technical field:
The utility model relates to a kind of information display, particularly relates to a kind of liquid crystal display monitor message touch panel device.
background technology:
In order to ensure the safety of operation power; people arrange a lot of watch-dogs on the line; all watch-dogs are all connected with the computer monitor machine of Control Room; once have an accident; computer monitor machine just can be quoted various switches, guard signal; but because picture is little, information rolling amount is large, need to check one by one, affect accident judgement speed.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple and practical, fast the liquid crystal display monitor message touch panel device of failure judgement scope.
The technical solution of the utility model is: a kind of liquid crystal display monitor message touch panel device, comprise GPRS module, RX-8025 real-time clock, LED display control card, FLASH reservoir, LED display screen body, central controller CPU, described central controller CPU controls GPRS module, GPRS module is downloaded needed data from main website, then deposit data in FLASH reservoir, central controller CPU controls LED display control card, the information of downloading is sent out from adjusting in FLASH reservoir, in LED display, shielded on body and show.
Described RX-8025 real-time clock provides concussion pulse for central controller CPU.The operating voltage of described central controller CPU is 5V.LED display control card and LED display screen body are undertaken unidirectional connected in series by RS232 interface.
Described GPRS module is connected by RS485 interface with central controller CPU.Described RX-8025 real-time clock, LED display control card, FLASH reservoir are connected by RS232 interface with central controller CPU.
Described GPRS module, RX-8025 real-time clock, LED display control card, RS232 interface, FLASH reservoir, RS485 interface are all that bidirectional linked list is connected with central controller CPU.Described 5V power supply and central controller CPU are unidirectional connected in series.
The beneficial effects of the utility model are:
1, the utility model shows that information format is larger, is easy to information to observe.In addition, large display screen shows main data message, is easy to the operation conditions of equipment to judge.
2, the utility model adopts low voltage power supply, safe, energy-conservation.And employing computer controlled automatic, shows needed data automatically, save manpower.
3, the utility model is simple and practical, failure judgement scope fast, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing explanation:
Fig. 1 is the structural representation of liquid crystal display monitor message touch panel device.
embodiment:
Embodiment: referring to Fig. 1.
The utility model is as control center by central controller CPU, 5V power supply carries out unidirectional connection by RS232 interface with central controller CPU, and for this is novel, provide voltage, central controller CPU controls GPRS module, GPRS module is downloaded needed data from main website, then deposit data in FLASH reservoir, central controller CPU controls LED display control card, the information of downloading is sent out from adjusting in FLASH reservoir, in LED display, shielded on body and show.
GPRS module is connected by RS485 interface with central controller CPU, and RX-8025 real-time clock, LED display control card, FLASH reservoir are connected by RS232 interface with central controller CPU.
GPRS module, RX-8025 real-time clock, LED display control card, RS232 interface, FLASH reservoir, RS485 interface are all that bidirectional linked list is connected with central controller CPU.LED display control card and LED display screen body are undertaken unidirectional connected in series by RS232 interface.
The utility model can show the main signals such as certain station circuit breaker position, load trend, busbar voltage, line voltage distribution, frequency information inquiry in the large-scale LCDs of centralized control center, gets final product failure judgement scope fast directly perceived, is conducive to accident treatment.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
