Abstract

The invention discloses on-board wireless local area network equipment, which comprises an interface module, a main control module and a power supply module, wherein the interface module is used for connecting on-board diagnostics (OBD) of a vehicle; the main control module is connected with the interface module; and the power supply module is connected with the interface module and the main control module, and used for acquiring a power supply from the OBD and providing power for the on-board wireless local area network equipment. The main control module comprises a first Wi-Fi module and a second Wi-Fi module, wherein the first Wi-Fi module is used for establishing a wireless local area network; and the second Wi-Fi module is used for being connected to an external wireless local area network. The technical scheme provided by the invention can realize a Wi-Fi function by using vehicle resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a vehicle-mounted wireless local area network device. Background technique [0002] At present, the application of wireless technology is becoming more and more extensive and mature. For example, the application of wireless fidelity (Wi-Fi, Wireless-Fidelity) technology in handheld devices, buses, trains, subways, and especially in smart phones in recent years has become very popular. universal. [0003] However, existing Wi-Fi devices are mostly installed in public places, offices or houses, and are fixed and cannot be moved. When a user leaves a public place, office place or house, the user cannot access the Internet through the Wi-Fi device. Although some smart phones currently support the WIFI hotspot function, the Wi-Fi hotspot of the smart phone itself has great limitations. For example, when the mobile phone turns on the WIFI hotspot function, the power consumption ...

Problems solved by technology

[0003] However, existing Wi-Fi devices are mostly installed in public places, offices or houses, and are fixed and cannot be moved. When users leave public places, offices or houses, users cannot access the Internet through this Wi-Fi device.

Although some smart phones currently support the WIFI hotspot function, the Wi-Fi hotspot of the smart phone itself has great limitations. For example, when the mobile phone turns on the WIFI hotspot function, the power consumption of the mobile phone will be increased, thereby reducing the battery life of the mobile phone

The battery will be drained faster, which requires frequent charging of the phone, and adds a lot of cables and power accessories
