Abstract
An audible and visual alarm specialized for a shielding door system comprises an outer interface circuit which is connected with a sliding door, an emergency door or an end door. The outer interface circuit transmits a state signal which is acquired from the sliding door, the emergency door or the end door to a single-chip microcomputer control circuit. The single-chip microcomputer is connected with a clock circuit, a power converting circuit and a display alarm circuit. According to the audible and visual alarm specialized for the shielding door system, a mature single-chip microcomputer is used as a control chip and can be simultaneously used on the sliding door, the emergency door and the end door units of the shielding door system. Furthermore, according to the audible and visual alarm specialized for the shielding door system, two functions of light reminding and sound alarm are effectively combined; an ultra-bright LED is used as a light source; and the audible and visual alarm realizes energy saving and long service life.
Description
Technical field
The utility model relates to a kind of warning device that is applicable to urban railway system platform shielding door system, and shield door industry all can be used this acoustic-optic alarm.
Background technology
Urban railway system platform shielding door can play the effect that ensures passenger safety, control station environment temperature, shielding train noise, is widely applied in recent years.In screen door, sliding gate, escape door and three kinds of unit of end door are all provided with state acoustic-optic alarm, but user is different to their warning demand, at present, acoustic-optic alarm is according to requirement separately, adopt hardware circuit design separately, such product does not possess versatility, possesses programing function yet, causes the defect of the dumb aspect of functionality change.
Summary of the invention
The acoustic-optic alarm that the purpose of this utility model is to provide that a kind of compatibility is strong, all can use on the sliding gate at screen door, escape door and end gate cell simultaneously.
For achieving the above object, the utility model is by the following technical solutions:
The special-purpose acoustic-optic alarm of a kind of screen door, it comprises the external interface circuit being connected with sliding gate, escape door or end door, external interface circuit sends the status signal collecting from sliding gate, escape door or end door to single chip machine controlling circuit, and single chip machine controlling circuit is connected with clock circuit, power-switching circuit and Display and Alarm Circuit.
Described single chip machine controlling circuit is also connected with reset circuit.
Described external interface circuit, single chip machine controlling circuit, clock circuit, power-switching circuit and reset circuit are all arranged on feature board, and feature board is arranged on base; Display and Alarm Circuit is arranged on display board, and display board is provided with lampshade outward.
Described lampshade is for adopting the lampshade of engineering PC material, and base is for adopting the base of PBT material.
The utility model that adopts technique scheme, adopts ripe single-chip microcomputer as control chip, on sliding gate, escape door and the end gate cell of screen door, all can use simultaneously, compatible strong; Secondly, the utility model is by light prompt and two kinds of effective combinations of function of audible alarm, and ultra-bright LED is as light source, energy-conservation, and the life-span is long; The length of alarm lamp housing transverse edge is greater than the length of longitudinal edge, integral body is sleeping vertical shape and is fixed on shield door, lampshade protrudes from the surface of a body, unique appearance design and flexibly control performance, facilitate platform staff or driver under farther distance or the dim ambient conditions of vision, clearly to see the show state of alarm clearly.

Embodiment
As shown in Figure 1, the special-purpose acoustic-optic alarm of screen door in the utility model is arranged on each sliding gate, escape door, the end door place of screen door, it comprises the external interface circuit being connected with sliding gate, escape door or end door, external interface circuit sends the status signal collecting from sliding gate, escape door or end door to single chip machine controlling circuit, and single chip machine controlling circuit is connected with clock circuit, power-switching circuit and Display and Alarm Circuit.In addition, single chip machine controlling circuit is also connected with reset circuit.
Consider the limitation of status indicator lamp installation dimension, design two circuit boards: display board and feature board.Between display board and feature board, adopt direct plugging member to connect.In Fig. 2, be the circuit theory diagrams of display board and feature board.Wherein, in display board, LED connection in series-parallel mix to connect, and not only succinctly but also safety, is guaranteeing that under the prerequisite of high brightness, light was evenly distributed on the lampshade of status indicator lamp.Main circuit on feature board will comprise clock circuit, reset circuit, power-switching circuit, external interface circuit, internal interface circuit and single chip machine controlling circuit.Single-chip microcomputer is selected the high STC12C2052 of cost performance on market, has not only guaranteed product quality but also reduced cost.General external interface guarantees that sliding gate, escape door and end door status alert device all can use with a product, and photo-coupler is isolated mutually input and output, has good electrical isolation and antijamming capability.
The course of work of the present utility model is: sliding gate sound and light alarm signal follows the order of door control unit control panel switch gate to carry out corresponding warning; The status alert device demonstration of dividing right and left on escape door, when escape door is opened, pilot lamp Chang Liang, buzzer warning; When end door is opened, pilot lamp Chang Liang, surpasses 30S (time is adjustable), and pilot lamp starts flicker, and hummer starts to pipe.
As shown in Figure 3, external interface circuit, single chip machine controlling circuit, clock circuit, power-switching circuit and reset circuit are all arranged on feature board 3, and feature board 3 is arranged on base 4; Display and Alarm Circuit is arranged on display board 2, the outer lampshade 1 that is provided with of display board 2.Lampshade 1 adopts high transparent, high heat-resisting engineering PC material cold-resistant, nontoxic, that can freely dye injection molded, base 4 adopts the good PBT material of anti-flammability, the combination of bi-material, makes status indicator lamp lamp housing aspect light transmission, thermotolerance, anti-flammability and impact resistance, have good performance.For the demand of customer in response, lampshade color is according to orange-yellow design.
