[0017] Figure 1 This is a block diagram of a bulk cargo port unmanned material taking flow rate regulation system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] The embodiment of the present invention provides a bulk cargo port unmanned operation material taking flow rate regulation method, the method can be implemented by a bulk cargo port unmanned operation material taking flow rate regulation system, the block diagram of the system is as follows Figure 1 As shown. The method comprises: step 1, arranging a material taking device at the bulk cargo port, wherein the material taking device comprises a material taking mechanism, a conveying mechanism and a discharge mechanism, the conveying mechanism is arranged between the material taking mechanism and the discharge mechanism, a first pressure sensor is arranged at the material taking mechanism, and a second pressure sensor and a third pressure sensor are arranged at the starting point and the end point of the conveying mechanism respectively; step 2, extracting materials from the storage facility of the bulk cargo port by the material taking device, and transferring the materials to the material receiving device, and the specific process comprises: controlling the material taking mechanism to extract materials from the storage facility in batches, detecting a first pressure value of the material taking mechanism by the first pressure sensor, determining a first weight value of the materials extracted by the material taking mechanism in the current batch according to the first pressure value, detecting a second pressure value of the starting point of the conveying mechanism by the second pressure sensor, determining a second weight value of the materials carried by the starting point of the conveying mechanism according to the second pressure value, and if the second weight value is greater than 0, controlling the The material taking mechanism suspends transferring the materials extracted in the current batch to the starting point of the conveying mechanism until the second weight value decreases to 0, controls the material taking mechanism to transfer the materials extracted in the current batch to the starting point of the conveying mechanism, causes the second weight value to increase to be consistent with the first weight value, and controls the material taking mechanism to return to the storage facility to extract the next batch of materials; controls the conveying mechanism to continuously convey the received materials to the unloading mechanism, controls the unloading mechanism to transfer the received materials to the material receiving device, detects the third pressure value of the terminal position of the conveying mechanism through the third pressure sensor, determines the third weight value of the material carried by the terminal position of the conveying mechanism according to the third pressure value, and if the third weight value is greater than a set first weight upper limit, controls the unloading mechanism to increase the unloading speed of transferring the received materials to the material receiving device until the third weight value decreases to below the first weight upper limit, and the unloading mechanism operates at the current unloading speed.

[0020] Specifically, in the process of extracting materials by the material-retrieving device, the material-retrieving mechanism extracts materials from the storage facility in batches. In the existing method, the material-retrieving speed of the material-retrieving mechanism is generally constant, that is, after the material-retrieving mechanism retrieves the materials each time, it immediately transfers the materials to the conveying mechanism, and then transfers them to the storage facility to continue to retrieve the materials. However, this method does not take into account the carrying capacity of the conveying mechanism, does not work in coordination with the conveying mechanism, and easily causes the materials to pile up in the conveying mechanism. In order to solve the above problems, the present invention sets a first pressure sensor in the material-retrieving mechanism for detecting the first pressure value of the material-retrieving mechanism, and sets a second pressure sensor at the starting point of the conveying mechanism for detecting the second pressure value at the starting point of the conveying mechanism. According to the first pressure value and the second pressure value, the first weight value of the current batch of materials extracted by the material-retrieving mechanism and the second weight value of the materials carried at the starting point of the conveying mechanism can be determined respectively. If the second weight value is greater than 0, it means that the conveying mechanism has not yet transported the materials that the material-retrieving mechanism transferred to the starting point of the conveying mechanism last time. At this time, if the material-retrieving mechanism directly puts the materials into the conveying mechanism, it may cause the conveying mechanism to be overloaded, or cause the materials to pile up in the conveying mechanism. Therefore, when the second weight value is greater than 0, the present invention controls the material taking mechanism to enter the waiting mode, suspends the transfer of the current batch of materials to the conveying mechanism, until the conveying mechanism conveys the materials at the starting position away, so that the second weight value is reduced to 0, and then controls the material taking mechanism to transfer the current batch of materials to the starting point of the conveying mechanism. When all the materials in the material taking mechanism are transferred to the starting position of the conveying mechanism, the second weight value will increase to be consistent with the first weight value, indicating that the transfer of the materials is completed, and the material taking mechanism will return to the storage facility to extract the next batch of materials, and the conveying mechanism will continue to transport the materials to the unloading mechanism.

