Abstract
This utility relates to an information display of used for petroleum explore well drilling yard consisting of a switch 1, series communication port2, a control circuit board of the screen 3, character library 4, slave circuit board 5 and LED display 6 are connected with power 1 through a lead; series communication port 2 is connected with the display main control circuit board3. Said display has advantages of small, light weight, less power, high brightness, large view angle, low cost and easy maintenance. The utility model has ability under all weathers with good visual effect under direct sunshine. A notice screen is able to work without computers, showing display circularly the content of the memory satisfying needs for different information in a drilling yard.
Description
Technical field:
The utility model relates to a kind of display device that is used for petroleum drilling exploration construction drilling well site information, belongs to LED electronic display technology.
Background technology:
In oil drilling exploration work progress, site mud logging personnel will in time provide positive drilling stratum layer position, well depth, lithology, the demonstration of oil gas water, drilling fluid density, viscosity, water injection well dynamic dispatching information for the drilling engineering personnel, also to provide blowout prevention, anti-sticking, leakproof, fault prompting such as anti-collapse in real time, to avoid occurring all kinds of engineering accidents.The means of traditional with the blackboard is media can not satisfy well site information polytrope and real-time, exist the advance notice content easily by rain drop erosion, not eye-catching, shortcoming such as do not see night, can not directly apply to the oil drilling working-yard and existing outdoor version LED display is big because of cost height, font, factor such as inconvenience is installed in the well site.
Summary of the invention:
The purpose of this utility model is to provide a kind of cost low, convenient for installation and maintenance and brightness is high, the visual angle is big, possess the all-weather ability to work, the good drilling well site information display of visual effect under sunshine direct projection condition.
The utility model is to realize like this.This kind information display is made up of Switching Power Supply, serial communication port, display screen master control borad, library stores device, secondary control circuit plate and LED display.This device links to each other with well site geologic data Acquisition Instrument main frame, during work, computing machine changes 485 photoisolators by RS232 and links to each other with the advance notice screen, data (comprising control command) are transferred to electronics geology advance notice screen governor circuit to be handled, governor circuit converts data and control command to corresponding horizontal-drive signal and sends secondary control circuit plate line scanning Drive and Control Circuit driving LED display screen dot array module again to, shows the various information that equipment such as well site geologic data Acquisition Instrument, gas instrument, comprehensive logging instrument collect in real time.The LED display display mode is flexible, has character and moves to left, moves to right etc. 16 kinds and go out the screen mode, can set out the screen mode according to actual needs arbitrarily, and screen content can be refreshed by computer real-time.
The utlity model has that volume is little, in light weight, little power consumption, brightness height, the visual angle is big, cost is low, advantage such as convenient for installation and maintenance, this device possesses the all-weather ability to work, visual effect is good under sunshine direct projection condition, the advance notice screen can work alone by divorced from computer, content in the circulation display-memory can satisfy the actual needs that drilling well site shows various information in real time fully.
Description of drawings:
Accompanying drawing is an operating circuit schematic block diagram of the present utility model.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of Switching Power Supply 1, serial communication port 2, display screen main control board 3, library stores device 4, secondary control circuit plate 5 and LED display 6, and its structure, assembled relation are as follows: serial communication port 2, display screen main control board 3, secondary control circuit plate 5, LED display 6 are connected with power supply 1 by lead respectively; Serial communication port 2 is connected with display screen main control board 3, library stores device 4; Display screen main control board 3, secondary control circuit plate 5, LED display 6 are connected to each other successively.Wherein, Switching Power Supply 1 model is SK-2, and its function is that the 220V AC power is converted to the 5V direct supply, for display screen provides stable power.Serial communication port 2 models are changeed 485 interfaces for standard RS-232, and function is to realize the communication of display screen and serial ports of computers.Display screen main control board 3 is provided with display screen single-chip microcomputer governor circuit, function is under the control circuit control that single chip computer AT 89C55 constitutes, the formed word module information that receiving computer sends, and be stored in the library stores device, give driving circuit driving LED display screen again and show.Secondary control circuit plate 5 is provided with line-scanning drive circuit, and function is that the driving LED display screen shows under the driving circuit control that single chip computer AT 89C52 constitutes.LED display 6 parameters: 16 * 16 dot matrix, 8 * 8mm, function is to adopt the form display text and the character information of superhigh brightness LED dot matrix, full screen by 6 row, 8 row totally 48 LED lattice modules forms, each type matrix is by the individual luminotron formation in 256 (16 * 16).
