[0024] Embodiment 1 like Figure 1-6 As shown, the present invention proposes a smart concrete management and control system based on the Internet of Things technology, including a purchasing end for publishing purchasing information; a mixing station end, including a mixing station production management system, for receiving the purchasing information released by the purchasing end, and producing concrete according to the purchasing information, while realizing the data management of the task order, test ratio, raw material purchase and sale, raw material weighing, and raw material testing within the mixing station; a driver end, for transporting the concrete sent by the mixing station end to the construction site where the purchasing end is located, and locating the location in real time, and after arriving, presenting a QR code for electronic scanning and signing or the purchasing end signing by itself. The signing unit includes a receiving management module, a quality management module, a settlement module, and a weighbridge management module; a quality management module, for checking the quality of concrete and providing quality feedback; a collection end, for receiving the order information sent by the purchasing end, automatically transmitting it to the mixing station production management system, and collecting the production and delivery data of the mixing station, and transmitting it to the purchasing end and the driver end.

[0025] The receiving management module is used to receive concrete delivered by the driver, record vehicle information, and estimate the arrival time. It measures the concrete loaded on the vehicle through the weighbridge management module, automatically compares the data of the shipping volume and the weighed volume, forms a profit and loss analysis, and generates an electronic receipt, which includes vehicle information, receipt time, concrete grade, and receipt volume.

[0026] In this embodiment, the customer logs in to the purchasing end and can view the location of the attached mixing station end, as well as the information of the mixing station end. The customer issues a purchase order through the purchasing end. After receiving the information, the mixing station end verifies the purchase order information with the customer. After the verification is completed, the order can be allocated according to the customer's needs or the purchase order information can be issued according to the mixing station end specified by the customer. The type of concrete that can be produced, the surplus, and the available transportation vehicle information are indicated at the mixing station end. The mixing station end allocates the order to the delivery unit according to the purchase order information. If one mixing station end cannot meet the order requirements, and the purchase order is split through the mixing station end, the order can be allocated to multiple delivery units to meet the needs of the purchasing end.

[0027] The mixing station produces or unloads materials according to the purchase order and loads them onto the truck. After loading, the vehicle information is recorded and matched with the purchase order. By identifying the vehicle information, the type, weight, delivery address, and estimated delivery time of the concrete loaded on the vehicle can be determined. The driver drives the vehicle to the construction site based on the above information. After the construction site scans the vehicle information, the concrete can be signed for and used.

[0028] The weighbridge management module uses license plate recognition, automatic weighing and data transmission technology to realize automatic identification, weighing and data recording of transport vehicles, and transmits data to the mixing station in real time, eliminating manual operation links, improving weighing efficiency and accuracy, and reducing the possibility of human errors and cheating.

[0029] After the raw materials enter the mixing station, they are tested and weighed. After weighing, the raw materials are unloaded and enter the production link. According to the purchasing information from the purchasing end, after the mixing station receives the order, it arranges production and arranges the driver to schedule shifts. Concrete is produced according to the requirements of the purchasing end, and a dispatch instruction is issued to the driver to drive to the production line to receive the produced concrete. When the vehicle stops under the discharge port, the mixing equipment is started to discharge the material and concrete is injected into the vehicle. The vehicle is weighed when unloading the material, so as to determine how much concrete the vehicle carries.

[0030] After the vehicle is loaded, the driver transports the concrete according to the order information and delivers the concrete to the construction site on the purchasing end. The driver can choose to click on the information on the mobile phone, "Delivered", "Transfer to Pouring" and "Completed", switch the current status, and facilitate the mixing station to allocate vehicles. After the vehicle enters the construction site, it is weighed and the vehicle information is recorded. The weight and type of the concrete transported this time can be determined based on the vehicle information. At this time, the driver clicks "Delivered" and starts unloading the concrete. After unloading is completed, click "Completed". At this time, the purchasing end clicks the "Sign for" option, which means that the order has been signed for. At this time, the empty vehicle is weighed again to determine how many tons of concrete have been used, which can facilitate measurement. The driver drives the vehicle back and chooses to queue up to continue transportation or end the order and go off work based on the order information. If you choose to queue up to continue transportation, you will queue up to move to the production line to receive concrete.

[0031] By positioning the vehicle driven by the driver, it is possible to determine whether the vehicle has arrived at the construction site. Only after it has arrived at the purchaser's site can you click "Arrived" and determine whether to transfer pouring by observing the rotation of the vehicle storage tank. When the storage tank is reversed, it is determined to be transfer pouring. By installing multiple cameras on the vehicle, the driving status of the vehicle can be monitored.
