An attendance base station, attendance method and system

Abstract

Embodiments of the present invention provide an attendance check base station, an attendance check method, and a system. The attendance base station includes: a short-distance communication protocol module, a WiFi module and a control module, the transmission distance of the short-distance communication protocol module is less than the transmission distance of the WiFi module; the short-distance communication protocol module is connected with one end of the control module, and the short-distance communication protocol module It includes a short-distance communication protocol chip and a short-distance communication protocol antenna; the WiFi module is connected to the other end of the control module, and the WiFi module includes a WiFi chip, a built-in antenna of the WiFi module with the same working frequency band, and an external antenna of the WiFi module; When the working frequency band of the communication protocol module is the same as that of the WiFi module, control the WiFi chip to switch to the external antenna of the WiFi module. The embodiment of the present invention realizes the coexistence of the WiFi module and the short-distance communication protocol module, so that the attendance base station not only has the traditional wireless function, but also has the attendance and positioning functions, simplifies the deployment scheme of the attendance system, and saves the attendance cost.

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
