Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural equipment, in particular to a wearable agricultural operation device integrated with sensors. BACKGROUND

[0002] In modern agricultural production, the use of pesticides, herbicides and other chemicals has ensured crop yield, but the health risks faced by operation personnel are prominent. Traditional operations rely on experience to judge exposure risks and cannot accurately perceive environmental dynamic changes such as high temperature accelerating pesticide volatilization and high wind speed expanding aerosol diffusion. Moreover, there is a lack of monitoring of the vital signs of operation personnel, making it difficult to cope with the increased risk sensitivity caused by individual physiological differences and posing a greater health risk.

[0003] The current agricultural field lacks a "environment-individual-dose" coordinated management system, and the operation time length mostly adopts fixed standards without considering the dynamic influence of environmental parameters and individual state on safe dose. This static mode cannot adapt to the differentiated safety threshold of different toxic chemicals and is prone to "risk underestimation" or "overprotection" problems in complex environments. At the same time, existing devices have single functions and lack data integration and intelligent analysis capabilities, making it difficult to achieve full-process automated management from risk perception to early warning and failing to meet the intelligent needs of modern agricultural safe operation.

A shoulder strap 2 is fixedly connected to the outer wall of the waist belt 1. The shoulder strap 2 is tightly connected to the waist belt with a high-strength stitching process to stably support various sensors and components on the equipment.

[0029] The environmental data acquisition component 4, located on the outer wall of the shoulder strap 2, is used to continuously collect environmental information in real time. The strategic placement of this component ensures accurate capture of micro-environmental data around the operator. The alarm device 3 is fixedly connected to the outer wall of the shoulder strap 2. This position allows the operator to quickly perceive alarm prompts in any working posture. The alarm device 3 can be an audible and visual alarm to alert the operator in various ways. The control component 5 is connected to the environmental data acquisition component 4 and the alarm device 3 via a signal. It is used to collect the operator's vital signs information and provide the operator with an interactive operating platform, enabling them to easily set up equipment and query data.

[0030] The environmental data acquisition component 4 includes a temperature sensor 41 and a wind speed sensor 42. These sensors together constitute a key data source for dynamic risk assessment. Multiple sets of temperature sensors 41 are provided and are fixedly connected to the front and rear surfaces of the outer wall of the shoulder strap 2. By averaging the data from multiple points, the ambient temperature of the worker can be more accurately reflected. The wind speed sensor 42 is fixedly connected to the front surface of the shoulder strap 2 near the top. This position is designed to simulate the airflow conditions in the worker's breathing area to the greatest extent possible, thereby accurately assessing the risk of exposure to chemical aerosols.

[0031] The control component 5 includes a mounting plate 56. A strap 55 is fixedly connected to the lower surface of the mounting plate 56. The strap 55 is used to securely fix the control component 5 to the operator's wrist or arm to ensure that the equipment does not shake during operation. A central processing unit 51 is fixedly connected to the upper surface of the mounting plate 56. This processor is the control core of the entire equipment and is responsible for processing all data and running algorithms. The upper surface of the central processing unit 51 is arranged from back to front as follows: a display module 52, a camera module 53, and a switch 54. This layout facilitates operation by the operator and allows for intuitive viewing of information. The camera module 53 uses built-in image recognition and decoding algorithms to collect information about the chemicals used in the current operation by scanning the barcodes on the outer packaging of the chemicals used. This achieves automated and paperless data entry, greatly improving operational convenience.

[0032] The lower surface of the central processing unit 51 is equipped with a vital signs detection module 58. The unique design of this module allows it to fit closely to the body of the worker and continuously collect physiological data. The upper surface of the mounting plate 56 is provided with a through groove 57 that is compatible with the vital signs detection module 58. This through groove 57 ensures that the sensor can directly contact the worker's skin to achieve accurate data measurement.

[0033] The vital signs detection module 58 is equipped with an infrared sensor, preferably a thermopile infrared sensor. Its non-contact or contact measurement method can ensure hygiene and provide high-precision data. This module can collect a variety of data, including but not limited to the body temperature of workers, to provide reliable physiological input for subsequent personalized risk assessment.

[0034] The central processing unit 51 also includes a receiving module 511. This module is the starting point of the entire risk assessment system and is configured to receive the standard operating time (T) associated with the chemicals used in the current operation. standard The receiving module 511, through a signal connection with the camera module 53, parses the pesticide barcode or QR code scanned by the camera module 53, retrieves and obtains the corresponding chemical data from the device's built-in database or cloud database, and the physicochemical parameter model includes, but is not limited to: temperature influence coefficient (KT), wind speed influence coefficient (KW), and physiological sensitivity constant (K). phys These parameters, such as , provide the foundation for subsequent dynamic calculations.

