A kind of SOS acoustic-optic alarm being applied to restricted clearanceTechnical field
the present invention relates to a kind of SOS acoustic-optic alarm being applied to restricted clearance.
Background technology
All there is restricted clearance in fields such as oil, chemical industry, pharmacy, smeltings, keep the safety in production that the restricted clearance that defines in industry standard AQ3028-2008 " chemicals production unit restricted clearance job safety specification " is all kinds of towers of chemicals production unit according to the People's Republic of China (PRC) proposed by State Administration of Quality and Technical Supervision, still, groove, tank, burner hearth, drum, pipeline, container and basement, inspection shaft, pond, hole, sewer or other close, semiclosed place.And mostly existing of these restricted clearances is flammable, the hazardous gas such as poisonous, especially in the maintenance repair and maintenance process of restricted clearance, there is larger potential safety hazard, to also not having specially for gas detect and the instruction product of reporting to the police of restricted clearance in current industry, the restricted clearance monitoring of present stage adopts conventional hand-held gas detect product to carry out detecting and reporting to the police mostly, and this mode has significant limitation, there is certain operational hazards simultaneously, when scope of work is larger time, just need multiple gas detecting and alarming instrument to carry out gas safety detection, comparatively waste resource.And mostly operation field is all the intermittent gas-monitoring that carries out at times, once cause danger, also the personnel of hand-held gas detecting instrument are only had to know, and the nerve that some strong poison gas moment just can anaesthetize people is even lethal, other operating personnels at restricted clearance just cannot understand in the very first time generation endangered like this, easily cause serious casualties situation to occur.
In sum, provide a kind of specially for present stage restricted clearance sound and light alarm technology just seem most important.
Summary of the invention
The present invention proposes a kind of acoustic-optic alarm being applied to restricted clearance, the present invention can connect with wireless gas detection alarm device to wirelessly, wireless gas detection alarm device can will measure the dangerous all wireless acousto-optic alarm that just can send in around wireless frequency coverage, the present invention is a kind of wearable device, be worn on the wrist place of personnel, there is monitoring pulse simultaneously, when pulse is too low, send SOS distress signal, there is wireless messages sending function simultaneously.When personnel are because accident, such as gassing shock, heart rate rapid drawdown, is worn on other radio alarming instrument that the sound and light alarm instrument with SOS emergency function on hand will connect towards periphery and sends SOS distress signal, specific sound and light alarm occurs simultaneously and indicates.
the invention provides that one has can monitoring human pulse, sends a kind of SOS acoustic-optic alarm being applied to restricted clearance of the advantages such as emergency alerting signal.
in order to solve the problems of the technologies described above, the invention provides a kind of SOS acoustic-optic alarm being applied to restricted clearance, comprise sound and light alarm control module CPU, acoustic alarm unit, light alarm unit, display unit, wireless module, power supply unit, pulse sensing module, it is characterized in that: described sound and light alarm control module CPU connects acoustic alarm unit, light alarm unit, display unit, wireless module, power supply unit, pulse sensing module respectively.
principle of work of the present invention: the present invention can connect human arm by pulse sensing module, human body beat pulse, test HR Heart Rate, will send alerting signal when exceeding normal range, remind surrounding work personnel and control center, prevent casualties.
the invention has the beneficial effects as follows: the present invention can monitoring human pulse, send the advantages such as emergency alerting signal.
