Description

Technical Field

[0001] The present invention relates to the technical field of early childhood education, and particularly relates to a device and method for recording children's social behaviors. Background Art

[0002] In the kindergarten scenario, social interaction problems among children are relatively common. Some children have the phenomenon of snatching toys, lack the awareness of sharing, and often have conflicts and crying because of this. Some children are timid and introverted, always staying alone silently in group activities and not daring to actively communicate and interact with other children. There are also some children who are too domineering and like to dominate the game process without considering the feelings of others. These problems will affect the development of children's social skills and are also not conducive to creating a harmonious atmosphere in the class. Teachers need to help children learn to get along friendly and cooperate and share through means such as guiding education and organizing cooperative activities to improve their social interaction ability. In the actual teaching process, teachers have a large number of administrative tasks to complete daily and cannot pay attention to the social interaction situation of each child in real time, let alone understand the long-term social interaction performance of children, so as to take relevant management and intervention measures to help children solve related problems. Therefore, we urgently need a means to understand the social behavior performance of a certain child. Summary of the Invention

[0003] The present invention provides a device and method for recording children's social behaviors, which collect relevant position data between students through wearable devices and analyze students' social behaviors through algorithms.

[0004] In order to achieve the above-mentioned invention purpose, the present invention adopts the following technical solutions: A device for recording children's social behaviors includes a controller and a storage module, as well as an acceleration sensor, a wireless transceiver module, a low-frequency transmitting module, a low-frequency receiving module, a battery and a power management module connected to the controller and the storage module; The controller and the storage module realize the logical control and timing processing of the device, including data acquisition, data processing, data storage and transceiver management; The battery and the power management module realize the power supply management of the device; The wireless transceiver module realizes the data transmission between the device and the cloud platform; The acceleration sensor realizes the monitoring of the wearer's motion state; The low-frequency transmitting module periodically broadcasts low-frequency signals within a certain range around it, and the low-frequency transmitting module has the control and adjustment of various transmitting powers and periods; The low-frequency receiving module monitors whether there is a low-frequency signal around it, and the low-frequency receiving module can filter the low-frequency signal data of the device itself or temporarily turn off the receiving function of the low-frequency receiving module when the device emits low-frequency signals; Preferably, the recording device is a wearable device.

[0005] Preferably, the wearable device includes a bracelet, a watch, a badge, and implanted devices such as clothes, hats, and schoolbags.

[0006] Based on the above recording device, the present invention also provides a method for recording children's social behaviors, including the following steps: S1: Bind the recording device to the student, and the binding information includes the ID of the recording device and the student's identity information; S2: Set the social range of the recording device to be the same as the signal range emitted by the low-frequency emission module, and set the effective emission interval time T1 of the low-frequency emission module; S3: Start the low-frequency receiving module to make the recording device in a listening state, and receive the low-frequency signals within the social range in real time. The low-frequency signals include the ID of the recording device worn by the corresponding student; S4: Set the minimum effective social time T2, T2 >= T1, and T2 is an integer multiple of T1. If the set value of T2 is not an integer multiple of T1, it will automatically return according to the closest integer multiple and inform the user of the actual value of T2; S5: The recording device counts the number of times N1 that the low-frequency signals of the same other recording device are not continuously received, N1 = T2 / T1. When N1*T1 > T2, it is considered that this interaction ends, and the interaction duration is recorded as T3; S6: The recording device transmits the data to the cloud platform through the wireless transceiver module. The cloud platform processes the data, calculates the social index and loneliness index of the student, analyzes the social behavior of the student through the social index and loneliness index, and presents the results to the user.

[0007] Preferably, the student's identity information in step S1 includes the ID card number, student number, class, and name.

[0008] Preferably, when step S5 records the number of times N1 of not receiving the low-frequency signal, a certain number of times of not receiving the low-frequency signal in the middle are allowed. When the low-frequency signal is received again later, a compensation for the number of times is performed; Preferably, the algorithm for the social index in step S6 is S = T4 / Ta * 100%, where T4 is the sum of T3 for each other student by this student, and Ta is the monitoring duration of this student.

