Abstract
The invention relates to a query system for empty seats of self-study classrooms, and belongs to the field of applications of the Internet of Things. The query system aims to solve the problem that students find seats difficultly for self-study, and comprises mobile RFID (radio frequency identification) tags, readers, sink nodes, a remote data processing center and a query terminal which are connected in sequence in a wired or wireless mode. The system effectively solves the problem that students find seats difficultly for self-study and forwards via relay nodes, thereby being low in total cost, stable and reliable in data transmission, simple in structure and small in error.
Description
Technical field
The present invention relates to a kind of inquiry system, concrete relate to a kind of vacant place, classroom inquiry system of reviewing one's lessons, belong to the technology of Internet of things application.
Background technology
At present, along with the universalness of higher education, the continuous increased enrollment of institution of higher learning causes part college teaching resource anxiety to a certain extent, particularly the amount of seats in classroom can not satisfy the demand that the student reviews one's lessons far away, has caused the university student looks for the seat difficulty when reviewing one's lessons problem thus.Sometimes, in order to find a vacant place, the classroom was gone to seek between the student needed to pursue under the upstairs house, time and effort consuming not only, and What is more, and fight in order to fight for the seat when the reviewing one's lessons bad phenomenon of quarrel of student has also appearred in the school that has.
There is following shortcoming in existing technology: calculate under the situation of vacant place, a plurality of classroom simultaneously (1), and error is bigger, has the possibility of erroneous judgement; (2) the vacant place data in each classroom receive and send processing enter to far-end without relay straight, and the cost height of total system, cost are big; (3) lack intermediate link, data transmission is stable inadequately, and reliability is not high.
Summary of the invention
In order to address the above problem, the invention provides a kind of vacant place, classroom inquiry system of reviewing one's lessons, can understand the quantity information of room for individual study vacant place in real time, for reviewing one's lessons the searching vacant seat, the student provides reference frame, reduce unnecessary trouble.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of vacant place, classroom inquiry system of reviewing one's lessons, comprise mobile RFID (Radio Frequency Identification, REID) label, read write line, aggregation node, remote data processing center and inquiry terminal, described mobile RFID label, read write line, aggregation node, remote data processing center and inquiry terminal are linked in sequence successively by wired or wireless mode.
Further improve, described inquiry terminal is fixedly inquiry terminal and/or mobile phones enquiring terminal.
Further improve, described remote data processing center is respectively by wired connection aggregation node and fixing inquiry terminal.
Further improve, described remote data processing center is by GPRS(general packet radio service technology, General Packet Radio Service) mode connects the mobile phones enquiring terminal.
As the further improvement of such scheme of the present invention, described vacant place, the classroom inquiry system of reviewing one's lessons also comprises the label with reference to RFID, connects read write line with reference to the RFID label by radiofrequency signal.
Further improve, described read write line is positioned at the centre position in classroom, and the antenna of read write line is selected omnidirectional antenna for use.
As the further improvement of such scheme of the present invention, described read write line is positioned at four diagonal positions in classroom, and the antenna of read write line is selected 90 ° of directional antennas for use.
The invention has the beneficial effects as follows:
(1) system architecture is simple, and error is little, the accuracy height;
(2) the vacant place data in each classroom directly are not sent to the processing enter of far-end, but transmit through via node, make that the cost of total system is low, cost is little;
(3) increase middle relaying link, make data transmission more stable, reliable.
Description of drawings
Fig. 1 is structure of the present invention and principle of work block scheme.
Fig. 2 is that reading and writing device antenna adopts 90 directional antenna working method scene graph.
Fig. 3 is that reading and writing device antenna adopts omnidirectional antenna working method scene graph.
Embodiment
The present invention is further detailed explanation with actual use below in conjunction with accompanying drawing.
Embodiment one:
This reviews one's lessons vacant place, classroom inquiry system, comprise mobile RFID label, read write line, aggregation node, remote data processing center and inquiry terminal, described mobile RFID label, read write line, aggregation node, remote data processing center and inquiry terminal are linked in sequence successively by wired or wireless mode.
The RFID label is implanted student's campus card, is convenient to school to the management of room for individual study vacant place.And be convenient for carrying and be difficult for losing.
Described read write line is positioned at the centre position in classroom, the antenna of read write line is selected omnidirectional antenna for use, read each RFID label in this classroom, and four corners in the classroom arrange the label with reference to RFID, connect read write line with reference to the RFID label by radiofrequency signal, so just can avoid read write line to read the label of the next classroom.
Read write line reaches remote data processing center with the RFID label information of reading through aggregation node, the record classroom account for seat and vacant place information.) utilize aggregation node, the relaying link in the middle of increasing makes data transmission more stable, reliable.
Inquiry terminal comprises fixedly inquiry terminal and/or mobile phones enquiring terminal, the mobile phones enquiring terminal is visited remote data processing center by the GPRS mode, fixedly inquiry terminal places teaching building, the student is behind teaching building, by fixed terminal inquiry vacant seat, reduce the trouble of searching vacant seat in classroom between pursuing under the upstairs house.By the mobile phones enquiring terminal, the student then can inquire about vacant seat information whenever and wherever possible.
Embodiment two:
This reviews one's lessons vacant place, classroom inquiry system, comprise mobile RFID label, read write line, aggregation node, remote data processing center and inquiry terminal, described mobile RFID label, read write line, aggregation node, remote data processing center and inquiry terminal are linked in sequence successively by wired or wireless mode.
The RFID label is implanted student's campus card, is convenient to school to the management of room for individual study vacant place.And be convenient for carrying and be difficult for losing.
Described read write line is positioned at four corner location in classroom, also is that four read write lines need be installed in each classroom, and the antenna of read write line is selected 90 degree directional antennas for use, utilizes four read write lines to read each RFID label in this classroom.
Read write line reaches remote data processing center with the RFID label information of reading through aggregation node, the record classroom account for seat and vacant place information.Utilize aggregation node, the relaying link in the middle of increasing makes data transmission more stable, reliable.
