sand in the sand cylinder body according to the actual situation of monitoring the water flow.

[0092] The computer program involved in the present application can be stored in a computer-readable storage medium, which may include: any physical device, virtual device, USB flash drive, mobile hard disk, magnetic disk, optical disk, computer memory, read-only computer memory (ROM), random access computer memory (RAM), electrical carrier signal, telecommunication signal and other software distribution media, etc. that can carry computer program code.
