2, alarm sound is excessive, and the call of intercom, and exists when passing through residential block at night when interfering normal operation Disturb residents problem；

3, alarm is single, with other alarm indistinctions, is easy to produce the phenomenon that turning a deaf ear to, does not have security alarm Effect；

4, without visible illumination: night grow up industrial siding shunt when, on the way without lighting, the person of connection is needed to use flashlight It voluntarily illuminates, there are security risks；

5, unstable quality, it is perishable, do not have anti-dropping drop.

6, not specific explosion prevention function, so that can not be used in the special purpose railroad for having requirement of explosion proof.

Utility model content

In view of this, the present invention provides portable shunt of one kind to push safety alarm.

In order to solve the problems existing in the prior art, the technical solution of the utility model is: a kind of portable push peace of shunting Full alarm, it is characterised in that: including master board, signal designation module, voice module, lighting module, power supply, charging interface And key indicator lamp；

Signal designation module, voice module, lighting module and the key indicator lamp is connect with master board respectively；

The power supply and charging interface gives master board power supply-charging.

STMicw Electronics STM8003F single-chip microcontroller is selected in the master board.

The model ND061A of the voice module.

The power supply selects 3 section import Panasonic, 18650 battery core in parallel.

Managing chip in the power supply selects specialized lithium battery charging management chip TC4056A.

Compared with prior art, as follows the advantages of the utility model:

1, the utility model alarm uses voice module, exports comprising multilingual alarm voice, so that wide using crowd It is general, it is particularly suitable for railway train arrangement operation personnel；

2, the utility model controls red blue lamp flash for prompting using signal designation lamp module, attracts people's attention strong, alert Show that effect is good；

3, the utility model operating in a key, using a key loop control, it can be achieved that voice size, light switch It opens and closes；

4, the utility model is chargeable；

5, the utility model structure is simple, small in size, can be packed into pocket or hang over loins and carry, and maintenance is convenient.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

The present embodiment provides portable shunt of one kind to push safety alarm (referring to Fig. 1), including master board 1, signal Indicating module 2, voice module 3, lighting module 4, power supply 5, charging interface 6 and key indicator lamp 7；

Signal designation module 2, voice module 3, lighting module 4 and the key indicator lamp 7 connects with master board 1 respectively It connects；

The power supply 5 and charging interface 6 gives 1 power supply-charging of master board.

The power supply 5 selects 3 section import Panasonic, 18650 battery core in parallel.

Managing chip in the power supply 5 selects specialized lithium battery charging management chip TC4056A.

Referring to fig. 2-Fig. 8:

1, after the power supply adaptor access of Fig. 4, management is charged the battery by U2, while battery output switch Q3 is closed It closes, system power supply passes through D1 by adapter, and D3 powers to follow-up system；

2, when Fig. 4 power supply adaptor does not access, battery exports switch Q3 and opens, and battery exports 3.7v cell voltage, battery Voltage boosts to system standard 5v voltage after U1, and 5v voltage is depressured as Fig. 5 MCU operating voltage 3.3V after U4；

3. Fig. 5 MCU enters standby mode after system electrification, detect that button value changes, Fig. 5 MCU enters different operations Mode；

4. Fig. 2 sound control, Fig. 5 MCU transfers voice by special communication protocol control speech chip U3 and plays, Fig. 2 Audio signal is played through power amplifier chips U7；

5. Fig. 3 Lighting control, Fig. 5 MCU output level Fig. 6 signal controls Lighting control chip U6 and drives illumination LED；

6. Fig. 6 Signalized control, Fig. 5 MCU outputs level signals control Q7, and Q8 completes red blue lamp plate flashing；

7. Fig. 7 indicator light circuit, LED operation voltage is 5V, and LED switch is controlled by single-chip microcontroller, when KEY LED is high level When D4 light, when KEY LED be low level when D4 do not work；
