Description
Technical field
The utility model relates to a kind of smoke alarm unit, especially relates to a kind of intelligent networking formula smoke alarm unit.
Background technology
At present, whether the smog alarm circuit that use in market is according to having network savvy can be divided into free-standing smog circuit (as the MC145010 of Motorola Inc.) and network type warning circuit (as the A5358 of Allegro company), stand alone type smog alarm circuit can only work alone, promptly driving loudspeaker after detecting smog reports to the police, can't with other smog alarm circuit and control desk generation information interaction, the network type warning circuit provides the network alarm function, after the smoke alarm in a certain place detects smog, warning circuit can in time pass smog information, the smoke alarm that can be used to drive other is reported to the police together and is in time withdrawn with the prompting people, perhaps fire information is delivered to far-end control platform, as the strong instrument of remote monitoring and fast processing.
Present most smog alarm circuit all is a network type.The structural drawing of traditional network type smog alarm circuit as shown in Figure 1.Traditional smog alarm circuit provides an IO port, realize the network savvy of smog alarm circuit by this IO port, IO port and power supply ground VSS (line or) in parallel with the IO port of other circuit and VSS together, when a certain circuit is surveyed smog, it can initiatively will be drawn high IO by internal drive circuits, and other circuit that do not detect smog also can enter alarm condition when detecting the IO port and become high level.Two kinds of smoke alarm networked systems of tandem that such smoke alarm can be realized or star formula,
Traditional smog alarm circuit topological structure as shown in Figures 2 and 3.Fig. 2 is a tandem networked system topology diagram.The advantage of tandem networked system is that the interconnection line of smog alarm has only one, and the complicacy of simplified system wiring is saved cost.Inferior position is that far-end control platform can't be discerned the particular location that location smog is detected, and promptly can't discern which smoke alarm and detect smog.Fig. 3 is a star formula networked system topology diagram.Star formula networked system is received far-end control platform with the IO port of each smoke alarm by cable, far-end control platform can realize discerning the function of location like this, if but when system scale was big, the scale of system wiring and complicacy all can be very big, cost is also higher.
