Description

Technical Field

[0001] The invention relates to the technical field of library equipment, in particular to an intelligent seat occupancy prevention and cleaning device for a library. Background Art

[0002] University libraries have the advantages of quiet and comfortable learning environment, quick and convenient information query, and dedicated management, making them the preferred learning place for many students. However, with the expansion of colleges and universities and the continuous increase in the number of students, the problem of seat occupancy in university libraries has become increasingly prominent.

[0003] The so-called seat occupation refers to students placing items on seats to indicate that the seats are occupied, thereby achieving the purpose of occupying seats. Colleges and universities have taken corresponding management measures for the seat occupation problem, and the current approach is basically to solve the seat occupation problem through manual inspections. Not only is it time-consuming and labor-intensive, but it is also difficult for managers to determine whether the empty seats where items are placed are temporarily left by students or occupied, which can easily cause contradictions and even conflicts between students and managers, affecting the image of university libraries. At present, libraries are in urgent need of a device that can solve the problem of seat occupation in libraries from a technical level, improve the utilization rate of libraries, and achieve fair sharing of public resources. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent anti-seat occupation and cleaning device for libraries, which has the function of accurately and quickly locating vacant seat information, can effectively solve the current seat occupation phenomenon in university libraries, and make better use of the library's public seat resources.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0006] An intelligent anti-occupancy and cleaning device for a library comprises an intelligent folding chair, a hydraulic lifting table, and a seat reading machine. The intelligent folding chair and the hydraulic lifting table are placed in a reading room of the library in a one-to-one correspondence, and the seat reading machine is fixed on the wall at the entrance of the library.

[0007] The intelligent folding chair comprises a backrest, a battery box, a hydraulic lifting rod, a seat wheel, a pan platform, and a power system. The backrest can be folded automatically. A battery box is arranged below the seat surface of the folding chair, and batteries are placed in the battery box. A hydraulic lifting rod is arranged below the battery box, and a folding chair base is arranged below the hydraulic lifting rod. An upright pan platform is arranged on the folding chair base, and five chair legs are arranged under the folding chair base. A seat wheel is arranged at the lower end of each chair leg, wherein the front seat wheel is connected to the motor drive shaft of the folding chair power system and serves as a driving wheel of the folding chair.

[0008] The pan-tilt platform comprises a color mark sensor, an ultrasonic obstacle avoidance sensor, a first signal output end, and a first signal input end, and the color mark sensor, the ultrasonic obstacle avoidance sensor, the first signal output end, and the first signal input end are all located on the pan-tilt platform panel;

[0009] The hydraulic lifting table comprises a second signal output terminal, a second signal input terminal, a human infrared sensor, a thin-walled pressure sensor, a storage box, and a hydraulic lifter. Grooves are evenly arranged on the desktop of the hydraulic lifting table, and a thin-walled pressure sensor is arranged in each groove. A layer of rubber pad is covered on the desktop. A second signal output terminal, a second signal input terminal, and a plurality of human infrared sensors are arranged on the front side of the bottom of the hydraulic lifting table. The tops of the two table legs on the left side of the hydraulic lifting table are hinged to the desktop. A hydraulic lifter is respectively arranged between the tops of the two table legs on the right side of the hydraulic lifting table and the desktop. A storage box is also fixedly arranged between the two table legs on the left side of the hydraulic lifting table.

[0010] The seat reader includes a face recognition camera, a third signal output terminal, a display, a campus card sensor, a third signal input terminal, and a power wire. The face recognition camera is located above the display, the campus card sensor is located at the card swiping area below the display, the third signal output terminal and the third signal input terminal are respectively located on both sides of the display, and the power wire is connected to the seat reader and the socket;

[0011] The ground under the hydraulic lift table is marked with a red area line, and the front of the hydraulic lift table is marked with a green area line. The red area line and the green area line are equal in size and have corresponding positions.

[0012] The batteries in the battery box are used as power sources for the backrest, hydraulic lifting rod, pan / tilt platform and power system of the intelligent folding chair.

