Abstract
The invention relates to a novel passive type voice prompting device which has a control angle of larger than 85 degrees and a control distance of 20 meters. The invention can be widely used for the fields of automobiles, elevators, burglary prevention, fire prevention, dangerous area and domestic cooking prompting, answering machines, and the like which need the voice prompting device.
Description
Technical field:
The present invention relates to household appliance technical field, particularly a kind of passive type sound prompt device of novelty.
Background technology:
Jeopardize the occasion of personal safety at some High-Voltage Electrical Appliances, electric substation, high-tension switch cabinet etc., the alarm board of normal high gown one " Keep Clear-High Voltage, and the pedestrian halts ", this alarm board are with the passing of time very easily lost, and are difficult for again night finding, thereby do not have the effect of alarm.
The present invention is intended to overcome the problems referred to above and passive type or voice prompting device that a kind of novelty is provided, the object of the present invention is achieved like this: adopt the infra-red heat electric transducer to make detector, can infer the infrared ray change energy that radiation from human body with the noncontact form, and change it into voltage signal output, make it to amplify the back and trigger special-purpose Chinese alarm integrated device or special-purpose voice suggestion integrated circuit, promote loudspeaker at last and send special-purpose alarm call or dedicated voice prompting sounds such as " having electricity dangerous; please don't be close ", play security alarm effect or dedicated voice suggesting effect.
The present invention has following characteristics:
1, do not need infrared ray and electromagnetic wave emission source and various types of active contact-making switch.
2, highly sensitive, antijamming capability is strong, and range of control is big.
3, can adopt ac-dc dual power supply, low in energy consumption, easy for installation, simple to operate.
4, be particularly suitable for night and dark applications.
5, adopt the Chinese suggestion voice to report to the police, very directly perceived.
6, can be widely used in required fields such as automobile, elevator, antitheft, fire prevention, culinary art, prompting, answering machine.
Brief Description Of Drawings:
Accompanying drawing is a kind of work schematic block diagram of passive type voice prompting device
Embodiment:
The present invention adopts incorporate casing, puts down front panel during work, allows the alarm probe in the face of warning region, the power-on switch, and relay indicating light is bright, and complete machine is in running order, and this machine pilot angle is greater than 85 °, and its command range can reach 20m.
The infra-red heat electric transducer is made up of high Seebeck coefficient material fit filter glass window, in the time of in human body enters the security area, there is frequency to be about the movable signal of 0.3～5Hz, the infrared ray of human body radiation is focused on the sensor by the paraboloidal mirror with double reflection, the low-frequency voltage signal that sensor output is faint, pass through A1, the amplifier that A2 forms is input to A3 after amplifying, the voltage comparator that A4 forms compares, when the A2 output voltage is higher than the A3 reference voltage, A3 exports high electric rate, A4 exports high electric rate when the A2 output voltage is lower than the A4 reference voltage, thereby make BG1, the complex pipe conducting that BG2 forms triggers the language integrated circuit, and the promotion loudspeaker sends alarm call after BG3 amplifies, and makes people's vigilance away from the explosive area.
Claims (3)
1. passive type verbal cue device, it is characterized in that by: infra-red heat electric transducer device, signal relatively amplifying circuit, trigger control circuit and Chinese speech prompting integrated circuit etc. are constituted.Adopt the 8V power supply, Chinese speech prompting integrated circuit provides by the 3V stabilivolt.
2. a kind of passive type voice prompting device according to claim 1, it is characterized in that the integrated circuit voltage scope of language is that 2.5～4.5V static working current is 0.45mA, working temperature is-10 ℃～70 ℃.
