DETAILED DESCRIPTION

[0016] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1: Figure 1 to Figure 15 As shown, an intelligent mixing station device includes: The concrete task order filling module is used to generate concrete demand tasks for ordering the required concrete and push them. The concrete information in the concrete demand tasks includes project name, construction address, construction unit, construction distance, contact information, sand and gravel grading, concrete strength, pouring method, slump, construction location, planned volume, and planned time. The information platform module is used to generate a production scheduling plan after receiving the concrete demand task pushed by the concrete task order filling module, and obtain the concrete mix ratio plan for push; The production module is used to receive the concrete mix ratio plan and queue up for mix ratio. When the queue time is up, the concrete raw materials are sent to the mixer according to the mix ratio to obtain the concrete required by the concrete demand task; The early warning module is used to provide early warning reminders on the materials and production time of concrete during the production process; Concrete transportation and monitoring module is used for the transportation and monitoring of materials entering the site and the transportation of concrete and its route monitoring.

[0018] The information platform module is also connected to an automatic bill storage and retrieval system, which collects the QR code of the concrete production task order of the integrated information platform in real time. The bills are automatically classified and archived by scanning the QR code, replacing manual sorting of bills and effectively reducing labor costs.

[0019] The concrete transportation and monitoring module is also equipped with a vehicle intelligent queuing module, which is also connected to the vehicle entry and exit. The vehicle intelligent queuing module queues the delivery vehicles required to transport concrete at each construction site according to the production tasks and the time of the production tasks. After observing the queuing time through the mobile phone APP, it waits for the right time to enter the mixing station. Concrete transportation vehicles enter the station using a scale + license plate recognition + display screen + voice prompt device. There is no need to stop, and they can automatically punch in and out. The electronic LED display screen and automatic voice prompts ensure fair and just vehicle scheduling. The key project priority sorting module set in the production module automatically prioritizes the production of key projects to ensure the supply of concrete for key projects, reducing the workload of dispatchers, and greatly improving work efficiency and quality. The concrete transportation and monitoring module is also equipped with a GPS intelligent navigation and positioning system, which can accurately determine the position of concrete transportation vehicles. The location, distribution work point, operation status and driving trajectory are clearly visible; the electronic fence and driving record are integrated to monitor the vehicle in real time and warn of violations to ensure transportation safety, improve transportation efficiency and reduce supply interruptions; the production module is also equipped with a powder intelligent monitoring system, which uses patch sensors, 4G mobile terminals and other technologies to monitor the weight of the remaining material in the silo, the material level, pipe lock and alarm status in real time and upload them to the information platform module, and automatically displays the corresponding silo material status through the human-machine material dynamic display module set in the information platform module, which can intuitively understand the status of each silo, and display the warning level through dynamic color changes (red material level is warning, yellow material level is reminder, green material level is normal status), and then remind to add materials, and can also carry out expected material planning and transportation according to the data, replacing the traditional manual knocking of cans, effectively preventing feed explosion and production interruption; automatically generate analysis reports to provide accurate data support for material management and reduce process management costs.

[0020] The information platform module can be used for concrete raw materials to enter the station after passing the vehicle inspection. After the transport vehicle enters the weighbridge, the driver scans the code on the guidance screen to enter the material information. The system intelligently distributes and displays the guidance information, automatically opens the aggregate silo gate or the powder storage control valve, and the driver self-services to accurately find the silo and unload the materials according to the guidance information. At the same time, the smart center uses the video monitoring system for real-time control to achieve automatic collection and processing of the entire process from automatic vehicle identification, accurate weighing, material distribution, and guided unloading, avoiding human intervention and ensuring data accuracy. The automatic silo access control system set up by the information platform module can only open the gate after the raw materials are inspected and qualified, to prevent the mixing of raw materials in the silo and the use of raw materials before inspection.

[0021] The mixing station actively practices the concept of green environmental protection, creates practical results with intelligence, and strives to create a model of green and low-carbon construction. The mixing station adopts fully enclosed management, and a fully automatic door-type car wash machine is installed at the entrance and exit to ensure that mud does not enter the station and dust does not leave the station; the station is equipped with an online dust monitoring system to monitor various indicators in real time; through the outdoor dust suppression system, the high-pole rotating spray pile is remotely controlled in a timed and cyclic manner to minimize dust; the silo is fully covered with automatic induction spray devices, and dust monitoring exceeds the standard, and spraying is automatically carried out to reduce dust, which greatly improves the production environment and ensures the quality of concrete entities.

