Abstract
The invention discloses a server state detection method applied to a KVM system. According to the method, an HSYNC signal in VGA signals is sampled and analyzed by utilizing a KVM system clock to judge a state of a server in the KVM system. The method has the characteristics of real-time monitoring, easiness for integration in an OSD menu and the like; the real-time state of each server can be visually obtained from the OSD menu and provided for a user to select a server channel; and the method has a wide application prospect.
Description
Technical field
The present invention relates to technical field of integrated circuits, be specifically related to a kind of server state detection method being applied to kvm system.
Background technology
KVM is the abbreviation of keyboard (Keyboard), display (Video), mouse (Mouse).The core concept of KVM technology is: by the configuration of suitable keyboard, mouse, display, realizes the centralized management of System and Network; The manageability of raising system, improves the work efficiency of system manager; Save the area of machine room, reduce the total cost of ownership of network engineering and server system; Avoid the radiation using multi-display to produce, the machine room of construction health environment-friendly.Utilize KVM many mian engine changeover system, system manager can carry out switching by a set of keyboard, mouse, display and implement management between the main frame or server of multiple different operating system.
Kvm system can realize controlling multiple servers with a set of keyboard, display, mouse, the state of multiple servers just needs to come Real-Time Monitoring, otherwise when removing switching server passage by kvm system, cannot know which is in off-position, which is in normal operating conditions.
Summary of the invention
The technical problem to be solved in the present invention is: the object of the invention is to provide a kind of server state detection method being applied to kvm system, can from the abbreviation of OSD(on-screendisplay, i.e. screen menu type regulative mode) know the real-time status of each station server in menu intuitively, carry out choosing of server channels for user.
The technical solution adopted in the present invention is:
Be applied to a server state detection method for kvm system, described method utilizes kvm system clock to the HSYNC signal sampling analysis in VGA signal, and then judges the state of the server in kvm system.
Described method specific operation process is:
In the test macro be made up of keyboard, mouse, display, kvm system and multiple servers, for wherein each server channels:
The HSYNC sampling of system clock to VGA signal obtains HSYNC1;
Again sampling is carried out to HSYNC1 and obtain HSYNC2;
HSYNC1 and HSYNC2 carry out logic with or obtain the reset signal RESET_N of counter cnt, reset counter cnt at the rising edge of HSYNC signal and negative edge, when regulation CNT count down to T, counting remains unchanged, and in other situation, counter cnt adds 1;
Judge the current state STATUS of server according to the value of counter cnt: if CNT has count down to T, illustrate in time T, the HSYNC signal of this server never changes;
Choose appropriate T, make T be greater than the cycle of HSYNC when server normally works, so having count down to T, STATUS is 0, and server is in closed condition, and in other situation, STATUS is 1, and server is in running order.
Described detection method is in OSD menu, server numbers in order, a status lamp is set after each server sequence number, the bright expression server work of lamp, lamp goes out expression server closing, show which station server very intuitively and be in closed condition, which station server is in running order, is easy to user operation.
Beneficial effect of the present invention is:
The present invention has real-time monitoring, is easy to be integrated in the features such as OSD menu, can know the real-time status of each station server intuitively, carry out choosing of server channels for user, have broad application prospects from OSD menu.
Accompanying drawing explanation
Fig. 1 is the server state monitoring of environmental figure that the present invention is applied to kvm system;
Fig. 2 is status monitoring sequential chart of the present invention.
Embodiment
Below by Figure of description, in conjunction with embodiment, the present invention is further described:
Embodiment 1:
Embodiment 1:
Be applied to a server state detection method for kvm system, described method utilizes kvm system clock to the HSYNC signal sampling analysis in VGA signal, and then judges the state of the server in kvm system.
Embodiment 2
As shown in Figure 1, on the basis of embodiment 1, described in the present embodiment, method specific operation process is:
In the test macro be made up of keyboard, mouse, display, kvm system and multiple servers, for wherein each server channels:
The HSYNC sampling of system clock to VGA signal obtains HSYNC1;
Again sampling is carried out to HSYNC1 and obtain HSYNC2;
HSYNC1 and HSYNC2 carry out logic with or obtain the reset signal RESET_N of counter cnt, reset counter cnt at the rising edge of HSYNC signal and negative edge, when regulation CNT count down to T, counting remains unchanged, and in other situation, counter cnt adds 1;
Judge the current state STATUS of server according to the value of counter cnt: if CNT has count down to T, illustrate in time T, the HSYNC signal of this server never changes;
Choose appropriate T, make T be greater than the cycle of HSYNC when server normally works, so having count down to T, STATUS is 0, and server is in closed condition, and in other situation, STATUS is 1, and server is in running order, as shown in Figure 2.
Embodiment 3:
On the basis of embodiment 1 or 2, detection method described in the present embodiment is in OSD menu, server numbers in order, a status lamp is set after each server sequence number, the work of lamp bright expression server, lamp goes out expression server closing, shows which station server very intuitively and is in closed condition, which station server is in running order, is easy to user operation.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
