Description

Technical Field

[0001] The invention relates to the field of automation technology, in particular to a vehicle-mounted system capable of remotely and quantitatively adding concrete admixtures. Background Art

[0002] In large-scale construction projects, the transportation of commercial concrete by trucks can meet the demand for a large amount of concrete, improve construction efficiency and reduce costs. In urban infrastructure construction, the high quality and efficient transportation characteristics of commercial concrete make it widely used in the construction of roads, bridges, etc. Since commercial concrete can reduce environmental pollution, it is more popular in projects with high environmental protection requirements. Commercial concrete transported by trucks can load more concrete at one time, reducing the number of transportations, thereby improving transportation efficiency. Compared with other modes of transportation, the transportation cost of commercial concrete transported by trucks is relatively low, which helps to reduce the overall project cost. Commercial concrete uses professional production processes and strict quality control to ensure that the quality of concrete is stable and reliable, and it has high strength. The use of commercial concrete can significantly reduce the waste of materials such as sand, gravel and cement, and reduce construction costs. Commercial concrete has a fast construction speed and a high degree of mechanization, which can speed up the construction progress and reduce the turnover rental costs of equipment, pipe racks and formworks. The use of commercial concrete can save construction land, reduce resource waste, improve working conditions, and reduce environmental pollution. The use of commercial concrete can improve the image of the owner and the construction company and improve the level of urbanization.

[0003] However, traditional commercial concrete transportation has the following disadvantages: During the transportation of commercial concrete, the unloading of concrete may be delayed or impossible due to various reasons, such as traffic accidents, on-site equipment failures, temporary adjustments to the construction plan at the site, etc. The concrete is mixed for a long time in the concrete mixer truck, and its properties change greatly. At this time, it is necessary to adjust the concrete properties by adding concrete admixtures. This is a common problem in the current construction industry. Most commercial concrete mixing stations will have one or more front-end quality technicians who carry concrete admixtures and climb to the rear of the concrete mixer truck to add them to adjust the concrete properties to achieve suitable construction conditions. This operation has great safety hazards, and the amount of addition is not easy to quantify, and it is particularly dependent on the experience and technical level of the technicians.

[0024] Cloud server remote control method: Assume that the concrete mixer truck shown is loaded with concrete. Due to external factors, it cannot be unloaded in time. The slump of the concrete inside the tank body is reduced due to long-term mixing, and it is not suitable for construction. At this time, the technician uses the terminal including a computer, a touch screen, and a mobile phone for remote control, selects the type of concrete admixture to be added, enters the amount of concrete admixture to be added, and clicks to start adding; at this time, the cloud server 201 transmits the data from the remote communication module 202 to the main processing controller 203, and the main processing controller 203 immediately starts the control process: Open the hardware part 10 The electric valve 104 is turned on, the self-priming pump 105 is started, and the data fed back by the flow meter 107 is read in real time. When the spraying amount fed back by the flow meter 107 is equal to the input addition amount, the self-priming pump 105 is stopped immediately, and then the electric valve 104 is turned off; after all operations are completed, the cloud server 201 will generate and automatically save a set of data, which includes the operation time, spraying type, spraying amount, operation vehicle, and operator key information; the advantage of the cloud server remote control method is that one technician remotely controls multiple vehicle-mounted devices, saving manpower, and generating relevant operation data groups, while also strengthening the coordination and management function of the overall transportation vehicle; Local wireless control mode, assuming that the concrete mixer truck shown is loaded with concrete, and there is no network signal at the location of the concrete mixer truck at this time, and the cloud server remote control cannot be performed. Due to external factors, the material cannot be unloaded in time. The slump of the concrete inside the tank body is reduced due to long-term mixing, and it is not suitable for construction. At this time, the technicians near the vehicle perform the concrete admixture addition operation through the local wireless remote control 205.

Click to start adding, and the data will be transmitted to the main processing controller 203 through the local wireless module 204, and then the addition of concrete admixture is completed according to the set program. After all operations are completed , a set of data will also be generated and saved in the memory card inside the main processing controller 203. The data includes operation time, spraying type, spraying amount, operating vehicle, and operator key information. When waiting for the vehicle to drive to an area with network coverage, the main processing controller 203 will automatically synchronize the generated data from the remote communication module 202 to the cloud server 201. The advantage of the local wireless control method is that the remote control can be used to add materials even in areas without network coverage. There is no need for technicians to carry additive barrels and repeatedly climb the escalator at the rear of the vehicle. A related operation data group is also generated, which greatly reduces the operation risk. At the same time, the on-site admixture addition amount that could not be counted before can be correctly counted, providing effective data support for concrete quality management, problem tracing, and cost management.