[0022] The mixing station of the present invention applies mobile Internet, Internet of Things, cloud computing, big data and other technical means, and fully studies and integrates production control systems, distribution management systems, weighbridge information management systems, vehicle information management systems, monitoring systems, early warning systems, etc., in order to form a seamless integrated information management platform, comprehensively upgrade the interaction mode, working method and management mode of traditional mixing station on-site management, promote the standardization, standardization, intelligence and informatization of mixing station management, help managers break through information communication barriers, and timely and accurately grasp the operation of concrete production and distribution, raw material supply, equipment and personnel, etc., to achieve end-to-end communication, improve work efficiency and reduce production costs.

[0023] The mixing station first collected information and data based on the characteristics of the concrete mixing station on the construction site; carefully analyzed the concrete supply situation of the Xiongxin High-speed Railway Mixing Station; classified and summarized the difficulties faced by the mixing station in concrete production, mixing, transportation, material management, roads, etc., and finally formed a set of overall solutions to resolve the contradiction between supply and demand between concrete mixing station production and on-site construction, scientifically and rationally allocate concrete transport vehicles, accurately grasp the operation dynamics of vehicles on construction access roads and construction sites, and grasp the use of concrete raw materials, to ensure high-quality and efficient delivery of concrete to the construction site.

[0024] The mixing station is equipped with an information-based dispatching and command center to fully realize information management. The information-based production and distribution control technology of the concrete mixing station is based on the traditional concrete production and distribution model, with the information management system as the center, and fully studies and integrates the production control system, the weighbridge information management system, the vehicle information management system (monitoring, queuing, fuel consumption), the monitoring system, the early warning system, etc., in order to form a seamless integrated information management platform.

[0025] Information management of the whole process: 1) Realization of information-based mobile office. The corresponding functions of the APP are tailored for the mixing station at the mountain construction site, and users can download and install it through the mobile application store. From concrete application, production, transportation, to real-time monitoring of raw materials, fuel consumption, and vehicles, etc., it can all be completed on the mobile phone, truly realizing mobile office, responding to complex production scenes at any time, and improving work efficiency.

[0026] 2) Quick and orderly ordering via mobile APP. On-site construction personnel directly create a concrete application form through the mobile APP (similar to ordering food in a restaurant), which is transmitted to the computer of the dispatching command center of the mixing station and the mobile APP of relevant personnel through the network. The laboratory issues a "Concrete Construction Ingredients Notice" and pushes it to the industrial computer of the mixing plant to produce concrete.

[0027] Concrete production pre-scheduling system: According to the characteristics of concrete construction on the construction site, the concrete production pre-scheduling system can be customized to achieve priority supply for key construction sites. The system can automatically identify the "production task list" of concrete for important parts such as "jetting, underwater piles", and prioritize it to the "pending production status" without waiting in line (similar to bank VIP customers), which not only improves work efficiency, but also reduces the probability of errors, and supports real-time viewing of production progress to ensure efficient operation of concrete from planning, production, distribution and other links.

[0028] The whole process monitoring module of transport vehicles: Rapid and orderly deployment of vehicles: Using ETC vehicle identification technology and LED queuing system, transport vehicles can automatically queue and call numbers (similar to the queuing and calling system of banks), which greatly improves work efficiency and ensures orderly production; Dispatchers at the mixing station can easily deploy vehicles through the computer of the smart center or mobile phone APP. Real-time control of vehicle status: All vehicles have been installed with GPS terminals to monitor the real-time location, operation status, distribution work points, driving speed, operation trajectory, etc. of transport vehicles at any time, and integrate driving recorders to monitor whether the vehicle is speeding, identify the road conditions, and prevent driving safety risks; driving trajectories can also be replayed through GPS maps; real-time display of the operation dynamics, unloading, loading, driving, etc. of each transport vehicle, easy dispatch; set up smart ticket cabinets: The smart terminal of the "Smart Dispatching and Logistics System" designed for mixing stations has self-service ticket return and automatic sorting functions. The driver can operate it by himself throughout the process, which completely liberates manual ticket collection and sorting, and reduces the workload of statisticians.

[0029] The material human-machine interaction module allows for a clear view of the raw material inventory. Each powder tank of the mixer is equipped with a patch sensor to automatically weigh the material in the powder tank and transmit it to the material display screen. The management personnel can determine the feeding time and quantity based on the concrete demand plan of the construction site, so that production will not be interrupted due to "lack of materials" and the smooth progress of concrete construction on the construction site is guaranteed. The intelligent floor scale system is integrated with the information management system. Any area within the scope of authority can be directly connected to the network for weighing, and the quality of raw materials and vehicle license plates can be captured on site, and uploaded to the network server for storage in real time to analyze the quality and quantity of raw materials, realize traceability, and eliminate management loopholes.