[0035] The central processing unit 51 also includes a correction module 512, which is the core of the dynamic risk assessment. This module is signal-connected to the environmental acquisition component 4 and the receiving module 511. This module calls the physicochemical parameter model provided by the receiving module 511 in real time and, combined with the environmental information collected in real time by the environmental acquisition component 4, calculates the exposure flux correction coefficient (C) representing the ratio of the current exposure rate to the standard conditions.flux The exposure flux correction factor (C) is a key indicator for measuring the impact of environmental conditions on the risk of chemical exposure. flux The calculation is performed using the following algorithm formula:

[0036] C flux =1+KT·(T) env -T ref )+KW·W micro

[0037] Where Tref is the preset standard reference temperature, usually set to 25℃, and KT and KW are preset coefficients obtained from the physicochemical parameter model.

[0038] The central processing unit 51 also includes a management module 513, which is responsible for the lifecycle management of the safety dose budget and is configured to be based on standard operating time (T). standard Initialize a total safe exposure dose budget (B total In the simplest solution, B total The value can be directly equal to T. standard During the operation, the management module 513 can adjust the exposure flux correction coefficient (C) calculated in real time by the correction module 512. flux The consumed dose budget (B) is continuously accumulated at set time intervals (Δt). consumed ), the consumed dose budget (B consumed The cumulative algorithm is as follows:

[0039] B consumed +=C flux ·Δt

[0040] Among them, B consumed The initial value is 0. The accumulation process here can be regarded as a discretized integral process, which ensures that the dose consumption under different environmental conditions is accurately accumulated.

[0041] The central processing unit 51 also includes a prediction module 514, which is the system's decision output unit. This module is signal-connected to the management module 513, display module 52, and alarm device 3. It obtains the total safe exposure dose budget and the consumed dose budget from the management module 513 in real time, and calculates the C based on the current C... flux The remaining safe working time (T) is dynamically calculated. remaining To ensure the stability of the prediction duration, the most recent C is preferred. flux The average value is used to calculate the remaining safe working time (T). remaining The calculation formula for ) is as follows:

[0042] T remaining =(Tstandard -B consumed ) / C flux

[0043] Calculated T remaining It will be sent to the display module 52 for real-time display. When the consumed dose budget reaches the preset threshold, the module will drive the alarm device 3 to issue an alarm.

[0044] The correction module 512 or management module 513 is also connected to the vital signs detection module 58 to achieve personalized risk management. This module can be used to process the body temperature (T) of the workers collected by the vital signs detection module 58. body Physiological information, such as [missing information], is used as an additional correction factor to further personalize the exposure flux correction factor or the consumed dose budget. Specifically, this module calculates the physiologically corrected exposure flux correction factor (C [missing information]). flux' To take into account the sensitivity variations caused by individual physiological differences among workers, the personalized adjustment algorithm is as follows:

[0045] C flux' =C flux ·(1+K phys ·(T body -T base ))

[0046] Among them, K phys T is the physiological sensitivity constant preset for the system. base This is the baseline body temperature of the workers, C flux' It will replace the original C flux Incorporate dose budgeting into cumulative calculations to make the assessment results more closely reflect the individual's actual physiological load.

[0047] Working principle: When using the equipment, the operator puts on the waist belt 1 through the buckle 11. The shoulder strap 2 is fixed to the waist belt 1 to form a stable structure. The control component 5 is fixed to the wrist or arm through the strap 55, ensuring that the vital signs detection module 58 is in contact with the skin through the through groove 57 of the mounting plate 56. After the switch 54 is turned on, the camera module 53 scans the chemical barcode, and after identification and decoding, it is transmitted to the receiving module 511 of the central processor 51. The receiving module 511 retrieves parameters such as the standard operating time of the chemical and the environmental impact factor from the database and initializes the total safe exposure dose budget. The temperature sensor 41 of the environmental acquisition component 4 collects the ambient temperature in real time, the wind speed sensor 42 collects the wind speed in the breathing area, and the vital signs detection module 58 simultaneously captures the operator's body temperature and other physiological data. All information is transmitted to the central processor 51 in real time.

[0048] During agricultural operations, the central processing unit 51 performs risk assessment based on the collected data. The correction module 512 calculates personalized exposure risk coefficients by combining environmental parameters and individual physiological characteristics, quantifying the comprehensive impact of environmental and individual differences on chemical exposure risks. The management module 513 dynamically accumulates the consumed safe dose, and the prediction module 514 calculates the remaining safe working time in real time and presents it through the display module 52. When the consumed dose reaches the preset threshold, the alarm device 3 is triggered to issue an audible and visual warning, forming a closed-loop safety management system from data collection to risk warning.
