technical background

Due to the rapid development of computer technology, electronic devices with wireless communication capabilities such as mobile phones and laptop computers have become mainstream. Wireless communication technology enables people to communicate visually or audibly with others anytime, anywhere. This not only breaks the constraints imposed on people by time and space, but also increases the speed of information exchange between people and regions, and connects the world as a whole. .

In the field of personal computers, there are many wireless communication protocols used, and there are mainly two types of them in the market, one is the IEEE 802.11 communication protocol, and the other is the Bluetooth communication protocol (bluetooth).

IEEE 802.11 communication protocol is a relatively mature network technology at present. It uses a technology called Direct Sequence Spread Spectrum (Direct Sequence Spread Spectrum). Its data transmission is limited to a certain bandwidth, although it is difficult to be detected. However, when faced with interference sources that use high frequencies such as frequency hopping (Frequency Hopping, FH) or microwaves, they are very fragile and easy to be interfered by. As for the increasingly prosperous Bluetooth communication protocol, frequency hopping technology is used. Therefore, if a computer using the IEEE 802.11 communication protocol is not far away from another device using the Bluetooth communication protocol, the wireless communication capability of the computer will reduce its function due to interference, or even fail to communicate.

Since the bandwidths of IEEE 802.11 and Bluetooth technology are close and cannot coexist, it is known that computers with wireless communication capabilities only support one of the two. As a result, the laptop is still in a wireless environment with different standards and changes in different places. However, it may not be usable due to differences in communication specifications or interference with the environment.

Detailed ways

FIG. 1 is a schematic diagram of the use state of the switching switch of the wireless communication device of the present invention. The notebook computer 10 is built with IEEE 802.11 communication module and bluetooth technology communication module, and it is respectively installed in the hinge 18 that is used to rotate the screen loam cake, to make full use of the remaining space in the hinge 18.

The laptop computer 10 has a keyboard set 17 including several user-defined function keys 19 . The present invention uses the user-defined function key 13 as a switching switch to control both the IEEE 802.11 communication module and the Bluetooth technology communication module. The user only needs to press the switching switch 13 to complete the action of switching between different communication systems. Compared with the conventional technology, the user has to use the mouse to click on the image, which has the advantage of being fast and convenient. And because the switch of prior art only stops at opening and closing a single wireless communication device, and switch 13 of the present invention has the function of opening and closing two kinds of different wireless communication devices, so switch 13 of the present invention is compared with conventional Technology has obvious progress.

In addition, since the wireless communication device switching switch 13 of the present invention is used to switch between two different wireless communication devices, in order to let the user clearly know which of the two is on and which is off at the moment, the present invention is provided with a display on one side of the switching switch 13 device 15. The display device 15 can emit light of different colors according to different switch conditions, so as to remind the user of the current switch conditions of the wireless communication device.

FIG. 2 is a switching mode diagram of the switching switch 13 of the wireless communication device of the present invention. The display device 15 can usually be a color-changing LED or a liquid crystal display screen. First, in the initial state 21, both the Bluetooth device and the IEEE 802.11 device are turned off, and the display device 15 does not emit light at this time. When the user depresses the switching switch 13, it enters the first switching state 22, and now the Bluetooth device is turned on, the IEEE 802.11 device is turned off, and the display device 15 emits green light. When the user depresses the switching switch 13 again, it will enter the second switching state 23. At this time, the Bluetooth device is turned off, the IEEE 802.11 device is turned on, and the display device 15 changes to orange light. Finally, when the user depresses the switching switch 13 again, the initial state 21 is returned. At this time, the Bluetooth device and the IEEE 802.11 device all return to the off state, and the display device 15 does not emit light.

Therefore, the switching switch 13 of the present invention has a cyclic switching mode. By pressing the switching switch 13, the user can easily complete the purpose of switching between Bluetooth technology and IEEE 802.11 two different wireless communication devices in a cyclic manner. In addition, according to the display The different colors of light emitted by the device 15 allow the user to know that the current opener is Bluetooth technology or IEEE802.11, so as to eliminate the inconvenience caused by the user forgetting the previous setting.

FIG. 3 is an operation flowchart of an embodiment of the switching switch of the wireless communication device according to the present invention. Usually, installing a wireless communication device requires installing related drivers in the operating system, so the two drivers of the Bluetooth device and the IEEE 802.11 device of the present invention have been installed in the operating system. In this embodiment, a resident monitoring program installed in the system monitors whether the switching switch 13 is pressed, and calls the switching program to execute the switching action accordingly. The switching program will be used to turn on or off the IEEE 802.11 The driver program of the wireless communication device and the driver program for turning on or off the Bluetooth technology wireless communication device are integrated into one, and through the cooperation of the switching program and the switching switch 13, the user can easily complete the switching action. Certainly, when the driver program of one wireless communication device is started, the switching procedure will also shut down the driver program of another wireless communication device. The process is as follows. First, when the switch is pressed (step 31), a system management interrupt (SMI) signal is generated and sent to the basic input output system (BIOS). After the BIOS obtains the signal, it indicates that the switch is pressed, and then records the event in a block of the CMOS memory (step 33). Since the monitoring program is a resident program, it requests the content of this block from the BIOS at a fixed time interval (polling), so when the BIOS records the event that the switch is pressed, the monitoring program can then detect The switch is pressed (step 35). After the monitoring program detects that the switch is pressed, it calls the switching program (step 37), and the switching program executes the switching action in the order shown in FIG. 2 according to the switch states of the two current wireless communication systems (step 39).

FIG. 4 is an operation flowchart of another embodiment of the switching switch of the wireless communication device of the present invention. In this embodiment, the power control interface (Advanced Configuration & Power Interface, APCI) provided by the Windows operating system is used to simulate the signal transmitted by the switch 13 as a signal for inserting (or extracting) a hardware device. When the operating system receives When the simulated insertion (or extraction) signal is received, the action of turning on (or turning off) the IEEE 802.11 or Bluetooth technology communication module is executed, and the process is as follows: first, when the switch is pressed (step 41), a The SMI signal is sent to the APCI BIOS. After the ACPI BIOS receives this signal, it indicates that the switch is pressed, and then this event simulates a hardware insertion (or extraction) signal according to the specification of the APCI interface and sends it to the operating system (step 43). The operating system receives this analog signal (step 45), which means that the switch has been pressed, and then calls the switching program (step 47). The switching program is based on the switch status of the current two wireless communication systems, according to the sequence described in Figure 2 Execute switching action (step 49).
