[0002] With the development of the power generation industry, the demand for fuel for power generation has gradually increased. When purchasing fuel materials, the quality of the purchased fuel and the accuracy of the measurement data have a great impact on the cost control and benefit control of the enterprise. Therefore, the enterprise has designed a precise and scientific control of fuel procurement to effectively prevent fraud and other situations.

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish different objects, rather than to limit a specific order. The following embodiments of the present invention can be implemented separately, or in combination with each other, and the embodiments of the present invention do not impose specific limitations on this.

[0025] Figure 1 The present invention provides a flowchart of a method for managing the purchase of materials.

[0026] like Figure 1 As shown, the management method of purchased materials specifically includes the following steps:

[0027] S101, in response to identifying the identity of a target transport vehicle in a sampling area, controlling a sampling machine to identify a loading area of ​​the target transport vehicle.

[0028] Specifically, the target transport vehicle will deliver the purchased materials, such as fuel, to the factory for storage. After the target transport vehicle enters the sampling area of ​​the factory, the driver uses the card made by himself at the factory gate to swipe the card at the self-service terminal in the sampling area, so that the self-service terminal can obtain the identity of the target transport vehicle. Among them, one target transport vehicle uniquely corresponds to one card, and the card carries the identity of the target transport vehicle, the type of materials, etc.

[0029] After the self-service terminal obtains the identity of the target transport vehicle, it transmits it to the main control unit. The main control unit verifies the identity using the pre-stored material procurement information, and sends a sampling instruction to the sampling machine after the verification is passed, so that the sampling machine can identify the loading area of ​​the target transport vehicle based on the procurement instruction and start sampling.

[0030] S102, randomly generating a preset number of detection sampling positions based on the identified loading area, and controlling the sampling machine to sample the materials in the loading area based on the detection sampling positions.

[0031] Specifically, after the sampling machine identifies the loading area of ​​the target transport vehicle, it randomly generates the location coordinates of a preset number of detection sampling positions based on the loading area. The multiple detection sampling positions generated need to be spaced apart by a set distance to prevent cheating such as repeated sampling in the same area or no sampling in a certain area, which would result in low accuracy and security of the warehousing inspection data.

[0032] S103, assigning a sample code to each collected material sample, and sending the material sample to a testing area for testing.

[0033] Specifically, after sampling at each detection sampling position, the general control unit will assign a sample code to each material sample. The sample code can be set to a six-digit code as needed, or it can be any symbol such as a QR code that can mark the material sample. The coded material sample is then sent to the detection area for detection.

[0034] By encoding the material samples and sending them into the testing area, the testing area can only see the codes of the material samples and cannot know which target transport vehicle the tested material samples belong to. This further avoids the occurrence of cheating and improves the accuracy and security of the warehousing inspection data.

[0035] S104, in response to identifying the material sample sampling completion signal, prompting the target transport vehicle to go to the truck scale.

[0036] Specifically, after the sampling machine completes sampling of the materials, it will directly prompt the target transport vehicle to go to the truck scale for weighing. The prompting methods include but are not limited to screen text prompts, voice prompts, etc.

[0037] The present invention automatically identifies the target transport vehicle arriving at the sampling area, controls the sampling machine to automatically generate a detection sampling position and take samples after successful identification, and encodes the material samples and sends them to the detection area, thereby solving the technical problems of low warehousing efficiency of purchased materials, low accuracy and security of warehousing inspection data, and high labor costs, and achieves the technical effects of improving the warehousing efficiency of materials, improving the accuracy and security of warehousing inspection data, and reducing labor costs.

[0038] On the basis of the above technical solutions, Figure 2 FIG. 1 is a flow chart of another method for managing the purchase of materials provided by the present invention. Figure 2 As shown, in S104, after prompting the target transport vehicle to go to the truck scale, the management method further includes:

[0039] S201, in response to identifying the identity of a target transport vehicle at a truck scale, controlling the weighing gate to lift so that the target transport vehicle can be weighed.

