KVM interface 102, for the KVM port that is connected to by the KVM connecting line on the server, and support local mouse, keyboard and the display of connecting, operational order arrives each server by this KVM interface 102 and realizes monitoring, and the keyboard-video-mouse signal that reception server passes over (KVM signal), this KVM signal is electric signal normally, can directly send administration module 103 to.KVM interface 102 can be the interface of 15 pins (pin) usually.
Administration module 103, be used for receiving described status information and described keyboard-video-mouse signal, and according to status information, keyboard-video-mouse signal and steering order generation power operation instruction and keyboard-video-mouse operational order, the power operation instruction is used for the upper and lower electricity operation of each socket on the control intelligent power insert row, and the keyboard-video-mouse operational order is used for by KVM interface 102 each server being monitored and being managed.
Specifically comprise: administration module 103 inquires about and preserves the upper and lower electric situation of each socket on the described intelligent power insert row in real time by polling mechanism; After arriving from the make-and-break signal of power module 101, power signal, administration module 103 utilizes the algorithm that sets in advance to calculate the socket of these power module 101 correspondences as the output power of power input end mouth according to described power signal, and obtains the current on off operating mode of socket according to make-and-break signal.
Administration module 103 is received described KVM signal, utilizes the algorithm that sets in advance that this KVM signal is handled, and is sent to control desk or control terminal by network, thereby realize KVM over IP function.
Administration module 103 also is connected with control desk or control terminal, this control desk is shown as browser interface to the long-distance user, it for example can be a WEB page, the long-distance user is by this control desk of ethernet access, each socket power supply state of remote monitoring, output power, and send steering order as required.Control terminal can be a common computer.
Administration module 103 can be divided into a plurality of modules according to each function for realizing above function, and the principle of work of a preferred embodiment specific descriptions administration module 103 is provided among the present invention,
As shown in Figure 2, administration module 103 comprises: signal switch unit 1031, network element 1032, control module (MCU) 1033, buffer unit (RAM) 1034 and communication unit 1035; Wherein, centered by control module 1033, be connected with described signal switch unit 1031, network element 1032, buffer unit 1034 and communication unit 1035 respectively.
Signal switch unit 1031, be used for the KVM signal that receives is switched, specifically comprise: different steering orders is that the user sends at different servers, after steering order arrives administration module 103 and generates the keyboard-video-mouse operational order, by signal switch unit 1031 this keyboard-video-mouse operational order circuit is switched to specific server.
Network element 1032 is used for being connected with Ethernet, and provides the built-in browser interface by this connection; For example can pass through the built-in network interface 104 of intelligent insert row, be connected to outside Ethernet to realize KVM-over-IP, namely, ICP/IP protocol based on industrywide standard, come operational administrative that multiple servers is concentrated by internet or Web by the switching between server, reduced the quantity of cable to greatest extent.Described network interface 104 adopts the RJ45 interface usually.
Control module 1033, be used for being built-in with different multiple algorithms, signal from power module 101, KVM interface 102 is calculated result of calculation, and according to the result of calculation of described status information and keyboard-video-mouse signal, and from user's steering order generating run instruction; Operational order is divided into two kinds: the keyboard-video-mouse operational order, in order to by described keyboard-video-mouse interface described server is controlled; The power operation instruction is in order to come the break-make of Control Server power supply by the relay circuit in the power module 101.
Buffer unit 1034 is used for buffer memory and comes by signal switch unit 1031 transmission, from the KVM signal of KVM interface 102.Can also be used for make-and-break signal and the status information that buffer memory obtains by power module 101.
Communication unit 1035 is used for communicating with each power module 101, obtains the current status information of power supply and transmits user's steering order.
The intelligence insert row also remains with keyboard-video-mouse switching interface 105, is used for realizing local mouse, keyboard and the display of connecting, and the state of each server is checked.
More than described inner structure, function and the principle of work of intelligent insert row, in practical work process, as shown in Figure 3, its concrete course of work is as follows:
Step 301. administration module 103 powers on and carries out the initialization self check;
After the step 302. self check success, each power module 101 and KVM interface 102 are carried out server power supply and KVM address detected, and arrange accordingly.
Step 303. detects the presence of current each server in real time, if the server that has inserted or deleted before detecting, system can reaffirm the KVM address state of this server.
Step 304. administration module 103 obtains and preserves status information and the KVM signal of every station server by polling mechanism.
Step 305. user has imported steering order by control terminal or control desk, administration module 103 is transferred to corresponding with service device by interruption or polling mechanism with the keyboard-video-mouse operational order in the described operational order according to this steering order generating run instruction; If the power operation instruction then directly arrives the relay circuit in the power module 101.
Such as steering order in order to operate the KVM of certain station server, perhaps switching on and shutting down etc., the operational order that generates of this server this steering order from administration module 103 that execution is received then, and the result returned administration module 103.
Use the technology that the above preferred embodiment of the present invention provides, by in intelligent insert row, increasing an administration module 103, all power modules 101 and KVM interface 102 all are connected with this administration module 103, saved the cost that drops into hardware devices such as KVM switch, connecting line shortens, and has saved the network layout resource; Simultaneously administration module 103 provides remote management console, can each power port state of remote monitoring, and control KVM by this control desk, and being convenient to centralized management, can monitor in real time power supply, can carry out the KVM operation to server by platform again.Simultaneously, KVM OverIP function that administration module 103 inside are integrated, use an IP address, come telemanagement power supply and KVM by mixed-media network modules mixed-media, realize that KVM switches and the scheme of power management one, the electric power thus supplied that both can check current power supply by an IP network port on it, the power that uses, can realize the KVM function again, namely save Internet resources, be convenient to centralized management again.
Should be noted that above preferred embodiment is only unrestricted in order to technical scheme of the present invention to be described, all parameter values can be according to the actual conditions adjustment, and in this rights protection scope.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spiritual scope of technical solution of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
