Background technique
In recent years, the fast development of highway in China transport development, vcehicular tunnel quantity and mileage number have occupied the first in the world, The car ownership in China is also rapidly increasing simultaneously.But the probability for therefore causing tunnel fire hazard generation is also substantially increased, e.g., The especially big tunnel fire hazard accident in Shanxi " 3.1 ", Wuxi " 7.4 " tunnel fire hazard etc., all cause mass casualties and property loss, These painful cases have beaten alarm bell to people, therefore, strengthen, improve the means of tunnel fire hazard alarm, at very urgent The problem for needing to solve.
Fast, toxicity is big, hardly possible is evacuated in rescue, quickly disposition is difficult and control force can not rapid deployment with spreading for tunnel fire hazard The features such as, how quickly and effectively to find that fire behavior is the problem that the needs of the most important thing solve.
Existing tunnel Fire-alarming System (see figure 1) is mainly by fire detector, manual alarm button, fire alarm Host, PLC (programmable logic controller (PLC)), Ethernet switch and monitoring center fire alarming and controlling computer composition.Fire Detector is responsible for round-the-clock induction and feeds back fire signal, and manual alarm button provides the artificial alarm signal in scene of fire, fire The signal that calamity alarm host machine is provided according to fire detector issues the judgement signal for fire behavior whether occur, (programmable to patrol via PLC Volume controller) and Ethernet switch be transferred to monitoring center fire alarming and controlling computer, wherein PLC (programmable logic control Device processed) it can be turned on or off related fire according to the operational order of monitoring center fire alarming and controlling computer offer and visit Survey signal path.
Existing tunnel Fire-alarming System has the following problems:
1, because the communications protocol of existing each producer's alarm host machine is inconsistent, therefore the poor compatibility of product, later maintenance investment Height causes system upgrade and extension restraining factors more;
2, wire rod usage amount is big, while cable causes cable communication quality unstable because of humidity, aging, vehicle accident damage The phenomenon that determining, being also easy to produce wrong report and communication disruption, and the communication modes degree of reliability is not high, communication cable interrupts at single one, It just will affect entire fire alarm system to break down;
3, intelligent level is low, is only capable of knowing whether that fire, nothing occurs by monitoring center fire alarming and controlling computer Method learns fire information by mobile terminal device;
4, equipment is expensive, and existing fire alarm host price is up to more than ten ten thousand, and its processing fire signal ability is remote Not as good as the fire alarm host of civilian three or four thousand yuan of desktop computers.
Summary of the invention
In order to overcome, tunnel fire hazard automatic alarm system compatible extensions are poor, later maintenance difficulty is big, reliability is not high, intelligence The horizontal disadvantage low, at high price of energyization, the purpose of this utility model is that: a kind of high-intelligentization is provided, high reliability is easy to The tunnel fire hazard automatic alarm tele-control system of compatible extensions and later maintenance.
The utility model is realized in this way:
The tunnel fire hazard automatic alarm system, mainly by fire detector 1, manual alarm button 2, wireless control module 3, mobile terminal 4, monitoring center fire alarming and controlling computer 5 form.
Fire detector 1, manual alarm button 2, wireless control module 3 are located in tunnel wall, and mobile terminal 4 can be with The equipment such as mobile phone, iPad are the carrier realized.
Wherein wireless control module 3 are based on Lora agreement, and it is the U.S. which, which is one of LPWAN communication technology, A kind of overlength distance wireless transmission scheme based on spread spectrum that Semtech company uses and promotes.This scheme changes Mode is considered about the compromise of transmission range and power consumption in the past, is provided one kind for user and is simply able to achieve remote, long battery Service life, large capacity system, and then extend sensing network, Lora technology has remote, low-power consumption (battery life is long), more piece The feature of point, low cost.
Wireless control module 3 is by input port, signal processing circuit, Internet of Things submodule, power supply processing circuit, power supply Battery composition.
The received data of input port handle and by Internet of Things submodule via neighbouring 4G by signal processing circuit The transmission modes such as base station or optical fiber are transmitted to monitoring center fire alarming and controlling computer 5 and mobile terminal 4.
The voltage that power supply processing circuit is responsible for providing supplying cell is handled, to reach Internet of Things submodule and letter The operating voltage of number processing circuit.
Internet of Things submodule uses Semtech company SX127X chip, which is jumped using the long-range band spectrum modulation of Lora TM Frequency technology is mainly used for requiring the environment of internet of things of remote transmission, strong antijamming capability, low-power consumption.The chip is by wireless controlled The signal that signal processing circuit provides in molding block 3 is sent to the base station 4G nearby after carrying out band spectrum modulation frequency hopping, via the base station 4G It is transmitted to monitoring center fire alarming and controlling computer and mobile terminal.
The tunnel fire hazard automatic alarm tele-control system of the utility model is a kind of on-line monitoring, real-time perception, long-range The fire protection alarm system of monitoring.In system operation, 1 round-the-clock running of fire detector, the moment monitors fire information;Hand Dynamic alarm button 2 provides the artificial alarm signal in scene of fire;Wireless control module 3 directly acquire fire detector 1 and manually The signal of alarm button 2 is simultaneously back to monitoring center fire alarming and controlling computer 5 by optical fiber or 4G;Mobile terminal 4 It can check the information in each tunnel, each point at any time by cloud platform and monitoring center fire alarming and controlling computer 5.
The tunnel fire hazard automatic alarm tele-control system of the utility model has following features,
Networking flexibility: need to only connect with front-end detector, and wireless control module is power autonomous, without being routed,
It is technologically advanced: to use state-of-the-art Internet of Things mechanics of communication;
