Problems solved by technology

The biggest disadvantage of this network card is that the user needs to turn off the power manually. Once the user forgets to turn off the power, the wireless network will continue to transmit signals, which consumes power and may cause induced lightning strikes during the rainy season.

Embodiment Construction

[0027] The following describes in detail an automatic power-on / off device of a wireless network access device with an RJ45 interface provided by the present invention with reference to the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, in the usual wireless network card with RJ45 interface, the wireless network card 1E is connected to the network port 1G of the computer 1A through the network cable 1H, and the external DC power supply is powered for the network card through 1C; the antenna 1F is connected to 1E through the radio frequency cable 1D; To extend the communication distance, usually place 1F outside the window.

[0029] figure 2 It shows a wireless network card with an improved RJ45 interface, which is relatively figure 1 As shown, a Power over Ethernet (POE) module 2B is added. The power line 2N and the network line 2A are combined by the POE module 2B and connected to 2E through 2H to avoid using the network line and power l...

Abstract

The invention discloses an automatic on-off device for wireless network access equipment with an RJ45 port. The device consists of a wireless control component which is positioned at the wireless network access equipment end and a transmitting component which is connected to a PC system through a USB port. When a PC system is started, the transmitting component sends continuous control signals; the wireless control component then starts the wireless network access equipment after receiving the signals; while if the wireless control component receives no control signals for a certain time, thewireless control component then shuts down the wireless network access equipment.

Description

technical field [0001] The invention relates to the technical field of computer information wireless access, in particular, the invention relates to an automatic switch device of a wireless network access device with an RJ45 interface. Background technique [0002] WiFi is a wireless local area network (WLAN) based on the IEEE802.11b standard, and generally consists of an access point device and a user access device. The access point device completes the access of the wired network. The most common forms of user wireless network access devices are wireless network cards, wireless bridges, etc., which are used to complete the communication between the user computer and the access point device. [0003] The original WiFi is often used in homes, offices and public hotspots to replace cables. The user's wireless network access device is often a built-in wireless network card in a laptop or a wireless network card installed later. The wireless network card installed in the rear ...
