Abstract
The utility model provides a technical scheme of a light-emitting diode (LED) time control device. The LED time control device comprises an LED electronic screen and a control device which is connected with the LED electronic screen. The control device comprises a line drive circuit and a row drive circuit, wherein the line drive circuit is connected with the LED electronic screen, the line drive circuit and the row drive circuit are connected with a microprocessor, and the microprocessor is further respectively connected with a temperature sensor, a clock module, a wireless receiving module, a word stock module, an acousto-optic alarm module, a secure digital (SD) card communication connection module, a serial port communication connection module and the like. Provided with functions such as remote control timekeeping, timing, and reset, the LED time control device is capable of freely adjusting the time of timekeeping and timing, timely displaying the information such as current date, time and temperature, and achieving various display effects such as upward, downward, leftward and rightward rolling of Chinese characters and pictures. According to the LED time control device, personal computer (PC) serial port communication is utilized in data updating, and therefore display information can be updated through the SD card when the LED time control device is off-line.
Description
Technical field
The utility model relates to a kind of LED timed unit.
Background technology
State's economic development is swift and violent; Propagation to information has increasingly high requirement; The LED electronic display is brilliant with its color; Big display message amount, the life-span is long, power consumption is little, in light weight, characteristics such as bulk is little, stability is high, easy operating, installation and maintenance, will in socio-economic development, play the part of more and more important role.Its advantage: brightness is high, WV is low, power consumption is little, microminiaturized, be easy to concentrate Circuit Matching, drive simple, the life-span is long, shock-resistant, its application of stable performance more and more widely.Under the situation such as oratorical contest in the practical work life, reply in limited time, counting demonstration; The content statement is accomplished in requirement in official hour; Reminded by the special messenger when overtime, often effect is unsatisfactory, and the demonstration of various athletic competition marks realizes through the wire communication mode with control; Not very convenient, this is the existing in prior technology weak point.
Summary of the invention
The purpose of the utility model is exactly not enough to existing in prior technology, and provide a kind of technical scheme of LED timed unit, the device of this scheme have the remote control timing, regularly, reset, function such as timing, arbitrarily during accommodometer, timing; Information such as current date, time, temperature can be shown timely, the multiple display effects such as upper and lower, left and right rolling of Chinese character and picture can also be realized.And the LED double-sided display can be adjusted two angles between the dot matrix, makes things convenient for the user from two visual angle viewing information, and the Data Update of this device adopts the PC serial communication, also can pass through the real-time update displayed content of SD card after the off line.
This programme is realized through following technical measures: a kind of LED timed unit; Comprise the LED electronic display; The control device that is connected with the LED electronic display; The characteristics of this programme are: described control device comprises horizontal drive circuit and the column drive circuit that is connected with the LED electronic display; Described horizontal drive circuit is connected with a microprocessor with column drive circuit, and described microprocessor also is connected with temperature sensor, clock module, wireless receiving module, character base module, sound and light alarm module, SD cartoon letters link block, serial communication link block, keyboard respectively.Described microprocessor can also be connected with alarm, and described LED electronic display is two, and described two LED electronic displays are fixed on the coupling shaft.Described microprocessor is C8051F020.Described clock module is the DS1302 chip.Described temperature sensor is DS18B20.Described wireless receiving module is the PT2272 chip.Described character base module is the GT21L16S2W chip.
The beneficial effect of this programme can learn according to the narration to such scheme, because temperature sensor can detected temperatures sometimes in this scheme, and is delivered to microprocessor with temperature information, comes out through the LED electronic display screen displays; Clock module can computing time, is beneficial to the user and observes, arranges the time; Character base module can provide corresponding character library information, makes things convenient for the LED electronic display screen displays; The sound and light alarm module can be reported to the police when getting into countdown, reminds the user to note the time; The serial communication link block can communicate with computing machine, has SD cartoon letters link block can under off-line state, carry out the renewal of information; Wireless receiving module can receive controlled in wireless information, and the user is through wireless transport module, the duration of can controlled in wireless setting; Countdown begins; Timing finishes the cancellation of sound and light alarm etc., and two LED electronic displays are fixed on the coupling shaft, like this can a plurality of user's viewing information.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