[0013] The third signal output terminal can transmit a signal to the first signal input terminal, the third signal output terminal can transmit a signal to the second signal input terminal, and the second signal output terminal can transmit a signal to the third signal input terminal, and the transmission method is radio transmission.

[0014] The first signal output end can transmit a seat activation signal or a seat locking signal to the color mark sensor. When the color mark sensor receives the seat activation signal, it can only distinguish green; when the color mark sensor receives the seat locking signal, it can only distinguish red.

[0015] When the student leaves and takes a seat, the thin-walled pressure sensor on the hydraulic lift table will transmit the pressure signal sensed by the learning tools and books on the table to the second signal output end, and the second signal output end will transmit the pressure signal to the third signal input end. The human infrared sensor on the bottom of the hydraulic lift table will transmit the sensed temperature reduction signal to the second signal output end, and the second signal output end will transmit the temperature reduction signal to the third signal input end. The third signal input end will transmit the pressure signal and the temperature reduction signal of the learning tools and books to the seat reader control system respectively. The seat reader control system will only send a leaving signal and a seat locking signal to the third signal output end when it receives the pressure signal of the learning tools and books sensed by the thin-walled pressure sensor and the temperature reduction signal sensed by the human infrared sensor at the same time for a certain period of time. The third signal output end will transmit the leaving signal to the second signal input end via radio, and the seat reader control system will control the display to display that the seat at this position is an empty seat. At the same time, the third signal output end will transmit the seat locking signal to the first signal input end via radio transmission.

[0016] When a student leaves temporarily, the seat reader control system cannot receive the temperature significantly reduced signal sensed by the human infrared sensor for a certain period of time, and the seat reader control system only receives the pressure signal of learning tools and books sensed by the thin-wall pressure sensor for a certain period of time. At this time, the seat reader control system will not send a departure signal and seat locking signal to the third signal output terminal, and the control system on the seat reader will control the display to show that the seat at that position is in use.

[0017] When the student takes off the learning tools and books on the desk and leaves, the pressure sensed by the thin-walled pressure sensor on the hydraulic lift table returns to the initial value, and the human infrared sensor on the bottom of the hydraulic lift table senses a significant decrease in temperature. When the student leaves the library, he / she will swipe the card on the seat reader, and the campus card sensor transmits the campus card sensing signal to the third signal input terminal, and the third signal input terminal transmits the departure signal to the seat reader control system. The seat reader control system controls the display to display that the seat corresponding to the campus card used is an empty seat. At this time, the seat reader control system transmits the seat locking signal to the third signal output terminal, and the third signal output terminal transmits the seat locking signal to the first signal input terminal through radio transmission. When the student leaves the library after use and forgets to swipe the card, even if a certain time is reached, the seat reader control system only receives the temperature significantly reduced signal sensed by the human infrared sensor for a certain time, and the seat reader control system does not receive the learning tool and book pressure signal sensed by the thin-walled pressure sensor for a certain time. At this time, the seat reader control system still transmits the seat locking signal to the third signal output terminal, and the third signal output terminal transmits the seat locking signal to the first signal input terminal through radio transmission.

[0018] If the student does not leave, regardless of whether the seat reader control system receives the pressure signal of the learning tools and books sensed by the thin-wall pressure sensor or the initial value of the sensed pressure, the seat reader control system will not receive the temperature significantly reduced signal sensed by the human infrared sensor. The seat reader control system will always control the display to show that the seat at this position is in use, and the seat reader control system will not send a departure signal or a seat lock signal to the third signal output terminal.

