DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] The relevant detection scheme for identifying loading and unloading operation efficiency mainly adopts the method of deep learning, which generally includes: obtaining the shooting video sent by the camera device, wherein the shooting video contains at least one loading and unloading area; inputting the shooting video into the target detection module to obtain the detection result in the target loading and unloading area output by the target detection model; in the case where the detection result contains loading and unloading vehicles and personnel, determining the personnel information in the target loading and unloading area and the vehicle information of the loading and unloading vehicles; according to at least one of the personnel information and the vehicle information, determining the loading and unloading operation efficiency corresponding to the target loading and unloading area. However, since the loading and unloading operation is in the carriage, it is easily affected by environmental factors such as light, camera height, angle, etc., resulting in a low accuracy rate of the operation efficiency detection result. Moreover, this technical solution can only detect the number of personnel, and cannot accurately count the operation efficiency of each person.

[0018] Therefore, the present application provides a method for identifying loading and unloading operation efficiency, which can improve the accuracy of identifying loading and unloading operation efficiency, and is low-cost and easy to operate. The method is applied to a loading and unloading operation efficiency identification device, which includes a control module 101, a detection module 102 connected to the control module 101, a timing module 103 connected to the control module 101, and a power supply module 104 for power supply. The structure of the loading and unloading operation efficiency identification device is as follows: Figure 1 The power supply module 104 is used to supply power to each module in the device, and the power supply module 104 may be a power source.

[0019] The detection module 102 is worn by the target object. The detection module 102 includes at least one vital sign recognition submodule 1021, at least one positioning detection submodule 1022 and at least one motion detection submodule 1023. The vital sign recognition submodule 1021 is used to obtain the vital sign parameters of the target object, the positioning detection submodule 1022 is used to obtain the target distance between the target object and the target vehicle, and the motion detection submodule 1023 is used to obtain the motion parameters of the target object. The target object is an object performing loading and unloading operations on the target vehicle. The target object may wear the detection module 102. If the detection module 102, the control module 101, the timing module 103 and the power supply module 104 are integrated in one device, the device can be worn by the target object. The specific method for identifying the efficiency of loading and unloading operations is as follows: Figure 2 As shown, the method comprises the following steps: Step 201: the vital sign recognition submodule obtains vital sign parameters of the target object in response to the first target instruction, the positioning detection submodule obtains the target distance between the target object and the target vehicle in response to the first target instruction, and the motion detection submodule obtains motion parameters of the target object in response to the first target instruction; Specifically, the main task of the vital sign recognition submodule is to obtain and identify the vital sign parameters of the target object. After receiving the first target instruction, the vital sign recognition submodule is started, and the vital sign data such as body temperature and heart rate of the target object are obtained by using a temperature sensor and a heart rate detection sensor. The main task of the positioning detection submodule is to obtain the target distance between the target object and the target vehicle. After receiving the first target instruction, the positioning detection submodule can use a positioning sensor or an ultrasonic sensor to measure the distance between the target object and the target vehicle. The main task of the motion detection submodule is to obtain the motion parameters of the target object. After receiving the first target instruction, the motion detection submodule detects the moving speed and / or moving frequency of the target object through a speed sensor or a gyroscope. For example, it can be the moving speed and / or moving frequency of the target object's legs, or it can be the moving speed and / or moving frequency of the target object's hands.

[0020] Step 202: The control module determines whether the target object is in a preset state based on the vital sign parameters, the target distance, and the motion parameters; if the target object is in the preset state, the timing module stops timing, and if the target object is not in the preset state during the process of the timing module stopping timing, the timing module starts timing; Specifically, the control module is responsible for analyzing the parameters collected from the submodules of each detection module and making judgments based on these parameters. Among them, the data such as the body temperature and heart rate of the target object obtained by the vital signs recognition submodule; the data of the distance between the target object and the loading and unloading vehicle obtained by the positioning detection submodule; the moving speed and / or moving frequency data of the target object obtained by the motion detection submodule. The control module can evaluate these data according to a preset threshold to determine whether the target object is in a preset state. If the target object is in the preset state, the timing module stops timing; if the target object is not in the preset state, the timing module starts timing. It should be noted that the preset state may refer to a state in which the loading and unloading efficiency is low or no loading and unloading work is performed.

