Abstract
A student attendance management system comprises a plurality of terminals arranged in each classroom for reading data of campus RFID cards of students entering the classroom and storing the data in the memory of the terminal for later polling and a control computer for polling each terminal periodically, wherein the terminals transmit the RFID data to the control computer after receiving data request information, then the control computer transmits the data to a server through a serial port, and the student attendance management system also comprises the server for receiving data transmitted from the control computer and storing the data in a database in the server. The terminal comprises a CPU, an RFID module communicatively connected with the CPU, a CPLD module, a network card module and a USB module, wherein CPLD module is connected with an ASK transmitting module and an ASK receiving module. The student attendance management system can effectively manage the student attendance through wireless communication, network communication and manual collection, thereby effectively improving teaching and investigating the student information.

Embodiment
As shown in Figure 1, a kind of campus Work attendance management system comprises:
Many station terminals machine, every described terminating machine can adopt arm processor, is located at every classroom, to the student's that enters the classroom RFID campus card read data, and is kept in the internal memory of terminating machine, and waits for the inquiry of main control system;
Main control system, it is 3 kms that described main control system adopts transmitting range, by 433M, each station terminal machine of ASK radio broadcasting mode automatic regular polling, described terminating machine sends to main control system to the RFID data of reading after receiving request of data information, and described main control system sends the data to server by serial ports after receiving data;
Server, receive the data that described main control system sends after, it is deposited in the database in the described server, be used for further analyzing and processing.Described server also can be a PC.
As shown in Figure 2, described terminating machine comprises CPU, the RFID module, the CPLD module that are connected with described CPU communication, is connected with ASK sending module and ASK receiver module on the described CPLD module.
Wherein, also comprise the network interface card module that is connected with described CPU communication, described network interface card module and described server insert campus network, as shown in Figure 3.Realize the telecommunication of described terminating machine and described server by campus network, the student's that reads RFID campus card data are sent in the described server.
Wherein, also comprise the USB module that is connected with described CPU communication.Realize artificial the collection by this USB module.This mode is fit to not have campus network and the severe occasion of wireless communications environment.Occasions such as for example buildings is serious to the wireless signal shielding, and communication distance is long.Described terminating machine is kept at internal memory to the data that RFID reads in, and waits personnel's to be collected collection.The picker only need insert the USB flash disk of band authentication file, and data just import USB flash disk automatically.Then, USB flash disk is inserted described server, the management software that runs on the described server just can read in data
Wherein, the model of the CPU of described terminating machine is the processor of LPC2114, and described network interface card module is the CS8900 network card chip, and described USB module is the PDIUSBD12 chip.
Wherein, described RFID module is the RFID module of band Wei root interface.Described RFID module and CPU can adopt Wei root protocol communication, adopt complicated logic element (CPLD) transfer between described CPU and ASK receiver module, ASK send, and this CPLD can adopt graceful Chester coding decoder, and it is a transparent transmission for serial communication.Because the high-gain that receives can not receive a lot of clutters when having wireless signal, the serial communication program meeting can't operate as normal.And graceful Chester coding all has wireless transmit regardless of 0 and 1, can guarantee to have in work wireless transmit to exist, and therefore the main control system as receiving end can be correctly decoded communication code, has avoided introducing when a period of time just is data 0 interference.Simultaneously, because CPLD has added synchronous head, therefore guarantee can not receive data immediately in the communication.
