Abstract
The invention discloses an unoccupied seat displaying device which comprises a detecting and sending part and a receiving and displaying part. The detecting and sending part is composed of a plurality of sets of detecting units, and each set of detecting unit is composed of an infrared emitting and receiving geminate transistor, a single chip microcomputer slave and a MAX487. The receiving and displaying part is composed of a single chip microcomputer mainframe, a displayer and a MAX487 corresponding to the single chip microcomputer mainframe. Every infrared emitting and receiving geminate transistor is installed in the middle of a seat back on the inner side of every seat and is directed at the seat direction, when a person takes one seat, the infrared receiving transistor receives an infrared signal reflected back by the human body and feeds back the signal to the single chip microcomputer slave of the set, the single chip microcomputer slave transmits the self serial number and the signal to the single chip microcomputer mainframe through an RS-485 bus, and after the serial number and the signal are processed by the single chip microcomputer mainframe, the result is transmitted to the displayer to display seat use conditions in real time.
Description
Technical field
The present invention relates to the automatic detection device technical field, is a kind of vacant scats display device specifically.
Background technology
College library, university library, academic library is that university students search data, borrows the place of books, and the study place that the self-study classroom of setting up in library is also university students to be favored.Look for and review one's lessons seat whenever the student enters library, all can shuttle back and forth at each floor for finding oneself " one seat " hurrying back and forth blindly, not only delayed time of learning, and the brouhaha produced has destroyed library's quiet atmosphere originally.At present, still do not have to recognize easily each self-study classroom of library the seat service condition, find smoothly the technical scheme at idle seat to solve this problem.
Summary of the invention
The objective of the invention is for above-mentioned deficiency of the prior art, in order to solve the problem existed in actual life, provide a kind of vacant scats display device of flexible for installation, real-time demonstration.
The objective of the invention is to be achieved through the following technical solutions:
A kind of vacant scats display device, comprise detecting transmitting portion and receiving and show part, described detection transmitting portion is comprised of many groups detecting unit, every group of detecting unit received pipe by infrared emission, (MAX487 is a kind of difference balanced type transponder chip that MAXIM company produces for single-chip microcomputer slave and MAX487 composition, it is the miniwatt transceiver for TTL agreement and 485 protocol conversions, it contains a driver and a receiver), described reception shows that part is by the single-chip microcomputer main frame, display and the MAX487 corresponding with the single-chip microcomputer main frame form, the effect of MAX487 in device is to form the transmission line of RS-485 bus between single-chip microcomputer main frame and a plurality of single-chip microcomputer slave.Every group of detecting unit and single-chip microcomputer main frame are by detecting unit and show that the RS-485 universal serial bus that the MAX487 in receiving unit forms between single-chip microcomputer main frame and single-chip microcomputer slave transmits data, adopt the RS-485 bus structure to realize the communication between main frame and many slaves, and more than the distance of communication can reach 1km, use enhancement mode RS-485 protocol chip, can reach the detection at thousands of seats, described infrared emission receives pipe is arranged on to the inboard chair back medium position in seat, aim at seat directions, when seat has the people to use, infrared receiving tube receives the infrared signal that human body is reflected back, and signal is sent out to this group single-chip microcomputer slave of feeding, the single-chip microcomputer slave sends the numbering of self and signal to the single-chip microcomputer main frame by the RS-485 bus, after the single-chip microcomputer host process, result is passed to described display, show in real time the seat service condition.The single-chip microcomputer main frame is for receiving the signal that slave sends over by the RS-485 bus, and, according to the RST content that display shows that upgrades in time, the service condition at each seat known on display panel and shown with the form of array.
Described single-chip microcomputer main frame and single-chip microcomputer slave can adopt low-power consumption, high performance 51 series monolithics.
Display can adopt frivolous liquid crystal display, is convenient to hang.
Concrete use-pattern is, single-chip microcomputer main frame, liquid crystal display and the MAX487 corresponding with the single-chip microcomputer main frame form an integral body, as the reception of whole device, shows part, can be arranged on obvious in the gate, library and be convenient to observation of students to metope on.LCDs shows the seat service condition of self-study classroom in real time, is convenient to the student and finds very soon the seat of reviewing one's lessons.1 single-chip microcomputer slave and corresponding MAX487 and infrared emission reception are done as a whole to pipe, the detection module that formation is used a seat, can be installed on the seat chair back, wherein infrared emission receives pipe is arranged on to position, chair back middle and upper part, and aim at the position at seat, when taking lower time, in order to detect in time.
Vacant scats display device of the present invention can also be widely used in the places such as station, train, cinema, meeting-place.
The present invention has following outstanding beneficial effect: technical scheme of the present invention can accurately detect fast vacant seat and take situation, by display, shows in real time Seats Occupied Information, real-time and clear; The component price needed is cheap, stable performance, and application places is extensive.
The accompanying drawing explanation
Fig. 1 is the principle schematic of vacant scats display device of the present invention;
Fig. 2 is display screen displaying contents schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Referring to Fig. 1, whole device is comprised of the two large divisions: detect transmitting portion 2 and receive demonstration part 1.Wherein receive to show that part 1 is comprised of single-chip microcomputer main frame 4, liquid crystal display 3 and the MAX487 corresponding with single-chip microcomputer main frame 4, can be arranged on obvious in the gate, library and be convenient to observation of students to metope on.By the seat service condition of self-study classroom, the form with array shows LCDs 3 in real time, as shown in Figure 2, take corresponding seat numbering if any the people and indicate by solid box, show by the dotted line collimation mark as nobody takies, be convenient to the student and find very soon the seat of reviewing one's lessons.Detect transmitting portion 2 by n infrared emission reception to managing 7, a n single-chip microcomputer slave 8 and n MAX487 form.Wherein 1 single-chip microcomputer slave 8 and corresponding MAX487 and infrared emission receive to manage 7 do as a whole, the detecting unit 6 that formation is used a seat, can be installed on the seat chair back, wherein infrared emission receives and is arranged on position, chair back middle and upper part to managing 7, and aim at the position at seat, when taking lower time, in order to detect in time, and the signal detected is sent to single-chip microcomputer main frame 4 by the RS-485 bus in time, 4, single-chip microcomputer main frame upgrades liquid crystal display by liquid crystal display 3 in time.
Be more than preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
