Description

The ship collision prevention sound and light signal device of computer control

The utility model belongs to the sound and light signal device, particularly the boats and ships sound and light signal device of computer control.

China marine site is vast, and rivers and lakes spread all over, and inland river and coastal vessel are assorted many, crash easily during navigation.Therefore Ministry of Communications began to carry out " boats and ships inland river collision prevention sound and light signal rule " in 1992, and regulation is expressed the various state requirements of boats and ships by 20 kinds of length acoustical signals.There are various control methods to obtain above 20 kinds of signals, have the artificial memory to control, computer control is also arranged, and contact and contactless control are arranged.Manual control and people's psychological condition, health status, skills involved in the labour are closely related, so error easily.Contact control has the spark sound to produce, contact meeting galvanic corrosion, thus oxidation causes system running state to worsen even error.Equipped sound number device is propagated single acoustical signal for main frame on the ship drives cylinder body type air compressor pump in the boats and ships at present, and serviceable life is short, and complex structure, huge, accident rate height, cost height, and maintenance is extremely inconvenient.

It is a kind of by computer control that the purpose of this utility model is to provide, easy and simple to handle accurately, siren is simple in structure, power consumption is little, the ship collision prevention sound and light signal device of long service life.

The purpose of this utility model is realized by following technical scheme:

The utility model computer control ship collision prevention sound and light signal device is made up of three parts: the microcomputer singlechip control section; The optical signal device part; Miniature energy-conservation adjustable siren mechanism part.The microcomputer singlechip control section comprises keyboard, single-chip microcomputer, display, interface circuit, photoelectricity isolated gate trigger, fet power amplifying circuit.It is to produce 20 kinds of collision prevention signals automatically with the micro computer programming, carries out power amplification with power field effect pipe, thus the spark of having avoided the contact to produce, and controller adopts eight 89c51 single-chip microcomputers and SMP60NO6 field effect transistor.By chip 8155 the key signal is imported into single-chip microcomputer 89c51 the signal of the position of each key of reflection is become identical electric signal of acoustic frequency duration, through the grid control circuit of photoelectric isolating device 4N25 to the SMP60N06 field effect transistor, the grid controlling circuit that is made of triode 9012,8050,8550 removes the signal shaping amplification that single-chip microcomputer comes to promote field effect transistor SMP60N06, field effect transistor can directly drive electroluminescent lamp and send the 600W flash of light, starts miniature energy-conservation adjustable siren sounding simultaneously.Above-mentioned miniature energy-conservation adjustable siren mechanism is made up of direct current generator, vane pump, air receiver lid, volume adjuster, sounding copper sheet, acoustic horn.The eccentric protecgulum of motor links to each other, is equipped with the unloading rotor in three-flute three holes on the main shaft of direct current generator with pump housing rear end, rotor has three blades that slide in the blade groove of pitch angle, have vane pump gas off-take and vane pump air entry at blade pump casing, pump housing front end is equipped with sphere end cap and sounding copper sheet and air receiver lid and connects one, and volume adjuster is equipped with in air receiver lid exit.

The new ship collision prevention sound and light signal computer controller of this practicality is owing to adopt the key button control signal to take place, simple to operate, be difficult for going wrong, miniature energy-conservation adjustable siren has adopted the structure of uniform three unloading holes of rotor end-face, reduces the air pressure of the blade and the pump housing, guarantees that two airtight limits of blade contact with pump housing inside surface is fine, the wearing and tearing between the blade and the pump housing have been reduced, also just reduce load, saved electric weight, improved the effect performance and the life-span of miniature energy-conservation adjustable siren mechanism.

Be further described below in conjunction with drawings and Examples:

Fig. 1 is a ship collision prevention sound and light signal device circuit schematic diagram.

Fig. 2 is an energy-conservation adjustable electric air pressure sound equipment mechanism structural representation.

An embodiment of the utility model computer control ship collision prevention sound and light signal device comprises microcomputer singlechip control section, sound and light signal device part and miniature energy-conservation adjustable siren part.Above-mentioned computer Single-chip Controlling part is by keyboard, single-chip microcomputer, display, interface circuit, photoelectricity isolated gate trigger, the fet power amplifying circuit is formed, keyboard is made up of 20 keys, wherein with Chinese mark signal name, the position that shows charactron display button button, by 0～19 totally 20 numerals form.By chip 8155 the key signal is imported into single-chip microcomputer 89c51 the signal of the position of each key of reflection is become identical electric signal of acoustic frequency duration, through the grid control circuit of photoelectric isolating device 4N25 to the SMP60N06 field effect transistor, constitute grid controlling circuit by triode 9012,8050,8550, the signal shaping amplification that single-chip microcomputer comes is removed to promote field effect transistor SMP60N06, field effect transistor can directly drive the flash of light that electroluminescent lamp sends 600W, starts miniature energy-conservation adjustable siren mechanism sounding simultaneously.Above-mentioned energy-conservation adjustable siren comprises 24V, 150W direct current generator 9, the eccentric protecgulum 11 of motor links to each other with the rear end of the pump housing 6, the unloading rotor 7 in three-flute three holes is housed on the main shaft of direct current generator 9, rotor has three blades 8 that slide in the blade groove of pitch angle, vane pump is provided with gas off-take 5 and air entry 10, pump housing front end is equipped with sphere end cap 4 and sounding copper sheet 3, and air receiver covers 2 exits volume adjuster 12 and acoustic horn 1 are housed.Blade pump casing adopts high-phosphorous iron to form unloading rotor and blade adopts nonmetallic materials through Ageing Treatment through grinding, can be under-20 ℃ of-160 ℃ of environment operate as normal.