[0030] The information platform module is also equipped with a production progress interaction module, which can control the production progress in real time. 1) Volume query module in the production progress interaction module: On-site personnel can query the production volume statistics table and production volume daily report through computers or mobile phone APP, easily grasp the real-time volume of each work point, and provide decision-making basis for site managers. In the past, it was necessary to query the computer through the dispatcher or statistician, and it was difficult to query the real-time volume; 2) Progress query module in the production progress interaction module: Managers at all levels can query the planned volume and completed volume of concrete at each work point through computers or mobile phone APP, understand the completion progress percentage of each concrete demand part, control the concrete construction progress in real time, and provide decision-making basis for the next step of construction production planning.

[0031] The road navigation map drawing module set in the whole process monitoring module of transport vehicles: the concrete transportation roads and construction sites of the construction site mixing station are basically newly built and not displayed on the existing GPS map, which has caused great difficulties in the dispatching and monitoring of concrete mixing transportation vehicles. In order to solve this problem, the system has specially added a map drawing function, that is, accurately drawing the location of the mixing station, the construction site road, the construction site, etc. on the existing GPS map, so that the concrete production, transportation, and construction are fully controllable.

[0032] Furthermore, the above-mentioned mixer is installed in the mixing room, and the discharge port of the mixer extends into the material receiving port arranged on the front side of the mixing room. The feed port of the mixer is connected to the cement conveying pipe, the sand and gravel conveying device, the additive conveying pipe and the water pipe. The sand and gravel input end of the sand and gravel conveying device is provided with a weighing hopper, and the weighing hopper is arranged in the sand and gravel grading workshop arranged on the rear side of the mixing room. The cement conveying pipe and the additive conveying pipe are connected to the cement storage bin and the additive tank, and the water pipe is connected to the water pump.

[0033] Among them, Figure 2-6 As shown, a crushed stone bin 101 and a river sand bin 102 are arranged side by side at the rear side of the sand and gravel grading workshop. There are multiple crushed stone bins 101 for stacking crushed stones of different particle size ranges, and there are multiple river sand bins 102 for stacking river sand. The multiple crushed stone bins 101 and the multiple river sand bins 102 as well as the crushed stone bins 101 and the river sand bins 102 are isolated by partition walls 103. Heating coils 105 are arranged in the bottom surfaces of the crushed stone bins 101 and the river sand bins 102. The heating coils installed on the bottom surfaces can heat and insulate the stacked sand and gravel, heat them to a temperature range that meets the requirements of concrete, and then add them to the mixing equipment to mix them into concrete, thereby improving the performance of the concrete at low temperatures and avoiding a significant impact on the performance of the concrete due to excessively low temperatures.

[0034] In order to improve the safety of the heating coil during use and prevent trucks from entering and crushing the heating coil, a coarse steel mesh layer 128 and a fine steel mesh layer 129 are arranged on the upper and lower sides of the heating coil 105 respectively. The heating coil 105, the coarse steel mesh layer 128 and the fine steel mesh layer 129 are placed in the concrete on the bottom surface. The coarse steel mesh layer 28 and the fine steel mesh layer 129 can better balance the force during use of the heating coil, distribute the force evenly, and avoid local damage caused by stress concentration. A support bar 131 is arranged between the fine steel mesh layer 129 and the foundation 130 to facilitate the filling of concrete onto the foundation 130. The concrete poured for the heating coil 105 is a layer of concrete poured later, forming an integrated structure with the foundation 130.

[0035] After the sand and gravel are heated, in order to facilitate temperature measurement, temperature sensors 106 are arranged above the gravel bin 101 and the river sand bin 102. The temperature sensor 106 adopts a thermocouple. The temperature sensor 106 is placed in the heat conduction pipe 7. The lower end of the heat conduction pipe 107 is provided with a spike portion 108. The upper end of the heat conduction pipe 107 is fixedly connected to the fixed push plate 8. The fixed push plate 108 is connected to the L-shaped sliding plate 111 through two guide rods 109 and a linear bearing 110. The two guide rods 109 pass through the sliding plate 111. The two rear ends are fixedly connected with linkage plates 112, a connecting ear 113 is provided on the front side of the fixed push plate 108, the connecting ear 113 is fixedly connected to the cylinder rod of the cylinder 114, the cylinder seat of the fixed push plate 108 is fixedly connected to the sliding plate 111, the sliding plate 111 is connected to the slider 116 of the vertical linear module 115, the back of the vertical linear module 115 is fixedly connected to the transition plate 116, the transition plate 116 is fixedly connected to the slider 2 of the horizontal linear moving module 117, and the horizontal linear moving module 117 is fixedly connected to the slider 116 of the horizontal linear moving module 117. The crossbeam 118 is fixedly connected to the crossbeam 118 at both ends and is connected to the track 120 above the two partition walls 103 through the front and rear walking mechanism 119. The two partition walls 103 are two partition walls spanning the outermost sides of multiple gravel bins 101 or the outermost sides of multiple river sand bins 102. By controlling the temperature sensor, multiple points are measured in each bin where sand and gravel are piled, so as to realize the measurement of different positions and different depths, which is conducive to taking the average value of multiple values ​​of each sand and gravel bin as the evaluation value, and the measurement is more accurate. The linear module moves, and the moving distance is accurate and stable. The insertion is guided by the spike part to avoid damage to the heat pipe and improve the service life of the heat pipe. The temperature sensor of the thermocouple is protected by the heat pipe, which can also improve the service life of the thermocouple and avoid the problem of damage caused by direct insertion of sand and gravel. The fixed push plate supported by the double guide rod is pushed by the cylinder, and the thermocouple moves to realize smooth insertion. The linear module is also convenient for the cylinder to lift, so as to avoid collision with the partition wall in the two sand and gravel bins due to being too low.

