Description
Technical field
The present invention relates to computer long-distance control correlative technology fields, refer in particular to a kind of multi-environment remote based on relay
Process control system and method.
Background technique
Long-range control is to be left away to control another computer (quilt by a computer (main control end/client) long distance on network
Control end/server end) technology.User can be safeguarded and be managed to the computer of distal end by using tele-control system
Reason.Using computer remote control system, telecommuting, remote technology support, remote communication, remote maintenance and pipe may be implemented
The multiple functions such as reason.
The connection type of main control end and controlled terminal based on relay: main control end disposes USB(Universal Serial
Bus) relay APP(Application), main control end is connected to controlled terminal by USB relay, and USB relay passes through port
It is connected to controlled terminal, a USB relay port is correspondingly connected with a controlled terminal, and there is number in each port, and main control end passes through
The controlled terminal that the number identification of USB relay APP needs to operate.
Remote controlled manner based on relay: the IP(Internet that tester passes through main control end in distal end
Protocol) and login password logs in main control end, and then main control end manually controls USB relay by USB relay APP
Port numbering control controlled terminal.
There are the drawbacks of: 1) corresponding relationship of long-range control main control end and controlled terminal is 1:1 at present, can not achieve multiple masters
Control end is operated in synchronization to the same controlled terminal and synchronization is there are when multiple distal ends, only one distal end is effective.
2) it is not logged on main control end to be unable to complete to controlled terminal operation, only login main control end could operate controlled terminal.It is multiple when having
When main control end needs to log in, need to remember the IP and password of multiple main control ends, at the same will manual entry main control end one by one, hand
Move cumbersome, memory difficulty.3) for large-scale controlled terminal group, there are a large amount of USB relays, each USB relay has multiple again
Port numbers, tester is easier to obscure USB relay port numbers in test process, easy to operate by mistake to cause test result inaccurate
Really, stagnation is brought to entire testing progress；More importantly USB relay end is operated manually, every time to tester
It goes to search USB relay port numbers, then corresponding controlled terminal could be operated, efficiency is extremely low.4) traditional long-range
Controlling main control end basic configuration is a host, a display, necessary peripheral hardware.When main control end demand becomes larger, due to
Needing to log in main control end could operate, so needing to buy more display, peripheral hardware, could complete actual effect, cause cost
Rising and resource waste.5) tradition can not achieve automatic operation based on the Telnet of USB relay, need operator
Member logs on to main control end, then manually controls controlled terminal to USB relay APP, causes working efficiency low.
