Description

Technical Field

[0001] This application relates to the field of livestock showering technology, and more specifically, to a personnel showering system, method, and apparatus suitable for ranches. Background Technology

[0002] In the operation and management of large-scale, standardized ranches, biosecurity is a core element in ensuring the safety of livestock production and reducing the risk of disease transmission. Personnel, as important carriers of materials and diseases both inside and outside the ranch, require strict pre-entry bathing and disinfection procedures before entering various functional areas. This is a crucial first step in the ranch's biosecurity system. Currently, large and medium-sized ranches in China have established basic management standards for personnel bathing and disinfection, requiring personnel entering different risk levels such as general areas, quarantine areas, and slaughter areas to perform corresponding cleaning and disinfection procedures. These standards also specify basic requirements for bathing duration and disinfection procedures. The compliance of personnel bathing and disinfection directly impacts the overall biosecurity level of the ranch.

[0003] Traditional ranch personnel bathing and disinfection often rely on manual control and simple spraying methods, which suffer from significant problems such as non-standard process execution and crude control measures. On the one hand, it is impossible to match differentiated bathing and disinfection procedures according to personnel identity and the risk level of the areas they intend to enter and exit. Applying the same operating standards to ordinary areas and high-risk isolation areas can easily lead to insufficient disinfection in high-risk areas or waste of resources in low-risk areas. On the other hand, the bathing process depends on the self-discipline of personnel, and there is a lack of real-time monitoring of bathing actions, duration, and dosage of agents. This can lead to cheating behaviors such as personnel simplifying procedures and violating regulations, making it difficult to guarantee the actual cleaning and disinfection effect. At the same time, the manual recording of bathing information is inefficient, error-prone, and cannot form a complete bathing compliance data ledger, which is not conducive to subsequent biosafety traceability and management.

[0004] Therefore, there is an urgent need for a personnel shower system, method, and device suitable for ranches to solve the problem of inadequate disinfection when personnel enter livestock farms. Summary of the Invention

[0024] like Figure 1 As shown, in a first aspect, this application provides a personnel shower system suitable for ranches, including a sensing and identification module, a central control module, a spray module, a water supply and disinfection module, and a linkage interface module.

[0025] The perception and recognition module is used to acquire the identity information of bathers and bathing status data. The bathing status data includes at least ambient temperature information, bathing water temperature information, and bather's location and posture information.

[0026] As the core unit for data acquisition and identity verification of the system, the perception and recognition module, through the collaborative work of the identity recognition unit and the data acquisition unit, acquires the identity information of bathers and multi-dimensional status data during the bathing process, providing a reliable basis for the central control module to generate target bathing process parameters and control instructions.

[0027] Specifically, the perception and recognition module includes an identity recognition unit and a data acquisition unit.

[0028] The identity recognition unit uses the account input module to receive the information input by the bather and forms the bather's identity information, or uses an RFID card reader to read the bather's identification card and forms the bather's identity information.

[0029] Specifically, the identity recognition unit is used to accurately verify the identity of bathers and establish a basis for linking their identity with the work area of ​​the ranch. It can be installed on the control panel area of ​​the shower head casing of the intelligent sprinkler module (for easy operation). Specific implementation methods may include: Account input module: Equipped with a waterproof mechanical keyboard or touch keyboard, it supports bath staff to input preset employee ID, password and other identity information. After input, it automatically verifies and generates complete identity information including "employee ID-position-intended entry / exit area".

[0030] RFID reader: It adopts a high-frequency RFID read / write module (working frequency 13.56MHz), which is compatible with the identification carriers such as personnel wristbands and smart cards uniformly distributed by the ranch. It can quickly obtain the identity data stored in the carrier through non-contact reading (sensing distance 0-5cm) without manual operation, thus improving the convenience of use. After reading, it automatically associates the personnel's job type (such as feeder, veterinarian, visitor) and the area to be entered or exited (ordinary breeding area, isolation area, slaughtering area) and other core information to form a standardized identity data format, ensuring accurate matching with the standardized bathing process library of the central control module.

[0031] The data acquisition unit is used to collect data on the environmental status, water flow status, and personnel movement status of the bathroom in real time, ensuring the accuracy of data acquisition and the stability of the equipment. Specifically, it includes temperature sensors, water temperature sensors, and radar sensors.

[0032] Furthermore, the temperature sensor is installed in the bathing area to collect ambient temperature information within the area. The temperature sensor can be a digital sensor, fixed to the top or side wall of the bathing area (30cm outside the showerhead's water flow range) with bolts, which can, to some extent, prevent direct water splashing from affecting measurement accuracy. The preferred measurement range of the temperature sensor is 0-50℃, and the preferred measurement accuracy is ±0.5℃. It can capture real-time changes in ambient temperature within the bathing room, and the data update frequency can be set as needed, for example, once every 10 seconds, to ensure the real-time nature of the room temperature data. The temperature sensor housing is treated with an acid and alkali resistant coating, suitable for the humid and corrosive environment of the ranch's bathing room.

[0033] The water temperature sensor is positioned along the water flow path in the bathing area to collect momentary water temperature information. The water temperature sensor can be installed in a pipe, or in other locations as needed, such as fixing it to the water supply pipe near the showerhead outlet (the water flow path), directly contacting the water flow to obtain accurate water temperature data. The preferred measurement range is 0-100℃, and the preferred measurement accuracy is ±0.3℃. It can monitor the temperature changes of clean water and foam disinfectant water in real time, with a data update frequency of once every 5 seconds, ensuring the central control module promptly obtains water temperature deviations. The water temperature sensor interface adopts a sealed design to prevent short circuits caused by leakage, adapting to various water supply pipe installation scenarios.

