Description
The technical field is as follows:
the utility model relates to a fire alarm technical field, concretely relates to 2 line system fire display panel fire alarm information display system.
Background art:
the fire display panel is connected with the fire alarm controller through a bus, processes and displays data transmitted by the controller, when fire occurs in a building, the fire alarm controller of a fire control center gives an alarm, and simultaneously transmits an alarm signal to the fire display panel in a fire area, and the fire display panel displays the address and related information of a fire alarm triggering component which gives an alarm through the fire display panel and sends out an audible and visual alarm signal. When one controller monitors several floors or fire zones at the same time, a fire display panel may be provided at each floor or fire zone instead of the area alarm controller.
The fire display panel can be divided into three types, namely a digital type, a Chinese character/English type and a graphic type. Traditional digital fire display panel adopts the charactron to show fire alarm's relevant information more, and the charactron consumption is high, when adopting 2 line system bus power supplies, can't realize bus long distance transmission, need additionally increase 24V mains operated usually, adopts 4 line systems promptly, is unfavorable for the construction wiring and reduces construction overall cost. Secondly, the charactron is mostly the cartridge device, and the fire display panel of traditional adoption charactron can carry out fire alarm information display with a plurality of charactrons usually, when printing board production welding components and parts, can not adopt machine automatic weld, and need adopt special frock clamp to fix a plurality of charactrons to can manual or wave-soldering behind the height of same requirement, and production efficiency is low, and the production and processing cost is high. Moreover, each plug-in nixie tube usually has 10 welded pins, and once the plug-in nixie tube is welded and formed on the printed board, if one section of the plug-in nixie tube is damaged or breaks down, the plug-in nixie tube is not easy to detach, and the maintenance and replacement cost of the product is high. In addition, the size of the nixie tube is generally fixed, so the size of the displayed digits cannot be flexibly changed according to the requirements of customers, and if the nixie tube is used for displaying larger digits, special customization is generally needed, so the cost is relatively high. Finally, at present, it is known from the national fire-fighting electronic product quality inspection center that the fire alarm information display method of the 2-wire system low-power consumption fire alarm display panel which is already inspected adopts the traditional nixie tube to display, the lowest power consumption of the action current can only be 5mA, and the lowest power consumption of the 2-wire system low-power consumption fire alarm display panel which adopts the method to display the fire alarm information can be as low as 3 mA.
