Abstract
The utility model relates to a portable keystroke display panel which is characterized by comprising a patch singlechip, an LED display screen, an LED drive circuit, keystrokes and a serial port socket, wherein, the I/O (input/output) ports of the singlechip are respectively connected with the input end of the LED display screen, the base electrode of a triode and the keystroke output ends; and the pin of the singlechip sending and receiving data is connected with the universal serial port. In the utility model, a serial data bus is connected with a double-shaft solar energy tracking main control panel, so the LED display screen can locally display the time as well as latitude and longitude information; and the setting and modification for the time as well as the latitude and longitude are realized only through three keystrokes. After the modification to one main control panel is completed, the modification to the next can be performed. The keystroke display panel is portable and can achieve the plug-and-play effect; and besides, compared with the method that a human-computer interface and remote communication are integrated on the main control panel, the cost is saved.

The utility model content
The utility model provides a kind of portable button display board to the defective that prior art exists, and can link to each other with the controller main frame that is complementary at any time to regulate relevant information, and is easy to use, reduces cost.
For this reason; The utility model is taked following technical scheme: a kind of portable button display board; It is characterized in that comprising paster single-chip microcomputer, LED display, led drive circuit, button and serial ports socket; The I/O port of said single-chip microcomputer links to each other with LED display input end, transistor base and button output terminal respectively, and said single-chip microcomputer sends data and links to each other with universal serial port with the pin that receives data.Portable display board is followed the tracks of master control borad through general serial data bus and double-shaft solar and is linked to each other and realize communicating by letter, and reads, modification time and latitude/longitude information.Adopt LED display to show time and latitude/longitude information, adopt button modification time and latitude/longitude information, offer button display board power supply by master control borad through universal serial bus.
As preferably, described single-chip microcomputer adopts paster AT89C51, and led drive circuit adopts paster 8550, and LED display adopts 8 sections charactrons.
As preferably, adopt 6 charactrons, show 6 bit widths the time, branch, second information, the latitude/longitude information of 6 bit widths, 1 bit sign wherein, 5 bit data.
As preferably, between the Hour Minute Second of time showing decimally at interval, interval decimally between the degree that lat/longitude shows divides.
As preferably, in the longitude show state, sign bit does not have demonstration during the expression east longitude, and sign bit is a negative sign during expression west longitude, and in the latitude show state, sign bit does not have demonstration during the expression north latitude, and sign bit is a negative sign during expression south latitude.
As preferably, described button comprises increases key, reduce key and acknowledgement key.
The portable display board of the utility model is followed the tracks of master control borad through serial data bus and double-shaft solar and is linked to each other, and can show time and latitude and longitude information on the spot through LED display, only realizes time and longitude and latitude are set and revises through three buttons.After the modification of accomplishing a master control borad, can also make amendment to next master control borad again, easy to carry, plug and play, the way of integrated man-machine interface and telecommunication is more practiced thrift cost on master control borad.