[0021] Step 203: the vital sign recognition submodule, the positioning detection submodule, and the motion detection submodule shut down in response to the second target instruction, and the timing module sends the timing result to the control module; Specifically, when the control module sends the second target instruction, it means that the data collection phase is over and data analysis and evaluation are required. After receiving the second target instruction, the vital sign submodule stops detecting the vital sign parameters of the target object, such as body temperature, heart rate, etc.; the positioning detection submodule stops detecting the distance between the target object and the target vehicle; the motion detection submodule stops detecting the moving speed and / or moving frequency of the target object. After receiving the second target instruction, the timing module sends the recorded timing results to the control module. The recorded timing results include the total operating time and the effective working time that is not in the preset state.

[0022] Step 204: The control module identifies the efficiency of the target object loading and unloading operation based on the timing results.

[0023] Specifically, the control module is responsible for processing the timing results and determining the loading and unloading efficiency of the target object. Exemplarily, the control module can determine whether the loading and unloading efficiency of the target object is high or low by comparing the timing results with the set timing time. Exemplarily, the timing results can include total operating time and effective working time. The effective working time can be the time when the target object is not in a preset state and actually performs loading and unloading work. The total operating time is the time from the start to the end of the loading and unloading work. The control module calculates the ratio of the effective working time to the total operating time, and this ratio can reflect the working efficiency of the target object.

[0024] In this embodiment, the method is applied to a loading and unloading operation efficiency identification device, which includes a control module, a detection module, a timing module and a power supply module. The detection module is worn by the target object and includes a vital sign recognition submodule, a positioning detection submodule and a motion detection submodule, which are respectively used to obtain the vital sign parameters of the target object, the distance from the target vehicle and the motion parameters. Specifically, each submodule responds to the first target instruction to obtain the corresponding parameters; the control module determines whether the target object is in a preset working state based on these parameters to control the start and stop of the timing module; each submodule responds to the second target instruction to stop working, and the timing module sends the result to the control module; the control module identifies the loading and unloading operation efficiency of the target object according to the timing result. Based on the detection module worn by the target object, the method realizes the identification of the effective working time of the target object during the loading and unloading operation by using the target object's vital sign recognition technology, positioning technology, and motion information collection technology, and combining the control module and the timing module, and can accurately obtain the specific target object's operation efficiency, and the cost is low and easy to operate.

[0025] In one embodiment, the control module includes a first control module and a second control module, and at least the second control module and the detection module are installed together; Among them, the first control module sends the first target instruction and the second target instruction to the detection module, and the first control module identifies the efficiency of the loading and unloading operation of the target object based on the timing results; the second control module determines whether the target object is in a preset state based on vital sign parameters, target distance and motion parameters.

[0026] Specifically, the first control module is responsible for sending the first target instruction and the second target instruction to the detection module, and identifying the loading and unloading efficiency of the target object based on the timing results. The first control module sends two types of instructions to the detection module: the first target instruction can refer to the start instruction to trigger the detection module to start working, including the vital sign recognition submodule, the positioning detection submodule and the motion detection submodule to collect relevant parameters; the second target instruction can refer to the end instruction to instruct the detection module to stop working. The first control module receives the timing results sent by the timing module, and analyzes the loading and unloading efficiency of the target object based on these results.

[0027] The second control module is installed together with the detection module, and specifically can also be integrated on the same chip, and is responsible for real-time processing of the data collected from the detection module and determining whether the target object is in a preset working state. The second control module analyzes the data collected from the vital signs recognition submodule, the positioning detection submodule and the motion detection submodule to determine whether the target object is in a preset working state. This may include checking whether the vital signs of the target object meet the normal human body sign parameters, whether the target object is in the correct working area, and whether the movement speed of the target object meets the requirements of the loading and unloading operation. Among them, the second control module is installed together with the detection module, on the one hand, it can reduce the time delay of data processing and improve the response speed of the device. On the other hand, after the second control module is installed together with the detection module, it is worn by the target object. The first control module is responsible for sending start and end instructions and receiving timing results, and then the first control module can be a controller integrated on the management platform, or it can be a management platform or a management server. Exemplarily, the first control module is a server, and the first control module can send start or end instructions to the detection modules on multiple target objects at the same time, or the first control module receives the timing results corresponding to multiple target objects, so as to facilitate the first control module to identify the efficiency of the loading and unloading operations of multiple target objects based on multiple timing results.

[0028] In one embodiment, the first control module is a server; the loading and unloading operation efficiency identification device further includes a communication module connected to the first control module; The first target instruction and the second target instruction sent by the first control module are both transmitted to the detection module through the communication module, and the timing result sent by the timing module is transmitted to the first control module through the communication module.

