The KVM can work in a harsh environment, and can realize remote control.
Description
Technical field
The utility model relates to a kind of KVM equipment, specifically a kind of reinforcing KVM.
Background technology
The IP-based digital KVM switch of widespread use now can't satisfy the request for utilization under the rugged surroundings.At first, because its main chip that adopts is the business level product, the working temperature lower limit of equipment can't reach below 0 ℃.Secondly, since KVM with respect to computing machine and server configures more keyboard and mouse, USB and display interface device, and all adopt the form of standard interface, its electromagnetic leakage is more serious with respect to general computing machine or server, and the electromagnetic compatibility problem of KVM is outstanding.Once more, common business level KVM product case does not adopt seal approach, can't work reliably and with long-term in the working environment of airborne dust, salt fog.Reinforce KVM for minority, can't concentrate the management and control function in long-range realization.
Summary of the invention
The utility model provides a kind of a kind of reinforcing KVM of reasonable in design, better performances.
A kind of KVM of reinforcing of the present utility model realizes in the following manner, the structure of this KVM comprises housing, the master control board of KVM switch, display lid, shield glass, key panel, three anti-keyboard, Rocking-bar mouse and buttons, the master control board of KVM switch, display lid, shield glass, key panel are arranged on the housing, also are provided with heater circuit and long-range switching controls module in the housing; Display lid and key panel flexibly connect by rotary gemel, and three anti-keyboards, Rocking-bar mouse and button all are fixed on the key panel.
Each unit interface adopts the connected mode of aviation connector.
Surface of contact place in key panel and display lid is provided with conductive rubber strip.
The beneficial effects of the utility model are: can normally start and continuous firing under lower temperature, have stronger anti-electromagnetic leakage function, can realize the remote centralized management and control in the medium-term and long-term work of rugged surroundings such as airborne dust, smog.

Embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description the in detail.
Embodiment: as shown in Figure 1, the structure of this KVM comprises housing 1, KVM switch master control board 4, display lid 5, shield glass 12, key panel 8, three anti-keyboard 9, Rocking-bar mouse 10 and buttons 11, KVM switch master control board 4, display lid 5, shield glass 12, key panel 8 are arranged on the housing 1, also are provided with heater circuit 2 and long-range switching controls module 3 in the housing 1; Display lid 5 flexibly connects by rotary gemel 6 with key panel 8, and three anti-keyboards 9, Rocking-bar mouse 10 and button 11 all are fixed on the key panel 8.
The heater circuit 2 that is provided with in the housing 1 is heating main chip below 0 ℃, guarantees that KVM can normally start and continuous firing under the low temperature.
Total interface is selected for use the connected mode of aviation connector.Because the aviation connection device has Electro Magnetic Compatibility, has avoided the electromagnetic leakage that is caused by interface.Can in the aviation connector, add feedthrough capacitor, improve the high frequency characteristics of wave filter.
Be provided with the good conductive rubber strip of shield effectiveness 7 at the surface of contact place of key panel 8 and display lid 5, guarantee the leakproofness of surface of contact, and wall uses the electromagnetism refraction principle to increase plane of refraction within it.The monitor signal line uses gauze screen, and along housing 1 cabling.
Do not need the place of cabling to use metal partion (metp) to carry out electromagnetic isolation.Gauze screen effective isolation high-frequency signal.Along housing 1 cabling the low-frequency disturbance on the gauze screen is unloaded and to be put on the casing.
Effectively decay interference strength between the slit of refraction principle is used in the connection of rotary gemel 6, and the interference signal intensity that gives off is weakened.
Transfer impedance between shield glass 12 and the housing 1 is low as far as possible, and transfer impedance is low more, and shield effectiveness is high more, and electromagnetic leakage is more little.
As shown in Figure 2, in order to realize long-range switching controls, use the CPU based on the ARM kernel that demonstration, keyboard and mouse and usb signal are carried out switching controls, CPU finishes local and remote handoff functionality simultaneously.Switching in this locality is by using the MUX circuit that each signal is selected.Long-range switching implementation procedure is, at first the VGA signal carried out the AD conversion, is converted to digital signal RGB, and rgb signal is done the JPEG compression, at last the JPEG signal carried out boil down to IP signal, and is sent to network by network interface card.Secondly, usb signal is carried out direct boil down to IP signal, and be sent to network.In client, receive above signal by computing machine, and utilize the keyboard and mouse of the resource main control system of computing machine, by the mouse of mouse synchro control main frame.Vision signal is moved in browser window by the Web interface.
Except that the described technical characterictic of instructions, be those skilled in the art's known technology.