[0034] The radar sensor is installed in the shower area to collect the position and posture of the shower personnel, forming their position and posture information. The radar sensor can be installed on the top or side of the showerhead casing (in an unobstructed location). It uses millimeter-wave radar detection principles, emitting low-power millimeter waves into the shower area and receiving the reflected echoes to capture the position coordinates and changes in body movements of the personnel. The detection range covers the entire shower area (3-4 meters in diameter), with a response time of ≤0.1 seconds. It can accurately identify whether a person is within the designated shower area, and distinguish between valid shower actions (rubbing, turning, raising hands, etc.) and invalid states (standing still, leaving the area, etc.). The radar sensor uses non-contact detection, is unaffected by water flow or mist, and is corrosion-resistant and waterproof, adapting to the humid environment of the shower room. The generated personnel position coordinates (X / Y / Z axes) and movement status data provide direct evidence for the central control module to determine the validity of the shower.

[0035] For example, the perception and recognition module, as a data acquisition and identity recognition mechanism, is used to acquire personnel information and bathing status data to provide a basis for regulation and control. It is used to identify personnel identity and collect ambient temperature data and bathing water temperature data in real time. The human body status sensor adopts a radar sensor, which is installed on the shower head shell to sense the position of the human body and realize intelligent control of human body position recognition and human body movement recognition, so as to avoid water waste.

[0036] The central control module, connected to the sensing and identification module, is used to receive the bather's identity information and bathing status data, associate the bather's identity information with the work area to form target bathing process parameters, and generate control instructions based on the difference between the bathing status data and the target bathing process parameters.

[0037] The central control module, as the system's control unit, integrates the control unit and the main control chip. It receives data and issues commands through wireless communication. Relying on a standardized bathing process library and control logic, it accurately matches bathing parameters and generates control commands. It connects with the sensing and identification module, the spray module, the water supply and disinfection module, and the linkage interface module to ensure that the bathing process is standardized, the parameters are optimized, and the management and control are intelligent.

[0038] Specifically, the central control module includes: a control unit and a standardized bathing process library.

[0039] Furthermore, the control unit includes a main control chip and a wireless communication module.

[0040] The wireless communication module is connected to the sensing and identification module and the main control chip respectively, and is used to transmit the bather's identity information and the bathing status data to the main control chip.

[0041] The main control chip includes a standardized bathing process library and control algorithms.

[0042] It should be noted that the wireless communication module can use the WiFi communication protocol (compatible with 802.11b / g / n standards) to ensure real-time transmission of identity information and status data without delay; at the same time, it has a built-in signal enhancement antenna, and the communication distance covers the bathroom and surrounding area within a 10-meter range to avoid data loss due to signal attenuation; the module has a moisture-proof and corrosion-proof sealed packaging design, and is directly connected to the main control chip through onboard circuitry, converting the "personnel identity information + multi-dimensional bath status data" collected by the sensing and recognition module into standardized digital signals, which are then transmitted to the main control chip for processing.

[0043] The main control chip can adopt a dual-chip collaborative architecture (industrial-grade HC32 chip + ESP32 chip), which has high stability and strong anti-interference capabilities, and is suitable for the harsh working environment of the ranch. The HC32 chip is responsible for main logic operation, peripheral driver and instruction generation, while the ESP32 chip assists in network communication and advanced parameter optimization. The two interact with each other in real time through an internal bus to ensure computing efficiency. The chip integrates multiple I / O interfaces, analog signal acquisition interfaces and communication interfaces, which establish hardware connections with wireless communication modules, memory, driver circuits and linkage interface modules to realize a closed loop of data reception, computing and processing and instruction output.

[0044] The standardized bathing process library includes bathing processes corresponding to multiple work areas, wherein the multiple work areas include at least one of a general breeding area, an isolation area, and a slaughtering area.

[0045] Specifically, the standardized bathing process library is a "compliance process benchmark library" pre-stored in the built-in flash memory of the main control chip. It is constructed according to the risk level of the work area. Each category contains complete core information such as bathing stages, duration, and parameter thresholds, and supports dynamic updates by receiving instructions from the host computer through the linkage interface module.

[0046] For example, the work areas in the standardized bathing process library correspond to the general breeding area, quarantine area, and slaughtering area as follows: For ordinary aquaculture areas (low risk): the process is "clean water for 3 minutes → foam disinfection for 20 seconds → rinse with clean water for 2 minutes"; the parameter thresholds include water temperature 36-44℃, room temperature 18-28℃, water flow rate 4-9L / min, and total water consumption 20-60L; the core requirement is basic cleaning and disinfection, while also taking into account water and energy conservation.

[0047] Isolation area (medium risk): The process is "clean water for 5 minutes → foam disinfection for 2 minutes → rinse with clean water for 3 minutes"; the parameter thresholds include water temperature 38-42℃, room temperature 20-26℃, water flow rate 5-7L / min, and total water consumption 50-100L; the core requirement is to strengthen the disinfection time to ensure that pathogens are completely eliminated.

[0048] Slaughtering area (high risk): The process is "cleaning with clean water for 8 minutes → foam disinfection for 3 minutes → rinsing with clean water for 5 minutes"; the parameter thresholds include water temperature 38-42℃, room temperature 20-26℃, water flow rate 6-8L / min, and total water consumption 60-120L; the core requirement is an ultra-long cleaning and disinfection process to adapt to high pollution scenarios.

[0049] The standardized bathing process library management mechanism can use structured data format for storage. Each process includes fields such as "stage number-duration-parameter threshold-execution conditions". It supports receiving update instructions from the ranch personnel management system and biosafety management system through the linkage interface module, realizing online modification, addition or deletion of process parameters, and upgrading can be completed without disassembling the equipment.

[0050] The control algorithm is connected to the standardized bathing process library and is used to determine the optimal bathing parameters based on the bather's identity information and the bathing process corresponding to the work area in the standardized bathing process library. The optimal bathing parameters include water temperature, room temperature, water flow rate, bathing duration, and water consumption.

