Wireless active WIFI (wireless fidelity) access identification terminal

Abstract

The invention discloses a wireless active WIFI (wireless fidelity) access identification terminal, and relates to wireless access identification terminal equipment. The wireless active WIFI access identification terminal comprises an integrated circuit board fixedly arranged in a shell of terminal equipment. A touch screen is embedded on a surface of the shell, a microprocessor is disposed in the circuit board, is respectively connected with a crystal oscillator and a power module and is connected with a WIFI module by a USART (universal synchronous asynchronous receiver transmitter) interface to set and control the WIFI module, and network connection and data transmission and receiving are realized. An FSMC (fuzzy sliding mode control) bus of the microprocessor is connected with a TFTLCD (thin film transistor liquid crystal display) screen, so that data transmission is realized, and the TFTLCD screen is refreshed. The wireless active WIFI access identification terminal is scientific and reasonable in design and low in cost, the WIFI module is in many-to-one wireless communication connection with a wireless local area network server, multi-user simultaneous access management is realized, and the access management efficiency is greatly improved.

Description

technical field [0001] The invention relates to a device for identifying personnel entering and exiting, in particular to a terminal device for wireless entering and exiting identification. Background technique [0002] At present, when people enter and exit controlled areas such as computer rooms or access channels such as enterprises, institutions, factories, etc., they are generally managed according to the classification of personnel. For internal personnel, use authorized attendance IC cards or access cards to control and control. For external personnel, most of them mainly use handwritten registration by the gatekeeper. , this method is not only difficult to save but also difficult to find because of the paper registration, it is obviously unable to meet the management requirements of enterprises and institutions with a large number of departments and many departments. However, the electrical transformation of the system during installation will inevitably increase the...

[0002] At present, when people enter and exit controlled areas such as computer rooms or access channels such as enterprises, institutions, factories, etc., they are generally managed according to the classification of personnel. For internal personnel, use authorized attendance IC cards or access cards to control and control. For external personnel, most of them mainly use handwritten registration by the gatekeeper. , this method is not only difficult to save but also difficult to find because of the paper registration, it is obviously unable to meet the management requirements of enterprises and institutions with a large number of departments and many departments. However, the electrical transformation of the system during installation will inevitably increase the management cost. At the same time, although the system plays a role in post-mortem verification to a certain extent, it is often difficult to identify its true identity from the monitoring screen, and the monitoring is The passive defense system does not fundamentally play the role of effective early warning and prevention in advance