[0009] Preferably, the algorithm for the loneliness index in step S6 is L = T5 / Ta * 100%, where T5 is the sum of the time when this student does not receive the low-frequency signals of any other students within a time exceeding T2, and Ta is the monitoring duration of this student.

[0010] Preferably, within a certain period of time, if there is no significant change in the low-frequency signals in the recording devices of kindergartens throughout the class within the set time threshold range, it is considered that the students are engaged in group activities, and the data during this period is not used as the time period for social analysis.

[0011] A recording device and method for children's social behavior provided by the present invention determine whether there are other children around each child and the length of time of continuous close contact by collecting the change of position data between children, so as to judge their social relationships, thereby facilitating teachers and parents to understand the social behavior habits of each child, and facilitating parents and teachers to intervene in a targeted manner in a timely manner and help children improve their character defects. Detailed implementation manners

[0012] The present invention will be further described below in conjunction with embodiments: Embodiment

[0013] 1: Device binding: In the software platform, the ID of the recording device is associated with the student number, and this student number serves as the unique identity identifier of the student in the school. At the same time, the student information also includes: ID card number, family information, age, gender, class information, etc.

[0014] 2: Set the induction range of the low-frequency emission signal of the recording device to 1m, which is consistent with the required social range of 1m in the platform. At the same time, set the emission interval of the low-frequency signal to 1 second. That is to say, this recording device emits a 1m low-frequency signal every second when emitting the induction signal, and the low-frequency receiving device is always in a state of listening to the surrounding low-frequency signals.

[0015] 3: The low-frequency emission signal of the recording device contains the ID of this device (the platform will match the corresponding student's identity information according to this ID information) 4: Set the effective social time as T2 = 30 seconds, where T1 = 1 second, then N1 = T2 / T1 = 30. When two recording devices have low-frequency induction interaction, the listening device listens at the frequency of T1. As long as the recording device does not continuously exceed 30 times (N1) without receiving low-frequency signals, it is still considered that the continuous recording duration is valid. Assume that the recording device records 50 times, then T3 = 50 seconds.

[0016] 5: Assume that a child's T3 values relative to other children are accumulated to 25 minutes within the entire activity time of 30 minutes (Ta) (if multiple low-frequency signals are sensed within the same time, only count the longest duration once). Then the social index S of this child is S = 25 / 30 * 100% = 83.33%. The loneliness index is: L = (30 - 25) / 30 * 100% = 16.67%.

[0017] Embodiment 2

[0018] 1: Device Binding: In the software platform, the ID of the recording device is associated with the student ID number, which serves as the unique identity identifier of the student within the school. At the same time, the student information also includes: ID card number, family information, age, gender, class information, etc.

[0019] 2: Set the induction range of the low-frequency emission signal of the recording device to 1m, which is consistent with the required social range of 1m in the platform. At the same time, set the emission interval of the low-frequency signal to 1 second. That is to say, the recording device emits a low-frequency signal of 1m every second when emitting the induction signal, and the low-frequency receiving device is always in a state of listening for surrounding low-frequency signals.

[0020] 3: The low-frequency emission signal of the recording device contains the ID of the device (the platform will follow up the ID information to match the corresponding student's identity information). 4: Set the effective social time as T2 = 30 seconds, where T1 = 1 second, then N1 = T2 / T1 = 30. When two recording devices interact through low-frequency induction, the listening device listens at the frequency of T1. As long as the recording device does not receive the low-frequency signal continuously more than 30 times (N1), it is still considered that the recording of the effective duration continues. Assume that after the recording device records 50 times, it does not receive the low-frequency signal more than 30 times (N1), and the compensation times are 30 times, then T3 = 50 seconds.

[0021] 5: Assume that within the entire activity time of 30 minutes (Ta) of a child relative to other children, the accumulated T3 values relative to all other children are 25 minutes (if multiple low-frequency signals are sensed within the same time, only count the longest duration once). Then the social index of this child is S = 25 / 30 * 100% = 83.33%. The loneliness index is: L = (30 - 25) / 30 * 100% = 16.67%.

[0022] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
