[0002] Based on the need to conserve resources and achieve high-yield and efficient development, adopting precise positioning and quantitative fertilization technology is one of the important ways to improve the quality and efficiency of agriculture and forestry. In recent years, our company has applied for and disclosed the utility model patents "Shoulder-mounted Agricultural and Forestry Fertilization Monitoring System and Usage Method" and "Shoulder-mounted Quantitative Fertilization System and Usage Method," both of which have achieved good quantitative and positioning effects. However, the fertilizer applicators of the above two utility models use a single Beidou / GPS positioning module for fertilization location positioning, which often results in large errors in positioning data information during use. The phenomenon of fertilization location information drifting and overlapping is quite common, and it cannot fully reflect the true location information of fertilization. There is still a large gap between this and people's requirements for precise positioning supervision of fertilization.

[0003] Therefore, it is essential to develop a fertilization system that can provide more accurate and realistic feedback on fertilization location information and better meet people's needs for precise quantitative and location-based fertilization monitoring in agriculture and forestry.

[0069] In one embodiment of this utility model, the method of using the shoulder-mounted precision positioning fertilization system of this utility model includes the following steps: Step S1: System startup: Before the fertilization operation, the Beidou / GPS receiving reference station 1 is set up at the fertilization site and the shoulder-mounted precision positioning fertilization system is started, so that the Beidou / GPS receiving reference station 1, the Beidou / GPS receiving mobile station 2, the shoulder-mounted quantitative fertilizer applicator 32, the server 4 and the user terminal 5 are in the startup state, and the Beidou / GPS receiving reference station 1, the Beidou / GPS receiving mobile station 2 and the Beidou / GPS satellite navigation and positioning system maintain mutual communication.

[0070] Step S2: Fertilizer metering: Fill the fertilizer bag 321 with fertilizer, fill the metering device 324 with fertilizer from the fertilizer bag 321 through the feed pipe 323, and complete the fertilizer metering according to the volume set in the metering device 324.

[0071] Step S3: Quantitative fertilization: Align the metering device 324 with the top of the fertilization pit, open the metering device 324 to allow the fertilizer in the metering device 324 to fall completely into the fertilization pit;

[0072] Step S4: Fertilizer positioning information generation: While the quantitative fertilizer applicator 3 is applying fertilizer to the fertilizer pit, the control module 327 reads the high-precision fertilizer positioning data information of the Beidou / GPS receiving mobile station 2 located in the fertilizer pit and after the error has been corrected by the Beidou / GPS receiving reference station 1.

[0073] Step S5: Fertilizer positioning data storage and retrieval: The shoulder-mounted quantitative fertilizer applicator 32's shoulder-mounted fertilization control module 327 issues a command to control the shoulder-mounted fertilization mobile communication module 326 to read the Beidou data.

[0074] The high-precision fertilization positioning data of the GPS receiving mobile station 2 located in the fertilization pit is transmitted to the server 4 for storage. The high-precision fertilization positioning data of each fertilization pit can be queried and retrieved by logging into the server 4 through the mobile phone user terminal 51 and the PC user terminal 52, so that the fertilization management personnel can monitor and check whether the fertilization operators are performing fixed-point precise fertilization as required.

[0075] In another specific embodiment of the method of using the shoulder-mounted precision positioning fertilization system of this utility model, the specific steps of the method of use are similar to those of the previous embodiment, the only difference being:

[0076] In step S3, when the fertilization operator puts the fertilizer from the metering device 324 into the fertilization pit, the control module 327 issues a command to control the camera 329 to take a real-time photo of the fertilization pit.

[0077] In areas without mobile communication signals, the fertilization positioning data information of the Beidou / GPS receiving mobile station 2 read by the shoulder-back fertilization control module 327 in step S4 is temporarily stored in the shoulder-back fertilization control module 327 in areas without communication signals. After the fertilization operation is completed, the shoulder-back quantitative fertilizer applicator 32 enters an area with communication signals and automatically uploads and stores the fertilization positioning data information to the server 4. At this time, the user can log in to the server 4 through the mobile phone user terminal 51 to query and call the high-precision fertilization positioning data information of each fertilization pit.

[0078] It should be added that by filling the shoulder-mounted quantitative fertilizer applicator 32 with fertilizer, a relatively stable amount of fertilizer is obtained. When fertilizing, all the fertilizer in the applicator 324 is put into the fertilization pit, thereby ensuring that the amount of fertilizer applied to each fertilization pit is the same.

[0082] The specific operating method is as follows:

[0083] Step S1: System Startup: Before fertilization, start the shoulder-mounted precision positioning fertilization system, so that the shoulder-mounted quantitative fertilizer applicator 32, the server 4, the mobile phone user terminal 51 and the PC user terminal 52 are in the startup state, and the Beidou / GPS positioning module maintains a connection and communication state with the Beidou / GPS satellite navigation and positioning system.

[0084] Step S2: Fertilizer barcode scanning and positioning: Align the barcode scanning module 330 on the shoulder-mounted quantitative fertilizer applicator 32 with the QR code on the fertilizer packaging bag to be applied, press the shoulder-mounted fertilizer application switch 325 to scan the QR code on the fertilizer packaging bag, and the control module 327 reads the QR code information on the fertilizer packaging bag and the positioning data information corresponding to the bag of organic fertilizer from the Beidou / GPS positioning module 2 once each;

[0085] Step S3: Fertilizer barcode scanning and location data storage: The control module 327 of the shoulder-mounted quantitative fertilizer applicator 32 issues an instruction to control the shoulder-mounted fertilizer applicator mobile communication module 326 to transmit the read fertilizer packaging bag QR code information and the location data information of the Beidou / GPS positioning module 2 on the fertilizer bag to the server 4 for storage.

[0086] Step S4: Fertilizer quantification: The fertilizer scanned in S3 is loaded into the fertilizer bag 321. The fertilizer in the fertilizer bag 321 is filled into the metering device 324 through the feed pipe 323. The fertilizer quantification is completed according to the volume set in the metering device 324.

[0087] Step S5: Quantitative fertilization: Align the metering device 324 with the top of the fertilization pit, open the metering device 324 to allow the fertilizer in the metering device 324 to fall completely into the fertilization pit;

[0088] Step S6: Fertilizer positioning information generation: While the quantitative fertilizer applicator 3 is applying fertilizer to the fertilizer pit, the control module 327 reads the high-precision fertilizer positioning data information of the Beidou / GPS receiving mobile station 2 located in the fertilizer pit and after the error has been corrected by the Beidou / GPS receiving reference station 1.

[0089] Step S7: Storage and Query of Fertilizer Positioning Data: The control module 327 of the quantitative fertilizer applicator 3 issues an instruction to control the mobile communication module 326 to transmit the high-precision fertilizer positioning data information of the Beidou / GPS receiving mobile station 2 located in the fertilizer pit to the server for storage. By logging into the server 4 through the user terminal 5, users can query and call the high-precision fertilizer positioning data of each fertilizer pit and the data information corresponding to the fertilizer pack scanned in S2, so that fertilizer management personnel can monitor and check whether the fertilizer operators are performing fixed-point precise fertilization as required.
