[0034] As Figures 1-5 shown, the embodiments of this application provide a raw material quality control system for a self-built mixing station in a desert wind power project. The raw material quality control system for the self-built mixing station in the desert wind power project includes a quality control system, a comprehensive data collector 1, a 4G Internet of Things gateway 2, a platform server 3, a control terminal, and a mixing tank 6. Among them, the quality control system includes a water temperature control unit, a cement temperature control unit, a sand temperature and humidity control unit, and an aggregate particle size identification and processing unit; the comprehensive data collector 1 is data-connected to the quality control system for data collection and data display; the 4G Internet of Things gateway 2 is data-connected to the comprehensive data collector 1 and the platform server 3. The 4G Internet of Things gateway 2 has a display screen, and the 4G Internet of Things gateway 2 can transmit the data information collected by the comprehensive data collector 1 to the platform server 3; the control terminal is data-connected to the platform server 3 and can control the quality control system. The control terminal includes a PC terminal 4 and a mobile phone terminal 5; the mixing tank 6 is used for mixing raw materials.

[0035] The comprehensive data collector 1 has the functions of wired transmission collection and wireless LAN transmission fixed surrounding collection. Wireless devices within its coverage range can be connected to the device for real-time data collection. At the same time, the comprehensive data collector 1 has a display screen that can display the collected data content in real time. After the comprehensive data collector 1 is connected to the 4G Internet of Things gateway 2, the collected data can be transmitted to the cloud platform through the 4G network.

[0036] The raw material quality control system of the self-built mixing station of the desert wind power project can control the water temperature, cement temperature, sand temperature and humidity, and aggregate particle size entering the mixing tank 6 respectively through the water temperature control unit, cement temperature control unit, sand temperature and humidity control unit, and aggregate particle size identification and processing unit, thereby improving the quality of various raw materials for concrete, achieving more standardized temperature, slump, and mix ratio indicators of the project's self-mixed concrete, and providing a reference system solution for projects of the same type.

[0037] like Figure 3 As shown, in a specific embodiment, the water temperature control unit includes a water tank 7, a refrigerator 8, an ice cube delivery device 9 and a thermometer 10; the water tank 7 is connected to the mixing tank 6 through a pipeline provided with a valve 11, the thermometer 10 is arranged on a side of the pipeline close to the mixing tank 6, the thermometer 10 is data-connected to the comprehensive data acquisition instrument 1, and the refrigerator 8 and the ice cube delivery device 9 are used to reduce the water temperature in the water tank 7. The water temperature control unit can further strengthen the monitoring of the water temperature before entering the warehouse.

[0038] The water temperature control unit has a first preset temperature when working. When the monitoring value of the thermometer 10 is less than the first preset temperature, the valve 11 opens; when the monitoring value of the thermometer 10 is greater than or equal to the first preset temperature, at least one of the refrigerator 8 and the ice cube delivery device 9 works to lower the water temperature in the water tank 7.

[0039] like Figures 3-4 As shown, the thermometer 10 is linked with the controller of the valve 11, and the internal opening and closing rules are set. The opening and closing conditions of the valve 11 are determined by the water temperature. The thermometer 10 is connected to the comprehensive data acquisition instrument 1 through the data acquisition line to check the water temperature data entering the warehouse locally. After the data is collected and processed, the water temperature is uploaded through the 4G Internet of Things gateway 2, so that the management personnel can determine whether the water temperature can be brought to the standard by the refrigerator 8 when there is a mixing demand. If not, they can add ice as an emergency measure to maintain the normal pouring progress of the project.

[0040] like Figures 1-2As shown, in a specific embodiment, the cement temperature control unit includes a fixed thermometer 12 and a handheld thermometer 13. The fixed thermometer 12 is data-connected to the integrated data acquisition instrument 1, and the handheld thermometer 13 is data-connected to the integrated data acquisition instrument 1 or the platform server 3. The fixed thermometer 12 is arranged inside the cement silo 14 to monitor the temperature change of the cement inside the silo. The handheld thermometer 13 is used to monitor the temperature of the cement in the cement transport vehicle 15 before it enters the cement silo 14 to determine whether the temperature of the externally purchased cement meets the storage temperature after it arrives at the site.