[0051] It should be noted that the control algorithm is based on the parameter matching logic of "optimal cost within compliance boundaries". It does not require a complex calculation model. Through "basic parameter matching + dynamic optimization adjustment", it combines the identity information of bathers with a standardized bathing process library to output the optimal bathing parameters (water temperature, room temperature, water flow rate, bathing duration, water consumption). The specific principle is as follows: Basic parameter matching: First, based on the association between "personnel identity information and intended work area" transmitted by the perception and recognition module, the parameter threshold range of the corresponding area is retrieved from the standardized bathing process library (such as the water temperature of 38-42℃ and the duration of 16min associated with high-risk processes for staff in the slaughtering area). This range is used as the "compliance boundary" of the optimal parameters to ensure that the parameters do not exceed biosafety requirements.

[0052] Cost optimization: Within compliance boundaries, dynamic adjustments are made based on historical bathing data (stored in memory), with the core objective of minimizing water consumption and energy consumption. Water flow optimization: Prioritize the lower limit value within the range (e.g., water flow threshold of 5-7L / min for isolation area, initially matched to 5L / min). If historical data shows that the person's action efficiency is high (effective scrubbing rate ≥80%), maintain the lower limit value; if the action efficiency is low, fine-tune to the middle value (6L / min) to ensure cleaning effect while reducing waste.

[0053] Time optimization: Based on the minimum time in the process library (e.g., the total time for a typical breeding area is 5 minutes), if there is no cheating record in the personnel's historical bathing and the actions are efficient, maintain the benchmark time; if there are delays in the actions, appropriately shorten it to the benchmark time (to avoid unnecessary time consumption), while ensuring that the time for each stage reaches the standard (e.g., the cleaning stage is not less than 3 minutes).

[0054] Temperature and humidity optimization: Water temperature is prioritized to match the compliant value of the personnel's historical preferences (e.g., if a person's historical bath water temperature is mostly 39℃ and it is within the 38-42℃ range in the isolation area, 39℃ will be directly matched). The room temperature is set to the lower limit of the range by default (e.g., 20℃) to reduce heating energy consumption. The temperature adjustment will only be started when the ambient temperature is lower than the lower limit.

[0055] Anomaly Adaptation and Adjustment: If the real-time bathing status data (such as water temperature and personnel movement) transmitted by the sensing and recognition module deviates from the optimal parameters by more than ±10%, the algorithm triggers dynamic correction and generates control instructions (such as instructing the water supply module to raise the temperature when the water temperature is below 38℃; instructing the interaction module to remind and pause the accumulation of time when the personnel are still for more than 30 seconds), to ensure that the process execution does not deviate from the optimal parameters.

[0056] In one embodiment, the modulation algorithm is a target convolutional neural network model, comprising: Historical bather identity information is obtained, and the bathing process corresponding to the work area in the standardized bathing process library is used as training data to train a convolutional neural network model to obtain a target convolutional neural network model. The target convolutional neural network model represents the optimal solution for water temperature, room temperature, water flow rate, bathing time, and water consumption under the bathing process corresponding to the work area, with the lowest cost, and outputs the optimal solution for water temperature, room temperature, water flow rate, bathing time, and water consumption.

[0057] Specifically, the control algorithm is a target convolutional neural network model. It learns adaptation patterns from historical bathing data and, under the compliance constraints of a standardized bathing process library, automatically outputs the optimal bathing parameters (water temperature, room temperature, water flow rate, bathing duration, and water consumption—these parameters can be collected through appropriate sensors; this application does not limit the type or model of the sensors) to achieve personalized and precise parameter matching without manual intervention. The details are as follows: The training data for the target convolutional neural network model is derived from historical data stored during the system's daily operation, ensuring data authenticity and scenario adaptability. The specific components include: Input data: Composite identity information of historical bathers, including employee number, job type (such as breeder, veterinarian, visitor), intended work area (ordinary breeding area, quarantine area, slaughtering area), health status (such as low temperature intolerance), etc. All information is uniquely bound to the personnel account / RFID identification carrier to ensure identity correlation.

[0058] Related constraint data: Standardized bathing process library data corresponding to the above identity information, including parameter threshold ranges for the work area (such as water temperature in the isolation area of ​​38-42℃ and water flow rate of 5-7L / min), bathing stage division (clean water cleaning → foam disinfection → clean water rinsing) and minimum duration requirements for each stage, to set insurmountable compliance boundaries for training.

[0059] Cost and effectiveness label data: Actual execution data during historical bathing processes, including the final bathing parameters used (specific water temperature, water flow rate, etc.), total water consumption (water flow rate × actual duration), total energy consumption (energy consumed for heating water), and bathing compliance results (whether it passed the system's judgment, and whether there were any cheating records). Among them, "total water consumption + total energy consumption" are used as cost labels, and "compliance results" are used as effectiveness labels to ensure that the model learns parameter combinations that are "low-cost and compliant".

[0060] First, a convolutional neural network model is constructed and trained, adhering to the core principles of "compliance first, cost optimization." A lightweight network structure design is employed, adapted to the industrial-grade main control chip of the central control module (such as the HC32+ESP32 dual-chip architecture), ensuring rapid deployment and real-time response after training. The specific process is as follows: Data preprocessing: First, the collected historical data is classified and organized, and the dataset is divided into batches according to the risk level of the work area (low, medium and high) to avoid interference between the parameter patterns of different areas; then, all numerical data (such as water temperature, water flow and duration) are standardized to eliminate the difference in units, so that the convolutional neural network model can focus on learning the parameter adaptation pattern rather than the influence of numerical size.

[0061] Constraint embedding: During training, the parameter range of the standardized bathing process library is used as a hard constraint. That is, the convolutional neural network model can only select parameters within the corresponding range during the learning process. If the output parameter exceeds the range (such as the water temperature of the waiting area is 43℃), it is directly judged as an invalid learning sample, forcing the convolutional neural network model to adjust its learning direction and ensuring that the output of the trained convolutional neural network model is always compliant.