[0036] In order to avoid waste of water resources, the heating coils 105 arranged under each gravel bin 101 and each river sand bin 102 are connected in parallel to the main pipe 121. The main pipe 121 is connected to the water pump 122 and the hot water tank 123 through a circulation pipeline. The hot water tank 123 is equipped with a heating device. The water resources are circulated back and forth through circulation to avoid waste of water resources and energy, reduce costs, and independently heat. The main pipe 121 includes an inlet main pipe and an outlet main pipe. The heating coils of each bin are connected to the main pipe 121 to realize independent circulation connection of the single bin. In order to facilitate independent control, electric valves are installed on the inlet main pipe and the outlet main pipe.

[0037] In order to simplify the supporting structure and stabilize the support, the track 120 is fixedly connected to the partition wall 125 by two channel steel columns 124. The grooves of the two channel steel columns 124 are arranged relatively to each other, and a heightening baffle 125 is detachably installed between the two channel steel columns 124. The use of two channel steel columns can greatly improve the supporting stability of the track, and the channel steel columns can realize the heightening operation, which is easy and convenient. The two ends of the heightening baffle 125 fit tightly in the grooves, and the joints of two adjacent heightening baffles are respectively provided with slots and protrusions to improve the sealing and support stability.

[0038] In order to avoid adding sand and gravel incorrectly, gate machines 126 are set on the discharge sides of the crushed stone bin 101 and the river sand bin 102. When sand and gravel from the corresponding sand and gravel bin are needed, the gate machines are opened and a forklift enters to transfer materials to avoid promoting the material site and causing incorrect sand and gravel grading of concrete.

[0039] In order to facilitate real-time and approximate assessment of the amount of sand and gravel stored, length scales and multiple height scales are set on both sides of the partition wall 103. The multiple height scales are evenly arranged along the front and rear directions. According to the height scale and the length scale, and the width of the sand and gravel bin is known, the specific cubic meter of the sand and gravel can be roughly assessed.

[0040] In order to facilitate understanding of the basic conditions of the sand and gravel bin, each crushed stone bin 101 and river sand bin 102 is equipped with a display screen 127, which is installed on the partition wall 103 and is used to display aggregate type, particle size, remaining sand and gravel amount and temperature.

[0041] Among them, Figure 7As shown, the water pipe is connected to the heating device of the mixing station. The heating device of the mixing station includes an air energy heat pump 201 and a hot water tank 202. The air energy heat pump 201 is provided with a cold water pipe 203, a hot water pipe 204 and a circulating water pump 205.

The unit can be placed on the roof or the ground at will, does not occupy the effective use area of ​​the building, and is very convenient to construct and install.

[0042] The working principle of air energy heat pump is to use the heat pump principle to consume part of the electric energy to obtain heat from the surrounding environment, transport it to the condenser through the compressor, and release it to the water in the water tank to heat it. Its energy efficiency is more than 3 times higher than that of traditional electric water heaters. It is a new type of high-efficiency, energy-saving and environmentally friendly hot water product. When the unit is running in summer, it uses refrigeration cycle to cool the water (coolant), and in winter, it uses heat pump cycle to heat the water. The cold (hot) water is pumped to various predetermined places, thereby achieving the purpose of transporting cold (heat).

[0043] A heating coil 211 is installed on the bottom surface of the silo 241 to heat and insulate the stacked sand and gravel. The sand and gravel are heated to a temperature range that meets the requirements of concrete and then added to the mixing equipment to be mixed into concrete, thereby improving the performance of the concrete at low temperatures and avoiding significant impact on the performance of the concrete due to excessively low temperatures.

[0044] In order to reduce the possibility of damage to the pipeline interface caused by long-term vibration of the circulating water pump, the circulating water pump 205 is connected to the ground through a shock-absorbing mechanism, which can reduce the vibration of the circulating water pump.

[0045] Furthermore, a water tank temperature sensor 214 is installed in the hot water tank 202 , and a water supply pipe 215 and a water level sensor 216 are installed on the top of the hot water tank 202 .
