Control system with dual hosts

Abstract

A control system with double host comprises the first unit, the first host and the second unit. It is featured as forming the first host by host based on computer, electric-connecting the first host to the first unit and the second unit as the first unit being used to control the second unit.

Description

technical field [0001] The invention relates to a control system, in particular to a method and system with dual hosts. Background technique [0002] In today's world, wireless communication is becoming more and more popular. A typical wireless network system includes an access point (AP) for accessing the network, and a network interface card (NIC), also known as a PC wireless card. With the advancement of technology, the wireless card of the personal computer is integrated into a chip or a chipset, or is integrated into the motherboard. [0003] Figure 1 shows a traditional computer system with a wireless chip. The mainboard 10 includes a WLAN (wireless local area network) chip 103 used as a wireless local area network card for a personal computer. The WLAN chip 103 transmits and receives signals to the access point 12 by means of the antenna 11, and further processes data in the South Bridge chip 101 through the PCI (Peripheral Component Interconnect) bus 102, wherein ...

And when the computer is turned off or enters standby or sleep mode, any expansion card on the motherboard cannot work

[0005] So if the original host is turned off or enters sleep mode or similar mode, then any other host in the original circuit cannot control the client, for example: if an expansion card, access point has a host, And when it is about to become the host to control the WLAN client, if the original host, such as the south bridge chip, has entered sleep mode or a similar mode, then the expansion card or access point cannot control the WLAN client.

[0006] And this similar problem will also occur when other hosts are about to start controlling clients that the original host already controls

For example, when an MP3 player controls a built-in CD recorder through a computer system, or a digital camera controls a printer through a computer system, if the computer system is shut down or enters sleep or standby mode, then The MP3 player and digital camera in the above example no longer have the ability to control