[0019] The beneficial effects of the present invention are:

[0020] Compared with the prior art, the present invention arranges a human infrared sensor and a thin-walled pressure sensor on the hydraulic lift table, which are respectively used to sense significant changes in temperature and significant changes in desktop pressure, and transmits the signals to the seat reader control system respectively. The seat reader control system sends a departure signal and a seat locking signal to the third signal output terminal only when the pressure signal of the learning tools and books sensed by the thin-walled pressure sensor and the temperature significant reduction signal sensed by the human infrared sensor are received at the same time for a certain time (occupied seat). The third signal output terminal transmits the departure signal to the second signal input terminal through radio, and the second signal input terminal controls the hydraulic lifter to rise, and the learning tools and books on the table slide into the storage box on the left side of the table; the seat reader control system controls the display to display that the seat at this position is an empty seat; at the same time, the third signal output terminal transmits the seat locking signal to the first signal input terminal through radio transmission, and the first signal input terminal further controls the intelligent folding chair to enter a locked state through the pan-tilt control system, which can accurately lock the use of the seat, eliminate the phenomenon of seat occupation, avoid contradictions and even conflicts between students and management personnel, improve the utilization rate of the library, and realize fair sharing of public resources.

[0021] In addition, a color mark sensor and an ultrasonic obstacle avoidance sensor are arranged on the cloud platform of the intelligent folding chair. The color mark sensor distinguishes the green area line and the red area line to control the moving direction of the seat. The ultrasonic obstacle avoidance sensor controls the moving speed and stop of the seat, thereby controlling the seat to freely enter and exit under the hydraulic lifting table and accurately shift. A face recognition camera, a display, and a campus card sensor are arranged on the seat reader. The display shows the seat usage, which is convenient for students to quickly find vacant seats. The face recognition camera and the campus card sensor check the information through the seat reader control system to confirm whether the campus card information and the face detection information are the same, so as to prevent borrowing campus cards to enter the library for study and disrupt the normal order of the library. The present invention has the characteristics of low cost and high sensitivity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Any related technical contents not described below may adopt or draw on existing technologies.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0034] like Figure 1-7As shown, the library intelligent anti-occupancy and cleaning device includes an intelligent folding chair 1, a hydraulic lift table 11, and a seat reader 19. The intelligent folding chair 1 and the hydraulic lift table 11 are placed in the library reading room one by one, and the seat reader 19 is fixed on the wall of the library entrance;

[0035] The intelligent folding chair 1 comprises a backrest 2, a battery box 3, a hydraulic lifting rod 4, a seat wheel 5, a pan platform 6, and a power system. The backrest 2 can be folded automatically. A battery box 3 is arranged below the seat surface of the folding chair, and batteries are placed in the battery box 3. A hydraulic lifting rod 4 is arranged below the battery box 3. Below the hydraulic lifting rod 4 is a folding chair base. An upright pan platform 6 is arranged on the folding chair base. Five chair legs are arranged under the folding chair base. A seat wheel 5 is arranged at the lower end of each chair leg, wherein the front seat wheel 5 is connected to the motor drive shaft of the folding chair power system to serve as a driving wheel of the folding chair.

[0036] The pan-tilt platform 6 includes a color mark sensor 14, an ultrasonic obstacle avoidance sensor 15, a first signal output terminal 16, and a first signal input terminal 17. The color mark sensor 14, the ultrasonic obstacle avoidance sensor 15, the first signal output terminal 16, and the first signal input terminal 17 are all located on the pan-tilt platform 6 panel;

[0037] The hydraulic lifting table 11 includes a second signal output terminal 7, a second signal input terminal 8, a human infrared sensor 9, a thin-walled pressure sensor 10, a storage box 12, and a hydraulic lifter 18. Grooves are evenly arranged on the desktop of the hydraulic lifting table 11, and a thin-walled pressure sensor 10 is arranged in each groove. A layer of rubber pad is covered on the desktop. The second signal output terminal 7, the second signal input terminal 8 and a plurality of human infrared sensors 9 are arranged on the front side of the bottom of the hydraulic lifting table 11. The tops of the two left legs of the hydraulic lifting table 11 are hinged to the desktop. A hydraulic lifter 18 is respectively arranged between the tops of the two right legs of the hydraulic lifting table 11 and the desktop. A storage box 12 is also fixedly arranged between the two left legs of the hydraulic lifting table 11.

