Description
Technical field
The utility model relates to intelligent measurements and voice reminder control system technical field, and in particular to a kind of multi-functional language
Sound alarm set.
Background technique
With the quickening of social development speed, people's lives rhythm is also getting faster.People are always possible to forget
Some things neglect certain danger in fixed place, and a kind of convenient and simple tool is needed to go to remind people some
Thing.But current technology is mostly some alert devices without detection function or has been with detection device but function
It is incomparably single such as to prompt danger etc., and there is wrong report to a certain extent in the accuracy deficiency of human testing.
Summary of the invention
Problem to be solved in the utility model is: providing a kind of multifunction speech alarm set, which mentions
Awake device not only can solve the single problem of product function, and also can solve has the problem of wrong report without detection or detection.
The utility model in order to solve the above problem provided by technical solution are as follows: a kind of multifunction speech alarm set, packet
Include miniature control unit, infrared sensor of the human body, display module, voice module and playing device；
The infrared sensor of the human body, miniature control unit, display module are sequentially connected electrically, the infrared sensor of the human body
Based on infrared human body heat releasing testing principle and directly export a stable digital signal；The miniature control unit can receive
The digital signal that infrared sensor of the human body transmits；
The miniature control unit, voice module, playing device are sequentially connected electrically, speech chip built in the voice module
And RAM card, the voice module can directly read the recorded message in RAM card and be played back using the playing device.
Preferably, the infrared sensor of the human body is pir sensor.
Preferably, the pir sensor there are two and two pir sensors during installation from a distance.
Compared with prior art, the utility model has the advantages that: the utility model can solve the problem of no intelligent measurement,
Rate of false alarm existing for detection can be greatly reduced, the audio-frequency information conveniently and efficiently played using RAM card memory change,
Multiple functions are made to concentrate on a device embodying.Stable structure is reliable, easy to operate understandable.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model
Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model
Improper restriction.
Fig. 1 is the system diagram of the utility model
Fig. 2 is the control flow chart of the utility model.
Attached drawing mark: 1. people, 2. infrared sensor of the human body, 3. infrared sensor of the human body, 4. miniature control units, 5. displays
Module, 6. voice modules, 7. playing devices.
Specific embodiment
The embodiments of the present invention is described in detail below in conjunction with accompanying drawings and embodiments, whereby to the utility model
How applied technology method solves technical problem and reaches the realization process of technical effect to fully understand and implement.
Specific embodiment of the utility model is as shown in Figure 1 to Figure 2, a kind of multifunction speech alarm set, including miniature
Control unit, infrared sensor of the human body, display module, voice module and playing device；
The infrared sensor of the human body 2, miniature control unit 3, display module 5 are sequentially connected electrically, and the human body infrared passes
Sensor based on infrared human body heat releasing testing principle and directly exports a stable digital signal；3 energy of miniature control unit
Enough receive the digital signal that infrared sensor of the human body transmits；
The miniature control unit 4, voice module 6, playing device 7 are sequentially connected electrically, voice built in the voice module
Chip and RAM card, the voice module can directly read the recorded message in RAM card and be played out using the playing device
Come.
The infrared sensor of the human body is pir sensor；There are two the pir sensors and two pir sensors are being pacified
When dress from a distance；The sensor is based on infrared human body heat releasing testing principle and the directly stable number of output one is believed
Number, false triggering is not present in strong interference immunity, and two sensors judge the process of human body from a distance.
Miniature control unit (MCU) is used to do the control centre of the core of device, event triggering, and there are two the peripheries on basis
Circuit: reset circuit and crystal oscillating circuit, the function of reset circuit are the restoring circuits in some exceptions that device is likely to occur
It works normally, crystal oscillating circuit can provide duty cycle and sprocket pulse signal for CPU.
Display module be shown with charactron alarm clock time reminding or the remembered number of display number.Voice module be
Added peripheral circuit on the basis of speech chip makes speech chip and CPU's to exchange simpler convenience, and in speech chip
On the basis of added RAM card and carry out stored voice message.Playing device uses the loudspeaker of 0.5W, and being easily understood, cost is relatively low.
Referring to Fig.1, which separates a distance with two pir sensors and is connected respectively to again
In miniature control unit, tiny cells are connected to speech chip and charactron, and speech chip connects RAM card and loudspeaker.With only
The hand of vertical the time setting and recorded message that the switching, timing function that cannot exist simultaneously function are controlled by CPU is keyed to
Dynamic broadcasting etc..There are sequencings on two pir sensor detection human body elapsed times, can be judged by the sequencing
Messenger leaves or enters, and determines the recording that should finally play with this, and recording can have multiple, passes through CPU
Control instruction determine the recording specifically played, show the number that messenger enters and leaves on display module.If it is fixed to be provided with
When playing function then when the time arrives, triggering is interrupted, the cpu instruction needed into interrupt function processing plays specified recording,
The time is shown on display module.
The beneficial effects of the utility model are: the utility model can solve the problem of no intelligent measurement, it can be significantly
Ground, which reduces, detects existing rate of false alarm, and the audio-frequency information conveniently and efficiently played using RAM card memory change makes multiple functions
It concentrates on a device embodying.Stable structure is reliable, easy to operate understandable.
Only the most preferred embodiment of the utility model is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above embodiments, and specific structure is allowed to vary.It is all in the utility model independent right
It is required that protection scope in made various change in scope of protection of the utility model.
