Description

Technical Field

[0001] This invention relates to the field of intelligent drug delivery technology, and in particular to an intelligent methyl bromide drug delivery system. Background Technology

[0002] Methyl bromide is an organic compound with the chemical formula CH3Br. It is a colorless, volatile gas at room temperature, but can become liquid under pressure or low temperature. Its main function is as a highly effective fumigant, capable of penetrating media such as goods, wood, and soil to kill harmful organisms such as insects, insect eggs, fungi, and weed seeds.

[0003] Currently, existing technologies heavily rely on manual operation for drug dosing. This requires manually inputting dosing information and adjusting the flow rate, and monitoring the amount of methyl bromide in the cylinder using manual experience or simple tools. This process is not only cumbersome and inefficient, but also prone to human error or misjudgment, leading to significant deviations between the dosage and the target value, making it impossible to accurately match actual dosing needs. Furthermore, the vaporization temperature is often fixed or manually adjusted, failing to dynamically optimize based on the actual vaporization state of the methyl bromide. Inaccurate temperature control often results in unstable vaporization efficiency, with some liquid methyl bromide failing to fully vaporize into a gaseous state, causing both drug waste and directly impacting subsequent dosing effectiveness.

[0004] Therefore, a methyl bromide intelligent dosing system is proposed to solve the above problems. Summary of the Invention

The control module controls the opening and closing of the dosing valve module based on the information input from the human-machine interaction module and the real-time data from the weighing module, and triggers the vaporization module to work through a preset dosing amount calculation model. The dosing valve module is used to regulate the dosing flow rate of bromomethane; the vaporization module is used to vaporize liquid bromomethane into gas; and the upload module is used to upload various information during the dosing process to the cloud platform to achieve traceability management of dosing data.

[0007] Preferably, the human-computer interaction module has a drug dosing parameter preset function, which can set the allowable range of drug dosing rate [v] minv max ]; Among them, v min For the minimum dosing rate, v max This represents the maximum drug delivery rate; The control module combines the rate range with the real-time data from the weighing module to dynamically adjust the opening of the dosing valve module.

[0008] Preferably, the weighing range of the weighing module is [m min m max It can meet the weighing requirements of methyl bromide in various types of steel cylinders, and the weighing accuracy meets the requirement of relative error δ≤0.1% to ensure the accuracy of the dosage.

[0009] Preferably, the cylinder interface of the system adopts a quick-connect structure that conforms to cylinder standards and is equipped with a leak-proof valve, the sealing pressure of which meets the following requirements: P seal ≥P gas +ΔP; Among them, P gas ΔP represents the gas pressure of methyl bromide inside the cylinder, and ΔP is the safety margin to ensure that leakage is minimized during cylinder connection.

[0010] Preferably, the preset drug dosing calculation model in the control module is as follows: M t =M0-k·t; Among them, M t M0 represents the mass of methyl bromide remaining in the cylinder at dosing time t, M0 represents the initial total mass of methyl bromide in the cylinder before dosing, and k represents the mass of dosing per unit time. The control module calculates the remaining dosage in real time based on the model and compares it with the target dosage, dynamically adjusting the opening of the dosing valve module.

[0011] Preferably, the control module has a safety detection function, capable of real-time monitoring of the methyl bromide concentration C in the dosing environment; when the concentration C exceeds the safety threshold C... th When this occurs, the control module immediately closes the dosing valve module and triggers the alarm device.

[0012] Preferably, the vaporization module includes a temperature control unit and a vaporization efficiency monitoring unit; The temperature control unit is used to maintain the temperature of the vaporization chamber within a preset range T. set Within ±ΔT, where T set The target vaporization temperature is ΔT, and the allowable range of temperature fluctuation is ΔT. The vaporization efficiency monitoring unit calculates the vaporization efficiency by detecting the state of bromomethane before and after vaporization. And the vaporization efficiency is fed back to the control module; Where, m gas m is the mass of gaseous bromomethane after vaporization. liquid The mass of liquid bromomethane entering the vaporization module.

