Description
Technical field
The present invention relates to a kind of wireless fire detection alarm, especially a kind of wireless sense cigarettes based on NB-IoT technology
Temperature-sensing fire detecting alarm.
Technical background
Traditional fire detection alarm is typically all following two product, and first is free-standing detecting alarm, that is, is worked as
Occur fire or when other the condition of a disasters can only live ring alarm, information cannot send out, and structure and function is relatively simple, once
Scene is unattended, extraneous to know warning message again, it is possible to cause heavy losses because of fire or other the condition of a disasters；Second
Kind product is wireless smoke detection alarm, that is, has wireless transmission function, but only have smoke detection function, if because in environment
The particulates that the non-fire such as steam, dust, oil smoke generate when occurring enter in smoke detector, and detector is sent out immediately
The case where warning message notifies all parties out, causes false alarm and disturbs residents, such product function is single, and alarm, which can not differentiate, is
It is no because fire causes, once wrong report may cause waste of human resource and bring harassing and wrecking in life to user.
The detecting alarm with wireless communication mode transmission information occurred currently on the market, is generally adopted by GSM/
The wireless technologys such as GPRS, wireless radio-frequency 433MHz, Lora wireless technology transmit signal.GSM/GPRS network coverage
Extensively, the high communication quality, shortcoming are that power consumption is big, generally require external power supply, and hardware cost is high, and usage charges are high.Less radio-frequency
Technology 433MHz is at low cost, and frequency of use belongs to free frequency range at home, but a disadvantage is that communication distance is short, coverage area
Small, the problems such as reliability is low, poor anti jamming capability, is than more prominent.Less radio-frequency Lora technology, communication distance is remote, anti-interference ability
By force, good reliability, moderate cost, but self-built base station (gateway) is generally required, maintenance cost is high.
NB-IoT technology is an emerging technology, support low power consuming devices wide area network cellular data connect, also by
It is called low-power consumption wide area network (LPWA).NB-IoT supports stand-by time length, the efficient connection to network connectivity requirements higher device.
It is said that the NB-IoT device battery service life can be improved at least 10 years, while can also provide very comprehensive indoor cellular data and connect
Connect covering.NB-IOT focuses on low-power consumption and extensively covers the market (LPWA) Internet of Things (IoT), is that one kind can in the world extensively
The emerging technology of application.B-IoT has four characteristics: first is that wide covering, it will thus provide improved in-door covering, in same frequency range
Under, NB-IoT expands 100 times than existing network gain 20dB, area coverage；Second is that have the ability of support magnanimity connection,
Mono- sector NB-IoT can support 100,000 connection, support low latency sensitivity, ultralow equipment cost, low equipment power dissipation and
The network architecture of optimization；Third is that more low-power consumption, the stand-by time of NB-IoT terminal module is 10 years；Fourth is that lower module
Cost, single successive module are no more than 3 dollars.NB-IOT uses License frequency range, can take interior band, protection band or independent load
Three kinds of deployment way such as wave.NB-IoT can be widely applied to Industry Control, safety in production, digital home, intelligent building monitoring
And a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, wisdom agricultural.
Summary of the invention
The purpose of the present invention is to provide a kind of route is reasonable, wireless NB-IoT technology is used, prison can be not only perceived
Whether the smog for surveying scene is exceeded, can also be acquired to monitoring field temperature, issues in the alert signal for having smog exceeded
Afterwards, the temperature of monitoring field is acquired and is calculated immediately, all surpassed when detecting alarm is provided simultaneously with smog and temperature change
When crossing certain standard, alarm sound is issued immediately, and alert notice is externally issued by wireless module immediately, can timely and effectively be risen
To fire monitoring effect and the wireless smoke-temperature sensing detection wireless based on NB-IoT technology of the reduction false alarm of energy high degree
Fire detection alarm.
The purpose of the present invention can be reached by the following measures: a kind of wireless smoke-temperature sensing fire based on NB-IoT technology
Calamity detecting alarm, including smoke detection module, heat detection module, detection processing module, warning circuit, it is characterised in that:
There are also Weak fault indicator lights, wireless NB-IoT transmission module, carry out real-time monitoring to monitoring field by smoke detection module, when
When smoke detection module detects smokescope and reaches alarming value, detection processing module starts heat detection module automatically immediately,
Constantly interval acquisition monitors ambient temperature value and carries out storage and comparing calculation, when collected temperature has apparent raising trend
When, detector processor starts warning circuit immediately to be reminded evacuating personnel while sending alarm by wireless NB-IoT transmission module
Information to remote monitoring center, when collected temperature do not increase trend and temperature it is very low and when stablizing, detection processing mould
Block starting Weak fault indicator light prompt equipment needs maintenance test while being sent information to by wireless NB-IoT transmission module
Fire-fighting maintenance center.
The purpose of the present invention can also be reached by following measures: the warning circuit includes buzzer, alarm flashing light.
The present invention comparison prior art has the advantage that as follows with good effect: the design of this alarm route rationally, is based on
NB-IoT technology and design, using operator base station transmit, stability is strong, high reliablity, strong antijamming capability, transmission range
Far.Using autonomous low-power consumption algorithm, detector can be used 10 years using single battery.Overall cost is low, is not necessarily to self-built base station (net
Close), maintenance cost is low.Detector is provided simultaneously with smog and temperature sensing and acquisition function, not only can be to the cigarette of monitoring field
Mist, which is monitored, can also carry out analytical calculation to the temperature change of monitoring field, can timely and effectively judge the true of alarm
Property, it effectively reduces because of the wrong report bring wasting of resources and harassing and wrecking.Effectively overcome current existing alarm detector product
Wrong report is more, the high disadvantages such as low with communication reliability of the serious, maintenance cost of disturbing residents, can be existing in home dwelling, business premises, industry
The fire-fighting domains such as field play a significant role.
Detailed description of the invention
Fig. 1 is circuit block diagram of the invention.
