Attendance base station, attendance method and attendance system

Abstract

The embodiment of the invention provides an attendance base station, an attendance method and an attendance system. The attendance base station comprises a short-distance communication protocol module, a WiFi module and a control module, and the transmission distance of the short-distance communication protocol module is smaller than that of the WiFi module; the short-distance communication protocol module is connected with one end of the control module and comprises a short-distance communication protocol chip and a short-distance communication protocol antenna; the WiFi module is connected with the other end of the control module. The WiFi module comprises a WiFi chip, a WiFi module built-in antenna and a WiFi module external antenna, wherein the WiFi module built-in antenna and the WiFimodule external antenna have the same working frequency band. And when the control module confirms that the working frequency bands of the short-distance communication protocol module and the WiFi module are the same, the WiFi chip is controlled to be switched to an external antenna of the WiFi module. According to the embodiment of the invention, coexistence of the WiFi module and the short-distance communication protocol module is realized, so that the attendance base station not only has a traditional wireless function, but also has attendance and positioning functions, the deployment scheme of an attendance system is simplified, and the attendance cost is saved.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to an attendance check base station, an attendance check method, and a system. Background technique [0002] At present, in many occasions, in order to facilitate the arrival of inspectors, attendance is required, such as company employee attendance, student roll call, etc. With the development of science and technology, attendance methods are becoming more and more diverse, such as: paper attendance, fingerprint attendance, face recognition attendance, magnetic card attendance, etc. However, the above attendance methods require employees to actively participate, and there are many problems, such as: queuing up for attendance during the peak attendance period, forgetting attendance, etc. [0003] Due to the wide coverage of Wireless Fidelity (Wireless Fidelity, WiFi) at present, the smart attendance method based on WiFi is introduced, and WiFi...

AI Technical Summary

Problems solved by technology

However, the WiFi-based attendance method has a large coverage area but low positioning accuracy in a small area

[0004] Considering that Bluetooth, ZigBee and other short-distance communication protocols have the same working frequency band as WiFi, and they will interfere with each other when working at the same time. Therefore, in order to solve the problem of poor positioning accuracy of the attendance method based on WiFi, the existing technology can only be used in each attendance network. Adding multiple short-distance communication base stations such as Bluetooth base stations and ZigBee base stations cannot make use of existing WiFi base stations, resulting in complex deployment of the attendance system and high costs
