Fig. 3 is a wireless base station of the present invention flow chart;
Among the figure 1, the monitoring subnet, 2, monitoring platform, 3, inductor, 4, the wireless base station, 5,433 frequency ranges, 6, the GS module, 7, cellphone subscriber's end.
Embodiment
Like Fig. 1 is structural representation of the present invention; A kind of wireless fire disaster cluster monitoring system; Form with far-end monitoring platform 2 by 1 ~ 256 monitoring subnet 1; A monitoring subnet 1 is made up of 1 ~ 256 inductor 3 and a wireless base station 4, adopts short range wireless transmission module 433 frequency ranges 5 to carry out data transmission between inductor 3 and the wireless base station 4, and wireless base station 4 is in the position of center line of monitoring subnet 1; The environmental data that each inductor 3 in the monitoring subnet 1 will be gathered separately is sent to wireless base station 4; Wireless base station 4 transmits the data of all inductors again through gsm module 6, the data of all inductors are sent to the monitoring platform 2 of far-end on the one hand, are sent to the cellphone subscriber on the other hand and hold 7.Suppose that the multi-storey building with six layer of three unit, a building is monitored subnet as one among Fig. 1; If fire alarm appears in some inductors in the monitoring network; Monitoring platform triggers in the monitoring network all inductors sound that gives the alarm immediately, and sends the fire alarm note to fire-fighting system through mobile phone or monitoring platform immediately.Since adopt between inductor and the wireless base station in the monitoring subnet be transmission range at 200 meters with interior digital transmission module; So suppose each unit in building, a building and each floor an inductor is installed all, the top for good of temporary location promptly selected in the position of wireless base station so.The present invention adopts the cluster system management pattern.A monitoring platform can be controlled 256 monitoring subnets, and each monitoring subnet can be monitored 256 inductors, has improved monitoring efficient greatly, practices thrift use cost.
As shown in Figure 2, said inductor uses 8051 single-chip microcomputers of standard to be core, wireless data transmission module 433M frequency range, Temperature Humidity Sensor, smoke transducer, hummer and other peripheral circuit of embedded transmission range about 200 meters.The 433M frequency range is free data-transmission mode.Smoke transducer is used for monitoring the situation on fire of family; In case certain situation occurs; Just send alerting signal to the base station, after the wireless base station receives signal, will trigger the onsite alarming system, the onsite alarming system comprises that LCD shows and hummer; And express corresponding situation, trigger buzzer warning and LCD and show fire information.The content of built-in humiture inductor collection is: temperature, humidity, inductor numbering (monitoring address, subnet wireless base station+inductor address).Inductor all is in dormant state beyond data acquisition and data transmission; So consumed power is few; So adopt the power supply of high capacity Ni-MH battery power supply mode, (every batteries is 1.2V to four joints, and 5000mAH) battery series connection back voltage is 4.8V; Be enough to supply with the cmos circuit operate as normal, changed once in per about 2 years through counting cell.Invention need not wiring, and battery altering is convenient.
When system power on start working after, the single-chip microcomputer initialization is interrupted, and reads toggle switch, the inductor numbering, the LCD initialization, the initialization of wireless module state, this shows that single-chip microcomputer begins to inquire about each sensor and whether has signal to spread out of.By the time after having signal to spread out of, on the one hand wireless module begins that data stream is arranged, and data flow instruction possibly be temperature or humidity instruction, and single-chip microcomputer this moment collecting temperature or humidity data again deposit respective memory unit in, at last to wireless base station feedback temperature or humidity data; Smoke transducer is monitored smog on the other hand; If have; Then can send alerting signal to the wireless base station, after the wireless base station receives signal, will trigger the onsite alarming system, the onsite alarming system comprises that LCD shows and hummer; And express corresponding situation, trigger buzzer warning and LCD and show fire information.Thereby, the onsite alarming system takes corresponding processing if knowing the situation of generation at once when above-mentioned situation takes place when making things convenient for the user at home.
As shown in Figure 3, described wireless base station 4 uses 8051 single-chip microcomputers to be core equally, embedded wireless data transmission module, GPS global location module, GSM mobile handset module and other peripheral circuits.Gsm module can send warning information to cellphone subscriber's end and far-end monitoring platform respectively.GPS can read the satnav address information, and alarm set point detail location (like longitude, latitude etc.).
When system started working, the single-chip microcomputer initialization was interrupted, and resets, and embedded wireless module state initialization is in receive status, and this shows that single-chip microcomputer begins request signal, and wireless module is started working.Then wireless module begins that data stream is arranged; The data stream that inductor transmits is the warning message that humiture data or smog cause; If the humiture data stream drives mobile module, humiture is organized into messaging format and sends note to the Security Personnel; If fire alarm information is then sent the fire alarm note to the Security Personnel.In addition, interrupt flag bit can be set, if the signal that transmits is set interruption code, wireless module is received information; Convert the UNICODE sign indicating number of system to the GB2312 sign indicating number, communication protocol identification GB2312 sign indicating number, decision instruction form; Instruction then feeds back to inductor for the collecting temperature instruction, asks for temperature data; Instruction then feeds back to inductor for gathering the humidity instruction, asks for humidity data; Instruction is then changed Security Personnel's mobile phone card storage unit for authorizing the Security Personnel.In addition, the wireless base station will be a gps data (being longitude, latitude) of reading this subnet in breaking out of fire also except will gathering monitoring subnet interoceptor day regular data.
The present invention is powerful, and is practical, adopts the many monitoring points of gsm wireless transmission mode to enlarge the scope of Realtime Alerts, can know scene in detail in addition, lets the householder know through mobile phone, or knows by security through monitoring platform, in time reports to the police and handles.The present invention adopts the cluster system management pattern.A monitoring platform can be controlled 256 monitoring subnets, and each monitoring subnet can be monitored 256 inductors.Each monitoring subnet has improved system's detection efficiency greatly as long as be equipped with a SIM card, practices thrift use cost.In addition, use powered battery, need not alternating current, it is convenient to lay.The present invention has fully studied fire alarm in the market, draws their advantage, adds our method for transmitting signals reliably, can be widely used in places such as sub-district, school, factory, warehouse, market, office building.