[0029] Specifically, the first control module is a server responsible for sending instructions and receiving data. The server sends two types of instructions to the detection module. The first target instruction is used to start the submodule of the detection module, so that the submodule of the detection module starts to detect vital sign parameters, target distance and motion parameters; the second target instruction is used to instruct the detection module to stop detection and instruct the timing module to send the timing result. The communication module serves as a bridge for data transmission, connecting the server and the detection module. The server transmits the first target instruction and the second target instruction to the detection module through the communication module. The timing module transmits the timing result back to the server through the communication module. It should be noted that the communication module can be a communicator, and the communicator includes a signal transmitter and a signal receiver, and the signal receiver can be responsible for completing the signal transmission and reception tasks of the communication module.

[0030] In this embodiment, the server serves as the first control module, and a communication module connects the server and the detection module. The method sends the first target instruction and the second target instruction to the detection module through the server, starts and stops the data collection process, and the timing module transmits the timing result back to the server through the communication module. The method realizes remote monitoring and data collection of loading and unloading efficiency, and improves the flexibility and response speed of the device.

[0031] In one embodiment, the first control module sends the positioning information of the target vehicle to the positioning detection submodule within the associated time period of sending the first target instruction to the detection module; wherein the associated time period is a time interval, the center point time of the time interval is the time when the first control module sends the first target instruction, and the difference between the two end points of the time interval is less than the set time threshold.

[0032] Specifically, the associated time period is a specific time interval, and its "center point time" is the moment when the first control module (server) sends the first target instruction. The difference between the two end points of the time interval is less than a preset time threshold, which means that the time interval is relatively short, so as to ensure that the sending of the first target instruction and the target vehicle positioning information are closely related in time, that is, after sending the first target instruction, the first control module also sends the positioning information of the target vehicle to the positioning detection submodule almost at the same time.

[0033] In this embodiment, the first target instruction is sent to the detection module and the positioning information of the target vehicle is sent to the positioning detection submodule. This associated time period is defined as a time interval, the center point of which is the moment when the first control module sends the first target instruction, and the time difference between the two end points of the time interval is less than a set time threshold, ensuring that the sending of the instruction and the information is closely connected in time. This method improves the synchronization of device operation and the accuracy of data, and reduces the risk of outdated positioning data due to time delay.

[0034] For example, another structural diagram of the loading and unloading operation efficiency identification device is as follows: Figure 3 As shown, the control module 101 in the loading and unloading operation efficiency identification device includes a first control module 1011 and a second control module 1012. The communication module 105 connects the first control module 1011 and the detection module 102, and the second control module 1012 and the detection module 102 are installed together. The second control module 1012 determines whether the target object is in a preset state based on vital sign parameters, target distance and motion parameters. It should be noted that the detection module 102 includes a vital sign identification submodule 1021, a positioning detection submodule 1022 and a motion detection submodule 1023, and the device also includes a power supply module 104 and a timing module 103.

[0035] In one embodiment, another structural diagram of the loading and unloading operation efficiency identification device can also be as follows: Figure 4 As shown, the first control module in the control module of the loading and unloading operation efficiency recognition device may be a server 4011, and the second control module may be a controller 4012. The vital sign recognition submodule in the detection module may be a body temperature sensor 4021, the positioning detection submodule may be a positioning sensor 4022, and the motion detection submodule may be a speed sensor 4023. The timing module may be a timer 403. The power supply module may be a power supply 404. The communication module may be a communicator 405, including a signal transmitter 4051 and a signal receiver 4052.

[0036] In one embodiment, the motion parameter of the target object includes the moving speed of the target object; wherein the motion detection submodule includes a speed detection submodule, and the speed detection submodule includes at least one speed sensor.

[0037] Specifically, the moving speed refers to the speed at which the target object moves during the loading and unloading operation. This parameter is crucial for evaluating work efficiency because the moving speed can reflect the activity level and work rhythm of the target object. The speed detection submodule is a component of the motion detection submodule and is specifically responsible for detecting the moving speed of the target object. The speed detection submodule includes at least one speed sensor that can measure the moving speed of the target object.

[0038] In this embodiment, the speed detection submodule can detect the moving speed of the target object in real time through the data collected by the speed sensor, and transmit the data to the control module for further analysis. This method can accurately measure the dynamic performance of the target object in loading and unloading operations, and provide the control module with key motion parameter information so as to accurately evaluate the working efficiency of the target object.