[0021] In the existing method, the unloading speed of the unloading mechanism is also constant, that is, no matter how much material the conveying mechanism carries, the unloading mechanism takes material from the conveying mechanism at a fixed speed and then transfers the material to the material receiving device. However, this method does not take into account the carrying capacity of the conveying mechanism, does not work in coordination with the conveying mechanism, and easily causes the material to pile up in the conveying mechanism. To solve this problem, the present invention sets a third pressure sensor at the end point of the conveying mechanism, and detects the third weight value of the material carried by the end position of the conveying mechanism through the third pressure sensor. If the third weight value is greater than a set first weight upper limit, the unloading mechanism is controlled to increase the unloading speed, and the speed of transferring the material from the conveying mechanism to the material receiving device is accelerated until the third weight value is reduced to below the first weight upper limit, and the unloading mechanism can operate at the current unloading speed.

[0022] Through the above process, the present invention arranges pressure sensors at the starting point and end point of the material picking mechanism and the conveying mechanism respectively, collects pressure data in real time, determines the material weight data in the material picking mechanism and the conveying mechanism according to the pressure data, and then controls the material picking operation of the material picking mechanism and the material unloading operation of the unloading mechanism according to the material weight data in the material picking mechanism and the conveying mechanism, thereby improving the coordination and cooperation effect among the material picking mechanism, the conveying mechanism and the unloading mechanism, thereby realizing automatic adjustment of the material picking flow rate of the bulk cargo port, eliminating manual control, and ultimately improving the accuracy and efficiency of the material picking flow rate control.

[0023] In a preferred embodiment, in the unmanned material handling flow regulation method for a bulk cargo port, in the step one, a fourth pressure sensor is provided at the unloading mechanism; in the step two, a fourth pressure value of the unloading mechanism is detected by the fourth pressure sensor, and a fourth weight value of the material received by the unloading mechanism is determined according to the fourth pressure value; when the fourth weight value is less than a set lower weight limit, the conveying mechanism is controlled to increase the conveying speed of continuously conveying the received material to the unloading mechanism until the fourth weight value is increased to above the lower weight limit, and the conveying mechanism operates at the current conveying speed.

[0024] The present invention also provides a fourth pressure sensor in the unloading mechanism for detecting a fourth pressure value of the unloading mechanism, and a fourth weight value of the material received by the unloading mechanism can be determined according to the fourth pressure value. When the fourth weight value is less than a set weight lower limit, indicating that the unloading mechanism is not fully operating, the conveying mechanism is controlled to increase the conveying speed to improve the efficiency of transferring the material to the unloading mechanism.

[0025] In a preferred embodiment, in the unmanned material handling flow regulation method for a bulk cargo port, in the step 2, when the fourth weight value is greater than a set second weight upper limit, the unloading mechanism is controlled to increase the unloading speed of transferring the received material to the material receiving equipment until the fourth weight value is reduced to below the second weight upper limit, and the unloading mechanism operates at the current unloading speed.

[0026] Correspondingly, when the fourth weight value is greater than the second weight upper limit, it indicates that the unloading mechanism is at risk of overloading, and the unloading speed needs to be improved. Therefore, the unloading mechanism is controlled to increase its unloading speed.

[0027] An experiment can be conducted in advance to test the relationship between the first pressure value detected by the first pressure sensor and the first weight value of the material in the material-taking mechanism, and then the first weight value can be calculated in actual work based on the measured first pressure value and the relationship between the first pressure value and the first weight value. The same method can also be used to determine the relationship between the second pressure value at the starting position of the conveying mechanism and the second weight value of the material carried at the starting position, and then the second weight value can be calculated in actual work based on the measured second pressure value. Similarly, the relationship between the third pressure value at the terminal position of the conveying mechanism and the third weight value carried at the terminal position and the relationship between the fourth pressure value of the unloading mechanism and the fourth weight value of the material carried by the unloading mechanism can be determined, and then the third weight value can be calculated in actual work based on the measured third pressure value, and the fourth weight value can be calculated based on the measured fourth pressure value.