[0040] Specifically, after the target transport vehicle completes sampling, it drives to the truck scale based on the prompt. The identity recognition module of the truck scale can automatically obtain the identity of the target transport vehicle and send the identity to the main control unit. The identity can be the license plate number of the target transport vehicle, which has been entered into the system when the target transport vehicle makes a self-service card before entering the factory area. After the main control unit confirms the identity, it sends a weighing instruction to the truck scale. The truck scale controls the lifting of the weighing gate based on the opening instruction, so that the target transport vehicle can be weighed on the scale.

[0041] S202, in response to identifying the presence of a target transport vehicle on the truck scale, controlling the weighing gate to close, and performing a measurement on the target transport vehicle through the truck scale.

[0042] Specifically, when the target transport vehicle stops on the scale, the truck scale detects the presence of the target transport vehicle on the scale, controls the weighing gate to close, and then measures the target transport vehicle once.

[0043] S203, in response to identifying a measurement completion signal, controlling the weighing gate to lift, prompting the target transport vehicle to weigh and go to the target unloading area.

[0044] Specifically, when the truck scale obtains the current weight of the target transport vehicle and sends the current weight to the main control unit, the main control unit will generate a measurement completion signal and send it to the truck scale. The truck scale controls the lifting of the weighing gate based on the measurement completion signal and prompts the target transport vehicle to get off the scale and go to the target unloading area.

[0045] On the basis of the above technical solutions, Figure 3 Flow chart of another method for managing the purchase of materials provided by the present invention. Figure 3 As shown, in S202, in response to identifying that there is a target transport vehicle on the truck scale, after controlling the weighing gate to close, and before measuring the target transport vehicle once through the truck scale, the management method further includes:

[0046] S301, starting an infrared grating detection device for verifying whether a target transport vehicle is within a preset weighing range.

[0047] Specifically, when there is a target transport vehicle on the truck scale and the weighing gate is closed, the truck scale will also control the start-up of an infrared grating detection device, which can detect in real time whether the target transport vehicle is within a preset weighing range to prevent deviations in the vehicle's parking position, possible cheating, and inaccurate weighing.

[0048] S302, in response to receiving the identity verification information, verifying the identity of the target transport vehicle using the identity verification information.

[0049] Specifically, after the infrared grating detection device is turned on, the driver uses the control cabinet module at the vehicle scale to swipe the card, and uses the system to obtain the identity authentication information provided by the card, so that the system uses the identity authentication information to perform a second verification of the identity of the target transport vehicle, where the identity authentication information includes the identity identification of the target transport vehicle carried by the card, the type of materials, etc.

[0050] S303, in response to successful identity authentication, performing a measurement of the target transport vehicle through a vehicle scale.

[0051] Specifically, after the identity verification is completed, the truck scale begins to measure the target transport vehicle.

[0052] Optionally, Figure 4 is a flow chart of another method for managing purchased materials provided by an embodiment of the present invention, such as Figure 4 As shown, after prompting the target transport vehicle to unload and go to the target unloading area in S203, the management method further includes:

[0053] S401, in response to identifying an identity mark of a target transport vehicle in a target unloading area, controlling the target unloading area to be opened for the target transport vehicle to unload.

[0054] Specifically, the target unloading area for the target transport vehicle is the unloading area pre-assigned when the vehicle enters the factory gate. After the target transport vehicle drives to the target unloading area, the driver swipes the card at the self-service terminal so that the self-service terminal at the target unloading area can obtain the identity of the target transport vehicle and transmit the obtained identity to the main control unit. After identifying the identity, the main control unit controls the opening of the target unloading area for the target transport vehicle to unload.

[0055] S402, in response to identifying the unloading completion signal, prompting the target transport vehicle to go to the truck scale.

[0056] Specifically, after the target transport vehicle completes unloading, the card is swiped again, and the self-service terminal transmits the acquired identity of the target transport vehicle to the main control unit again. After identifying the identity, the main control unit generates an unloading completion signal and transmits it to the target unloading area. The target unloading area will prompt the target transport vehicle to go to the truck scale for secondary measurement based on the unloading completion signal.

