Description

Safety hammer intelligent reminding system

Technical field

The utility model is related to technical field of fire safety, and in particular to a kind of safety hammer intelligent reminding system.

Background technology

Safety hammer is a kind of secondary means of escape in closed in spaces.Currently, on motorbus or bus all It is provided with safety hammer, under emergency situations, passenger safety hammer can be used to break vehicle window into pieces and escape.Currently, safety hammer is for side Just quickly remove, be directly inserted in vertical seat, due to by bus may be more crowded, exist and accidentally touch safety hammer The possibility fallen also has individual passengers out of curiosity to remove safety hammer and do not put back to original position in time, if these phenomenons cannot by and Shi Faxian causes safety hammer to be lost, and the life security of a vehicle passenger can be involved in clutch.

There are related technical personnel to devise antitheft safety hammer, such as Publication No.【CN205098128U】, entitled【Automatic report Alert prompt safety hammer】Patent document, describe and magnetic switch, battery, loudspeaker constituted into simple series circuit, work as safety hammer Switch is closed when far from magnetic switch, and loudspeaker send out sound and remind on position of worker safety's hammer not belonging to it.But This method needs a set of independent alarm system, completely separate with the circuit system of automotive interior, increases the complexity of system Degree also just reduces stability, and maintenance is also required to individually be compared trouble, and correspondingly cost can also increase.

Invention content

Purpose to be solved in the utility model is to provide a kind of safety hammer intelligent reminding system, is carried with solving existing safety hammer Device hardware configuration of waking up is complicated, safeguards inconvenient, technical problem of high cost.

In order to solve the above technical problems, the utility model adopts the following technical solution：

A kind of safety hammer intelligent reminding system, including control mechanism and sound generating mechanism are designed, control mechanism includes driving three Pole pipe T1, switching transistor T2, tongue tube and relay one, wherein triode T1 and T2 are in parallel, and when T2 is connected, T1 is short Road, when T2 ends, T1 conductings；Relay one and triode T1 series connection, when T1 is connected, have electric current to pass through in relay one, Tongue tube is series between the base stage B of triode T2 and emitter E；Safety hammer is set to the corresponding position of tongue tube, and Inside is equipped with magnet, and when safety hammer is close to tongue tube, the contact in tongue tube is attracted, circuit turn-on；Sound generating mechanism includes Prompt tone output interface, relay two and loud speaker are carried by the closure of two contact of relay come whether controlling loudspeaker sends out Show that sound, the induction coil of relay two are connected with the normally opened contact of relay one, by increase relay two by generating mechanism with Control mechanism is isolated, and interfering with each other therebetween is prevented.

Further, relay two be single-pole double-throw relay, movable contact and loudspeaker in series, stationary contact one with prompt Sound output interface is connected, and stationary contact two is connected with vehicle-mounted voice output interface.

Further, triode T2 is PNP triode, and collector C connects with the base stage B of the triode T1, emitter E Ground connection, when base stage B is low level, T2 conductings.

Further, triode T1 is NPN triode, collector C phases corresponding with the induction coil of the relay one Even, when base stage B allocates for height, T1 conductings.

Further, power supply used is Vehicular accumulator cell, need not add power supply unit, simplifies circuit structure.

Compared with prior art, the advantageous effects of the utility model are：

1. the utility model is simple in structure, safety hammer prompting is incorporated by vehicle-mounted voice broadcasting system by switch element In, to the greatest extent utilize bus itself component, it is not necessary to by its it is discrete be two completely self-contained systems, increase work( Circuit scale is not increased while energy again.

2. the utility model is small, it is easily installed, by triode and relay as control device, can directly collects It can directly be docked with automobile main circuit at the circuit board on circuit boards, obtained, it is easy to implement.

3. the utility model stability is high, control circuit itself uses IC design, and between sound-producing device It is electrically isolated using relay, prevents mutual crosstalk, further improve stability.

4. the utility model is at low cost, convenient for safeguarding, it is not necessary to individually add the components such as battery, loudspeaker, reduce hardware Cost, the switch element used such as triode, relay power consumption itself is also relatively low, also need not individually be safeguarded, be reduced Maintenance cost.

Specific implementation mode

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses It is described in detail the utility model, does not limit the scope of the utility model in any way.

The devices such as involved unit module, parts, structure, mechanism or sensor in following embodiment, such as without especially Illustrate, is then conventional commercial product.

Embodiment 1：A kind of safety hammer intelligent reminding system is the normally opened contact of relay one, left side referring to Fig. 1, K11 Mechanism in order to control, including Vehicular accumulator cell, NPN triode T1 and PNP triode T2 and tongue tube, tongue tube are opened for magnetosensitive Close, when magnetic material close to when, switch be closed.Right side is sound generating mechanism, including relay two, radio interface, prompt tone connect Mouth, vehicle body loudspeaker, the induction coil of relay two are connected by K11 with relay one.The safety hammer normal condition of built-in magnet Under position and tongue tube it is close, so that tongue tube is closed, the base stage B of triode T2 and emitter E short circuit and be grounded simultaneously at this time, Base stage B is low level, PNP triode T2 conductings, current trend battery feed-resistance R1-resistance R3-triode at this time The emitter E of collector C-T2 of T2.To which the base stage B of NPN triode T1 is low level, is in cut-off state, relay Once coil also no electric current passes through, normally opened contact K11 is not attracted, so two no electric current of relay passes through, relay Two contact K21 is thrown in radio interface, normal play voice.

When above-mentioned safety hammer leaves its position, tongue tube disconnects, and PNP triode T2 base stages B and emitter E circuit are disconnected It opens, base stage B is hanging, is high level, and T2 ends at this time, thus NPN triode T1 is high level, current trend accumulator-electricity The emitter E of base stage B-triode T1 of 1-2-triode of resistance T1 is hindered, at this time the collector C and emitter E of triode T1 Conducting, the access that the emitter E of collector C-triode T1 of coil-triode T1 of accumulator-relay one is constituted are led Logical, the coil a little stream of relay one passes through, and normally opened contact K11 is attracted, and relay two is connected to accumulator, has electric current logical It crosses, so that its contact K21 is thrown and send out prompting in prompt tone interface.

The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field Art personnel, can also be to each specific in above-described embodiment it is understood that without departing from the purpose of the present invention Parameter changes, and forms multiple specific embodiments, is the common variation range of the utility model, no longer detailed one by one herein It states.