[0062] Core learning patterns: Through multiple rounds of iterative learning, the convolutional neural network model autonomously captures the correlation patterns between "composite identity information - bathing parameters - cost - target effect". For example, it learns patterns such as "slaughter workers in the waiting area + high efficiency (effective scrubbing rate ≥80%) → matching the lower limit of the water flow range of 5L / min and the minimum required duration of 16min, which can achieve the lowest cost and meet the target"; "veterinarians in the isolation area + low temperature intolerance → matching the upper limit of the water temperature range of 40℃ and the room temperature of 20℃ (no additional heating required), which is both suitable for the body condition and does not increase energy consumption".

[0063] Lightweight optimization: Redundant computational layers in the network are removed, while core feature association learning units are retained to ensure that the convolutional neural network model is small in size and fast inference speed after training, meeting the needs of real-time parameter adjustment during bathing.

[0064] After the convolutional neural network model is trained, a target convolutional neural network model is formed. Essentially, it is a "cost-optimal parameter matcher under compliance constraints," and its logic for outputting the optimal solution perfectly aligns with the actual application scenario of a ranch, as detailed below: Parameter matching logic: After the perception and recognition module obtains the composite identity information of the current bather, the target convolutional neural network model will retrieve the corresponding patterns learned during training and select the parameter combination with the minimum "total water consumption + total energy consumption" within the parameter range of the person's work area. For example, if a zookeeper intends to enter a normal breeding area, the target convolutional neural network model, based on its historical characteristics of "high action efficiency and no low temperature intolerance," will directly output the optimal solution of "water temperature 37℃, room temperature 18℃, water flow rate 4L / min, duration 5min, and water consumption 20L." All parameters are within the compliant range of the normal breeding area, and the cost is the lowest.

[0065] Dynamic Adaptability: During the bathing process, if the real-time data transmitted by the sensing and recognition module (such as water temperature fluctuations and changes in personnel movements) deviates from the initial optimal parameters, the target convolutional neural network model will correct itself based on the learned patterns. For example, if the initial water flow rate is 4L / min, but real-time monitoring detects a decrease in personnel movement and a drop in cleaning efficiency, the target convolutional neural network model will fine-tune the water flow rate to 5L / min within the compliant range to ensure that the disinfection effect is not substandard, while avoiding cost waste or disinfection failure due to parameter rigidity.

[0066] Cost optimization is ensured: The target convolutional neural network model always aims to minimize the total water consumption and total energy consumption. By learning the strong correlation between parameters and costs in historical data, it automatically avoids high-cost parameter combinations. For example, in water temperature selection, it prioritizes matching historical preferred values ​​that do not require additional heating (e.g., when the ambient water temperature is 38℃, this temperature is directly used as the optimal water temperature, eliminating the need for energy to heat the water). In time selection, it prioritizes using the lowest time in the process library (e.g., for personnel without cheating records, the lowest time is directly matched to reduce unnecessary water consumption).

[0067] In one embodiment, although the location and posture of the bather can be used to determine that the bather is in a designated position and taking a bath, it is impossible to determine whether the bather has completed the standard bathing actions. Therefore, the personnel shower system applicable to ranches in this application further includes: Two radar sensors are positioned at an angle of 45° upwards, with their shooting ranges overlapping to capture the shower area. This allows the two radar sensors to simultaneously capture the front, back, side, and squatting movements of the person, eliminating blind spots such as "the front movement obstructs the view when the person is facing away from the radar" and "the legs cannot be recognized when squatting." The recognition coverage is improved by 30% compared to a horizontally arranged system.

[0068] The central control module is configured as follows: The position and posture information of the first bather and the second bather are synchronously transmitted to the central control module. The central control module calls the target convolutional neural network model to extract features from the position and posture information of the first bather and the second bather, respectively, to obtain the features of the first bather and the second bather. The position and posture information of the first bather and the second bather are obtained by synchronously collecting bathing status data using two radar sensors.

[0069] It should be noted that the bathing stage start signal (issued by the central control module) and the area matching instructions (ordinary breeding area / isolation area / slaughtering area) of the standardized bathing process library.

[0070] Dual radar deployment and division of labor: The first and second radar sensors are integrated on both sides of the top of the shower head housing, arranged symmetrically at a 45° angle upwards (the angle between the radar sensor's emission direction and the vertical direction is 45°). Each radar has a detection angle of ±60°, overlapping to cover the entire shower area (without blind spots). The first radar sensor focuses on collecting data from the left side of the person, while the second radar sensor focuses on collecting data from the right side, consistent with the function of the human body status sensor in the perception and recognition module.

[0071] Synchronous acquisition mechanism: Dual radar sensors start synchronously at a preset frequency, such as 0.5 seconds / time, to capture the position coordinates (X / Y / Z axes, unit cm), limb posture angles (arm bending angle, shoulder swing angle, etc., unit °), movement change frequency (unit times / second), and stillness duration (unit s) of the person in real time, forming the position and posture information of the first bather and the position and posture information of the second bather respectively.

[0072] Data preprocessing and transmission: Data collected by the dual radars is transmitted to the central control module via a wireless communication module (supporting WiFi communication) or a wired connection; the central control module timestamps the two data streams to ensure synchronous acquisition.

[0073] The synchronized location and posture information of the first bather and the second bather (both are structured data, including location coordinates, posture angle, movement frequency, and duration of stillness).

[0074] The first bather's features and the second bather's features are fused to form a fused posture feature. The fused posture feature is then compared with the standard postures in a preset standard posture library to obtain a comparison result. The standard posture library stores multiple standard postures and the duration of each posture. The standard posture library is arranged in a standardized bathing process library so that the ordinary breeding area, isolation area, and slaughtering area in the standardized bathing process library all correspond to postures in the standard posture library and the duration of each posture.

[0075] It should be noted that the synchronized position and posture information of the first bather and the second bather are respectively input into the pre-trained target convolutional neural network model.

[0076] The training data for the target convolutional neural network model comes from historical bathing data, including standard pose data from different areas and angles collected by dual radars. Before training, the raw data needs to be standardized, as shown in the following formula: ; in, Represents the standardized eigenvalues. This represents the raw data collected (such as posture angle and motion frequency). This represents the average of historical data of the same type in the same region. It represents the standard deviation of historical data of the same type in the same region, ensuring that the model focuses on learning the patterns of posture features.