[0013] Preferably, when the vaporization efficiency η is lower than η th At that time, the control module controls the temperature control unit to increase the temperature of the vaporization chamber, and the temperature adjustment amount satisfies: ΔT a =k η ·(η th -η); Where, k η This is an adjustment coefficient for vaporization efficiency and temperature, until the vaporization efficiency reaches η. th and above.

[0015] Preferably, the system supports one-click start / stop function. After the drug dosing information is input in the human-machine interaction module, the control module automatically completes the drug dosage weighing, conversion of drug dosage to real-time weight, opening and closing control of drug dosing valve, and vaporization operation of methyl bromide in sequence according to the preset process. No manual intervention is required during the drug dosing process.

[0016] The present invention has the following beneficial effects: 1. In this invention, the human-machine interaction module receives basic information such as the batch and target dosage of the drug from the operator, providing the system with a precise task benchmark. The weighing module, relying on a high-precision sensor, monitors the mass of methyl bromide in the cylinder in real time at high frequency, continuously capturing dynamic changes in the dosage and forming a dynamic dosage data chain. The two modules work closely with the control module: the preset parameters of the human-machine interaction module provide the control module with adjustment targets, and the real-time data of the weighing module provides the control module with dynamic feedback. This enables the control module to accurately calculate the drug dosing progress, flexibly adjust the opening and closing rhythm and opening degree of the drug dosing valve module, and simultaneously trigger the vaporization module to start. This close linkage mechanism of human-machine interaction calibration + real-time weighing feedback + intelligent control of the control center + coordinated execution of the drug dosing valve and vaporization module completely eliminates the crude and error-prone mode of estimating dosage based on experience and manually adjusting flow rate when manually dosing drugs, significantly improving the accuracy of drug dosage and ease of operation.

[0017] 2. In this invention, within the vaporization module, the temperature control unit utilizes PID precise temperature control technology to stably maintain the temperature of the vaporization chamber within a preset range, providing a stable and suitable thermal environment for the vaporization of methyl bromide. This ensures the vaporization reaction can proceed continuously and stably. The vaporization efficiency monitoring unit captures the vaporization effect in real time and feeds it back to the control module. Based on this feedback, the control module, on the one hand, dynamically adjusts the heating intensity in conjunction with the temperature control unit to optimize vaporization conditions and enhance the promoting effect of the thermal environment on vaporization; on the other hand, it coordinates with the dosing valve module to regulate the inflow rate of methyl bromide, preventing the flow rate from exceeding the processing capacity of the vaporization chamber and ensuring that the liquid methyl bromide is fully converted into a gaseous state after entering the vaporization chamber. This mechanism of closed-loop temperature-efficiency control within the vaporization module combined with cross-module coordinated flow regulation by the dosing valve in the control module not only solves the problem of vaporization efficiency fluctuations caused by mismatch between flow rate and temperature when simply controlling the temperature, but also ensures the stability and safety of the dosing process through the matching regulation of flow rate and temperature, significantly improving the effective utilization rate of the reagent.

[0018] 3. In this invention, the upload module integrates task information from the human-computer interaction module, dosage data from the weighing module, control records from the control module, and efficiency and temperature data from the vaporization module, constructing a complete dosing data chain and uploading it to the cloud platform. This forms a complete closed loop of data acquisition, integration, uploading, and application. Its linkage with each module not only enables traceability of the dosing process and allows for quick retrieval of details such as dosage changes, vaporization effects, and environmental safety for corresponding tasks through batch information, but also provides data support for subsequent dosing process optimization. Operators can adjust parameters such as dosing rate and vaporization temperature based on historical data to continuously improve system performance. This data linkage mechanism upgrades the system from a simple dosing execution tool to a comprehensive platform with intelligent management and continuous improvement capabilities, significantly enhancing the standardization and optimizability of dosing operations.

