Description

Automatic borrowing system and method

The present invention relates to a borrowing system and method, and more particularly to an automatic borrowing system and method.

At present, most of the library's borrowing and returning books use manual registration to record the borrower's personal data and book materials, so it will cost a lot of manpower, and sometimes when people are busy, borrowers still have to wait in line to register for borrowing books. Or returning books, the efficiency is quite low.

To this end, some people use radio frequency identification (RFID) to place RF tags on each book, and then use the sensor and computer database system to establish an automatic loan backing system. When the automatic borrowing and returning system is used, the borrower only needs to bring the book on the hand close to the sensor, and the electromagnetic signal emitted by the sensor can drive the radio frequency tag on the book to emit the stored information (such as the title, book number, The publisher) returns the sensor, and after the computer database system receives the relevant information of the book from the sensor, the book can be compared and the loan backing process can be completed.

However, when borrowers borrow books, they usually borrow several books at the same time. So, when several books are stacked together, each RF tag is shot back. The electromagnetic signals of the sensor may interfere with each other or due to the shielding effect, which may cause the sensor to not correctly read the radio frequency label on each book, resulting in a number of errors in the borrowing and returning operation. In other words, there is still a serious lack of use in this automatic return book system, which deserves to be improved.

Accordingly, it is an object of the present invention to provide an automatic borrowing system and method that avoids errors in borrowing and returning jobs.

Therefore, the automatic borrowing and returning system of the present invention can simultaneously repay at least two unregistered books, the automatic borrowing and returning system comprising: a weighing unit, at least two identification members, a sensing unit, and a processing unit .

The weighing unit is configured to measure the weight of the unregistered books and generate an actual weight value. The identification members are respectively disposed on the unregistered books, and each of the identification members has identification information corresponding to the unregistered books. The sensing unit senses and reads identification information corresponding to the identifiers of the unregistered books in a wireless communication manner. The processing unit signal is connected to the weighing unit and the sensing unit, and includes a virtual weight generating module capable of generating a virtual weight value according to the identification information corresponding to the unregistered books, and receiving and processing the virtual weight The value is compared to the actual weight value of the module, and a borrowed confirmation module. The operation comparison module can drive the loan confirmation module to perform an unregistered book loan confirmation operation when the difference between the actual weight value and the virtual weight value is less than a predetermined value.

An automatic borrowing method of the present invention can be implemented by a system. The system includes a weighing unit, at least two are set separately in two An identification member on the book, a sensing unit, and a signal processing unit connected to the weighing unit and the sensing unit. Each identification component has built-in identification information corresponding to the unregistered book. The processing unit includes a virtual weight generating module, an operating comparison module, and a borrowing confirmation module. The automatic borrowing method includes the following steps: (a) causing the weighing unit to measure the weight of the unregistered books and generating an actual weight value; (b) causing the sensing unit to wirelessly sense and read the identification corresponding to the unregistered books (c) the virtual weight generating module of the processing unit generates a virtual weight value according to the identification information corresponding to the unregistered books; and (d) the operating unit comparison module of the processing unit The virtual weight value and the actual weight value, and when the difference between the actual weight value and the virtual weight value is less than a predetermined value, the loan confirmation module is driven to perform an unregistered book loan confirmation operation.

The effect of the invention is that the weight of the unregistered books is measured by the weighing unit, and the identification information stored by the identification components is read by the sensing unit, and the operation comparison module of the processing unit is When the difference between the actual weight value and the virtual weight value is less than the predetermined value, the loan confirmation module is driven to perform an unregistered book loan confirmation operation.

In this embodiment, the sensing unit 4 is a reader, and the reader reads the identification tag as a conventional technique, which will not be described here.

The warning unit 5 of the embodiment is connected to the sensing unit 4 and can be driven by the sensing unit 4 to issue an alarm message. In this embodiment, the alert unit 5 is, for example, a speaker, and the alarm message is an alarm sound. However, when it is implemented, it is not limited to the horn. For example, the luminaire can be matched with the light to achieve the warning effect.

The processing unit 6 of the embodiment is connected to the weighing unit 2 and the sensing unit 4. The processing unit 6 includes a memory module 61, a virtual weight generating module 62, a computing comparison module 63, a borrowing confirmation module 64, and a compensation module 65. In the embodiment, the processing unit 6 is a personal computer, but when implemented, it can also be a notebook computer or a tablet computer, as long as it is a device that can perform calculation.

The memory module 61 stores three pieces of book information respectively corresponding to a plurality of unregistered books 11, and each book information has a starting weight value corresponding to the weight of the corresponding unregistered book 11, wherein The starting weight value is the weight measured by the library when purchasing the unregistered book 11. Of course, each book information may also have a book name, a publisher, a book number, a publication date, and the like corresponding to the unregistered book 11.

