Abstract
The present invention discloses an infrared alarm based on a single chip microcomputer, which belongs to the technical field of electronic equipment and mainly solves the problems that a passive infrared alarm in the prior art is not convenient to control remotely, an alarm signal cannot be transmitted to a hand-held device, prompting music is single and so on. The infrared alarm achieves a function for transmitting an alarm signal after detecting invasion of people or animals, at the same time, a bluetooth module of the infrared alarm achieves the situation that equipment such as a mobile phone can control the alarm and receive the alarm signal, a music chip of the infrared alarm achieves selection and adjustment of prompting music, a single chip microcomputer chip of the infrared alarm achieves selection of multiple control modes, and the requirement on a power supply can be satisfied just through a battery. The infrared alarm of the present invention is small in volume, light in weight, can be used for security alert outside a tent during outdoor camping, can be used as a doorbell by switching the music to a visitor welcome mode, and can be used as an infrared module having a bluetooth function to achieve building of a complex system.
Description
Technical field
The invention belongs to technical field of electronic equipment, specifically, relate to a kind of intruder's warning device, particularly a kind of passive infrared alarm of invasion energy effect by heat or optical radiation.
Background technology
Infrared intrusion alarm unit divides active probe and passive detection, and further, passive detection alarm, by the infrared radiation of acquisition environment, through optics into focus, makes pyroelectric electric device produce sudden change electric signal, thus sends alarm sound or light signal.
Existing scheme is as CN203386315U patent " a kind of SCM Based Infrared intrusion detector ", it is the Infrared intrusion detector based on gsm module, in time having people near house, infrared sensor can collect information and be sent to single-chip microcomputer, make alarm send warning after single-chip microcomputer process, send intrusion alarm note to room security simultaneously.Its defect is, one is that type of alarm is single, can only be reported to the police by GSM message.Two is that its alerting signal is provided by gsm system, needs to pay extra running cost.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide one to control at alarm end and to send alerting signal, also control type of alarm by bluetooth equipments such as mobile phones and receive alerting signal, the optional passive infrared alarm of alarm music.
To achieve these goals, the technical solution used in the present invention is as follows:
The present invention comprises with lower component: pyroelectric sensor, pyroelectricity signal processing chip, single-chip microcomputer, bluetooth module, Music Clip and each chip accessory circuit; Described pyroelectricity signal processing chip, bluetooth module, Music Clip are connected with single-chip microcomputer respectively.
Circuit part principle of work is as follows: when there being human or animal to enter sensing range, pyroelectric sensor sends signal, and signal is via processed after pyroelectricity signal processing chip and amplification, and signal is transmitted to single product machine, single-chip microcomputer, according to control program, utilizes Music Clip to play out alarm sound.Single-chip microcomputer also sends signal to bluetooth module simultaneously, and bluetooth module can realize the communication of alarm and the bluetooth equipment such as mobile phone, ipad, thus makes alarm can send alerting signal to mobile phone, and accepts the control of mobile phone.
In control, can by carrying out programming realization corresponding function to single-chip microcomputer.It is including but not limited to following functions: utilize alarm end button to realize controlling the switch of alarm, select music function or alarm function, switch different music, regulate the size of speaker volume, and whether setting allows bluetooth equipment to control.
In the application of Bluetooth function, by comprising the equipment of Bluetooth function, if mobile phone, ipad etc. are by the work of application software control alarm, meanwhile, the alerting signal that alarm sends also can be received.
The selection of various module and chip is as follows: Dan Pinji is including but not limited to AT89C51 chip.Bluetooth module is including but not limited to bluetooth 4.0BLE module.Music Clip is including but not limited to sd8608 Music Clip.Pyroelectricity signal processing chip is including but not limited to BISS0001 chip.
The present invention has following beneficial effect:
(1) this passive infrared alarm is not containing gsm module, without the need to running cost during use.
(2) this passive infrared alarm both can carry out arranging and controlling at alarm end, also can carry out arranging and controlling on the equipment containing Bluetooth function such as mobile phone, ipad;
(3) this passive infrared alarm can, by alerting signal by bluetooth module, send to longer-distance mobile phone, ipad etc. containing the equipment of Bluetooth function.
(4) Music Clip of this passive infrared alarm is integrated with multiple music, according to the setting of operator, can play alarm song, welcome sound, multiple music.Not only can be used as alarm to use, also switch to and welcome voice to realize doorbell function.
