Description
Technical field
The invention belongs to safety monitoring field, and in particular to a kind of life security suitable in the confined space is monitored automatically
And early warning system.
Background technology
The various confined spaces are widely there are in life, such as：The automobile of closing is interior, the underground tunnel of improper ventilation
Road and sub-terrain mines hole, freezer, nuclear island inside etc..It is various to occur also to be appeared in the newspapers repeatly in the life security accident of the confined space
End.By such accident of network analysis, find such accident nothing more than two aspect the reason for：In space gaseous environment it is abnormal and
Comfort standard of the temperature beyond human body.
The content of the invention
For problem above, the invention provides a kind of monitoring and the early warning automatically of life security suitable in the confined space
System, can simultaneously detect two parameters of pernicious gas and temperature.There is life in the confined space when life detection module is detected
When detection parameter in body, and environment exceeds given threshold, the warning circuit of control main frame is triggered, produce alarm.In view of this
The different condition of system application scenarios, the detection parameter alarm threshold value of sensor assembly, life entity detection range be designed as it is adjustable,
In can effectively solving the problems, such as background technology.
To achieve the above object, a kind of special life security suitable in the confined space of offer of the present invention is monitored and pre- automatically
Alert system, moves monitoring and early warning system, and the confined space refers to totally-enclosed or partially enclosed, passes in and out stenostomia, improper ventilation
Space,
Automatically monitoring and early warning system include power supply, control main frame, audible-visual annunciator and sensor to described life security
Module, sensor assembly can detect 3 parameters：Pernicious gas, temperature, infrared ray life entity.When sensor assembly has been detected
When temperature, harmful gas concentration in limit space exceed given threshold and have life entity, the warning circuit of control main frame is triggered,
Audible-visual annunciator is promoted to produce alarm, while the wireless signal transmission circuit of control main frame sends distress signal.Sensor assembly
3 detection ranges of parameter can respectively be adjusted（Or distance) and corresponding alarm threshold value, adapt to different size of monitoring space
And various monitoring of environmental, realize optimal automatic monitoring effect.
Described power supply is direct current 12V safe voltages.
The audible-visual annunciator can have according to the interface of specific environment requirement selection control main frame, selectable type of alarm
Single audible alarm, monochromatic light alarm, acousto-optic mixing alarm；The wireless signal transmission circuit of control main frame can send alarm signal simultaneously
Number, the Portable movable control terminal of controllers is triggered, send vibrations, audible alarm.
The sensor assembly includes 3 parts：Temperature detecting module 41, the detection of pernicious gas detection module 42, life
Module 43.3 outputs of monitoring modular access three input nand gates 44, and when pernicious gas too high levels, temperature is too high, have life
During body, three monitoring modulars export high level to NAND gate circuit, and NAND gate is output as a low level by holding wire 46
Signal, triggers the warning circuit of control main frame, and alarm is produced by audible-visual annunciator.
The signaling interface of the sensor assembly is 3p interfaces, including power line 47, ground wire 48, holding wire 46, sensor
Module also includes a power supply module 45.Wherein red line（47）It is power line, black line（48）It is ground wire, blue line（46）It is signal
Line.
The temperature detecting module 41 both can high temperature alarm, also can low-temperature warning.During implementation, according to specific requirement to control
Main frame is configured.Sensor probe is made watertight transducer, can be exposed in the environment according to specific requirement, can also be embedded in interior
Wall.
The pernicious gas detection module 42 can detect multiple gases, to realize various different detection environment.It is specially whole
Individual module uses identical external circuit, gas sensor to use MQ serial gas（Including CO2、CO、LPG、CH4Deng）Sensor,
The sensor different load resistance R of adapted againL, realize matching for gas concentration and output voltage and external circuit.External circuit
Signal transacting is carried out using microprocessor, the function of comparator is performed.In addition, it also has temperature-compensating, automatic calibration
Deng the utility function not available for some traditional comparators.Required according to specific detection, from corresponding gas sensor and
The load resistance R for matching somebody with somebodyL, you can realize testing goal.
The life detection module 43 uses a kind of pyroelectric infrared sensor, for detect in place whether someone or dynamic
Thing, so as to export corresponding electric signal.It is made up of ceramic oxide or piezolectric crystal unit, and electricity is made on two surfaces of element
Pole, when temperature has the change of Δ T in the range of Sensor monitoring, pyroelectric effect can produce electric charge Δ Q on two electrodes,
A faint voltage Δ V is produced between electrodes.Because its output impedance is high, there is a field-effect in the sensor
Pipe carries out impedance conversion.Electric charge Δ Q produced by pyroelectric effect can be combined and disappeared by the ion in air, that is, work as environment
When temperature stabilization is constant, Δ T=0, then sensor is without output.When human body enters detection zone, because human body temperature and environment temperature have difference
Not, Δ T is produced, then there is Δ T to export；If human body enter detection zone after it is motionless, temperature is not changed in, and sensor is not also exported
.To realize requirements above, inductive probe used is popped one's head in using double base, and the window of probe is rectangle, double base（A units B units）Position
In the two ends of longer direction, when human body from left to right or is from right to left walked out-of-date, infrared spectrum reaches the time of double base, distance to be had
Difference, difference is bigger, sense it is sensitiveer, when human body move towards to pop one's head in from front or from top to bottom or from top to bottom direction walk it is out-of-date,
Double base can't detect the change of infrared spectrum distance, without difference, therefore senses insensitive or does not work；So when installing inductor
The direction of the probe double base direction most with physical activity should be made as far as possible parallel, it is ensured that successively by probe double base when human body passes through
Sensed.In order to increase sensing angular range, this module installs round lens additional, also causes that probe four sides all senses, but left and right two
Side is still bigger than upper and lower both direction induction range, sensitivity is strong.
The sensor assembly detection range（Or distance）It is adjustable, its specific detection range such as table 1 below, alarm threshold value
Adjustable range is full detection range.
The detection parameter list of the sensor assembly of table 1
Compared with prior art, the beneficial effects of the invention are as follows：Powered using the safe voltage of 12V, can prevented
Because of hair contingency；Alarm equipment alarm mode is various, can effectively arouse attention, and makes captive out of danger as early as possible；Sensor
Install, adjust simple and convenient, principle is simple, cheap, it is possible to achieve preferable Detection results；Whole system simple structure,
It is easy to use, it is adaptable to various confined space scenes, it is suitable to promote.