The virtual weight generating module 62 is based on the identification information transmitted by the sensing unit 4, and the starting weight value corresponding to the unregistered books 11 is selected from the memory module 61 and added. A virtual weight value.

The operation comparison module 63 can receive and process the virtual weight value. And the actual weight value, and when the difference between the actual weight value and the virtual weight value is less than a predetermined value, the loan confirmation module 64 is driven to perform the unregistered book 11 loan confirmation operation. In addition, the operation comparison module 63 can drive the compensation module 65 to generate a compensation signal that can drive the sensing unit 4 to enhance its wireless communication power when the difference between the actual weight value and the virtual weight value is greater than the predetermined value. .

The sensing unit 7 of the embodiment can generate an opening signal when the borrower approaches. The opening signal can drive the weighing unit 2, the sensing unit 4 and the processing unit 6 to start operation. In this embodiment, the sensing unit 7 is an infrared sensor.

The automatic borrowing and returning method of the present invention can be implemented by the above system. The implementation steps of the automatic borrowing and returning method are as follows: First, as shown in step 901, the sensing unit 7 is in a detecting state.

Next, as shown in step 902, when the borrower approaches the automatic loanback system, the sensing unit 7 determines whether the borrower is approaching. If so, the sensing unit 7 generates the activation signal, and the activation signal drives the weighing unit 2, and the sensing unit 4 and the processing unit 6 start to operate. Conversely, when the borrower leaves, he returns to step 901.

Then, as shown in step 903, the borrower simultaneously stacks the three unregistered books 11 that are borrowed on the weighing unit 2, so that the weighing unit 2 can measure the weight of the unregistered books 11 and generate The actual weight value.

Then, as shown in step 904, the sensing unit 4 is wireless. The manner of communication senses and reads the identification information corresponding to the identification 3 of the unregistered books 11.

Then, as shown in step 905, the virtual weight generating module 62 of the processing unit 6 selects the identification information of the unregistered books 11 according to the sensing unit 4, and selects the same from the memory module 61. The virtual weight value is generated by adding up the initial weight value corresponding to the unregistered book 11.

Next, as shown in step 906, the operation comparison module 302 of the processing unit 6 compares the virtual weight value with the actual weight value, and determines whether the difference between the actual weight value and the virtual weight value is less than a predetermined value.

Next, as shown in step 907, if the difference between the actual weight value and the virtual weight value is less than the predetermined value, the operation comparison module 63 drives the loan confirmation module 64 to perform an unregistered book 11 loan confirmation operation. In fact, since the book is used for a certain period of time, the predetermined value is set because of a slight error in the weight measured at the beginning due to factors such as moisture or missing pages.

Then, as shown in step 908, when the difference between the actual weight value and the virtual weight value is greater than the predetermined value, the operation comparison module 63 drives the compensation module 65 to generate a driveable sensing unit 4 to enhance the Compensation signal for wireless communication power.

Next, as shown in step 909, the sensing unit 4 determines whether the transmitted wireless communication power reaches a maximum value. If yes, proceed to the next step. Otherwise, return to step 904.

Then, as shown in step 910, when the sensing unit 4 sends out When the wireless communication power reaches the maximum value, the warning signal is generated to drive the warning unit 5 to send an alarm message.

It is worth mentioning that the identification information built in each identification member 3 may also have a starting weight value corresponding to the weight of the corresponding unregistered book 11. Thereby, the virtual weight generating module 62 can directly add the initial weight values read by the sensing unit 4 to generate the virtual weight value. Therefore, the virtual weight generating module 62 can achieve the same effect as the step 905 without selecting the corresponding starting weight value from the memory module 61.

Specifically, the sensing unit 4 can sense the identifier 3 on the unregistered books 11 borrowed by the borrower, and the weighing unit 2 can measure the total weight of the unregistered books 11 and The actual weight value is generated, and the processing unit 6 is crossed to compare the actual weight value with the virtual weight value. Thus, when the identifier 3 of one or two unregistered books 11 is not read by the sensing unit 4 due to interference, the compensation module 65 first drives the sensing unit 4 to enhance the wireless communication power. When the wireless communication power is increased to a certain extent and the blocked identification component 3 cannot be read, the warning unit 5 is driven to issue an alarm message to notify the library personnel to process.

In summary, the present invention utilizes the design of the weighing unit 2, the sensing unit 4, and the processing unit 6, so that the sensing unit 4 can read the identification member 3 on the unregistered books 11 at the same time. The library staff can be notified to deal with it, so it can avoid mistakes in the number of books borrowed or returned. In addition, the sensing unit 7 can drive the scale when the borrower approaches The weight unit 2, the sensing unit 4 and the processing unit 6 are turned on, and further the power saving effect can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