[0077] The features of the first and second bathers can be extracted by calling the target convolutional neural network model through the central control module. Specifically, feature extraction is performed on the two sets of position and posture information, and the extracted features are adapted to the control algorithm of the main control chip. These features include, for example, the relative positions of key limb points (such as the distance between the hand and chest, the angle between the shoulder and back), the rate of change of movement (such as the frequency of arm swings, the speed of body rotation), and posture stability parameters (such as the percentage of time a certain posture is maintained). This yields the feature vectors of the first and second bathers, which are then fused. The fusion method can be a weighted summation of the two feature vectors. The formula is as follows: ; in, This represents the fused pose feature vector. This represents the feature vector of the first bather. This represents the feature vector of the second bather. This represents the weight of the feature vector of the first bather. This represents the weight of the feature vector of the second bather.

[0078] Standard posture library association: The standard posture library is pre-stored in the standardized bathing process library, which corresponds one-to-one with the ordinary breeding area, isolation area, and slaughtering area. Each area contains the necessary key action postures and minimum durations (e.g., ordinary breeding area: hand washing ≥60s, neck wiping ≥30s; isolation area: hand washing ≥60s, neck wiping ≥30s, back wiping ≥30s, foot rinsing ≥40s). Each posture can correspond to 3-5 core feature points (e.g., hand washing corresponds to "the relative position change frequency of the hand ≥1 time / second, and the arm bending angle 30°-90°").

[0079] Comparison and judgment: The central control module will compare the fused attitude feature vector with each standard attitude in the standard attitude library one by one to form a comparison result.

[0080] If the degree of completion of the fused posture feature and the standard posture in the comparison results is greater than or equal to the set threshold, and the duration of the fused posture feature is greater than or equal to the preset posture duration, then the bathing will ultimately meet the standard; otherwise, a warning will be given.

[0081] Specifically, the feature similarity is calculated (i.e., posture completion rate = number of matching feature dimensions / total number of feature dimensions × 100%); at the same time, the actual duration of the standard posture corresponding to the fused posture feature vector is recorded (excluding invalid durations of more than 30 seconds for a single stillness). If the completion rate of all standard postures is ≥90% and the actual duration is ≥ the corresponding minimum duration, then the bathing is considered to have met the final standard; otherwise, an alert is triggered.

[0082] Warning mechanism: When the standard is not met, the central control module will activate the voice prompt (such as "Please complete the back wiping action, which needs to be continued for 30 seconds"), touch display screen (indicating the incomplete action and the required duration), and status indicator light flashing (red) through the drive circuit, which is in line with the interactive guidance function of the intelligent sprinkler module.

[0083] The final results obtained include the bathing final compliance result (qualified / unqualified), warning instructions (when the standard is not met), and full bathing process data (including feature fusion records, comparison results, and duration data).

[0084] Finally, it should be noted that the target convolutional neural network model can be trained using historical pose data, and this application does not limit the training process. Furthermore, during feature comparison, the standard poses in the standard pose library are first labeled with feature points. Next, the standard poses are converted into feature point poses. Then, point-to-point comparisons are performed using the fused pose features to generate the comparison results.

[0085] For example, feature point modeling of standard postures (pre-operation, stored in the standard posture library), standard bathing postures in each risk area (such as "hand washing" and "neck wiping" posture samples in ordinary breeding areas), and a list of 12 core human feature points (head, left shoulder, right shoulder, left elbow, right elbow, left wrist, right wrist, hip, left knee, right knee, left ankle, right ankle).

[0086] For each standard posture (such as "hand washing"), sample data of that posture is collected by dual radars (multiple collections and averaged). The target convolutional neural network model is invoked to extract the corresponding dimensions of 12 core feature points in the sample data (e.g., "hand washing" is associated with 4 feature points: left wrist, right wrist, left elbow, and right elbow), thus obtaining the "feature point dimension set" of this standard posture (e.g., 12 dimensions: 4 feature points × 3 dimensions, position, angle, and speed). Set a quantization threshold for each feature point dimension (e.g., left wrist movement rate ≥ 1 time / second, right elbow flexion angle 30°-90°) to form "standard feature point posture data" (including feature point dimension set + quantization threshold). The "standard feature point posture data" are bound to the minimum duration of the corresponding standard posture and stored in the standard posture library of the standardized bathing process library according to the risk area classification (e.g., ordinary breeding area - hand washing: 12-dimensional standard feature point data + minimum duration of 60 seconds).

[0087] Finally, a standard pose library is bound to the feature point data (each standard pose corresponds to a unique "feature point dimension set + quantization threshold + minimum duration").

[0088] Real-time comparison: The location and attitude information of the first bather and the second bather, collected synchronously by dual radars, form real-time data.

[0089] The target convolutional neural network model is invoked to process the real-time data, extract the corresponding dimensional data of 12 core feature points, and form a "real-time feature point dimension set" (the format is consistent with the "feature point dimension set" in the standard pose library, such as 12 dimensions). According to the target standard pose of the current bathing stage (such as "hand washing"), the feature point dimensions related to the pose in the real-time data are filtered out (such as only keeping the 12-dimensional data corresponding to the left wrist, right wrist, left elbow, and right elbow), and irrelevant dimensions (such as hip and knee data) are removed.

[0090] Finally, a "real-time feature point dimension set" (e.g., 12-dimensional, in the same format as standard data) matching the target standard pose is obtained.

[0091] The real-time feature points are compared with the standard feature points, following a one-to-one dimension comparison principle. Each dimension of the real-time feature point is compared with the dimension of the standard feature point (e.g., real-time left wrist movement rate vs. standard left wrist movement rate, real-time right elbow flexion angle vs. standard right elbow flexion angle). The matching of a single dimension is determined: if the deviation between the real-time feature value and the standard feature value is ≤10% (e.g., standard rate 1 time / second, real-time 0.92 times / second, deviation 8%), then the dimension is "matched successfully"; if the deviation is >10%, then the matching fails. Finally, the number of successfully matched feature dimensions and the total number of standard feature point dimensions are obtained.

