The server liquid crystal display of prior art is all share same feed circuit with server itself, and when power supply breaks down, server itself and liquid crystal display all can occur power down, cause the loss of related data; If need when maintenance personal keeps in repair to reorientate trouble spot, process very complicated and also workload huge, cause maintenance efficiency lower.Based on this, a kind of accurate positioning is now provided, supports the liquid crystal screen control circuit of off-line display.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides the liquid crystal screen control circuit that a kind of structure is simple, result of use is desirable, support off-line shows.
The technical solution of the utility model realizes in the following manner, a kind of liquid crystal screen control circuit supporting off-line to show, comprise programmable single chip computer on power supply, liquid crystal display and sheet, described power supply accesses programmable single chip computer on liquid crystal display and sheet after sequentially passing through a diode, the first metal-oxide-semiconductor respectively; On this sheet, programmable single chip computer is directly connected with above-mentioned liquid crystal display by universal serial bus.
The diode output that described power supply connects also is connected with super capacitor, and power supply is powered for this super capacitor; Described super capacitor is by being divided into two branch roads after DC voltage changer: programmable single chip computer on a direct brace in road, another road accesses programmable single chip computer on liquid crystal display and sheet respectively after the second metal-oxide-semiconductor.
In technique scheme, by the setting for subsequent use of super capacitor, under making whole system power-down conditions, still can maintain the normal work of liquid crystal display, practical.
Further, described power supply and sheet are also provided with monitoring management module between programmable single chip computer, this monitoring management module connects programmable single chip computer in sheet above by RS232 signal wire, I2C bus, Reset signal wire.This monitoring management module can be used for carrying out analyzing and positioning to the system failure fast, thus makes staff can find problem source as early as possible, and what maintain easily carries out smoothly.
As preferably, described monitoring management module also connects log memory, and the output terminal of this log memory is divided into two branch roads, programmable single chip computer on a road brace, and another road connects the output terminal of DC voltage changer.The monitor message such as configuration, state, fault, warning that log memory comes for preserving monitoring management module real-time Transmission, thus make maintainer's off-line when safeguarding view relevant information, thus fast analyzing and positioning is carried out to the system failure.
In sum, the beneficial effect that the utility model is compared with prior art produced is:
A kind of liquid crystal screen control circuit supporting off-line to show of the present utility model has the features such as structure is simple, easy to use, novel, after the unexpected power down of server system, this control circuit can control liquid crystal display and continue normal work, now super capacitor starts, and completes the power supply to whole system, the relevant configuration information of display system and fault alarm information, be convenient to carry out analyzing and positioning to the system failure fast, integral manufacturing is with low cost, practical, is easy to promote.
