Description

A method and system for checking attendance based on short messages

technical field

The invention relates to short message technology of a mobile communication system, in particular to a method and system for attendance checking based on short messages.

Background technique

Currently, only a few companies use the traditional mechanical punch time attendance system. Because the traditional mechanical punching attendance system prints the attendance records on paper cards, the attendance records are not only easy to be used by the enterprise managers, but also prone to data errors, and the time cards need to be replaced regularly, resulting in a waste of funds.

At present, most companies adopt the attendance management system based on radio frequency card technology. Figure 1 shows the working principle of the attendance system of radio frequency card technology. The system consists of four parts: radio frequency card, card reader, attendance information receiver and control PC. The unique identification number that distinguishes the identity of each employee is stored in the radio frequency card. Reading or rewriting this number requires a certain password, and the password is generally kept by the system administrator, and the password is also stored in the card reader and the attendance information receiver. When employees go to and from get off work, keep the distance between the radio frequency card and the card reader within 10 cm; the card reader can read the number in the radio frequency card and verify it according to certain rules. If it is correct, the card reader will flash or beep according to the settings. A buzzer sounds to notify the completion of the card reading process. The card reader sends the read number to the attendance information receiver through RS485 bus or CAN bus. When the RS485 bus is used, the attendance information receiver communicates with the card reader according to the polling method; if the CAN bus is used, the communication process is similar to the computer local area network, with high efficiency and reliability. After the attendance information receiver 4 receives the information sent by the card reader, if the information is correct, it can give the card reader a confirmation message. Then send the data to the monitoring PC through the Universal Serial Bus (USB: Universal Serial Bus) or serial port. The attendance information receiver also has the function of reading and writing cards, which is convenient for issuing new cards and rewriting the serial number in the radio frequency card. The software on the PC can store the received data into the database, and provide a variety of statistics, query and display modes, and can also be used in conjunction with other management systems of the enterprise. Although compared with the traditional mechanical punching attendance system, the attendance system based on radio frequency cards improves the intelligence of the company's attendance management, and can accurately and quickly count attendance data; since it does not need to issue paper cards repeatedly, it reduces wasted money. However, there are still some deficiencies in the attendance system based on radio frequency cards: 1) When employees clock in and out of work, they must put the radio frequency card close to the card reader, so that the information number exchange occurs between the radio frequency card and the card reader, and the card reader confirms the information The method is monotonous, only flashing or buzzing to notify the completion of the card reading process. There are often more employees waiting in front of the card reader to clock in when the working hours are approaching, and it is easy to be late due to delays in clocking in. Moreover, due to protocol issues, the card reader sometimes cannot ensure that the data is transmitted to the attendance information receiver.

2) The code in the radio frequency card is generally locked and has photos and other information printed on the surface. Once the radio frequency card is lost or a new employee enters the company, a new card needs to be made again, but the production procedure is cumbersome and the cycle is long. And once a company employee leaves the entire card becomes invalid.

3) The structure of attendance system based on radio frequency card is troublesome. In addition to the data cable required for data exchange between the card reader, attendance information receiver and PC, the cable between the card reader and the attendance information receiver is also responsible for supplying power to the card reader. The complicated wiring not only affects the indoor appearance, but also is not conducive to counting attendance outdoors.

Fig. 2 is the time attendance system based on the short message of the present invention.

Detailed ways

The present invention will be described in detail with the implementation process of the embodiment in conjunction with the accompanying drawings.

Taking the attendance identification signal response unit written in JAVA language as an example, as shown in Figure 2, the composition of the attendance system of the present invention includes four parts, namely base station 2, mobile communication terminal 1, JAVA attendance identification signal response unit and monitoring computer 3. The mobile communication terminal must support JAVA technology, for example: JAVA mobile phone or JAVA personal digital assistant (PDA).

After the new employee enters the company, he downloads the JAVA attendance identification signal response unit from the company website through the JAVA mobile phone 1 . In order to ensure the accuracy of attendance information, employees can download the JAVA attendance identification signal response unit according to their own numbers and download passwords, but after the JAVA attendance identification signal response unit is downloaded once, the original download password becomes invalid. If employees need to re-download the JAVA attendance identification signal response unit, they must re-apply for a new download password. After downloading, the JAVA attendance recognition signal response unit is always stored in the employee's JAVA mobile phone 1 .

Base station 2 is an isolated low-power base station, which does not have the ability to connect to the network subsystem (NSS), and only the control channel and the data traffic channel are valid, and only relevant protocols need to be implemented. Therefore, it is free for employees to send and receive text messages when registering attendance.

When employees need to register their attendance on and off work, the attendance management unit integrated in the monitoring computer 3 will automatically turn on the base station 2 during the attendance time (7:30-8:30 in the morning or 4:30-5:30 in the afternoon). A super micro attendance area is formed, and the radius of the community is within 10-15 meters. When the JAVA mobile phone 1 carried by the employee enters the attendance area, it will receive the attendance identification signal-identification code BSIC transmitted by the base station 2. The JAVA attendance identification signal response unit judges whether the JAVA mobile phone 1 enters the attendance area according to the identification code BSIC. If it enters the attendance area, the JAVA attendance identification signal response unit sends an encrypted short message to the base station for attendance registration. The encrypted short message contains the employee number , name, and gender.

After the attendance registration is successful, the base station 2 sends a confirmation message to the JAVA mobile phone 1 to notify the employees that the entire attendance registration process is completed. Attendance base station 2 transmits the received attendance registration information to monitoring computer 3 via USB (or serial port). The high-level attendance management unit stored in the monitoring computer 3 can receive the attendance information and store it in the database. At the same time, the monitoring computer 3 provides multiple query and display modes for managers and employees to query attendance information in real time. If it is necessary to perform attendance statistics outdoors, a laptop computer can be used as the monitoring computer 3 in the system.

The beneficial effect of the present invention is that, after entering the attendance femto cell with the mobile communication terminal, the employee registers the attendance information with the base station by sending a short message. After the attendance information registration is successful, the base station sends a confirmation message to the employee's mobile communication terminal to notify the completion of the attendance registration process. Because the base station works in the ultra-small cell and does not access the network, the sending and receiving of short messages is free. It not only saves the cost of making radio frequency cards for the company, but also avoids complicated installation and wiring, which is suitable for outdoor attendance management.

The above examples are only used to illustrate the implementation process of the present invention, but are not used to limit the present invention.