[0057] Alternatively, if Figure 4 As shown, after prompting the target transport vehicle to go to the truck scale in S402, the management method further includes:

[0058] S403, in response to identifying the identity of the target transport vehicle at the truck scale, controlling the weighing gate to be lifted to allow the target transport vehicle to be weighed.

[0059] Specifically, when the target transport vehicle drives to the truck scale again, the truck scale recognizes the identity of the target transport vehicle and then lifts the reporting gate under the control of the master control unit to allow the target transport vehicle to be weighed.

[0060] S404, in response to identifying the presence of the target transport vehicle on the truck scale, controlling the weighing gate to close.

[0061] Specifically, when the target transport vehicle stops on the scale, the truck scale detects the presence of the target transport vehicle on the scale and controls the weighing gate to close.

[0062] S405 , in response to receiving the identity verification information, verifying the identity of the target transport vehicle using the identity verification information.

[0063] Specifically, the driver uses the control cabinet module at the truck scale to swipe the card, and uses the system to obtain the identity verification information provided by the card to verify the identity of the target transport vehicle.

[0064] S406, in response to successful identity authentication, a second measurement is performed on the target transport vehicle using a truck scale, and the weight of the materials carried by the target transport vehicle is calculated.

[0065] Specifically, after the identity verification is completed, the target transport vehicle is measured twice, and the weight of the materials carried by the target transport vehicle is obtained by subtracting the results of the first measurement and the second measurement, and the weight of the materials is recorded and stored in the system.

[0066] S407, in response to recognizing the signal that the material weight calculation is completed, controlling the weighing gate to be lifted, prompting the target transport vehicle to weigh and leave the factory.

[0067] Specifically, after the material weight calculation is completed, the main control unit generates a material weight calculation completion signal and transmits the signal to the truck scale. The truck scale controls the lifting of the weighing gate based on the received material weight calculation completion signal, and prompts the target transport vehicle to unweigh and leave the factory.

[0068] Alternatively, if Figure 4 As shown, after prompting the target transport vehicle to unload and leave the factory area in S407, the management method further includes:

[0069] S408, in response to the gate post identifying the card making and returning application of the target transport vehicle, controlling the printing of the weighing slip of the target transport vehicle, wherein the weighing slip is a weighing record voucher of the materials carried by the target transport vehicle.

[0070] Specifically, when the target transport vehicle leaves the truck scale based on the prompt and drives to the factory gate, the driver uses the self-service terminal at the gate to apply for card making and return. After receiving the card making and return application transmitted by the self-service terminal, the main control unit controls the self-service terminal to print the weighing slip of the target transport vehicle. The driver can collect the weighing slip as a certificate for material distribution and weighing.

[0071] S409, in response to the gate identifying the identity of the target transport vehicle, verifying whether the business process of the corresponding target transport vehicle is completed based on the identity.

[0072] Specifically, after receiving the weighing slip, the driver drives to the access control location at the gate. The access control automatically identifies the identity of the target transport vehicle, which may be the license plate number of the target transport vehicle. The general control unit verifies the business process of the target transport vehicle based on the identity identified by the access control, and generates a business process completion signal after the verification result shows that the business process of the target transport vehicle has been completed.

[0073] S410, in response to identifying a business process completion signal of a target transport vehicle, controlling the factory access to be opened to allow the target transport vehicle to leave.

[0074] Specifically, after the production business process is completed, the master control unit transmits the business process completion signal to the gate, and the gate controls the door to open based on the signal to allow the target transport vehicle to leave.

[0075] On the basis of the above technical solutions, Figure 5 Flow chart of another method for managing the purchase of materials provided by the present invention. Figure 5 As shown, before S101 responds to identifying the identity of the target transport vehicle in the sampling area, the management method further includes:

[0076] S501, in response to a received card making application of a target transport vehicle, controlling the generation of a card making application of the target transport vehicle, wherein the card making application carries the identity identification and material type of the target transport vehicle.

