Overall use flow chart as shown in Figure 4, the early warning information such as automatic base station receiving front-end monitoring device temperature, smokescope, combustable gas concentration, it is transmitted to condition of a fire early warning group's auxiliary disposal center, await a response, time-out does not responds acousto-optic hint.Receive after flame light fire alarm information is transmitted to condition of a fire early warning group auxiliary disposal center, wait that there is not reply the scheduled time, start and control the fire extinguishing of remote control fire-extinguishing apparatus.Accepting condition of a fire early warning group auxiliary and dispose center instruction, control remote control camera and take pictures, image, control the fire extinguishing of remote control fire-extinguishing apparatus, and await a response, time-out does not responds acousto-optic hint, and will report the failure to condition of a fire early warning group and assist disposal center.During use, the front end surveillance device of automatic base station subordinate needs to dispose center typing relevant information to condition of a fire early warning intelligence, and reports condition of a fire early warning group's auxiliary disposal center to confirm.And register front end surveillance device log-on message, generate front end surveillance device numbering, distribution network address, collect front end surveillance device installation addresses, the telephone number of director.Time-of-the-day order community is automatically disposed base station and administrative front end surveillance device is forwarded instruction, front end surveillance device normal operation, responds instruction.If there not being response, Advise By Wire this front end surveillance device director, or this community disposes base station director automatically, fixes a breakdown.
Being simultaneously received the parameters such as temperature that front end surveillance device sends, smokescope, combustable gas concentration and reach early warning information and the scene photograph of preset value, show the relevant information of this equipment immediately, send acousto-optic hint, whether artificial judgment scene has people.Someone, Advise By Wire this front end surveillance device director, create forecast information, jealous woman feelings process.Unmanned, Advise By Wire front end surveillance device director, notify that personnel rush towards scene nearby and check.
And receiving the flame optical parameter that front end surveillance device sends and reach fire alarm information and the scene photograph of preset value, send acousto-optic hint, whether artificial judgment scene has people.Someone, Advise By Wire this front end surveillance device director, have occurred and that fire alarm.Unmanned, Advise By Wire front end surveillance device director, notify that personnel rush towards site disposal nearby.Simultaneously according to the photo of the very first time, and instruction is taken pictures again, the on-the-spot condition of a fire information of the acquisition such as shooting judges, decides whether to start remote control fire-extinguishing apparatus, decides whether to 119 report fire alarms.
By said system and control method, it is possible to disposing center by one, multiple places of multiple communities are carried out implementing monitoring, whether the equipment that can check in real time is in unfaulty conditions, and has detected whether that the condition of a fire occurs in real time, the very first time processes information.Fundamentally " fire " is controlled as " condition of a fire ", Alarm is converted into " early warning ", it is ensured that the personal safety as well as the property safety of the people, it is provided that another kind of safety and reliability are strong, automatically control degree high, it is believed that the condition of a fire early warning intelligence disposal system that labor intensity is little.
