Description
Technical field
The utility model relates to a kind of server control module, specifically a kind of EC control module based on single-chip microcomputer KVM system.。
Background technology
The popularizing and using more and more widely of computing machine, the workload that the thing followed administers and maintains is also increasing.The occasion that specific (special) requirements is especially arranged for security and convenience; Like the server room; If every station server all is equipped with one group of special-purpose mouse, keyboard and display, will causes wiring complicated, and bring managerial confusion easily; While is wasting space and fund also, so KVM equipment is widely used in large-scale machine room.
KVM, the i.e. abbreviation of keyboard (Keyboard), display (Video) and mouse (Mouse).The core concept of KVM technology is: through disposing suitable keyboard, mouse and display; The centralized management of realization system and network and raising manageability; Improve system manager's work efficiency, practice thrift machine room area, reduce the total cost of ownership of network engineering and server system; The radiation that also can avoid multi-display to produce, construction health environment-friendly machine room.
The appearance of KVM has solved machine room has for how many station servers, keyboard, display and the mouse of equal number just must be arranged and the cable that causes is complicated, overlapping investment causes the wasting of resources problem.Traditional KVM supervisory system realizes through hardware circuit the switching between each main frame or the server, if the port number of control is more, then the hardware commutation circuit will increase, thereby makes hardware components increases that take up room, the increase production cost.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of EC control module based on single-chip microcomputer KVM system reasonable in design, simple in structure is provided.
The utility model solves the technical scheme that its technical matters adopted: comprise single-chip microcomputer, server key mouse signals collecting end, temperature sensor signal collection terminal, server VGA signals collecting end, server key mouse control signal end, temperature signal end and server display control signal end; Server key mouse signals collecting end, temperature sensor signal collection terminal, server VGA signals collecting end, server key mouse control signal end, temperature signal end, server display control signal end are connected with single-chip microcomputer respectively.
Single-chip Controlling adopts the I2C mode bus.
Control section mainly is by the C8051F020 SCM system coherent signal to be accomplished acquisition controlling and conversion output.Wherein, Single-chip microcomputer is as the core of EC module; Its effect is as shown in Figure 1: through key mouse, VGA signal and the temperature signal of I2C acquisition server; After single-chip microcomputer inner port setting and relevant configuration, export the coherent signal of one road server, comprise demonstration and the operation of key mouse of temperature control, VGA.When temperature is lower than the working temperature of computer-internal mainboard, hard disk, display etc., send high level, drive heating arrangement, like heating film etc., give the corresponding hardware heating that needs heating; Otherwise, send low level, drive heat abstractor, like fan etc., give the corresponding hardware heat radiation that needs heat radiation.For one operation of the multiselect of multipath server, upstream and downstream button control port is set, last line unit refers to that N road server (PC) presses the order of PC0-PCN and export, on the contrary following line unit.This key assignments selects 1 code translator to output to the control port of respective server through N, and the demonstration of Control Server and key mouse are operated, and the realization multichannel is imported the control of one tunnel output.
The utility model compared with prior art, the beneficial effect that is produced is:
Demonstration and the key mouse of all-in-one are controled concentrate on the volume very little chip and module, the space of all-in-one is dwindled greatly, made things convenient for the light-weight design of all-in-one; Simultaneously, adopt wide temperature level chip and the real-time controlling Design of temperature, satisfy the temperature environment request for utilization of KVM all-in-one.

Embodiment
Below in conjunction with accompanying drawing the utility model is done following the detailed description.
Shown in accompanying drawing; The EC control module based on single-chip microcomputer KVM system of the utility model, its structure comprise single-chip microcomputer 1, server key mouse signals collecting end 2, temperature sensor signal collection terminal 3, server VGA signals collecting end 4, server key mouse control signal end 5, temperature signal end 6 and server display control signal end 7; Server key mouse signals collecting end 2, temperature sensor signal collection terminal 3, server VGA signals collecting end 4, server key mouse control signal end 5, temperature signal end 6, server display control signal end 7 are connected with single-chip microcomputer 1 respectively.
The I2C mode bus is adopted in single-chip microcomputer 1 control.
This EC module is except that core C8051F020 single-chip microcomputer; What also comprise control VGA demonstration shows the OSD chip at screen; The temperature sensor LM75 that is used for temperature acquisition, the eeprom chip 24LC02 of key mouse signal output control, server channels is selected control chip PCA9555 etc.Single-chip Controlling adopts the I2C mode bus; As shown in Figure 2; The DATA of keyboard and mouse and CLK signal are input in the control module through the P0.2～P0.5 of single-chip microcomputer; After internal configurations, the PS2 signal at first is stored among the EEPROM, treats outputing to the output of external bond mouse port after server is triggered; P0.1 and P0.1 are respectively the SCL clock and the SDA data-signals of osd control circuit; Output to osd circuit; The demonstration of control VGA; P2.4～P2.6 output DDCSEL shows the identification control signal simultaneously, realizes the identification control of display resolution and refresh rate, shows with the image that adapts to different display devices.Adopt the LM75 temperature sensor of the total line traffic control of I2C to gather complete machine temperature information in addition, carry out temperature and control in real time, satisfy the wide temperature working environment of KVM all-in-one.In order to debug conveniently, the P3 port is set exports corresponding pilot lamp control signal, realize that power switch shows and the demonstration of KVM switching state.
Except that the described technical characterictic of instructions, be this professional's known technology.