[0077] Specifically, after the driver arrives at the factory in the target transport vehicle carrying the purchased materials, he can first perform self-service card making at the self-service terminal at the factory gate. The driver can enter the vehicle license plate number and other information at the self-service terminal. Since the system will input and store the material procurement information by business personnel at preset intervals, when the driver enters the relevant information of the card making application, the system will automatically match the received information with the stored material procurement information and generate a card. The card carries information such as the target unloading area of ​​the target transport vehicle.

[0078] By using self-service terminals to enable drivers to make their own cards, the card-making business is no longer restricted by the time when the business personnel are not on duty, handovers, or going to and from get off work. Self-service cards can be made 24 hours a day and can be picked up at any time, which improves the efficiency of material warehousing and reduces labor costs.

[0079] S502, in response to a card making completion signal, generating a queue number for the target transport vehicle to enter the factory area.

[0080] Specifically, after completing the card making, the main control unit will generate a card making completion signal, and based on the card making completion signal, generate a queue number for the target transport vehicle to enter the factory area, and automatically add the vehicle to the queue of the factory area, avoiding the traditional offline notification of queuing to enter the venue, such as business personnel accepting items, drivers cutting in line and cheating, etc.

[0081] S503, in response to the arrival information of the target transport vehicle, notifying the target transport vehicle to prepare to enter the factory.

[0082] S504, in response to identifying the identity of the target transport vehicle at the gate, controlling the factory access to open so that the target transport vehicle can enter the factory, and prompting the target transport vehicle to go to the sampling area.

[0083] Specifically, when the queue shows that the target transport vehicle has arrived, the target operation vehicle will be notified or prompted. The target transport vehicle will drive to the factory gate based on the notification. After the identity recognition module at the gate recognizes the identity of the target transport vehicle, it will automatically open the access control to allow the target transport vehicle to enter the factory and prompt the target transport vehicle to go to the sampling area. By allowing the target transport vehicle to enter the factory through automatic identification and release, drivers who jump the queue or fail to make a card as required can be denied entry to the factory, which is more standardized for the warehousing management of purchased materials.

[0084] Alternatively, if Figure 5 As shown, before responding to the received card making application of the target transport vehicle in S501, the management method further includes:

[0085] S505, receiving and storing material procurement information at preset intervals, wherein the material procurement information at least includes: material type, material quantity, transportation vehicle information, unloading area information, procurement unit information, and estimated time of arrival at the factory.

[0086] Specifically, the preset time is usually set to one day, and the business personnel at the gate will maintain the material procurement information of the day according to the requirements of the factory every day, store the material procurement information of the day in the system, and lock the basic information of the document so that it cannot be changed at will. In this way, the system can automatically generate a card based on the pre-stored material procurement information and the driver's card application.

[0087] By changing the traditional offline communication and coordination of unloading area assignment to pre-storing information and using self-service card making to mark the target unloading area, labor costs are saved and possible cheating in the designated unloading area is effectively prevented.

[0088] In the embodiment of the present invention, full-process data supervision is realized to ensure the data security of the factory area, and the human resource cost expenditure is greatly reduced. While improving logistics efficiency, the real-time requirements for data query in different office locations are met. The original business personnel at nodes such as drivers coming to the factory to make cards, drivers taking samples, weighing and measuring, dividing warehouses, and returning cards are all reduced, reducing the occurrence of human cheating and realizing unmanned self-service business processing in the factory. Drivers handle business by themselves, and there is no need to wait for the entire measurement process, achieving the effect of immediate processing and leaving after completion. Business personnel can remotely monitor the driver's business processing through the management system, and the system intelligently classifies and statistics the data, greatly reducing manual data maintenance work and reducing labor intensity. The system automatically verifies information such as customer funds and vehicle business integrity, reducing factory losses and manual verification problems, ensuring the accuracy of data and effectively protecting corporate benefits.

[0093] The master control unit is also used to assign sample codes to each collected material sample and control the sampling machine to send the material samples to the testing area for testing;

[0094] The master control unit is also used to prompt the target transport vehicle to go to the truck scale after receiving the material sample sampling completion signal transmitted by the sampling machine.
