Description

A kind of wireless remote control system based on Wifi

Technical field

The utility model relates to remote control technical field, especially a kind of wireless remote control system based on Wifi.

Background technology

Nowadays a lot of needs is had long-rangely to carry out operational applications scene to computer, such as, to the operation of outdoor advertisement screen.At present, what realize remote computer operation mainly contains 2 classes: a kind of use 2.4G or 5.8G wireless transmit-receive technology realize, and are typically wireless mouse and keyboard; Another kind is remote control software, is typically remote desktop and the QQ remote assistance of Windows.

Above-mentioned two kinds of modes are obtained for a certain extent to be applied widely, but also has very large deficiency: 2.4G or 5.8G wireless transmit-receive technology, due to the restriction of equipment, is difficult to realize model relaying, just cannot receiving and transmitting signal when reaching certain distance.Remote control software utilizes Transmission Control Protocol, by local area network (LAN) or wide area network, achieves the Long-distance Control of computer, but this mode must use an other computer to carry out remote operation, and operate inconvenience.

Utility model content

Propose a kind of wireless remote control system based on Wifi, the connection of the computer peripheral of overlength distance can be realized, with the form of server, multiple stage be provided, multiple external equipment connects simultaneously and provide double-direction control for external equipment and computer.

The technical scheme that the utility model adopts is: a kind of wireless remote control system based on Wifi, comprises controlled terminal and main control end; Between described controlled terminal and main control end by TCP IP agreement carry out transfer of data; Described controlled terminal is PC computer; Described main control end comprises processor module, wifi module and usb interface module; Described usb interface module connects input equipment or output equipment; The packet that described processor module receives the instruction that sends of controlled terminal by wifi module or sends input equipment is to controlled terminal; Described controlled terminal is provided with the driver module corresponding with main control end usb interface module.

Further, main control end described in the utility model detects the interruptive command of input equipment, and this interruptive command and equipment I d are encapsulated as command message, use TCP IP protocol transmission to the listening port of controlled terminal; After described controlled terminal receives this command message, according to equipment I d, find corresponding virtual unit, the driver sending to virtual unit corresponding interruptive command.

Further say, controlled terminal described in the utility model is by wired or wireless mode access to LAN or wide area network.

Further say, main control end described in the utility model is by wired or wireless mode access to LAN or wide area network.

The beneficial effects of the utility model are:

1) by TCP IP agreement carry out transfer of data, (do not consider network delay) in theory, as long as computer and this device can be networked, just to use; Achieve the transmission of overlength distance.

2) do not need, at computer terminal, any new equipment is installed, only need installation driver.This driver is responsible for carrying out transfer of data (under networking situation) with book server and carrying out virtual installation to connection device.

3) extra application software is not needed just can to carry out the use of equipment, just as the same with local computer at operation local device.

4) it is two-way for controlling; If the equipment of access is the input equipment such as mouse, keyboard, that can realize the function from remote control computer, such as: teledata typing; If the equipment of access is the output equipment such as printer, sound equipment, that can realize the function of computer long-distance control external equipment, such as: remote printing.

5) much unnecessary trunking can be saved on hardware, the exploitation of a lot of Long-distance Control type systematic can be removed again from software.

Embodiment

With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, native system comprises:

1, network portion

Adopt Transmission Control Protocol, realize overlength distance signal transmission, ensure that signal is correctly stablized.Controlled terminal PC can adopt wired or wireless mode access to LAN or wide area network, and main control end (radio hardware server) adopts wifi technology to access.

2, controlled terminal

Controlled terminal, except will networking, only needs the driver installing main control end.This driver has two parts effect, and one is intercept network, and send or receive the order of main control end at any time, two is simulate corresponding hardware device, as mouse, keyboard etc. at controlled terminal.

3, main control end

Main control end core with STM32 microcontroller for processor, additional Wifi module, USB module.

For input equipment, as mouse-keyboard, the groundwork of main control end is the input instruction detecting peripheral hardware, then this instruction is encapsulated as binary data packets according to internal agreement, by wifi module by Packet Generation to controlled terminal.

For output equipment, as printer, the groundwork of main control end is the data being received controlled terminal by Wifi module, then outputs to peripheral hardware by USB module.In addition, main control end needs the thing additionally doing, installs peripheral hardware exactly, after peripheral hardware is received USB module, reads corresponding driving file, then send to controlled terminal to install by Wifi module driving file from SD card.

Native system remote operation flow process is:

1, by computer access network, can by wired or wireless wifi.

2, by this device access network, can by wired or wireless wifi.

3, by arranging software, the network parameter of this device is set, and guarantees to be communicated with computer (ping leads to).

4, peripheral hardware is connected to (by usb, serial ports etc.) in main control end.

5, install driver is to computer, and specifies the network address of this device, and scan new equipment and Auto-mounting driver, concrete steps are:

A, main control end detect usb device interrupt order (such as: keyboard knocks, mouse clicks), this interruptive command and equipment I d are encapsulated as command message, use tcp protocol transmission to the listening port of controlled terminal;

After b, controlled terminal receive this command message, according to equipment id, find corresponding virtual unit, the driver sending to virtual unit corresponding interruptive command, reach the object driving operating system.
