Description

Human body induction energy-saving RFID time attendance machine

technical field

This application relates to RFID (radio frequency identification) time attendance machine, especially the human body induction energy-saving RFID time attendance machine.

Background technique

The RFID attendance machine is used to read attendance information from the outside and record attendance. When in use, its internal devices are generally in working condition 24 hours a day. If you want to reduce the power consumption of the RFID time attendance machine during the time when attendance is not required, you need to manually turn off the RFID time attendance machine, and then manually turn on the RFID time attendance machine when attendance is required, which is troublesome to operate.

Contents of the invention

The purpose of this application is to provide an RFID time attendance machine that can reduce power consumption without manually switching the machine on and off.

Provide human body induction energy-saving RFID time attendance machine for this reason, comprise main control single-chip microcomputer, main control single-chip microcomputer connects memory and RFID radio frequency base station, described main control single-chip microcomputer is band timer, main control single-chip microcomputer is also connected with human body induction module.

Because the main control single-chip microcomputer is equipped with a timer, it can perform timing. If the RFID radio frequency base station does not receive the attendance signal within the specified time, the main control single-chip microcomputer will turn off the RFID radio frequency base station, reducing the work on the premise of avoiding manual switching. consumption. The main control microcontroller is connected with a human body sensing module, which uses the principle of infrared rays, and it can sense when someone enters the sensing range. At this time, the main control single chip computer turns on the RFID radio frequency base station to receive attendance signals.

Description of drawings

Fig. 1 is a schematic block diagram of the internal and external operation of the human body induction energy-saving RFID time attendance machine of the present invention.

Detailed ways

Below in conjunction with Fig. 1, describe the utility model in detail.

The human body induction energy-saving RFID attendance machine includes a main control single-chip microcomputer with a timer, and the main control single-chip microcomputer is connected with an RFID radio frequency base station, a human body induction module, a communication module, a memory, a display and a keyboard. If the RFID radio frequency base station does not receive the attendance signal within the specified time (for example, 5 minutes), the main control microcontroller will turn off the RFID radio frequency base station, memory, display and keyboard, reducing power consumption while avoiding manual switching. The human body sensing module itself is an existing technology. It uses the principle of infrared rays. It can sense when someone enters the sensing range. At this time, the main control single-chip microcomputer turns on the RFID radio frequency base station, memory, display and keyboard to receive attendance signals. The communication module is used to connect to the management terminal computer. When the management terminal computer needs to read and write data with the RFID attendance machine, it sends a data read and write command to the communication module, and the main control microcontroller opens the memory to read and write data accordingly. If the communication module does not receive the data read and write command within the specified time (for example, 5 minutes), the main control microcontroller will turn off the memory to reduce power consumption.

The above are only preferred embodiments of the present application, and equivalent technical solutions on this basis still fall within the protection scope of the application.