[0092] Dual compliance verification: First level: Posture completion rate ≥ 90%; Second level: The actual duration of the real-time feature point pose is greater than or equal to the minimum duration in the standard pose library (e.g., the actual duration of hand washing is 65 seconds or more than 60 seconds). Result determination: If both checks pass, the standard posture is considered complete; if either fails, it is considered incomplete, triggering an audio / screen / light warning to prompt for rework. The final result is the completion / incomplete result of a single standard posture, the warning instruction (if incomplete), and the posture completion value. Furthermore, for incomplete postures, rework is performed after the overall posture is completed.

[0093] In one embodiment, the central control module further includes a memory and a drive circuit; The memory is connected to the sensing and identification module, the central control module, the water supply and disinfection module, and the spray module respectively, and is used to store the data generated by the sensing and identification module, the central control module, the water supply and disinfection module, and the spray module during operation; The drive circuit is connected to the water supply disinfection module and the spray module respectively, and is used to send the control command to the water supply disinfection module and the spray module respectively.

[0094] Specifically, the memory adopts a dual-storage architecture of "local storage + cloud synchronization" and establishes stable connections through relevant structures, such as with the sensing and recognition module, the main control chip, the water supply and disinfection module, and the spray module.

[0095] The storage rules of the storage device can adopt a structured format for classified storage, with each data item associated with a unique timestamp and personnel identifier, facilitating rapid retrieval and traceability; the local retention period for historical ledger data can be no less than 1 year, meeting the long-term traceability requirements of biosafety audits; Data synchronization mechanism of the storage: Through the linkage interface module and the wireless communication module, key data (personnel identity, bathing standard compliance results, core parameters) are uploaded to the cloud server in real time. At the same time, it supports the periodic (such as early morning every day) batch synchronization of all historical data to ensure the consistency between local and cloud data. Data security of the storage device: It has data encryption storage function, which encrypts personnel identity information and sensitive operating parameters to prevent data leakage or tampering; it supports emergency storage in case of power failure to avoid data loss.

[0096] More specifically, the drive circuit, acting as a "signal bridge between the main control chip and the execution module," adopts an industrial-grade power amplifier circuit design. It is directly connected to the main control chip, the water supply and disinfection module, and the spray module via wires. It is responsible for converting the weak current control commands output by the main control chip into strong current drive signals to ensure accurate response of the execution module. The drive circuit can be a conventional drive circuit, and this application does not limit the specific circuit structure of the drive circuit.

[0097] For example, the central control module, as the core control unit, receives data from the sensing and identification module, generates control commands, and sends them to each execution module. It includes a main control chip, a memory, a drive circuit, and a wireless communication module (supporting WiFi communication). The main control chip has a built-in control algorithm and a standardized bathing process library. The algorithm automatically monitors and identifies optimal bathing parameters (water temperature, room temperature, water flow, bathing duration, water consumption, etc.) based on the person's identity, height, location, and individual identification. The process library includes bathing processes corresponding to different risk levels, such as ordinary breeding areas, isolation areas, and slaughtering areas (e.g., ordinary area: 3 minutes of clean water cleaning → 20 seconds of foam disinfection → 2 minutes of clean water rinsing; isolation area: 5 minutes of clean water cleaning → 2 minutes of foam disinfection → 3 minutes of clean water rinsing). The memory stores personnel information, bathing parameters, historical bathing data, and the process library, and can upload the stored data to the cloud. The drive circuit is connected to the solenoid valve group, shower head adjustment mechanism, and water supply disinfection module of the intelligent spray module to execute commands. The wireless communication module transmits data with the sensing and identification module, the spray module, and the linkage interface module.

[0098] The spray module is connected to the central control module and is used to receive the control commands and generate spray parameter commands.

[0099] The spray module includes a shower head and a solenoid valve.

[0100] A shower head, connected to the water supply line, is used to spray water onto a designated area; A solenoid valve is installed on the water supply pipeline and connected to the central control module. It is used to control the opening and closing of the water supply pipeline. The solenoid valve responds to the control command and generates a spray parameter command, wherein the spray parameter command includes the opening degree and time of the solenoid valve.

[0101] Specifically, the spray module, as the system's bathing execution terminal, responds precisely to the control commands of the central control module through the coordinated work of the shower head and the solenoid valve, generating spraying parameter commands that include the opening degree and action time of the solenoid valve, realizing multi-mode spraying operations such as clean water cleaning, foam disinfection, and clean water rinsing, adapting to the bathing needs of different risk levels in the ranch.

[0102] The shower head features a standard integrated design and is installed at the top of the shower area or against the wall (ensuring that the water flow covers the entire shower area).

[0103] As the core control component of the water supply pipeline, two sets of solenoid valves are installed (one for the clear water path and one for the foam mixing path). These are placed at branch points of the water supply pipeline (near the showerhead inlet to shorten the water flow response path) and directly connected to the drive circuit of the central control module via wires. Employing a precision-controlled proportional solenoid valve, it combines water path switching and precise flow control functions. Its specific structure and functions are as follows: The solenoid valve type and matching parameters can be a two-position three-way proportional solenoid directional valve with a working voltage of 12VDC (adapted to the power management module output) and a rated working pressure of 0.1-1.0MPa, which is suitable for the normal pressure range of the ranch water supply pipeline.

[0104] Working principle: By receiving control commands from the central control module, it can simultaneously achieve "waterway on / off switching" and "precise flow control" without the need for additional auxiliary mechanisms.

[0105] On / off control: When the solenoid valve coil is energized, the valve core switches to connect the corresponding water circuit (clean water circuit or foam mixing circuit), and when the power is off, it cuts off the water circuit, ensuring accurate switching of water circuits at each stage of the bathing process (such as connecting the clean water circuit during the cleaning stage and the foam mixing circuit during the disinfection stage).

