WAPI wireless access point, wireless system and control method thereof

Abstract

The invention discloses a WAPI wireless access point, a wireless system and a control method thereof. The WAPI wireless access point comprises a communication unit, a power management control unit, a WAPI system, a main power supply, a WAPI system power tree and a controlled power supply switch, wherein the communication unit is used for acquiring external dormancy policy scheduling information and transmitting the external dormancy policy scheduling information to the power management control unit; the power management control unit is used for analyzing the dormancy policy scheduling information, sending a notification to the WAPI system when an analysis result contains a shutdown instruction, and controlling the controlled power supply switch to cut off power supply of the main power supply to a WAPI system power tree after a feedback instruction is received; and the WAPI system takes power from the WAPI system power tree for operation, is triggered by the notification instruction sent by the power management control unit to execute power-off data storage logic, and returns a feedback instruction. According to the invention, the system architecture is improved to introduce a dormancy mechanism, so that the working time of a WAPI wireless access point (AP) powered by an outdoor single battery is prolonged.

Description

technical field [0001] The invention relates to communication technology, in particular to a WAPI wireless access point, a wireless system and a control method thereof. Background technique [0002] Today's common IEEE 802.11 series standard technology adopts a binary security architecture. The wireless access point (AP) has no independent identity and uses the American encryption algorithm AES. There are many security holes in various existing devices, such as WPA2 and WPA3. KRACK, Dragonblood and other vulnerabilities. [0003] The equipment based on WAPI technology adopts a ternary peer-to-peer security structure, and no security loopholes have been found so far, which solves the security problems existing in IEEE 802.11 series standard technologies and achieves the following functions: [0004] 1) Bandwidth: a variety of bandwidth devices to meet the bandwidth requirements of different scenarios; [0005] 2) Coverage: Most of them are aimed at indoor wireless data tran...

Problems solved by technology

[0005] 2) Coverage: Most of them are aimed at indoor wireless data transmission, and the coverage is small;

[0010] In addition, the existing WAPI technology also continues the use scene characteristics of IEEE 802.11 series standard technical equipment, without energy-saving technologies such as sleep mechanisms, and it is difficult to meet the application of battery-powered and long-term unmanned inspection scenarios, such as the power industry Transmission tower data transmission, in the no-load scenario without data transmission, it is necessary to reduce the energy consumption of the WAPI wireless access point (AP) to seek a longer battery life

The reason is that the baseband chip of the WAPI wireless access point (AP) does not have a dormancy mechanism, which leads to defects in the baseband chip, and there is no energy-saving technology in the technical framework, which does not meet the needs of application scenarios with power consumption control.