[0041] Before the cement enters the silo but has not entered the bin, set a temperature detection point for the cement transport vehicle 15. When the cement transport vehicle 15 enters the site, drive it to the detection point, and a professional management personnel uses the handheld thermometer 13 to detect the current temperature of the cement. Compare the temperature requirement for the cement to enter the silo. If the requirement is met, then store it in the silo. If the requirement is not met, it should be continuously static on the cement transport vehicle 15 until the temperature drops to the requirement for entering the silo, and then arrange for storage in the silo. As Figure 2 As shown, the handheld thermometer 13 is built-in with a 4G communication module and can be directly wirelessly uploaded to the cloud through an IoT card for data collection, storage, and analysis of the cement arrival temperature, which is one of the key control elements of the mixing plant.

[0042] When the cement is stored in the cement silo 14, measure the temperature of the cement in the silo through the fixed thermometer 12. Since the temperatures of different layers of cement will be different, the fixed thermometer 12 is installed near the cement inlet and outlet pipe of the silo to ensure that the temperature of the cement used for the latest mixing meets the local specifications and standards. When the requirement is not met, concrete should be poured back into the silo and left static, and the concrete pouring plan should be postponed. Choose to carry out the mixing work after the temperature drops at night. The fixed thermometer 12 is connected to the integrated data acquisition instrument 1 through a data acquisition line for local data viewing. At the same time, after the data is collected and processed, the temperature of the cement in the cement silo 14 is collected and analyzed in real time through the 4G IoT gateway 2 to provide reference data and opinions for the management personnel.

[0043] As Figures 1-2 As shown, in a specific embodiment, the sand temperature and humidity control unit includes multiple temperature and humidity detectors 16. The temperature and humidity detectors 16 are data-connected to the integrated data acquisition instrument 1, and the multiple temperature and humidity detectors 16 are arranged in at least two layers inside the sand pile 17 in the material yard. The temperature and humidity detectors 16 are used for detecting the temperature and humidity of the sand. Through actual investigation, since the project environment belongs to a long-term dry environment, the moisture content difference between the surface layer and the lower layers of the sand is relatively large, and its temperature difference is also relatively obvious. Therefore, it is installed in a layered and distributed manner in the material yard to eliminate the data misleading caused by personalized detection. Because the current equipment for measuring the moisture content of sand basically belongs to laboratory equipment, it is considered to convert to its humidity detection to replace its moisture content index.

[0044] After industry experts learned about the actual situation of desert raw material sand, it was proposed that in the desert environment, since river sand is used, its temperature and humidity are significantly affected by the environmental climate. For example, if the temperature and humidity of the sand are too dry or wet, errors are likely to occur in the conventional concrete mix ratio, resulting in the quality of the concrete being affected. The self-built mixing station has a large sand pile and is placed in a semi-open environment, and there are also significant differences in the temperature and humidity inside and outside the sand pile 17. As Figure 1 shown, the sand pile 17 is evenly distributed in different heights and around the perimeter. Through the data acquisition line, it is connected to the comprehensive data acquisition instrument 1 for local data viewing. At the same time, after the data is collected and processed, the data of each temperature and humidity detector is transmitted to the cloud for application through the 4G Internet of Things gateway 2 to determine the currently most suitable sand layer. Thus, when the filler is filling, the most suitable sand is used for the current stage of mixing, and after use, it is covered and stored statically to prepare for the next use.

[0045] As Figure 1 and Figure 5 shown, in a specific embodiment, the aggregate particle size identification and processing unit includes a particle size camera 18. The particle size camera 18 includes an algorithm module capable of identifying the aggregate particle size. The particle size camera 18 is data-connected to the comprehensive data acquisition instrument 1. The particle size camera 18 is installed beside the belt conveyor where the aggregate is transported to the mixing tank 6, and is used to regularly capture the spread pictures of the aggregate before feeding. Through the internal algorithm module for calculation and identification analysis, it discriminates whether there are aggregate particle sizes exceeding the specification or standard. The aggregate particle size identification and processing unit also includes a secondary screening device, which is used for secondary screening and processing of the aggregates whose particle sizes exceed the specification or standard.