[0019] Figure 1 This is a framework diagram of the intelligent methyl bromide dosing system of the present invention. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 The present invention provides a technical solution: a methyl bromide intelligent dosing system, the system including a human-computer interaction module, a weighing module, a control module, a dosing valve module, a vaporization module and an uploading module; The human-computer interaction module is used to input drug administration information such as batch number, target dosage, and operator. The weighing module is used to weigh the methyl bromide in the cylinder in real time to obtain dynamic data on the dosage. The control module controls the opening and closing of the dosing valve module based on the information input from the human-machine interaction module and the real-time data from the weighing module, and triggers the vaporization module to work through a preset dosing amount calculation model. The dosing valve module is used to regulate the dosing flow rate of methyl bromide; the vaporization module is used to vaporize liquid methyl bromide into gas. The upload module is used to upload various information during the drug administration process to the cloud platform to achieve traceability management of drug administration data.

[0022] The human-computer interaction module serves as the core entry point for operators to interact with the system. It is responsible for initializing the drug delivery task and configuring parameters. Operators first input the drug delivery batch B and the target drug delivery amount M through devices such as touch screens and keyboards. target Basic information such as operator's name; the human-machine interaction module has a parameter preset function, which can set the allowable range of drug delivery rate [v] min v max ],in: Vmin is the minimum dosing rate (in kg / s), which limits the minimum flow rate of the drug to prevent the rate from being too low and reducing efficiency; Vmax is the maximum dosing rate (in kg / s), which limits the maximum flow rate of the drug to prevent the rate from being too high and causing safety risks or a decrease in accuracy. The control module combines this rate range with real-time data from the weighing module to dynamically adjust the opening of the dosing valve module. The formula for calculating the current dosing rate is: Where t0 is the initial time point, m(t0) is the mass of methyl bromide in the cylinder at time t0, and the adjustment logic is as follows: 1. If v(t) <v min Increase the valve opening and increase the drug flow rate; 2. If v(t) > v max Reduce valve opening and decrease drug flow rate; 3. If v min ≤v(t)≤v max Maintain valve opening to ensure stable drug delivery.

[0023] The weighing range of the weighing module is [m min m max This system can meet the weighing requirements of methyl bromide in various types of steel cylinders, and the weighing accuracy meets the requirement of a relative error δ≤0.1% to ensure the accuracy of the dosage. The formula for calculating the relative error is: Where, m measured For weighing measurements, m actual This represents the actual mass of bromomethane; High-precision weighing provides the basis for accurate control of drug dosage, avoiding over- or under-dosing.

[0024] The system's cylinder interface adopts a quick-connect structure conforming to cylinder standards (GB15383-2011), facilitating rapid assembly and disassembly, and is equipped with a leak-proof valve. The leak-proof valve's sealing pressure meets the following requirements: P seal ≥P gas +ΔP; Among them, P seal To prevent leakage, the valve's sealing pressure, P gas ΔP represents the gas pressure of methyl bromide inside the cylinder, and ΔP is the safety margin to ensure that leakage is minimized during cylinder connection, thus guaranteeing dosing safety and methyl bromide utilization.

[0025] The gas pressure P of bromomethane inside the cylinder gas Calculate using the Antoni equation: Wherein, for methyl bromoethane: A = 6.86783, B = 851.184, C = 238.65; T is the ambient temperature outside the cylinder, and the safety margin ΔP = 50 kPa, therefore P seal ≥P gas +50.

[0026] The preset dosing calculation model in the control module is as follows: M t =M0-k·t; Among them, Mt M0 represents the mass of methyl bromide remaining in the cylinder at dosing time t; M0 represents the initial total mass of methyl bromide in the cylinder before dosing, obtained by weighing before dosing using the weighing module; k represents the dosing mass per unit time, which can be preset by the human-machine interaction module or dynamically adjusted by the control module.

[0027] The control module calculates the remaining dosage M in real time. t and the target dosage M target In comparison, dynamically adjusting the valve opening: 1. If M0-M t <M target (Insufficient dosage), adjust the valve opening according to the remaining dosage requirement and match the dosage rate k; 2. If M0-M t ≥M target (If the dosage has reached the target), close the dosing valve and stop dosing.

