[0031] The attitude detection module is used for detecting the running action of the loader 5, and the attitude detection module needs to be additionally provided with corresponding devices (such as sensors) on the loader 5. In this embodiment, the loader 5 can be manually driven or intelligently controlled.

[0032] In this embodiment, as shown, Figure 2As shown, the vehicle-mounted antenna 9 is arranged on the loader 5, and the base station positioning module is arranged in the whole stockyard 4, so that the position of the loader 5 in the stockyard 4 can be determined through the cooperation of the vehicle-mounted antenna 9 and the base station positioning module, such as knowing that the loader 5 is located in which stock bin 61, and also knowing that the loader 5 reaches the material distribution hopper 31 of the material machine 3, and the stock bin 61 and the material distribution hopper 31 have corresponding numbers and related information, so that the information of where the loader 5 loads the material and transports the material to which material distribution hopper 31 can be obtained, and the whole material transportation process can be tracked.

[0033] In an optional embodiment, the vehicle-mounted antenna 9 is installed on the top of the loader 5, which is used for the master terminal to obtain the real-time positioning data of the loader 5, and makes the received signal more stable, which is beneficial to the positioning of the position of the loader 5 in the stockyard 4. Moreover, the vehicle-mounted antenna 9 adopts waterproof design, which can be stably operated outdoors for a long time, and can ensure the safety of operation. When the loader 5 is a forklift, the vehicle-mounted antenna 9 is installed on the top of the forklift.

[0034] In this embodiment, the vehicle-mounted control terminal can be used only for display, and is provided with a display screen. Optionally, the data of the vehicle-mounted antenna 9 and the data of the attitude detection module 8 can be input into the vehicle-mounted control terminal, the vehicle-mounted control terminal obtains the real-time position information of the loader 5 in the stockyard 4 through the vehicle-mounted antenna 9 cooperating with the base station positioning module and records the real-time position information, the vehicle-mounted control terminal sends the real-time position information of the loader 5 in the stockyard 4 to the master terminal, and the vehicle-mounted control terminal has an external interface which can be connected to an external device for information interaction.

[0035] In this embodiment, the master terminal obtains the real-time positioning data of the loader 5 through the base station positioning module and the vehicle-mounted antenna 9, and judges the real-time position of the loader 5 in the stockyard 4. Specifically, the real-time positioning data of the loader 5 obtained through the base station positioning module and the vehicle-mounted antenna 9 can be stored in the vehicle-mounted control terminal and sent to the master terminal by the vehicle-mounted control terminal. The master terminal can send relevant loading operation instructions (operation instructions) and unloading operation instructions (operation instructions) to the vehicle-mounted control terminal according to the process flow and display them through the vehicle-mounted control terminal. When the loader 5 is manually controlled, the operator can determine the type of material to be loaded and the corresponding stock bin 61 label according to the loading operation instructions displayed on the vehicle-mounted control terminal, so as to accurately load the material. The operator can determine which material distribution hopper 31 of the material machine 3 the material loaded by the loader 5 at present should be unloaded into according to the unloading operation instructions displayed on the vehicle-mounted control terminal, so as to ensure accurate unloading.

[0036] The host terminal can determine whether the loader 5 has loaded and unloaded according to the real-time position of the loader 5 in the stockyard 4 and the operation action of the loader 5 detected by the attitude detection module 8; the host terminal can determine whether an alarm instruction needs to be sent to the vehicle-mounted control terminal according to the real-time position of the loader 5 in the stockyard 4 and the operation action of the loader 5; and the vehicle-mounted control terminal can send an alarm signal according to the alarm instruction.

[0037] As the host terminal has determined that the loader 5 has loaded 5-10 mm gravel coarse aggregate 1 in the second bin 61, the operator moves the loader 5 to the corresponding sand batching hopper 31 of the material machine 3 to prepare for unloading. Since the position is wrong and the unloading is prepared, the host terminal sends an alarm instruction to the vehicle-mounted control terminal, and the vehicle-mounted control terminal sends an alarm signal according to the alarm instruction, reminding the operator that the position of the batching hopper is wrong for unloading, and timely stopping the wrong loading (unloading) from occurring, which can avoid the need to clean the batching hopper 31 due to unloading errors.

[0038] In this embodiment, the host terminal is a program software system, which can also display stockyard 4 information and manage data. The host terminal software runs in an industrial computer, can obtain the loading (unloading) condition of the forklift in real time, and monitors and alarms the loading in real time according to the corresponding relationship between the bins and the batching hoppers configured by the user. At the same time, the host terminal is configured with a local database and an upload interface, and can realize real-time recording and network uploading of all operation data. The host terminal can be additionally configured with a stockyard information interface, so that the user can comprehensively master the stockyard operation condition, including the loading condition of each forklift, the loading information of the entire stockyard per day, etc., and provide simple and effective actual operation data information for stockyard managers.

