Description

Fire-fighting remote cluster network monitoring purpose monitoring device

The utility model relates to fire-fighting remote cluster network monitoring purpose monitoring device technique field.

Present fire protection equipment control is independently single, and management is got up and do not concentrated, and is more scattered, occurs can only reporting to the police behind the fire-fighting signal, can not accept control command, and automaticity is very low.

The purpose of this utility model is a kind of fire-fighting remote cluster network monitoring purpose monitoring device of design, because it is made up of multichannel surveillance monitor observation circuit, and by telephone line signal is transmitted, realized the fire-fighting surveillance monitor monitoring to a plurality of scenes a Surveillance center.

The utility model is achieved in that fire-fighting telemonitoring purpose monitoring circuit I 16 is connected with surveillance monitor monitoring computer 13 by telephone wire, and fire-fighting telemonitoring purpose monitoring circuit N17 is connected with surveillance monitor monitoring computer 13 by telephone wire; The composition of each fire-fighting telemonitoring purpose monitoring circuit is: switching value input circuit 1 its input connects fire-fighting equipment fault-signal and alarm signal end 14, its output connects central processing unit (CPU) (CPU) 3, data acquisition circuit 2 its inputs connect fire-fighting equipment real-time data acquisition end 15, its output connects central processing unit (CPU) (CPU) 3, central processing unit (CPU) (CPU) 3 connects communication interface circuit 5 and relay output circuit 4 respectively, communication interface circuit 5 connects modulator-demodulator I7, modulator-demodulator I7 connects remote control switch 8, gamma camera 11 connection layout image processors 10, this device 10 connects modulator-demodulator II9, modulator-demodulator II9 connects remote control switch 8, remote control switch 8 connects telephone wire 12, and relay output circuit 4 connects executive component 6.

The utility model has the advantages that: this device can detect each on-the-spot fire-fighting equipment in round-the-clock 24 hours, every data of on-the-spot fire-fighting equipment are handled the surveillance monitor monitoring computer that all can be transferred to Surveillance center by telephone wire by analysis arbitrarily, on-the-spot any apparatus breaks down or the fire-fighting signal occurs and reports to the police immediately, voice suggestion Surveillance center, at any time remote control detects each user's fire-fighting equipment working condition, can the control appliance startup stop, the image of field apparatus, the image of scene of fire can be transferred on the computer of Surveillance center by telephone wire.

Below in conjunction with accompanying drawing, the utility model is described further with embodiment:

Fig. 1 catenation principle block diagram, Fig. 2 fire-fighting telemonitoring purpose monitoring schematic block circuit diagram, Fig. 3 fire-fighting telemonitoring purpose monitoring circuit diagram.

In the accompanying drawing: 1, switching value input circuit, 2, data acquisition circuit, 3, central processing unit (CPU), 4, relay output circuit, 5, communication interface circuit, 6, executive component, 7, modulator-demodulator I, 8, remote control switch, 9, modulator-demodulator II, 10, image-processing system, 11, gamma camera, 12, telephone wire, 13, surveillance monitor monitoring computer, 14, fire-fighting equipment fault-signal and alarm signal end, 15, fire-fighting equipment real-time data acquisition end, 16, fire-fighting telemonitoring purpose monitoring circuit I, 17, fire-fighting telemonitoring purpose monitoring circuit N.

Fire-fighting telemonitoring purpose monitoring circuit I 16 is connected with surveillance monitor monitoring computer 13 by telephone wire, and fire-fighting telemonitoring purpose monitoring circuit N17 is connected with surveillance monitor monitoring computer 13 by telephone wire.

Fire-fighting telemonitoring purpose monitoring circuit I 16 courses of work are: when need are seen the fire-fighting image scene, control remote control switch 8 makes surveillance monitor monitoring computer 13 connect by telephone wire 12 and image-processing system 10, each road gamma camera 11 is connected on the image-processing system 10 by video line, the pictorial data that gamma camera 11 is gathered is compressed processing by image-processing system 10, shows on surveillance monitor monitoring computer 13 by modulator-demodulator II9 and telephone wire 12; Control remote control switch 8 makes surveillance monitor monitoring computer 13 be connected with central processing unit (CPU) 3 circuit such as grade by telephone wire 12, when the fire-fighting equipment fault-signal occurs, as fire alarm, when all kinds of external alarm signals such as the fire-fighting water level is too high enter switching value input circuit 1 by fire-fighting equipment fault-signal and alarm signal end, after amplifying, the isolation of photoelectrical coupler U4 is input to the P0 mouth of central processing unit (CPU) (CPU) 3, when CPU detects the variation of P0 mouth, know warning has taken place, warning message is through after the processing of central processing unit (CPU) 3, export by TXD, through the MAX232CPE conversion, be sent to surveillance monitor monitoring computer 13 through modulator-demodulator I7 and telephone wire 12 by TXD232 output; Work as water level signal, the N1 processing and amplifying that signal such as pressure and frequency enters data acquisition circuit 2 by fire-fighting equipment real-time data acquisition end 15 is input to the ACH port (water level signal is input to the ACH7 mouth) of CPU, handle serial port 18 pin that send to CPU through CPU, and, be transferred to surveillance monitor monitoring computer 13 through modulator-demodulator I7 and telephone wire 12 by 14TXD232 output through the MAX232CPE conversion; The control of relay is to realize by the interface chip in the relay output circuit 4 8255, this chip is connected with CPU by data/address bus D0-D7, accept CPU control by the output of PA mouth, the control relay break-make is finished the control to executive component 6 after N2:A and N2:B driving amplification.

Fire-fighting telemonitoring purpose monitoring circuit N17 operation principle is the same.