[0028] Dynamic adjustment: Initial If the actual dosage deviates from the theoretical value by more than 5%, adjust k accordingly. Real-time monitoring of ambient concentration C; when concentration C exceeds the safety threshold C... th Upon that time, the control module immediately executes: 1. Close the dosing valve module to stop the delivery of methyl bromide; 2. Trigger the audible and visual alarm device to alert on-site personnel to take action.

[0029] The vaporization module is used to vaporize liquid bromomethane and includes a temperature control unit and a vaporization efficiency monitoring unit. 1. Temperature control unit: Used to maintain the temperature of the vaporization chamber within a preset range T. set Within ±ΔT, where T set The target vaporization temperature is ΔT, where ΔT is the allowable range of temperature fluctuation, and the target temperature is T. set =20℃ (normal) or 25℃ (low temperature), fluctuation range ΔT = ±1℃, PID control of heater power: Where, e(t) = T meas -T set For temperature deviation, K p =2.0, K i =0.5, K d =0.1 is the PID parameter.

[0030] 2. Vaporization efficiency monitoring unit: Calculates vaporization efficiency by detecting the state of bromomethane before and after vaporization. And the vaporization efficiency is fed back to the control module; Where, m gas The mass of gaseous bromomethane after vaporization is measured by a gas flow meter; m liquid m is the mass of liquid bromomethane entering the vaporization module. liquid =M0-M t The difference is calculated from the weighing module.

[0031] When the vaporization efficiency η is lower than η th At that time, the control module controls the temperature control unit to increase the temperature of the vaporization chamber, and the temperature adjustment amount satisfies: ΔT a =k η ·(η th -η); Where, k η This is an adjustment coefficient for vaporization efficiency and temperature, until the vaporization efficiency reaches η. th and above.

[0032] Upload module by timestamp t i Upload drug administration information, including the drug administration batch B. i Real-time drug dosage M i Vaporization efficiency η i Environmental bromomethane concentration C i Build a drug delivery data chain: D={(t i B i M i η i C i )}; 1. Data is collected every 10 seconds (1 second in case of anomalies), including the timestamp t. i Batch B i Dosage M i =M0-M ti Concentration C i After being encrypted with AES-256, the data is uploaded to the cloud platform to achieve full-process traceability of drug administration data.

[0033] 2. Source tracing application: If the fumigation effect is poor (e.g., pest mortality R < 95%), adjust the dosage for the next application:

[0034] The system supports one-click start / stop. After the dosing information is entered in the human-machine interface module, the control module automatically follows the preset procedure: 1. Drug dosage weighing: Control the weighing module to obtain the initial total mass M0; 2. Dosage conversion: based on model M t =M0-k·t, converting real-time quality into the amount of drug already administered; 3. Valve opening and closing control: Based on the comparison between the amount of pesticide already administered and the target value, and the range of pesticide administration rate, control the opening and closing of the valve and the degree of opening; 4. Vaporization operation: The vaporization module is triggered, the temperature of the vaporization chamber is maintained by the temperature control unit, and the vaporization efficiency monitoring unit provides real-time feedback and adjusts accordingly.

[0035] The entire process requires no human intervention, achieving automated and intelligent drug delivery, thus improving efficiency and accuracy.