[0038] The seat reader 19 includes a face recognition camera 20, a third signal output terminal 21, a display 22, a campus card sensor 23, a third signal input terminal 24, and a power wire 25. The face recognition camera 20 is located above the display 22, the campus card sensor 23 is located at the card swiping area below the display 22, the third signal output terminal 21 and the third signal input terminal 24 are respectively located on both sides of the display 22, and the power wire 25 connects the seat reader 19 and the socket;

[0039] The ground under the hydraulic lift table 11 is marked with a red area line, and the front of the hydraulic lift table 11 is marked with a green area line. The red area line and the green area line are of equal size and have corresponding positions.

[0040] The operation process of the present invention is as follows:

[0041] like Figure 2 As shown, the locked smart folding chair 1 is placed under the hydraulic lift table 11. At this time, the backrest 2 is folded, the hydraulic lift rod 4 is dropped, and the initial value of the pressure sensed by the thin-walled pressure sensor 10 on the hydraulic lift table 11 is set to the pressure of a layer of rubber pad on its cover.

[0042] The seat reader 19 is fixed on the wall at the entrance of the library. The display 22 on the seat reader 19 displays the current seat usage in the library. After entering the library, students swipe their campus cards at the card swiping area. At the same time, the face recognition camera 20 on the seat reader 19 takes a face photo of the student. The campus card sensor 23 transmits the campus card sensing signal to the third signal input terminal 24. The face recognition camera 20 transmits the face photo information to the third signal input terminal 24. The third signal input terminal 24 transmits the two signals to the seat reader control system for information verification to confirm the school card. Whether the campus card information and the face detection information are the same, prevent students who do not have the library use authority from borrowing campus cards from students who have the library use authority to enter the library to study, disrupting the normal order of the library and the rules for using library equipment. Students with authority can select an empty seat on the display 22, and students without authority will not have the opportunity to use the library's desk and chair resources. When the seat reader control system passes the student identity authentication, the seat reader control system transmits the seat activation signal to the third signal output terminal 21, and the third signal output terminal 21 transmits the seat activation signal to the pan / tilt 6 on the smart folding chair 1 through radio transmission. The first signal input terminal 17 transmits the seat activation signal to the pan-tilt control system, and the pan-tilt control system transmits the seat activation signal to the first signal output terminal 16. The first signal output terminal 16 transmits the seat activation signal to the color mark sensor 14. The color mark sensor 14 has the functions of distinguishing the color difference of the object and automatically correcting the deviation, so as to realize automatic positioning. At this time, the color mark sensor 14 can only distinguish the green color. The pan-tilt control system controls the power system of the intelligent folding chair 1 to drive the driving wheel of the folding chair to operate, and then controls the intelligent folding chair 1 to move to the green area line in front of the hydraulic lifting table 11. At the same time, the first A signal output terminal 16 transmits the seat activation signal to the ultrasonic obstacle avoidance sensor 15, which has the functions of high-precision distance measurement and accurate measurement of light intensity, assists the color mark sensor 14 in accurate positioning, and transmits distance data to the pan-tilt control system in real time so that the control system can timely control the movement rate of the smart folding chair 1, so that the smart folding chair 1 stops moving at a suitable position. After the smart folding chair 1 moves into the green area in front of the hydraulic lift table 11 and stops, the pan-tilt control system controls the backrest 2 to automatically unfold and controls the hydraulic lift rod 4 to rise. Students sit here, and students place learning tools and books on the desktop of the hydraulic lift table 11 and start learning.