[0106] Sprinkler parameter command generation and execution: Command reception: The solenoid valve receives control commands from the central control module through the drive circuit. The commands include three core types of information: "target water flow", "action time" and "water circuit type".

[0107] Parameter conversion: The solenoid valve has a built-in micro control unit that directly converts the "target water flow rate" into the corresponding valve core opening degree (e.g., the target flow rate of 6L / min during the isolation zone cleaning stage is converted into a precise opening degree that matches the flow rate), and converts the "action time" into the valve energization duration (e.g., the valve is continuously energized for 3 minutes during the cleaning stage of 3 minutes).

[0108] Execution feedback: After the solenoid valve performs its action, it informs the central control module of the current opening status, water circuit on / off status, and actual output flow through feedback signals to ensure that the command is executed in place; if an opening deviation or failure to open / close occurs, an alarm signal is immediately sent so that the system can handle it in a timely manner.

[0109] For example, as a shower execution unit for achieving multi-mode precise spraying, it includes a shower head housing, a shower head nozzle, and a touch display screen. The shower head features spraying, constant water temperature, adjustable modes, and adjustable flow rate, all of which can be controlled via the touch display screen. In other words, the touch display screen can connect to a central control module. Instructions generated on the touch display screen can be sent to the corresponding structure via the central control module to prioritize shower users and prevent emergencies. Furthermore, the central control module can generate corresponding instructions for the shower head's spraying, constant water temperature, adjustable modes, and adjustable flow rate. These functions can be implemented by adding appropriate conventional components as needed, and this application does not limit their operation. The solenoid valve includes a clean water solenoid valve and a flow thermometer, responding to instructions from the central control module to switch between cleaning, disinfection, and rinsing. Essentially, it uses the solenoid valve to control the on / off state and opening degree of the connected pipelines.

[0110] The water supply and disinfection module is connected to the central control module and is used to receive the control commands and generate water supply parameter commands and disinfection parameter commands.

[0111] The water supply disinfection module, as the core of the system for ensuring water supply and executing disinfection, can receive control commands from the central control module to generate disinfection parameter commands including disinfectant dosage and foam concentration. It then injects a fixed quantity and concentration of foam disinfectant into the water supply pipeline, working in conjunction with the spray module to complete the disinfection stage, ensuring that the disinfection effect meets standards and that no disinfectant is wasted. Details are as follows: The water supply disinfection module is an integrated foam generation and dispensing device, such as a conventional foam disinfection equipment. It can be installed in a concealed area on the side of the shower room (without occupying shower space). It is connected to the branch node of the water supply pipeline of the spray module through the water supply pipeline (equipped with a one-way valve to prevent water backflow), and is electrically connected to the drive circuit of the central control module through wires to receive and execute "disinfection-related control commands".

[0112] Specifically, the water supply disinfection module includes a foam disinfection device.

[0113] The foam disinfection device is connected to the central control module and the water supply pipeline respectively, and is used to inject foam disinfection water into the water supply pipeline in response to the controlled command.

[0114] It should be noted that the foam disinfection equipment receives and parses instructions as follows: It receives control instructions from the central control module via the drive circuit. These instructions include three types of information: "disinfection duration," "foam concentration," and "target flow rate" (e.g., "disinfection of the isolation area, concentration 3%, duration 2 minutes, flow rate 4 L / min"). The built-in micro-control unit (a conventional control unit, which this application should not limit) parses these instructions into specific execution parameters (e.g., a concentration of 3% corresponds to a "disinfectant:water = 1:99" ratio, and a flow rate of 4 L / min corresponds to the speed of the foaming pump and the opening of the built-in solenoid valve). Specifically, the central control module issues disinfection stage control instructions (containing only disinfection-related parameters, excluding water temperature and pressure instructions); the water supply disinfection module (foam disinfection equipment) parses the instructions, controls the opening of the built-in solenoid valve to dispense disinfectant; it injects the disinfectant into the water supply pipeline, and the spraying duration and range are controlled by the solenoid valve of the spray module; the entire process feeds back the execution status to the central control module, forming a closed loop in the disinfection process.

[0115] The linkage interface module is connected to the sensing and recognition module, the central control module, the water supply and disinfection module, and the spray module respectively, and is used to upload the data of the entire bathing process to the host computer.

[0116] The linkage interface module includes an RS485 communication interface.

[0117] An RS485 communication interface is used to transmit the entire bathing process data to a host computer, wherein the host computer includes at least a personnel management system and a biosafety management system.

[0118] The bathing process data includes at least the bather's identity information, the bathing status data, the target bathing process parameters, the bathing adjustment instructions, the water supply parameter instructions, the disinfection parameter instructions, and the spray parameter instructions.

[0119] Specifically, the linkage interface module, serving as the data transmission interface, can adopt an integrated encapsulation design and be wired to the sensing and identification module, central control module, water supply and disinfection module, and sprinkler module. It collects the working data of each module through a general I / O interface or UART interface to ensure stable and delay-free data transmission. The linkage interface module is connected to the host computer (personnel management system, biosafety management system) via an RS485 bus, supporting point-to-point and multi-point network communication, adapting to the scenario of centralized management of multiple bathing rooms in the ranch. In addition, the working data of each module can be stored in the memory, and then the linkage interface module can be used to retrieve the data in the memory and transmit it.

[0120] For example, the linkage interface module can be used to realize data linkage between the system and the pig farm personnel management system and the biosafety management system (both of which are existing systems, mentioned in this application only for ease of understanding and do not involve any improvement to the system). It adopts an RS485 communication interface to upload data such as personnel identity, bathing time, bathing duration, foam disinfection parameters, water temperature, water pressure and water consumption to the pig farm personnel management system to form a bathing compliance ledger, which is convenient for subsequent traceability and verification. At the same time, it can receive bathing process update instructions issued by the pig farm personnel management system and update the process library in the main control chip synchronously to adapt to the dynamic adjustment needs of the biosafety management system.

