Abstract
The utility model provides an instrument for checking work attendance, which is composed of a memory, a clock display, a reading circuit of identity codes, an LED display circuit, a communication interface circuit, a pressure reducing circuit, and a micro processor. The microprocessor is respectively connected with the circuits, and work attendance data are caused to be immediately classified, collected, and archived in a manage computer. Accordingly, the instrument for checking work attendance which can realize real-time checking and management to units and work attendance contents is convenient for the units to conduct scientific management to the work attendance of employees. Work efficiency is increased.
Description
The utility model relates to a kind of Time Attendance Device, particularly a kind of Instrument for checking work attendance.
Along with the quickening of live and work rhythm, people's concept of time strengthens day by day, relatively stable in order to ensure the working time, and work attendance every day has become an important means of numerous companies.But now, the Instrument for checking work attendance that generally uses in office, enterprises and institutions mostly is mechanical card at present, and the unit use, therefore is not easy to realize real-time appraisal management.
The purpose of this utility model provides and a kind ofly can overcome the problems referred to above, can carry out the novel Instrument for checking work attendance of real-time appraisal management to the work attendance content.
The purpose of this utility model is achieved in that it reads circuit, LED display circuit, communication interface circuit, reduction voltage circuit and microprocessor by storer, clock display, identity code and form, and microprocessor links to each other with foregoing circuit respectively.
The utility model and identity code device, bus controller and supervisory computer constitute Work attendance management system jointly.
When using the utility model, when the employee of unit is on and off duty, only need the identity code device (its code is corresponding one by one with the employee) of oneself is inserted in Instrument for checking work attendance, promptly finished work attendance on and off duty.Instrument for checking work attendance and supervisory computer are classified, gather, are filed the work attendance situation by supervisory computer by bus controller and network, can finish work attendance work.
Because the utility model directly links to each other with supervisory computer, therefore attendance data can obtain classifying, gathering, file in the very first time in supervisory computer, so can realize the Real-time and Dynamic supervision is carried out in attendance work, thereby company management provides the authentic data data.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a functional-block diagram of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
As shown in the figure, the utility model comprises that storer (X25045), clock display, identity code read circuit, LED display circuit, communication interface circuit (MAX485), reduction voltage circuit and microprocessor (AT89C2051) and form, and microprocessor links to each other with foregoing circuit respectively.Behind the confession 12V of system direct current, through reduction voltage circuit output 5V operating voltage, power supply indication red light is bright, insert one extracting behind the identity code key, P3 by microprocessor (AT89C2051), after reading, 7 pin deposit in the storer, the TXD end of microprocessor (AT89C2051) always sends to the attendance management machine with this code by communication interface circuit (MAX485), compare successively with registered key code in the supervisor, after if the identical correct information of Instrument for checking work attendance of passing to, Instrument for checking work attendance are received by the RXD termination, put the bright 3S of LEDR green light of LED display circuit, the expression work attendance is passed through, and by supervisor additional period information.If there is not this key code in the supervisor, Instrument for checking work attendance receives an error message, and the LED display circuit does not show any information, represents that this is invalid key.
