Description

A kind of Novel smog warning system
Technical field
This utility model relates to a kind of warning system, is specifically related to a kind of Novel smog warning system.
Background technology
Arriving the present, fire always is one of major casualty of threat public security the most common, most common and social development, breaking out of fire from ancient times, and certainly will cause casualties the loss with property, and so how fire preventing is always up the hot issue that people pay close attention to.
Smoke alarm, also known as fire hazard aerosol fog alarm, Smoke Sensor, smoke sensing device etc., it is simply that by monitor smog concentration carry out reporting to the police realizing fire disasters protection. Traditional smoke alarm is typically all employing simple electronic devices and components composition, mainly include an inductive transducer for monitoring smog, also has a speaker for sending sound, use middle components and parts easily aging, service life is shorter, intelligent relatively low with reliability standard, and wrong report or the phenomenon do not reported to the police easily occur, there is bigger potential safety hazard.
Summary of the invention
This utility model purpose is to provide a kind of Novel smog warning system, uses this system, intelligent higher with reliability, it is to avoid wrong report or situation about not reporting to the police occurs, greatly reduces potential safety hazard, and service life is also longer.
The technical solution of the utility model is: a kind of Novel smog warning system, including,
AD harvester, temperature to external world and smog carry out data acquisition, and convert the analogue signal of collection to digital signal and pass to amplifier;
Amplifier: receive the digital signal of AD harvester transmission, and by signal amplification transmission to processor;
Processor, reception amplifier amplify after signal and carry out logical process, judge smokescope numerical value simultaneously and compare, then by the signal transmission after comparison to warning circuit;
Alarm device, receives the signal that processor sends, and reports to the police according to described signal.
Further technical scheme, described AD harvester includes digital temperature sensor, Smoke Sensor and converter.
Further technical scheme, also includes one for the power supply of system power supply, coordinating with described power supply and be provided with on and off switch.
Further technical scheme, is also associated with controlling button with the control end of described processor.
Further technical scheme, also includes one for receiving processor signal the display device shown, described display device is numeral method device.
Further technical scheme, described processor is single-chip microcomputer.
Further technical scheme, described alarm device is traffic lights alarm and buzzer siren.
The utility model has the advantages that:
1. this utility model gathers signal by AD harvester and transmits to processor, processor judges through logical process and sends the signal to warning circuit, if smog exceeds standard, alarm device is reported to the police, whole device is intelligent and reliability is higher, avoid the occurrence of wrong report or situation about not reporting to the police, greatly reduce potential safety hazard, and service life is also longer;
2. this utility model AD harvester includes digital temperature sensor and Smoke Sensor, it is possible to temperature and smog being carried out information gathering, accuracy rate is higher simultaneously;
3. this utility model also includes a display device, and described display device can show smoke monitoring information, more intuitive and convenient in time;
4. this utility model simple in construction, easy to use, it is suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is the block diagram of this utility model embodiment one.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described:
Embodiment one: shown in Figure 1, a kind of Novel smog warning system, including AD harvester, temperature to external world and smog carry out data acquisition, and convert the analogue signal of collection to digital signal and pass to amplifier; Described AD harvester includes digital temperature sensor, Smoke Sensor and converter.
Amplifier: receive the digital signal of AD harvester transmission, and by signal amplification transmission to processor;
Processor, reception amplifier amplify after signal and carry out logical process, judge smokescope numerical value simultaneously and compare, then by the signal transmission after comparison to warning circuit; Described processor is single-chip microcomputer.
Alarm device, receives the signal that processor sends, and reports to the police according to described signal; Described alarm device is traffic lights alarm and buzzer siren.
Also include one for the power supply of system power supply, coordinating with described power supply and be provided with on and off switch, select the aneroid battery of 3 joint 1.5V to power to circuit as power supply.
Digital temperature sensor adopts BS18B20 temperature sensor.
Smoke Sensor adopts MQ-2 gas sensor, can first carry out signal mode number conversion and be transferred to processor again and process, can arrange smokescope and high temperature alarm value.
Being also associated with controlling button with the control end of described processor, devise four buttons in native system altogether, respectively arrange key, plus key, subtract key, alarm keys, when encountering very situation, can push for emergency key, and alarm device is reported to the police.
Processor adopts STC series monolithic.
Alarm device adopts traffic lights alarm and buzzer siren.
Also including one for receiving processor signal the display device shown, described display device is numeral method device.
Native system is in use, utilize digital temperature sensor and Smoke Sensor that smokescope situation in region is effectively monitored, send analogue signal to converter, converter is to converting analog signals into digital data transmission to single-chip microcomputer, received information is detected and judges comparison by single-chip microcomputer, and sends the control signal after processing to display device and alarm device.Specifically, the smoke degree of sensor acquisition, utilize the minimum voltage signal of its release, under amplifier effect, signal is amplified, the voltage signal becoming relatively large is input in single-chip microcomputer; Then, single-chip microcomputer carries out logical process, and real smokescope information is exported numeral method device show, comparison simultaneously judges that whether the numerical value of smokescope is more than the warning marginal value set, if concentration numbers is less than marginal value, then the green light of traffic lights alarm is maintained for long-time not OFF state; If concentration numbers is more than the warning marginal value set, then when sending alarm, red light glimmers always, and buzzer siren sounds.
Certain above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this. All modifications done according to the spirit of this utility model main technical schemes, all should be encompassed within protection domain of the present utility model.