[0121] In summary, this application provides a personnel shower system suitable for ranches, which has the following beneficial effects: 1. Mandatory Shower Mechanism: The system combines identity recognition and access control technologies, making the shower procedure the only mandatory prerequisite for entering the production area. This completely solves the fundamental management problem of the inability to guarantee the execution rate of the shower procedure.

[0122] 2. Precise control of the use of shower gel and shampoo: Add the shower gel and shampoo in precise quantities to ensure effective use and avoid waste or insufficient use.

[0123] 3. Data traceability: Complete records of each person's bathing data to meet biosafety audit requirements.

[0124] 4. Water and energy saving: Intelligent flow control saves more than 30% of water compared to traditional bathing.

[0125] 5. Humanized design: Constant temperature water supply and voice prompts improve staff cooperation.

[0126] 6. Status indicator light settings: The color changes according to the status, making it easy to distinguish whether it is qualified or not.

[0127] like Figure 2 As shown, in a second aspect, this application provides a method for a personnel shower system suitable for ranches, applied to the aforementioned personnel shower system suitable for ranches, the method comprising: S100, obtain the identity information of bathers and bathing status data; S200, associate the bather's identity information with the work area to form target bathing process parameters; S300, based on the difference between the bathing status data and the target bathing process parameters, a control command is generated; S400, according to the control instructions, generates spray parameter instructions, water supply parameter instructions and disinfection parameter instructions respectively; S500, the bather's identity information, bathing status data, target bathing process parameters, bathing adjustment instructions, water supply parameter instructions, disinfection parameter instructions and spraying parameter instructions are combined into a full bathing process data and transmitted to the host computer.

[0128] It should be noted that a detailed explanation of the above method can be found in a description of a personnel shower system suitable for ranches, which will not be repeated here.

[0129] like Figure 3 As shown, in a third aspect, this application provides an apparatus for a personnel shower system suitable for ranches, applied to the aforementioned personnel shower system suitable for ranches, the apparatus comprising: The power management module is used for power supply; The shower head main control board is connected to the power management module and is used to carry the control chip; An external device is connected to the shower head main control board to collect the identity information of the bathers and transmit data to the shower head main control board.

[0130] The sensor assembly is connected to the main control board of the shower head and is used to collect ambient temperature information, bath water temperature information, and the position and posture information of the bather. The driving circuit is connected to the main control board of the shower head, the solenoid valve and the foam disinfection device respectively, and is used to drive the solenoid valve and the foam disinfection device to work in response to the main control board of the shower head; A network and cloud module is connected to the shower head main control board and is used to transmit data from the shower head main control board to the host computer via the network. A water system is connected to the drive circuit. The water system includes a solenoid valve and a shower head. The shower head is connected to a water supply pipe, and the solenoid valve is installed on the water supply pipe.

[0131] It should be noted that the power management module is used to supply power to the related devices, modules and systems connected to it.

[0132] The shower head control board is a conventional circuit board, and this application has not made any improvements to it.

[0133] External devices may include mechanical keyboards, touch keyboards, RFID card readers, touch display screens, and indicator lights, etc., for the implementation of corresponding functions such as reading and display.

[0134] Sensor components may include temperature sensors, water temperature sensors, radar sensors, flow meters, and hygrometers. Temperature sensors, water temperature sensors, and radar sensors have been described previously and will not be repeated here. Flow meters are installed in the water supply pipeline to detect the water flow rate and generate flow data signals that are fed back to the shower head control board. This allows the control board to understand the water consumption of the bathers and generate corresponding signals. For example, in the standardized bathing process library, the work areas corresponding to the ordinary breeding area, isolation area, and slaughtering area contain water flow data. This water flow can be detected by the flow meter and generate flow data signals, serving as reference data for issuing adjustment commands. Especially when the control algorithm has a lower limit for the water flow in the isolation area, flow matching and other actions can be performed using the flow meter to collect relevant data and generate feedback flow data signals. Hygrometers are installed in the bathing area to collect the relative humidity of the air within the bathing area. Combined with temperature, this facilitates temperature and humidity optimization in the control algorithm.

[0135] The drive circuit is connected to the shower head main control board, which houses the central control module. Control commands issued by the central control module are then transmitted via the drive circuit connected to the shower head main control board to the solenoid valves in the water supply disinfection module and the spray module, respectively. This allows for flow control of the water and disinfectant water using the opening and closing of the solenoid valves. The foam disinfection equipment is not limited to conventional foam disinfection equipment; for example, a bubble machine could be used.

[0136] The network and cloud module may include a wireless communication module and a storage device. The wireless communication module is used for data transmission, and the storage device is used to store data and upload the data to the cloud at a set time through the wireless communication module. The cloud can be a cloud platform, server, etc., and can be displayed through a mobile app connected to the cloud platform or server. It should be noted that a mobile phone can also be used as a cloud storage device.

[0137] The water system may include a T-junction and a solenoid valve. One of the T-junctions connects to the main water supply line, such as a municipal water pipe; the other connects to the overhead shower head, and a solenoid valve is installed on the water supply line between the two T-junctions and the shower head; the third connects to a bubble machine, and a solenoid valve is installed on the water supply line between the T-junction and the bubble machine. The bubble machine is connected to the overhead shower head via the water supply line. When the solenoid valve is opened, water enters the bubble machine, forming foam disinfectant. The foam disinfectant mixes with clean water in the water supply line to form a mixture, which is then sprayed out through the overhead shower head connected to the water supply line. When the solenoid valve between the three-way valve and the bubble machine is closed, and the solenoid valve between the two-way valve and the shower head is open, the water in the water supply pipe connected to the one-way valve flows out through the shower head, thus achieving the spraying of clean water from the shower head. (Heating the water in the main water circuit can be achieved by means of a heating furnace or a rapid heating wire, etc., and is a conventional structure, which is not limited in this application. For example, a heating furnace can be arranged on the main water circuit to facilitate heating the water in the main water circuit so that the water temperature in the main water circuit can reach the set temperature.)
