[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] See also Figure 1 and Figure 8 , an embodiment provided by the present invention: a control system based on an explosive vehicle, comprising a material identification module, wherein the material identification module is used to correctly identify various materials on the explosive vehicle, accurately track and manage the materials;

[0063] The material identification module includes: an information collection unit, a material classification unit and a material management unit, wherein the information collection unit is connected to the material classification unit via a network, and the material classification unit is connected to the material management unit via a network;

[0064] The information collection unit uses RFID technology to read the label information of the materials entering the silo, captures the material image and spectral data in real time through a high-definition camera and spectrometer, and uses a variety of sensors to collect the real-time status information of the materials, including liquid level, weight, and pressure;

[0065] The material classification unit preliminarily identifies the material type according to the material label information, extracts the material characteristics by building a material database, analyzes the material image and spectral data, compares the material characteristic data with the material database, identifies the type, quantity and state of the material, and performs secondary confirmation on the identification result;

[0066] The material management unit records and stores the type, quantity, status, feeding time and storage location data of the materials in the silo, sends out abnormal signals for insufficient material inventory and long material storage time, and sends out alarm signals for inconsistencies between the initial identification result of the material type and the secondary confirmation result;

[0067] Furthermore, when the explosive truck is loaded with materials, before the materials enter the silo, the information collection unit controls the RFID reader installed at the entrance of the silo to send out a wireless radio frequency signal to activate the RFID tag on the material container. After receiving the signal, the tag transmits the stored information back to the reader via radio waves. The information collection unit transmits the information transmitted by the reader to the material classification unit. The material classification unit preliminarily determines whether the type of loaded material is correct. After the materials enter the silo, the information collection unit uses a high-definition camera to take real-time images of the appearance of the materials, uses a spectrometer to measure the spectrum reflected or emitted by the surface of the materials, obtains the chemical composition of the materials, uses a liquid level sensor to monitor the liquid level of the materials in the silo, uses a weight sensor to measure the weight of the materials in real time, uses a pressure sensor to monitor the pressure changes inside the silo, and transmits the monitored data to the information collection unit.

[0069] The material management unit records and stores the material type, quantity, and status data transmitted by the material management unit, and records the date and storage location of the material entering the silo transmitted by the information collection unit, and sets thresholds for inventory and storage time. When it is detected that the amount of material in the silo is lower than the set threshold, an insufficient inventory signal is issued to remind the operator to replenish the material in time. When the storage time of the material exceeds the set threshold, an abnormal signal is issued for the material that has been stored for too long to avoid material expiration or deterioration. If the preliminary identification result of the material type or quantity by the material management unit is inconsistent with the secondary confirmation result, an alarm signal will be issued to prompt the staff to review and handle it to avoid loading material errors or silo leakage.

The data acquisition unit uses a density sensor to measure the density of the explosive mixture and detects the mass distribution and compactness of each component in the mixture. The material mixing module sets the standard value of the explosive mass for the data acquisition unit based on the explosive formula and safety standards.

[0105] The quality analysis unit receives the concentration and density data transmitted by the data acquisition unit, and uses the preset algorithms and models to calculate and analyze the concentration and density data, and calculates the quality parameters of the mixed explosives, such as the energy density and stability index of the explosives. The quality analysis unit compares the quality parameters with the preset standard values. If the quality parameters are consistent with the standard values, it means that the quality of the explosives is qualified, and the quality analysis unit will notify the system that the loading operation can be carried out; if the quality parameters do not meet the standard values, the quality analysis unit will send an error signal, and the material mixing module will automatically adjust the material ratio according to the type and severity of the error signal, and add or reduce the amount of material until the quality parameters are consistent with the standard values.

[0106] Working principle: During the material loading process, the material identification module uses RFID technology, image recognition and spectral analysis for multiple verifications to confirm the type, quantity and status of the material. At the same time, the safety monitoring module analyzes the material level, weight and pressure changes inside the silo in real time during this process to avoid excessive material loading. The material identification module and the material detection module work together to analyze the material storage time and material quality to avoid material deterioration.

[0107] During the material mixing process, the material mixing module receives the material type and quantity transmitted by the material identification module, selects the explosive formula, calculates the material ratio, transports the material from the silo to the automatic mixer, and adjusts the material feeding amount and feeding speed in real time. Under the control of the PLC controller, the automatic mixer adjusts the mixing speed and time to evenly mix the materials. The explosive detection module detects the mixture to determine whether the explosive is qualified. The safety monitoring module monitors the temperature and pressure of the materials during mixing in real time to ensure the stability of the environment during material mixing and prevent the risk of explosion or leakage.

[0108] The intelligent charging module formulates a charging plan and executes the charging process of the charging plan according to the explosives-related data and work requirements transmitted by the material mixing module. The charging collection unit in the 3D visualization unit collects the flow rate and charging speed of the explosives in real time and calculates the charging quantity. The intelligent charging module maps the charging speed and charging quantity to the 3D model so that the staff can check it at any time. The safety monitoring module monitors the surrounding gas concentration in real time to prevent harmful gases produced by the decomposition of explosives from harming the human body.
