Accompanying drawing explanation
Fig. 1 is the structural representation of Librarians flow statistical system based on pressure transducer of the present utility model.
Fig. 2 is the application scenarios top view of Librarians flow statistical system based on pressure transducer of the present utility model.
Fig. 3 is that the pressure transducer of Librarians flow statistical system based on pressure transducer of the present utility model arranges position view.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As it is shown in figure 1, Librarians flow statistical system based on pressure transducer, including single-chip microcomputer, and the power supply of pressure sensor circuit, key circuit, display screen, buzzer, display lamp and the power supply being connected with single-chip microcomputer respectively；Pressure sensor circuit includes the first pressure transducer and the second pressure transducer, first pressure transducer and the second pressure transducer are connected with single-chip microcomputer by analog to digital conversion circuit respectively, first pressure transducer is positioned in entry position, library is entered for sensing personnel, second pressure transducer is placed in exit position, leave library, above-mentioned first pressure transducer and the second pressure transducer model be NS-TH6 for sensing personnel.Above-mentioned single-chip microcomputer model is STC89C52, is responsible for processing the data of pressure transducer collection, and coordinates the work of other modules；Power supply plays power supply transduction, powers for whole system；Display lamp is LED, is used for pointing out current system duty, and when system is in running order, display lamp is bright, and during system stalls, display lamp goes out；Display screen is LCDs LCD1602, is shown by real-time for the data of statistics, checks for librarian.Key circuit includes on & off switch, reset key and abort key, and on & off switch is as the switch of the whole device of control, and reset key is for controlling statistical data clearing before, and abort key is used for suspending counting；Buzzer is used for pointing out statistical result, carries out high frequency chimes of doom when exception, sends all-bottom sound prompting time normal.
During use, as Figure 2-3, pressure transducer 1 is installed to the porch of library, pressure transducer 2 is installed to the exit of library, particular location is below the ferrum pedal between gate inhibition's column, and after pressing on & off switch and reset key, system can be started working.When there being people to pass through gateway, step on the ferrum pedal between column, it is now placed in the pressure transducer below pedal and pressure signal will be detected, pressure transducer is sent to single-chip microcomputer after being quantified by analog to digital conversion circuit by pressure signal in real time, single-chip microcomputer by force value distinguish be single by or many people pass through, statistical number of person information, statistical result transmission shows to display screen.After pressing counting abort key, turnover library number is compared by single-chip microcomputer, determine whether that personnel are detained library by comparative result, if turnover library number is consistent, buzzer will send low-frequency sound and carry out " normally " prompting, otherwise buzzer sends high-frequency sound and carries out alarm, and information is shown on display screen.
Librarians flow statistical system based on pressure transducer of the present utility model, number based on pressure sensor monitoring turnover library, allow many people simultaneously by doorway column, accuracy of detection is high, turnover shop number can be carried out real-time statistics, when closing shop, turnover shop number is compared, discovery personnel send indicating alarm when being detained, the generation of the event that student is detained, convenient management after can effectively avoiding closing shop, reduce manager's working strength, and system is simple, it is convenient to implement, and has a good application prospect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