[0039] In one embodiment, the device is worn on the wrist of the target object, and the moving speed of the target object is the moving speed of the target object's hand.

[0040] Specifically, by wearing the device on the wrist, the movement speed of the hand can be directly detected. The device here can be a detection module, or a device composed of a detection module, a communication module, a timing module and a power supply module. The hand movement speed is a key indicator of loading and unloading operations because it is directly related to the execution speed and efficiency of the operation. The device includes at least one speed sensor specifically used to detect the movement speed of the hand and / or wrist.

[0041] In this embodiment, the device includes a speed sensor that can capture the movement speed of the target object's hand in real time and transmit the data to the control module for analysis. By wearing the device on the wrist, the device can directly and accurately measure the hand movement, thereby obtaining the movement speed data of the target object. The device can improve the accuracy of detection and make the evaluation of work efficiency more accurate.

[0042] In one embodiment, the vital sign parameter of the target object includes the body temperature of the target object, the vital sign recognition submodule includes a body temperature detection submodule, and the body temperature detection submodule includes at least one body temperature sensor.

[0043] Specifically, body temperature is used as one of the vital sign parameters. During loading and unloading operations, the temperature can be detected to determine whether the target object is moving due to loading and unloading operations, so as to avoid misjudging the movement of other objects as the movement of the target object. The body temperature detection submodule is a component of the vital sign recognition submodule, which is specifically responsible for detecting the body temperature of the target object. The body temperature detection submodule includes at least one body temperature sensor for measuring the body temperature of the target object in real time.

[0044] In this embodiment, the temperature of the target object is detected as part of the vital sign parameters by integrating the temperature detection submodule into the vital sign recognition submodule. The temperature detection submodule includes at least one temperature sensor for collecting the temperature data of the target object in real time and transmitting the data to the control module for analysis. This method can reduce misjudgment by detecting the temperature in real time, and is low-cost and easy to implement.

[0045] In one embodiment, Figure 5 As shown, the control module determines whether the target object is in a preset state based on the vital sign parameters, the target distance and the motion parameters, including the following steps: Step 501: The control module determines whether the body temperature meets a first condition, where the first condition is: the body temperature is less than a first temperature threshold or greater than a second temperature threshold; Specifically, a lower limit value of body temperature can be set as a first temperature threshold, which is usually a lower limit based on the normal human body temperature range; an upper limit value of body temperature can be set as a second temperature threshold, which is usually a higher limit based on the normal human body temperature range. The control module receives data from the body temperature detection submodule, that is, the real-time body temperature readings of the target object. The control module compares these readings with the preset first and second temperature thresholds to determine whether the body temperature of the target object is within the normal range.

[0046] Step 502: The control module determines whether the moving speed meets the second condition, the second condition being: the moving speed is less than a speed threshold; Specifically, a lower limit value of the moving speed is set, called the speed threshold, and the speed threshold is used to distinguish whether the target object is working with a certain efficiency. The control module receives data from the speed detection submodule, that is, the hand movement speed of the target object. The control module compares these real-time speed readings with the preset speed threshold to determine whether the hand movement speed of the target object meets the working requirements. If the hand movement speed of the target object does not meet the second condition (i.e., less than the speed threshold), the control module determines that the target object is in the preset working state; if the hand movement speed of the target object meets the second condition (i.e., greater than the speed threshold), the control module determines that the target object is not in the preset working state.

[0047] Step 503: The control module determines whether the target distance satisfies a third condition, where the third condition is: the target distance is greater than a distance threshold; Specifically, an upper limit value of the target distance is set, which is called the distance threshold. The distance threshold is used to distinguish whether the target object is in the effective working area. The control module receives data from the positioning detection submodule, that is, the actual distance between the target object and the target vehicle. The control module compares these real-time distances with the preset distance threshold to determine whether the target object is in the specified working area. If the distance between the target object and the target vehicle is greater than the distance threshold, it may indicate that the target object is not in the effective working area of ​​the loading and unloading operation. The target distance satisfies the third condition (i.e., greater than the distance threshold), and the control module determines that the target object is in the preset state. If the distance between the target object and the target vehicle is less than the distance threshold, it may indicate that the target object is in the effective working area of ​​the loading and unloading operation. The target distance does not meet the third condition (i.e., less than the distance threshold), and the control module determines that the target object is not in the preset state.

[0048] Step 504: If at least one of the first condition, the second condition and the third condition is met, the target object is in a preset state.