[0028] In a preferred embodiment, in the unmanned material taking flow rate regulation method for bulk cargo port, in step one, the material taking mechanism, the conveying mechanism and the unloading mechanism are all connected to a remote control center for communication; in step two, the first pressure value, the second pressure value, the third pressure value, the fourth pressure value, the first weight value, the second weight value, the third weight value and the fourth weight value are all sent to the remote control center, and the working status of the material taking mechanism, the conveying mechanism and the unloading mechanism are sent to the remote control center, the working status of the material taking mechanism includes extracting materials from the storage facility, transferring the materials extracted in the current batch to the starting point of the conveying mechanism and suspending the transfer of the materials extracted in the current batch to the starting point of the conveying mechanism, the working status of the conveying mechanism includes continuously conveying the received materials to the unloading mechanism and the conveying speed of continuously conveying the received materials to the unloading mechanism, and the working status of the unloading mechanism includes transferring the received materials to the material receiving device and the unloading speed of transferring the received materials to the material receiving device.

[0029] The present invention controls the material taking mechanism, the conveying mechanism and the unloading mechanism, and calculates and processes the pressure data and the weight data, which can be completed by the control device arranged in the material taking device, or by the remote control center. The control device can send various pressure data, weight data and the working state parameters of the material taking mechanism, the conveying mechanism and the unloading mechanism to the remote control center, which can perform unified monitoring.

[0030] In a preferred embodiment, the method for regulating the flow rate of unmanned material reclaiming in a bulk cargo port further includes step three, changing the working states of the reclaiming mechanism, the conveying mechanism and the unloading mechanism through the remote control center.

[0031] The control personnel can change the working status of the material picking mechanism, conveying mechanism and unloading mechanism through the remote control center, such as adjusting the picking speed of the material picking mechanism, the conveying speed of the conveying mechanism and the unloading speed of the unloading mechanism, etc., thereby improving the effect of the coordinated work between the material picking mechanism, the conveying mechanism and the unloading mechanism based on the automatic calculation of the control device.

[0032] In a preferred embodiment, in the unmanned material picking flow regulation method for the bulk cargo port, in the step three, when the working states of the material picking mechanism, the conveying mechanism and the unloading mechanism are changed through the remote control center, the working states of the material picking mechanism, the conveying mechanism and the unloading mechanism are first switched to stop working, and then the working states of the material picking mechanism, the conveying mechanism and the unloading mechanism are reset, and then the material picking mechanism, the conveying mechanism and the unloading mechanism are controlled to work according to the reset working states.

[0033] When changing the working status of the material picking mechanism, conveying mechanism and unloading mechanism through the remote control center, first switch the working status of the three to stop working, and then reset the working status of the three, which can ensure the safety and reliability of the working of the material picking mechanism, conveying mechanism and unloading mechanism, and avoid safety hazards caused by operation mismatch between mechanisms due to switching working status.

[0034] In a preferred embodiment, in the unmanned material reclaiming flow rate regulation method for bulk cargo ports, the reclaiming mechanism is a grab bucket, the conveying mechanism is a reclaiming conveyor belt, the unloading mechanism is a unloading conveying mechanism; and the material receiving equipment includes a material transfer vehicle.

[0035] In summary, the present invention arranges pressure sensors at the starting and ending positions of the material picking mechanism, the conveying mechanism and the unloading mechanism respectively, collects pressure data in real time, determines the material weight data in the material picking mechanism, the conveying mechanism and the unloading mechanism according to the pressure data, and then controls the material picking operation of the material picking mechanism, the unloading operation of the unloading mechanism and the conveying operation of the conveying mechanism according to the material weight data in the material picking mechanism, the conveying mechanism and the unloading mechanism, thereby improving the coordination and cooperation between the material picking mechanism, the conveying mechanism and the unloading mechanism, thereby realizing automatic adjustment of the material picking flow rate of the bulk cargo port, eliminating manual control, and ultimately improving the accuracy and efficiency of the material picking flow rate control.
