Abstract
The utility model relates to a speech safety alarming device, which comprises a shell, a power circuit, a sensor, an operational amplifier, a power amplifier and a speaker, wherein, the power circuit, the sensor, the operational amplifier, the power amplifier and the speaker are arranged inside the shell. The utility model is characterized in that the sensor is an infrared sensor. A speech circuit block is connected with the back of the operational amplifier. The output terminal of the operational amplifier is connected with the input terminal of the speech circuit block. The output terminal of the speech circuit block is connected with the input terminal of the power amplifier. The output terminal of the power amplifier is connected with the speaker. The utility model which has advantages of fast alarm, good effect and high safety factor is especially suitable for being used in industrial and mining establishments.
Description
The utility model is a kind of industrial and mining enterprises safe operation language safety alarms.
The warning setting of adopting in existing enterprise's operation, the general warning sign that adopts, it also can play the warning effect to people, but can not show a candle to language and can warn the dangerous place of people like that definitely, in time, electric region in factory's inner high voltage electricity zone, the switchgear building for example, warning sign is made warning usefulness all to use " have electricity dangerous, please don't be close " in the past, but often some careless person still can be injured, in order to improve the one-tenth efficient of warning, should design a kind of new type of safe warning device.
The purpose of this utility model is to design a kind of language safety alarm that just has language to warn danger before people arrive the explosive area, so that people can in time, correctly learn danger, and self-protecting rapidly.
The purpose of this utility model is to realize like this, a kind of language safety alarm, include housing and be located at housing interior sensor, power circuit, transport and placing device, amplifirer, loudspeaker, it is characterized in that sensor adopts infrared ray sensor, behind transport and placing device, connect a sound circuit piece, the output terminal of transport and placing device and sound circuit piece input end link, and sound circuit piece output terminal and amplifirer input end link, and amplifirer output is joined with loudspeaker.
The alarm of said structure, when the people walk close to the explosive area also have far from the explosive area quite apart from the time, infrared sensor sends signal at once, this signal triggers the language circuit block after transport and placing device amplifies, its output is after amplifirer amplifies, directly broadcast and give the warning language that is arranged at the language circuit block earlier, thereby the people near the explosive area is left jeopardously immediately by loudspeaker.
The advantage of this language safety alarm is for reporting to the police in advance, in time, and alert rate height carried in language, warning is strong, reports to the police into the efficient height.
Come further the structure of language safety alarm is described in detail with embodiment and accompanying drawing thereof below.
Embodiment language safety alarm
Description of drawings
The electrical structure synoptic diagram of Fig. 1 present embodiment
By as seen shown in Figure 2, present embodiment is made up of elements such as power circuit, infrared ray sensor, transport and placing device, language circuit block, amplifirer, loudspeaker and the resistance that is complementary with it, electric capacity, voltage stabilizers, wherein: power circuit for by transformation for rectifying and voltage-stabilizing filtering again behind the～9V, voltage stabilizing obtain+6V and+the 3V power supply supplies with amplifirer, transport and placing device and language circuit block respectively.
Infrared sensor is selected the BH9402 type for use, and D is for connecing power supply in its connection terminal, and its S is an output terminal, and it is connected G ground connection with the input terminal 14 of transport and placing device.
Transport and placing device is selected BISS0001 type integrated package for use, and its terminal 8.9 connects supply voltage, 7 ground connection, and 10 through resistance R
2Ground connection, 14 is input end, and 2 is output terminal, and it is through R
11The back links T with the grid of triode T1
1Emitter divide two the tunnel, one and language circuit block input end 15 link, its another through R
15Ground connection, T
1Collector and power supply join ， And through capacitor C
10Ground connection, transport and placing device terminal 1 joins with switch SW, and 1 and power supply+6V of the contact of SW switch join, make and break contact 2 ground connection, terminal 3,4, terminal 5,6, terminal 12,13, resistance, electric capacity that terminal 16,15 is complementary with it respectively link.When switch SW is located at 1 position, be high level, this transport and placing device can trigger repeatedly, and is low level when being arranged at 2, then can only trigger once, as removing trigger pip, then must make its outage, works after resetting then again.
The language circuit block is selected SR4013 for use, its terminal 12,8 connects supply voltage, terminal 12,15 is an input end, it links with collector, the emitter of triode respectively, terminal 7 is output, it links with the input end 1,2 of amplifirer TDA7052 behind resistance R 17 and capacitance-resistance filter, the terminal 1,2 of language circuit block respectively with two light emitting diode G
1, G
2One end links, G
1, G
2The other end and terminal 3 link.
Its output terminal 5,8 of amplifirer TDA7052 and loudspeaker link, and its terminal 1 meets power supply+6V, terminal 6 ground connection.
Foregoing circuit is placed in the housing, form a language alarm, through on probation, when People's Bank of China at a distance from alarm 5-8 rice, alarm sends " electricity is arranged, and Danger! Keep Away " or " site examining and repairing please don't close a floodgate " etc. immediately and warns language, thereby play the effect of reporting to the police in advance, and terminal 12,13 capacitor C that end connects of transport and placing device BESS0001
2, resistance R
5Parallel circuit makes it have time-lag action, thereby it is fast not only to report to the police, and it is effective, thereby safety coefficient is improved greatly, and industrial and mining enterprises' safe operation work is had great practicality.