[0046] Currently, domestic new mixing systems have realized the application of aggregate particle size identification equipment, but its equipment price is expensive and it is not suitable for old mixing systems. Therefore, its defects have been transformed and applied. As Figure 5 shown, the finished aggregate enters the belt conveyor after the first screening. However, due to the relatively rough first screening, there are still omissions entering the belt conveyor. Therefore, a particle size camera 18 is installed at the belt conveyor where the aggregate exits the screening area. By checking the aggregate before it enters the bin, if there are aggregates that do not meet the requirements, they are timely captured and marked, and transmitted to the comprehensive data acquisition instrument 1 through wire transmission. The management personnel can observe the situation of the aggregate through the real-time video of the comprehensive data acquisition instrument 1. If there are any non-conformities, the operation plan of the belt conveyor is adjusted in time, and the aggregate is transported to the crushing workshop for secondary crushing. After crushing, it is fed and identified again, and this cycle is repeated to ensure that the particle size of the aggregate meets the local specification standards before entering the bin for mixing.

[0047] As Figure 2As shown, in addition to locally integrating the recognition data and the images onto the display screen of the comprehensive data collector 1 for viewing, the particle size camera 18 can also transmit the recognition events and videos to the cloud through the 4G IoT gateway 2 and distribute them to the project material procurement personnel. Any unsatisfactory situations are fed back to the aggregate suppliers for rectification, thereby improving the quality control of the project's aggregate particle size.

[0048] As Figure 6 shown, through targeted monitoring and control data collection of all the key quality elements of the raw materials, two modes of local application supervision and online data application are adopted to achieve the quality control of the concrete raw materials, and finally a research-based result is formed to establish a standardized quality control system for the concrete raw materials in the batching plant.

[0049] In addition, the above-mentioned various types of collection devices integrate the data collected by each of them into the comprehensive data collector 1 through wired or wireless transmission for the next step of data upload application and linkage application. To carry out the next-step application of the monitoring data and realize its monitoring value, application control measures are taken for the data collected by each device, mainly including:

[0050] The first link is the control of the water temperature entering the bin. After the comprehensive data collector 1 collects the water temperature before entering the bin, data discrimination is performed. If the water temperature meets the normal water supply, if it does not meet, the valve 11 will be automatically closed, reminding the management personnel to increase the refrigeration time and power. When the maximum code rate of the refrigerator 8 cannot control the water temperature entering the bin to the appropriate temperature, the management personnel will be actively reminded to add ice in time for rapid cooling.

[0051] In the second link, after the distributed detection of the surface and internal temperature and humidity of the sand, information can be effectively fed back to the loading personnel through the display screen of the data collector or the notification method of the background mobile app software, reminding the loading personnel to preferentially select suitable sand for production, effectively avoiding the deviation of the slump of the concrete produced according to the conventional mix ratio due to the inconsistent moisture content of the surface sand and the bottom sand.

[0052] In the third link, the temperature of the cement can be collected by the handheld thermometer 13 before it is stored at the site during transportation. When the management personnel measure that it does not meet the storage temperature, the background should automatically judge and calculate the approximate time required for cooling, and timely remind the management personnel to measure again. When it meets the requirements, arrange for it to be stored in the tank;

[0053] In the fourth link, when there is a pouring plan for the project, the temperature of the cement in the cement silo 14 should be concerned in advance. When it does not meet the requirements, the silos should be emptied and left standing in advance, and the pouring time period should be adjusted to the evening. When the temperature of the cement entering the bin meets the requirements, the detection information should be automatically sent to the relevant management personnel to start the mixing work;

[0054] In the fifth step, by identifying and detecting the aggregate particle size during the feeding process, the particle sizes that do not meet the requirements are marked using the image analysis function. Then, the screening system is linked again to re-crush the non-conforming aggregates and convey them back to the mixing tank in the production workshop.

[0055] By combining the monitoring system part and the control system part, a raw material temperature and quality control system for the project's concrete mixing station is formed.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