[0039] The host terminal can collect and process production data from the feeding to the material mixing process of the stockyard 4, and can display the stockyard 4 information in real time through an electronic display board. The relevant data mainly includes the following contents: (1) The number of feeding vehicles, the type and number of feeding materials of the stockyard 4; (2) The corresponding bin, batching hopper, material type, time and other related information of the transferred material of the stockyard 4; (3) The correctness of the operation of the transfer loader 5; (4) Classification statistics of all transferred material types; (5) Daily statistics of the total amount of material transfer.

[0040] The related parameters and information of the work flow of feeding, taking material, dumping and other processes in the whole operation process are uploaded to the background server or cloud by the host terminal, which can be used by the user later. During the trial process, no error loading event occurs, at the same time, the types of feeding vehicles, material types and usage are accurately counted, which can further calculate the supply of the mixing station materials, the specific points are as follows: (1) The vehicles (including loaders 5) entering the silo 61 are all equipped with vehicle-mounted antennas 9, the vehicle-mounted antennas 9 have marks, and the vehicle-mounted antennas 9 cooperate with the base station positioning module 7 to realize real-time positioning of the vehicles in the silo 61 or the concrete mixing material taking loader 5.

[0041] (2) The silo 61 management system automatically judges whether the loading and feeding process of the loader 5 in the silo 61 is misloading or misfeeding.

[0042] (3) The host terminal can send relevant information to the vehicle-mounted control terminal of the corresponding loader 5 according to the process flow, realizing real-time updating of the feeding information.

[0043] (4) The error operation alarm system is used to realize that when the driver ignores the alarm information and makes an error dumping, the vehicle-mounted control terminal will send an alarm signal and return to the host terminal, and the mixer 1 automatically stops.

[0044] (5) The production data from the feeding to the material mixing process of the stockyard 4 can be collected and processed, and the stockyard 4 information can be displayed in real time through the electronic display board.

[0045] (6) The intelligent control recognition system is used to reduce the number of management personnel and save costs.

[0046] The concrete mixing station stockyard 4 intelligent monitoring system can effectively control the quality of the loading of concrete raw materials, ensure that concrete is not wasted or even abandoned due to incorrect loading, and has huge indirect benefits. The system can automatically judge the accuracy of the loading and feeding process of the loader 5 in the silo 61, avoid operation errors that lead to unqualified concrete quality, and reduce the working intensity of the operator and improve the working accuracy.

[0047] The system is connected with the mixing station production system, the loader operator transfers the material in the silo to the batching hopper according to the production system instruction, if the loader operator misloads the material, the vehicle-mounted control terminal in the loader cab sends an alarm reminder before the material is dumped; if the material is loaded into a non-corresponding silo, the cab sends an alarm reminder and sends a misloading signal to the production system, the production system stops, and after the misloaded material is removed, the production system resumes; the system records all the actions of the loader and the transfer and dumping process, which has traceability.

[0048] Example 2 AsFigure 4 As shown in the figure, a concrete mixing plant stockyard 4 operation management method adopts the intelligent monitoring system of the concrete mixing plant stockyard 4 described in Embodiment 1. During the whole material taking operation and material pouring operation, the host terminal judges the position of the loader 5 in real time according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5.

[0049] The concrete mixing plant stockyard 4 operation management method comprises the following steps: S1: The host terminal sends operation information to the vehicle-mounted control terminal of the corresponding loader 5 in the stockyard 4 according to the process flow, which can guide the material taking operation and material pouring operation, thereby improving the operation accuracy and efficiency; S2: Material taking operation: the loader 5 moves to the corresponding bunker 61 in the bunker area of the stockyard 4 according to the operation information received by the vehicle-mounted control terminal, and then the loader 5 loads the material; In step S2, the host terminal judges the position of the loader 5 according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5. If the loader 5 can load the material in the current bunker 61, the vehicle-mounted control terminal sends a prompt signal to perform the loading operation. This can greatly improve the efficiency and accuracy of loading and reduce the requirements for the operation experience and on-site observation ability of the loader 5 driver; In step S2, the host terminal judges the position of the loader 5 according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5. The host terminal detects the running action of the loader 5 through the attitude detection module 8 on the corresponding loader 5. The host terminal judges whether the loader 5 is ready to load according to the position of the bunker 61 where the loader 5 is located and the running action of the loader 5. If the loader 5 is ready to load and the position of the bunker 61 where the loader 5 is located is incorrect, the host terminal sends an alarm instruction to the vehicle-mounted control terminal, and the vehicle-mounted control terminal sends an alarm signal to prompt the change of the position of the bunker 61. Until the loader 5 reaches the correct bunker 61 and completes the loading, the next step is performed. The continuous alarm signal can better remind the driver and avoid the driver taking the material incorrectly, avoid the subsequent rework after finding the error, improve the operation efficiency and reduce the operation cost.

