The alarm device is reliable in work and quick in response, and has the advantages of light weight, long service life, long detection distance, and the like.

Description

A kind of moving type security protection autoalarm

Technical field

The utility model relates to a kind of warning device, particularly a kind of moving type security protection autoalarm.

Background technology

During power construction, in order to remind inoperative personnel this place hot work in progress, to note personal safety, need at the scene around pull on warning tape or put the caution heap, have in addition need place the protection entanglement.Though warning tape can play the effect of isolating the working-yard, warning other people with the caution heap, as if having the people to be strayed into or swarming into, is difficult to come to light, and threatens for the safety of the person and equipment, in case have an accident, consequence will be very seriously.In production practices, the security incident that causes thus happens occasionally, and uses warning tape and caution to store up in very big potential safety hazard.In addition, warning tape and caution heap mainly are made of plastics, the easy ageing distortion, and serviceable life is short, can pollute surrounding environment after discarding.Though entanglement is reliable, its cost is higher, transports inconvenience, and (like maintenance etc.) set up entanglement and wasted time and energy for short-period power construction, increased workload greatly.The power industry construction is frequent, and danger coefficient is high, and operating process is complicated, and the requirement of adjusting the distance when power equipment normally moves is also very strict.Anyone is strayed into the workspace, all possibly cause the person or equipment damage.Therefore, moving type security is protected autoalarm be applied in the power construction process, will produce remarkable social benefit and economic worth.

Summary of the invention

The utility model is the problem that exists to the used alarming device of above-mentioned present power construction occasion, has proposed a kind of moving type security protection autoalarm, portably uses convenience, steady quality.

The technical scheme of the utility model is: a kind of moving type security protection autoalarm; Keyboard circuit is sent running parameter into single-chip microcomputer, and testing circuit detects correlation type safety photo-sensor signal will and send single-chip microcomputer, and gsm module is a communication module; Support message function; The single-chip microcomputer deal with data send gsm module through the GSM network note to be sent into the work mobile phone, and simultaneously single-chip microcomputer is with the alerting signal alert circuit alarm of delivering newspaper, and power supply is supplied power for each modular circuit.

Said single-chip microcomputer adopts the AT89C51 single-chip microcomputer.

Said testing circuit adopts correlation type safety light electric transducer as testing circuit.

Said warning circuit adopts to have luminous and acousto-optic group alarm circuit vocal function.

The beneficial effect of the utility model is: the utility model moving type security protection autoalarm, reliable operation; Reaction velocity is fast; Have advantages such as in light weight, long service life, detection distance are big.

Fig. 2 is the utility model moving type security protection autoalarm structural representation.

Embodiment

Moving type security protection autoalarm structured flowchart as shown in Figure 1; Keyboard circuit 2 is sent running parameter into single-chip microcomputer 1, and testing circuit 3 detects correlation type safety photo-sensor signal will and send single-chip microcomputer 1, and gsm module 5 is a communication module; Support message function; Single-chip microcomputer 1 deal with data send gsm module 5 through GSM network 6 note to be sent into work mobile phone 7, and simultaneously single-chip microcomputer 1 is reported to the police the alerting signal alert circuit 4 of delivering newspaper, and power supply 8 is supplied power for each modular circuit.

Moving type security protection autoalarm structural representation as shown in Figure 2; Single-chip microcomputer 1 adopts the AT89C51 single-chip microcomputer; Sheet include 4k bytes can be erasable repeatedly read-only program memory (PEROM) and the Random Access Data storer (RAM) of 128 bytes; Have high density, non-volatile memories characteristics, compatibility standard MCS-51 order set, 8 central processing units of sheet built-in general-purpose (CPU) and Flash storage unit.

Testing circuit 3 adopts correlation type safety light electric transducer (safe grating) as testing circuit.The ultimate principle of this circuit be the light direct beam that sends of illuminator to light-receiving device, form protection light curtain.When the light curtain was blocked, light-receiving device produced a shielding signals, is transferred to processor through signal cable; Processor is handled this signal, produces PNP or relay signal, through signal wire this signal is transferred to single-chip microcomputer 1; Start alert program, control warning circuit 4 is realized security alarm.The composition of this circuit comprises:

1. illuminator: form the emission IR by some luminescent devices.

2. light-receiving device: form by some sensitive devices, accept IR, corresponding one by one with the luminescent device of illuminator, form protection light curtain, produce logical light, shielding signals, through signal cable signal is transferred to processor simultaneously.

3. processor: be illuminator, light-receiving device power supply, and accept logical light, the shielding signals that light-receiving device transmits, output PNP or relay signal, handled easily and light curtain lead to light, the observation of shading state.

4. signal cable: be used for signal between transmission processor and illuminator, the light-receiving device.

5. umbilical cable: be used for connection processing device and single-chip microcomputer, thereby realize security control.

6. mounting bracket: fix illuminator and light-receiving device.In view of power construction environment more complicated, support need carry out particular production.

Warning circuit 4 adopts to have luminous and acousto-optic group alarm circuit vocal function.Adopt the two quick-fried sudden strains of a muscle of LED/multitone alarm combination, this combination has 32 kinds of voice, but the sound and light signal independent triggers, and the volume maximum adjustable satisfies the requirement that install the side to 110dB.

GSM (Global System for Mobile Communications) module 5 has the function of SMS alarm and dialing alarm when carrying out sound and light alarm.When taking place when reporting to the police, the staff possibly not aware the sound and light alarm signal away from the working-yard.Need in time to notify the staff to make reflection through gsm module 5.Adopt the SMS alarm mode,, the form of warning message with note is delivered on staff's mobile phone 7 by single-chip microcomputer 1 control gsm module 5.