[0043] Students leave in the following circumstances:

[0044] 1. Seat Occupancy

[0045] When a student leaves the library but occupies a seat during study (the student leaves for more than a certain period of time and does not take the books with him / her), the thin-walled pressure sensor 10 on the hydraulic lift table 11 will continue to sense the pressure of the study tools and books on the table, and the thin-walled pressure sensor 10 will transmit the pressure signal to the second signal output terminal 7, and the second signal output terminal 7 will transmit the pressure signal to the third signal input terminal 24. Once the student leaves, the human infrared sensor 9 on the bottom of the hydraulic lift table 11 will sense a significant drop in temperature, and transmit a significant drop in temperature signal to the second signal output terminal 7, and the second signal output terminal 7 will transmit the significant drop in temperature signal to the third signal input terminal 24, and the third signal input terminal 24 will respectively transmit the study tools and books to the second signal output terminal 7. The pressure signals of the tools and books and the temperature significantly reduced signals are transmitted to the seat reader control system. The seat reader control system is set to send a departure signal and a seat locking signal to the third signal output terminal 21 only when the pressure signals of the learning tools and books sensed by the thin-walled pressure sensor 10 and the temperature significantly reduced signals sensed by the human infrared sensor 9 reach a certain time (for example, 60 minutes) at the same time. The third signal output terminal 21 transmits the departure signal to the second signal input terminal 8 via radio, and the second signal input terminal 8 transmits the lifting signal to the hydraulic lift 18, controls the hydraulic lift 18 to lift, drives the right side of the hydraulic lift table 11 to lift, and the learning tools and books on the table slide to the left side of the table. The storage box 12 is in the storage box 12, the hydraulic lifter 18 rises and pauses for a while and then falls back, the hydraulic lift table 11 returns to a horizontal state, the seat reader control system controls the display 22 to display that the seat at this position is an empty seat, and at the same time the third signal output terminal 21 transmits the seat locking signal to the first signal input terminal 17 by radio transmission, the first signal input terminal 17 transmits the seat locking signal to the pan-tilt control system, the pan-tilt control system controls the backrest 2 to automatically fold and controls the hydraulic lift rod 4 to fall, the pan-tilt control system transmits the seat locking signal to the first signal output terminal 16, the first signal output terminal 16 transmits the seat locking signal to the color mark sensor 14, at this time, the color mark sensor 14 can only distinguish red, the pan The platform control system controls the power system of the intelligent folding chair 1, drives the driving wheels of the folding chair to operate, and then controls the intelligent folding chair 1 to move to the red area line under the hydraulic lift table 11. At the same time, the first signal output terminal 16 transmits the seat locking signal to the ultrasonic obstacle avoidance sensor 15, and its auxiliary color mark sensor 14 accurately locates and transmits distance data to the pan-tilt control system in real time so that the control system can timely control the movement rate of the intelligent folding chair 1 and stop at the appropriate position. The intelligent folding chair 1 moves into the red area under the hydraulic lift table 11 and stops. In this way, the intelligent folding chair 1 and the hydraulic lift table 11 there will be ready for the next student to come to study, waiting for the next student to swipe the card on the seat reader 19 to select activation.

[0046] 2. Temporary departure

[0047] The difference between this situation and the seat occupation situation is that when students go to the cafeteria to eat or leave for something temporarily, the students leave the library and return to their seats to study within a certain time (for example, 60 minutes). Since the seat reader control system receives the temperature reduction signal sensed by the human infrared sensor 9 for a certain time (for example, 60 minutes), the seat reader control system only receives the learning tool and book pressure signal sensed by the thin-walled pressure sensor 10 for a certain time (for example, 60 minutes). At this time, the seat reader control system will not send a departure signal and a seat locking signal to the third signal output terminal 21, the hydraulic lifter 18 and the intelligent folding chair 1 will not move, and the seat reader control system will control the display 22 to display that the seat at this position is in use.