[0050] S3: Material pouring operation: the loader 5 moves to the corresponding batching hopper 31 in the stockyard 4; then the loader 5 pours the material into the corresponding batching hopper 31; In step S3, the host terminal judges the position of the loader 5 according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5. If the material transported by the loader 5 can be poured in the current batching hopper 31, the vehicle-mounted control terminal sends a prompt signal to perform the pouring operation. This can greatly improve the efficiency and accuracy of pouring and reduce the requirements for the operation experience and on-site observation ability of the loader 5 driver.

[0051] In step S3, the host terminal determines the position of the loader 5 according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5, detects the operation of the loader 5 through the attitude detection module 8 on the corresponding loader 5, and determines whether the loader 5 is ready to pour material according to the position of the loader 5 in the batching hopper 31 and the operation of the loader 5. If the host terminal determines that the position of the loader 5 in the batching hopper 31 is incorrect and the loader 5 is ready to pour material, the host terminal sends an alarm instruction to the vehicle-mounted control terminal, and the vehicle-mounted control terminal sends an alarm signal to prompt the replacement of the position of the batching hopper 31. The alarm signal continues until the loader 5 moves to the correct batching hopper 31 and completes the pouring of material. The continuous alarm signal can better remind the driver and greatly reduce the possibility of material pouring error, thereby improving the operation accuracy.

[0052] In step S3, if the driver still controls the loader 5 to pour material after the vehicle-mounted control terminal sends an alarm signal, the control terminal displays an error and pauses the mixing of the mixer, and then cleans the batching hopper 31 to avoid waste material after mixing and reduce the loss of error.

[0053] Embodiment 3 A concrete mixing plant yard management and control operation method adopts the intelligent monitoring system of a concrete mixing plant yard in embodiment 1. During the whole material taking operation and material pouring operation, the host terminal determines the position of the loader 5 in real time according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5.

[0054] The concrete mixing plant yard 4 management and control operation method comprises the following steps: S1: The host terminal sends operation information to the vehicle-mounted control terminal of the corresponding loader 5 in the yard 4 according to the process flow. In step S1, the operation information sent by the host terminal to the vehicle-mounted control terminal is a loading operation instruction. S2: Material taking operation: the loader 5 moves to the corresponding stock bin 61 in the stock bin area of the yard 4 according to the operation information received by the vehicle-mounted control terminal and in combination with the layout of the yard 4, and then the loader 5 loads material. In step S2, if the host terminal determines that the loader 5 has correctly loaded material, the host terminal records the material taking information of the loader 5, which includes the current stock bin 61 information, the material information stacked in the current stock bin 61, and the time information, etc. Specifically, when the loader 5 is a forklift, the forklift driver drives the forklift into the stock bin 61 according to the received operation information and in combination with the layout of the yard 4. The host terminal determines the position of the loader 5 according to the base station positioning module and the vehicle-mounted antenna 9 on the corresponding loader 5, and determines whether the loader 5 can load material in the current stock bin 61. If yes, the vehicle-mounted control terminal sends a prompt signal to perform the loading operation. When the shovel loader is loading in the stock bin 61, the host terminal can automatically judge the shovel loader state according to the posture detection module 8, and the host terminal judges whether the working shovel loader is in the state of loading according to the positioning information of the shovel loader and the action information of the working shovel loader, and records the current stock bin 61 information and the stacked material information if the loading action is met.

[0055] Before step S3, the host terminal sends the unloading operation instruction to the vehicle-mounted control terminal according to the loading information of the loader 5 and the pre-set working process; wherein the unloading operation instruction includes the target batcher 31 information of the current material to be unloaded; S3: unloading operation: the loader 5 moves to the corresponding batcher 31 in the stockyard area of the stockyard 4 according to the unloading operation instruction and the layout of the stockyard 4, and then the loader 5 unloads the material to the corresponding batcher 31; Specifically, the working shovel loader drives to the batcher 31 according to the unloading operation instruction, and the vehicle-mounted antenna 9 in the vehicle-mounted device returns the shovel loader positioning information to the host terminal, and the host terminal compares the actual position of the shovel loader with the position parameters of the target batcher 31. If the transported material can be unloaded at the current batcher 31, a prompt signal is sent for unloading operation. If the position of the shovel loader does not match the position of the current batcher 31, it indicates that the transported material cannot be unloaded at the current batcher 31, and the host terminal sends an alarm instruction to the vehicle-mounted control terminal, and the vehicle-mounted control terminal sends an alarm signal to prompt the driver to change the batcher 31 position until the shovel loader positioning information meets the requirements of the target batcher 31, and the unloading operation of the material is completed. If the driver ignores the alarm information and performs incorrect unloading, the vehicle-mounted control terminal will send an alarm signal and return to the control host terminal, and the control terminal will display the error and pause the mixing of the mixer, and then clean the batcher 31 to avoid waste after mixing and reduce the loss of error.

[0056] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
