Embodiment
Below the invention is described in further details.
The self-adjustable doorbell of a kind of volume, comprise key-press input unit, human detection unit, main control unit, audio output unit and power supply unit, wherein key-press input unit, main control unit and audio output unit are linked in sequence, human detection unit is connected with main control unit, power supply unit is connected with key-press input unit, main control unit, human detection unit and audio output unit respectively, and described audio output unit and human detection unit one_to_one corresponding are arranged in each room; Described key-press input unit sends information to main control unit after doorbell is triggered; After described main control unit receives doorbell trigger message, send control information to human detection unit; Described human detection unit, after the control information receiving main control unit, detects in room whether have people, has people that feedback information is sent to main control unit if detected in room; Described audio output unit, after the control information receiving main control unit, plays doorbell music; Described power supply unit is used for powering to each unit.
As a preferred technical solution of the present invention: described audio output unit comprises first object volume the tinkle of bells playing module, the second target volume the tinkle of bells playing module and the 3rd target volume the tinkle of bells playing module, the ringing volume of described first object volume the tinkle of bells playing module, the second target volume the tinkle of bells playing module, the 3rd target volume the tinkle of bells playing module increases progressively successively; This doorbell also comprises spatial detection unit, and spatial detection unit is connected with main control unit and power supply unit respectively, and described spatial detection unit for detecting the size in room, and selects the tinkle of bells playing module of different target volume according to the size in room.
As a preferred technical solution of the present invention: described space detection module is Ultrasonic ranging device.
As a preferred technical solution of the present invention: described Ultrasonic ranging device comprises ultrasonic transmitter and ultrasonic receiver.
As a preferred technical solution of the present invention: described human detection unit adopts infrared human body heat releasing sensor.
As a preferred technical solution of the present invention: described power supply unit adopts direct current or Alternating Current Power Supply.
The present invention adopts the method for supersonic sounding to measure the size in room, and accuracy is high.
Ultrasonic ranging principle launches ultrasound wave by ultrasonic transmitter to a direction, while x time, start timing, encounters barrier and just return immediately when ultrasound wave is propagated in atmosphere, and ultrasonic receiver receives reflection wave and just stops timing immediately.The aerial velocity of propagation of ultrasound wave is v, and according to timer record measure transmitting and receiving echo mistiming △ t, just can calculate launching site distance barrier distance S, that is:
S = v·△t /2 ①
So-called mistiming telemetry that Here it is.
Because ultrasound wave is also a kind of sound wave, its velocity of sound C is relevant with temperature.In use, if temperature variation is little, then can think that the velocity of sound is substantially constant.Under normal temperature, hyperacoustic velocity of propagation is 334 meter per seconds, but its velocity of propagation V is subject to the impact of the factors such as temperature in air, humidity, pressure, and the impact wherein by temperature is comparatively large, as temperature often raises 1 DEG C, and velocity of sound increase about 0. 6 meter per second.If distance accuracy requires very high, then should be corrected by the method for temperature compensation.
The present invention adopts infrared human body heat releasing sensor to detect in room whether have people.
The principle of infrared human body heat releasing sensor is as follows: human body has constant body temperature, and generally at 37 degree, so can send the infrared ray of specific wavelength about 10UM, passive type infrared probe carries out work by detecting the infrared ray of about the 10UM of human-body emitting.The infrared ray of about the 10UM of human-body emitting is by gathering on infrared induction source after your the optical filter enhancing of luxuriant and rich with fragrance mud.Infrared induction source adopts pyroelectricity element usually, and this element will lose charge balance when receiving human infrared radiation temperature and changing, and outwards discharges electric charge, just can produce alerting signal after subsequent conditioning circuit processes after testing.
The present invention is very intelligent, according to the size in room, can automatically regulate the size of doorbell the tinkle of bells.Power supply unit of the present invention can adopt direct current supply, and also can adopt Alternating Current Power Supply, selectivity is strong.Doorbell the tinkle of bells broadcasting capable of circulation in the present invention, if indoor noisy, owner also still can hear doorbell the tinkle of bells.
Embodiment one:
When there being people to press bell button, key-press input unit receives information and this information is passed to main control unit, " detection " information is passed to the human detection unit be distributed in each room by main control unit, is arranged in the human detection unit inspection room in each room whether have people; If people detected, then by this information feed back to main control unit; " measurement " information is sent to spatial detection unit by main control unit, measures the size in room.First spatial detection unit starts timing by the first ultrasonic transmitter transmitting ultrasound wave simultaneously, just timing is stopped when the first ultrasonic receiver receives reflection wave, the mistiming of measuring transmitting and receiving echo of timer record, just can calculate the length in room, then launch ultrasound wave by the second ultrasonic transmitter and start timing simultaneously, just timing is stopped when the second ultrasonic receiver receives reflection wave, the mistiming of measuring transmitting and receiving echo of timer record, just can calculate the wide of room, thus the area of calculated room.If the area in room is less than 20 square metres, then first object volume the tinkle of bells playing module is adopted to play doorbell music.If the power supply of doorbell adopts powered battery, if dead battery, can battery be changed.
Embodiment two:
When there being people to press bell button, key-press input unit receives information and this information is passed to main control unit, " detection " information is passed to the human detection unit be distributed in each room by main control unit, is arranged in the human detection unit inspection room in each room whether have people; If people detected, then by this information feed back to main control unit; " measurement " information is sent to space detection module by main control unit, measures the size in room.First spatial detection unit starts timing by the first ultrasonic transmitter transmitting ultrasound wave simultaneously, just timing is stopped when the first ultrasonic receiver receives reflection wave, the mistiming of measuring transmitting and receiving echo of timer record, just can calculate the length in room, then launch ultrasound wave by the second ultrasonic transmitter and start timing simultaneously, just timing is stopped when the second ultrasonic receiver receives reflection wave, the mistiming of measuring transmitting and receiving echo of timer record, just can calculate the wide of room, thus calculate the area installing doorbell room.If the area in room is greater than 40 square metres, then the 3rd target volume the tinkle of bells playing module is adopted to play doorbell music.The broadcasting of doorbell the tinkle of bells can adopt loop play pattern, the tinkle of bells loop play three times.
Above embodiments of the present invention are explained in detail, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from present inventive concept.