[0049] Specifically, the first condition is that the body temperature is less than the first temperature threshold or greater than the second temperature threshold; the second condition is that the moving speed is less than the speed threshold; the third condition is that the target distance is greater than the distance threshold. The control module will comprehensively consider the above three conditions to determine whether the target object is in a preset working state. If the target object meets at least one of the three conditions, it is considered that the target object is in a preset working state.

[0050] In this embodiment, the control module determines whether the body temperature of the target object is lower than the first temperature threshold or higher than the second temperature threshold (first condition); determines whether the hand movement speed of the target object is lower than the speed threshold (second condition); and determines whether the distance between the target object and the target vehicle exceeds the distance threshold (third condition). If the target object meets at least one of the three conditions, it is considered to be in a preset state, and no timing is performed in the preset state; if the target object does not meet any of the three conditions, it is considered that the target object is not in the preset state, and timing begins. This method can more accurately measure the actual working time of the target object by distinguishing whether the target object is in the preset state.

[0051] In one embodiment, the detection module starts working to obtain various parameters in response to the first target instruction, and the control module determines whether the first, second and third conditions are met through the various parameters to determine whether the target object is in a preset state to turn on or off the timing. The specific steps can be represented by a flowchart, such as Figure 6 As shown. The following steps are included: Step 601: Loading and unloading begins; Step 602: The control module sends a first target instruction to the detection module; Step 603: The detection module receives a first target instruction; Step 604: the detection module starts working; Step 605: the vital sign recognition submodule senses the body temperature of the target object; Step 606: The positioning detection submodule senses the distance between the target object and the target vehicle; Step 607: The motion detection submodule senses the hand movement speed of the target object; Step 608: The control module determines whether the target object's body temperature is less than a first temperature threshold or greater than a second temperature threshold; whether the hand movement speed is less than a speed threshold; and whether the target distance is greater than a distance threshold. Step 609: If (as long as one of the body temperature, hand movement speed and target distance does not meet the threshold limit), the timer is turned off; Step 610: If not (body temperature, hand movement speed and target distance all meet the threshold limits), then the timing starts.

[0052] In one embodiment, Figure 7 As shown, the control module identifies the efficiency of the target object loading and unloading operation based on the timing results, including the following steps: Step 701: The first control module determines a first time for sending a first target instruction and a second time for sending a second target instruction, and determines a target operation time based on a difference between the first time and the second time; Specifically, the first control module records the specific time point when the first target instruction is sent, that is, the first time. The first target instruction is usually used to start the data detection function of the detection module, such as starting to detect the vital signs parameters, target distance and motion parameters of the target object. The first control module records the specific time point when the second target instruction is sent, that is, the second time. The second target instruction is usually used to end the data detection function of the detection module and instruct the timing module to send the timing result. The first control module calculates the time difference between the first time and the second time. This time difference represents the total duration from the start of detection to the end of detection, which is the target operation time.

[0053] Step 702: The first control module identifies the efficiency of the target object loading and unloading operation based on the timing result and the target operation time.

[0054] Specifically, this is data collected from the timing module, recording the actual working time of the target object in a specific operation. The target operation time is the time determined in step 701, that is, the time difference between sending the first target instruction and sending the second target instruction, representing the total time the target object should work. The first control module compares the actual working time with the target operation time to calculate the work efficiency of the target object. The ratio of the actual working time to the target operation time can be used to determine the work efficiency of the target object.

[0055] In this embodiment, the first control module records the first time of sending the first target instruction and the second time of sending the second target instruction, and calculates the difference between the two time points to determine the target operating time. The first control module combines the timing results and the target operating time to evaluate the loading and unloading efficiency of the target object, that is, the efficiency is identified by calculating the ratio of the actual working time to the target operating time.

[0056] In one embodiment, after loading and unloading, the vital sign recognition submodule, the positioning detection submodule and the motion detection submodule in the detection module shut down in response to the second target instruction, and the timing module sends the timing result to the control module to determine the working efficiency of the target object by the ratio of the actual working time to the target working time, which can be represented by a flow chart, as shown in FIG. Figure 8 As shown. The following steps are included: Step 801: loading and unloading is completed; Step 802: The control module sends a second target instruction to the detection module; Step 803: The detection module receives a second target instruction; Step 804: the detection module stops working; Step 805: The timing module sends the timing result to the control module; Step 806: The control module identifies the efficiency of the target object loading and unloading operation based on the timing results.