[0048] 3. Leave after use

[0049] The difference between this situation and the seat occupation situation is that before leaving the library after use, the study tools and books on the desktop will be taken down. At this time, the sensing pressure of the thin-walled pressure sensor 10 on the hydraulic lift table 11 is restored to the initial value, and once the student leaves, the human infrared sensor 9 on the bottom of the hydraulic lift table 11 can sense that the temperature has dropped significantly. When the student leaves the library, he will swipe the card on the seat reader 19, and the campus card sensor 23 transmits the campus card sensing signal to the third signal input terminal 24, and the third signal input terminal 24 transmits the leaving signal to the seat reader control system. The seat reader control system controls the display 22 to display that the seat corresponding to the campus card is an empty seat. At this time, the seat reader control system transmits the seat locking signal to the third signal output terminal 21, and the third signal output terminal 21 transmits the seat locking signal to the first signal input terminal 17 via radio transmission. The first signal input terminal 17 transmits the seat locking signal to the pan-tilt control system, and the pan-tilt control system controls the movement of the backrest 2, the hydraulic lift rod 4, the color mark sensor 14, and the smart folding chair 1. The same as the seat occupation situation, which will not be repeated here. Moreover, even if the student forgets to swipe the card when leaving the library after use, because the learning tools and books on the desk have been removed, the thin-walled pressure sensor 10 on the hydraulic lift table 11 senses the pressure and returns to the initial value. Even if a certain time (such as 60 minutes) is reached, the seat reader control system only receives the temperature significantly reduced signal sensed by the human infrared sensor 9 for a certain time (such as 60 minutes), and the seat reader control system does not receive the learning tools and books pressure signal sensed by the thin-walled pressure sensor 10 for a certain time (such as 60 minutes). At this time, the seat reader control system will still transmit the seat locking signal to the pan-tilt control system through the third signal output terminal 21 and the first signal input terminal 17 in sequence, and control the movement of the backrest 2, the hydraulic lift rod 4, the color mark sensor 14, and the intelligent folding chair 1. The seat occupancy situation will not be repeated here. In this way, the intelligent folding chair 1 and the hydraulic lift table 11 here will be ready for the next student who comes to study, waiting for the next student to swipe the card on the seat reader 19 to select activation.

[0050] The student does not leave if:

[0051] No matter whether there are books or study tools on the table or not, that is, whether the seat reader control system receives the pressure signal of the study tools and books sensed by the thin-walled pressure sensor 10 or the sensed pressure is the initial value, and no matter how long a person sits there, the human infrared sensor 9 on the bottom of the hydraulic lift table 11 will not sense a significant drop in temperature, and the seat reader control system will not receive the significant drop in temperature signal sensed by the human infrared sensor 9. The seat reader control system will always control the display 22 to display that the seat at this position is in use, and the seat reader control system will not send a leave signal and a seat lock signal to the third signal output terminal 21, and the hydraulic lift 18 and the intelligent folding chair 1 will not move.

[0052] The batteries in the battery box 3 are used as power sources for the backrest 2 , the hydraulic lifting rod 4 , the pan / tilt platform 6 , and the power system of the intelligent folding chair 1 .

[0053] The surface of the seat wheels 5 is rough, which enhances the gripping ability of the seat, improves the stability of the seat during movement, reduces noise during movement, and creates a quiet library environment.

[0054] When the seat needs to be activated, the hydraulic lifting rod 4 rises, driving the seat surface to rise to a suitable height, and the backrest 2 automatically unfolds for students to use; when the seat needs to be locked, the backrest 2 automatically folds, and the hydraulic lifting rod 4 falls, driving the seat surface to fall to a suitable height, thereby lowering the center of gravity of the entire seat and improving the stability of the seat during movement.

[0055] The third signal output terminal 21 can transmit signals to the first signal input terminal 17 , the third signal output terminal 21 can transmit signals to the second signal input terminal 8 , and the second signal output terminal 7 can transmit signals to the third signal input terminal 24 , and the transmission methods are all radio transmission.

[0056] The first signal output terminal 16 can transmit a seat activation signal or a seat locking signal to the color mark sensor 14. When the color mark sensor 14 receives the seat activation signal, it can only distinguish green; when the color mark sensor 14 receives the seat locking signal, it can only distinguish red.

[0057] In addition, regarding seat occupation, the seat reader 19 will record the corresponding campus card. If a student has occupied a seat three times in total, the seat reader will automatically determine that the seat occupation is malicious, and the student will not be able to use the library's desk and chair resources through the campus card within seven days.
