Description

A kind of SCM Based light device of transmitting messages

Technical field

The utility model relates to a kind of flashing light signalling device, specifically a kind of SCM Based light device of transmitting messages.

Background technology

Flashing light signalling, as a kind of traditional visual communication mode, has obtained extensive utilization at navigational field.Although modern radio communication has obtained great development, the feature such as flashing light signalling has that equipment is simple, easy operating, vitality are strong, is still bringing into play the important function that radio communication does not substitute.The mode that the training of signalman's light receiving at present still relies on the sudden strain of a muscle of coach's manual control signal lamp to go out transmitted signal to allow student copy and accept, this will ask coach's attentiveness high concentration, and its workload is also larger.

Summary of the invention

The technical problems to be solved in the utility model be to provide a kind of simple in structure, automaticity is high, use is flexible, the SCM Based light that reduces workload is transmitted messages device.

In order to solve the problems of the technologies described above, the SCM Based light of the present utility model device of transmitting messages, comprise and controlling and processing module, control and comprise single-chip microcomputer and the speed control switch being connected with single-chip microcomputer with processing module, link information input module on the input port of control and processing module, on the output port of described control and processing module, be connected with information display module, on the output port of control and processing module, be also connected with light sending module, described light sending module comprises voltage transitions chip and the LED lamp being connected with voltage transitions chip.

Described MIM message input module comprises keyboard and keyboard scan chip that can input data information.

Described information display module is LED display.

The utility model has the advantage of: by the control that arranges and processing module and the MIM message input module that is connected with processing module with control, information display module and light sending module, thus can be by single-chip microcomputer by the letter of keyboard input, numeral and service code are converted into corresponding Morse code, single-chip microcomputer is according to the speed that arranges to control LED lamp transmission light Morse code of speed control switch, thereby complete various letters, the work of sending of phrase and message, alleviated largely coach's working strength, reduced workload, it is simple in structure, volume is little, cost is low, automaticity is high, use flexibly, not only can on classroom, train use, can also allow student train voluntarily under class, applied range.

Accompanying drawing explanation

Fig. 1 is the transmit messages theory diagram of device of the SCM Based light of the utility model;

Fig. 2 is the SCM Based light of the utility model keyboard structure schematic diagram in device of transmitting messages;

Fig. 3 is the transmit messages transmission flow figure of device of the SCM Based light of the utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the SCM Based light of the present utility model device of transmitting messages is described in further detail.

Flashing light signalling represents letter, number, service code with various length flash of light combination.We call short light a little, and long light is called to be drawn.Time scale between dot-dash is: using and put the chronomere as Yi Ge, draw and equal San Ge chronomere, equal Yi Ge chronomere between flash of light, equal San Ge chronomere between letter, between each phrase, equal Wu Ge unit.

General Morse (Morse) code in the world, to letter and number be defined into, for example:

“A” ● —

“B” —●●●

“C” —●—●

“1” ●— — — —

“2” ●●— — —

“3” ●●●— —

In flashing light signalling process, except sending the message being formed by letter and numeral, also must send the service code for communication links, as " calling ", " promising ", " start of heading ", " ENMES ", " please retransmit " etc., these symbols are also that the various combination by length light represents.

As shown in the figure, the SCM Based light of the present utility model device of transmitting messages, comprise and controlling and processing module, control and comprise single-chip microcomputer and the speed control switch being connected with single-chip microcomputer with processing module, the function that single-chip microcomputer completes has: (1) controls the character that display module shows input; (2), after " send key " being detected and pressing, the message of input or service code are converted into a series of low and high level and are transferred to light sending module; (3) sweep speed control switch, sends code sign according to setting speed.Speed control switch is comprised of seven toggle switches, seven pins that connect respectively single-chip microcomputer, represent the transmission rate setting of 10 yards/minute to 70 yards/minute, can only there is in use a switch to be positioned at the position of " ON ", single-chip microcomputer, by the level of these seven pins of scanning, obtains sending rate control parameter; Link information input module on the input port of control and processing module, MIM message input module comprises keyboard and keyboard scan chip that can input data information, on the output port of control and processing module, be connected with information display module, information display module is LED display, the symbol of keyboard input is shown on display screen, so that check before transmission and correct a mistake; On the output port of control and processing module, be also connected with light sending module, described light sending module comprises voltage transitions chip and the LED lamp being connected with voltage transitions chip, when being output as high level from single-chip microcomputer pin, control LED lamp luminous, during for low level, LED lamp is not luminous.Voltage transitions chip is the voltage for applicable LED lamp by the level conversion from single-chip microcomputer pin.

Its using method is as follows:

(1) transmission rate is set, corresponding toggle switch is placed in to " ON " position, all the other are placed in " OFF " position;

(2) press service code or incoming message;

(3) press " transmission " key.
