Description

Technical Field

[0001] The present invention relates to the field of intelligent identification technology, and in particular to a system and method for contactless child transportation for preventing infection. Background Art

[0002] For children in lower grades and kindergartens who are not able to go home independently after school, it is inevitable that parents need to pick them up from school (kindergarten) after school, and teachers must confirm whether they are the parents of the student before they can safely hand the student over to the parents. At present, most of the domestic pick-up and drop-off systems for lower grades and kindergartens require teachers to meet with parents face to face outside the classroom, and then hand the children over to the parents after confirmation; there are also parents who enter the school (kindergarten) with a card, and meet with the children in the entire class in the classroom to confirm their children, but the school (kindergarten) cannot grasp the pick-up and drop-off situation of the entire school (kindergarten) in real time. At the same time, teachers are in contact with all parents. In the case of the prevalence of various infectious diseases, multi-person contact is the fastest way for infectious diseases to spread.

[0003] In the current situation where various infectious diseases are changing and breaking out (such as mycoplasma pneumonia and influenza A in 2023), avoiding contact with multiple people as much as possible is the most effective measure to control infectious diseases. Therefore, realizing contactless pick-up and drop-off of students and reducing the spread of diseases is an urgent problem to be solved. This can not only avoid the problem of students coming into contact with multiple people and being infected, but also save parents' time in picking up their children, complete efficient pick-up and drop-off, and reduce the difficulty of teachers' supervision.

If the card swiping information of the two matches successfully, the central controller sends a gate opening signal to the motor control module to control the opening of the revolving gate; the motor rotates the revolving gate to open for 5 seconds, and only one student can pass through. After the student passes, the revolving gate is automatically closed, and the waiting information of the student's parents is automatically cancelled on the mobile phone or tablet of the management teacher, indicating that the parent has picked up his child; after the revolving gate is closed, the display screen displays the latest number of parents waiting, and the GSM module generates a new prompt information and sends it to the management teacher terminal; based on the latest number of parents waiting, it is judged whether the number of students to be picked up is 0. If the judgment result is no, the next waiting parent card swiping information is obtained, and the step S3 is returned; otherwise, it ends. The present invention effectively avoids pick-up and drop-off congestion, reduces the basic infection probability of mixed crowds, and can help management teachers better supervise students entering (leaving) school and ensure students' safety.

[0029] Based on the second aspect, further, it also includes:

[0030] When the judgment result of the card swiping information is that the student swiped the card or the parent swiped the card information does not match the student swiped card information, the central controller generates and sends an alarm signal to the alarm module to turn on the buzzer to alarm.

[0075] In addition, when encountering special circumstances, such as: some students do not come to school (kindergarten) for various reasons, but their parents go to school (kindergarten) to swipe their cards, the terminal of the management teacher receives the card swiping information of the parents' IC card and uses the terminal to send a control signal, and the display module 300 displays the information prompt that the student has not come to school (kindergarten); or after the pick-up time specified by the school (kindergarten), there are still individual students whose parents do not come to the school (kindergarten) to swipe their cards for pick-up, the school (kindergarten) will manually open the turnstile at a unified time to release these students to achieve unified management.

[0076] The present invention is used to realize non-contact picking up and dropping off of students between parents and teachers, thereby preventing the spread of diseases. First, the system is initialized, and the alarm duration and fault number are preset; the alarm duration can be set to 10 seconds as required, and the alarm duration can be modified at any time as needed; then the card swiping information is obtained, and the card swiping person is judged to be a student or a parent based on the card swiping information, and a judgment result is generated. If the judgment result is that the parent swipes the card, the display screen displays and updates the current number of parents waiting, and the GSM module 500 generates a prompt message and sends it to the management teacher terminal; if the parent holds the parent IC card and has not swiped the card on the parent card swiping module, the student holds the student IC card and swipes the card on the student card swiping module first, then the buzzer will alarm for 10 seconds through the alarm module 200, and the alarm will be automatically canceled after 10 seconds, or the alarm signal can be manually canceled; when the parent who has arrived at the school swipes the card on the parent card swiping module of the device with the parent IC card, the display module 300 will display and update the number of parents waiting in real time, and the management teacher's terminal will receive a prompt message. The management teacher is the head teacher or other subject teacher, and the head teacher's terminal is notified first. If the central controller 600 does not receive the corresponding student's card swiping information within the preset time, the second management teacher in priority is notified. The terminal of the teacher, which is a mobile phone or tablet device, receives a text message or phone prompt, such as: "NO1 Parent is waiting - the location information of the parent", at this time the management teacher can let the student to be picked up by the parent swipe the student IC card on the student card swiping module of the device; based on the prompt information, the parent's card swiping location is obtained, and when the student swipes the card at the same location, the parent's card swiping information is matched with the student's card swiping information. If the card swiping information of the two matches successfully, the central controller 600 sends a gate opening signal to the motor control module to control the opening of the revolving gate; the motor rotates the revolving gate to open for 5 seconds, and only one student can pass through. After the student passes, the revolving gate is automatically closed, and the waiting information of the student's parent is automatically cancelled on the mobile phone or tablet of the management teacher, indicating that the parent has picked up his child; after the revolving gate is closed, the display screen displays the latest number of parents waiting, and the GSM module 500 generates a new prompt information and sends it to the management teacher terminal; based on the latest number of parents waiting, it is determined whether the number of students to be picked up is 0. If the judgment result is no, the next waiting parent card swiping information is obtained, and the step S3 is returned; otherwise, it ends. The present invention effectively avoids pick-up and drop-off congestion, reduces the basic infection probability of mixed crowds, and can help management teachers better supervise students entering (leaving) school and ensure students' safety.
