[0019] Preferably, a control method of a high-standard concrete mixing station intelligent control system is provided, and the specific control method is as follows: step one, the staff in the background of the mixing station sends a start signal to the controller through the wireless transmission module, after the controller receives the start signal, the second cylinder is controlled to extend to drive the main feeding pipe and the auxiliary feeding pipe to realize the descending action in the height direction of the mounting base, so that the main feeding pipe is inserted with the main feeding pipe, the two auxiliary feeding pipes are respectively inserted with the corresponding auxiliary feeding pipes, the electromagnetic valves on the surfaces of the main feeding pipe, the auxiliary feeding pipe, the main feeding pipe and the auxiliary feeding pipe are all powered on, the external feeding mechanism is controlled to send the required cement, sand and water of the concrete into the stirring bin according to a certain ratio, and then the feeding action in the stirring bin is realized, after the feeding is completed, the electromagnetic valves on the surfaces of the main feeding pipe, the auxiliary feeding pipe, the main feeding pipe and the auxiliary feeding pipe are all powered off, the second cylinder is controlled to retract to drive the main feeding pipe and the auxiliary feeding pipe to realize the ascending action in the height direction of the mounting base, so that the main feeding pipe is disengaged from the main feeding pipe, and the two auxiliary feeding pipes are disengaged from the corresponding auxiliary feeding pipes, in addition, the cooperation of the anode magnet and the cathode magnet makes the connection between the main feeding pipe and the main feeding pipe, and the two auxiliary feeding pipes and the corresponding auxiliary feeding pipes more stable.

[0021] Step 3: During the circular rotation of the support frame around the axis of rotation, the first connecting shaft is driven to rotate through the meshing of the first active bevel gear and the driven bevel gear groove.

By using the photoelectric switches on both sides of the conveyor belt, as well as the laser range sensor and measuring plate, the height difference of the concrete is measured, and the settlement slump can be obtained. The measurement is vertically fed back to the controller, which processes it and then transmits it remotely to the back-end terminal of the mixing plant through the wireless transmission module, so that the staff can remotely control the viscosity of the concrete after mixing.

[0025] Step seven, when the concrete viscosity reaches the actual needs, first control the third cylinder contraction, drive the measuring sleeve along the height direction of the installation base to realize the falling action, at this time, in order to make the concrete evenly fall on the surface of the conveying belt, the third cylinder is used to leave a gap between the measuring sleeve and the conveying belt for the concrete to flow, at this time, the measuring sleeve realizes the scraping treatment to the concrete falling on the surface of the conveying belt, secondly, through the cooperation of the rotating mechanism and the rotary encoder, drive the stirring bin to rotate 180 degrees along the X direction of the stirring bin, from the vertical state to the inverted state, finally, control the electromagnetic valve on the surface of the main feeding pipe to be electrified, realize the discharging action of the concrete in the stirring bin.