[0036] The human-machine interface module, serving as the core entry point for operators to interact with the system, not only supports convenient input of basic information such as dosage batch, target dosage, and operator, but also allows for pre-setting key parameters such as the allowable range of dosage rate. This establishes a precise task framework for the entire dosage process, clearly defining the dosage objectives and constraints. The weighing module, relying on high-precision sensors, monitors the methyl bromide mass in the cylinder in real-time at high frequency, continuously capturing dynamic changes in dosage and transmitting this data to the control module in real time. The control module, as the system's central brain, receives the preset parameters from the human-machine interface module, clearly understanding the target value and rate constraint range of the dosage task. Furthermore, based on the real-time data from the weighing module, it accurately calculates the dosage progress and dynamically adjusts the opening and closing status and degree of the dosage valve module. If the calculated dosage rate is lower than the preset minimum rate, the control module instructs the dosage valve module to increase the opening degree, increasing the dosage flow rate. If the dosing rate exceeds the preset maximum rate, the valve opening is reduced to decrease the flow rate. When the remaining dosage approaches the target dosage, the valve opening is gradually fine-tuned to ensure the final dosage precisely matches the target. Simultaneously, the control module triggers the vaporization module to start working the instant the dosing process is initiated, allowing the liquid methyl bromide to immediately enter the vaporization stage upon being dispensed. This tightly linked mechanism, combining human-machine interaction calibration, real-time weighing feedback, intelligent control from the central control unit, and coordinated execution of the dosing valve and vaporization module, completely eliminates the crude and error-prone mode of manual dosing, which relies on experience to estimate dosage and manually adjust the flow rate. From the initiation of the dosing task and real-time monitoring during the process to precise control in the execution stage, the entire chain achieves digitalization and precision. This ensures a high degree of consistency between the dosage and the target value while greatly simplifying manual operation steps, making dosing operations more convenient and reliable, and effectively avoiding over- or under-dosing problems caused by human error.

[0037] The vaporization module is the core unit for the efficient conversion of liquid bromomethane into gas. Its internal temperature control unit and vaporization efficiency monitoring unit form a closed-loop system of active regulation and real-time feedback. The temperature control unit, using PID precise temperature control technology, maintains the temperature of the vaporization chamber within a preset range, providing a stable and suitable thermal environment for the vaporization of bromomethane, ensuring the continuous and stable vaporization reaction. The vaporization efficiency monitoring unit, through a dedicated quality detection device, calculates the vaporization efficiency in real time and feeds the calculated efficiency back to the control module. Upon receiving the vaporization efficiency feedback, the control module compares it with a preset efficiency threshold. If the current vaporization efficiency is lower than the threshold, the control module, on the one hand, instructs the temperature control unit to increase the temperature of the vaporization chamber, enhancing the thermal environment's promoting effect on vaporization; on the other hand, it coordinates with the dosing valve module to regulate the inflow of bromomethane. To prevent excessive flow rate from exceeding the vaporization chamber's processing capacity and causing some liquid bromomethane to fail to vaporize fully, a mechanism combining internal temperature-efficiency closed-loop control within the vaporization module with cross-module collaborative flow regulation by the dosing valve is employed. This mechanism not only solves the problem of vaporization efficiency fluctuations caused by mismatch between flow rate and temperature when simply controlling temperature, but also ensures that liquid bromomethane can be fully and stably vaporized into a gaseous state by dynamically adjusting the matching relationship between temperature and flow rate. This not only avoids waste caused by liquid reagent residue, but also ensures that the concentration, distribution, and other indicators of gaseous bromomethane after dosing strictly meet process requirements, resulting in more stable and efficient dosing and meeting the needs of high-precision dosing scenarios.

[0038] The upload module is responsible for the full lifecycle management of drug dosing data. It is deeply integrated with modules such as human-machine interaction, weighing, control, and vaporization to form a complete closed loop of data acquisition, integration, upload, and application. Specifically, the upload module obtains task identification information such as drug batch, target dosage, and operator from the human-machine interaction module to clarify the identity of each drug dosing task; it obtains dynamic drug dosage data for the entire process from the weighing module, including the initial total mass before dosing, the remaining mass at different time points during dosing, and the final dosage, thus reconstructing the complete trajectory of drug dosage changes during the dosing process; it obtains control data such as the opening and closing records of the dosing valve, the history of opening adjustment, and safety monitoring (such as trigger actions when the ambient methyl bromide concentration exceeds the standard) from the control module, presenting the details of the system's execution logic; and it obtains data such as the temperature control parameters of the vaporization chamber (such as the target temperature and the actual temperature fluctuation curve) and the real-time changes in vaporization efficiency from the vaporization module, demonstrating the operational effect of the vaporization process.
